Abstract

Two of Heidegger’s most fundamental distinctions, authenticity and inauthenticity, the existential and the existentiell, are motivated by Aristotle’s δύναμισ/ένέργεια distinction. Even the basic concept of truth must be understood in terms of δύναμισj and ένέργεια. Moreover, Heidegger’s existential imperative only becomes fully comprehensible within the Aristotelian context, revealing the intrinsic interrelation of Heidegger’s two distinctions with one another.
