The central novel claim of the book is that in the B-Deduction Kant provides a proof of the derivability of each of the twelve categories from the principle of apperception. This goes against the current view that the Transcendental Deduction is not a proof in the strict philosophical sense and the standard reading that the Deduction only gives an account of the global applicability of the categories.
