Heidegger on Existentiality,Constancy, and the Self

In Being and Time, Heidegger develops an account of the self in terms of his existential ontology. He contrasts his view to Cartesian and Kantian accounts, and seems to reject features that we take to be fundamental for a self, such as diachronic unity and being the subject of one's experiences. His positive account is obscured by the difficult vocabulary of authenticity and temporality. This paper traces Heidegger's argument, outlines his existential conception of the self, and shows how it fits the basic criteria for a self.
