Descartes is perhaps most closely associated with the title, “the Father of Modern Philosophy.” Generations of students have been introduced to the study of philosophy through a consideration of hisMeditations on First Philosophy. His contributions to natural science is shown by the fact that his physics, as promulgated by the Cartesians, played a central role in the debates after his death over Isaac Newton’s theory of gravitation. Descartes also made major contributions to the field of analytic geometry; we still speak today of “Cartesian coordinates” and the “Cartesian product.”This second edition ofHistorical Dictionary ofDescartes and Cartesian Philosophy covers the history through a chronology, an introductory essay, and an extensive bibliography. The dictionary section has over 300 cross-referenced entries on various concepts in Descartes’ philosophy, science, and mathematics, as well as biographical entries about the intellectual setting for Descartes’ philosophy and its reception, both with Cartesians and anti-Cartesians. This book is an excellent access point for students, researchers, and anyone wanting to know more about Descartes.
