Martin Heidegger, another influential existentialist philosopher, explored the concept of being toward death in his seminal work, Being and Time.

Heidegger posited that an authentic existence requires an active engagement with the inevitability of death.

He introduced the idea of Dasein, which refers to the human condition of being aware of and concerned with one's own existence.

Heidegger argued that individuals often fall into the state of inauthenticity, where they distract themselves from the reality of death through everyday routines and societal conventions.

To live authentically, one must confront the anxiety of death and embrace it as a fundamental aspect of existence.

This confrontation can lead to a deeper understanding of one's own being and more meaningful engagement with life.
