Decartes

Rene Descartes was a 17th-century French philosopher and mathematician. He is considered one of the greatest philosophers in history, and his ideas continue to influence contemporary thought. Born on March 31, 1596, in La Haye, France, Descartes studied law at the University of Poitiers. However, he eventually turned to mathematics and philosophy, becoming one of the most prominent figures in the Scientific Revolution.

Descartes is best known for his philosophical method, which he set forth in his influential work, "Meditations on First Philosophy." This work introduced the concept of "I think, therefore I am" (Cogito, ergo sum), which asserts the existence of the self as a thinking being independent of external validation. He used this approach to challenge the authority of traditional knowledge, searching for certainty in a world where traditional authority was being undermined.

In addition to his philosophical contributions, Descartes also made significant contributions to mathematics. He is credited with the discovery of the method of solving systems of linear equations using determinants, as well as the introduction of Cartesian coordinates, a system of geometry that uses points on a grid to describe relationships between shapes. Descartes' scientific work anticipated the development of calculus, and his philosophical ideas paved the way for later thinkers, such as Immanuel Kant and Jean-Paul Sartre.

Descartes died on February 11, 1650, at Stockholm, Sweden, where he had been invited to serve as a military consultant. Despite his untimely death at the age of 53, his legacy continues to shape modern thought, influencing fields as diverse as mathematics, philosophy, and science.
