Key Texts are facsimile paperback editions of books which have not been available for many years. This series gives particular emphasis to less popularized works of major thinkers in the history of ideas. 'Kenny's Descartes is a notably good and an important book. He says it is "designed to help undergraduate and graduate students in understanding Descartes' philosphy". The book concentrates on Descartes' epistemology, metaphysics, and philosophy of mind: but the penultimate chapter, on Matter and Motion, contains a succient account of Descartes' mechanism and a critique of the a priori side of his natural philosophy.'
