Heidegger on death as a deficient mode

Heidegger conceives Dasein’s death as a peculiar type of negation, i.e., a negation that is not simple disappearance, and so is, in some sense, survived by Dasein. This paper argues that Heidegger’s technical terminology for this type of negation is the “deficient mode.” The ontological structure of the deficient mode is characterized by Heidegger as a mode of the “nur noch,” which is a way of just being. And to just be, in the sense that deficient modes just are, is grounded in the unique identity conditions characteristic of a being that can exist in deficient modes—its identity is an unnecessary necessity, and so its loss is a possible impossibility. Hence, the connection with Dasein’s death, which Heidegger defines as “the possibility of the absolute impossibility of Dasein.” Death is Dasein in a deficient mode. This interpretation of Heideggerian death is then used to address the debated issue concerning Heidegger’s distinction between death and demise.
