ABOUT RENÉ DESCARTES (1596–1650)
Descartes spent a winter in a stove-heated room in Bavaria thinking through the foundations of knowledge from scratch. He emerged with a method: doubt everything until you reach something indubitable. The result was cogito, ergo sum - I think, therefore I am - the most famous sentence in philosophy and the starting point for an entirely new approach to understanding the world.
His Meditations on First Philosophy, published in 1641, rebuilt the structure of knowledge from that single certainty. He argued for mind-body dualism - the idea that mind and matter are fundamentally different substances - a position that has been debated, defended, and attacked ever since. His emphasis on reason as the path to truth made him the father of rationalism and one of the central figures of the Enlightenment.
He was also a mathematician of extraordinary ability. He invented analytic geometry - the coordinate system that bears his name - which allowed geometric problems to be solved algebraically and algebraic problems to be visualized geometrically. It was a unification that transformed both fields and laid the groundwork for calculus.
He died in Stockholm in 1650 after being invited to tutor Queen Christina of Sweden. She insisted on philosophy lessons at five in the morning in an unheated library. He caught pneumonia and didn't recover. Even the greatest minds are vulnerable to bad working conditions.
