![]() He writes, ‘If I ask about the magnitude of the world with respect to space and time, … it is just as impossible to assert that it is infinite as that it is finite. This anomaly is compounded by the fact that what Kant thinks he can pronounce about the size and age of the physical universe, and in particular what he thinks he can pronounce about whether the physical universe is infinite or finite in each of these respects, is that it is, in each of these respects, neither-the point being that, despite his hostility to logical positivism, he subscribes to a sort of verificationism that makes both these possibilities variations on the same problematic theme. Surely not: surely we must once again defer to physicists. There is a similar anomaly in §52, where Kant thinks he can pronounce on the size and age of the physical universe on purely a priori grounds. ![]() Indeed I cannot myself see how he falls short of simply asserting something that we know from physicists to be false, namely that physical space is Euclidean. ![]()
