Martin Heidegger's Kant-interpretation is important and deeply intertwined with the existential phenomenology of Being and Time that it is impossible to understand one without the other. For an analysis of the positive content of Heidegger's Kant-interpretation, the reflections on the supposed violence of Heidegger's appropriation of Kant imply the following. First, one gets a more complete idea of the significance of Heidegger's recasting of Kantian themes by understanding how Heidegger's phenomenological interpretation of Kant at the same time undermines neo-Kantian epistemological readings. Second, much of the positive content of Heidegger's work on Kant shows up as Kant-inspired arguments in Being and Time; in particular Heidegger's analysis of originary temporality can only be understood in light of his analysis of Kant's transcendental deduction. Finally, this substantial overlap is bounded by a fundamental criticism that Heidegger levels against Kant's notion of the self.
