Death understood as a possibility in this existential sense, then – that is, as something into which I project – cannot be the event at the end of my life, but must instead be a dimension of existence accessible to me, something immanent in the phenomenal structure of my being-in-the-world. How is my own death manifest and accessible to me while I am still alive? Not in my being-at-an-end ( Zu-Ende-sein ), Heidegger says, but in my being toward the end ( Sein zum Ende ). Indeed, Heidegger says, “Death is Dasein’s ownmost ( eigenste ) possibility” (SZ 263).
