Action as a fundamental phenomenon of human existence

A rereading of Heidegger’s Being and time

Abstract

The essay puts forward the thesis that in the Heidegger of Being and Time, action would be the fundamental phenomenon of human existence or, for that matter, of Dasein. The argument runs through much of the existential analytics of Dasein, dwelling in greater detail, first, on the relation between facticity and action, and, second, on the observable determination between factual life or action and the structure of Sorge. It is evident that only in the power-being-own can the human being show a more authentic and resolute acting. In any case, the facticity of Dasein is not that it only gives glimpses of existence in the ontological determination of property. In the fall there is also an action. If this were not the case, it could not be argued in favor of this as the fundamental phenomenon of human existence. In the end, one could speak of a countermovement that is not given in a direct way from the factual world understood in the occupation, but that seems to require a leap from the natural attitude to the thematization of what goes unnoticed.
