Heidegger’s account of death plays a crucial role in the argument of Being and Time. There is, however, no broad consensus on how best to understand this account. An adequate interpretation of Heideggerian death should, first, explain how Heidegger distinguishes death from other phenomena such as “demise,” “perishing,” and “dying.” An adequate interpretation should also explain how relating to death in the right way transforms our existence – individualizing us and enabling an authentic form of being-in-the-world. In this chapter, I critique the “existential death interpretation” of Heideggerian death, and offer an alternative account – a modal interpretation. According to the modal interpretation, the death-demise distinction should be understood as the distinction between a possibility and an event that actualizes that possibility. The import of death is found in the way death modalizes all our other possibilities.
