I hold a chair for Classical German Philosophy at Humboldt-University. My main area of specialization is Kant’s philosophy and contemporary philosophy of language and metaphysics, but I also have an increasing interest in Post-Kantian thinkers such as Fichte and Hegel. My project in the KFG will focus on Kant's concept of a cognitive faculty and its epistemological implications. Kant argues that, within the framework of his transcendental idealism, the particular constitution of our own cognitive faculties grounds certain necessary and a priori recognizable structural properties of the world we experience. At the same time, he argues that it follows from the fact that our cognitive faculties bring their own form with them that we cannot use them to recognize things as they are in themselves, but rather only the potential of these things to appear to us in a certain way. I want to reconstruct in detail the epistemological and ontological consequences of this interdependence of the potentialities of recognizing subjects and recognized objects.
