 Nor is it true that the uncognizability of things in themselves is trivial, on Allison’s reading. For that principle only follows from the claim that there are sensible epistemic conditions, space and time. And that, on Allison’s reconstruction, is the key insight that sets Kant apart from both his rationalist and empiricist predecessors. Thus, while Allison’s interpretation makes the argument for the non-spatiality of things in themselves relatively easy, it does not render the conclusion trivial.
