Abstract

This chapter presents the text of the Lectures on Ethics, which was compiled by Paul Menzer from manuscript notes of Kant's annual lectures. In the Lectures, Kant formulates a clear conception of the nature of ‘practical philosophy’ as a science which is concerned with the purely rational a priori laws governing the conduct of beings possessed of a free will. In view of what critics have sometimes said about the absence of a concern for personal happiness in Kant's ethics, one should note his final unequivocal declaration that ‘God's will is that we should make ourselves happy' and that this is the true morality’. A fairly large section of the Lectures on Ethics is devoted to the doctrine of religion, and as well as being independently interesting as an account of Kant's attitude to religion, it helps to make more explicit the general metaphysical background which forms the context for his developing ethical theory.
