ABSTRACT
Before we can analyze the finitude of Dasein we must get clearer about the nature of this entity. For the purposes of my discussion of time and death, I do not need to go into all the details of the first division of Part One of Being and Time, the early work that provided an 'existential analytic· of Dascin 's being and set up Heideggcr's lifelong task in philosophy. But we do need an account of the general project and structure of the published work, which I provide in Section 1.1. Sections 1.2 and 1.3 examine Dasein's selthood and the difference between authenticity and inauthenticity. The fourth section examines the issue of the 'tum' or 'reversal' in Heidegger 's thought and the relevance of his later work for understanding what is at issue in Being and Time.
