René Descartes

Abstract

René Descartes (1596–1650) was born at La Haye, near Tours in France. He entered the Jesuit School at La Flèche in 1606, where he studied Latin and Greek and the classical authors, and acquired respect for the certainty of mathematics and distaste for the theories of Aristotle as developed by medieval commentators. In 1616, he took a degree in law at the University of Poitiers. There followed a period during which he travelled, for some of the time as a gentleman-officer in the armies of Maurice of Nassau, Prince of Orange, and Maximilian, Duke of Bavaria. In 1625 he returned to Paris and renewed his acquaintance with Father Marin Mersenne, who was later instrumental in making his views known to many of the famous intellectuals in Europe. From 1628 to 1649 he lived in Holland and worked out in detail the scientific, philosophical and mathematical ideas that had engaged him during his travels. His main philosophical works are Rules for the Direction of the Mind, written in 1629–30 but not published until 1684, Discourse on Method, 1637, Meditations, 1641, Principles of Philosophy, 1644, and The Passions of the Soul, 1649. In 1649, Descartes accepted an invitation to visit the Queen of Sweden and instruct her in philosophy. He succumbed to the rigorous climate, and died in February 1650.
