Abstract

Heidegger’s early period is one of the most silent in the lifetime of the great German philosopher. During that period he planned his most celebrated undertaking, Being and Time, which has influenced in manifold ways the philosophical thought of the 20th century. The lead role that Aristotle holds in the university courses and the writings of this period and more specifically his practical philosophy, which Heidegger will attempt to reform and subsume into his own philosophical system, will raise the question of the relationship between two fundamental human activities: Theory and Praxis. What is however the content that praxis will eventually take within the Heideggerian framework? What is its genuine affinity with the Aristotelian θεωρία? The examination of Heidegger’s attempt to transcend the distinction between theory and praxis and to compete with the very force of the Aristotelian position leads us to reconsider the form that this relationship takes in the human being.
