heidegger being and time dasein care death temporality
This article offers a comprehensive interpretation of Heidegger's Being and Time, tracing its movement from the question of Being through the existential analytic of Dasein to temporality as the ultimate horizon of understanding. It systematically examines Heidegger's dismantling of the Cartesian subject-object framework through Being-in-the-world, his critique of theoretical knowledge via readiness-to-hand and presence-at-hand, and his analysis of everyday inauthenticity in the structures of idle talk, curiosity, and ambiguity. The study then explores the decisive roles of anxiety, Being-toward-death, conscience, guilt, and resoluteness in opening the possibility of authentic existence. Care is presented as the structural unity of Dasein, whose ontological meaning is temporality—understood through the ecstases of future, past, and present. The article further addresses Heidegger's reinterpretation of truth as unconcealment, the project's incompleteness, and its transition to the later thinking on the history of Being and technology. It concludes by acknowledging both the work's enduring philosophical significance and its critical limitations—including the underdevelopment of the body, politics, ethics, and natality—while affirming that Being and Time remains an indispensable foundation for contemporary philosophy.
“Being and Time” is not an ordinary philosophical book one simply enters; entering it means entering a new language, a new conceptual apparatus, and a different way of questioning. Many philosophical works can be summarized to some degree by identifying their central problem, main concepts, and key arguments. But “Being and Time” resists summarization, because the book itself is an attempt to transform the very way we understand philosophy. In this work, Heidegger does not seek to offer a new theory about man, knowledge, the world, or ethics. Before all that, he wants to ask what the meaning of Being is, and why this question, despite its apparent obviousness, has been forgotten in the history of philosophy. The difficulty of the book arises precisely from this: “Being and Time” does not merely answer a new question; it tries to reorganize the very possibility of questioning itself.
Heidegger's starting point is both very simple and very fundamental. We constantly speak of "being." We say this table is, man is, the world is, God is or is not, truth is, possibility is, history is. But when we ask "what does 'being' mean?," we suddenly face a difficulty. Being is both the most obvious and the most obscure of concepts. Obvious, because we already employ it in every statement and every act of understanding; obscure, because precisely due to this obviousness, we rarely ask about its meaning. The Western metaphysical tradition, in Heidegger's view, has asked more about beings than about Being. Philosophy has spoken of beings “qua” beings, substance, cause, God, subject, spirit, nature, and will, but it has forgotten the very horizon in which beings appear “as” beings. “Being and Time” was written to break this oblivion.
But how should the question of Being be initiated? Can one ask directly about Being? Heidegger answers that to pose the question of Being, one must begin with a being that itself has an understanding of Being; a being that, in its very Being, has a relation to its own Being. This being is Dasein. In German, “Dasein” literally means "being-there," but in Heidegger it becomes a technical philosophical term. He does not use the word "man," because he does not want to start from a biological, psychological, ethical, or theological anthropology. In the philosophical tradition, man has usually been defined as the rational animal, the knowing subject, the soul, the person, the individual, or the social being. Heidegger wants to ask, prior to all these definitions, how the being about whom such definitions are possible is disclosed in its own Being. Dasein is the name for this disclosedness; the name for the being for whom Being is an issue.
From here, it becomes clear that “Being and Time” is not a book about man in the ordinary sense, but an existential analysis of Dasein. Heidegger calls this analysis "fundamental ontology," because its ultimate aim is not anthropology, but the preparation of the way for the question of the meaning of Being. Dasein is the subject of this analysis because it has a pre-philosophical understanding of Being. Prior to any theory, we already know how to deal with things, tools, others, possibilities, the future, death, and the world. This understanding is usually not explicit or theoretical, but it operates in our everyday lives. When we open a door, pick up a pen, speak with someone, wait for news, fear a danger, plan a task, or think about death, in all of these there is a kind of understanding of Being, possibility, world, self, and others. The analysis of Dasein means making this pre-theoretical understanding explicit.
Methodologically, “Being and Time” is based on phenomenology, but Heidegger's phenomenology goes beyond the Husserlian framework. Husserl understood phenomenology as a return to the things themselves and wanted to describe the structures of consciousness and intentionality. Heidegger accepts this legacy but transforms it in an ontological direction. The question is no longer merely how consciousness intends objects, but how beings become manifest for Dasein within the disclosedness of the world. Thus, phenomenology in “Being and Time” means the method of uncovering what has remained hidden in everyday experience—not because it is far away, but precisely because of its excessive proximity. Being is hidden, not because it lies somewhere distant, but because it is already present in all our understanding, and this very presence conceals it from view.
For this reason, Heidegger's phenomenology is hermeneutical from the start. Dasein is a being that always already finds itself and the world within an interpretation. We are never confronted with raw, meaningless data. The world is always already meaningful for us. The room, the table, the pen, the window, the street, the house, the university, the friend, the enemy, work, the future, and the past all appear within a network of meaning. This meaning is not something the mind adds to things after encountering them; it is the very way Dasein is in the world. Hence, understanding, interpretation, and meaning are not secondary structures of cognition; they are more fundamental than theory and science. Man does not first interpret the world in a conscious, theoretical sense, but in the sense of living within a horizon of use, possibility, language, tradition, and expectation.
One of the most important innovations of “Being and Time” is the break with the Cartesian model of subject and object. In modern philosophy, the problem is often framed as follows: there is a conscious subject who stands over against an external world, and one must explain how this subject can attain knowledge of objects. Heidegger argues that this way of posing the problem is misguided from the start, because man is never in the first instance a subject separated from the world. Dasein is always “in-the-world”. “Being-in-the-world” (“In-der-Welt-sein”) is one of the most fundamental concepts of the book. This expression should not be understood as the spatial containment of one thing inside another, like water in a glass or a book on a shelf. Dasein is “in” the world, meaning the world is the meaningful horizon within which Dasein's Being always occurs. Dasein and the world are not two separate things that are later connected; Dasein is from the start worldly.
"World" here does not mean the totality of objects existing in space. World, for Heidegger, is a network of significance, reference, possibility, and use. For example, when we enter a room, we are not first confronted with a collection of meaningless objects that we then interpret. The table appears as something for writing, the chair as something for sitting, the lamp as something for lighting, the book as something for reading, the door as a way in and out, the window as an opening to the outside. All of these appear from the start within a network of functions and references. We do not first know the world theoretically; we work in it, move in it, live in it, and pursue our possibilities within it. Thus, the worldhood of the world is prior to scientific and theoretical knowledge.
The General Structure of the Book and Heidegger's Hermeneutical Phenomenology
To understand “Being and Time”, before delving into concepts like Dasein, worldhood, falling, care, death, conscience, and temporality, one must grasp the book's overall structure and its method. “Being and Time” is not a book that can be read like a linear, classical treatise—one that begins with a few definitions, then arranges some logical premises, proceeds with orderly arguments, and ends with a definitive conclusion. In this work, Heidegger engages with the traditional form of philosophy itself. He wants to revive a question that, in his view, has been forgotten in the history of philosophy, and for this reason, he cannot simply proceed with the language and method of that same tradition. The difficulty of “Being and Time” arises not only from its complex terminology, but from the fact that the book attempts to create a new way of questioning, seeing, and describing. If the reader expects from the outset a ready-made apparatus of definitions, they will quickly become lost in the text. “Being and Time” must be read as a gradual movement; a movement from the obviousness of everyday life toward the hidden structures of Dasein's Being, and from there toward the horizon of temporality and the question of the meaning of Being.
The announced structure of the book is larger than what was realized in the published version. In his original plan, Heidegger intended to pursue a more expansive project. The first part was to present an interpretation of Dasein on the basis of temporality and an explanation of time as the horizon for the understanding of Being. The second part was to carry out a phenomenological destruction of the history of ontology, following the path from Kant to Descartes and Aristotle. But the published book contains only a part of this plan, and even that remains unfinished. This incompleteness is one of the essential characteristics of “Being and Time”. From the outset, the book promises to clarify the question of the meaning of Being through the analysis of Dasein and temporality, but at the end, the full transition from the temporality of Dasein to the meaning of Being itself, as announced, is not carried out. Nevertheless, this incompleteness has not diminished the work's significance; on the contrary, part of its power lies in this state of being on the threshold. “Being and Time” opens a path that it cannot itself complete, but it compels philosophy after it to think either along that path or in opposition to it.
The book begins with an introduction in which Heidegger raises the necessity of repeating the question of Being. He says the question of Being is forgotten today, not because no one uses the word "Being," but because everyone assumes its meaning is clear. Being, in the common view, is considered the most universal, the most obvious, and the most indefinable of concepts. It is the most universal because it is said of everything; it is the most obvious because we already understand it in every statement; it is indefinable because it cannot be defined by a more universal concept. But Heidegger shows that these three characteristics are not reasons for not asking the question, but precisely reasons for its necessity. If Being is the most universal, it should not be confused with the most general logical genus. If it is the most obvious, this very obviousness requires clarification. If it is indefinable, this does not mean it is unworthy of question, but rather that we must find a different way of questioning. Philosophy, for Heidegger, begins precisely where the most obvious thing becomes questionable again.
The question of Being, like any question, has three components: what is asked about (“das Gefragte”), what is interrogated (“das Befragte”), and what is sought in the question (“das Erfragte”). Here, what is asked about is Being itself; what is sought is the meaning of Being; but the being that must be interrogated is Dasein. Why Dasein? Because Dasein is the only being that, in its Being, has an understanding of Being. A stone is, a tree is, an animal is, a tool is, a number is, but none of these questions its own Being. Dasein is the being for whom, in its Being, Being is an issue. It already has, even before philosophy, a kind of understanding of Being. Of course, this understanding is usually vague, everyday, and non-theoretical, but this vague understanding is the condition for the possibility of any philosophical questioning. If Dasein had no understanding of Being, the question of Being would have no meaning for it. Thus, the analysis of Dasein is the way into the question of Being, not its final destination.
Here, an important misunderstanding must be set aside. “Being and Time” is not a book about man in the sense of anthropology. Heidegger does not address human psychology, sociology, biology, or ethics, though his analysis has implications for all these fields. Dasein is not simply equivalent to "man." Dasein is the name for man from a specific aspect: from the aspect that he stands in the disclosedness of Being and understands his own Being. Thus, the analysis of Dasein is an existential analysis, not an ontical one—not an examination of the properties of a particular being alongside other beings. Heidegger distinguishes between the “ontical” and the “ontological”. The ontical pertains to the properties, states, and realities of beings; for example, what biological structure a human has, what society they live in, what psychological traits they have, or what behaviors they exhibit. The ontological pertains to the Being of beings; that is, to the horizon in which something appears “as” something. The analysis of Dasein in “Being and Time” is ontological, because it seeks to uncover the structures of Dasein's Being, not to compile a set of empirical data about man.
The method of such an analysis is phenomenology, but phenomenology in Heidegger's sense requires explanation. Heidegger understands the word "phenomenology" from its two Greek components: “phainomenon” and “logos”. A phenomenon is what shows itself; but the crucial point is that what shows itself can at the same time conceal itself. Phenomenology is not merely the description of what is manifest; it is the uncovering of what has remained hidden within this very manifestness. Being is such a thing. Beings show themselves, but their Being—the disclosedness in which beings become manifest—usually remains hidden. Thus, phenomenology means letting what shows itself be seen from itself in the very way in which it shows itself. This method seems simple in principle, but in practice it is difficult, because we always approach phenomena with prejudices, traditional concepts, established languages, and theoretical habits. Phenomenology must set these coverings aside.
But Heidegger's phenomenology is hermeneutical from the start. This means that the uncovering of phenomena always occurs through understanding and interpretation. Dasein is a being that always already finds itself and the world within a historical and linguistic understanding. It never begins from point zero. Every understanding rests on a pre-understanding. Every interpretation arises from a prior horizon of meaning, possibility, language, and tradition. Thus, phenomenology cannot consider itself a pure, presuppositionless, completely ahistorical observation. Unlike the ideal of certain forms of phenomenology that sought to return to pure data of consciousness, Heidegger shows that Dasein always lives in an already interpreted world. We do not first receive the world as raw data and then give it meaning; the world is meaningful from the start. Hermeneutics means the analysis of this structure of prior understanding and the interpretability of Dasein.
For this reason, “Being and Time” deals with a kind of hermeneutical circle. To understand Being, one must analyze Dasein, but to analyze Dasein, one already needs an understanding of Being. This circle, for Heidegger, is not a defect of the method; it is the structure of understanding itself. Every understanding already understands something and then clarifies that pre-understanding. The problem is not to escape the hermeneutical circle, but to enter it correctly. Authentic understanding means becoming aware of one's presuppositions, uncovering hidden horizons, and moving from vague understanding toward clearer understanding. “Being and Time” is precisely such a movement: it begins with Dasein's everyday and vague understanding of Being and seeks to uncover the hidden structures of this understanding. Thus, the hermeneutical circle in the book is the engine of thought, not an obstacle to it.
In this method, the description of everydayness plays a decisive role. Heidegger does not begin his analysis from exceptional experiences, mystical states, scientific theories, or abstract situations. He begins from Dasein's everyday life: from work, tools, language, being-with-others, idle talk, curiosity, fear, concern, and the ordinary world. Why? Because the fundamental structures of Dasein show themselves in this very everydayness, albeit in a concealed way. Traditional philosophy often considered everyday life superficial, inferior, or unphilosophical, and sought truth in theory, reflection, reason, or the universal. Heidegger, on the contrary, shows that everydayness is the primary field of Dasein's disclosedness. We first live in the everyday world, and it is only on the basis of this world that science, theory, ethics, and philosophy become possible. Thus, the analysis of everydayness is not a fall from philosophy, but the way into the hidden foundations of philosophy.
This attention to everydayness separates Heidegger from the philosophy of consciousness. In the philosophy of consciousness, man is often considered as a subject standing over against objects. The main problem is how this subject can know the external world. Heidegger considers this picture secondary and derivative. Dasein, before it is a knowing subject, lives in a world that is already disclosed for it. Its relation to the world is not primarily theoretical, but practical, affective, linguistic, and historical. We do not first look at things and then decide what use they have; they appear from the start in use, reference, and meaning. In the simplest actions—like opening a door, writing, driving, eating, or speaking—the world is understood as a network of possibilities and references. Thus, theoretical knowledge is possible on the basis of Being-in-the-world, not the other way around.
“Being-in-the-world” is the fundamental structure of Dasein, and the entire first part of “Being and Time” revolves around the explanation of this structure. This concept has three intertwined dimensions: the world, the being that is in the world, and the way of Being-in. But these three should not be understood separately and then connected. Dasein and the world are from the start in a structural unity. The world is the meaningful horizon of Dasein, and Dasein is the being that always stands within this horizon. Being-in also does not mean spatial containment; it means being familiar with, being involved in, dwelling in, and living within a network of meaning. Just as we say someone lives in the Persian language, or in a tradition, a city, a family, or a world of thought, Dasein is “in” the world. This "in" has an existential, not merely spatial, meaning.
In the analysis of the world, equipment (“Zeug”) has a special place. Heidegger shows that our everyday world is constituted not primarily by present objects, but by equipment that is ready-to-hand (“zuhanden”). Readiness-to-hand means that something is understood in its use, in its relation to work and possibility. The hammer, the pen, the table, the shoe, the phone, the key, the book, and the street do not first appear as objects with physical properties, but as things for hammering, writing, sitting, walking, calling, opening, reading, and going. These "for-which"s constitute the referential structure of the world. Equipment is never alone; each piece of equipment refers to other equipment, tasks, goals, roles, and Dasein's possibilities. Thus, the analysis of equipment is a way of showing how the world is disclosed prior to theory.
When equipment breaks, gets lost, or becomes an obstacle, its worldhood becomes more apparent. As long as the hammer works properly, we do not attend to the hammer itself; our attention is on the work we are doing. But if the handle breaks, suddenly the hammer emerges from the invisible network of use and becomes something present and problematic. This moment shows that the theoretical presence of things is not the primary mode, but arises from a disturbance in readiness-to-hand. Science and theory also rely to some extent on such a shift: the world is detached from the network of everyday use and transformed into a collection of observable, measurable, and analyzable objects. Heidegger does not intend to devalue science with this analysis; he wants to show that science is based on a more fundamental way of Being-in-the-world. Theoretical knowledge is derived from practical engagement.
Alongside the world of equipment, the world of others is also present from the start. Being-with (“Mitsein”) shows that Dasein is never an isolated individual. Even when I am alone, my world is a world built with others. I have taken language from others, tools are for public use, houses, streets, roles, and customs are all social. The other need not always be personally present; the other is present in the very structure of the world. A classroom, a train station, a book, a law, or a piece of clothing all belong from the start to a shared world. Dasein is always in this shared world. Thus, the problem of the existence of other minds, as posed in modern philosophy, is for Heidegger a secondary problem. We are first with others; only later might we question the knowledge of another's mind.
But this Being-with takes a specific form in everydayness: the dominance of “das Man”, the "they." The "they" are not any specific person nor a definite group; they are the invisible force of publicness that determines what is normal, correct, acceptable, important, unimportant, beautiful, ugly, successful, or failed. In everyday life, Dasein usually does not ask what its authentic possibility is; it thinks, speaks, and lives as the "they" think, speak, and live. This situation is comforting on one hand, because it lightens individual responsibility; on the other hand, it alienates Dasein from itself. The "they" have already interpreted everything. They have even turned death into a public event: "people" die, death is for everyone, but "I" do not encounter death as my own distinctive possibility. Authenticity becomes possible precisely through a rupture from this public cover.
Heidegger's method here is neither a moralization of everydayness nor a praise of heroic individualism. He does not say the "they" are bad and authentic Dasein must flee from society. He says that in its everyday structure, Dasein tends toward falling; that is, it becomes absorbed in the public world and alienated from its own distinctive possibility. This falling is part of Dasein's Being. Thus, authenticity does not mean a complete exit from everydayness, but a different way of Being in the same world. Authentic Dasein still lives with equipment, others, language, and society, but it does not completely surrender itself to the public interpretation. It takes over its own possibility. This taking-over becomes possible through experiences like anxiety, the call of conscience, and the confrontation with death—experiences that play a decisive role in the later parts of the book.
One of the important features of Heidegger's method is that it moves from the analysis of ordinary structures toward more fundamental structures. He first analyzes Dasein in its average everydayness, then shows that this everydayness is grounded in a deeper structure, namely care (“Sorge”). Care is the existential unity of Dasein. Dasein is always ahead of itself, because it has possibilities; it is always already thrown into a world, because it did not choose its beginning; and it is always engaged with beings and others. These three dimensions are unified in care. Care shows that Dasein is not a being that first exists and then sometimes cares about things; Dasein's Being itself is caring, being involved, and having a relation to its own Being. Dasein cannot cut off its relation to its Being. Even fleeing from oneself is a form of relating to oneself.
This movement from everydayness to care, and then from care to temporality, constitutes the main architecture of “Being and Time”. Heidegger wants to show that the ultimate structure of care is temporal. Dasein, because it is futural, can understand its possibilities; because it is past-oriented, it stands in thrownness and heritage; because it is present, it deals with beings in the world. Time here is no longer a container in which events occur; it is the horizon of Dasein's self-understanding. Thus, the title “Being and Time” points precisely to this path: the question of Being, through the analysis of Dasein, leads to time. If Dasein is the horizon for the understanding of Being, and if Dasein's structure is at bottom temporal, then time must be the horizon for the understanding of Being. This is the great thesis of the book, even though its full realization remains incomplete.
The incompleteness of the project must be understood in relation to the difficulty of this transition. Heidegger was able to show that Dasein is temporal and that the understanding of Being in Dasein is related to time. But the transition from the temporality of Dasein to the meaning of Being itself was not fully carried out. Later, Heidegger himself took a different path and, instead of continuing directly with the project of “Being and Time”, turned to the history of Being, the event, language, technology, and the later thinking. But this change of direction should not be seen as a simple failure of “Being and Time”. Perhaps the difficulty of the question itself led Heidegger to realize that the analysis of Dasein, while necessary, is not sufficient. One must also ask about the history of the disclosedness of Being itself. Nevertheless, “Being and Time” remains the point of departure; without it, the later Heidegger is unintelligible.
To read “Being and Time”, one must also attend to the language of the book. Heidegger deliberately alters or newly constructs common philosophical vocabulary. Dasein, readiness-to-hand, presence-at-hand, Being-in-the-world, Being-with, the "they," care, attunement, understanding, falling, guilt, resoluteness, and temporality—all these terms must be understood within their conceptual network. Translating these words into other languages, including English, is always difficult. For example, “Sein” can be translated as "Being" or "Existence," and “Sein und Zeit” has been rendered as “Being and Time”. Each choice has consequences. "Being" sometimes has a more general and nominal sense; "Existence" carries a different weight. No translation is without problems. What matters is that the reader understands that Heidegger does not speak of “Sein” as a being, substance, or universal concept, but asks about the disclosedness of the Being of beings.
One must also note that “Being and Time” cannot be read quickly. The book requires pauses, because many of its concepts are not clear at the start and only find their place as one proceeds. For example, Being-in-the-world cannot be fully understood without the analysis of equipment and the "they"; care is not clarified without anxiety and falling; temporality is not fully grasped without death, conscience, and resoluteness. Thus, reading the book must be circular: the initial understanding of concepts helps one continue reading, and the reading further clarifies the meaning of the initial concepts. This is the hermeneutical circle in practice. “Being and Time” is a book one must return to again and again, because its beginning only acquires its meaning after one has traversed the path of the book.
In terms of its historical position, “Being and Time” stands at the intersection of several traditions: Husserl's phenomenology, Dilthey's hermeneutics, the philosophy of life, early Christian theology, Aristotle, Kant, Kierkegaard, Nietzsche, and the critique of modern philosophy. But Heidegger does not simply continue any of them. From Husserl, he takes the phenomenological method, but transfers it from consciousness to Being. From Dilthey, he learns about historicity and the understanding of life, but reconstructs it at the ontological level. From Aristotle, he draws inspiration for the analysis of practice, “phronesis”, and Being-in-the-world, but cultivates it in a new language. From Kierkegaard, he takes anxiety, individuality, and decision, but translates them from theology into ontology. From Kant, he takes seriously the problem of time and finitude, but links it to the analysis of Dasein. “Being and Time” is the product of these heritages, but ultimately becomes an independent project.
At the end of this section, one can say that the method and structure of “Being and Time” can be summarized as follows: the main question is the meaning of Being; the way in is the analysis of Dasein; the method is hermeneutical phenomenology; the initial field of analysis is Dasein's average everydayness; the fundamental structure of Dasein is Being-in-the-world; the unity of this structure is care; and the ultimate horizon of care is temporality. All the concepts of the book acquire meaning in relation to this architecture. If this architecture is not seen, “Being and Time” appears as a collection of difficult terms. But if it is seen, the book appears as a coherent attempt to reopen the question of Being. Its difficulty arises not from disorder, but from the depth of the problem it seeks to approach: what the meaning of Being is, and why man, this temporal and caring being, holds a privileged place in posing this question.
Dasein: Why Does Heidegger Speak of Dasein Instead of Man?
One of the first difficulties in reading “Being and Time” is encountering the word “Dasein”. The reader may initially ask why Heidegger does not simply speak of "man." If the subject of his analysis is precisely this being that we are, who lives, thinks, dies, relates to others, and acts in the world, then why use a complex and unfamiliar term? The answer to this question leads to the heart of the project of “Being and Time”. Heidegger does not begin with "man" because the word "man" in the history of philosophy, theology, psychology, biology, and the human sciences has already acquired numerous layers of meaning. Man has been understood as the rational animal, the knowing subject, the soul, the person, the moral agent, the social being, the evolved living being, the free individual, or the rational agent. Each of these definitions shows part of the truth about man, but for Heidegger, all of them overlook a more fundamental question: the being about whom such definitions are possible, how is it primordially disclosed in its Being?
“Dasein” is the name for this fundamental question. In ordinary German usage, “Dasein” can mean "existence" or "presence," but Heidegger employs it in a specific and technical sense. “Da” means "there" and “Sein” means "being." Thus, “Dasein” can be roughly understood as "being-there" or "being-in-disclosedness." But these translations are only guidelines and should not be taken as exhausting the meaning of “Dasein”. Dasein is the being that is the "there" of the disclosedness of Being; that is, the being in and for whom beings can become manifest as beings. Dasein is not merely a being among beings; it is the being that has an understanding of its own Being and the Being of other beings. This understanding may be vague, unconscious, and everyday, but in any case, Dasein cannot live without some kind of understanding of Being.
The importance of Dasein arises from this relation to Being. A stone is, but its Being is not an issue for it. A tree is, grows, takes root, and dies, but does not ask about its own Being. Animals have complex perceptual and behavioral worlds, but for Heidegger, they do not pose the question of Being in the strict sense. Man, or Dasein, is the being for whom, in its Being, Being is an issue. He can ask: who am I, what should I do, why is there something, what is the meaning of my death, what is the world, what is truth, and how should I live? Even when he does not pose these questions explicitly, his life relies on an implicit understanding of them. Dasein means the being for whom its Being is not a matter of indifference. This non-indifference, this involvement with one's own Being, is the foundation of all the analyses in “Being and Time”.
To explain Dasein, Heidegger uses the term “Existenz”, but he does not employ it in its ordinary sense. Existing is true of many beings; a table exists, a tree exists, an animal exists. But “Existenz” for Heidegger refers to the specific way of Being of Dasein. Dasein does not merely "exist"; it must “be” its Being in a certain way. That is, Dasein is always dealing with its possibilities. It is not something fixed and complete that merely has a set of properties. Being human means always being in relation to possibilities: the possibility of working, choosing, fleeing, understanding, failing, losing oneself, recovering oneself, living with others, confronting death, and taking over or not taking over oneself. Dasein is what it is, but what it is, is open to its possibilities. It is a possible being, not in the sense of a fictional being, but in the sense of a being whose Being is always lived in the mode of possibility.
For this reason, Heidegger says that the “essence” of Dasein lies in its existence. If this statement is not understood carefully, it may be conflated with later existentialist slogans, such as the priority of existence over essence. But Heidegger has a specific meaning. He does not mean to say that man first exists without any determination and then constructs his own essence. His point is that Dasein cannot be understood like an object with an essential definition. The essence of a table can be explained by its function, shape, or material. The essence of a natural object can be examined by its structure and laws. But Dasein is a being whose Being is in each case entrusted to itself. Dasein is what it has to be, and it must take over its Being, consciously or unconsciously, authentically or inauthentically. Thus, Dasein's essence lies not in a fixed definition, but in the way it exists.
This point is expressed in another way in “Being and Time”: Dasein is in each case “mine” (“Jemeinigkeit”). Dasein is always "mine," not in the sense of private ownership or psychological individualism, but in the sense that no one can be my Being in my place. I can follow others, lose myself in the "they," surrender my responsibility to custom, family, society, party, tradition, or fashion, but even this flight is a way in which I myself live my Being. My Being is entrusted to me. Another can help me, deceive me, guide me, or influence me, but cannot die in my place, be authentic in my place, or take over my distinctive possibility in my place. Dasein is Dasein because in each case its Being is its own issue.
But this "mineness" should not be confused with abstract individualism. Heidegger does not regard Dasein as an isolated individual, a self-grounding subject, or a detached consciousness. Dasein is from the start in the world and with others. It takes its language, tradition, body, history, family, society, tools, places, and possibilities from a world that existed before it. Thus, Dasein is always both mine and already thrown into a shared world. I take over my Being, but I do not begin this Being from nothing. I am born into a language, placed in a history, live with a particular body, raised in a culture, move within a system of possibilities and limitations, and find meaning in a world with others. Dasein always stands between selfhood and worldliness. Its authenticity lies not in exiting the world, but in a different way of Being in this same world.
One of the main reasons Heidegger uses the term “Dasein” is to distance himself from the traditional definition of man as the rational animal. The definition of man as “animal rationale”, or rational animal, appears to elevate man above the animal, but for Heidegger, this very definition begins with the animal and then adds reason as a distinctive attribute. In this definition, man is first understood as a living being, and then reason, language, or thought is added to him. But Heidegger believes that this way of proceeding conceals man's fundamental relation to Being. Man is not merely an animal with more reason; Dasein is a being for whom the world is disclosed and who lives within the horizon of Being. Reason, language, action, ethics, science, and religion are all possible on the basis of this disclosedness. Thus, Dasein is a concept that seeks to understand man prior to anthropological and metaphysical definitions.
Heidegger also does not want to begin with the "subject." In modern philosophy, the subject usually means the center of consciousness, knowledge, will, or representation. From Descartes onward, the main problem of philosophy often became how the subject gains access to the external world. Heidegger considers this problem secondary. Dasein is from the start in the world; it does not need to build a bridge from inside the mind to the outside world. The world is already disclosed for it. I am first in a room, a house, a city, a language, a job, a family, and a history; only then might I construct a theory about the relation between mind and world. The Cartesian subject is a being that seems to be present in itself first and then relates to the world. But Dasein is from the start outside itself, with the world, among others, and in its possibilities. It is not trapped inside the mind nor a spectator of the world; it is engaged with the world.
From here, one can understand why Heidegger's analysis of Dasein begins not with knowledge, but with everyday life. If man is considered a subject, it is natural to take knowledge, consciousness, and theoretical perception as the starting point. But if man is considered Dasein, the starting point must be Being-in-the-world. Dasein does not first observe the world; it works in the world, walks, speaks, uses tools, fears something, waits for something, lives with others, sinks into habits, and pursues its possibilities. Thus, the analysis of Dasein must begin where Dasein usually is: everydayness. This methodological decision is very important. Heidegger does not seek the truth of man in exceptional or theoretical states; he uncovers Dasein's fundamental structures in ordinary, average life.
In everyday life, Dasein usually understands itself through the world. I understand myself through my work, my roles, my social relations, my successes and failures, the available possibilities, the judgments of others, and public language. If one asks someone "who are you?," the answers often come from the public world: job, family, education, social status, nationality, beliefs, interests, and roles. These answers are not wrong, but they show Dasein at an everyday level. Heidegger wants to show that behind these everyday definitions, there is a deeper structure. Dasein is a being that understands itself from its possibilities. It is always more than what it is actually now, because it is open to future possibilities. I am not just what I have done; what I can become, what I flee from, what I take over, and what I lose also belong to my Being.
This possibility is accompanied by thrownness (“Geworfenheit”). Dasein does not freely choose its possibilities from nothing. It finds itself in a world that has already begun. No one has chosen their language, family, time of birth, initial body, early culture, history, and many of their fundamental conditions. We are “thrown” into the world. Thrownness does not mean that man has fallen into the world like a helpless stone. Rather, it means that Dasein's freedom always occurs within givenness, limitation, heritage, and facticity. I have possibilities, but my possibilities are always opened within a specific world, with a specific past, a specific body, specific possibilities, and specific limitations. Dasein is both freedom and facticity; both projection and thrownness.
This duality appears in the concept of understanding. Understanding (“Verstehen”) for Heidegger is not merely a mental activity or theoretical knowledge. Understanding means the ability to be in possibilities. Dasein understands the world and itself through the possibilities that are opened before it. When I say someone "understands their work," I do not just mean they know propositions about that work; they can move in that field, see possibilities, use tools, recognize situations, and find themselves in that world. Understanding is always practical, existential, and possible. Because Dasein has understanding, it can project itself toward the future. This projection (“Entwurf”) does not always mean conscious planning; it is the fundamental structure of Dasein's Being. Dasein is always projected toward possibilities, even if these possibilities are taken from the "they."
Alongside understanding, attunement (“Befindlichkeit”) is another fundamental structure of Dasein. Dasein is never neutrally and dispassionately in the world. It always finds itself in a mood: fear, boredom, joy, anxiety, calm, heaviness, hope, restlessness, or indifference. Attunement shows us that Dasein, prior to any theory, has already found itself in the world. The world is always disclosed to us with a particular tonality. A room does not appear the same in joy and in sorrow; the future is not the same in hope and in anxiety; solitude does not have the same meaning in calm and in fear. Attunement shows that Dasein is not merely rational understanding; it is disclosed in the world in an affective way. This affect is not superficial psychology, but a way in which the world acquires meaning for Dasein.
Understanding and attunement are expressed in discourse (“Rede”). Discourse for Heidegger is the foundation of language, not merely verbal speech. Because Dasein is understanding and attuned in the world, it can express, articulate, conceal, or distort meanings. Language is not just a tool for transmitting information; it is one of the structures of Dasein's disclosedness. In language, the world is articulated. But this same language in everyday life can fall into idle talk (“Gerede”), that is, the repetition of ready-made meanings, without Dasein having authentically encountered the things themselves. Thus, Dasein is always in danger of taking its understanding from public language and the "they," and no longer seeing itself. This danger is part of Dasein's structure, because Dasein always lives in a shared world and a shared language.
From these structures, the distinction between authenticity and inauthenticity emerges. Inauthenticity for Heidegger does not mean a sinful, worthless, or morally inferior life. Inauthentic Dasein is Dasein that understands itself entirely from the public world and the "they," and does not take over its own distinctive possibility. Authenticity also does not mean heroic self-sufficiency or separation from others. Authentic Dasein is one who understands that its Being is entrusted to it, that its death is its own distinctive possibility, and that it cannot completely surrender the responsibility for its Being to the "they." Authenticity is a way of Being in which Dasein extricates itself from complete absorption in everydayness and takes over its own possibility. But this taking-over occurs in the same world, not outside it.
Here one must beware of simple psychological or ethical readings. Heidegger does not mean to say that man should find his "true self" in the popular psychological sense. Nor does he say one should become an individual independent of society and tradition. His problem is deeper. In inauthenticity, Dasein takes itself from public possibilities and flees from confronting its own finitude. In authenticity, it understands that no one can be its Being in its place. This understanding is connected to anxiety, death, conscience, and resoluteness—concepts that will be examined in detail later. Thus, Dasein has from the start two fundamental possibilities: to lose itself in the "they" or to return to its own distinctive possibility. Both possibilities belong to its structure of Being.
Another important point is that Dasein is always temporal. Even before Heidegger reaches temporality in the second part of the book, the concept of Dasein is from the start temporal. Dasein understands itself from the future, because it lives with possibilities. It comes from the past, because it is thrown and has a heritage. It is engaged in the present with the world, because tools, others, and everyday tasks occupy it. Thus, Dasein is not something present and fixed; it is a temporal pull. Being human means always being ahead of oneself, while coming from a past and being engaged in a present. This temporal structure will later be explained more precisely in the concepts of care and temporality. But from the start, one must know that Dasein cannot be understood without time.
This temporality is linked to death. Dasein is a being that understands its end in a certain way. Of course, all living beings die, but Dasein is “toward” death, meaning death is a possibility for it; a possibility that limits, makes serious, and individualizes all other possibilities. Death, in “Being and Time”, is not merely a biological event; it is an existential structure. When Dasein confronts its own death, not the public death of the "they," it understands that its Being is not transferable. No one can experience my death in my place. Thus, death extricates Dasein from absorption in the "they" and opens the possibility of authenticity. But this discussion must be examined separately later. In this section, it is only necessary to see that the concept of Dasein itself is from the start linked to possibility, finitude, and time.
Now one can say that Dasein is a concept designed to escape several reductions. First, the reduction of man to an object or a present-at-hand being. Dasein is not like a table or a stone that merely has properties. Second, the reduction of man to a knowing subject. Dasein is in the world prior to theoretical knowledge. Third, the reduction of man to a rational animal. Dasein is understood through its relation to Being, not by adding reason to life. Fourth, the reduction of man to a psychological individual. Dasein is from the start with others, language, history, and the shared world. Fifth, the reduction of man to a product of society. Dasein, though in the public world, is in each case its own Being. Sixth, the reduction of man to a completely free, self-making being. Dasein is free, but in thrownness and facticity. This escape from reductions is what makes the concept of Dasein necessary.
From this perspective, Dasein is one of the most important concepts of twentieth-century philosophy, because it fundamentally transforms the image of man. After Heidegger, it is difficult to regard man merely as mind, body, soul, subject, animal, individual, citizen, worker, consumer, or rational agent. All these can be aspects of man, but prior to them, man is Dasein: disclosedness, possibility, thrownness, understanding, attunement, Being-with, language, falling, care, and temporality. Dasein is not the final definition of man, nor a replacement for all the human sciences; rather, it is the ontological horizon on the basis of which one can understand why man can also be the subject of psychology, sociology, ethics, politics, theology, and science. Dasein is the condition for the possibility of these understandings, not a simple rival to them.
At the same time, one must also note the limitations of the concept of Dasein. By choosing this term, Heidegger was able to escape many metaphysical reductions, but sometimes his Dasein appears too abstract. The body, gender, class, race, illness, childhood, old age, disability, and many other concrete dimensions of human life are underrepresented in his analysis. Dasein is in the world, but to what extent is this world shaped by power, economy, gender, and social history? Dasein is bodily, but the body is analyzed less in “Being and Time” than worldhood and temporality. Dasein is with others, but the other as an ethical and vulnerable face is not placed at the center. Thus, the concept of Dasein must both be preserved and supplemented. Its power lies in opening the existential horizon of man; its limitation lies in its relative inattention to certain bodily, social, and political realities of human existence.
Nevertheless, without understanding Dasein, one cannot understand “Being and Time”. All subsequent concepts refer back to this concept. The worldhood of the world is the world of Dasein. Readiness-to-hand and presence-at-hand are modes in which beings appear for Dasein. The "they" and falling are the everyday way Dasein is with others. Anxiety is the mood in which the everyday world loses its validity for Dasein. Death is Dasein's distinctive and non-transferable possibility. Conscience is the call of Dasein to its own possibility. Care is the structural unity of Dasein's Being. Temporality is the ultimate horizon of this unity. Thus, Dasein is not one concept among others in the book; it is the center of the architecture of “Being and Time”. Heidegger begins with Dasein because only through this being can the question of Being be revived.
In conclusion, one can say that Dasein is the name for man, but not man as the sciences, traditions, and metaphysics have already defined him; Dasein is the name for man from the aspect of his disclosedness to Being. Dasein is a being that lives in the world, is with others, understands its possibilities, finds itself in a mood, belongs to language, falls in everydayness, is limited by death, is called by conscience, and lives its Being in temporality. This image of man is both profound and liberating, as well as difficult and incomplete. Profound, because it frees man from the captivity of the image of subject and object. Liberating, because it shows that human Being is always possibility. Difficult, because it does not remove the responsibility of Being from man's shoulders. Incomplete, because it still needs to be supplemented by body, ethics, politics, and the other. But this incompleteness is also part of its power: Dasein is an open question, not a closed answer. Man, in Heidegger's deepest sense, is a being who can never be reduced to a final definition, because his Being is always opened within the horizon of possibility, time, and the question of Being.
Being-in-the-World and Worldhood: Moving Beyond Subject and Object
If we were to summarize one of the most important innovations of “Being and Time” in a single phrase, we would have to speak of the concept of “being-in-the-world” (“In-der-Welt-sein”). This concept is the core of Heidegger's analysis of Dasein, and without understanding it, almost all the other concepts of the book remain obscure. Dasein is not a being that is first present in itself, in the mind, in consciousness, or within its own psyche, and then attempts to find a way to an external world. Dasein is from the start “in” the world. But this "in" should not be understood in a spatial or physical sense, as if Dasein were something placed inside a container called the world. Being-in-the-world means that Dasein always lives within a horizon of meaning, possibility, equipment, relation, language, history, and others. The world is not something later added to Dasein; the world is a structure of Dasein's very Being.
This statement stands against one of the most deeply rooted pictures in modern philosophy: the picture of subject and object. In this picture, man or the mind is assumed as an inner, conscious subject that stands over against an external world of objects. The main problem of philosophy then becomes how this subject can reach outside itself, how it can know objects, how it can be certain of the correspondence between thought and reality, and how the gap between mind and world can be bridged. Heidegger fundamentally overturns this way of posing the problem. He does not say there is an inner subject that must be connected to the external world; he says such a subject is itself a derivative abstraction. Prior to any separation between mind and world, Dasein is “in” the world, deals with the world, acts in the world, understands the world, and takes its possibilities from the world.
In other words, man's primary relation to the world is not theoretical knowledge. We do not first experience the world as a collection of objects present before the mind. Prior to any theory, prior to any science, prior to any neutral observation, we “live” in the world. We open a door, walk, talk with others, pick something up, do a task, wait for someone, avoid a danger, dwell in a house, orient ourselves in a city, and speak a language. These ordinary experiences are not superficial or unphilosophical; it is precisely in these everyday experiences that the fundamental structure of Being-in-the-world reveals itself. If philosophy wants to understand man, it should not begin from isolated consciousness; it should begin from this engaged, practical, meaningful, and worldly Being.
"World," in Heidegger's terminology, does not mean the totality of beings. When we say "world," we usually think of the totality of objects, nature, the cosmos, society, or the surrounding environment. But world in “Being and Time” has an ontological meaning. World is the meaningful horizon in which beings become manifest for Dasein as things to be used, understood, feared, expected, loved, built, or questioned. World, prior to being a collection of objects, is a network of references and possibilities. A room is not merely a collection of walls, ceiling, floor, table, chair, lamp, and window. The room is a space for work, rest, conversation, study, waiting, solitude, or living. The objects in the room acquire meaning in relation to Dasein's tasks and possibilities. The table is for writing, the chair for sitting, the lamp for lighting, the book for reading, the door for entering and exiting, the window for seeing outside or letting in light. These "for-which"s constitute the structure of the world.
Thus, “worldhood” (“Weltlichkeit”) means precisely this referential and meaningful structure of the world. Worldhood is neither a property added to a collection of objects, nor something subjective that Dasein imposes on objects. Worldhood is the structure of disclosedness in which things from the start appear in relation to one another and in relation to Dasein's possibilities. If we consider the hammer merely as a metallic and wooden object, we have not understood it in its worldhood. The hammer is in relation to the nail, the board, building, repair, house, work, and a specific purpose. The hammer is "for" hammering, hammering is "for" building, building is "for" dwelling, work, or satisfying a need, and all of these ultimately refer back to Dasein's possibilities. Thus, things in the world are not isolated points; they live in a network of references. The world “is” that network.
To demonstrate this point, Heidegger presents his famous analysis of equipment (“Zeug”). Equipment is something that is understood in its use. We do not first observe the hammer as an independent object with physical properties; we “work” with it. While working, the hammer is not the object of our theoretical attention. The hand, the hammer, the nail, the board, and the work all form part of a practical flow. The better the hammer works, the less it catches our eye. Its presence in the work has a kind of invisibility. We are engaged in the task being accomplished “through” the hammer, not in observing the hammer itself. This mode of appearance of equipment Heidegger calls “readiness-to-hand” (“Zuhandenheit”). Readiness-to-hand means that a thing appears in its availability for action, in its use, in its function, and in its network of references. This mode of appearance, for Heidegger, is more fundamental than theoretical, objective presence.
In contrast, “presence-at-hand” (“Vorhandenheit”) is the mode in which something appears as an object present before us. When the hammer breaks, it suddenly emerges from the natural flow of work. Now we no longer simply work with it; we look at it, examine it, consider its weight, shape, and material, and ask about the cause of its malfunction. At this moment, the hammer shifts from readiness-to-hand toward presence-at-hand. Of course, presence-at-hand is not bad, and science also relies to a large extent on this way of seeing. But the error of traditional philosophy and modern scientism is to suppose that presence-at-hand is the primary and fundamental mode of the appearance of things. Heidegger says the opposite: the theoretical object emerges from a disturbance in the practical, ready-to-hand world. We first “live” with things; only later do we make them objects of observation.
The importance of this analysis goes far beyond the example of the hammer. Through the analysis of equipment, Heidegger shows that man's relation to the world is at bottom practical, engaged, and contextual. A doctor in an operating room, a carpenter in a workshop, a driver on the road, a writer with a pen or keyboard, a cook in a kitchen, a musician with an instrument, or a farmer in a field does not first see the world as a collection of objects; rather, they move within a meaningful field of work. Tools, movements, habits, skills, and possibilities together form a network in which action becomes possible. Even when we are not consciously thinking about tools, a pre-understanding of the world is at work. This understanding is sedimented in the body, in habit, in language, in orientation, and in skill. Thus, worldhood operates prior to theory.
From here, one can understand why Heidegger considers the philosophy of consciousness inadequate. If we begin from theoretical consciousness, we see the world as a collection of data or objects and then try to add meaning, use, and relation to it. But in reality, meaning is already present in our experience from the start. A child, before being able to have a theory about objects, already lives in a world of faces, sounds, movements, things, and possibilities. An adult, in most moments of life, is not theorizing about the world; they are moving in it. When I pick up a key, I do not think of it as a metal object with a particular shape; I use it to open a door. When I walk up stairs, I do not observe each step as an independent object; my body knows the way. When I speak my mother tongue, I do not consciously recall grammatical rules; I “live” in the language. Worldhood is this pre-theoretical living in meaning.
But the world is not only the world of equipment; the world is always also a shared world. Equipment, tasks, and places are from the start related to others. The hammer was made by someone, the house is for someone's dwelling, the book was written for others to read, the street is for public passage, language comes from others, and social roles are formed in the shared world. Even if I am alone in a room, my world is not devoid of others. The chair, the book, the clothes, the clock, the phone, the house, the city, and the language all indicate that the world is from the start built with others. Thus, Being-in-the-world is always Being-with (“Mitsein”). Dasein is never first an isolated being that then enters into social relations. It is from the start in a world in which others also are.
This point also transforms the traditional problem of "the existence of other minds." In modern philosophy, if one begins from the isolated subject, one must explain how this subject can be certain that others also have minds. But Heidegger says such a problem is from the start ill-posed. The other is not first a physical object from whose behavior I then infer the existence of a mind. I am from the start in a world with others. Language, gesture, work, expectation, cooperation, shame, competition, care, and indifference all show that others are part of the structure of my world. Even solitude is only meaningful for a being who is fundamentally with others. If Being-with were not a fundamental structure of Dasein, solitude would not be possible. Thus, Dasein's worldhood is always social, though Heidegger analyzes this sociality not sociologically but ontologically.
In everyday life, this Being-with often appears in the guise of the dominance of the "they" (“das Man”). The "they" are the same indefinite public that has already interpreted the world. The "they" say what is important, what is unimportant, how one should live, what is valuable, how one should speak about death, what success is, and what failure is. In everydayness, Dasein usually understands itself through this public interpretation. This situation shows that worldhood concerns not only objects and equipment, but also social meanings. The everyday world is a world in which ready-made meanings circulate. We often see through the language of the "they" before we see for ourselves; we repeat public judgments before we judge for ourselves. Thus, the world can be both the possibility of understanding and the possibility of getting lost.
This duality is very important for Heidegger. The world is not merely a stage on which Dasein discloses itself; the world can also alienate Dasein from itself. Involvement with tasks, equipment, roles, others, talk, and everyday concerns can absorb Dasein so completely that it no longer confronts its own distinctive possibility. This absorption is “falling” (“Verfallen”). But falling does not mean exiting the world; it occurs precisely in the heart of the world. Dasein can get lost in the world because it is in the world. It can dissolve in the "they" because it is with others. It can fall into idle talk because it has language. It can take its understanding from ready-made meanings because it has understanding. Thus, worldhood is both the condition for the possibility of authenticity and the condition for the possibility of inauthenticity. Dasein cannot be itself outside the world; but in the world, it can also lose itself.
One of Heidegger's most subtle points is that worldhood should not be understood idealistically. When it is said that the world is a network of meaning, one should not think that the world is merely a construction of the human mind or consciousness. Heidegger is not a simple idealist. He does not say objects exist only in our minds. His problem is not whether the external world exists independently of us. He asks how the world as “world” is disclosed for Dasein. This question lies prior to the opposition between idealism and realism. Realism says objects exist independently of the mind; idealism says the world is in some way dependent on consciousness. Heidegger says both positions usually rely on the same subject-object gap. But Being-in-the-world is prior to this gap. Dasein is not trapped inside the mind nor merely set over against an external world; it is from the start in the disclosedness of the world.
On the other hand, worldhood should not be understood as arbitrary relativism. That the world is disclosed for Dasein within a horizon of meaning does not mean that Dasein imposes any meaning it wants on things. The world has its own structure, resistance, history, equipment, language, and possibilities from the start. The hammer cannot have just any meaning; it acquires meaning within a network of use, material, skill, and work. Language does not function arbitrarily; we speak a historical language that existed before us. Our body, the earth, death, others, tools, and institutions all have specific limitations and possibilities. Thus, worldhood is neither subjectivism nor relativism. The world is disclosed, but this disclosedness is structured, historical, and resistant.
This point is important in relation to science. Heidegger is not opposed to science; he wants to understand its proper place. Science is one way of disclosing beings, not the only way. Physics, biology, psychology, sociology, and history each make beings the object of study from a particular angle. But prior to any science, there is a world in which the scientific question acquires meaning. The scientist, before being a scientist, is Dasein; they live in a world, work with laboratory equipment, are trained in a scientific language and tradition, have goals, cooperate with others, and are interested in a particular truth. Science detaches the world from everyday readiness-to-hand and transforms it into an object of theoretical presence-at-hand. This is a powerful accomplishment, but if it forgets that it is itself possible on the basis of Being-in-the-world, it may absolutize itself.
Thus, Heidegger's critique of theory-centrism is not a denial of theory. Theory is one of Dasein's possibilities, but not its primary possibility. The scientific world emerges from the lived world. For example, nature, before it is the subject of physics, is the horizon of life, weather, light, darkness, danger, beauty, agriculture, walking, dwelling, and work. The body, before it is the subject of biology or medicine, is the lived body with which we walk, feel pain, touch, and experience the world. Language, before it is the subject of linguistics, is the house of speaking, understanding, and being with others. Science can examine these phenomena in a precise and powerful way, but it should not suppose that its method captures their full meaning. This is where the analysis of worldhood becomes a critique of scientism, not of science.
Being-in-the-world also shows that place for Dasein is not merely space. Dasein lives in meaningful places. Home, street, school, workplace, city, square, room, threshold, path, and destination are not just points in geometric coordinates for Dasein. They are charged with memory, work, expectation, fear, habit, nearness, and distance. Something may be physically near but existentially distant, or physically distant but very close in my life. Someone waiting for important news may live with a phone in hand that is physically near, but its meaning is bound up with the future, anxiety, and possibility. Thus, Dasein's worldhood transforms our understanding of space and place. Dasein does not stand in neutral space; it dwells in meaningful places.
This point is developed in the later Heidegger's discussions of dwelling, the bridge, the thing, and the fourfold, but its roots are in “Being and Time”. Being-in-the-world means that Dasein is from the start at home somewhere, not in the sense of geographical ownership, but in the sense of being familiar with a horizon of meaning. Even homelessness is only possible for a being who is structurally at home in a world. Someone who has no home has not just lost a roof; they have lost a possibility of dwelling, security, meaning, and belonging. Of course, “Being and Time” does not directly develop this social and political discussion, but the analysis of worldhood opens the way for it. If man is from the start in the world, then the destruction of the world—the destruction of home, language, environment, and social relations—is not merely external damage; it is damage to the structure of man's Being.
Here one can also see one of the limitations of “Being and Time”. Heidegger analyzes worldhood ontologically, but he does not sufficiently address how real worlds are constructed by power, class, gender, colonialism, the state, capital, and institutions. The world of a worker, a woman, an immigrant, a child, an elderly person, a disabled person, a prisoner, a patient, or a marginalized person is still ontologically a world, but its objective structures are different. Equipment, places, streets, languages, and possibilities are not disclosed in the same way for everyone. Thus, Heidegger's analysis of worldhood must be supplemented by social and political analysis. He shows that man is always in the world; but one must add that worlds are not built equally, and Dasein's possibilities are opened or closed in different ways in different historical worlds.
Nevertheless, this very possibility of social critique also comes from Heidegger himself. If one understands man as an inner subject, one may regard society and history as external and secondary affairs. But if one understands Dasein as Being-in-the-world, then it becomes clear that the social, linguistic, instrumental, and institutional world is part of man's very Being. Changing the world means changing Dasein's possibilities. Poverty, discrimination, oppression, migration, the housing crisis, environmental destruction, or the domination of technology are not merely external conditions; they change the way the world is disclosed. Thus, Heidegger's ontology, if supplemented, can provide a profound foundation for a critique of the modern world. He does not fully provide the language for analyzing the social structures of power, but he opens the existential horizon of the importance of the world.
Being-in-the-world also prepares the ground for the meaning of truth. If Dasein is from the start in the world, and beings in the world become manifest for Dasein, then truth cannot be merely the correspondence of a proposition with reality. Prior to a proposition being true or false, a world must be disclosed in which something can appear “as” something and be spoken about. For example, before one can say "the hammer is on the table," a world of equipment, table, work, place, language, and gesture must be disclosed. Propositional truth is based on a prior kind of unconcealment. This discussion appears more fully in “Being and Time” in the analysis of truth, but its root is in worldhood. Worldhood means the primary disclosedness in which any judgment and knowledge become possible.
From this perspective, Being-in-the-world is not merely a concept about man; it is a fundamental critique of the entire tradition that began philosophy from the relation of mind and world. Heidegger shows that mind and world, subject and object, theory and reality, are all possible on the basis of a prior structure: the disclosedness of the world. This disclosedness is neither merely subjective nor merely objective; neither inside man nor outside him in the simple sense. Dasein is the being that stands in this disclosedness and through it understands itself, others, and beings. Thus, if philosophy begins from subject and object, it has begun from a derivative result. The more fundamental beginning is Being-in-the-world.
This point has an important consequence for understanding the self. Man is not a being that first has a complete essence or identity and then is placed in a world. He is formed from the start with his world. Language, place, equipment, others, history, and possibilities are involved in his very Being. Without the world in which I work, speak, love, fear, hope, and die, I am not the same I. The world is not an external environment for Dasein; it is part of the structure of his Being. Thus, changing the world is not just changing man's surroundings, but changing man's possibilities. The technological world, the traditional world, the religious world, the consumer world, the wartime world, the world of exile, the academic world, or the digital world each disclose and limit Dasein in a specific way.
In conclusion, one can say that the concept of Being-in-the-world is Heidegger's main path for moving beyond the philosophy of consciousness, individualistic psychology, and naive realism. Dasein is not a mind against the world, but Being in the world. The world is not a collection of present objects, but a horizon of significance and reference. Things first appear as ready-to-hand equipment in a network of action, and only at a derivative level become present objects for theory. Others are from the start present in Dasein's world, and everyday life is formed in the horizon of the "they," public language, and the possibility of falling. Science, theory, knowledge, and judgment are all based on this prior disclosedness. Thus, Being-in-the-world is not one of Dasein's properties, but his fundamental structure. Dasein means the being whose Being always occurs in a meaningful, shared, practical, historical, and temporal world.
This section shows why “Being and Time” is not merely a book about the individual or the mind. Heidegger from the start understands man in the world, and the world in relation to man, without falling into simple idealism or realism. Being-in-the-world opens a horizon in which the subsequent concepts of the book can be understood: the "they," falling, anxiety, care, death, and temporality. Because Dasein is in the world, it can get lost in the world; because the world is meaningful for it, it can lose the meaning of the world; because it is with others, it can dissolve in the "they"; because it is engaged with equipment and tasks, it can hide itself in occupations; and because the world is the horizon of its possibilities, it can be called from within this very world to its own distinctive possibility. Thus, Being-in-the-world is the beginning of all subsequent analyses; the place where Heidegger moves beyond subject and object and understands man as the worldly disclosedness of Being.
Equipment, Readiness-to-Hand, and Presence-at-Hand: A Critique of the Theoretical Gaze upon the World
One of the most important achievements of “Being and Time” is that Heidegger lowers man's relation to the world from the level of theoretical knowledge and objective observation to a more fundamental level: practical engagement and everyday living. To do this, he turns to a phenomenon that appears in appearance very simple and even trivial: “equipment”. The hammer, the pen, the table, the shoe, the door, the key, the lamp, the house, the road, the dish, the phone, and thousands of other things we deal with in everyday life are for Heidegger not merely material objects. They are a way of understanding how the world is disclosed for Dasein prior to any theory and prior to any science. Traditional philosophy often began from the present object, from the object placed before the mind; but Heidegger shows that in our primary experience, things appear not as neutral objects, but as equipment ready for work, use, movement, building, and living. This small shift transforms the entire horizon of modern epistemology and ontology.
In the theoretical view, the world is a collection of present objects. A hammer can be described as follows: it is an object with a wooden or metal handle, a heavy head, a specific weight, a certain shape, a measurable size, and a particular function. This description is not wrong, but for Heidegger it is not the primary and fundamental description of the hammer. In everyday life, we usually do not encounter the hammer in this way. A carpenter working with a hammer does not, in the moment of work, look at the hammer as an object with physical properties. He "uses" the hammer. The hammer in his hand is an extension of action; it is something for driving a nail, for building a table, for repairing a house, for accomplishing a task that lies within a larger horizon of meaning. The hammer is understood in its use. This mode of appearance of equipment Heidegger calls “readiness-to-hand” (“Zuhandenheit”). Readiness-to-hand means that something appears not as an object of observation, but as available for action and within a network of references.
Readiness-to-hand is more fundamental than it seems at first glance. When equipment works properly, the equipment itself is usually not the focus of our attention. A pen with which we write, as long as it writes smoothly, is not the object of our explicit awareness. We attend to the writing, the meaning, the sentence, and our purpose, not to the pen itself. A shoe with which we walk, if comfortable, is less noticeable; we think of the destination, the path, or the task we are doing, not of the shoe. The door of a room, if it opens and closes properly, is just part of the natural flow of coming and going. A key, if it works, is almost invisible; it dissolves in the action of opening the door. This invisibility is not a sign of the equipment's insignificance; on the contrary, it shows that equipment in its proper function is more of a "path" than an "object." Equipment disappears in the work so that the world of work can remain disclosed.
This analysis is a serious critique of the tradition that considers theoretical presence as fundamental. Philosophy and science usually understand something when they detach it from the flow of action and place it before themselves. To study an object, one must stop it, measure it, describe it, classify it, and analyze it. This is necessary for science. But Heidegger says this mode of understanding is derivative from a more fundamental mode. The hammer is first equipment and only later can become a physical object. The pen is first something for writing and only later can become the subject of material, industrial, or aesthetic examination. The house is first a place for dwelling and only later can become a building unit, property, capital, map, or architectural object. Thus, the theoretical view emerges from the practical world, not the other way around. The world is first disclosed as a field of action and meaning, and only later can it become a world of theoretical objects.
Heidegger uses the concept of “presence-at-hand” (“Vorhandenheit”) to understand this transition. Presence-at-hand is a mode of Being of beings in which something stands before us as an object present. When the hammer breaks, it suddenly emerges from the flow of work. Until then, the hammer was invisible in the action of hammering; but when its handle breaks or its head becomes loose, our attention is drawn to the hammer itself. Now we look at it, examine it, think about its material, weight, cause of damage, or possibility of repair. The equipment has emerged from readiness-to-hand and moved toward presence-at-hand. What was previously dissolved in the work now appears before us. The breakdown of equipment reveals its hidden worldhood. It is from such moments of disturbance that one can understand how the equipment previously functioned within a network of meaning.
This example can be easily seen in everyday life. As long as the internet works, we usually do not attend to the network itself; we are reading, writing, searching, conversing, or doing work. But when the connection is cut, the internet suddenly appears as something problematic. The modem, cables, settings, provider, speed, errors, and infrastructure all enter our awareness. As long as the car works properly, the driver is more engaged with the route, destination, traffic, and movement; but when the car stalls, the engine, battery, fuel, wiring, and mechanic become the focus of attention. As long as the body is healthy, we usually experience the world through the body; but during pain or illness, the body itself becomes something present, heavy, and problematic. These examples show that presence-at-hand usually emerges from a disturbance in readiness-to-hand.
Of course, one should not think that presence-at-hand is something wrong or worthless. Heidegger does not mean to say that the theoretical view is false. Science, engineering, medicine, design, repair, and philosophy all require presence-at-hand to some extent. To build a tool, analyze a disease, design a bridge, or write a theory, one must detach things somewhat from the practical flow and think about them. Heidegger's concern is not a simple value judgment, but an ontological priority. Presence-at-hand is based on readiness-to-hand. Theory is based on practical life. Science is based on a pre-scientific world. If this priority is forgotten, man may suppose that the theoretical way is the primary and exclusive way of encountering the world. The result of such a forgetting is a world in which everything is transformed into object, data, material, technical problem, or object of control.
To understand readiness-to-hand, one must also pay attention to the concept of the “totality of equipment”. No equipment is equipment by itself. The hammer without the nail, the nail without the board, the board without building, building without a house or means, the house without dwelling, and dwelling without Dasein's possibilities has no meaning. Equipment is always within a network of references. Heidegger explains this network with the structure of the "in-order-to." The hammer is in-order-to hammer, hammering is in-order-to join, joining is in-order-to build, building is in-order-to dwell or work, and all of these ultimately lead back to some possibility of Dasein. Thus, equipment is not something isolated; each piece of equipment is a window into a whole world of work, meaning, roles, skills, and purposes. When we deal with a piece of equipment, we are dealing with a world in which that equipment has its place.
This referential network is precisely what reveals the worldhood of the world. The world is not made of isolated objects, but of relations. A table in a classroom is not the same as the same table in a home, a courthouse, a workshop, or a hospital, even if it is materially identical. The meaning of the table comes from the network in which it is placed: the teacher's table, the dinner table, the judge's table, the operating table, the work table. This same material object acquires different meanings in different worlds because it is placed in different networks of reference. This does not mean that the object can have any meaning; rather, it shows that the object is understood in its worldhood. The world is the field of meanings in which things find their place. Readiness-to-hand is the mode in which things are present in this field.
From this perspective, equipment is always related to Dasein, but not in a subjectivist sense. The meaning of equipment comes from its use and referential network, and this network ultimately connects to Dasein's possibilities. But Dasein does not arbitrarily create this meaning. One cannot make anything into any tool one wants, regardless of material, structure, skill, tradition, the shared world, and objective limitations. The hammer, with its physical structure, makes hammering possible; but what hammering means is clarified in the world of work and building. Thus, readiness-to-hand is neither merely subjective nor merely objective. Equipment acquires meaning in the relation between material, function, skill, tradition, the shared world, and Dasein's possibilities. This is the point where Heidegger moves beyond the simple duality of mind and world.
The analysis of readiness-to-hand also shows that understanding prior to theory is often bodily and skillful. Heidegger does not analyze the body in detail in “Being and Time”, but the analysis of equipment effectively shows that Dasein understands the world through its body. The carpenter does not just have information about the hammer; his hand knows the weight of the hammer, the impact, the resistance of the wood, and the rhythm of the work. The driver does not just know driving rules theoretically; his body senses distance, speed, pedal pressure, and steering wheel movement. The writer, the musician, the cook, the athlete, or the doctor all deal with a kind of bodily and practical understanding of the world. This understanding is not present in theoretical propositions, but it is very precise and complex. Readiness-to-hand shows that human understanding is at its core skillful, practical, and engaged.
This point is important for the critique of abstract rationalism. The philosophical tradition has usually considered theoretical reason and explicit propositions as the highest form of understanding. But Heidegger shows that prior to theoretical understanding, a kind of practical understanding is at work, without which no theory would be possible. Someone who has never lived in a practical world cannot even understand the meaning of theoretical concepts. Words like equipment, work, home, path, danger, help, failure, success, and possibility all arise from practical life. Theory is not separate from life; it is an abstraction made possible on the basis of the lived world. This does not mean being anti-reason; it means a critique of the domination of theoretical reason over all forms of understanding. Heidegger wants to show that man, before being a theoretical being, is a being engaged with the world.
In this analysis, “disturbance” has a significant philosophical place. As long as equipment works, the practical world remains hidden. But the breakdown, loss, obstacle, or malfunction of equipment reveals the hidden network of references. When I forget my keys, suddenly the door, the house, entry, access, security, expectation, and my dependence on equipment become clear. When the power goes out, a vast network of dependencies is revealed: light, heat, communication, work, production, security, food, elevators, internet. When a software program crashes, the task that seemed simple and natural becomes a complex network of code, device, company, user account, connection, and permissions. Disturbance brings the world out of concealment. Thus, philosophy can learn from moments of failure, breakdown, and interruption, because in these moments what was usually obvious becomes questionable.
The same logic can be applied to social life. Many institutions are invisible as long as they work. Law, trust, money, transport, education, shared language, healthcare, urban infrastructure, and communication networks are usually in the background of everyday life. But when one of them faces a crisis, it suddenly becomes apparent how much our life depended on it. Economic crisis, war, pandemic, communication disruption, forced migration, or institutional collapse, like the breakdown of equipment, reveal the hidden worldhood of collective life. Heidegger does not develop this discussion at a political and social level, but his analysis of equipment can contribute to understanding these phenomena. The world always depends on networks that, as long as they work, are less visible.
Readiness-to-hand also shows that "use" should not be understood superficially. One might think that Heidegger, through the analysis of equipment, understands the world merely in terms of utility and practice, and thus approaches a kind of simple pragmatism or utilitarianism. But Heidegger's point is not that the value of things lies only in consumption or usefulness. On the contrary, he wants to show that practical use is more fundamental than theoretical observation, but this use itself is situated in a meaningful world. Equipment is not merely a means to an end; it is placed in a network of life, skill, tradition, role, and possibility. Even things that are apparently not equipment, such as a work of art, a sacred place, a family heirloom, or a beloved book, appear in a kind of network of meaning. Thus, the discussion of readiness-to-hand is a path to understanding worldhood, not a reduction of everything to instrumentalism.
Nevertheless, this analysis also prepares the ground for Heidegger's later critique of technology. In “Being and Time”, equipment has meaning in Dasein's everyday world and is still placed in a network of work, dwelling, and human possibilities. But in modern technology, the danger is that all beings are understood not as ready-to-hand equipment in the lived world, but as a calculable reserve and resource. There is an important difference between traditional equipment and modern technology. The hammer in the carpenter's hand is within a meaningful flow of work; but the power plant, industrial network, or data system prepares and stores the world on a different scale. In “Being and Time”, the discussion of “Gestell” is not yet raised, but the analysis of equipment is one of the roots of Heidegger's later understanding of technology. He shows from the start that the mode of appearance of things has ontological significance. Later he will say that modern technology is a specific and dangerous mode of this appearance.
Another point is that readiness-to-hand always occurs within a shared world. Equipment is usually not made for purely individual use; it is placed in a tradition of work, education, skill, language, and community. Someone who picks up a hammer is already in a world where building, repairing, carpentry, house, tools, and work have meaning. This world has come from others. Even individual skill is learned in a collective tradition. Thus, equipment carries history and society. A pen is not just a writing instrument; it is related to the history of script, education, language, paper, school, office, literature, and human communication. A mobile phone is not just a technical device; it brings with it a world of communication, work, market, data, loneliness, entertainment, and surveillance. Equipment carries worlds. Readiness-to-hand means being placed in these meaning-laden worlds.
This point is very important in the digital age. Digital equipment often works so smoothly and invisibly that it conceals its own worldhood. A smartphone, as long as it works, is just a tool for communication, photos, messages, maps, payment, reading, and entertainment. But behind this readiness-to-hand is a vast network of servers, companies, algorithms, data, workers, mines, energy, politics, laws, and psychological habits. When the device breaks, the account is blocked, the network is cut, or data is lost, this hidden world suddenly becomes apparent. Heidegger's analysis of equipment can help us understand that modern equipment is not just isolated objects; they are compressed worlds that organize our way of life. They are ready-to-hand, but this very readiness-to-hand can conceal dependency and domination.
Thus, readiness-to-hand has two faces. On one hand, it is a condition of human life. Without equipment, practical world, skills, and references, Dasein cannot live. Equipment makes the world habitable, workable, and understandable for us. On the other hand, this same equipment can trap us in a network of occupation and invisibility. When everything works smoothly, we may ask less about what these networks do, how they shape us, and what possibilities they open or close. Breakdown and interruption are sometimes an opportunity for thought, because they pull us out of the natural flow of consumption and use. Heidegger teaches us that even the simplest equipment is not just equipment; they are ways of disclosing the world.
Presence-at-hand must also be understood in its place. If readiness-to-hand is the primary mode of everyday encounter with things, presence-at-hand provides the possibility of distancing, observing, analyzing, and theorizing. Without presence-at-hand, science and philosophy would not be possible. But the problem begins when presence-at-hand becomes the “only” model for understanding beings. In that case, man, body, language, home, city, nature, and even God and art are understood as objects present for examination, control, or consumption. The home becomes property, the body a biological machine, language a code, man a statistical unit, nature raw material, and art a museum object. This reduction is, for Heidegger, one of the roots of the modern crisis. Presence-at-hand, if it takes the place of all other modes of appearance, impoverishes the world.
Thus, the critique of the theoretical gaze on the world is not a critique of science or reason; it is a critique of the absolutization of a particular mode of disclosedness. Man needs theory, but he does not live by theory alone. We experience the world through the body, habit, skill, affect, language, memory, work, art, religion, love, fear, hope, and death. Whenever one of these modes is eliminated in favor of the theoretical gaze, the world loses part of its richness. “Being and Time” wants to reveal this pre-theoretical richness. The analysis of equipment is one of the main ways of doing this, because equipment shows that the world, before being an object of knowledge, is a field of living. We are in the world before we have theories about it.
In conclusion, one can say that the analysis of equipment, readiness-to-hand, and presence-at-hand in “Being and Time” is not merely a limited discussion about everyday objects; it illuminates the entire philosophy of Heidegger. Through equipment, Heidegger shows that the world is from the start meaningful, referential, practical, and shared. Things first appear in their function and relations, not as neutral objects. The theoretical and scientific view, though necessary and valuable, is derived from the prior disclosedness of the practical world. Breakdown and disturbance of equipment show that worldhood is usually hidden and only reveals itself in interruptions. This analysis sets aside the philosophy of subject and object and opens the way for understanding Dasein as Being-in-the-world. It also provides a foundation for Heidegger's later critiques of technology, scientism, and the reduction of the world to a calculable resource.
Thus, if Dasein is a being that lives in the world, equipment is the first sign of this worldhood. It shows that human Being always occurs within a network of meaning, action, skill, others, and possibilities. No hammer is merely a hammer, no house is merely a building, no pen is merely a thin object, no phone is merely an electronic device. Each thing has meaning in a world, and each world is related to Dasein, to his possibilities, to his history, and to his way of dwelling. Through the analysis of equipment, Heidegger compels us to ask again about the simplest things. Philosophy begins here: from seeing what has always been before us, but because of its excessive proximity, we no longer see it.
Being-with, the "They," and Everydayness: Dasein in the Shared World
After the analysis of Being-in-the-world and worldhood, Heidegger takes another important step and shows that Dasein's world is never a private, isolated, or merely individual world. Dasein is from the start with others. This “Being-with” (“Mitsein”) is one of the fundamental structures of Dasein's Being, not a secondary state later added to an isolated individual. In modern philosophy, especially after Descartes, it was often assumed that the starting point of philosophy is a solitary, conscious subject; a subject who is first certain of its own existence and then must find a way to prove the existence of the external world and other minds. In such a horizon, the other becomes a difficult problem: how can I know that the being before me is not just a moving body, but has a mind, consciousness, feeling, and experience? Heidegger considers this way of posing the problem fundamentally wrong. Dasein is never first an isolated subject that then reaches others; it is from the start in a world shared with others.
This claim may seem obvious at first glance, but its philosophical consequence is very profound. If Dasein is from the start with others, then the problem of "proving the existence of others" becomes a secondary and artificial problem. In real life, we are not first confronted with inanimate objects and meaningless bodies from which we then infer that some of them are human. Our world is from the start a human, linguistic, instrumental, social, and historical world. A child, before being able to reason about the existence of another mind, lives in the embrace, voice, gaze, care, fear, trust, and language of others. An adult, in every moment, is in a world built, given meaning, named, and continued by others. The house, the street, the school, the university, the market, the law, the language, the equipment, the clothes, the book, the money, the roles, and the customs all show that Dasein's world is from the start a shared world. Even solitude has no meaning without a prior relation to others. One can only be alone if one is structurally with others and experiences their absence or distance.
Being-with for Heidegger is not ethical empathy or friendly relations, though it can take such forms. Being-with is an existential structure. That is, Dasein, even prior to any ethical choice, prior to any social contract, and prior to any personal relationship, is in a world with others. The other is not merely someone standing before me. The other is present in my very world. When I use a language, I speak a language that has come from others. When I use equipment, I am in a network of work, skill, and production in which others are involved. When I dwell in a house or walk in a city, I move in a world built before me and with the hands of others. Even when I read a book in solitude, I am in a relation with the author, tradition, language, printing, education, and the history of reading. Thus, the other is not only present in face-to-face encounter; he is present in the structure of the world.
This point is particularly important for understanding Heidegger's difference from modern individualism. In modern individualism, man is often imagined as an independent individual who then enters society, makes contracts, establishes relationships, or acquires a social identity. Heidegger does not accept such a primordial individual. Dasein is always already in a shared world. Of course, this is not a denial of individuality. Heidegger emphasizes that Dasein is in each case mine and no one can be my Being in my place. But this "mineness" never means primordial isolation. My Being is always formed within a horizon of language, history, tradition, others, and shared possibilities. Thus, Dasein is both singular and shared; its Being is both entrusted to itself and lived in a world with others. The tension between these two dimensions is one of the main sources of the problem of authenticity and inauthenticity in “Being and Time”.
To explain the everyday way of Being-with, Heidegger uses the famous concept of “das Man”, which is usually translated into English as "the they," "the One," "the public," or "everyone." No translation is entirely adequate, because “das Man” in German refers to an indefinite pronoun; the same as when one says in English "one does this," "they say that," "people think this way," or "that's not what is done." “Das Man” is neither a specific person, nor a definite group, nor society in the sociological sense, nor a numerical majority. The "they" is that invisible and everyday force that determines the public interpretations of the world. In everyday life, we often see through the eyes of the "they," speak with the language of the "they," judge by the standards of the "they," and, with the comfort the "they" provides, flee from the direct confrontation with our own possibilities.
The "they" tell us what is important and what is unimportant; what clothes are appropriate and what behavior is strange; what counts as success and what counts as failure; how one should speak about death; about love, work, religion, politics, science, truth, and happiness; and even how one should be worried or joyful. This determination is usually not explicit. There is no specific commander saying to think this way and live that way. The power of the "they" lies precisely in its anonymity and facelessness. Everyone follows, but no one is responsible. Everyone speaks, but there is no specific speaker. Everyone knows, but the knowledge belongs to no one. The "they" relieve Dasein of the heavy responsibility of its Being. They allow it to dissolve in the public world and lift itself off its own shoulders.
In appearance, this situation seems entirely negative, but Heidegger does not condemn it simplistically. The "they" are part of the structure of Dasein's everydayness. Human life without public language, custom, habit, common rules, and ready-made understandings is impossible. If every human being had to construct all meanings from scratch, no shared life would be possible. We need the public world to walk in the city, use equipment, speak, shop, work, learn, and even protest. The "they" provide a kind of possibility for everyday living. They make the world usable, familiar, and low-risk. But this same possibility also carries a great danger: Dasein may become so absorbed in the public interpretation of the world that it no longer sees its own distinctive possibility. It no longer asks how I should be; it sees how the "they" are and repeats that.
Thus, the "they" both comfort and alienate. They comfort because they remove fundamental decision-making from Dasein. When the "they" have already said what is valuable, Dasein does not need to confront the anxiety of choice and responsibility. When the "they" have turned death into a public event, Dasein does not need to understand its own death as its own distinctive and non-transferable possibility. When the "they" have spoken about truth, success, ethics, religion, or philosophy, Dasein can repeat those words and suppose it has understood. But this very comfort brings alienation, because Dasein is no longer itself in it. He lives in a state where everything is familiar, but this familiarity is not his own; everything is understood, but no authentic understanding is at work; everything has been said, but no one has truly spoken.
This situation is linked to the concept of “falling” (“Verfallen”). Falling does not mean moral or religious fall; Heidegger considers it the structure of Dasein's everydayness. In its ordinary life, Dasein is drawn toward the world, tasks, talk, entertainments, judgments, and occupations, and becomes absorbed in them. This absorption is not mere distraction; it is a way of Being. Dasein flees from itself, but not necessarily by a conscious decision. It dissolves in the public world and understands itself through that world. Falling means Dasein does not take itself from its own distinctive possibility, but from ready-made and public interpretations. This situation is always accompanied by a kind of comfort, because the "they" lighten the burden of responsibility. But ontologically, they alienate Dasein from itself.
To explain the structure of falling, Heidegger highlights three phenomena: “idle talk” (“Gerede”), “curiosity” (“Neugier”), and “ambiguity” (“Zweideutigkeit”). Idle talk does not mean talking a lot. One may speak very little but live in idle talk; and one may speak a great deal but have authentic discourse. Idle talk means the circulation of talk without rooting in an authentic encounter with things. In idle talk, words are repeated, circulated, passed from hand to hand, and gain their authority not from seeing and understanding, but from being common. The "they" say it, so it must be true. Everyone has heard it, so it seems understood. Idle talk keeps the world at a level of apparent familiarity. Everything is already explained, but these explanations often prevent a fresh encounter with the things themselves.
Idle talk has taken on a much wider form in today's world. Media, social networks, instant news, short analyses, repetition of slogans, constant reposting of opinions, and rapid consumption of information can all be forms of idle talk. The problem is not that speaking or communicating is bad; the problem is that talk can take the place of understanding. One can talk about everything without having encountered it. About death, politics, religion, philosophy, art, love, technology, and truth, much is spoken, but sometimes these words conceal more than they reveal. Idle talk produces an apparent understanding; one thinks one knows because one has heard, read, or repeated. But this knowing is not one's own. In idle talk, language ceases to be the house of disclosedness and becomes the field of circulation of rootless, ready-made meanings.
Curiosity is the second structure of falling. Curiosity for Heidegger does not mean an authentic desire to know. He has no objection to the desire to learn or seek truth. Curiosity in Heidegger's negative sense means the constant desire to see new things without staying with anything. Curious Dasein constantly seeks the new, fresh news, fresh images, fresh experiences, and fresh stimulation, but cannot abide with anything. It wants to see, but not to understand; to move on to the next thing. Curiosity prevents Dasein from going deep, because it constantly pulls it to the next surface. Such Dasein has contact with everything, but enters into a deep relation with nothing. The world becomes a series of stimuli for it.
This analysis is also very meaningful in the present age. The speed of media, the abundance of images, the constant shifting between news, and the perpetual desire for the newer, hotter, and more different have made Heideggerian curiosity one of the important features of modern life. A person today may move in one hour from war to sports, from philosophy to entertainment, from disaster to advertising, from an image of nature to a personal message, and from scientific news to a daily joke. This rapid movement produces a kind of superficial familiarity with everything, but reduces the possibility of pausing. Curiosity, unlike thinking, does not stay with things. Thinking requires lingering; curiosity requires fresh stimulation. Thus, curiosity is one of the ways Dasein flees from confronting itself and the world.
Ambiguity is the third structure of falling. In ambiguity, everything seems to be understood, but in reality nothing is clear. Idle talk and curiosity together create a space in which Dasein thinks it knows everything. Because everything has been said and everything has been seen, nothing seems hidden anymore. But precisely in this apparent clarity, true understanding is hidden. Ambiguity is the situation in which the difference between authentic understanding and public repetition is effaced. One who has only heard considers themselves on the same level as one who has understood. One who has only seen thinks they have experienced. One who has only repeated a phrase thinks they have thought. Ambiguity empties the world of depth, without this emptiness becoming apparent.
These three phenomena—idle talk, curiosity, and ambiguity—show the structure of fallen everyday life. But one must emphasize that Heidegger is not preaching here. He does not say that humans should not talk, should not be curious, or should not live in the public world. He wants to reveal the existential structure of inauthenticity. Inauthenticity does not mean lying or being bad; it means that Dasein does not understand itself from its own distinctive possibility. It lives at the level of the "they" and flees from the responsibility of its own Being. This flight often occurs so naturally and comfortably that Dasein does not experience it as flight. It thinks its natural life is just this: the same talk everyone talks, the same seeing everyone sees, the same wanting everyone wants, the same fearing everyone fears.
But is it possible to escape the "they"? Heidegger's answer is complex. Dasein can never completely leave the public world. It is always in language, history, equipment, roles, and shared relations. Authenticity does not mean living outside society or cutting off from others. Authentic Dasein is still in the public world, but it no longer takes itself entirely from the "they." It can use public language, but not be captive to idle talk. It can see new things, but not get lost in superficial curiosity. It can live with others, but not surrender the responsibility for its Being to them. Thus, authenticity is not a spatial exit from the world, but a different way of Being in the world. Authentic Dasein, in the same everyday world, establishes a different relation to itself, others, death, and its possibilities.
This point prevents an individualistic misunderstanding of Heidegger. Sometimes authenticity is understood as if Heidegger were inviting man to a kind of heroic individualism, isolation, or indifference to society. But this reading is not accurate. Authentic Dasein is also with others. The problem is not to flee from others, but not to lose oneself in Being-with. One might even say that an authentic relation to others is only possible when Dasein has emerged from complete absorption in the "they." As long as I understand myself only from public standards, I also see the other mostly in those same standards: role, status, utility, threat, public judgment, or social expectation. But if I confront my own possibility, perhaps I can understand the other not merely as part of the "they," but as Dasein with its own possibilities.
Heidegger, in his analysis of the relation to others, distinguishes between two forms of “solicitude” (“Fürsorge”). Dasein relates to things through “concern” (“Besorgen”), that is, dealing and having to do with them; but it relates to other Daseins through “solicitude” or care. This solicitude can be inauthentic: I do the other's work for them, take their possibility away from them, make them dependent, or decide in their place. In appearance, I may have helped them, but in reality I have taken away their possibility of Being. A more authentic form of solicitude is to give the other back to their own possibility; not to be in their place, but to free them so that they can take over their own Being. This distinction is important for a more ethical understanding of Being-with, though Heidegger does not develop it into a complete ethical theory.
From here, one can also point to an important limitation of Heidegger's analysis. He reveals Being-with as an existential structure of Dasein very well, but he does not extensively develop the relation to the other from the perspective of vulnerability, justice, power, and ethical responsibility. The other, for Heidegger, appears mostly within the horizon of the shared world, the "they," and the possibility of authenticity. But philosophers like Levinas later argued that the other is not merely part of the structure of my world; the other is a face that calls me to responsibility. From this perspective, Heidegger's analysis of Being-with is necessary but insufficient. He shows that Dasein is from the start with others, but he shows less how this Being-with should be linked to justice, responsiveness, the suffering of the other, and ethical responsibility. Thus, the ontology of Being-with must be supplemented by an ethics of the other.
The analysis of the "they" can also be extended from a social and political perspective. Heidegger analyzes the "they" as an existential structure of everydayness, but he does not sufficiently address what historical, media, economic, educational, and political forces shape the public interpretation of the world. In the real world, the "they" are not merely a vague and nameless force; media, states, markets, educational institutions, social networks, advertising, ideologies, and structures of power play a role in the production of public understanding. The "they" speak, but this speaking is not always without source. Sometimes behind "everyone says" there is a network of interests, power, capital, and politics. Thus, Heidegger's analysis of “das Man” must be supplemented by a theory of power and ideology. Nevertheless, he correctly reveals one of the most fundamental forms of anonymity and irresponsibility in collective life.
The importance of this analysis in our time is very great. Modern man is more than ever subject to public discourse, public judgment, public image, and public standards. Communication networks, media, and the digital space have not made the "they" disappear; they have perhaps made it more widespread and faster. Now "everyone" can say something at any moment, judge, approve or reject, make famous or forget. In such a world, Dasein is more than ever in danger of understanding itself from the eyes of others, from numbers, likes, views, trends, and public judgments. The "they" are no longer only present in the neighborhood and marketplace; they are present on the screen, in notifications, messages, and the endless flow of opinions. But the structure is the same: Dasein can get lost in "what everyone says."
Yet the possibility of authenticity has not disappeared. Precisely in the heart of this shared world, Dasein can be called. Sometimes anxiety, failure, silence, death, loss, responsibility, love, commitment, or a deep encounter with truth pull back the curtain of the "they." In such moments, what was previously obvious is no longer enough. Public speech no longer comforts. Dasein realizes that it cannot completely surrender its Being to others. This is where the path opens to the later concepts of “Being and Time”: anxiety, death, conscience, and resoluteness. Heidegger shows that to reach authenticity, Dasein does not need to leave the world; it must change its relation to its own Being within the world. The "they" are a covering, but this same covering can be lifted in a moment.
Thus, Being-with and the "they" are two sides of a single truth. Dasein is from the start with others, and without this Being-with, there would be no human world at all. But this same Being-with can in everydayness become the domination of the "they" and alienate Dasein from itself. The shared world is both the condition for the possibility of language, understanding, work, and life, and the field of losing oneself, repetition, idle talk, and inauthenticity. Dasein must take over this duality. It cannot return to a pre-social, innocent individuality, because such a state does not exist. It cannot dissolve itself completely in the collective, because its Being is in each case its own. It must, in the shared world, take over its own distinctive possibility. This is the difficulty of being human for Heidegger: we are always with others, but no one can be ourselves in our place.
In conclusion, one can say that Heidegger's analysis of Being-with, the "they," and everydayness is one of the deepest parts of “Being and Time”, because it shows that man is neither an isolated subject nor merely a product of society. Dasein is a being that lives in the shared world, takes language and meaning from others, finds comfort and loss in the "they," moves through idle talk, curiosity, and ambiguity, and yet always has the possibility of returning to itself. This return is not leaving others, but taking over one's own Being among others. Through the analysis of the "they," Heidegger shows that inauthenticity is not an unusual or exceptional state; it is the usual form of our everyday life. But this same everyday life, if properly understood, can open a path to a deeper question: how can I, in a world that has already interpreted everything, take over my own Being?
Falling, Idle Talk, Curiosity, and Ambiguity: The Structure of Inauthenticity in Everyday Life
In Heidegger's analysis of Dasein, everyday life occupies a completely fundamental place. Unlike many philosophical traditions that sought the truth of man in theoretical reason, pure intuition, abstract reflection, specific religious experience, or exceptional situations, Heidegger begins precisely where Dasein usually finds itself: the everyday world. Dasein is mostly engaged in work, relationships, talk, concerns, plans, habits, roles, and public judgments. It finds itself in a world already interpreted, already named, already valued, and already presenting the possible paths of life before it. This everyday world is neither something superficial and insignificant nor merely an external obstacle to truth; it is the very field in which Dasein's fundamental structures are revealed. But this revelation is always accompanied by concealment. In everyday life, Dasein both shows itself and flees from itself. The concept of “falling” (“Verfallen”) is the name for this dual condition.
Falling in “Being and Time” does not mean moral fall, religious sin, or psychological corruption. Heidegger uses this word with ontological precision. Falling means that in its everyday life, Dasein slips into the world of occupations, the "they," ready-made interpretations, and public meanings, and understands itself from them. Instead of taking over its own distinctive possibility, it finds comfort in what "everyone" says, wants, and does. This comfort is not necessarily accompanied by suffering or a sense of failure; on the contrary, it often appears very natural, calm, useful, and even successful. In falling, Dasein may work, progress, speak, have relationships, gain social respect, and live a completely normal life. The problem is not that he lives morally badly; the problem is that he does not take his Being from his own authentic possibility, but from the public world.
In this sense, falling is a kind of alienation of Dasein from itself, but this alienation does not mean leaving Dasein's essence. Dasein is a being that is from the start in the world and with others; thus, it is always in danger of becoming absorbed in the world and in others. Falling is Dasein's intrinsic possibility, not an accidental occurrence. Because Dasein is worldly, it can become absorbed in the world. Because it is with others, it can dissolve in the "they." Because it has language, it can get lost in public talk. Because it has understanding, it can take its understanding from ready-made interpretations. Because it is possible, it can lose its own possibilities and surrender itself to public possibilities. Thus, falling is not something outside Dasein, but one of the possible ways of its Being. Being human means always being in danger of living in ready-made obviousness instead of living one's own possibility.
Heidegger highlights three phenomena to describe the structure of falling: “idle talk” (“Gerede”), “curiosity” (“Neugier”), and “ambiguity” (“Zweideutigkeit”). These three phenomena are not merely bad behaviors or undesirable habits; they are ways in which Dasein in the everyday world distances itself from an authentic encounter with itself and with things. Idle talk shows how language can be transformed from the disclosedness of truth into the rootless repetition of public meanings. Curiosity shows how seeing and becoming aware can degenerate into the superficial consumption of novelties. Ambiguity shows how in the everyday world the boundary between understanding and not understanding, knowing and merely hearing, experiencing and merely seeing, collapses. These three structures together constitute the space of everyday inauthenticity.
Idle talk for Heidegger does not mean speaking a lot. Someone may be very talkative, but their talk may arise from a living and authentic encounter with the subject; and someone may speak very little, but that same little talk may be a rootless repetition of public talk. Idle talk means that language is detached from its living relation to things and gains its authority from public circulation. In idle talk, something is considered true because "it is said," not because it has been seen, understood, or tested. Talk, instead of being a path to disclosedness, itself becomes a cover over things. In idle talk, Dasein speaks about everything, but not necessarily out of understanding. It speaks about death without having understood its own death; about truth without having stood before truth; about art, religion, politics, philosophy, love, freedom, and life, but these talks come more from the public world than from authentic encounter.
Idle talk is dangerous because it produces the appearance of understanding. When something is constantly said, it seems clarified. When a saying circulates among the "they," it seems to gain authority. When a word is repeated many times, its meaning seems obvious. But precisely this apparent obviousness prevents questioning. Idle talk calms the world, because Dasein no longer needs to see for itself, think for itself, or encounter things for itself. It can say what is said. This condition is unavoidable in everyday life; because language is always public and we take language from others. But the danger is when public language replaces authentic encounter. In idle talk, language is no longer the house of disclosedness; it is the marketplace for the circulation of ready-made meanings.
This analysis has a double power in today's world. Modern life is saturated with talk, messages, news, analyses, opinions, slogans, image-texts, instant reactions, and short speeches. In such a world, man may think he knows a great deal, because he has heard something about everything. But hearing a lot is not necessarily understanding. The speed of the circulation of talk reduces the possibility of lingering. Every event, before being understood, is interpreted; before being experienced, an opinion is given about it; before it reaches depth, it becomes a consumed subject. Idle talk is not only in oral conversation; it is also present in the media structure of the modern world. Of course, Heidegger does not speak of the digital world in his time, but the structure he describes is seen with greater intensity in the age of pervasive media. Today, the "they" do not only speak in the neighborhood, café, and newspaper; they are present in the endless flow of networks, notifications, and reposts.
But idle talk is not the only form of falling. Dasein in everydayness does not merely speak; it wants to see. This desire to see, in its inauthentic form, is curiosity. Curiosity for Heidegger does not mean an authentic interest in knowing. He has no objection to questioning, learning, or seeking truth. On the contrary, the whole of “Being and Time” is a vast effort to question. What Heidegger calls curiosity is a restless desire for novelty; a seeing that does not want to stay with anything. Curious Dasein moves from one thing to another, from news to news, from image to image, from experience to experience, from talk to talk. It wants to have seen everything, but not in order to understand; in order to flee from staying with one thing. Curiosity keeps Dasein at the surface level of movement. It is constantly passing by.
The difference between thinking and curiosity lies precisely in this staying. Thinking pauses with something. It lets the phenomenon show itself. It does not hurry to move on to the next thing. But curiosity fears stillness, because stillness might confront Dasein with itself. Curiosity wants always something new so that Dasein is not forced to ask itself what it wants, what it understands, where it is going, and how it lives. In appearance, curiosity brings Dasein close to the world, but in reality it distances Dasein from the world, because it transforms the world into a series of passing stimuli. One who only wants to see may never really see. Authentic seeing requires attention, patience, silence, and engagement. But curiosity reduces seeing to the consumption of spectacles.
In modern life, curiosity is not merely an individual habit but a cultural structure. The attention economy is built on this desire for novelty. Every moment something new, urgent, attractive, different, and stimulating must be offered. Fresh news, fresh images, fresh messages, fresh crises, fresh entertainments, and fresh experiences keep Dasein in perpetual motion. This motion, in appearance, is a sign of awareness and connection to the world; but it may be a new form of getting lost. Man is present everywhere, but stays with nothing. He sees everything, but understands less. He is in contact with the world, but his contact is often superficial and passing. Heidegger, with his analysis of curiosity, recognized this danger very early: seeing can, instead of disclosing the world, transform the world into a shallow surface of consumable novelties.
Idle talk and curiosity together produce ambiguity. Ambiguity is the situation in which everything appears clear, but in reality nothing has truly become Dasein's own. In ambiguity, Dasein thinks it understands, because it has heard about things and seen them. But its hearing and seeing have mostly remained at the level of the "they." Ambiguity is more dangerous than obvious ignorance, because ignorance may lead one to question, but ambiguity produces a feeling of knowing. In ambiguity, it is no longer clear who has truly understood and who has merely repeated; who has experienced and who has merely seen; who has thought and who has merely reacted. Everything is placed at a level of public familiarity. The world is no longer strange, but this familiarity is not authentic familiarity.
Ambiguity is the main field of the domination of the "they." In the world of the "they," everything already has an interpretation. Everyone has an opinion about everything. Every event is already placed in a ready-made framework. As soon as something happens, it is immediately known how to speak about it, how to understand it, how to react to it, and what position to take. In such a world, Dasein has less opportunity to encounter the event itself. It mostly encounters an interpretation that was prepared before it. This interpretation may be right or wrong, but the main problem is that Dasein has not made it its own. Ambiguity excuses Dasein from the necessity of understanding. It can float in the public space, without clarifying its relation to truth.
Here one must note that Heidegger does not present idle talk, curiosity, and ambiguity as merely negative phenomena against a positive truth. These are ways of Dasein's Being and are rooted in his fundamental structures. Idle talk is possible because Dasein has language. Curiosity is possible because Dasein is world-disclosing and seeing. Ambiguity is possible because Dasein has understanding and lives in the shared world. Thus, each of these phenomena is the fallen form of an authentic possibility. Language can disclose truth, but it can also fall into idle talk. Seeing can be a path to understanding, but it can also degenerate into curiosity. Shared understanding can build dialogue and tradition, but it can also sink into public ambiguity. This duality shows that inauthenticity is not something outside man; it is the shadow of his own possibilities.
Falling is also linked to a kind of flight from anxiety. Dasein in everydayness busies itself with thousands of things so as not to confront itself, its finitude, its possibilities, and the ultimate groundlessness of the everyday world. The "they" tell him that everything is clear, everything is normal, life is just this, death is for everyone, one must work, one must succeed, one must be like others, one must be entertained, one must know what they say. This familiar world protects Dasein from anxiety. But anxiety, as we will see in the next section, robs this familiar world of its validity. In anxiety, Dasein realizes that the everyday world and the interpretations of the "they" cannot be the ultimate foundation of its Being. Thus, falling must be understood as Dasein's flight from confronting its own fundamental homelessness. Dasein finds an apparent home in the "they," but this home is always in danger of collapsing.
One of the most important features of falling is that it conceals itself. Fallen Dasein usually does not know that it has fallen. It considers its everyday life natural, obvious, and even successful. Because the "they" provide public standards, Dasein can measure itself by those standards and be at ease. If it wants what everyone wants, says what everyone says, and has the same fears and desires as everyone else, it feels less alienated. Falling is precisely powerful for this reason: it presents itself as home, habit, and security. But existentially, this security is based on forgetting. In falling, Dasein forgets its Being; not in the sense that it no longer exists, but in the sense that it no longer experiences its Being as an issue for itself.
This analysis helps us understand that inauthenticity in “Being and Time” is not an exceptional state. Heidegger does not say that some humans are inauthentic and others are always authentic. Inauthenticity is the usual and predominant way of Dasein's Being. Dasein is initially and for the most part in the "they." Authenticity is not something one has from the start and just needs to preserve; authenticity is a possibility that is disclosed from within inauthenticity and against it. Dasein must become aware of its lostness to be able to return to its own possibility. Thus, inauthenticity is the presupposition for understanding authenticity. One who has never gotten lost in the "they" is not, in Heidegger's sense, Dasein. Being human means living in a shared and everyday world; and this living always carries the possibility of getting lost in itself.
Nevertheless, there is a great danger in a superficial reading of this discussion. One might suppose that Heidegger despises everyday life, society, communication, media, public talk, and curiosity, and opposes them with a kind of isolated, heroic, and silent life. This reading is simplistic. Heidegger does not negate everyday life; he reveals its structure. Authentic Dasein also still speaks, sees, lives with others, works, and is present in the public world. The difference is in the “way” of Being. Authentic speech can arise from public language, but not be rootless repetition. Authentic seeing can engage with the world, but not be reduced to the consumption of novelty. Living with others can be accompanied by responsibility, not complete dissolution in the "they." Thus, authenticity is not leaving the world; it is a transformation of the relation to the world.
Idle talk, curiosity, and ambiguity are also important in relation to truth. In these three phenomena, truth in the sense of unconcealment and disclosedness is damaged. Idle talk covers things with ready-made talk. Curiosity does not allow things to reveal themselves in their depth. Ambiguity confuses the difference between disclosedness and concealment. Thus, falling is not merely a human problem, but a problem related to truth. Fallen Dasein lives in a world where things appear disclosed, but this apparent disclosure is a kind of concealment. This point is important for Heidegger's entire philosophy, because he understands truth not only at the level of true and false propositions. Truth is prior to all that disclosedness; and falling shows that Dasein's disclosedness is always in danger of being concealed.
Here one can see a link between “Being and Time” and Heidegger's later works. Later, when Heidegger speaks of technology, “Gestell”, language, art, and the forgetting of Being, he is still engaged with the same fundamental problem: how can something, while appearing disclosed, remain concealed? In the technological world, everything appears disclosed, measurable, recordable, and controllable; but perhaps Being itself is more concealed than ever. In Dasein's everyday life, everything appears understood, said, and seen; but Dasein's own Being remains hidden. Thus, falling in “Being and Time” is an existential example of the same larger logic that in the later thinking becomes the forgetting of Being. Dasein in idle talk, curiosity, and ambiguity forgets itself; the history of metaphysics, on a broader scale, forgets Being.
From a critical perspective, one can say that Heidegger's analysis of falling is very deep, but it must be supplemented by social and political analysis. He correctly shows how the "they," idle talk, curiosity, and ambiguity keep Dasein in inauthentic everydayness. But he does not sufficiently explain how these public structures are produced and reinforced by institutions, media, economics, political power, and educational systems. In the contemporary world, idle talk is not merely an existential possibility of language; the media industry, advertising, social networks, and the politics of public opinion also organize it. Curiosity is not merely Dasein's desire for novelty; the attention economy stimulates and manages it. Ambiguity is not merely the structure of public understanding; it is sometimes the result of the deliberate production of contradictory information, propaganda, and manipulation of opinion. Thus, Heidegger's ontological analysis must be supplemented by a critique of ideology, a political economy of media, and a theory of power.
Despite this limitation, the power of Heidegger's analysis remains. He sees something that even many social theories sometimes overlook: that the problem is not merely the incorrect content of talk or false information, but the way we are with talk, seeing, and understanding. The information may be correct, but our relation to it may be inauthentic. The news may be true, but its consumption may occur in superficial curiosity. A statement may be precise, but in the circulation of idle talk it may become a cliché. Thus, the problem is not just "what" is said, but "how" Dasein lives in language and the public world. This level of analysis makes Heidegger still essential for understanding our time.
Falling ultimately leads us to the question of authenticity. If Dasein is initially and for the most part in the "they," how can it emerge from this situation? Heidegger's answer does not begin with a moral imperative, psychological advice, or social program. He shows that in the structure of Dasein itself there is a mood that can pull aside the cover of the everyday world: “anxiety”. Anxiety is different from fear. Fear is always of something specific in the world, but anxiety empties the entire everyday world of its usual meaning. In anxiety, the "they" are no longer a sufficient shelter, public talk does not comfort, curiosity does not entertain, and ambiguity collapses. Dasein in anxiety confronts its own Being, its possibilities, and the groundlessness of everyday comfort. Thus, the next section of Heidegger's analysis is devoted to anxiety, because anxiety is the point of rupture in falling.
In conclusion, one can say that falling, idle talk, curiosity, and ambiguity transform Heidegger's analysis of everyday life into one of the sharpest critiques of the human condition. He shows that man is often lost not in obvious ignorance, but in apparent knowledge; not in absolute silence, but in excessive talk; not in not seeing, but in superficial seeing; not in complete meaninglessness, but in ready-made and public meanings. Inauthenticity means just this: living in a world in which everything appears to have been said, seen, and understood, but Dasein has still not taken over itself. Falling shows that the difficulty of being human is not that we have no world, but that the everyday world can be so familiar and calm that it prevents us from asking the fundamental question about our own Being. Heidegger, by revealing this structure, opens the way for the next step: anxiety as the mood that breaks this calm and calls Dasein from the heart of the "they" toward its own distinctive possibility.
Anxiety: The Rupture from the Everyday World and the Disclosing of the Possibility of Authenticity
After the analysis of falling, idle talk, curiosity, and ambiguity, Heidegger arrives at one of the most important fundamental moods of Dasein: “anxiety” (“Angst”). Anxiety in “Being and Time” is not a normal psychological state, a passing feeling, or an individual disorder; it is an existential mood in which Dasein's fundamental structure is disclosed in a special way. If Dasein's everyday life usually passes in the comfort of the "they," involvement with tasks, repetition of public talk, and absorption in the familiar world, anxiety breaks this familiarity. In anxiety, the world that had previously seemed obvious, reliable, meaningful, and comforting suddenly loses its usual validity. Things are still there, others are still there, equipment, roles, and tasks are still in their places, but the calm and ordinary meaning on which everyday life relied recedes. Dasein in anxiety confronts a world in which it can no longer simply hide.
To understand anxiety, one must first distinguish it from fear. Fear (“Furcht”) is always of something specific in the world. I fear illness, failure, an enemy, an accident, a threat, poverty, the judgment of others, or a definite danger. Fear has an object, a direction, and usually remains within the everyday world. Something in the world threatens me, and I try to avoid it, control it, decide about it, or prepare for it. But anxiety is not like this. Anxiety is not of something specific in the world. In anxiety, one cannot easily say “what” one is anxious about. This lack of object is not psychological vagueness, but shows that anxiety does not arise from a particular being, but from Dasein's very Being-in-the-world. Fear relates to a being in the world; anxiety relates to the worldhood of the world and to Dasein's Being in it.
In anxiety, the world as a whole of familiar meaning recedes. Equipment is no longer as inviting and available as before; roles no longer provide complete shelter; the talk of the "they" no longer comforts; everyday tasks suddenly appear futile or insignificant; and Dasein stands before its own Being. This experience should not be conflated with simple despair or depression. Heidegger is not describing a clinical condition. He wants to show that sometimes a fundamental mood reveals a structure that was concealed in everydayness. In anxiety, Dasein realizes that the everyday world, with all its ready-made meanings, is not the ultimate foundation of its Being. What the "they" say, what custom determines, what social roles provide, and what everyday occupations have covered over is no longer enough. Dasein in anxiety falls out of these coverings.
Heidegger says that in anxiety, what makes Dasein anxious is Dasein's very Being-in-the-world. This sentence is difficult at first glance, but becomes clearer if understood in the light of the preceding analysis. Dasein is always in the world; the world is the horizon of meaning, equipment, others, language, and its possibilities. In everydayness, this world is so familiar that Dasein gets lost in it and understands itself through it. But anxiety shakes this familiarity. The world is neither destroyed nor transformed into a threatening object; rather, it loses its character of being a home. Dasein suddenly realizes that it is in a world, but this Being-in-the-world is no longer calm and obvious. It confronts its own fundamental homelessness; the fact that no public interpretation, no social role, and no everyday occupation can ultimately lift the burden of its Being from its shoulders.
For this reason, anxiety separates Dasein from the "they." In everyday life, the "they" tell Dasein what to do, how to understand, how to live, and how to flee from difficult questions. But in anxiety, the voice of the "they" weakens. Not in the sense that others actually disappear, but in the sense that the calming power of public interpretation diminishes. Dasein can no longer completely hide behind "everyone is like this." Anxiety individualizes him; it brings him back to himself. But this return to self is not a return to a fixed essence, a hidden personality, or a psychological identity. Dasein in anxiety confronts itself as “possibility”. It realizes that its Being is entrusted to it and that no one can take over its Being in its place.
Here the link between anxiety and freedom becomes apparent. In everydayness, Dasein often takes its possibilities from the "they." It sees the paths that the public world has laid before it. But anxiety robs these ready-made paths of their absolute validity. When the everyday world loses its obviousness, Dasein confronts its possibilities more nakedly. This freedom is not arbitrary and light; it is a heavy freedom. Dasein realizes that it cannot completely flee from choice, possibility, and the responsibility of its Being. Anxiety reveals freedom, but not as the excitement of choice, but as helplessness before possibility. Dasein is free because it must be; it must live its possibilities in some way; even if its choice is the flight from choice.
This freedom is linked to “nullity” (“Nichtigkeit”). Anxiety confronts Dasein with the fact that its foundation is not something present, fixed, and certain. Dasein did not create itself, did not choose its beginning, was thrown into the world, and yet must take over its possibilities. It is neither the absolute foundation of itself, nor can it completely surrender the responsibility for its Being to an external foundation. This situation creates a kind of nullity at the heart of Dasein. Dasein exists on the basis of the “non”-being of a certain foundation. It is always between thrownness and projection; it comes from a place it did not choose, and moves toward possibilities it must live in some way. Anxiety reveals this groundlessness not theoretically, but as an existential mood.
For this reason, anxiety can be a path to authenticity. In inauthenticity, Dasein flees from itself and hides itself in the "they," idle talk, curiosity, and ambiguity. Anxiety makes these hiding places unstable. In anxiety, Dasein can no longer fully rely on the public world. It is returned to its own distinctive possibility. This return is not yet full authenticity, but it opens its possibility. Anxiety is like a fissure in everydayness; a fissure through which Dasein can experience itself not merely as a social role, a consumer of public talk, or a member of the "they," but as a possible, thrown, and responsible being. Thus, anxiety for Heidegger is not a purely negative experience. Although it breaks the calm of everydayness, this break can bring Dasein closer to a deeper truth.
Nevertheless, Dasein usually flees from anxiety. The "they" help him transform anxiety into fear. If anxiety is objectless and confronts Dasein with its own Being, fear has a definite object and can be dealt with in an everyday way. The "they" try to explain anxiety, name it, attribute it to a definite cause, cover it with entertainment, or transform it into ordinary worries. This is not always bad; everyday life would be impossible without such returns. But existentially, this flight shows that Dasein does not want to confront its own fundamental helplessness. It prefers to turn anxiety into fear of something definite, because with fear one can do something; but anxiety targets Dasein itself. Anxiety does not say this or that thing is the problem; it says your own Being is the problem.
Here one must clarify an important difference. Heidegger does not psychologize anxiety or say that man should be constantly anxious. Anxiety is a mood that discloses something, not a state to be permanently maintained. Human life needs the everyday world, work, language, others, and relative calm. Dasein cannot always remain in the intensity of fundamental anxiety. But if it never experiences anxiety, if it immediately covers every fissure in everydayness with idle talk, entertainment, ready-made explanations, or occupation, the possibility of authenticity is never opened for it. Anxiety is like a moment when the curtain is pulled aside. The curtain need not remain aside forever, but this pulling aside shows that what Dasein took as its absolute home is not the final home.
Anxiety is directly connected to the concept of “unhomelikeness” (“Unheimlichkeit”). In everydayness, Dasein usually feels at home in its world. Home, language, work, the "they," and habits give it a sense of belonging. But anxiety shows that at bottom, Dasein is never completely at home. This unhomelikeness does not mean not having a physical home, though it can be connected to that. Existential unhomelikeness means that Dasein can never find ultimate calm in the everyday world, because its Being is always an issue, a possibility, and a finitude. It is in the world, but the world cannot completely resolve the question of its Being. Anxiety reveals this strangeness. What was previously completely familiar suddenly becomes strange; and in this becoming strange, Dasein itself becomes more disclosed to itself.
This experience of unhomelikeness can be understood in various forms in human life. Sometimes in the midst of the most ordinary tasks, one suddenly feels that everything has become meaningless; not because things have disappeared, but because one's familiar relation to them has loosened. Sometimes successes that the "they" value no longer seem sufficient. Sometimes the roles with which one defined oneself can no longer answer a deeper question. Sometimes silence, loss, solitude, confrontation with death, or the experience of failure pulls aside a curtain, and one realizes that the everyday world, with all its busyness and certainty, cannot cover the fundamental question of Being. Heidegger understands these moments not as merely psychological events, but as ways in which Dasein's structure is disclosed.
Nevertheless, one must be careful not to simply conflate Heideggerian anxiety with personal experiences. Heidegger does not speak as a psychologist and does not want to classify types of individual anxiety. He is seeking the existential structure of anxiety. Many everyday experiences of anxiety may be linked to psychological, social, economic, or biological factors and require their own analysis and treatment. But anxiety in “Being and Time” is a philosophical concept: the mood in which the worldhood of the world and Dasein's distinctive possibility are disclosed. Thus, one must use this concept precisely. Not every worry, pressure, fear, or restlessness should be understood in the Heideggerian sense of anxiety. Heideggerian anxiety does not arise from this or that thing, but from one's very Being in the world.
In the analysis of anxiety, the concept of "nothing" also has a hidden presence; a presence that Heidegger later makes more explicit in the lecture "What is Metaphysics?" In anxiety, beings are not completely destroyed, but they recede from their everyday meaning. This recession makes possible a kind of experience of nothing. Nothing here is not a being, not a physical void, not simple non-being. Nothing is the disclosedness in which beings can lose their obviousness and become manifest “as” beings. Anxiety places Dasein before this nothing; not to destroy it, but to show that the everyday world is not the final foundation. Thus, anxiety is also a path to philosophical questioning. Philosophy begins with wonder, but for Heidegger, anxiety is also one of the ways philosophy begins; because it breaks the obviousness of the world.
This point shows that anxiety is related to truth. Truth for Heidegger is not just the correctness of a proposition; it is unconcealment and disclosedness. Anxiety, by pulling aside the cover of everydayness, brings Dasein closer to its own unconcealment. In everyday life, Dasein hides itself in roles, tasks, talk, and public judgments. Anxiety pulls aside these coverings and shows that Dasein is at bottom a possible and helpless being. This disclosedness may not be pleasant, but truth is not always comforting. Sometimes truth is accompanied by trembling, because it shows that what Dasein built for its own comfort is not ultimately stable. Anxiety is from this perspective a truth-disclosing mood. Not because it gives new information, but because it transforms Dasein's relation to the world and to itself.
On the other hand, anxiety is closely linked to death, though it is not yet the full confrontation with Being-toward-death. Anxiety separates Dasein from the "they" and returns it to its own distinctive possibility. Death in “Being and Time” also has precisely this role: death is Dasein's distinctive, non-transferable, and ultimate possibility. In anxiety, Dasein realizes that no one can lift the burden of its Being completely from its shoulders. In confronting death, this truth reaches its peak: no one can be my death in my place. Thus, anxiety prepares the ground for the analysis of death. If Dasein remains lost in the "they," it understands death only as a public event; but anxiety separates it from this publicness and opens the possibility of confronting its own distinctive finitude.
At the same time, anxiety cannot by itself guarantee authenticity. Dasein may, after experiencing anxiety, return to the "they" and even hide itself with greater intensity in idle talk, curiosity, and occupation. Anxiety only opens the possibility of authenticity, but Dasein must take over this possibility. For this reason, Heidegger's analysis of anxiety requires concepts such as conscience, existential guilt, and resoluteness. Anxiety separates Dasein from the everyday world; conscience calls it to itself; resoluteness shows the possibility of taking over oneself; and death clarifies the ultimate horizon of this taking-over. Thus, anxiety is one station on the path of the analysis of authenticity, not its end.
One must also pay attention to possible criticisms of this concept. Some critics have said that Heidegger's emphasis on anxiety, death, and the individualization of Dasein can distance him from the social, political, and ethical dimensions of life. If anxiety separates Dasein from the "they," does it not risk reducing authenticity to an individual and non-political experience? Does anxious Dasein, in returning to itself, not forget the other? These criticisms are important. Heidegger opens a path to authenticity through anxiety, but he does not sufficiently show how this authenticity should be linked to responsibility toward others, justice, institutions, and collective action. Thus, the analysis of anxiety must be read with caution. Anxiety can free Dasein from the domination of the "they," but if not supplemented by ethics and politics, it may approach a kind of abstract individualism or dangerous decisionism.
Despite this criticism, the importance of anxiety in “Being and Time” is undeniable. Heidegger shows that man does not reach himself only through theoretical awareness or moral reasoning; sometimes a fundamental mood must transform the world for him. We do not always reach truth through concepts; sometimes truth is revealed to us in a way of Being. Anxiety is one of these ways. In anxiety, Dasein realizes that the everyday world, with all its familiarity, cannot be the final foundation. It realizes that its own Being is an issue. This realization may lead to renewed flight, but it can also be the beginning of thought. Philosophy, in Heidegger's sense, begins with the shaking of obviousness.
Thus, anxiety must be understood as the mood of rupture: rupture from idle talk, rupture from curiosity, rupture from ambiguity, rupture from the comfort of the "they," and rupture from the idea that the everyday world has already answered everything. But this rupture is not for the destruction of the world. After anxiety, Dasein is still in the world, with others, working, speaking, and living. The difference is that the world is no longer the same absolute shelter as before. Dasein can return to the world, but perhaps with a different understanding; an understanding that knows that no public interpretation can take over its Being in its place. Anxiety does not separate Dasein from the world to make it worldless; it separates it from being lost in the world so that the possibility of authentic Being in the world can be opened.
In conclusion, one can say that anxiety is one of the key concepts of “Being and Time”, because the transition from the analysis of inauthenticity to the possibility of authenticity occurs through it. Dasein in everydayness falls into the "they," finds comfort in idle talk, curiosity, and ambiguity, and distances itself from its own distinctive possibility. Anxiety breaks this comfort. In anxiety, the familiar world becomes unfamiliar, the "they" lose their calming power, and Dasein confronts itself as possibility. Anxiety is not afraid of anything specific; it arises from Dasein's very Being-in-the-world. For this reason, anxiety is not psychological weakness, but a truth-disclosing mood. This mood prepares Dasein to understand death, conscience, guilt, and resoluteness as the fundamental structures of authenticity. From here, the path of “Being and Time” moves toward one of its most famous and difficult analyses: Dasein's Being-toward-death.
Being-toward-Death: Finitude, a Distinctive Possibility, and the Disclosing of Authenticity
After the analysis of anxiety, Heidegger arrives at one of the most famous and at the same time most difficult parts of “Being and Time”: the analysis of “Being-toward-death” (“Sein-zum-Tode”). Death here is not a biological topic, not merely an event at the end of life, not a subject for personal grief, and not a theological question about the fate after life. Heidegger analyzes death ontologically; that is, he asks what role death plays in the structure of Dasein's Being. All living beings come to an end, but Dasein is the only being that has a relation to its own end. Man is not merely a being whose life will one day end; he is a being who can understand his end, flee from it, deny it, speak about it, make it public, or take it over as his own distinctive possibility. For this reason, death for Heidegger is not merely a future event; it is a horizon that shapes Dasein's present from the ground up.
In everyday life, death is usually understood within the domain of the "they." The "they" say that people die, death is for everyone, it happens sooner or later, it is a natural part of life, one should not think about it too much, and one should just go on living. These sayings are true in a way, but their public truth can conceal the existential truth of death. When one says "everyone dies," death is transformed into a public and faceless event. In this case, Dasein can distance itself from its own death. Death becomes something that happens to people, to others, to everyone, but has not yet confronted me as my own distinctive possibility. By making death public, the "they" empty it of its existential uniqueness. Dasein in everydayness knows death, but in such a way that it flees from it.
Heidegger analyzes this flight very subtly. Everyday Dasein does not deny death; on the contrary, it speaks about it, sees it, hears news of it, knows the rituals related to it, and knows that no one is exempt from it. But this public knowing is a way of not knowing existentially. Dasein knows that "one dies," but this knowing is still not a confrontation with the truth that "I must understand my death as my own distinctive possibility." In everydayness, death is always postponed. The "they" say death will come, but not yet; it is for everyone, but still distant; it is natural, so it should not shake the foundation of life. This "not yet" is the structure of the everyday flight from death. Dasein accepts death, but keeps it at a comfortable distance.
But death in Heidegger's analysis is Dasein's distinctive, certain, unsurpassable, and non-transferable possibility. First, death is a “possibility”, not just an event. This formulation seems strange at first, because we usually understand possibility as something that can be realized, chosen, or used. But death is a possibility that makes all other possibilities limited and final. Death is the possibility of the impossibility of all possibilities. As long as Dasein exists, it lives in possibilities; it can work, choose, change, return, learn, fail, and begin again. But death is the horizon in which all these possibilities become finite. Death is not one possibility alongside others; it is the ultimate possibility that illuminates the whole structure of Dasein's possibility.
Second, death is Dasein's “distinctive” possibility. No one can be my death in my place. Others can be beside me, speak about me, grieve for me, or remember me, but my death is ultimately a possibility that belongs to me alone. This point separates Dasein from the "they." In many affairs of life, one can rely on others, learn from them, share with them, or even entrust tasks to them. But death is not transferable. I cannot surrender my death to another. This non-transferability returns Dasein to its own existential uniqueness. In death, the "in each case mine" character of Dasein becomes most intensely apparent. Death pulls Dasein out of the publicness of the "they" and confronts it with its own distinctive possibility.
Third, death is “certain”, but its time and manner remain “indeterminate” for Dasein. Dasein knows that death is its ultimate possibility, but it cannot place it in a complete and certain plan. This indeterminacy transforms death from a manageable event into an existential horizon. If death were merely an event with a completely known date and form, Dasein might be able to arrange it like a task among other tasks. But death is always possible, without its time being at Dasein's disposal. This constant and indeterminate possibility shows that Dasein always lives in the shadow of finitude. Death is not only at the end of life; from the beginning, it shapes life's possibilities. Because Dasein dies, its possibilities acquire weight, urgency, and uniqueness.
Fourth, death is “unsurpassable”. Dasein can overcome many of its possibilities, set them aside, replace them, or reinterpret them. But it cannot surpass death. Death is the ultimate limit of its possibilities. This limit is not added to life from outside; it shapes the structure of life from within. Dasein is a finite being, and this finitude is not a simple defect, but the condition for the possibility of authenticity. If Dasein's life were infinite, endless, and without pressure, possibilities would lose their urgency and seriousness. It is death that shows that life cannot remain forever in postponement, idle talk, curiosity, and ambiguity. Finitude compels Dasein to understand that it cannot surrender its Being to the "they" indefinitely.
From here emerges the concept of “anticipation of death” (“Vorlaufen zum Tode”). Anticipation of death does not mean hastening toward the end, a morbid desire for death, or leaving life. This is a very important point. Heidegger speaks of an existential attitude, not of risky behavior or a negation of life. Anticipation means that Dasein understands death as its own ultimate and distinctive possibility and allows this understanding to transform its way of living. Authentic Dasein does not banish death to a distant and public future; it understands it as the horizon of its own finitude. It knows that its possibilities are not endless and that no one can take over its Being in its place. This awareness does not diminish life; on the contrary, it makes it more serious and authentic.
In anticipation of death, Dasein is freed from the domination of the "they," because death is something the "they" cannot take from it. The "they" can speak about death, make it public, comfort, or conceal it, but they cannot be Dasein's own death in its place. When Dasein understands death as its own possibility, it realizes that its life must also be its own. If my death is not transferable, my life also cannot be completely surrendered to the "they." This link between death and authenticity is one of the most radical moments of “Being and Time”. Death does not make Dasein individualistic in a superficial sense; it pulls it out of the anonymity of the "they" so that it can take over its own Being.
But this taking-over does not mean isolation. Dasein is still with others, in the world, has language, works, and lives in history. The difference is that it no longer wants to take its possibility entirely from the "they." It can be with others, but not as dissolved in them. It can speak, but not in idle talk. It can see, but not in superficial curiosity. It can work, but not in such a way that occupation covers its entire Being. The authentic confrontation with death does not remove Dasein from the world; it returns it to the world in a more authentic way. This return is the return of one who knows that the everyday world is not the ultimate foundation and that the "they" cannot lift the burden of its Being in its place.
Death also illuminates the “unity” of Dasein's life. Human life is not a collection of scattered moments. Dasein always understands itself from the future, and death is the ultimate horizon of its future. This does not mean that Dasein should constantly think about the end, but that its whole life acquires meaning within the horizon of finitude. Decisions, possibilities, commitments, failures, and returns are all understood in the light of the fact that Dasein has limited time and cannot live all possibilities at once. Choosing one possibility means setting aside others. Dasein always lives in a kind of limitation. Death reveals this limitation fundamentally. Authenticity means accepting this limitation, not fleeing from it into the fantasy of endless possibilities or taking refuge in the public comfort of the "they."
From this perspective, death is directly linked to temporality. Dasein is futural, because it always moves toward its possibilities. But the authentic future of Dasein is not merely a set of plans, goals, and possible successes; the authentic future is understood in the horizon of death. Death shows that Dasein's future is not unlimited and its possibilities must be understood on the basis of finitude. The past also acquires new meaning in the light of death, because Dasein realizes that it cannot erase its past, but can take it over in a more authentic projection. The present also emerges from superficial occupation and becomes a moment for taking over possibility. Thus, death is a way to a deeper understanding of Dasein's temporality.
Nevertheless, Heidegger does not analyze death in the context of grief, loss, or the relation to the death of others. His focus is on Dasein's own death, because he wants to reveal Dasein's distinctive and non-transferable possibility of Being. This focus is understandable for the project of “Being and Time”, but it also has limitations. Human life is not only related to one's own death; the death of others also transforms our world. Loss, mourning, memory, love, dependence, and responsibility toward the lives of others are dimensions that Heidegger's analysis does not sufficiently address. He analyzes death from the perspective of Dasein's authenticity, but he shows less how death shakes the network of Being-with and the shared world. Thus, his analysis is deep but one-sided. To complete it, one must also attend to ethics, affect, mourning, care, and the relation to the other.
Despite this limitation, Heidegger's achievement remains great. He shows that death is not merely the last event of life; it is a structure that shapes all of life from within. Man can live for years without thinking seriously about death, but this thoughtlessness does not mean that death is absent from the structure of his life. Death is present in every choice, every postponement, every fear, every hope, and every possibility. Because we are finite, we must choose. Because we cannot be everything, we must choose a path. Because our time is not endless, life has weight. Death from this perspective is not the end of meaning, but the condition for meaning to become serious. If Dasein understands death properly, it can understand life not as an accumulation of moments, but as an authentic possibility of Being.
Against the everyday understanding of death, which makes it a public and distant event, Heidegger places the authentic understanding of death. In inauthentic understanding, death is something that will happen "one day" and must now be put aside. In authentic understanding, death is a horizon that clarifies my possibilities right now. This authentic understanding, of course, does not mean constant anxiety or morbid obsession with the end. It means living in awareness of finitude. Authentic Dasein does not understand death to flee from life, but to take over life. Death brings it out of dispersion, because it shows that its possibilities are limited, unique, and non-transferable. It cannot remain in postponement forever. This understanding gives life intensity, focus, and responsibility.
Here one must note the relation between death and conscience. Death confronts Dasein with its own distinctive possibility, but there still needs to be a force that calls it out of its fall into the "they." This force, in Heidegger's analysis, is the call of conscience. Conscience calls Dasein out of the idle talk of the "they" and tells it that it must take over itself. But without death, conscience lacks its ultimate depth, because what returns Dasein to itself is ultimately its finitude. On the other hand, death without conscience may only become an abstract meditation on the end. In the structure of authenticity, anxiety, death, conscience, guilt, and resoluteness are interconnected. Each reveals part of the path of Dasein's emergence from inauthentic everydayness and return to its own distinctive possibility.
On another level, the analysis of death shows that man for Heidegger is a fundamentally “finite” being. This finitude is not merely biological limitation; it is the ontological structure of Dasein. Dasein is not from the start complete and finished. It must construct itself in its possibilities, but every construction occurs within the horizon of limitation. It is free, but its freedom is not boundless. It understands, but its understanding is historical and limited. It chooses, but it cannot choose all possibilities at once. It is with others, but no one can be in its place. It has a future, but its future is in the horizon of death. Thus, finitude is not an external defect, but the very condition of Dasein. With this analysis, Heidegger moves philosophy from the search for absolute and infinite foundations toward the understanding of the existential limitation of man.
This view stands against many forms of traditional metaphysics that understood the truth of man in relation to the eternal, universal reason, the immortal soul, or the self-grounding subject. Heidegger does not want to make a theological judgment about the fate after death; he remains at the ontological level of Dasein. At this level, what matters is that Dasein understands itself in the horizon of death. This understanding is neither a denial of religion nor its proof; it is a pre-religious and pre-theoretical analysis of the human structure. Even someone who has a religious belief in the continuation of life, as Dasein, still confronts finitude, choice, a distinctive possibility, and the non-transferability of its Being. Thus, Heidegger's analysis of death should be kept separate from belief-based discussions about the afterlife. He speaks of the existential meaning of death for Dasein's life.
An important criticism that can be leveled at Heidegger is that his focus on death may downplay birth, beginning, natality, and the possibility of newness. Hannah Arendt later, against Heidegger's emphasis on death, emphasized “natality” and the capacity to begin. For Arendt, man is not merely a being-toward-death; he is a being who, with his birth, brings the possibility of new beginning into the world. This criticism is important, because Heidegger's analysis of authenticity focuses too much on finitude, death, and the individualization of Dasein, and less on action, birth, politics, and shared beginning. Nevertheless, this criticism does not invalidate Heidegger's analysis; it shows that death must be understood alongside birth, finitude alongside beginning, and individual authenticity alongside shared action. Man is both toward death and born from natality and capable of beginning.
One might also ask whether Heidegger's emphasis on death risks individualizing authenticity too much. Because death is non-transferable, Dasein in confronting it returns to itself. But can this return lead to indifference toward others? The precise answer is that in “Being and Time” itself, Being-with is never eliminated, but the analysis of death mostly places Dasein in its own uniqueness. Thus, to prevent existential individualism, the analysis of death must be supplemented by the analysis of responsibility toward the other. My death is my own distinctive possibility, but my life occurs in a world with others. Authenticity, if it cannot lead to a more responsible relation to others, remains incomplete. This is one of the important limitations of “Being and Time”.
Nevertheless, the analysis of Being-toward-death remains one of the most powerful parts of contemporary philosophy. Heidegger lifts death from the level of a distant event or a merely emotional subject and shows how finitude shapes the structure of life. He teaches us that flight from death is not just flight from the end; it is flight from life itself. Because Dasein's life is only understood as a distinctive possibility within the horizon of its finitude. If Dasein surrenders death to the "they," it has also surrendered life to the "they." But if it understands death as its own non-transferable possibility, then it can bring life out of public repetition and transform it into an authentic possibility. This understanding does not make death the enemy of life; it makes death the horizon of life becoming serious.
In conclusion, one can say that Being-toward-death is the point at which the analysis of Dasein reaches its deepest level of finitude. Dasein is in the world, with others, falls in the "they," flees from itself in idle talk, curiosity, and ambiguity, but anxiety pulls it out of this comfort and death confronts it with its own distinctive and non-transferable possibility. Death is the possibility of the impossibility of all possibilities; but precisely for this reason, it illuminates all of Dasein's possibilities. Authentic Dasein is not one who flees the world or negates life; it is one who, in the horizon of death, takes over its life as a finite possibility. This taking-over opens the way for the next stage of Heidegger's analysis: the call of conscience, existential guilt, and resoluteness; structures that show how Dasein, from the heart of finitude, is called to its own authentic possibility.
Conscience, Existential Guilt, and Resoluteness: Dasein's Call to Itself
After the analysis of Being-toward-death, Heidegger arrives at a decisive question: how can Dasein return from its lostness in the "they" toward its own authentic possibility? Anxiety robs the everyday world of its obviousness, and death confronts Dasein with its own distinctive and non-transferable possibility, but one still needs to show how this return actually occurs within Dasein itself. Inauthentic Dasein is scattered in idle talk, curiosity, ambiguity, and public interpretations. It takes itself from the "they" and hides the responsibility for its Being in everyday comfort. But in the depth of this same Dasein, there is a possibility that calls it out of this dispersion. Heidegger explains this possibility through the concept of “conscience” (“Gewissen”). Conscience in “Being and Time” is not a moral faculty in the ordinary sense, not the voice of God in the theological sense, not a set of internalized social norms, and not a psychological feeling of remorse. Conscience is an existential structure; it is a “call” that summons Dasein from its lostness in the "they" toward its own possibility.
To understand the meaning of conscience for Heidegger, one must separate it from ordinary understandings. In everyday life, conscience is usually understood as an inner voice that reproaches one after doing something wrong, or warns one before doing something wrong. In the ethical and religious tradition, conscience is often linked to good and evil, duty, sin, moral responsibility, or inner judgment. Heidegger does not entirely negate these meanings, but he believes they are grounded in something deeper. Prior to conscience telling us to do or not to do this or that, prior to reproaching us for a specific error, and prior to relating to specific moral norms, conscience calls Dasein to its own possibility of Being. The call of conscience, at its core, is not about a specific behavior, but about Dasein's Being. This call pulls Dasein out of the noise of the "they" and makes it aware that its Being is entrusted to itself.
The call of conscience in Heidegger's analysis has a peculiar feature: it “says nothing”. Or more precisely, it has no propositional content. Conscience does not give Dasein a list of commands, instructions, or recommendations. It does not say do this, choose that, obey this law. The call of conscience, more than speaking, “summons”. This silence is not a sign of emptiness; it is a sign of depth. The language of the "they" is full of talk, explanation, justification, judgment, and interpretation. The "they" always have something to say. But the call of conscience is not of the nature of idle talk. Conscience calls Dasein in a fundamental silence; a silence that cuts through public talk. In this call, Dasein is confronted not with new information, but with its own Being. Conscience does not teach; it awakens.
But who calls in conscience, and who is called? Heidegger's answer is complex: Dasein itself calls itself. But this "self" should not be understood as the psychological ego or the conscious will. In everydayness, Dasein has lost itself in the "they"; but its authentic possibility has not been completely destroyed. The call of conscience arises from the depth of this authentic possibility and addresses fallen Dasein. Thus, Dasein is both the caller and the one called. On one hand, it is lost in the "they" and must be called; on the other hand, what calls it is not something outside it, but its own authentic possibility. Conscience shows that even in inauthenticity, Dasein is not completely separated from itself. The lost self can still call Dasein out of its lostness.
This structure distinguishes conscience from social morality. In social morality, it is usually society, law, custom, or the value system that tells the individual what to do. But Heideggerian conscience precisely pulls Dasein out of the domination of the "they." If conscience were merely the voice of society within the individual, it could not free Dasein from the "they." The call of conscience is opposed to the public voice; not in the sense that it always contradicts public laws and ethics, but in the sense that it compels Dasein to take over its relation to its own Being anew. Authentic Dasein may ultimately do the same thing as others, but the difference is in the “way” of Being. It no longer acts simply because the "they" say so or do so; it takes over its own possibility in its own situation.
To what does the call of conscience summon Dasein? Heidegger answers: to “guilt” (“Schuld”). But this word must also be understood carefully. “Schuld” in German means both guilt, debt, and responsibility. In “Being and Time”, guilt prior to any moral or legal meaning is an existential structure. Heidegger does not mean to say that Dasein has necessarily committed a specific sin or is always morally culpable. He wants to show that Dasein, in the ground of its Being, has a kind of indebtedness and lack. Dasein did not create itself, did not choose its beginning, was thrown into the world, and yet must take over its possibilities. It is always in a situation that has already begun and in which it must choose. Every choice also means setting aside other possibilities. Thus, Dasein always lives on the basis of a kind of "not"; a kind of non-being, limitation, and incompleteness at the heart of its Being.
Existential guilt means that Dasein is not the ground of itself, but must make itself the ground of projecting its possibilities. This sentence is difficult at first glance, but becomes clearer if understood with thrownness and projection. Dasein is thrown into the world; that is, it did not choose the initial conditions of its Being. It received its language, history, body, family, time of birth, many of its possibilities and limitations. On the other hand, Dasein is not merely a product of these givens; it has possibilities, projects, chooses, and opens itself toward the future. Thus, it is in a situation where it is neither the absolute ground of itself nor without responsibility. This situation is its existential guilt. It must always, from the heart of what it did not choose, take over possibilities that have consequences. It is indebted, because its Being is not an unquestioned and irresponsible gift; its Being is from the start involved in the responsibility of possibility.
This existential guilt is different from moral fault, but it is the condition for the possibility of ethics. Only a being whose Being is entrusted to itself and who can take over its possibilities can be morally responsible. If Dasein were merely a natural object, fault and responsibility would have no meaning. If Dasein were the absolute ground of itself and had no limitations, responsibility would also lose its human meaning. Responsibility arises precisely in the gap between thrownness and freedom. I did not choose all my conditions, but I cannot completely exempt myself from responsibility for the way I live in these conditions. Existential guilt means that I am always already in a situation that I must take over in some way. This taking-over is the basis of the possibility of authenticity.
The call of conscience summons Dasein to this guilt. But this call is not reproachful in the ordinary sense. Conscience does not say you have committed this or that error; it says you have fled from yourself, you have surrendered your Being to the "they," you must take over your own possibility. Thus, conscience returns Dasein not only to the past, but to the future. In ordinary remorse, one looks at what one has done and may feel guilt. In existential conscience, Dasein is called to its own possibility. This call does not mean returning to a ready-made essence; it means openness to authentic possibility. Conscience pulls Dasein out of idle talk and ambiguity and places it before a silence in which it must decide for itself how to be.
But how does Dasein respond to the call of conscience? Heidegger's answer is the concept of “resoluteness” (“Entschlossenheit”). Resoluteness is one of the most difficult and controversial concepts of “Being and Time”. At first glance, this word may suggest firm decision, strong will, or heroic choice. But in Heidegger, resoluteness is more openness than voluntarism. The word “Entschlossenheit” comes from a root related to opening and being opened. Resoluteness means that Dasein opens itself to its own possibility and emerges from lostness in the "they." It hears the call of conscience, accepts its existential guilt, and is prepared to take over its own possibility in its thrown situation.
Resoluteness does not mean having a specific plan or choosing a definite content. Heidegger deliberately does not say what exactly authentic Dasein should do. This silence is on one hand consistent with the logic of his ontology, because he does not want to write a normative ethics or practical instruction. On the other hand, this same silence can be dangerous and problematic, because resoluteness, if separated from ethical criteria, rational dialogue, and responsibility toward others, may degenerate into empty decisionism. In “Being and Time” itself, resoluteness means more a way of Being than the content of a decision. Resolute Dasein is one who has emerged from the "they," accepted its guilt, and takes over its own possibility in its situation. But how this possibility should be realized in relation to justice, the other, and politics is not sufficiently clarified in Heidegger's text.
Nevertheless, if resoluteness is properly understood, it should not be conflated with arbitrariness or voluntarism. Resolute Dasein does not do whatever it wants. It is resolute precisely because it accepts its thrownness and guilt. It knows that it does not decide in a vacuum; it is placed in a historical, linguistic, social, and finite world. Resoluteness means openness to the situation, not denial of the situation. Resolute Dasein does not flee the world; it returns to the world, but not as one dissolved in the "they." It lives in the same tasks, relations, language, and history, but now it takes over its own possibility within them. Thus, resoluteness is not an exit from the world, but a more authentic way of Being-in-the-world.
This point becomes important in the concept of the “situation” (“Situation”). Inauthentic Dasein is scattered in everyday situations; it is occupied with this task and that, this talk and that, this role and that. But resolute Dasein “sees” its situation. The situation is the specific existential position in which Dasein must take over its own possibility. This situation is not merely a set of external data; it is the horizon in which Dasein's authentic possibility is disclosed. Resoluteness makes Dasein transparent to its situation. It is no longer floating in public ambiguity, but can see what, now, in this world, with this past, with these possibilities and limitations, is asked of it. Of course, Heidegger does not express this "being asked" in the language of normative ethics, but in the language of the existential call.
Resoluteness is also linked to death. Heidegger ultimately speaks of “anticipatory resoluteness” (“vorlaufende Entschlossenheit”); that is, resoluteness that understands itself in the horizon of Being-toward-death. Dasein can only authentically take over its own possibility when it has understood death as its own distinctive and non-transferable possibility. Death separates Dasein from the "they"; conscience calls it; guilt shows that its Being is based on incompleteness and indebtedness; and resoluteness provides the possibility of responding to this call. These concepts are not separate from each other. They form the single structure of authenticity. Authenticity means that Dasein, in anxiety, death, conscience, and guilt, pulls itself out of lostness in the "they" and takes over its own possibility in finite temporality.
But one must note that authenticity for Heidegger does not mean moral perfection, inner purity, or attaining a fixed identity. Authentic Dasein is still finite, thrown, fallible, and in the world. Authenticity is not a permanent state or possession to be acquired once and preserved forever. Dasein can always fall back into the "they." Thus, authenticity is more a way of living than a final position. Authentic Dasein is not one who has been freed from inauthenticity forever; it is one who recognizes its inauthenticity and takes over the possibility of returning to itself. For this reason, resoluteness is accompanied by existential humility. Resolute Dasein knows that it is not the absolute ground, knows that it is based on existential guilt, and knows that it lives in the horizon of death.
Here one can see the relation between resoluteness and freedom. Freedom for Heidegger is not arbitrary choice among options. Freedom means openness to one's own possibility within thrownness. Dasein is free not because it can do whatever it wants, but because it must take over its Being in some way. This freedom is heavy, because no one can take it from it. The "they" can give ready-made paths, but cannot be in its place. Resoluteness is the acceptance of this heavy freedom. Freedom in this sense is not liberation from limitations, but responsible living within limitations. Dasein is free because it is finite; because not everything is possible, choice has meaning. Because death exists, possibilities are serious. Because thrownness exists, taking-over matters.
Nevertheless, this very concept of resoluteness has been the subject of serious criticism. Some critics have said that Heidegger, by emphasizing decision, call, death, and authenticity, but without providing clear ethical and political criteria, opens the way for decisionism. If what matters is that Dasein resolutely chooses its possibility, what guarantees that this possibility is ethical, just, or responsible? Is it not possible that an individual or a group might justify a dangerous decision with the language of authenticity, destiny, and resoluteness? This criticism, especially in light of Heidegger's own political history, is very important. In “Being and Time” itself, resoluteness is still a largely existential concept, but its ambiguity can provide a basis for misuse. Thus, a responsible reading must supplement resoluteness with an ethics of the other, public dialogue, historical responsibility, and a critique of power.
On the other hand, one should not, because of this danger, discard the entire concept of resoluteness. Resoluteness is a profound response to the problem of human dispersion in the modern world. Inauthentic Dasein is scattered among thousands of voices, roles, desires, news, images, and superficial possibilities. It is everywhere and nowhere; it sees everything and takes over little; it speaks about everything and authentically encounters less. Resoluteness, against this dispersion, calls Dasein to existential concentration. This concentration is not isolation, not the violence of will, but the ability to hear a call that comes from silence. Resolute Dasein can, from the noise of the "they," hear its own possibility. This idea, if supplemented ethically and politically, remains valuable.
Conscience also acquires new meaning in today's world. In a world where public voices, media, networks, advertisements, and collective judgments constantly surround Dasein, hearing a call that says nothing but summons is more difficult and perhaps more necessary. Heideggerian conscience calls us to a silence in which we can ask ourselves whether what we say, want, and do is truly our own or merely a repetition of the "they." This question is important not only in individual life, but also in intellectual, academic, media, and political life. One may speak, write, analyze, and take positions for years, but never hear the call of conscience; because one has always been full of the voice of the "they." Conscience means the possibility of a silence in which Dasein can no longer completely hide behind public voices.
At the same time, one must be careful that Heideggerian conscience does not become a kind of inner self-sufficiency. If it is said that conscience calls from within Dasein, one might suppose that any inner feeling or personal decision can be the ultimate criterion. But Heidegger does not mean this. Conscience is not private feeling nor individual taste. Conscience calls Dasein to its guilt and thrownness; that is, it makes it aware of its limitation, responsibility, and incompleteness. Thus, authentic conscience should make Dasein more humble and responsible, not more self-willed. Nevertheless, to prevent slippage into self-sufficiency, this conscience must be linked to responsiveness to the other and the shared world. The call of conscience should not be an excuse for indifference to the voice of others; rather, it should enable Dasein to hear the voice of others not at the level of the "they," but in the depth of responsibility.
Now one can see more clearly the place of existential guilt. Guilt for Heidegger does not mean pessimism about man. He does not say that man is essentially corrupt or should be ashamed of his Being. Guilt means that Dasein is built on the basis of incompleteness and non-being. It is never the complete owner of itself. It is always too late; in a world that began before it, in a language that was spoken before it, in a history that flowed before it, and in a body that was given to it without its initial choice. But this same Dasein must choose, respond, open some possibilities, and close others. It cannot escape its incompleteness. Resoluteness means accepting this incompleteness, not trying to become an absolute and rootless subject. Thus, existential guilt is the basis of Dasein's humility.
In relation to temporality, these concepts acquire special importance. Conscience calls Dasein from its inauthentic and fallen past, but this call opens it to the future of authentic possibility. Guilt shows that Dasein has a thrown past that it cannot erase. Resoluteness shows that Dasein can take over this past in a future-oriented projection. Death clarifies the ultimate horizon of the future. Thus, the whole structure of conscience, guilt, and resoluteness is from the start temporal. Authentic Dasein does not deny its past, is not scattered in the present, and does not reduce the future to a set of plans. It returns from its death-aware future to its thrown past and takes over its situation in the present. This is the temporal Being of authenticity.
In conclusion, one can say that conscience, guilt, and resoluteness are a decisive stage in the analysis of “Being and Time”. Dasein in everydayness falls into the "they," but anxiety breaks the comfort of the "they" and death reveals Dasein's distinctive possibility. Conscience in the midst of this calls Dasein to itself. This silent call makes it aware of its existential guilt: that it is not the absolute ground of itself, is thrown into the world, and yet must take over its own possibility. The authentic response to this call is resoluteness; Dasein's responsible openness to its own possibility in its thrown and finite situation. But this resoluteness must be understood with caution. If separated from ethics, the other, and the critique of power, it risks decisionism; but if properly understood and supplemented, it is one of the most powerful philosophical responses to human lostness in the everyday world.
Thus, Heidegger shows that authenticity is not achieved through theoretical instruction, psychological isolation, leaving the world, or obeying ready-made commands. Authenticity begins with hearing a call that returns Dasein from the noise of the "they" to the silence of its own possibility. Authentic Dasein is one who understands its own death, accepts its guilt, hears conscience, and in resoluteness takes over its situation. This path does not separate Dasein from the world; it returns it to the world in a more authentic way. But to understand the ultimate foundation of this return, one must reach a concept that unites all previous structures: “care”. Care will show that Dasein in all these analyses is a being whose Being is an issue for it; a being that projects from the future toward its possibilities, comes from a thrown past, and is engaged in the present with the world and others.
Care: The Structural Unity of Dasein
In the course of “Being and Time”, after the analyses of worldhood, Being-with, the "they," falling, anxiety, death, conscience, guilt, and resoluteness, Heidegger arrives at a concept that seeks to show the unity of all these structures: “care” (“Sorge”). Care is one of the most fundamental concepts of “Being and Time”; perhaps one could say that if Dasein is the name for the being whose Being is an issue for itself, care is the name for the structure of this very issue. Dasein is not a being that first simply exists and then sometimes develops an interest, concern, or attention toward things. Dasein is, from the ground up, a caring being; that is, its Being is an issue for it. It cannot cut off its relation to its Being. Even indifference, flight, entertainment, falling into the "they," and self-forgetfulness are forms of having a relation to one's own Being. Care means that Dasein is always in some way involved with its own Being, its world, its possibilities, and others.
It must be clear from the start that care for Heidegger does not mean psychological worry, everyday anxiety, or limited ethical concern. In ordinary language, when we say someone cares, we might mean they are worried about something, they care about someone, they fear a danger, or they are looking after a task. These meanings can relate to care, but Heidegger's “Sorge” is much more fundamental. Care is the existential structure of Dasein; that is, the very way Dasein is in its essence. Being human means that my Being is not a matter of indifference to me. I am not in the world like a stone or a present object; I am always confronted with possibilities, I come from a past, I am engaged in a present, a future is opened before me, and my relation to myself, others, and the world is always an issue. Care is the name for this fundamental engagement.
Heidegger expresses the structure of care with a rather complex formula: “being-already-ahead-of-itself-in-a-world-and-alongside-beings”. This formula is difficult at first glance, but if connected to the preceding analyses, its meaning becomes clear. Dasein is always "ahead of itself," because it lives with its possibilities. It is never merely what it actually is now; it is always projected toward what it can be. Dasein is futural, it projects, it expects, decides, flees, hopes, and pursues possibilities. This being-ahead shows the futural dimension of care. Dasein is always ahead of itself, because its Being is possibility.
But Dasein is at the same time "in a world." It does not choose its possibilities in a vacuum. It is thrown into a world; a world of language, history, body, family, equipment, institutions, traditions, others, and limitations. This is Dasein's thrownness. It did not choose its beginning, but it must, in a world that has already begun, project itself toward its possibilities. Care thus is not just freedom; freedom is within facticity. Dasein cannot pull itself out of the world and decide from an absolute point. Every decision, every possibility, and every projection occurs within a pre-given horizon. This dimension shows the past-oriented character of care: Dasein is always already in a world, comes from a past, and confronts realities given to it.
Third, Dasein is "alongside beings"; that is, in the world it deals with things, equipment, tasks, and others. It is not merely projected toward the future and not merely comes from a past; in the present, it is engaged with the world. Dasein works, speaks, uses equipment, fears something, wants something, helps another, flees from another, builds a house, reads a book, walks, and is occupied in everyday tasks. This dimension shows the present-oriented character of care: Dasein in the present is engaged with beings and others. Thus, care is from the start a “temporal” structure: future, past, and present are connected in it. Dasein is ahead-of-itself toward its possibilities, already in a thrown world, and now engaged alongside beings.
From here one can understand why care is the structural unity of Dasein. Earlier we saw that Dasein has understanding, is attuned, is in the world, is with others, falls, is anxious, is toward death, hears conscience, and in resoluteness takes over its possibility. If these are understood separately, they may appear as a collection of scattered states or properties. But Heidegger wants to show that all these structures are rooted in one whole. Dasein understands because it cares about its possibilities. Dasein is attuned because it has found itself in a world where its Being is an issue for it. Dasein is with others because its world is the shared world of cares. Dasein falls because it can flee from the burden of care and hide itself in the "they." Dasein becomes anxious because care confronts it with the groundlessness of its Being. Dasein is toward death because its ultimate possibility shapes all its possibilities. Conscience calls because Dasein must make care its own. Resoluteness is the authentic response to the structure of care.
Care also shows that Dasein is never a neutral and indifferent being. The world for Dasein is not merely a set of data; the world is always “significant” for it. This significance is the foundation of human understanding. I understand something because I live in a world where things relate to my possibilities, needs, goals, dangers, hopes, and relations. If nothing were an issue for me, no world in Heidegger's sense would be disclosed. Even theoretical knowledge is based on a kind of care. The scientist cares about truth, the problem, the method, discovery, precision, or the scientific tradition. The philosopher cares about the question. The artist cares about the disclosure of the world in the work. Thus, care is not merely personal feeling; it is the foundation of any human relation to the world. Dasein has a world because it cares.
This point is another critique of the modern picture of the neutral subject. In modern philosophy and science, the ideal of knowledge has sometimes been that man should be a neutral, disinterested, detached observer of things. Heidegger does not say that methodological neutrality is always without value, but he shows that such neutrality is never the primary beginning. Even scientific neutrality is a specific way of caring; caring for precision, control, replicability, or theoretical truth. Man never steps out of care entirely. He can set aside some personal interests, but setting aside itself occurs within a horizon of importance and purpose. Thus, Dasein is never an empty, directionless mind. It is always in a world where something is at issue for it. Care is the name for this "being-at-issue."
Care is directly related to the concept of possibility. Dasein is a being that is always ahead of itself in its possibilities. These possibilities are not just everyday conscious choices; they are ways of Being. I can lose myself in the "they," flee from myself, be called to my authentic possibility, take over my past, confront my death, live more responsibly in the world. Care means that Dasein is always in relation to such possibilities. It is never merely its actual present self. If one defines oneself only by what one is now, one has not understood Dasein's structure. Dasein is always more than itself, because it still has possibility. But this being-more is not unlimited and infinite; it is limited by thrownness and death. Care means finite possibility.
Thrownness has a decisive place in the structure of care. Dasein finds itself in a world it did not choose. It begins with a specific body, a specific language, a specific history and culture, a specific family and conditions, and a specific time. But this givenness does not mean complete determinism. Dasein creates possibilities for itself from these givens or flees from them. Care occurs precisely in this tension between givenness and possibility. If Dasein were completely free and rootless, care would lose its human meaning; if it were completely determined and closed, again care would have no meaning. Dasein cares because it is neither the absolute master of its possibilities nor a helpless object. It is in the middle: thrown, but possible; limited, but open; indebted to the past, but facing the future.
From here one can understand why existential guilt is related to care. In care, Dasein is always based on incompleteness and non-being. It cannot have all possibilities; every choice means setting aside other choices. It is not the absolute ground of itself; it comes from a past it did not choose. It is open to a future, but this future is limited by death. Thus, care is always accompanied by a kind of indebtedness and non-being. Dasein must be, but its Being is never complete, transparent, and without issue. It must take over itself, but the self it takes over is already placed in world, history, and limitation. Existential guilt expresses this negative structure at the heart of care. Dasein cares because its Being is never a complete given free from the need for taking-over.
Care also clarifies Dasein's relation to others. In the section on Being-with, we saw that Dasein is from the start with others. Now one can say that this Being-with is also placed within the structure of care. Dasein is not only “concerned” with things; it is also “solicitous” toward other Daseins. Heidegger distinguishes between “Besorgen”, that is, dealing with things and equipment, and “Fürsorge”, that is, solicitude or care toward others. Both are within the horizon of care. I work with equipment because I am in a world of possibilities; I live with others because my world is a shared world. Solicitude toward the other can be inauthentic, if it takes away the other's possibility and makes them dependent. It can be more authentic, if it returns the other to their own possibility. Thus, care is not only my relation to myself; it is also my relation to the world and others. Because Dasein cares, it can be responsible, irresponsible, caring, dominating, companionable, or indifferent.
Nevertheless, one must note that Heidegger does not transform care into an ethics of care. This is one of his important limitations. Care for him is an ontological structure, not a moral theory about caring for the other. He shows that Dasein is from the ground up engaged and caring, but he does not clearly explain how this care should be transformed into justice, compassion, social care, rights, political responsibility, or an ethics of the other. Thus, the concept of care in “Being and Time” is both very powerful and incomplete. Powerful, because it shows that man is never a neutral and unrelated being. Incomplete, because from this existential structure one cannot directly derive ethics and politics. To do this, one must supplement Heidegger with Levinas, Arendt, the ethics of care, theories of justice, and political philosophy.
Care also clarifies Dasein's relation to truth. Truth for Heidegger is not just the correctness of a proposition, but disclosedness and unconcealment. Dasein is disclosed because it cares. It deals with beings, understands them, uses them, speaks about them, and is engaged with them. This disclosedness is not indifferent; it always occurs within a horizon of significance and possibility. Things become manifest for Dasein because they are in a world that has meaning for it. If there were no care and significance, nothing could be disclosed “as” something for Dasein. Thus, care is also the condition for the possibility of truth. Of course, this same care can fall and conceal truth. Because Dasein cares, it can get lost in idle talk, curiosity, and ambiguity. Thus, care is both the possibility of disclosedness and the possibility of concealment.
Here once again the fundamental duality of Dasein becomes apparent. Care can be inauthentic or authentic. In inauthentic care, Dasein hides itself in occupations, the "they," and public interpretations. It still cares, but it has not made care its own. It is concerned with tasks, roles, successes, the opinion of others, everyday security, and public possibilities, but in these concerns it flees from the fundamental question of its Being. In authentic care, Dasein takes over its care in the horizon of death, conscience, guilt, and resoluteness. It is still in the world, but the world is no longer a complete cover over its Being. It is still with others, but not dissolved in the "they." It still works, but does not completely surrender itself to occupations. Authenticity means that Dasein's care is returned to itself and emerges from the state of public dispersion.
Care also shows that Dasein is always “Being”, not just having properties. An object may have color, weight, size, and location, but Dasein is not an object. Dasein “lives” its Being. Care is the name for this living of Being. Dasein is not only having a future; it is “toward” a future. Not only having a past; it comes from a past and takes it over in some way or flees from it. Not only present in the present; it is engaged with the world in the present. This dynamism distinguishes Dasein from all present beings. If we analyze Dasein as an object with fixed properties, we have lost care. Dasein is always in motion of possibility, thrownness, and engagement. It is not a static entity; it is an open and temporal structure.
Here care opens the way toward “temporality”. Heidegger wants to show that the ultimate meaning of care lies in temporality. Dasein is ahead of itself, that is, futural; it is already in a thrown world, that is, past-oriented; it is engaged alongside beings, that is, present-oriented. Future, past, and present are not three separate parts of time, but three interconnected dimensions of the structure of care. Dasein's temporality is more fundamental than the clock and the calendar. We do not first experience time as a sequence of now-moments; we are temporal because we live with possibility, thrownness, and engagement. Care is the structure that shows that Dasein is temporal from the ground up. That is why, without understanding care, one cannot reach the understanding of temporality in “Being and Time”.
To clarify this point, one can look at everyday life. When someone is worried about the future of their work, they are not just in the present moment; a possible future casts its shadow over their present. When someone suffers from a past or is faithful to a heritage, the past is not just something over and done with; it acts in their present. When someone is engaged in a task, this engagement has meaning within the horizon of goals, expectations, habits, and possibilities. No present exists as an isolated point. Dasein is always linked from the future to the past and the present. Care is the name for this living connection. Thus, time for Dasein is not just something "in" which it lives; Dasein itself is temporal, because care is the structure of its Being.
From here one can see why Heidegger, with the concept of care, understands man not from the perspective of substance, but from the perspective of possibility and time. In the metaphysical tradition, beings were often understood on the basis of presence, stability, essence, and substance. But Dasein cannot be understood in this way. Dasein is always ahead of itself; it can never be reduced to a full presence in a now-moment. It is what it can still be, what comes from a past, and what is now engaged in. Care, with this structure, is a fundamental critique of the metaphysics of presence. Dasein is not a completely present being, but a temporal disclosedness. This point is important in Heidegger's whole project, because it moves the question of Being from the horizon of fixed presence to the horizon of temporality.
But is care only about the individual? The precise answer is that care begins with Dasein, but because Dasein is always with others and in history, care is never completely individual. Nevertheless, Heidegger in “Being and Time” focuses more on the existential structure of Dasein than on institutions, society, and objective history. This focus allows him to provide a very deep analysis of the human condition, but at the same time, some collective dimensions of care remain in the background. The care of a society, the historical care of a nation, the institutional care of a university, the political care of citizens, or the ecological care of humans toward the earth are topics that can be expanded from Heidegger, but are not fully developed in “Being and Time”. Thus, care is a concept with great capacity for expansion, but the book itself pursues it mainly at the level of the analysis of Dasein.
In the contemporary world, the concept of care can be very illuminating. One of the crises of modern life is that man appears to be busy with countless things, but may have lost his authentic care. He is concerned with work, income, social image, news, speed, competition, consumption, and security, but may ask less about what his Being is truly at issue in. His care is scattered among thousands of occupations. The digital world, the attention economy, the constant pressure for productivity, and the culture of success consume Dasein's care in superficial and scattered forms. From this perspective, returning to the concept of care means asking what is “really” at issue for us. Is our care our own or has it come from the "they"? Does what we are concerned about open our authentic possibility or distance us from ourselves? These questions show that care is not just a historical concept in a philosophical book; it is a tool for understanding our present.
At the same time, one must be careful that care does not become a simple psychological recommendation. Heidegger does not say that man should just pay attention to more important things or better manage his life. His problem is deeper. Care is the structure of Dasein's Being, not a recipe for personal peace. Dasein, even when it manages its life poorly, even when it flees from itself, even when it is lost in the "they," is still caring. The main question is not whether Dasein cares or not; the question is whether its care is authentic or inauthentic, scattered or taken over, coming from the "they" or accepted in its own resoluteness. This level of analysis separates care from motivational psychology or moral preaching. Heidegger is not seeking to reform behavior; he is seeking to reveal the structure of Being.
Care also shows that man is a vulnerable being. Because my Being is an issue for me, I can worry, fear, hope, lose, fail, and suffer. A being that does not care has no existential vulnerability. Because Dasein is engaged in the world and with others, it can be wounded; not only physically, but existentially. The loss of a possibility, the failure of a commitment, the collapse of a familiar world, the death of another, homelessness, exile, or the meaninglessness of language all shake Dasein, because it cares. This point can be a bridge between Heidegger and the ethics of care. If man is from the ground up a caring being, then human life always requires care, responsiveness, and attention to the vulnerability of others. Heidegger himself does not fully develop this conclusion, but the concept of care has the capacity for it.
In conclusion, one can say that care is the point where the scattered analyses of “Being and Time” reach unity. Dasein is in the world because its Being is an issue for it. Dasein is with others because the world of its care is a shared world. Dasein falls because it wants to flee from the burden of care. Dasein becomes anxious because care confronts it with the groundlessness of its Being. Dasein is toward death because its ultimate possibility illuminates all its care. Conscience calls it because it must reclaim its care from the "they." Resoluteness is the authentic response to this call. And temporality is the ultimate horizon of care, because Dasein from the future moves toward its possibilities, comes from a thrown past, and is engaged in the present with the world.
Thus, care must be considered the heart of the ontology of Dasein. This concept shows that man is neither a neutral subject, nor a present object, nor a merely biological animal, nor an individual separate from the world. Man is Dasein, and Dasein means care: the finite openness to one's own Being in a shared and temporal world. Care shows that human Being is always problematic, engaged, possible, and incomplete. From here, the path of “Being and Time” approaches its decisive point: if care is the fundamental structure of Dasein, what is the ultimate horizon of this structure? Heidegger's answer is “temporality”. Temporality is not one of Dasein's properties, but the ontological meaning of care. In the next section, we must show how future, past, and present, not as three external moments of time, but as three existential horizons of Dasein, return the entire analysis of “Being and Time” to the main question of the book: the relation between Being and time.
Temporality: The Horizon for the Meaning of Being and the Hidden Heart of Being and Time
If we were to reconstruct the path of “Being and Time” in its most fundamental form, we would have to say that Heidegger begins with the question of Being, arrives at the analysis of Dasein to pose this question, discovers the structure of Dasein in care, and then shows that the ontological meaning of care is “temporality”. Thus, temporality is not a subordinate part at the end of the book, not merely one of Dasein's properties, and not an additional discussion about the experience of time. Temporality is the hidden heart of the entire project of “Being and Time”. The title of the book also indicates this: the question of Being can only be understood through time. Heidegger does not mean to say that Being is the same as time, or that time is a being alongside other beings; he wants to show that the horizon for the understanding of Being for Dasein is temporality. Dasein is the being that understands Being, and this understanding is only possible because Dasein itself is at bottom temporal.
To understand this point, one must first distance oneself from the ordinary conception of time. We usually understand time as a sequence of successive moments: past, present, and future. The past is what is no longer; the future is what is not yet; the present is a point between them that is now and immediately passes. This understanding of time, which can be called linear, objective, or clock-time, is necessary in everyday life, science, historiography, planning, and calculation. We deal with clocks, calendars, dates, duration, priority, and succession. But Heidegger asks whether this understanding of time is the most fundamental understanding of time. Is time originally a sequence of now-moments? Or is this understanding itself based on a deeper experience of time? His answer is clear: clock-time and linear time are derivative forms of time, not its foundation. Fundamental time is the temporality of Dasein.
The temporality of Dasein does not mean that Dasein is "in time," as an object is in a container. Dasein is temporal because its Being is made up of future, past, and present as three existential horizons. It is not only present in the now-moment. Dasein is always ahead of itself, because it lives with its possibilities; it is already behind itself, because it is thrown and has a past, heritage, and facticity; and it is presently alongside beings and others, because it acts in the world, speaks, builds, fears, wants, and decides. Thus, future, past, and present for Heidegger are not three separate parts of time, but three "ecstases" or standing-out of temporality. Dasein is not closed in itself; it is always outside itself: toward the future, from the past, and among present beings.
The “future” has a primary place in this structure. This is one of Heidegger's main differences from the ordinary understanding of time. In everyday understanding, the present usually seems the most real part of time; the past is no longer and the future is not yet, but the present “is”. Heidegger reverses this priority. Dasein is at bottom “futural”, because it understands itself from its possibilities. Man is not only what he actually is now; he is always open toward what he can be. Even when remembering the past or doing something in the present, this remembering and acting have meaning within the horizon of future possibilities. A student studying, a worker working, a writer writing, a patient being treated, a person making a decision—all understand their present from a futural horizon. Dasein always comes toward itself from the future.
But this futurity, in its most authentic form, is clarified by death. The authentic future of Dasein is not merely a set of ordinary plans, hopes, goals, and possibilities. The authentic future is opened in the horizon of Being-toward-death. Death is Dasein's ultimate and non-transferable possibility; the possibility of the impossibility of all possibilities. When Dasein understands death as its own distinctive possibility, it understands its future not as an endless series of postponable choices, but as the finite possibility of its own Being. Thus, the authentic future is linked to the anticipation of death. This anticipation pulls Dasein out of dispersion in public possibilities and shows it that its Being cannot be indefinitely surrendered to the "they." Thus, the future for Heidegger is not merely "later," but the horizon of authentic possibility.
The “past” for Heidegger also does not mean something left behind that no longer exists. Dasein never leaves its past behind as a finished object. It always comes from a past; it is thrown into a language, a history, a body, a culture, a family, and a world. The past is present in Dasein as “thrownness”. I do not merely “remember” my past; I “come from” it. This past acts in my way of understanding, my possibilities, my fears, my language, my habits, my world, and my limitations. Dasein cannot erase its past, but it can take it over in some way or flee from it. In inauthenticity, the past often acts as habit, public tradition, and the interpretations of the "they." In authenticity, Dasein can take over its past as a heritage and make a future possibility from it.
This past-orientedness is precisely what Heidegger later develops in the discussion of Dasein's “historicity”. Dasein is not merely an individual with personal memories; it is “in” history. History for it is not a set of past events, but a horizon in which its possibilities are opened or closed. We always think in a historical language, live in historical traditions, and come from heritages that existed before us. Authentic understanding of the past does not mean blind repetition of tradition, but taking over heritage in the horizon of future possibility. Authentic Dasein does not understand the past as a dead object, but as a source of possibility. It can rediscover from the past possibilities that were concealed in everydayness. Thus, the past for Heidegger is “alive”, because it acts in care and future possibility.
The “present” also acquires a new meaning in this structure. The present is not just the now-point. The present, for Dasein, is the way of being engaged with the world. In the present, Dasein deals with equipment, others, tasks, situations, and beings. This presentness in everyday life often appears as occupation, dispersion, and absorption in tasks. Inauthentic Dasein lives in successive now-moments, becomes absorbed in tasks, moves from one thing to another, and transforms the present into a field of entertainment, haste, and consumption. But the authentic present, which Heidegger calls the “moment of vision” (“Augenblick”), is something different. The authentic moment does not mean a short and passing now; it is a moment in which Dasein, from its death-aware future and its taken-over past, “sees” the present situation and takes over its possibility in it.
This "moment" for Heidegger should not be confused with a fleeting feeling or a hasty decision. The authentic moment is a present that is not disconnected from the future and past. Resolute Dasein, in the horizon of death and with the taking-over of its thrownness, understands the present situation. It is not lost in everyday dispersion; it can see what possibility is now opened for it. This moment is not calendar time, but the existential concentration of temporality. In the authentic moment, future, past, and present meet: the future as death-aware possibility, the past as heritage and thrownness, and the present as the taken-over situation. Thus, authentic temporality shows itself in the moment as a living unity.
From here one can understand why care is fundamentally temporal. In the previous section, we saw that care means being-ahead-of-itself, being-in-the-world, and being-alongside-beings. Now it becomes clear that these three structures are the three dimensions of temporality. Being-ahead-of-itself is Dasein's futurity. Being-in-the-world and thrownness is its past-orientedness. Being-alongside-beings is its presentness. Thus, care does not merely occur “in” time; care itself is temporal. Dasein is temporal because it cares; and because it is temporal, it can understand Being. This point is the central link of the argument of “Being and Time”. Heidegger wants to show that the horizon for the understanding of Being is time, because the being that understands Being, namely Dasein, is at bottom temporal.
This view differs fundamentally from the traditional metaphysical understanding of Being. Western metaphysics, in Heidegger's reading, has often understood Being on the basis of “presence”. What is, is what is present, stable, enduring, available, and knowable. From Plato to Descartes, and from Aristotle to Hegel, despite many differences, a kind of priority of presence remained in the understanding of Being. But Heidegger says that Dasein cannot be understood on the basis of presence. Dasein is never merely present; it is always futural, past-oriented, and present. If Dasein is the horizon for the understanding of Being, then Being itself should not be understood only from the perspective of presence. The temporality of Dasein is a fundamental critique of the metaphysics of presence. For this reason, “Being and Time” is not merely an analysis of man; it is an attempt to transform the horizon for the understanding of Being.
The difference between authentic and inauthentic time becomes important here. In inauthentic temporality, Dasein understands itself from the everyday world and the "they." The future for it appears mostly as expectation, plan, success, worry, or public possibilities. The past acts as habit, unquestioned tradition, forgetfulness, or scattered memories. The present is lived as occupation, entertainment, haste, and dispersion. Inauthentic Dasein lives in time, but has not made time authentically its own. It is driven from one now to another, lives in public expectations and ordinary fears, and takes its past and future from the "they." Such time is the time that in everydayness becomes clock, schedule, opportunity, delay, hurry, and the consumption of moments.
In authentic temporality, Dasein returns from its death-aware future toward its own possibility, takes over its thrown past, and in the moment sees its situation. This does not mean leaving everyday time. Authentic Dasein still lives with clocks and calendars, works, makes appointments, and is present in the public world. But its relation to time is transformed. Time is no longer merely something to be filled, consumed, managed, or not lost; time is the horizon of the possibility of its Being. In authenticity, Dasein understands that having time or not having time is not just a matter of scheduling; it is a matter of Being. It understands that its temporal life is finite and it must take over its possibility within this finitude.
This analysis is also very important for understanding the crisis of time in the modern world. Modern man more than ever measures time, manages it, divides it, stores it, sells it, and buys it. Work time, production time, consumption time, media time, education time, transport time, leisure time, and sleep time are all placed within systems of calculation and productivity. But precisely in this domination of measurement, authentic experience of time may be lost. Man may always be in a hurry, but not know toward what possibility he is moving. He may have a full calendar, but have lost his own temporality. He may fill the future with many plans, but forget his authentic future. Heidegger helps us understand that the crisis of time is not just a lack of time; it is the forgetting of the existential temporality of Dasein.
In relation to the past, the modern world is also ambiguous. On one hand, history becomes a subject of research, data, archive, and narrative; on the other hand, Dasein may lose its authentic relation to heritage. The past either becomes nostalgia or something dead and merely past. Heidegger proposes another path: the past must be understood as thrownness and heritage. Dasein can neither erase the past nor blindly repeat it. Taking over the past means understanding where I have come from, what possibilities are hidden in this heritage, and how an authentic future can be opened from it. This understanding of history differs from superficial historicism or simple traditionalism. The past is neither a prison nor a museum; it is a horizon of possibility, if authentically taken over.
Here one must also note the dangers of this discussion. The concepts of heritage, destiny, and historicity in Heidegger, if understood uncritically, can approach the dangerous language of collectivism, ethnicism, or historical fate. Heidegger himself later showed, in some political and historical positions, that this language can be slippery. Therefore, any responsible reading of temporality and historicity must distinguish between taking over heritage and submitting to the myth of collective destiny. The past must be a source of critical possibility, not a tool for excluding the other or closing the future. Authentic historicity does not mean blind loyalty to heritage; it means opening the hidden possibilities of the past in dialogue with the future. This point is essential to prevent political misuse of Heidegger.
Temporality is also related to truth. If truth for Heidegger is unconcealment, this unconcealment is always temporal. Something can only be disclosed within a horizon of expectation, remembrance, possibility, repetition, decision, and presence. Our understanding of everything is temporal. A work of art, a tradition, a relation, a thought, or even a tool acquires meaning over time. In our encounter with the world, we are never in an empty, pastless present; we always come with pre-understandings and are open to possibilities. Thus, truth is not a timeless event, but a temporal disclosedness. This point is later developed in Heidegger's later thinking as the history of Being: truth itself is disclosed and concealed in different ways in different histories. The root of this thought is in the temporality of “Being and Time”.
On the other hand, the temporality of Dasein shows that self-knowledge is also not timeless. Man cannot know himself as a present and complete object. I am always in the process of becoming, returning, re-understanding, forgetting, deciding, and possibility. My self is neither a fixed core behind all experiences, nor a scattered collection of moments. The self of Dasein is formed in the temporality of care. I understand myself from the future of my possibilities, the thrownness of my past, and the engagement of my present. Thus, selfhood means being temporal. This point shows Heidegger's difference from many theories of identity. Human identity is not only in the memory of the past, not only in the free choice of the future, and not only in the presence of the present; it is in the temporal unity of care.
This temporal unity is more fully understood with death. Death is Dasein's ultimate future, but this future is not only at the end. Death temporalizes the whole of life from within. Because death exists, the future is limited; because the future is limited, the past must be taken over in some way; because the past and future are such, the present can become the moment of resoluteness. Thus, death concentrates authentic temporality. If Dasein conceals death, it also understands its time inauthentically: the future becomes postponement, the past habit, the present entertainment. But if it understands death as its own distinctive possibility, its temporality can become authentic: the future becomes possibility, the past heritage, the present the resolute situation.
Now one can understand more clearly why “Being and Time” remained incomplete. Heidegger was able to show that Dasein is temporal and that temporality is the horizon for Dasein's understanding of Being. But the next step was more difficult: how to move from the temporality of Dasein to the meaning of Being itself? How to show that Being, not just for Dasein, but in itself, is understood in the horizon of time? The parts of the book that were to complete this transition were never published. Later, Heidegger himself changed the direction of his questioning and, instead of continuing directly with the analysis of Dasein, turned to the history of Being, the event, language, and technology. This change of direction shows that the temporality of Dasein, though necessary, was not sufficient for the ultimate question of Being. Nevertheless, without this analysis, the later Heidegger is also incomprehensible.
The incompleteness of the project should not be seen simply as failure. Sometimes in philosophy, incompleteness is not a sign of failure, but a sign that the question has become larger than its original framework. “Being and Time” began with the analysis of Dasein, but this analysis itself brought Heidegger to a point where he could no longer remain within the framework of Dasein alone. If the temporality of Dasein is the horizon for the understanding of Being, one must ask about the history of the disclosedness of Being itself. From here, the path to the later thinking is opened. But in “Being and Time” itself, temporality remains the peak of the analysis. All the previous concepts, from Being-in-the-world to death and resoluteness, acquire meaning in temporality. Temporality is the thread that secretly binds the book from beginning to end.
From a critical perspective, one can say that Heidegger's analysis of time is very profound, but its focus on individual Dasein leaves some dimensions of collective and historical time in the background. Social time, work time, the time of capital, the time of colonialism, the time of political waiting, the time of inequality, the time of the body, and the time of care all require analyses that are not developed in detail in “Being and Time”. For example, not all humans have the same access to the future. Poverty, discrimination, illness, war, migration, or oppression can limit or block the future. The past is not always a heritage that can be taken over; sometimes it is a historical wound, a burden of violence, or a suppressed memory. The present is not for everyone a field of free resoluteness; sometimes it is a field of coercion, survival, and pressure. Thus, Heidegger's temporality must be supplemented by social and political analysis of time.
Despite this criticism, Heidegger's achievement is fundamental. He shows that man cannot be understood without time, and time cannot be understood only with clocks and calendars. Temporality means that Dasein is opened from the future toward its possibilities, comes from a thrown past, and is engaged in the present with the world. These three horizons are not separate; they constitute the structure of Dasein's Being in the unity of care. Thus, man is not “in” time, but is temporal “in a certain way”. He is not a fixed presence in the present; he is a tension between possibility, heritage, and situation. This understanding moves philosophy from the search for fixed essences toward the understanding of dynamism, finitude, and openness.
In conclusion, one can say that temporality is the heart of “Being and Time”, because it shows why the question of Being must pass through Dasein and care. Dasein is the being that understands Being, because it is disclosed in the world; it is disclosed in the world because it cares; and care is at bottom temporal. Future, past, and present are not three external moments, but three existential dimensions of Dasein. The future is revealed in possibility and death, the past in thrownness and heritage, and the present in situation and engagement with the world. Inauthentic temporality scatters Dasein in public expectations, habits, and occupations; authentic temporality returns it from death-aware future, to taken-over past, and resolute present. From here, “Being and Time” acquires meaning as a foundational work: a book that showed that man cannot be understood except from the horizon of time, and that Being cannot be questioned except by passing through the temporality of Dasein.
Historicity, Heritage, and Destiny: Dasein within the Horizon of History
After the analysis of temporality, Heidegger takes another step and shows that Dasein is not merely a temporal being, but also a “historical” one. “Historicity” (“Geschichtlichkeit”) is one of the most difficult and sensitive concepts of “Being and Time”, because on one hand it is a natural continuation of the analysis of temporality, and on the other hand, it opens the way to questions that later become very important in Heidegger's thinking, especially in the discussions of the history of Being, heritage, destiny, people, tradition, and historical beginnings. If Dasein is from the ground up temporal, that is, if its Being is shaped in the horizon of future, past, and present, then it cannot be understood as a being without history. Dasein never begins from point zero. It is born into a language spoken before it, lives in a world built before it, thinks in traditions formed before it, and is confronted with possibilities that history has opened or closed for it. Thus, history for Dasein is not something external; it is part of the structure of its Being.
In the everyday view, history usually means the past; a set of events that once occurred and can now be recorded, narrated, studied, or remembered. In this view, history is something "behind" us. We live in the present, and history is a past that we either know or do not know. But Heidegger considers this understanding superficial and derivative. History, before being a set of past events, is a way of Dasein's Being. Dasein is historical because its past is not merely something left behind; the past acts in its present and future possibilities. Language, tradition, institutions, memories, failures, victories, education, wounds, narratives, and patterns of understanding are all present in Dasein's present. The past has passed, but it is not finished. The past continues in Dasein as heritage, habit, possibility, burden, wound, or call.
From here the difference between history as a science and historicity as an existential structure becomes clear. Historiography can examine events, analyze documents, compare narratives, and make the past an object of knowledge. This work is important and necessary, but for Heidegger, it is itself possible on the basis of Dasein's historicity. Only a being that is itself historical can write history. Dasein is interested in the past because it itself comes from a past and its Being is shaped in relation to the past. If the past had no relation to Dasein's present and future possibilities, historiography would have no existential meaning. Thus, scientific history is based on existential historicity. We do not merely “read” history; we “live” in history. History is not just an object of knowledge; it is the horizon of our Being.
Dasein's historicity is based on its temporality. In the previous section, we saw that Dasein is opened from the future toward its possibilities, comes from a thrown past, and is engaged in the present with the world. This past-orientedness at a deeper level becomes historicity. Dasein has a personal past, but this past is never merely personal. I am born into a world whose language, institutions, religion, science, politics, family, technology, art, collective memory, and historical narratives existed before me. Even my most individual experiences occur within the horizon of meanings that are historical. Fear, love, death, work, success, failure, faith, freedom, justice, and identity have all acquired meaning in specific histories. Thus, Dasein, though in each case mine, is always historical. My Being is from the start shaped in a linguistic, cultural, social, and historical heritage.
But Heidegger does not understand historicity merely as dependence on the past. If Dasein were merely a product of the past, historicity would become historical determinism. Whereas Dasein is a possible being and can have a different relation to its past. It can forget the past, flee from it, blindly repeat it, turn it into nostalgia, or authentically take it over. Authentic historicity occurs when Dasein understands its heritage not as a closed chain, but as a source of possibility. “Heritage” (“Erbe”) for Heidegger does not mean a collection of cultural possessions to be preserved unquestioningly. Heritage is a possibility that has come to Dasein from the past and can be reopened in the horizon of the future. Authentic historicity means choosing and taking over heritage in the light of future possibility, not unthinking imitation of the past.
Here the concept of “repetition” (“Wiederholung”) becomes important. Repetition for Heidegger does not mean mechanical reproduction of the past. Authentic repetition means a creative return to a possibility that was opened in the past, but concealed in everydayness, superficial tradition, or historical forgetfulness. Authentic Dasein can rediscover from the heritage of the past a possibility and take it over in the present situation in a new way. For example, a return to a thinker, a tradition, a historical experience, or a political and cultural possibility, if it is merely nostalgic return, is inauthentic. But if it transforms that past into a living question for the future, it can be authentic repetition. Thus, Heideggerian repetition is neither simple conservatism nor rootless innovation; it is a retrieval of possibility. The past should neither be worshipped nor set aside; it should be reopened in a questioning way.
This view of history transforms Dasein's relation to tradition. In everyday life, tradition often acts as something ready-made, established, and unquestioned. The "they" say it has always been this way, it must be this way, the ancestors did this, the right path is this. In this state, tradition becomes part of falling; Dasein uses tradition to escape the responsibility of questioning and choosing. But tradition can also have a more authentic meaning. Tradition can preserve possibilities that are not yet exhausted. Authentic Dasein does not understand tradition as a ready-made answer, but as a field of questioning. It asks what possibility is hidden in this heritage that can open the future. Such a relation to tradition differs from both blind traditionalism and superficial rupture from the past. Authentic historicity means the ability to live in a living dialogue with the past.
From here one can understand that the future and the past in historicity are not separate. Dasein can only authentically take over the past if an authentic future is opened before it. The death-aware and resolute future brings the past out of the state of habit and dead burden and transforms it into a heritage that can be chosen. On the other hand, the future is not constructed from nothing; the authentic future is always opened from the heart of the past and heritage. If Dasein forgets its past, its future becomes superficial and rootless. If it is frozen in the past, its future is closed. Authentic historicity occurs in the tension between these two: returning to the past to open the future. This is the existential meaning of repetition. Repetition means freeing the future from the hidden possibilities of the past.
Heidegger in this context also speaks of “destiny” (“Schicksal”) and the “destiny of a community” (“Geschick”). These concepts are among the most sensitive parts of “Being and Time”, because later, in relation to politics and history, they become open to misunderstanding and misuse. At the level of “Being and Time”, destiny does not mean that an external and compulsive force has predetermined Dasein's life. Destiny means that resolute Dasein, in the horizon of death and historicity, takes over its own distinctive possibility and emerges from dispersion in the "they." It is placed in a historical heritage and from it chooses a possibility. This choice is not arbitrary and rootless; it arises from Dasein's past, situation, and finite future. Thus, destiny for Heidegger means more the historical taking-over of possibility than submission to a predetermined fate.
But Dasein is never alone. It is with others, and its historicity also occurs in a shared world. Thus, Heidegger speaks of the “destiny of a community”; that is, the historical possibility that is formed in the Being-with of Daseins. A generation, a society, a tradition, or a historical community can be confronted with shared possibilities. Here historicity moves beyond the individual level and approaches the collective horizon. But precisely at this point, one must be very cautious. Speaking of shared destiny, if not accompanied by critique, plurality, freedom, and responsibility, can become the dangerous language of ethnicism, historical fate, and the exclusion of differences. History has shown that words like destiny, nation, heritage, and beginning, if used uncritically and poetically, can become tools of power. Therefore, a contemporary reading of this part of “Being and Time” must see both its philosophical capacity and its dangers.
The philosophical capacity of this discussion lies in not understanding man as a rootless and ahistorical being. Dasein always comes from a heritage and finds its possibilities in a shared world. No human freedom begins from nothing. We always choose within a historical context. But the danger of the discussion is that historicity can be reduced to a closed identity, a rigid collective fate, or an exclusive narrative of heritage. In such a case, authentic historicity gives way to historical myth. Heritage is no longer a field of questioning, but becomes a command. The past is no longer a possibility for the future, but becomes a tool for closing the future. Therefore, one must distinguish between heritage as “possibility” and heritage as “ideology”. Heidegger does not clearly provide the tools for this political distinction, but a critical reading today is obliged to make it.
In relation to historiography, Heidegger also has an important point. He wants to show that authentic historiography is not merely collecting data about the past. The historian is also a historical Dasein who looks at the past from the questions of the present and the possibilities of the future. No historiography is performed completely outside history. This does not mean simple relativism; it does not mean that every narrative of the past is equally true. Rather, it means that historical understanding always occurs within a horizon of question, pre-understanding, and possibility. The historian does not see the past from a timeless point; he himself stands in history. Thus, historical knowledge also has a hermeneutical structure. This idea was later developed in Gadamer's hermeneutics: we always stand in the history of the effect of traditions, and our understanding of the past is a dialogue between the horizon of today and the horizon of the past.
Historicity also shows that Dasein can get lost in the past, just as it can get lost in the everyday present. Getting lost in the past has two opposing but related forms. One form is blind traditionalism; Dasein turns the past into a ready-made answer and flees from the possibility of questioning. The other form is a superficial rupture with the past; Dasein thinks it can be completely new, rootless, and independent of heritage. In both cases, the past is not properly taken over. Traditionalism freezes the past; superficial rupture ignores the past. Authentic historicity is a more difficult path: neither dead repetition of the past nor its forgetfulness, but the retrieval of the past's possibilities in the horizon of the future. This difficult path requires questioning, critique, and resoluteness.
For example, a society that only takes pride in its past, without questioning it, remains in inauthentic historicity. If it only negates its past and thinks it can begin from nothing, it is still inauthentic. An authentic relation to history is one in which society can see both its greatness and its failures, both its living possibilities and its hidden wounds. Such a view of history is neither propagandistic nor contemptuous; neither nostalgic nor rootless. Heidegger raises this discussion at a more abstract level in “Being and Time”, but its implication for understanding societies and cultures is very important. Authentic historicity requires the courage to confront the past; a past that is not only a source of pride, but sometimes a source of responsibility and questioning.
At the individual level, this is also true. Man cannot erase his past. Childhood, family, failures, choices, errors, memories, lessons, and wounds are all present in his present. But he is not condemned to merely repeat the past. Dasein can “take over” the past; that is, understand it, see its hidden possibilities, accept its responsibility, and build a future from it. This taking-over differs from forgetting. Forgetting may appear to bring peace, but the forgotten past often returns in other forms. Taking over the past means that Dasein, instead of fleeing from it, places it in the projection of its future. This is existential historicity: the past is not a closed prison, but part of the possibility of the future.
Dasein's historicity is also linked to the concept of “generation”. Daseins live in different historical times, and each generation confronts specific possibilities and limitations. A generation is not just a group of the same age; it is a historical horizon of experience, possibility, crisis, and heritage. Each generation receives things from the past and passes something on to the future. From this perspective, Dasein is related not only to its own death, but also to historical transmission. It lives in a world that came from ancestors and will pass to descendants. This point, though not fully developed into an intergenerational ethics in “Being and Time”, has the capacity for such an interpretation. Historicity means that we do not live only for ourselves; we are placed in a chain of transmission, responsibility, and possibility.
In today's world, this intergenerational dimension has special importance. The environmental crisis, technology, war, historical memory, education, language, and culture all show that today's decisions are not only about the present. They shape the future of generations not yet born. If we understand historicity only as relating to the past, we miss this dimension. Dasein is historical because it comes from the past and passes on to the future. Heritage is not only what we have received; it is what we leave behind. Thus, one can link Heideggerian historicity with responsibility toward the future, though Heidegger himself does not fully develop this link in ethical and political language. Resolute Dasein must see not only the heritage of the past, but also the future consequences of its Being.
Now one can understand the link between historicity and authenticity more clearly. Inauthentic Dasein is scattered in everyday time; its future is public expectations, its past is unquestioned tradition or forgetfulness, and its present is the occupations of the "they." Authentic Dasein, in anticipatory resoluteness, accepts its death-aware future, takes over its past as heritage, and in the moment sees its situation. Authentic historicity is precisely this temporal taking-over. Authentic Dasein does not say the past has no importance; nor does it say the past determines everything. It understands the past from the future and opens the future from the heart of the past. This dialectic, without Hegelian system-building, is one of the subtlest parts of “Being and Time”.
Nevertheless, one must note the difference between Heidegger and Hegel. For Hegel, history is a rational process in which spirit achieves self-consciousness. History ultimately has a universal and systematic meaning. But Heidegger in “Being and Time” does not present such a universal and rational history. He begins historicity from Dasein and its temporality, not from the movement of absolute spirit. History for him is more a horizon of possibility, heritage, and taking-over than a necessary process toward a final end. Of course, in the later thinking, the history of Being acquires a more comprehensive place, but in “Being and Time”, the focus of the analysis remains Dasein. This difference is important, because it separates Heideggerian historicity from classical philosophy of history. He does not want to discover the law of history; he wants to show how Dasein is historical.
This point also clarifies Heidegger's difference from simple historicism. Historicism may say that everything is historical and every thought or value must be understood only in its historical context. Heidegger asks more deeply: on what structure is this historicity itself based? His answer is the temporality of Dasein. Because Dasein is futural, past-oriented, and present, it can be historical. Thus, historicity is neither historical relativism nor the lawfulness of a philosophy of history; it is the existential structure of Dasein. This structure allows us both to learn from history and to critique it; both to take heritage seriously and to move beyond it; both to understand the past and to open the future.
In relation to truth, historicity is also important. If Dasein's understanding is historical, then truth in human experience is always disclosed in a historical horizon. This does not mean that truth is arbitrary or merely relative. Rather, it means that every disclosedness of truth occurs in a historical world. Concepts, questions, languages, and possibilities of understanding are historical. Philosophy is also not outside history. The question of Being, which Heidegger wants to revive, has itself been concealed in the history of Western philosophy and must be reopened through the phenomenological destruction of that history. Thus, Dasein's historicity provides the ground for the method of the destruction of the history of ontology. To question Being, one must reread the history that has concealed this question. This is where “Being and Time” connects to the larger project of the critique of the history of metaphysics.
From the final perspective of this article, historicity is a bridge between “Being and Time” and the later Heidegger. In “Being and Time”, historicity is primarily the structure of Dasein. But in the later works, Heidegger speaks of the history of Being; that is, of how Being itself has been disclosed and concealed in different ways in different historical epochs. Although there is a difference between these two stages, their connection is clear. Dasein's historicity showed that the understanding of Being is not without history. The later thinking expands this point and asks how the history of the disclosedness of Being itself has occurred. Therefore, understanding historicity in “Being and Time” is essential for understanding Heidegger's entire intellectual path. This concept shows that the question of Being is from the start linked to time, heritage, and history.
In conclusion, one can say that Dasein's historicity is one of the most important results of the analysis of temporality. Dasein is historical because it is temporal; because it comes from a thrown past, it confronts heritage; because it is open to the future, it can take over this heritage authentically or inauthentically; because it is with others, its historicity always occurs in a shared world. History for Dasein is not merely something behind, but a horizon of possibility ahead. An authentic relation to history is neither dead repetition of the past nor rootless rupture from it; it is the retrieval of the possibilities of the past in the horizon of the future. But this concept must be accompanied by political and ethical critique so that it does not become the dangerous language of closed fate, ethnicism, or historical myth. A responsible reading of Heidegger must understand historicity as the critical taking-over of heritage, not submission to fate.
Thus, historicity shows that Dasein is not merely an individual and finite being, but a being of heritage and transmission. It lives in a world that has come from ancestors and will pass to descendants. It can hide in dead traditions or open the living possibilities of the past for the future. It can turn history into a museum, ideology, or unquestioned pride, or transform it into a field of questioning, responsibility, and possibility. “Being and Time” with this analysis moves our understanding of history from the level of past events to the level of human Being. Man is historical because his Being never begins from nothing and never remains closed in the present. He always comes from a past, decides in a present, and is open to a future. Historicity is the name for this finite and heritage-laden openness.
Truth, Unconcealment, and Disclosedness: A Critique of Truth as Correspondence
One of the less understood but very decisive parts of “Being and Time” is Heidegger's analysis of truth. At first glance, it might seem that the main concerns of the book are Dasein, temporality, death, conscience, and care, and that the discussion of truth is of secondary importance. But this impression is not accurate. The question of truth in “Being and Time” is at the heart of Heidegger's project, because if the main question of the book is the question of the meaning of Being, it must be clarified how beings are at all disclosed for Dasein. Truth, for Heidegger, prior to being a property of propositions, is the event of disclosedness. A proposition can be true or false, but prior to that, a world must be disclosed in which something can appear as something and then be judged about it. Thus, the analysis of truth in “Being and Time” is a direct continuation of the analysis of Being-in-the-world, worldhood, and Dasein's disclosedness.
In the common philosophical tradition, truth has usually been understood as “correspondence”: the correspondence of a proposition with reality, of thought with object, of judgment with fact. When we say "the book is on the table," this proposition is true when the book really is on the table. Such an understanding of truth seems obvious and largely necessary. In everyday life, science, law, historiography, and ordinary dialogue, we inevitably speak of the truth and falsity of propositions. Heidegger does not simply deny this meaning. He does not say that correspondence has no importance or that propositions cannot be true or false. His critique is more fundamental. He asks on what does the very possibility of correspondence rest? Prior to a proposition corresponding to reality, something must have been disclosed in the world. Prior to my saying "the book is on the table," the book, the table, being-on, place, language, and a world in which this relation has meaning must have been disclosed for me. Thus, propositional truth is based on a more fundamental truth: disclosedness or unconcealment.
To express this fundamental meaning of truth, Heidegger returns to the Greek word “aletheia”. Aletheia he understands not merely as correctness or correspondence, but as “unconcealment” (“Unverborgenheit”). Truth means something emerges from concealment and shows itself. This meaning, for Heidegger, is more fundamental than the ordinary meaning of truth as propositional correctness. Because a proposition can only be true about something that has previously been disclosed in some way. If no world were disclosed, if no being appeared in the horizon of Dasein's understanding, if nothing were understood “as” something, then no proposition could be corresponding or non-corresponding. Thus, correspondence always rests on unconcealment. With this analysis, Heidegger does not want to destroy logic and science; he wants to show that logic and science rest on a pre-logical and pre-scientific horizon of disclosedness.
This point can be better understood through the analysis of equipment. When we say "the hammer is heavy" or "the hammer is on the table," we have made a proposition about the hammer. But prior to this propositional level, the hammer has been disclosed for us in the world of work and equipment. The hammer is not merely a present object; it is something for hammering, building, repairing, and accomplishing a task within a network of references. This pre-propositional disclosedness is the condition for the possibility of any judgment about the hammer. If the hammer had no meaning in any world, if no practical relation and understanding were established with it, our propositions about it would also be groundless. Thus, truth does not first occur at the propositional level; it occurs at the level of the disclosedness of the world. Dasein is in the world, and the world is already disclosed for it to some extent; it is only on the basis of this disclosedness that propositions can be true or false.
To explain this structure, Heidegger uses the concept of “disclosedness” (“Erschlossenheit”). Dasein is a disclosed being; that is, itself, the world, and beings are manifest in the horizon of its Being. This disclosedness is composed of three main structures: “attunement” (“Befindlichkeit”), “understanding” (“Verstehen”), and “discourse” (“Rede”). Attunement shows that Dasein always finds itself in a mood and that the world through this mood acquires color, weight, and meaning for it. Understanding shows that Dasein is always open to possibilities and understands beings in relation to its possibilities. Discourse shows that this attuned understanding can be articulated and brought to language. Thus, fundamental truth is rooted in Dasein's disclosedness. Because Dasein is disclosed, beings can become manifest. And because beings become manifest, propositions about them can be true or false.
From here the important difference between truth and correctness becomes clear. Correctness (“Richtigkeit”) relates to the correspondence of a judgment with its subject. But truth in the fundamental sense is unconcealment and disclosedness. Correctness is not possible without truth, but truth in the fundamental sense is not reducible to the correctness of a proposition. For example, a proposition may be formally correct, but placed in a very limited, superficial, or even concealing horizon. One may have precise data about a human being, but not see their existential truth. One may have correct measurements about nature, but understand nature only as a source and reserve, and be blind to other ways of its disclosedness. One may have precise statistics about society, but not disclose the suffering, meaning, experience, and possibilities of the people in it. Therefore, correctness can operate within a horizon of deeper concealment. This point is very important for the critique of the modern world: our age may be very rich in information and partial correctness, but may be poor in truth in the sense of disclosedness.
Of course, Heidegger does not say that truth is merely relative or subjective. If truth is unconcealment, one should not think that everyone can call anything truth arbitrarily. Unconcealment always occurs in a structured world. Beings show themselves, but not arbitrarily and not outside any horizon. World, language, history, equipment, body, others, and Dasein's possibilities all play a role in the way things are disclosed. Truth is neither merely in the human mind nor merely in things as ready-made. Truth is the event of disclosedness between Dasein and the world. Dasein does not create truth in an arbitrary sense, but is disclosed in truth and allows beings to appear as what they are. This "allowing to appear" differs from subjective domination. Truth for Heidegger is more a kind of disclosedness and letting-be of appearance than a conceptual appropriation of things.
Here the relation between truth and freedom also appears. If truth is unconcealment, freedom is not merely the ability to choose among options, but openness to the appearing of beings. Dasein is free because it can stand in a horizon of disclosedness and allow things to show themselves. This freedom is prior to political or ethical freedom in the ordinary sense, though it can relate to them. Inauthentic Dasein, in the "they," idle talk, curiosity, and ambiguity, loses its freedom, because it no longer allows things to show themselves from themselves and in their own way; it sees things through ready-made interpretations. Authentic Dasein, with anxiety, death, conscience, and resoluteness, can take over its disclosedness anew. Thus, truth and authenticity are related. Authenticity is not just a matter of the individual self; it is also a matter of one's relation to truth.
This analysis of truth is also a serious critique of everyday idle talk. In idle talk, language appears to transmit truth, but in reality it can conceal it. Public talk, by repeating ready-made meanings, shows the world in a familiar and unquestioning way. In such a space, propositions may be true, but Dasein's relation to truth is inauthentic. One can repeat many true statements, but have no authentic encounter with the subject. This is where the difference between knowing and understanding, hearing and seeing, information and truth becomes apparent. Truth in the Heideggerian sense requires disclosedness, not just the circulation of correct propositions. This point has fundamental importance in today's world, which is flooded with information. The problem is not just a lack of information; sometimes the problem is an abundance of information that prevents deeper disclosedness.
On the other hand, truth is always accompanied by “concealment”. This is one of the subtlest points of Heidegger's thought. Unconcealment never means complete and final disclosedness of everything. Every disclosedness simultaneously conceals something. When something is disclosed from a particular angle, other angles remain in shadow. When nature is disclosed as a subject of physics, its poetic, religious, lived, ecological, or dwelling aspects may be concealed. When man is disclosed as statistical data, his face, suffering, hope, and uniqueness may remain concealed. When a work of art is disclosed as a commodity or museum object, the event of truth in it may be concealed. Thus, truth is always related to untruth. Untruth is not just error or falsehood; it is the concealment that is present in every disclosedness.
Heidegger in “Being and Time” speaks of “untruth” (“Unwahrheit”) and does not understand it merely as propositional falsity. Untruth belongs to concealment. Because Dasein is disclosed, it can conceal. Because it understands, it can misunderstand. Because it has language, it can fall into idle talk. Because the world is disclosed for it, it can get lost in the superficial disclosedness of the world. Thus, truth and untruth are not completely separate realms. Dasein always lives in a mixture of disclosedness and concealment. This point is linked to the analysis of falling. Falling means that Dasein lives in a world that appears disclosed and familiar, but this familiarity itself is concealing. The "they" have explained everything, but these very explanations prevent questioning. Untruth here is not absolute darkness, but the superficial and deceptive brightness of everydayness.
From this perspective, philosophy for Heidegger is an attempt to reopen what has been concealed in obviousness. Philosophy does not “produce” truth; it “opens” the way for unconcealment. This is not easy, because concealment does not always appear as obvious ignorance. Sometimes what is most concealing is precisely what seems most obvious and clear. Being is forgotten for this reason: not because no one speaks of it, but because everyone assumes its meaning is clear. Fundamental truth must be questioned from the heart of this obviousness. “Being and Time” in its entirety does precisely this: it breaks the obviousness of man, world, time, death, language, truth, and Being, and shows that what is closest is often most concealed.
The analysis of truth also clarifies the relation of “Being and Time” to phenomenology. Phenomenology means letting phenomena show themselves. But if truth is unconcealment, phenomenology is also the method of unconcealment. Phenomenology does not want to impose an external theory on things; it wants to free what shows itself from the coverings of tradition, language, theory, and everydayness. This does not mean that phenomenology is absolutely presuppositionless. Heidegger himself has shown that every understanding is placed in the hermeneutical circle. But phenomenology can clarify its pre-understandings and try to give the phenomenon space to appear. Thus, truth as unconcealment is linked to the method of the whole book. “Being and Time” itself is an exercise in opening phenomena that everyday life has concealed.
Here one must pay special attention to the relation between truth and Dasein. Heidegger says that Dasein is "in truth." This does not mean that Dasein always has correct propositions or always knows truth. Dasein is in truth because it is disclosed; because the world, itself, and beings are manifest for it. But Heidegger also says that Dasein is "in untruth," because this disclosedness is always accompanied by falling, concealment, ambiguity, and forgetfulness. Dasein is a being for whom truth is possible, but this very possibility of truth also includes the possibility of untruth. A stone is neither in truth nor in untruth, because the world is not disclosed for it. But Dasein, because it has a world, can disclose or conceal truth. Thus, truth and untruth belong to Dasein's structure.
This view also deepens the meaning of error. Error is not just a false proposition. Error can be a way of Being in the world. Dasein may be in untruth in its whole way of living, even if many of its propositions are true. If one understands oneself entirely from the "they," if one sees the world only as a field of consumption and competition, if one sees the other only as a role or tool, if one always postpones death, if one treats the past only as a burden or unquestioned pride, one lives at a deep level in untruth. In contrast, existential truth does not always mean having correct answers; sometimes it means openness to questioning, acceptance of finitude, hearing conscience, and seeing one's own situation. With this analysis, Heidegger moves truth from the level of the proposition to the level of Dasein's life.
Nevertheless, one must be careful that this understanding of truth does not lead to indifference toward propositional correctness. Some superficial readings of Heidegger might suppose that because fundamental truth is unconcealment, propositional correctness has no importance. This conclusion is dangerous and incorrect. Heidegger does not want to negate propositional correctness; he wants to show its foundation. In scientific, historical, ethical, and political life, the distinction between true and false is essential. One cannot, in the name of unconcealment, be indifferent to objective facts, historical documents, real suffering, or ethical responsibilities. A responsible reading of Heidegger must preserve both levels: truth as fundamental unconcealment, and correctness as the responsiveness of propositions to reality. If the second level is eliminated, thought falls into ambiguity and even misuse. If the first level is eliminated, truth is reduced to information and superficial correspondences.
This point has special importance in politics and history. A propaganda system may present some correct propositions within a larger narrative that conceals truth. Precise statistics may be presented, but the main question may remain hidden. A seemingly scientific language may be used, but human beings may be reduced to data and case studies. Thus, Heidegger's critique of truth as correspondence can make us sensitive to the limitations of official, administrative, technical, and media truth. But this same critique should not become relativism or irresponsibility toward reality. Truth is unconcealment, but unconcealment must be able to be accompanied by precision, documentation, judgment, and accountability. This supplementation, especially after the political experiences of the twentieth century, is essential.
The relation of truth to temporality is also very important. If Dasein is temporal and truth occurs in Dasein's disclosedness, then truth in human experience is not separate from time. The disclosedness of everything occurs within a horizon of past, future, and present. We see something from a historical pre-understanding, give it meaning in the horizon of future possibility, and encounter it in the present situation. Truth as unconcealment is not a timeless event outside history. Of course, this does not mean that every truth is merely relative to time; rather, it means that the disclosedness of truth for Dasein is always temporal and historical. This same point opens the way to the later Heidegger's thinking about the history of truth and the history of Being. In “Being and Time”, truth is analyzed in Dasein's disclosedness; in the later works, Heidegger speaks more of the history of the disclosedness of Being itself.
The analysis of truth in “Being and Time” is also a preparation for the critique of technology in the later works. If truth is the way beings are disclosed, then technology is not just a set of tools, but a way of disclosedness. In the technological world, beings are disclosed as reserve, resource, data, and exploitable capability. This disclosedness may be very precise, efficient, and propositionally correct, but at the same time it may conceal other ways of truth. Nature is disclosed in scientific and industrial calculation, but perhaps as earth, home, the beautiful, or a being worthy of care, it remains concealed. Man is disclosed in behavioral data, but his face and freedom are concealed. Thus, the root of the later critique of technology can be seen in this initial analysis of truth. The main question is always: how are beings disclosed, and what is concealed in this disclosedness?
From the perspective of “Being and Time”, authentic Dasein is one who takes over its relation to truth in a different way. It no longer lives merely in idle talk and ambiguity. It knows that the everyday world, with all its apparent clarity, can be concealing. Through anxiety, death, conscience, and resoluteness, it reaches a deeper disclosedness toward itself and the world. This disclosedness is not knowing everything and not possessing truth. On the contrary, authentic Dasein knows that truth is always accompanied by concealment. It is more aware of the limitation of its understanding. Thus, authentic truth is accompanied by humility, not by the claim of complete mastery. Authentic Dasein does not “possess” truth; it “stands” in the disclosedness of truth.
This point shows an important difference between Heideggerian truth and Cartesian certainty. Descartes sought a certain foundation that doubt could not shake. Truth in this tradition was linked to the clarity, distinctness, and certainty of the subject. Heidegger, however, links truth to disclosedness and unconcealment, not to the certain possession of the subject. Dasein is not the master of truth nor its absolute starting point. It is “thrown” into truth. The world is disclosed for it prior to any theoretical reflection. This disclosedness makes both knowledge and error possible. Thus, truth for Heidegger is both more fundamental than certainty and more restless than it. Truth is not something once and for all possessed by the subject; it is an event in which disclosedness and concealment are always in tension.
From here one can understand why Heidegger later emphasizes art and poetry. If truth is not merely the correspondence of a proposition with reality, then art can also disclose truth. A work of art may not produce a scientific proposition, but it can disclose a world. Poetry may not give new information, but it can transform our relation to language, earth, death, love, home, or the sacred. This possibility is not fully developed in “Being and Time”, but its foundation is in this understanding of truth. When truth is unconcealment, the ways of truth are not limited to science and propositions. Thought, art, poetry, silence, authentic action, and even a mood like anxiety can be truth-disclosing. This is one of the most important consequences of Heidegger's move beyond the correspondence theory.
Nevertheless, one must again keep the boundaries. That art, poetry, or mood can disclose truth does not mean that science, argument, or propositions are invalid. Each way of disclosedness has its own place. The modern danger, for Heidegger, is that one way of disclosedness, namely calculative and objectifying disclosedness, presents itself as the only truth. But the response to this danger should not be to eliminate science or reason, but to open other horizons of truth. Human truth is multi-layered. The world can be disclosed scientifically, artistically, practically, ethically, religiously, lived-ly, and philosophically. None should simply take the place of all others. Heidegger's understanding of truth makes us sensitive to this plurality of ways of disclosedness.
In conclusion, one can say that the analysis of truth in “Being and Time” is one of the keys to understanding Heidegger's entire project. He does not begin from truth as correspondence, but shows that correspondence is based on fundamental unconcealment. Dasein is in truth because it is disclosed; but because it falls and lives in idle talk and ambiguity, it is also in untruth. Truth is always accompanied by concealment, and philosophy is an attempt to open what has been concealed in everyday obviousness. This understanding of truth transforms our relation to science, language, politics, art, technology, and life itself. Truth is no longer merely a matter of correct propositions; it is a matter of the way the world is disclosed. And because Dasein is a temporal, historical, and caring being, truth occurs in the horizon of time, history, and care.
Thus, “Being and Time”, with its analysis of truth, returns once again to its main question. The question of Being is only possible when we understand how beings are disclosed for Dasein. If we understand truth only as correspondence, we remain blind to this fundamental disclosedness. But if we understand truth as unconcealment, then the question of Being becomes possible again. Being is what is already understood in the disclosedness of beings, but often remains concealed. Therefore, the analysis of truth in “Being and Time” is a way of understanding the forgetting of Being: we know beings correctly, measure them, judge about them, and use them, but we forget the disclosedness of Being itself. Heidegger wants to pull us out of this forgetting; not by adding new information, but by reopening the horizon in which truth, world, and Dasein belong together.
The Incompleteness of the Project of Being and Time: Why Was the Book Never Finished?
“Being and Time” from the very beginning is an incomplete work; not only externally and historically, but also internally and philosophically. The book published in 1927 was intended to be part of a larger project. In the introduction, Heidegger announces a more expansive program: first, the analysis of Dasein on the basis of temporality and the demonstration of time as the horizon for the understanding of Being; then, the phenomenological destruction of the history of ontology, from Kant and Descartes to Aristotle, to reveal how the metaphysical tradition has concealed the question of Being. But what was published was only a part of this project. The book ends at a point where the main promise has not been fully realized. Dasein has been analyzed, care has been revealed as its fundamental structure, temporality has been explained as the meaning of care, historicity and truth have been examined; but the final transition from the temporality of Dasein to the meaning of Being itself, as the project required, is not completed. This incompleteness is one of the main mysteries of “Being and Time”.
First, it must be clear that the incompleteness of “Being and Time” should not be seen merely as an accidental occurrence due to lack of time, work pressure, or publishing difficulties, though external factors were not without influence. The problem is deeper than that. The project itself encounters a fundamental problem at a certain point: can the question of the meaning of Being be fully answered through the analysis of Dasein? At the beginning of the book, Heidegger says that Dasein is the being that has an understanding of Being, so the analysis of Dasein is the way into the question of Being. This path is traversed with great force in the published parts. But as the analysis of Dasein proceeds, it becomes clearer that although Dasein is the horizon for the understanding of Being, Being itself cannot be reduced to the structures of Dasein. The question of Being is larger than the analysis of Dasein. This gap between the way in and the final destination is one of the internal reasons for the incompleteness of the project.
In “Being and Time”, Heidegger still begins from Dasein. He wants to show that every question of Being must necessarily pass through the being that understands Being. But the danger of this method is that the question of Being may remain too dependent on Dasein. If Being is only understood from Dasein's horizon, have we really moved beyond anthropocentrism? Does the analysis of Dasein, however anti-Cartesian and anti-subjectivist, still give a kind of centrality to man? Heidegger himself later became sensitive to this problem. In the later works, he no longer wants to move from Dasein toward Being, but tries to speak from the disclosedness of Being itself, from the event, from the history of Being, and from the ways of Being's disclosedness. For this reason, one can say that the incompleteness of “Being and Time” is a sign of the internal transition of Heidegger's thought: he began with the analysis of Dasein, but the question of Being took him beyond Dasein itself.
This point must be understood in relation to the “turn” (“Kehre”). The turn in Heidegger does not mean a simple abandonment of “Being and Time”. He does not suddenly move from one subject to another. The question remains the same: the question of Being. But the direction of the movement changes. In “Being and Time”, the dominant path is: from Dasein to temporality, and from temporality to the horizon for the understanding of Being. In the later thinking, the path becomes more: from the event of the disclosedness of Being to the place of man in this disclosedness. In other words, the early Heidegger asks how Dasein understands Being; the later Heidegger asks how Being discloses itself and how man is called in this disclosedness. This difference does not invalidate the project of “Being and Time”; rather, it shows that the project was a critical beginning that transformed itself in its continuation.
One of the main difficulties of the book is the relation between the temporality of Dasein and the meaning of Being. Heidegger shows that Dasein is at bottom temporal. Future, past, and present are not three external moments, but three existential horizons of care. Dasein comes toward itself from future possibilities, arises from a thrown past, and is engaged in the present with the world. This analysis is extraordinarily powerful. But the main question was how to move from this temporality of Dasein to the meaning of Being. Is the temporality of Dasein merely the horizon for the understanding of Being for man, or is time in a more fundamental sense the horizon of Being itself? Heidegger in “Being and Time” reaches the threshold of this question, but does not give the final answer. This is where the title “Being and Time” remains a kind of unfinished promise. We understand the temporality of Dasein, but the ultimate relation of Being itself and time has not yet been fully disclosed.
This incompleteness can also be seen from another angle: the part on the destruction of the history of ontology, which was supposed to be the second part of the project, was not realized in the announced form. Heidegger wanted to show how the history of Western philosophy, especially from the Greeks to modern philosophy, has understood Being mainly in the horizon of presence. He intended to push aside the sedimented layers of metaphysics through a rereading of Kant, Descartes, and Aristotle, and to free the question of Being from the cover of traditional concepts. Although Heidegger later returned to Kant, Aristotle, Plato, Hegel, Nietzsche, and the pre-Socratics in many works, that specific project promised in “Being and Time” was not completed in the book itself. Thus, the incompleteness of the book is not only at the level of the analysis of Dasein; it is also at the level of its historical and critical program.
Nevertheless, one must note that “Being and Time”, even in its incompleteness, is a complete work in terms of its influence. Many great works of philosophy are important for their answers; “Being and Time” is important largely for the questions it opened and the path it left incomplete. This book pulled philosophy out of several fundamental obviousnesses: the obviousness of the subject, the obviousness of the world as a collection of objects, the obviousness of truth as correspondence, the obviousness of time as a sequence of nows, the obviousness of man as a rational animal or knowing subject, and the obviousness of death as an event at the end of life. Even if the book did not reach its final promise, the path it traversed was so transformative that philosophy after it could no longer continue in the same way. From this perspective, the incompleteness of “Being and Time” is not a simple weakness; it is part of its power. The book is like a threshold that leads us into a new horizon, even if it does not itself reach the end of that horizon.
The incompleteness of the project is also related to the difficulty of language. Heidegger in “Being and Time” writes in a language that wants to move beyond the language of traditional metaphysics, but is still obliged to use that same language. He constructs new terms, transforms old words, reactivates Greek and German roots, and tries to distance himself from concepts like subject, object, consciousness, substance, soul, and man in their ordinary sense. But the question is whether one can, with the language of philosophy, move beyond the history of philosophy? Are the very words "Being" and "time" still too much within the horizon of the same metaphysics they seek to destroy? Heidegger himself later paid more attention to language, poetry, silence, thoughtful speech, and the non-conceptual possibilities of thinking. Perhaps one of the reasons for the incompleteness of “Being and Time” was that its language, with all its brilliance, was still not sufficient for what Heidegger wanted to say.
In the later works, this linguistic problem becomes more apparent. Heidegger relies less on the analytical and structural language of “Being and Time” and more on words like event, disclosedness, the house of Being, dwelling, the fourfold, “Gestell”, aletheia, the holy, and poetic thinking. This change of language is not a change of subject, but a sign of the difficulty of the same initial question. “Being and Time” wanted to reach the question of Being through the analysis of Dasein, but along the way it showed that the question of Being perhaps requires a language less anthropocentric, less structural, and less dependent on the conceptual tradition of metaphysics. From this perspective, the incompleteness of the book is linked to the crisis of philosophical language. At the end of his initial project, Heidegger confronted the question of whether philosophy, in its traditional sense, is capable of thinking Being.
On the other hand, the incompleteness of “Being and Time” is also related to the question of method. The method of the book is hermeneutical phenomenology. Heidegger wants to show phenomena in such a way that they disclose themselves, and at the same time knows that every understanding is placed in the hermeneutical circle. This method is very fruitful for the analysis of Dasein. But when the question of Being itself is raised, is the phenomenology of Dasein sufficient? If phenomenology always begins from Dasein's disclosedness, can it think the disclosedness of Being itself, prior to its relation to Dasein? This methodological question is one of the main knots of the project. Heidegger later, instead of emphasizing method, spoke more of path, thinking, listening, releasement, and responding to the call of Being. This change shows that he perhaps recognized the limitation of the method of fundamental phenomenology.
Of course, one should not think that Heidegger after “Being and Time” simply moved beyond Dasein and set it aside. Dasein still remains in his thought, but its place changes. In “Being and Time”, Dasein is the main way into the question of Being. In the later works, man is more the place of disclosedness, the shepherd of Being, or the being called in the event of Being. This difference is subtle but important. Dasein is no longer the center of the analysis; it is placed in a larger horizon. If “Being and Time” sometimes appears as if Being is understood from Dasein's horizon, the later Heidegger tries to show that Dasein itself stands in the horizon of the disclosedness of Being. Thus, the incompleteness of the book can be seen as the result of a movement from "the understanding of Being by Dasein" toward "Dasein's being called by Being."
Here the problem of anthropocentrism once again becomes important. “Being and Time” was written against Cartesian subjectivism, but man, or more precisely Dasein, is still the point of departure for the analysis. This point of departure is methodologically justified, because only Dasein is the being for whom the question of Being has meaning. But ultimately, it may not be sufficient. The later Heidegger is concerned that even the analysis of Dasein may unintentionally remain within the horizon of anthropocentrism. He wants to lower man from the position of the grounder of meaning and bring him to the position of the responder to the disclosedness of Being. This change can be seen as a response to the incompleteness of “Being and Time”. The book remained incomplete because, if it had been completed, it would perhaps have had to move beyond its own framework. In other words, the full realization of the project would have required the transformation of the project itself.
Another important point is that the incompleteness of “Being and Time” is also linked to the very concept of time. If Dasein is a temporal, possible, and incomplete being, perhaps a work that tries to understand this being inevitably carries a kind of incompleteness within itself. This should not be a poetic excuse for the book's defects, but it is philosophically meaningful. “Being and Time” speaks of a being that can never be reduced to a full presence and final definition. Dasein is always ahead of itself, comes from a past, and is engaged in a present. Thus, any analysis of Dasein is also subject to disclosedness and incompleteness. A book that tries to define Dasein as a closed and complete system would be inconsistent with the spirit of its own analysis. “Being and Time” in this respect, in its incompleteness, resembles its subject: open, possible, and on the threshold.
Nevertheless, the incompleteness of the book should not prevent a critical evaluation of it. Some critics have said that Heidegger could not realize his main promise; that is, he could not move from the analysis of Dasein to a complete questioning of Being. From this perspective, “Being and Time” is a great but failed work. This criticism should not be ignored. The book indeed does not reach all it promised. But one must ask whether failure in philosophy always means invalidity. Perhaps some failures, if they are honest encounters with the difficulty of the question, are more important than many apparent successes. “Being and Time” may not present a complete system, but it shows that the question of Being is much more difficult than can be easily solved with traditional concepts. This failure, if it is a failure, is a productive failure; a failure that opened new paths in philosophy.
On the other hand, some readers have tried to read “Being and Time” independently of the later incomplete project; that is, not as an incomplete introduction to the question of Being, but as a complete analysis of Dasein, man, authenticity, temporality, and everyday life. Such a reading is to some extent justified, because the book in its published form also has a strong internal structure. The analyses of Being-in-the-world, equipment, the "they," falling, anxiety, death, conscience, care, temporality, and historicity each have their own philosophical value. Many thinkers, from existentialists to phenomenologists, from hermeneutics to literary theory and philosophy of technology, have been inspired by these published parts, without necessarily following the full announced project. Nevertheless, if “Being and Time” is read only as a book about man, there is a danger of forgetting Heidegger's main question. Dasein in the book is not the final goal; it is a way to the question of Being.
Thus, one must maintain a balance between two readings. On one hand, “Being and Time” must be read in the horizon of its incomplete project, because the whole book is directed toward the question of the meaning of Being. On the other hand, one should not measure the value of its analyses of Dasein only by whether the final project was completed. The book, even in its incompleteness, has opened independent and profound horizons. These two levels must be preserved simultaneously. “Being and Time” is both a work about Dasein and a work beyond Dasein; both an analysis of human existence and an attempt to prepare the question of Being; both a complete book in many of its analyses and incomplete in its final promise. Its greatness lies precisely in this tension.
The incompleteness of the book also opened the way for its wide and varied influence. Because the project was not closed and complete, different readings of it emerged. Sartre read it in the horizon of existentialism and human freedom, though Heidegger distanced himself from this reading. Gadamer took inspiration from its hermeneutics of facticity and historicity. Arendt applied its worldhood and Being-with to politics and plurality. Levinas from it developed an ethical critique of ontology. Derrida transformed the incompleteness of Heidegger's overcoming of the metaphysics of presence into deconstruction. Foucault and others took inspiration from its critique of the subject and the history of truth. If “Being and Time” had been a closed system, it might not have had such broad fertility. Its incompleteness allowed each thinker to build a new path from its gaps and open possibilities.
This incompleteness is also important for the reader. Someone reading “Being and Time” should not expect to reach a final and comforting answer at the end of the book. The book leads the reader into a question that the book itself does not fully resolve. This may be frustrating, but it is consistent with the nature of Heidegger's thinking. Heidegger does not want to turn philosophy into a set of ready-made results. He wants to awaken the capacity for questioning. The incompleteness of the book compels the reader to continue the question themselves. For this reason, “Being and Time” is more a book for learning to question than a book for memorizing answers. A serious reader at the end of it may have fewer definite answers than at the beginning, but their questions will have become deeper.
In this context, the difference between "incomplete" and "unsuccessful" is important. A book may be incomplete but not unsuccessful. “Being and Time” is incomplete because it did not complete all its planned parts and did not complete the final transition from the temporality of Dasein to the meaning of Being. But it is not unsuccessful, because it was able to transform the philosophical question from the ground up. Unsuccessfulness would be if the book neither reached an answer nor deepened the question. But “Being and Time”, even with its incompleteness, brought about one of the deepest transformations of contemporary philosophy. Therefore, it must be considered an incomplete but foundational work; a project that did not reach its end, but opened a path through which much of twentieth-century philosophy passed.
From Heidegger's own perspective, one can say that “Being and Time” was an introduction to a deeper confrontation with the forgetting of Being. In this book, the forgetting of Being is raised through the analysis of the metaphysical tradition and the everydayness of Dasein. But in the later thinking, the forgetting of Being acquires broader dimensions in Western history, technology, the metaphysics of presence, and “Gestell”. If “Being and Time” had been completed, it might have been a different book; but because it remained incomplete, it allowed Heidegger to pursue the question in other ways. In this sense, its incompleteness is part of Heidegger's intellectual path, not a mere interruption in it. “Being and Time” did not end, because the question of Being could not end in that initial form. The question itself demanded a new form of thinking.
In conclusion, one can say that the incompleteness of the project of “Being and Time” is one of the most important keys to understanding it. This book began with the question of Being, chose Dasein as the way in, analyzed Dasein's fundamental structures with unprecedented precision, identified care as the unity of these structures, understood temporality as the meaning of care, and explained truth as unconcealment. But at the threshold of the final transition to the meaning of Being, it stopped. This stopping is not merely an external defect, but a sign of the internal difficulty of the project. The analysis of Dasein was necessary, but not sufficient. The question of Being compelled Heidegger to move beyond Dasein, change his language, transform his method, and turn to the history of Being, the event, technology, art, and language.
Thus, “Being and Time” must be read as a book that is alive in its incompleteness. This work brings us to a point where one can no longer return to the philosophy of consciousness, simple anthropology, linear time, truth as correspondence, or the metaphysics of presence. But at the same time, it leaves us before an open question: if the temporality of Dasein is the horizon for the understanding of Being, how should Being itself be thought? The answer to this question is not completed in the book itself, but this very question opens the way to the later Heidegger and much of contemporary philosophy. Therefore, the incompleteness of “Being and Time” is not a margin to the book, but part of its meaning. The book leaves a silence at its end; a silence that does not come from simple failure, but from the magnitude of a question that still calls thinking.
The Place of Being and Time in the Transition to the Later Heidegger
“Being and Time” cannot be read merely as an independent and closed book; it is both the peak of the early period of Heidegger's thought and the threshold of his transition to another stage. Many of the concepts that appear in Heidegger's later works arise from the questions of “Being and Time”, but they do not remain in the same form. Dasein, worldhood, truth as unconcealment, temporality, historicity, the critique of the metaphysics of presence, and the question of the forgetting of Being are all founded in “Being and Time”. But in the later works, the center of gravity of thought shifts. Heidegger relies less on the analysis of Dasein's structures and more on the history of Being itself, language, the event, technology, art, and the possibility of non-metaphysical thinking. This change is usually called the “turn” (“Kehre”); but this turn does not mean abandoning the initial question. The question remains the question of Being, but the way of approaching it changes.
In “Being and Time”, Dasein is the way into the question of Being. Heidegger says that the only being for whom Being is an issue is Dasein; therefore, if we want to ask about the meaning of Being, we must first analyze Dasein's structure. This analysis leads to Being-in-the-world, worldhood, care, death, conscience, resoluteness, temporality, and historicity. But at the end of the book, it becomes clear that the question of Being cannot be limited to the analysis of Dasein. Dasein is the horizon for the understanding of Being, but the disclosedness of Being itself is larger than Dasein. In the later works, Heidegger tries to speak of the event of disclosedness itself; of how Being in different histories has disclosed and concealed itself, and how man is not the owner of this disclosedness, but belongs to it and is called by it. Thus, the Heideggerian turn can be understood as a movement from the methodological Dasein-centrism toward thinking the disclosedness of Being itself.
This change is clearly seen in the concept of truth. In “Being and Time”, fundamental truth is analyzed as Dasein's disclosedness. Dasein is in truth because the world is disclosed for it; and in untruth, because falling, idle talk, and ambiguity conceal this disclosedness. But in the later works, truth as aletheia, that is, unconcealment, moves beyond the scope of the analysis of Dasein. The problem is no longer merely how Dasein stands in the disclosedness of the world, but how Being itself has been disclosed in different ways and simultaneously concealed in the history of the West. Truth is no longer just an existential structure of Dasein; it is the historical event of the disclosedness of Being. This expansion arises from the same analysis that began in “Being and Time”, but now the field is wider. Dasein remains important, but it is no longer the absolute center of the discussion.
The concept of historicity follows a similar path. In “Being and Time”, historicity is the structure of Dasein. Dasein comes from a thrown past, sees its situation in the present, and takes over its possibilities in the horizon of the future. Heritage, repetition, and destiny are understood in this framework. But in the later thinking, Heidegger speaks of the history of Being; that is, of how Being itself has been understood in different ways in different historical epochs. The Greeks, the Middle Ages, the modern age, the metaphysics of the subject, Nietzschean nihilism, and modern technology are for Heidegger not merely intellectual or cultural periods; each is a way of the disclosedness of beings and the concealment of Being. Here historicity moves from the level of Dasein to the level of the history of truth itself. This expansion cannot be understood without “Being and Time”, but it cannot be reduced to it either.
One of the clearest examples of this transition is the critique of technology. In “Being and Time”, Heidegger does not speak directly and extensively about modern technology, but the analysis of equipment, readiness-to-hand, presence-at-hand, and worldhood provides important preparations for the later critique of technology. In that book, equipment has meaning within a network of references and in Dasein's practical world. The hammer, the pen, the table, the house, and the road are not isolated objects; they are understood within the total worldhood of work and dwelling. But in the later works, Heidegger shows that modern technology is not merely a set of tools. Technology is a way of disclosing the world; a way in which beings appear as reserve, resource, data, and exploitable capability. This is what he later calls “Gestell”. In this respect, the later critique of technology is rooted in the question of “Being and Time”: how are beings disclosed for us, and what is concealed in this disclosedness?
The important difference is that in “Being and Time”, the world is still analyzed mainly from the horizon of Dasein and its practical engagement; but in the later critique of technology, the historical way of the disclosedness of beings itself becomes the object of thought. Modern technology is not merely a tool in man's hands, but a way in which man himself is also placed within the system of calculation, production, exploitation, and storage. Man thinks he is the master of technology, but he himself is understood within the technological horizon. This statement is a continuation of the critique of the metaphysics of presence and objectification that began in “Being and Time”. In the first book, Heidegger showed that the theoretical and presence-at-hand view is derived from practical engagement and worldhood; in the later works, he shows how the modern world has transformed one particular way of disclosedness into the dominant and almost exclusive one. Technology from this perspective is the historically final form of the same danger that lay in the forgetting of Being.
Art also acquires a fundamental place in the transition to the later Heidegger. In “Being and Time”, art is not yet the main focus of the discussion, though the analysis of truth as unconcealment prepares the way for an artistic understanding of truth. When truth is not merely the correspondence of a proposition with reality, a work of art can be the place of the event of truth. In the essay "The Origin of the Work of Art," Heidegger shows that the work of art sets up a world and brings forth the earth. The work of art is not merely a beautiful object or a subject of taste; it is a place where truth happens. This thought would not have been possible without the transformation of the concept of truth in “Being and Time”. If truth were only propositional correctness, art would at best be an expression of feeling or a representation of reality. But if truth is unconcealment, then art can be one of the most fundamental ways of the disclosedness of the world. Thus, the path from the truth of Dasein in “Being and Time” to the truth of the work of art in the later Heidegger is opened.
Language also has such a place. In “Being and Time”, discourse is one of the structures of Dasein's disclosedness. Dasein understands the world, this understanding occurs in a specific attunement, and is articulated in discourse. Language here is still mainly analyzed in connection with Dasein. But in the later works, Heidegger approaches his famous saying that language is the house of Being. This does not mean that man merely speaks about Being with language; rather, language is the place where Being can show itself or conceal itself. Man is not the owner of language; he more dwells in language. This change is very important. In “Being and Time”, language is part of Dasein's disclosedness; in the later Heidegger, language itself becomes the horizon of the disclosedness of Being. Man is no longer the primary speaker; he is one who must listen to language and the call of Being.
This development becomes apparent in Heidegger's relation to poetry, especially the poetry of Hölderlin. The later Heidegger sees the poet as one who can open the forgotten possibilities of language and dwelling. Poetry is not merely linguistic ornament or aesthetic feeling; it is a kind of disclosedness of the world. This view of poetry is a continuation of the critique of idle talk and everyday language in “Being and Time”. There Heidegger showed that language can fall into idle talk and become the circulation of rootless public meanings. In the later works, he moves toward another possibility of language: a language that is not concealing, but disclosing; a language that is not merely a tool of communication, but the house of man's dwelling in nearness to Being. Thus, there is a hidden but deep connection between the critique of idle talk in “Being and Time” and the poetic thinking of the later works.
The concept of “dwelling” also arises from this path. In “Being and Time”, Dasein is in the world; the world is its primary home, though anxiety reveals its fundamental homelessness. Dasein always lives in a world of equipment, others, language, and possibilities. But in the later works, the question of dwelling acquires broader dimensions. Heidegger asks how man can dwell on the earth, how he can recover his relation to the sky, the earth, mortals, and the divine, and how modern technology threatens this possibility of dwelling. This discussion appears distant from the analysis of Dasein, but its root is in the same problem of Being-in-the-world. If Dasein is from the start in the world, the later question becomes whether modern man can still “dwell” in the world, or whether the world has become for him merely a resource, a calculable space, and a field of exploitation.
The concept of the “event” (“Ereignis”) is also one of the most important points of difference between the later Heidegger and “Being and Time”. In the first book, the disclosedness of the world is analyzed through Dasein's structures. But in the later thinking, Heidegger tries to speak of an event in which man and Being belong together. The event is that fundamental disclosedness in which Being manifests itself and man finds his place in this disclosedness. This concept is very difficult and should not be reduced to a temporal occurrence or a simple historical event. “Ereignis” is the name of an attempt to think something that is neither made by man nor independent of man in the sense of an external object; rather, it is the relation of mutual belonging of man and Being. If “Being and Time” asked how Dasein understands Being, the thinking of the event asks how man and Being come to belong together in historical disclosedness.
From this perspective, the later Heidegger is an attempt to move beyond the remnants of anthropocentrism in “Being and Time”. In the first book, although Dasein is not the Cartesian subject, it is still the center of the analysis. But in the later works, Heidegger wants to show that man is not the grounder of truth. Man is the place where truth can occur, but this occurrence is not in his complete control and possession. He must listen, care, let go, and remain in nearness to Being. This change moves from the language of will, decision, and resoluteness to the language of letting-go, listening, and dwelling. Of course, this transition itself is a subject of critique, because it may distance itself from human action and responsibility. But internally, it is a continuation of the same attempt to move beyond the metaphysics of the subject that began in “Being and Time”.
This problem is also seen in relation to humanism. In the “Letter on Humanism”, Heidegger explicitly tries to show that his thought should not be reduced to ordinary humanism. Humanism, in his view, however much it appears to elevate the dignity of man, usually defines man still within the horizon of metaphysics: the rational animal, the subject, the person, the spirit, the will, or the center of meaning. Heidegger wants to understand man's dignity in another way: man is the being who stands in the disclosedness of Being and can either preserve or forget his relation to Being. This statement is a continuation of the critique that began in “Being and Time” of defining man as a subject or rational animal. But in the later works, this critique moves beyond the level of the analysis of Dasein and becomes a critique of the entire tradition of metaphysical humanism.
Nevertheless, the transition to the later Heidegger does not solve all the problems of “Being and Time”. Some critics have said that the later Heidegger, by distancing himself from Dasein, approaches a language that is too poetic, vague, and sometimes irresponsible. In “Being and Time”, although the language is difficult, the analyses are still largely phenomenological and traceable. We can follow the experience of equipment, everydayness, anxiety, death, conscience, and temporality in Dasein's life. But in the later works, concepts like the event, the history of Being, the fourfold, and “Gestell” sometimes become so broad and poetic that the danger of ambiguity arises. This criticism is important. The transition from Dasein to Being, if not accompanied by precision, can become a language that offers less possibility of testing and dialogue. Thus, the later Heidegger is both a continuation of “Being and Time” and a new problem for the reader.
On the other hand, some believe that this very transition saved Heidegger from the existentialist and anthropocentric limitations of “Being and Time”. If he had remained in the analysis of Dasein, his thought might have been reduced to a philosophy of individual authenticity, death, anxiety, and choice; what happened in some existentialist readings. But Heidegger wanted to go beyond this. He did not want to speak only about man; he wanted to think the history of Being itself. From this perspective, the later works are not a deviation, but a deeper fidelity to the initial question. “Being and Time” opened the way, but if Heidegger had remained within its framework, the question of Being might have been trapped again in philosophical anthropology. The turn was an attempt to free the question of Being from even the subtlest forms of anthropocentrism.
In this context, one must also see the relation of “Being and Time” to nihilism and Western metaphysics. In “Being and Time”, the critique of metaphysics proceeds mainly through the analysis of traditional ontology and the forgetting of the question of Being. But in the later works, Heidegger understands nihilism as the historical fate of Western metaphysics; that is, a situation in which beings are entirely understood in the horizon of will, value, calculation, and technology, and Being itself is more forgotten than ever. Nietzsche here acquires an important place, because Heidegger sees him not merely as a critic of metaphysics, but as the last metaphysician of the West. This later critique of nihilism is incomprehensible without the initial question of “Being and Time” about the forgetting of Being. “Being and Time” raised the problem at the level of fundamental questioning; the later works extended it to the history of the West and the technological fate of the modern world.
One must also note that the later Heidegger increasingly uses the language of "thinking" against "philosophy." Philosophy, especially in its metaphysical form, is for him part of the history of the forgetting of Being. Thinking, however, is something that tries to listen to what philosophy has concealed. This distinction is rooted in “Being and Time”, because that book also begins with the phenomenological destruction of the tradition of philosophy. But in the later period, this distinction becomes more pronounced. Heidegger no longer wants only to build a new philosophy; he wants to prepare the possibility of another thinking. A thinking that neither builds systems, nor transforms beings into objects of control, nor makes man the grounding subject, nor reduces truth to propositional correctness. This other thinking, in the later works, sometimes approaches poetry, silence, and waiting.
This development is the subject of much debate from a political and ethical perspective. Some critics say that Heidegger, by moving toward the language of the event, the destiny of Being, and the history of Being, distances himself from specific human and political responsibilities. If everything is understood in the horizon of the history of Being and “Gestell”, what place is left for action, responsibility, justice, and resistance? This critique is especially important in light of Heidegger's political errors. “Being and Time” is also not completely free from this problem, because resoluteness and destiny in it can remain ambiguous. But in the later works, the danger of a kind of historical fatalism increases. Therefore, a responsible reading of Heidegger must preserve both the depth of his critique of technology and metaphysics, and not let the language of the history of Being replace specific ethical, political, and social analysis.
Nevertheless, one cannot deny that the transition from “Being and Time” to the later Heidegger is one of the most important paths of twentieth-century philosophy. This transition shows that the question of man, if pursued deeply, leads to the question of the world, truth, history, language, and technology. “Being and Time” began with Dasein, but Dasein found itself in a world that goes beyond it. Worldhood led to truth, truth to history, history to the forgetting of Being, and the forgetting of Being to the critique of technology and language. Thus, between the early and later Heidegger there is neither an absolute rupture nor a simple continuity. It is better to say that Heidegger's thought pursues the same question in progressively deeper and broader horizons. “Being and Time” is the first great form of this question; the later works are its other forms.
To understand this relation correctly, one must avoid two common errors. The first error is to consider “Being and Time” as Heidegger's only important work and to regard the later works as a poetic or vague deviation. This view does not see that many later concepts are rooted in the unresolved questions of that book. The second error is to elevate the later works so much that “Being and Time” appears only as an immature and insufficient stage. This is also incorrect, because without the analysis of Dasein, worldhood, truth, temporality, and historicity in “Being and Time”, the later Heidegger loses its foundation. The correct relation is to consider “Being and Time” both as an independent and foundational work, and as a threshold for passing to the later questions. This book is neither all of Heidegger nor merely a passing introduction; it is the initial heart of a path that later transforms.
Ultimately, the place of “Being and Time” in the transition to the later Heidegger can be understood as follows: this book pulled the question of Being out from under the domination of subject, object, presence, linear time, and propositional truth. But this same liberation brought the question to a level where the analysis of Dasein was no longer sufficient. Heidegger was compelled to move from Dasein to the history of Being, from the truth of Dasein to the unconcealment of Being, from equipment to “Gestell”, from discourse to language as the house of Being, from worldhood to dwelling, and from resoluteness to letting-go and listening. This movement is not an abandonment of “Being and Time”, but a continuation of its internal crisis. The first book opened the way, but the way itself took Heidegger to a place where he had to move beyond its initial framework.
In conclusion, one can say that “Being and Time” is like a gateway through which all of Heidegger's later thinking passes. Anyone who wants to understand the later Heidegger must necessarily return to this book; and anyone who seriously reads “Being and Time” will sooner or later encounter questions that lead to the later works. Dasein, care, and temporality lead us to truth, history, and Being; truth and history lead us to technology, art, and language; and all of these return us to the initial question: what is Being, and why has this question been forgotten in the history of philosophy? “Being and Time” awakened this question in an unprecedented way. The later Heidegger tried to continue listening to this same question in the silences, poems, events, and dangers of the modern world.
The Principal Criticisms of Being and Time: Grandeur, Ambiguity, and Limitations
From the very beginning, “Being and Time” was a work that aroused both great admiration and serious objections. Few books in twentieth-century philosophy have been able to transform the horizon of questioning to such an extent, and at the same time, to be so much a subject of ambiguity, misunderstanding, and critique. The grandeur of the book lies in its having pulled philosophy out of many sedimented obviousnesses: man understood not as a knowing subject but as Dasein; the world not as a collection of objects but as the meaningful horizon of Being-in-the-world; truth not merely as correspondence but as unconcealment; time not as a sequence of nows but as existential temporality; death not as an event at the end of life but as Dasein's ultimate possibility; and everyday life not as a worthless surface but as the field where Dasein's fundamental structures are revealed. Nevertheless, this very theoretical power also contains its own dark and problematic points. “Being and Time” is a book from which one must both learn and remain questioning.
The first major criticism concerns the “conceptual ambiguity” of the book. Heidegger deliberately breaks with common philosophical language, because he believes that the traditional language of philosophy was formed in the horizon of the metaphysics of presence and cannot properly express the question of Being. He constructs new terms like Dasein, Being-in-the-world, readiness-to-hand, presence-at-hand, care, falling, the "they," temporality, historicity, and resoluteness, or uses them in new senses. This linguistic innovation is necessary on one hand, because the book wants to move beyond old frameworks. But on the other hand, this very language sometimes becomes so compressed, multi-layered, and difficult that it opens the way to ambiguity and conflicting interpretations. The reader sometimes does not know whether Heidegger is describing existential structures, proposing a kind of practical philosophy, criticizing modern culture, or preparing a question beyond man. This multi-layeredness is part of the book's power, but it is also one of the sources of its difficulty and danger.
The ambiguity of Heidegger's language is not just a stylistic issue; it relates to the project itself. Heidegger wants to speak of man, but does not want to write anthropology. He wants to speak of experiences like anxiety, death, conscience, and everydayness, but does not want to write psychology or ethics. He wants to analyze history and heritage, but does not want to present a classical philosophy of history. He wants to redefine truth, but does not want simply to set aside logic and propositional correctness. This intermediate position means that the book constantly moves at the border of several fields. This borderline nature sometimes leads the reader into error. Some have understood “Being and Time” as an existentialist book about man; some as an introduction to the critique of metaphysics; some as fundamental ontology; some as a work about time; and some as a book about the crisis of modernity. All these readings contain part of the truth, but none alone is sufficient.
The second criticism concerns the “incompleteness” of the project. Heidegger promises to move from the analysis of Dasein to the question of the meaning of Being and then to carry out a phenomenological destruction of the history of ontology. But the published book does not complete this program. The main promised parts were not written or published, and the final transition from the temporality of Dasein to the meaning of Being itself remains incomplete. In this respect, one can say that “Being and Time” fails in the realization of its announced promise. Of course, this failure is productive and opens the way to the later Heidegger; but it must still be taken seriously. If the book was to clarify the meaning of Being in the horizon of time, did it actually do so? Or did it show more how Dasein is temporal? This question is one of the most fundamental criticisms of the book. “Being and Time” has a title that speaks of the relation between Being and time, but in the published text, the relation of Dasein and time is much clearer than the relation of Being itself and time.
The third criticism concerns the “hidden anthropocentrism” of the book. Heidegger distances himself from Descartes, subjectivism, and the philosophy of consciousness, and shows that Dasein is not a subject separate from the world. Dasein is from the start in the world, with others, and in history. Nevertheless, the question of Being still begins from Dasein. Dasein is the being that understands Being and therefore is the way into fundamental ontology. This point of departure is methodologically defensible, but does it completely move beyond anthropocentrism? Does Being still remain in the horizon of Dasein's understanding? The later Heidegger himself became sensitive to this danger and tried to move beyond the centrality of Dasein. But in “Being and Time” itself, this tension remains. The book is both against subjectivism and unavoidably begins from a human point of departure. This very tension is one of the reasons for the later transition to the history of Being and the event.
The fourth criticism concerns the “underrepresentation of the body”. Dasein in “Being and Time” is in the world, uses equipment, is with others, fears, becomes anxious, dies, and lives in various situations; but his bodiliness is not directly and extensively analyzed. Man in the world is always bodily. Hand, gaze, movement, fatigue, illness, pleasure, pain, gender, age, disability, hunger, and physical vulnerability all play a role in the way of Being-in-the-world. When we use equipment, our body is present in the field of action. When we fear the world or are in anxiety, this mood does not occur only at an abstract level; the body is also involved. When we are with others, our relation is always formed through the body, voice, face, distance, and physical presence. Nevertheless, “Being and Time” does not develop the body to the extent its place in human existence warrants. Later phenomenologists, especially Merleau-Ponty, precisely from this point opened another path and showed that Being-in-the-world is incomprehensible without bodiliness.
The fifth criticism concerns the “problem of the other and ethics”. Through the concept of Being-with, Heidegger shows that Dasein is never an isolated individual and lives from the start in a shared world with others. This analysis is very important for moving beyond the Cartesian problem of "proving the existence of other minds." But the other in “Being and Time” is mainly analyzed within the horizon of Dasein's structures, the shared world, the "they," and solicitude. The other appears less as a face that calls me to ethical responsibility. Heidegger speaks of “Fürsorge”, that is, solicitude or care toward the other, and distinguishes between inauthentic and authentic forms, but this discussion does not become a complete ethics. Levinas later criticized Heidegger from this point and said that ontology, if it takes priority over responsibility toward the other, may absorb the other into my horizon of understanding. For Levinas, the relation to the other is prior to ontology and the foundation of ethics. This criticism shows that “Being and Time” is very strong in the analysis of Being-with, but incomplete in the analysis of ethical responsibility toward the other.
The sixth criticism concerns “politics”, and this criticism gains special importance in light of Heidegger's own life and political positions. In “Being and Time”, concepts like resoluteness, destiny, heritage, repetition, and shared destiny are present. These concepts are designed at an ontological level and should not be simply reduced to a specific politics. But their ambiguity can be dangerous. Resoluteness, if understood without ethical criteria, public dialogue, and responsibility toward the other, may become decisionism; that is, the idea that what matters is the decisiveness of the decision, not its ethical and rational content. Destiny and shared destiny, if used uncritically, can approach the language of closed collectivism, ethnicism, or political myth. “Being and Time” is not in itself a specific political ideology, but some of its concepts require critical care. Heidegger's political error in the 1930s has made this care not an external sensitivity, but a necessity in reading the text itself.
Of course, one should not reduce the whole of “Being and Time” to Heidegger's politics because of his political error. Such a reduction is philosophically incorrect. The book was written before Heidegger's overt political involvement, and its structure is far beyond a specific political position. But on the other hand, one cannot be completely indifferent and suppose that philosophy has no relation to that error. The difficult question is whether in concepts like resoluteness, historical destiny, critique of the "they," anti-everydayness, and the language of heritage, there were possibilities that later approached the political error? The answer is not simple. But a responsible reading must examine this possibility. The philosophical grandeur of “Being and Time” does not prevent its political critique; on the contrary, the greater the work, the greater the responsibility of critical reading.
The seventh criticism concerns the “lack of social and institutional analysis”. Heidegger analyzes everydayness, the "they," idle talk, curiosity, and ambiguity with astonishing precision. But these phenomena are examined more as existential structures of Dasein than as phenomena organized in institutions, media, economics, power, education, and politics. In the real world, the "they" are not merely a vague and nameless force; there are specific social mechanisms that produce, direct, and stabilize public understanding. Media, states, markets, universities, communication networks, advertising, and educational systems all play a role in constructing what "everyone says." Heidegger sees the existential structure of this lostness, but he does not sufficiently develop its institutional and social analysis. Therefore, to understand the modern world, one must supplement “Being and Time” with social theory, critique of ideology, and analysis of power.
The eighth criticism concerns the place of “gender, class, power, and historical differences”. Dasein in “Being and Time” is analyzed at a very general level. This generality has the advantage that the book wants to reveal the fundamental structures of human Being. But this same generality can obscure real differences among humans. Not all Daseins have the same possibility of resoluteness. Class conditions, gender, race, colonialism, political oppression, poverty, illness, and violence can limit the horizon of Dasein's possibilities. Death is the ultimate possibility for all, but the way of confronting death in conditions of war, poverty, discrimination, or illness is not the same as in the calm conditions of everyday life. Temporality has an existential structure for all Daseins, but the future is not opened equally for all. Historicity gives heritage to all humans, but some heritages are accompanied by wounds, erasure, or oppression. “Being and Time” does not sufficiently incorporate these differences into its analysis. Thus, although Heidegger's analysis is fundamental, it is not sufficient for understanding the historical and social life of man.
The ninth criticism, from Hannah Arendt and some other thinkers, concerns the “focus on death”. Heidegger analyzes Dasein as a being-toward-death and understands death as Dasein's distinctive, non-transferable, and ultimate possibility. This analysis is very profound and shows how finitude shapes life from within. But is man only toward death? Arendt, against this focus on death, emphasizes “natality”. Man is not only a being who dies, but is born and can begin. Politics, action, and freedom acquire meaning in the horizon of birth and beginning. From this perspective, “Being and Time” focuses too much on individual finitude, death, and the individualization of Dasein, and less on beginning, collective action, plurality, and the shared political world. This criticism is very important, because it shows that if authenticity is understood only in the horizon of death, the creative, initiating, and political dimension of man may be obscured.
The tenth criticism concerns Heidegger's relation to “theology and religion”. In “Being and Time”, Heidegger tries to present a pre-religious and ontological analysis. He does not discuss God, immortality, salvation, or life after death in a theological sense. But many concepts of the book, such as guilt, conscience, call, falling, authenticity, and death, have clear theological burdens in the Christian tradition. Heidegger extracts these concepts from their theological context and transforms them into existential structures. This is on one hand very creative, because it rereads traditional concepts in a philosophical horizon. On the other hand, one can ask whether these concepts are completely separated from their theological context. Does existential guilt, the call of conscience, and falling, without being explicitly religious, still carry the trace of Christianity? This question is important in theological and anti-ontological readings of Heidegger. “Being and Time” is neither a religious book nor simply secular in a superficial sense; it moves in a complex border between theological heritage and existential philosophy.
The eleventh criticism concerns the danger of “romanticizing authenticity”. Authenticity in “Being and Time” means taking over one's own possibility in the horizon of death, conscience, and resoluteness. This concept is very powerful, but if understood simplistically, it may become a kind of praise of the exceptional individual, firm decision, or anti-everyday life. Heidegger himself emphasizes that authenticity does not mean leaving the world or despising everyday life. Authentic Dasein still lives in the world, with others, and in everyday tasks. But the language of the book sometimes links inauthenticity with the "they," everydayness, idle talk, and dispersion, and links authenticity with death, anxiety, conscience, and resoluteness. This opposition can lead the reader to the misunderstanding that ordinary, collective, and everyday life is essentially inferior to exceptional moments. To prevent this misunderstanding, one must emphasize that authenticity is not a negation of everydayness, but a transformation of the relation to it. Nevertheless, Heidegger's text does not always keep this boundary sufficiently clear and safe.
The twelfth criticism concerns the problem of “rationality and dialogue”. Heidegger distances himself from the tradition of the philosophy of consciousness and theoretical rationality, and shows that understanding occurs prior to theory, in the world and in Dasein's mood. This critique is very important. But in “Being and Time”, the place of rational dialogue, public argument, mutual understanding among Daseins, and reciprocal critique is not very prominent. Habermas and others have criticized Heidegger from this angle, arguing that he neglects the communicative horizon of rationality and instead emphasizes existential disclosedness, resoluteness, and historicity. If Dasein is always with others, should not language be not only the place of idle talk or existential disclosedness, but also the field of critical dialogue? Can authenticity be complete without accountability before others and without communicative rationality? “Being and Time” does not give a sufficient answer to this question. Therefore, to supplement Heidegger, one must take the problem of dialogue, critique, and the public sphere more seriously.
The thirteenth criticism concerns the problem of “science”. Heidegger shows that the theoretical and scientific view of the world is not the most fundamental way of man's encounter with the world. Prior to seeing things as objects of theoretical knowledge, we deal with them in a practical and instrumental world. This analysis is a necessary critique of scientism and theory-centrism. But if read without care, it may lead to an anti-scientific misunderstanding. Heidegger is not anti-science; he wants to clarify the ontological place of science. Science is one way of disclosing beings, not the whole truth. Nevertheless, his sharp language against the domination of the theoretical view and his later critique of technology have sometimes provided grounds for anti-scientific readings. A responsible reading must say that science is limited, but not without value; scientific truth is important, but not the only form of truth. This balance is sometimes difficult in Heidegger himself and requires precise interpretation.
The fourteenth criticism concerns the relation of the book to “affective life and positive human experiences”. “Being and Time” begins with fundamental mood and considers anxiety one of the most important ways of Dasein's disclosedness. Death, guilt, falling, and homelessness are also central concepts. But experiences like love, joy, hope, friendship, gratitude, creation, play, everyday care, and trust do not have a very prominent place. Of course, some of these experiences can be interpreted within the framework of care and Being-with, but the book itself does not bring them to the center. This makes the picture of Dasein in “Being and Time” sometimes appear heavy, dark, and too focused on death and anxiety. Human life is not only disclosed in the confrontation with death and anxiety; sometimes in love, birth, forgiveness, creativity, and joy, a fundamental truth of Being is also disclosed. These are areas that can supplement Heidegger's analysis.
Despite all these criticisms, one must avoid simple judgment. “Being and Time” is not a book that can be either entirely accepted or entirely rejected. Its grandeur lies precisely in the fact that even the criticisms leveled against it often arise from a horizon that the book itself has opened. When we speak of the body, the other, history, language, politics, death, truth, time, everydayness, or technology, in many cases we are involuntarily moving in a field that Heidegger has transformed. Levinas's critique of the priority of ontology, Arendt's critique of the focus on death, Merleau-Ponty's critique of the lack of the body, Habermas's critique of the lack of communicative rationality, and the political critiques of resoluteness and destiny all show that “Being and Time” is not just a book alongside other books; it is a field with which later discussions must inevitably clarify their relation.
Thus, the best way to confront “Being and Time” is neither unconditional praise nor complete rejection. It must be read as a foundational but incomplete work, in need of supplementation. Heidegger taught us that man should not be reduced to a knowing subject, but we must take the body and the other more seriously than he did. He showed that truth is not only correspondence, but we must also preserve propositional correctness and responsibility toward reality. He revealed Dasein's temporality, but we must extend social, historical, and political time. He understood death as Dasein's distinctive possibility, but we must also add birth, love, beginning, and collective action. He criticized everydayness and the "they," but we must also analyze institutions, power, and economics. He raised heritage and historicity, but we must control the political dangers of the language of destiny. In this sense, “Being and Time” is not an end point; it is the beginning of a great dialogue.
It is important that the critique of Heidegger should not be made from the position of a simple return to pre-Heideggerian philosophy. After “Being and Time”, one cannot simply return to the Cartesian subject, truth as mere proposition, linear time, simple anthropology, or the world as a collection of objects. Effective critique must move from a level that Heidegger himself opened. For example, the critique of bodiliness should not again make the body a natural object alongside the mind, but should understand the body in the horizon of Being-in-the-world. The critique of ethics should not just place moral law outside ontology, but should rethink the relation of the other and disclosedness. The critique of politics should not just reject decisionism, but should show how Being-with, the shared world, and historicity can be linked to collective and democratic responsibility. Such critique is a continuation of thinking, not a return to previous obviousnesses.
Ultimately, “Being and Time” can be considered a work that opens as much as it leaves incomplete. This book opens the world to new questions, but does not give final answers. It brings man out of old frameworks, but does not explore all dimensions of man. It moves truth beyond correspondence, but creates the danger of ambiguity. It transforms history from dead past to living heritage, but brings the language of destiny close to danger. It turns death into the horizon of authenticity, but leaves birth and action in the background. It is precisely these tensions that have kept the book alive. Simpler works may provoke less criticism, but also open less. “Being and Time” is great, so it is also dangerous; and because it is dangerous, it must be read with care, courage, and responsibility.
In conclusion, one can say that the main criticisms of “Being and Time” are necessary not to diminish the value of the book, but for its more precise understanding. A book that revived the question of Being must itself remain the subject of questioning. Heidegger wakes us from the sleep of obviousness, but we should not let Heidegger himself become a new obviousness. True fidelity to “Being and Time” is not the repetition of its words; it is the continuation of its questions. We must learn from Heidegger that man is in the world, temporal, historical, caring, and finite; but we must also move beyond his limitations and add the body, the other, justice, politics, birth, power, and dialogue to the analysis. Only in such a reading does “Being and Time” become not a sacred and closed text, but a living source for thinking.
Final Conclusion: Being and Time as the Reawakening of the Question of Being
“Being and Time” must be considered one of the greatest attempts in contemporary philosophy to return philosophy to its most fundamental question: the question of Being. The greatness of this book lies not only in its introduction of new concepts into philosophy or its influence on movements such as phenomenology, existentialism, hermeneutics, deconstruction, the philosophy of technology, and literary theory; its main greatness lies in its showing that philosophy, prior to any theory of knowledge, ethics, politics, science, history, or man, must once again ask itself the meaning of "Being." Heidegger with rare courage declared that the history of Western philosophy, for all its splendor, has forgotten the question of Being. Philosophers have spoken of beings, causes, substances, ideas, God, soul, nature, subject, object, reason, history, and values, but Being itself—that horizon in which every being is understood as a being—has sunk into obviousness and remained concealed. “Being and Time” is an attempt to break this obviousness.
Heidegger's point of departure, unlike many traditional metaphysics, is not an abstract principle, not God, not nature, not the pure subject, not pure consciousness, and not the world as a collection of objects. He begins from “Dasein”; from that being for whom Being is an issue. This choice may appear anthropological, but Heidegger's goal is not anthropology. Dasein is not the final subject of the book, but the way into the question of Being. Because Dasein already has a pre-understanding of Being, however vague, pre-theoretical, and everyday, the analysis of Dasein can bring us closer to the horizon of the question of Being. From here begins one of the philosophical revolutions of “Being and Time”: man is understood not as a rational animal, not as a knowing subject, and not as a psychological substance, but as “Being-in-the-world”. Dasein is always in a meaningful, historical, linguistic, and shared world; a world that is disclosed prior to any theory, in action, equipment, relation, mood, and possibility.
The analysis of Being-in-the-world shakes the foundations of many classical dualisms of modern philosophy. Heidegger shows that man is not first an inward subject that then tries to reach the external world. The world is not something placed before the subject, with knowledge as a bridge between them. Dasein is from the start “in” the world. The world is also not merely a collection of present objects, but a network of meanings, references, equipment, tasks, roles, and possibilities. The hammer, prior to being an object with physical properties, is something for hammering; the table is something for writing or sitting; the house is a place for dwelling; the road is a way for going; language is a horizon for understanding and making understood. This practical and meaningful world exists prior to the theoretical view. Thus, theoretical knowledge is not the beginning of man's relation to the world, but a derivative form of Dasein's more fundamental engagement with the world.
From this analysis emerges Heidegger's critique of the “metaphysics of presence” in the Western tradition. Metaphysics has often understood beings on the basis of presence, stability, thingness, and theoretical knowability. But Dasein cannot be understood as a present object. Dasein is a being that is always ahead of itself in its possibilities, comes from a thrown past, is engaged with the world and others, flees from itself, is called to itself, and in the horizon of death experiences its finitude. Thus, Dasein's Being is not fixed presence, but temporal possibility. With this analysis, Heidegger moves philosophy from fixed essence to possibility, from the isolated subject to Being-in-the-world, from linear time to temporality, and from propositional truth to unconcealment. “Being and Time” for this reason is not merely a book about man, but a fundamental critique of the metaphysical horizon of the West.
One of the deepest achievements of the book is the analysis of “everyday life”. Heidegger shows that Dasein is initially and for the most part not in an authentic, heroic, or contemplative state; it is in everydayness. It is scattered in the "they," in public talk, in habits, in tasks, in ready-made interpretations, and in the shared world. This analysis, despite its appearance, is not a contempt for everyday life. Heidegger considers everydayness the field where Dasein's fundamental structures are revealed. But in this very everydayness, Dasein usually distances itself from its own distinctive possibility. The "they" tell it what to do, what to say, what to fear, what is valuable, how to live, and how to understand death. In this public world, Dasein finds comfort, but this comfort often comes at the cost of getting lost in inauthenticity.
The analysis of “idle talk”, “curiosity”, and “ambiguity” is one of the most contemporary parts of “Being and Time”. Heidegger wrote at a time when the digital world, social networks, the attention economy, and the instantaneous circulation of information did not yet exist, but he described a structure that today appears perhaps more than ever. Idle talk is the circulation of talk without root in an authentic encounter with things. Curiosity is the restless desire to see novelties without pausing and abiding with anything. Ambiguity is the situation in which everything appears understood, but the boundary between understanding and merely hearing has disappeared. These three phenomena show that untruth is not always in darkness and ignorance; sometimes it is hidden in superficial brightness, abundant information, and endless talk. Man may speak about everything, but have authentically encountered nothing.
Against this everyday falling, “anxiety” opens a path of rupture. Anxiety for Heidegger is not fear of something specific; it is a mood in which the whole everyday world loses its obviousness. Things are still there, others are still there, tasks and roles still exist, but their calm and familiar meaning recedes. In anxiety, Dasein confronts its own fundamental homelessness. It realizes that the "they," ready-made interpretations, social roles, and everyday occupations cannot ultimately lift the burden of its Being from its shoulders. Anxiety does not separate Dasein from the world to make it worldless; it separates it from “lostness” in the world so that the possibility of authentic Being in the world can be opened. In anxiety, Dasein understands that its Being is an issue.
This issue reaches its peak in the analysis of “death”. Being-toward-death is one of the most fundamental concepts of “Being and Time”. Death for Heidegger is not merely the biological end of life, but Dasein's distinctive, ultimate, non-transferable, and unsurpassable possibility. The "they" make death public and say that everyone dies; but this public truth can conceal the existential truth of death. My death is not something another can take over in my place. The authentic understanding of death pulls Dasein out of the anonymity of the "they" and shows it that its life also cannot be entirely surrendered to others. Death from this perspective is not the negation of life; it is the horizon for life becoming serious. Because Dasein is finite, its possibilities have weight. Because its time is not endless, choice has meaning. Because death is non-transferable, its Being must also become its own.
But Heidegger does not stop at death. The call of “conscience”, “existential guilt”, and “resoluteness” show how Dasein can be called to its own possibility. Conscience in “Being and Time” is not ordinary moral voice or a set of social rules; it is a silent call that pulls Dasein out of the idle talk of the "they" and returns it to itself. This self is not a fixed substance or ready-made identity; it is a possibility that must be taken over. Existential guilt also does not mean a specific moral error, but the incomplete, thrown, and indebted structure of Dasein. Dasein did not choose its beginning, is not the absolute ground of itself, but must take over its possibilities in a world into which it was thrown. Resoluteness is the authentic response to this call: Dasein's responsible openness to its own possibility in its specific, historical, and finite situation.
In the concept of “care”, Heidegger brings all these structures into unity. Care is the name for Dasein's fundamental structure. Dasein is a being whose Being is an issue for itself. It cannot cut off its relation to its Being; even flight from itself, entertainment, falling, and indifference are forms of having a relation to Being. Care means that Dasein is always ahead of itself, because it lives with its future possibilities; already in a world, because it is thrown and heritage-laden; and alongside beings, because it is engaged in the present with the world, equipment, others, and tasks. From here it becomes clear that care is essentially “temporal”. Dasein is not “in” time; Dasein “is” temporal. Future, past, and present are not three external containers, but three existential horizons of care.
“Temporality” is the hidden heart of “Being and Time”. Heidegger shows that fundamental time is not clock and calendar time, but the temporality of Dasein. The future for him has priority, because Dasein understands itself from its possibilities. The past is not merely something over and done with, but Dasein's thrownness, heritage, and facticity. The present is not a mathematical point, but Dasein's way of being engaged with the world. In authentic temporality, Dasein from its death-aware future takes over its past and in the moment sees its situation. This analysis moves time from the level of measurement to the level of Being. Man does not merely “calculate” time; man lives with possibility, heritage, expectation, decision, death, memory, and situation. Thus, the crisis of time in the modern world is not just a lack of time; it is the loss of an authentic relation to temporality.
“Historicity” is a continuation of this temporality. Dasein never begins from point zero. It lives in a language, tradition, history, body, institutions, and heritages that existed before it. The past for it is not just behind; it is present in its present and future possibilities. But Dasein is not condemned to blind repetition of the past. Authentic historicity means taking over heritage as “possibility”, not worshipping the past nor rootlessly breaking from it. Authentic repetition is not the dead reproduction of tradition; it is the retrieval of the concealed possibilities of the past in the horizon of the future. Nevertheless, this part of Heidegger's thought requires critical care, because concepts like heritage, destiny, and shared destiny, if understood uncritically, can become the language of political myth or closed identity. A responsible reading must understand historicity as the critical taking-over of heritage, not submission to fate.
The analysis of “truth” in “Being and Time” is also one of the foundations of Heidegger's thought. Truth, prior to being the correspondence of a proposition with reality, is “unconcealment” and “disclosedness”. A proposition can only be true or false if a world has already been disclosed and something in it has appeared “as” something. Thus, propositional truth is based on a more fundamental truth. Dasein is in truth because the world is disclosed for it; but it is also in untruth because this disclosedness is always accompanied by concealment, falling, idle talk, and ambiguity. This analysis opens the way to the later Heidegger's thinking about art, language, technology, and the history of Being. If truth is unconcealment, then science, art, poetry, technology, and politics each are a way of disclosing the world; and in every disclosedness, something also remains concealed.
Nevertheless, “Being and Time” is an “incomplete” work. Heidegger was able to analyze Dasein, identify care as its fundamental structure, understand temporality as the meaning of care, and return truth to unconcealment; but the final transition from the temporality of Dasein to the meaning of Being itself was not completed. This incompleteness is not merely an external defect; it is a sign of the internal difficulty of the project. The question of Being begins with the analysis of Dasein, but does not end in Dasein. This very incompleteness led Heidegger to the later turn: from the analysis of Dasein to the history of Being, from the disclosedness of Dasein to the event of the disclosedness of Being, from equipment to “Gestell”, from discourse to language as the house of Being, from worldhood to dwelling, and from propositional truth to historical unconcealment. “Being and Time” is not the end of Heidegger's path; it is the threshold of a path that continues in the later works.
The criticisms of “Being and Time” must also be taken seriously. The book has limitations in its analysis of bodiliness, gender, class, power, institutions, politics, justice, love, birth, and collective action. The other in it appears mostly in the horizon of Being-with and solicitude, rather than as a face that calls me to ethical responsibility. Resoluteness and destiny, if understood uncritically, can lead to decisionism or the dangerous language of historical fate. The focus on death, however profound, must be supplemented by birth, beginning, and shared action. Truth as unconcealment, however much it expands the horizon of philosophy, should not lead to indifference toward propositional correctness and historical reality. Thus, true fidelity to “Being and Time” is not its unquestioning repetition; it is the continuation of its questions along with a critique of its limitations.
Ultimately, “Being and Time” must be considered a book that awakens philosophy from the sleep of obviousness. This book teaches us that the closest things are often the most concealed: the world, time, death, truth, language, others, history, and one's own Being. We live in the world, but take it for granted. We measure time, but forget our own temporality. We speak of death, but do not understand our own death as our own distinctive possibility. We seek truth in correct propositions, but ignore the disclosedness on which every correctness is based. We live with others, but get lost in the "they." We study history, but do not take over our own historicity. “Being and Time” breaks all these obviousnesses and shows that philosophy begins precisely where everyday life thinks no question remains.
The enduring importance of “Being and Time” lies in this. This book is not merely a text in the history of philosophy, but an exercise in questioning again. Heidegger does not give simple answers; he transforms the horizon of questioning. After him, one can no longer understand man merely as a knowing subject, the world merely as a collection of objects, truth merely as correspondence, time merely as a sequence of nows, death merely as a final event, and history merely as a past that has passed. Even those who disagree with Heidegger must take a position in the face of the questions he opened. This is the mark of a truly influential philosopher: not that he convinces everyone, but that he changes the field of questioning so that a return to the past becomes impossible.
Thus, “Being and Time” is a work that is grand, incomplete, difficult, dangerous, and still alive. Grand, because it revived the question of Being with unprecedented power. Incomplete, because it did not fully reach its final promise, and this incompleteness opened the way for the later thinking. Difficult, because its language and concepts move at the boundary of moving beyond the metaphysical tradition. Dangerous, because some of its concepts, if read uncritically, can approach decisionism, ambiguity, or the language of historical fate. And alive, because it can still pull us out of the level of habit, information, haste, everydayness, and obviousness, and return us to questions that constitute the foundation of our life and thinking.
In final summary, one can say that “Being and Time” is a book about the truth that man is a being whose Being is an issue for him. He is in the world, with others, in history, toward death, in language, in truth and untruth, and in the temporality of care. But all these analyses serve a larger question: how is Being understood for us, and why has this understanding been forgotten in the history of philosophy? Heidegger does not give a final and closed answer to this question, but perhaps the importance of philosophy is not always in the final answer. Sometimes philosophy begins when the question is revived. “Being and Time” is such a book: a book that pulled the question of Being from beneath the ashes of obviousness and showed that thinking, prior to all else, is the ability to remain before a question that has not yet ended.
