being-in-the-world. understanding the phenomenon of death involves grasping the Being as a whole. If you is understood existentially as a possibility, then it becomes clear that Dasein’s authentic Being in its totality is ‘Being-towards-death’. Through facing death, Dasein understands what it means to be. This reflective process is the crux of Heidegger’s analysis of death. In order to clarify his views on the existential conception of death, Heidegger distinguishes between two basic forms of Being: authentic and inauthentic Being.
