Critique of Pure Reason

This course does not retell the four parts in order. It takes the book apart as a device: from 'judgements of this kind do hold' it reasons back to their conditions of possibility, then seals every conclusion inside those conditions. Each step is either a premise Kant chose, something that follows from his own definitions, or a textual claim refutable by the original; and the course says where this reading gives a confident and wrong answer. The A edition (1781) and the B edition (1787) differ widely, so wherever a reading turns on wording, both are checked. The last chapter audits the first six. It is an independent re-explanation based on a public-domain translation; most examples are our own and quotations name their section.
