‘Kant”s Critique of Pure Reason’ remains one of the landmark works of Western philosophy. Most philosophy students encounter it at some point in their studies but at nearly 700 pages of detailed and complex argument it is also a demanding and intimidating read. James O”Shea”s short introduction to ‘CPR’ aims to make it less so. Aimed at students coming to the book for the first time, it provides step by step analysis in clear, unambiguous prose. The conceptual problems Kant sought to resolve are outlined, and his conclusions concerning the nature of the faculty of human knowledge and possibility of metaphysics, and the arguments for those conclusions, are explored. In addition he shows how the ‘Critique’ fits into the history of modern philosophy and how transcendental idealism affected the course of philosophy. Key concepts are explained throughout and the student is provided with an excellent route map through the various parts of the text.
