Kant

1724 – 1804 · German Idealists · Kant and the Germans · 2 works

Everything Kant built comes out of one reversal. For two thousand years philosophers had assumed that to know the world, the mind has to copy it, to line itself up with how things really are out there. Kant asked the question backwards: what if the mind doesn't copy the world but shapes it, so that the order we find in nature is order the mind itself put there? That single flip, which he called his Copernican revolution, secures science, fences off what reason can't reach, and then, in the empty room the fence creates, makes space for a moral law every rational being gives to itself. The hardest thing in the whole subject, written by the most punctual man in Prussia.
