This concise volume is at once an excellent introduction to Kant\'s Critique of Pure Reason and an original analysis of Kant\'s ideas. Intended to be read in conjunction with Kant\'s text, Ewing\'s commentary systematically examines the Critique chapter by chapter. It offers valuable guidance to new students of Kant and thought-provoking discussion to advanced scholars. A. C. Ewing (1899-1973) was a member of the Faculty of Moral Science at Cambridge University and a Fellow of the British Academy. He taught at several universities in the United States including Princeton University and Northwestern University. His many books include and The Fundamental Questions of Philosophy and The Definition of Good.
