Heidegger's Philosophy of Death

Aug 4, 2025

Overview

This lecture explores Martin Heidegger's philosophy of death, primarily from his work "Being and Time," and discusses how our understanding of mortality shapes life, ending with a critique from Jean-Paul Sartre.

Heidegger's Central Philosophical Concerns

  • Heidegger's main question in "Being and Time" is the meaning of being, not just individual beings.
  • He uses a phenomenological approach (based on experience) to examine human existence (Dasein).
  • Dasein is not just a biological human, but the entity that asks about being and finds meaning in the world.
  • Dasein’s state is characterized by "care," meaning being ahead-of-itself, already-in-the-world, and being alongside others and things.

Dasein’s Structure and Wholeness

  • Dasein is “thrown” into the world (thrownness), not choosing its circumstances.
  • Dasein always exists with others and follows societal norms (fallenness).
  • Dasein constantly projects itself into future possibilities (projection).
  • Wholeness of Dasein can't be found in its current state but only at its end—its death.

Heidegger's Concept of Death

  • Death is uniquely "mine"; only I can face my own death.
  • Death is not an empirical event but an existential phenomenon: the end of being-in-the-world.
  • Heidegger differentiates between demise (biological end), perishing (end for all living things), and existential death (end of Dasein's potential).
  • Dasein is always "being towards death," a possibility it cannot avoid.
  • Death is certain, indefinite in its timing, non-relational, and not transferable to others.

Everydayness and Inauthenticity

  • In everyday life, people inauthentically relate to death by treating it as distant or statistical ("the they" or societal norms).
  • The "they" trivialize death, prescribing tranquility or fear instead of genuine anxiety.

Authentic Being-Towards-Death

  • Authenticity is acknowledging death as one's own most, non-relational, inescapable, certain, and indefinite possibility.
  • Authentic being-towards-death involves anticipating death and living with existential anxiety, rather than fleeing from it.
  • Authenticity leads to individual freedom and a fuller grasp of one's own possibilities.

Sartre's Critique and Heidegger's Response

  • Sartre argues that death is not "mine" but an annihilation of possibilities from outside.
  • He claims Heidegger internalizes death while in fact, death is an external event.
  • Heidegger responds that Sartre confuses existential death with demise; death is not an event but a way of being.

Key Terms & Definitions

  • Dasein — The human being as the entity that asks about and finds meaning in being.
  • Care — The foundational structure of Dasein, comprising thrownness, fallenness, and projection.
  • Thrownness — The condition of being placed into a world not of one’s choosing.
  • Projection — Dasein’s orientation toward future possibilities.
  • Fallenness — Adoption of social norms and expectations, resulting in inauthentic existence.
  • Being-towards-death — Dasein’s way of anticipating its end and integrating mortality into existence.
  • The They — Societal norms and the collective way of interpreting experience.
  • Authenticity — Living in full awareness and acceptance of one’s own mortality and possibilities.

Action Items / Next Steps

  • Review the characteristics of care (thrownness, fallenness, projection) as they relate to Dasein.
  • Read Heidegger’s "Being and Time," focusing on Division Two (Being-towards-death).
  • Consider the differences between Heidegger’s and Sartre’s views on death for class discussion.
