Jean-Luc Marion is one of the most prominent young philosophers working today and one of the best contemporary Descartes scholars.Cartesian Questions, his fifth book on Descartes, is a collection of seven essays on Descartes' method and its relation to his metaphysics. Marion reads the philosopher'sDiscourse on Methodin light of hisMeditations, examining how Descartes' metaphysics changed from one book to the other and pursuing such questions as the status of the ontological argument before and after Descartes. The essays touch on the major themes of Marion's career, including the connection between metaphysics and method, the concept of God, and the constitution of the thinking subject. In their range, the essays are an excellent introduction to Marion's thought as well as a subtle and complex interpretation of Descartes. The collection is a crucial work not only for scholars of Descartes but also for anyone interested in the state of contemporary French philosophy."Besides the impact of their content, the clarity and reach of these essays force one to consider foundational questions concerning philosophy and its history."—Richard Watson,Journal of the History of Philosophy
