《Prolegomena to Any Future Metaphysics》 - 免费有声读物

Kant's Prolegomena, although a small book, is indubitably the most important of his writings. It furnishes us with a key to his main work, The Critique of Pure Reason; in fact, it is an extract containing all the salient ideas of Kant's system. It approaches the subject in the simplest and most direct way, and is therefore best adapted as an introduction into his philosophy. - Summary by Open Court Publishing Company
