René Descartes (1596–1650) was a foundational figure in modern philosophy and mathematics who revolutionized Western thought through his method of systematic doubt and his famous dictum 'Cogito, ergo sum' (I think, therefore I am). A creative mathematician who developed algebraic geometry, a natural philosopher who advanced optics and meteorology, and a metaphysician who articulated Cartesian dualism—the doctrine that mind and body are fundamentally distinct substances—Descartes shaped the intellectual landscape of modernity by proposing a mechanistic vision of the natural world governed by universal laws while maintaining a special place for the immaterial human mind.
