From Mataphysical Freedom to Existential Freedom

In this essay we try to show the place of freedom (free will) in Kant’s thought according to Heidegger’s interpretation; according to this interpretation, freedom is not a metaphysical and noumenal freedom for human as Subject but an existential one that makes him possible as a Dasein (being- in- world). Such a fundamental freedom is not provable and cannot be treated by any theoretical speculation, rather we encounter it in our actions and in the process of making free decisions, finding philosopher’s theoretical attempts to prove it in vain. The actuality of freedom must be searched in ourselves and in our own state of being, not in a lifeless and systematic arguments of philosopher’s; And it is Kant that discovers this point implicitly in his second Critic (The Critique of Practical reason) causing a great turn for Heidegger's thought.
