Zimmerman (1982:xxii-xxiii) – A inautenticidade

Chapter Two is an analysis of Being and Time’s claim that by concealing his finitude, the inauthentic individual is able to understand himself as an eternal thing (ego). The inauthentic individual seeks security by attempting to manipulate the world. Although (xxii) the egoist thinks that he is fully individuated, the fact is that his goals, opinions, and desires are largely determined by prevailing social customs and expectations. The egoism of inauthenticity corresponds to the Christian idea of sinfulness as depicted by Rudolf Bultmann, with whom Heidegger worked closely in the 1920s. Heidegger and Bultmann agreed that the opposite of inauthenticity and sinfulness is openness; they disagreed on how such openness can be gained. As a young man, Heidegger stressed the need for courage and will; Bultmann stressed the need for grace.
