Kant's a Priori Is the Way to Think Through All Experience

Land says madernity is indicative of this cantian approach that tries to remove itself from all experience. So he uses the principles of the a priori to think about experience itself and asks, how is it possible that we are able to have experience at all? What is it within us that we can only think about a priori that makes experience possible? It's through that that we land kind of sketches what kant is doing, which is pretty much positioning the a Priori as the way to think through all experience.
