O indivíduo autêntico atende ao chamado da consciência que o convoca a ser o que ele já é: abertura (finita) temporal. Resolvendo aceitar sua mortalidade, o indivíduo para a auto-objetificação egoísta que o impediu de ser aberto a suas possibilidades. Heidegger mais tarde minimizou os sobretons voluntariosos presentes nesta concepção de autenticidade.
Heidegger’s account of authenticity as anticipatory resoluteness is explored in Chapter Three. The authentic individual heeds the call of conscience when it summons him to be what he already is: temporal (finite) openness. By resolving to accept his mortality, the individual stops the egoistical self-objectification which had prevented him from being open for his possibilities. Heidegger later minimized the voluntaristic overtones present in this conception of authenticity. To fill out the abstract account of authenticity in Being and Time and to demonstrate how much it resembles traditional descriptions of authenticity, I conclude with three examples of the idea of authentic Being-towards-death: Plato’s characterization of Socrates; the universal myth of the hero; and Nietzsche’s conception of the Overman.
