Overview
René Descartes (1596–1650) was a French mathematician and philosopher who helped launch early modern rationalism. Educated by Jesuits, he traveled as a soldier and settled for long periods in the Dutch Republic. Discourse on Method and the Meditations sought certain foundations for science after skeptical crisis. He corresponded widely and briefly tutored Queen Christina of Sweden, where he died. Handbook dates: 1596–1650. Analytic geometry and mechanistic physics accompany his metaphysical dualism.
Main ideas
Methodic doubt strips away uncertain beliefs until the cogito—thinking existence—stands firm. Clear and distinct perception, guaranteed by a non-deceiving God, rebuilds knowledge of mind, God, and material nature. Mind is thinking substance; body is extended substance—raising the interaction problem. Mathematical physics explains nature by figure and motion rather than substantial forms. Error arises from will outrunning understanding. The passions are explained physiologically yet ethically trainable for a contented life.

Legacy
Descartes became the emblematic modern subject and a permanent sparring partner for empiricists, Kantians, and phenomenologists. His mathematics reshaped science; his dualism frames mind–body debates still. Classroom philosophy often begins with the Meditations’ skeptical ascent.
