French philosopher and mathematician who founded methodic doubt and advanced analytic geometry.

Biography

Overview

René Descartes (1596-1650) was a soldier, a mathematician, and the founder of modern philosophy. Born to French nobility and educated by Jesuits, he served in various European armies before settling in the Netherlands for its intellectual tolerance. In 1619, he experienced a vision: a unified method for all sciences grounded in mathematical certainty.

Despite initial caution due to the Church’s condemnation of Galileo, he eventually published the *Discourse on Method* (1637), featuring his famous 'I think, therefore I am': the foundational certainty that survives radical doubt. In his *Meditations* (1641), Descartes rebuilt knowledge from this core, defending the existence of God and the reliability of 'clear and distinct' ideas. His claim of a fundamental distinction between mind and body, known as Cartesian dualism, profoundly influenced Western thought, setting the stage for the Enlightenment.
