Abstract

In this paper I try to show that Heidegger develops in Being and Time an ethics of the authenticity, which doesn´t consist in the prescription of rules of action, but in a certain attitude, which the Dasein has to adopt toward his own mortality. In relation to this aim I will consider the problems of the state of Verfallenheit, the anxiety and the death as an own possibility. These themes are analyzed from the point of view of the dichotomy that Heidegger establishes between the authentic existence and the unauthentic existence
