Kant and Heidegger: The Place of Truth and the Shrinking Back of the Noumena

Abstract

There is much debate on how to understand Kant’s transcendental idealism in the context of the Critique of Pure Reason. Heidegger’s Kant and the Problem of Metaphysics offers an innovative reading of Kant’s Critique of Pure Reason, but is often overlooked due to the violence it allegedly does in its interpretation. This paper offers a Heideggerian-inspired phenomenological or ontological interpretation of transcendental idealism by drawing on Heidegger’s interpretation of the Critique. First, I draw a connection between the two uses of noumena in the Critique (boundary-concepts and regulative ideas) and, in doing so, draw attention to how the noumena relies on a concept of the proper which gains its meaning from outside the system. I then bring together Kant and Heidegger on the question of the place of truth and the role of the noumena. I claim not only that the ‘noumena’ reveals a ‘shrinking back’ from the ontological (onto-ethical) release of aletheia; but also, and as a consequence, that the ‘noumena’ does not represent ‘another world,’ but rather is the grounds of the constitution of the phenomenal world itself. Thus, I argue that the noumena is the being of the phenomena, and I do so through looking at objects, faculties, and ethics in the Critique. Finally, I claim that the understanding and reason must both be receptive: even the self-given is ultimately being given.
