As we have seen, Heidegger holds fast to Kant's doctrine that all knowledge is "originally and finally" intuition. Our human intuition is essentially finite, and thus requires the reception of the being through our sensibility. This finitude also entails the need for a priori knowledge of the Being of beings in order to know those beings given in intuition. The problem of how this a priori knowledge actually relates to those beings received in sensation is the problem of transcendence, and Heidegger has correctly claimed that this is the central problem of the Critique of Pure Reason.¹
