Who was Heidegger?

Martin Heidegger (1889-1976) stands as one of the most influential and controversial philosophers of the 20th century. His groundbreaking work, particularly his magnum opus Being and Time (1927), revolutionized the field of ontology and laid the foundations for existentialism, hermeneutics, and postmodern thought. Heidegger’s relentless pursuit of the meaning of Being, his critique of Western metaphysics, and his analysis of human existence as Dasein (“being-there”) continue to shape philosophical discourse and inspire thinkers across disciplines.

Yet Heidegger’s legacy is also marred by his troubling political affiliations, most notoriously his involvement with National Socialism during his tenure as rector of the University of Freiburg in the 1930s. His failure to fully acknowledge or repudiate his Nazi ties after World War II has cast a long shadow over his life and work, raising profound questions about the relationship between philosophy and politics, the ethics of intellectual engagement, and the possibility of separating a thinker’s ideas from their personal history.

Despite these controversies, Heidegger’s thought has had a profound impact on the theory and practice of psychotherapy, particularly in the existential-humanistic and depth psychological traditions. His phenomenological exploration of human being-in-the-world, his understanding of authenticity and inauthenticity, his notion of thrownness and existential anxiety, and his reflections on language, truth, and the nature of thinking have all found resonance in the therapeutic endeavor to understand and alleviate psychological suffering.

This essay aims to critically examine Heidegger’s key ideas and their relevance for psychotherapy and depth psychology, while also grappling with the ethical implications of his political entanglements. By engaging both the light and shadow of Heidegger’s legacy, we may deepen our understanding of the human condition and the challenges of living an authentic life in an uncertain world.

Being and Time: The Question of Being

2.1. Dasein and Being-in-the-World

At the heart of Heidegger’s philosophy is the question of Being (Sein) – what it means for something to be, to exist, to manifest as a presence. For Heidegger, this question had been neglected or obscured throughout the history of Western thought, which had tended to focus on particular beings (entities) rather than the underlying meaning and ground of Being itself.

To approach this question, Heidegger turns to an analysis of human existence, which he calls Dasein (“being-there”). Dasein is not just another entity in the world, but the being for whom Being is an issue, the being who has an understanding (however vague) of its own existence and the existence of other beings. Dasein is characterized by its openness to the world, its ability to encounter and engage with other beings, and its capacity for self-reflection and self-interpretation.

Heidegger emphasizes that Dasein is always already “in-the-world” – not a detached subject confronting an external object, but a being fundamentally immersed and involved in a meaningful context of relationships, projects, and possibilities. The world is not a mere container or a collection of things, but the horizonal background against which beings can appear and make sense. Dasein inhabits this world through its everyday activities and concerns, its moods and attunements, and its shared cultural understandings and practices.

2.2. Authenticity and Inauthenticity

For Heidegger, Dasein’s being-in-the-world is characterized by two fundamental modes or possibilities: authenticity (Eigentlichkeit) and inauthenticity (Uneigentlichkeit). Inauthenticity is Dasein’s default mode, its absorption in the everyday world of the “they” (das Man) – the anonymous, conformist mass of average understanding and behavior. In this mode, Dasein flees from its own finitude and responsibility, taking refuge in the familiar routines and opinions of the crowd. It relates to the world and to itself in a superficial, unreflective way, governed by idle talk, curiosity, and ambiguity.

Authenticity, in contrast, involves Dasein’s resolute facing up to its own existence as a finite, mortal being thrown into a world not of its own making. It means taking responsibility for one’s own possibilities, embracing one’s facticity and historicity, and projecting oneself into an uncertain future. Authenticity is not a permanent state or achievement, but a moment of clarity and decision in which Dasein breaks free from the “they” and takes ownership of its being.

Heidegger stresses that authenticity is not a matter of heroic individualism or self-aggrandizement, but a way of being attuned to the call of conscience (Gewissen) – the silent voice of Dasein’s own being that summons it to its authentic possibilities. This call is experienced as a profound uncanniness or not-at-homeness (Unheimlichkeit), a disturbance of Dasein’s everyday familiarity that reveals the groundlessness and finitude of its existence.

2.3. Thrownness, Anxiety, and Being-toward-Death

Heidegger’s notions of thrownness (Geworfenheit) and anxiety (Angst) are crucial for understanding Dasein’s existential predicament. Thrownness refers to the fact that Dasein always finds itself already situated in a world, in a particular historical, cultural, and personal context that it did not choose or create. Dasein is “thrown” into existence, into a set of possibilities and limitations that it must take up and make its own.

Anxiety, for Heidegger, is not a mere psychological state or a response to a specific threat, but a fundamental attunement that reveals Dasein’s being-in-the-world as a whole. In anxiety, the familiar meanings and structures of the everyday world collapse, and Dasein is confronted with the uncanniness and contingency of its own existence. Anxiety discloses Dasein’s freedom and responsibility, its being-possible, and its being-toward-death (Sein-zum-Tode).

Being-toward-death is Heidegger’s term for Dasein’s inherent finitude, its inescapable mortality that shapes its entire existence. Death is not just an event that happens at the end of life, but a constant possibility that haunts Dasein from the very beginning. Authentic being-toward-death means facing this possibility with clear-sighted resoluteness, accepting one’s own finitude and living in light of it. It means embracing the fact that one’s possibilities are always limited and that one’s existence is ultimately groundless and unsecured.

Language, Truth, and the History of Being 3.1. The House of Being

In his later work, Heidegger increasingly turns to the question of language and its relationship to Being. For Heidegger, language is not merely a tool for communication or a system of signs, but the very “house of Being” – the medium in which Being reveals itself and comes to presence. Language is the way in which the world is disclosed and made intelligible, the way in which beings are gathered together and brought into the open.

Heidegger’s reflections on language lead him to a critique of the instrumental and calculative thinking that dominates modern technology and science. He argues that this kind of thinking reduces beings to mere objects or resources, obscuring their inherent meaning and mystery. In contrast, Heidegger calls for a more meditative and poetic thinking that lets beings be, that attends to their unconcealment and preserves their strangeness and wonder.

3.2. Aletheia and the Clearing

Heidegger’s understanding of truth departs from the traditional notion of correspondence or correctness. For Heidegger, truth (aletheia) is not a property of propositions or a relation between statements and facts, but the very unconcealment or disclosure of beings in their Being. Truth is the opening up of a clearing (Lichtung) in which beings can show themselves as they are, the setting-into-work of the strife between concealment and unconcealment.

This conception of truth is closely tied to Heidegger’s interpretation of the history of Being – the way in which Being has been understood and articulated in different epochs of Western thought. Heidegger argues that the history of Being is a history of forgetting, a gradual obscuring of the question of Being and a progressive domination of beings by human will and representation. The task of thinking, for Heidegger, is to step back from this metaphysical tradition and to recover a more original and authentic understanding of Being.

Implications for Psychotherapy and Depth Psychology

4.1. Existential-Humanistic Psychology

Heidegger’s thought has had a profound influence on the development of existential-humanistic psychology, particularly through the work of scholars like Medard Boss, Rollo May, and Irvin Yalom. Heidegger’s phenomenological approach, his emphasis on being-in-the-world and the existential structures of human existence, has provided a rich philosophical foundation for a therapeutic practice that aims to help individuals confront and come to terms with the basic conditions of their lives.

Heidegger’s notions of authenticity and inauthenticity, thrownness and anxiety, and being-toward-death have been particularly influential in shaping the existential-humanistic understanding of psychological health and pathology. From this perspective, psychological suffering arises not merely from intrapsychic conflicts or behavioral maladaptations, but from a fundamental estrangement from one’s own being and possibilities. Authenticity becomes a key therapeutic goal – not as a state of perfect self-actualization, but as a way of being that faces up to the realities of existence and takes responsibility for one’s own life.

Heidegger’s critique of the “they” and his emphasis on the call of conscience also resonates with the existential-humanistic focus on individual autonomy and self-determination. The therapeutic process is seen as a way of helping individuals break free from the conformist pressures of society and discover their own authentic voice and path. At the same time, Heidegger’s understanding of being-in-the-world challenges the notion of the isolated, self-contained individual, highlighting the fundamental interconnectedness and co-constitution of self and world.

4.2. Depth Psychology and Hermeneutics

Heidegger’s thought has also had a significant impact on depth psychology, particularly through his engagement with the work of Sigmund Freud and Carl Jung. While Heidegger was critical of Freud’s psychoanalytic theory, seeing it as a form of technological and reductive thinking, he acknowledged the importance of Freud’s discovery of the unconscious and the way in which it challenges the traditional notion of the autonomous, rational subject.

Heidegger’s own understanding of the unconscious, however, differs from Freud’s in important ways. For Heidegger, the unconscious is not a seething cauldron of repressed instincts and childhood traumas, but the very ground and mystery of our being-in-the-world. It is the unthought and unsaid that pervades our existence, the concealed depths that can never be fully brought to light. Heidegger’s notion of the uncanny (Unheimliche) – the strange and unsettling that lurks beneath the familiar – has been particularly influential in depth psychological explorations of the shadow and the numinous.

Heidegger’s hermeneutic philosophy, with its emphasis on interpretation and the circular structure of understanding, has also had a significant impact on depth psychology. Heidegger challenges the notion of a neutral, objective observer who can uncover the hidden meanings of the psyche, arguing that all understanding is always already shaped by the interpreter’s own historical and cultural horizons. This insight has led to a more dialogical and intersubjective approach to therapy, one that acknowledges the co-construction of meaning between therapist and client.

The Shadow of Heidegger: Politics and Ethics

5.1. Heidegger and National Socialism

No consideration of Heidegger’s legacy can ignore his troubling involvement with National Socialism during the 1930s. In 1933, Heidegger joined the Nazi Party and was appointed rector of the University of Freiburg, where he delivered a notorious inaugural address that seemed to align his philosophy with Nazi ideology. While he resigned the rectorship after less than a year, Heidegger remained a member of the Nazi Party until the end of World War II and never publicly apologized for or fully accounted for his political activities during this period.

Heidegger’s involvement with Nazism raises profound questions about the relationship between his philosophy and his politics. Some scholars have argued that there are deep affinities between Heidegger’s critique of Western metaphysics, his emphasis on the historicity of Being, and his valorization of the German Volk and the Nazi revolution. Others have seen Heidegger’s Nazism as a personal failing that is separable from his philosophical insights, or as a misguided attempt to realize his ideas in a concrete political movement.

5.2. The Ethics of Authenticity

Heidegger’s notion of authenticity has also been criticized from an ethical perspective. Some have argued that Heidegger’s emphasis on resoluteness and self-determination, his valorization of the heroic individual who faces up to the groundlessness of existence, can lead to a kind of moral relativism or decisionism that is indifferent to the suffering of others. Heidegger’s own failure to confront the atrocities of the Nazi regime, his postwar silence about the Holocaust, can be seen as a troubling embodiment of this tendency.

At the same time, others have argued that Heidegger’s notion of authenticity, properly understood, is not a matter of arbitrary self-assertion or a rejection of moral norms, but a call to take responsibility for one’s own existence in light of the demands of the situation. Authenticity involves a heightened sensitivity to the claim of the other, a recognition of the shared finitude and vulnerability that binds us together. From this perspective, Heidegger’s thought can be seen as a powerful resource for an ethics of alterity and care, one that challenges the egoism and instrumentalism of modern individualism.

Heidegger’s Legacy

Martin Heidegger’s thought remains a source of both insight and controversy, a profound exploration of the meaning of Being that is haunted by the specter of its political entanglements. For psychotherapy and depth psychology, Heidegger’s work offers a rich and challenging set of ideas that can deepen our understanding of the human condition and the nature of the therapeutic encounter. His phenomenological approach, his emphasis on being-in-the-world and the existential structures of human existence, his reflections on language, truth, and the history of Being, all provide valuable resources for a more situated, embodied, and relational understanding of psychological life.

His critique of the Cartesian subject, the notion of an isolated, self-contained ego that can be analyzed and manipulated from an external standpoint, calls into question the hierarchical and objectifying tendencies of much therapeutic practice. Heidegger’s emphasis on the co-constitution of self and world, the way in which our very being is always already shaped by the social and material contexts in which we are embedded, suggests the need for a more dialogical and relational approach to therapy, one that recognizes the therapist as an active participant in the co-creation of meaning and possibility.

Heidegger’s reflections on language and truth also have important implications for the therapeutic process. His understanding of language as the house of Being, the medium in which our world is disclosed and made intelligible, suggests that therapy is not simply a matter of uncovering pre-existing truths or applying predetermined techniques, but a creative and poetic process of articulating new possibilities of meaning and experience. The therapist’s role is not to impose a fixed interpretation or solution, but to help the client to dwell in the open space of language, to find new and more authentic ways of expressing and understanding their being-in-the-world.

This poetic dimension of therapy is closely tied to Heidegger’s notion of aletheia, the unconcealment or disclosure of beings in their Being. For Heidegger, truth is not a static correspondence between propositions and facts, but a dynamic process of revealing and concealing, a strife between light and shadow. The therapeutic encounter, from this perspective, is not a search for a final, definitive truth, but a ongoing journey of exploration and discovery, a continual unfolding of new horizons of meaning and possibility.

Finally, Heidegger’s thought challenges us to consider the ethical and political dimensions of psychotherapy in a new light. His own troubled history with National Socialism serves as a stark reminder of the ways in which even the most profound philosophical insights can be distorted and misused in the service of oppressive and destructive ends. It calls upon us to be vigilant about the potential dangers of any totalizing or absolutist vision, whether in the realm of theory or practice, and to cultivate a critical and self-reflexive stance towards our own assumptions and commitments.

At the same time, Heidegger’s understanding of authenticity and care, his emphasis on our responsibility to the historical moment and the claim of the other, suggests a new basis for an engaged and transformative therapeutic practice. It calls upon therapists to be attuned to the larger social and political contexts in which their clients are situated, to recognize the ways in which individual suffering is often rooted in systemic oppression and injustice. And it challenges us to envision a form of therapy that is not merely a means of personal adjustment or coping, but a catalyst for social and cultural change, a way of empowering individuals and communities to create more authentic and compassionate forms of life.

As we look to the future of psychotherapy and depth psychology, Heidegger’s legacy offers both inspiration and caution, insight and provocation. It reminds us of the enduring power and relevance of the existential and ontological questions that animate the therapeutic endeavor, even as it challenges us to rethink some of our most basic assumptions and frameworks. It calls us to a more poetic and dialogical understanding of the therapeutic process, one that is attuned to the language and truth of human existence. And it invites us to envision a more ethically and politically engaged form of therapy, one that recognizes the deep interconnectedness of personal and collective transformation.

In the end, perhaps the most enduring legacy of Heidegger and the tradition of depth psychology is the invitation to a life of questioning and wonder, a life that is open to the mystery and the beauty of the world in all its terror and splendor. As therapists and as human beings, we are called to embrace this invitation with all the passion and compassion we can muster, to join in the great adventure of the soul as it seeks to find its way home. May we have the strength and the grace to answer this call, to dwell poetically and think meditatively in the midst of the storms and the silences of our age.
