Abstract
This article aims to read and clarify the Heideggerian interpretation of the Aristotelian chapter Metaphysics Θ 10, as it is mainly expressed in the lecture course of 1930, titled The essence of human freedom. An introduction to philosophy. The purpose of such reading is to show why Heidegger recognizes in the true being, in terms not only Aristotelian but Greek in general, the privilege of “authentic being”. Only from these reasons will it be possible to understand how the Greek question of being, in the classical formulation τί τὸ ὄν, is presented as the guiding question of philosophy and why Heidegger’s thought seeks a more original development of the same question in “fundamental question”, which ultimately regards being and time in their mutual belonging.
