René Descartes

René Descartes was born on March 31, 1596, in La Haye en Touraine, France. Educated at the Jesuit college of La Flèche, he later studied law at Poitiers before traveling widely across Europe. Settling in the Netherlands, he produced his most influential works, including "Discourse on the Method" (1637), "Meditations on First Philosophy" (1641), and "Principles of Philosophy" (1644). Descartes is celebrated for his radical method of systematic doubt, which led to his foundational principle "I think, therefore I am" (Cogito, ergo sum). He also made significant contributions to mathematics, particularly in developing Cartesian coordinates. His dualistic separation of mind and body profoundly shaped subsequent Western philosophy. Descartes died of pneumonia on February 11, 1650, in Stockholm, Sweden, while serving as a tutor to Queen Christina. His legacy endures as a pivotal figure in the transition from medieval scholasticism to modern thought.
