Despite the well-known Kantian distinction, the relationship between theory and praxis turns out to be much richer than it might appear at first. This is not only because the definition in the Critique of Pure Reason leaves a space open for further determinations, but also because the further developments of Kant’s criticism, in particular the Third Critique, seem to converge towards the conjunction of these two poles : towards the principle of the unity of speculative and practical reason. The aim of this essay is to expose the problematic nature of the Kantian distinction by showing its partiality, in order to offer a broad perspective on a reason that, as a whole, realizes itself in the world.

Referring to Kant’s presence in Heidegger’s late ‘20s courses, this essay aims to investigate: 1. the productive and hidden consequences of these interpretations; 2. how Heidegger assumes the fundamental-question of Kant’s transcendental philosophy as a stand-point to the turn; 3. how the question of metaphysics – which Heidegger has always thought about and around which the Kehre moves – hinges on Kant. The Heideggerian reappraisal of Kantian critical-transcendental metaphysics leads to the question of foundation which reverts towards Aristotelian thought, and the recovery or abandonment of the former jointly proceeds with the recovery or the abandonment of the latter. The question about metaphysics signifies a trail sign towards Kant, following which one can try to read Heidegger in a non-dogmatic way.
