Volumes I and II provide a completely new translation of the philosophical works of Descartes, based on the best available Latin and French texts. Volume III contains 207 of Descartes' letters, over half of which have not been translated into English before. It incorporates, in its entirety, Anthony Kenny's celebrated translation of selected philosophical letters, first published in 1970. In conjunction with Volumes I and II it is designed to meet the widespread demand for a comprehensive, accurate and authoritative edition of Descartes' philosophical writings in clear and readable modern English.
Descartes' The World offers the most comprehensive vision of the nature of the world since Aristotle, and is crucial for an understanding of his later writings, in particular the Meditations and Principles of Philosophy. Above all, it provides an insight into how Descartes conceived of natural philosophy before he started to reformulate his doctrines in terms of a sceptically driven epistemology. Of its two parts, the Treatise on Light introduced the first comprehensive, quantitative version of a mechanistic natural philosophy, supplying a theory of matter, a physical optics, and a cosmology. The Treatise on Man provided the first comprehensive mechanist physiology. This volume also includes translations of material important for an understanding of the work: related sections from the Dioptrics and the Meteors, and an English translation of the complete text of The Description of the Human Body.
