René Descartes

René Descartes (1596–1650) was a seminal French philosopher, mathematician, and scientist, often hailed as the father of modern Western philosophy. He is best known for his philosophical statement "Cogito, ergo sum" ("I think, therefore I am") and his influential work "Meditations on First Philosophy," which continues to be a core text in university philosophy departments. Descartes also made significant contributions to mathematics, particularly in developing Cartesian coordinate geometry, which laid the groundwork for modern calculus. His method of doubt and emphasis on rationalism profoundly influenced the Enlightenment and subsequent philosophical thought. Descartes' legacy endures as a pivotal figure in the history of thought.
