The Blackwell Guide to Descartes’ Meditations consists of twelve newly commissioned essays on one of the most influential and widely taught texts in the history of philosophy. The volume touches on all of the major themes of the Meditations, including the mind–body relation, the nature of the mind, and the existence of the material world. The volume also includes William Molyneux’s famous early translation of the Meditations. Situating the Meditations’ arguments in their philosophical and historical context, the essays in this volume constitute an ideal companion to Descartes’ masterwork.
