What Critique Actually Means

Reason gets into trouble just by doing its job. That is the first thing Immanuel Kant tells you in the Critique of Pure Reason, and Paul Guyer, who translated the book, starts there: with a sentence about questions we can neither answer nor put down. Then the famous claim that Kant did to metaphysics what Copernicus did to the sky. Guyer reads the metaphor more closely than Kant ever did, and finds it concealing the very thing the whole Critique exists to protect. And that line about denying knowledge to make room for faith? It does not mean what you have heard it means.
