 Perhaps the most influential metaphysical but non-phenomenalist interpretation of Kant’s idealism has been Langton (1998). Langton begins by pointing out that Kant thinks we are genuinely missing out on something in not knowing things in themselves, and this sense of “epistemic loss” is incompatible with Allison’s reading. As we saw in the previous section, “Allisonian humility” is apparently compatible with it being impossible that there are non-spatiotemporal objects and our forms of intuition being the only possible such forms. This loses Kant’s sense that we are genuinely cognitively deprived, that there is something about the world of which we are irremediably ignorant (Allison responds to Langton’s criticism in 2004: 9–11).
