edit index René Descartes
René Descartes (31 Mar 1596 - 11 Feb 1650), also known as Renatus Cartesius and dubbed "Father of Modern Philosophy", was a French philosopher crucial to Western Philosophy in the fields of Metaphysics and Philosophy of Mind, and he was a key figure, with Francis Bacon and others, in the Scientific Revolution. Descartes' Meditations on First Philosophy (1642) has become a standard text in many Philosophy courses, and in Mathematics, he established Analytic Geometry, and the Cartesian Coördinate System, Coördinate Algebra, which allows geometric shapes to be expressed in algebraic equations.

Descartes is often cited as a "Continental Rationalist" in American schools, apart from the "British Empiricism begun by Bacon, Hobbes and Locke - merely facile definitions having more exceptions than rules, as later philosophers shared many of Descartes' ideas, including Baruch Spinoza and Gottfried Leibniz, but also John Locke, George Berkeley, and David Hume. Descartes' seminal contribution to Modern Philosophy is his proof of individual existence in the face of radical doubt, "cogito ergo sum", or "I think, therefore, I am."

Life and Works

Descartes was born in La Haye en Touraine (now Descartes, Indre-et-Loire), Indre-et-Loire, France. His Mother, Jeanne Brochard, died of tuberculosis when he was one, and his Father, Joachim, was a member in the provincial parliament. By age eleven, he entered the Jesuit College at La Fleche. After graduation, he studied at the University of Poitiers, earning the Bacalauriat and a License in Law in 1616, as his Father wished he would become an attorney. In 1618 he joined the Army of the Prince of Orange, Maurice of Nassau, in the Dutch Republic. Descartes eventually met Isaac Beeckman, who sparked his interest in Mathematics and the New Physics, such as studies of the falls of heavy bodies. Descartes took part in the Battle of the White Mountain outside Prague, but by 1622 moved on to Paris and travelled Europe. Investments in bonds provided him a comfortable life, yet by 1629 joined the University of Franeker and enrolled at Leiden University in Mathematics, with Jacob Golius and Astronomy with Martin van den Hove. In Amsterdam he had a daughter, Francine, with a servant, Helene Jans, and Descartes died in 1650 from pneumonia during the tutoring of Queen Christina of Sweden.

Descartes' ground-breaking work is due to his provision of the first philosophical framework for Natural Science and a study of the limitations of the senses, and because he arrived at a fundamental, "Archimedian", idea which could not be doubted, even in the face of the strongest possible doubt - that "I exist." Not without dangers, though, by 1633 Galileo Galilei had been condemned by the Roman Catholic Church, and Descartes abandoned plans to publish his Treatise on the World, releasing his "Discourse on the Method" in 1637, and in 1643, Cartesian Philosophy was condemned by the University of Utrecht, and Descartes began his long correspondence with Princess Elisabeth of Bohemia, and awarded a pension by the King of France.

Like Thomas Hobbes, Descartes reasoned that the Body works like a Machine, a result of the material properties of extension and motion following the laws of Physics. The Mind, or Soul, is a mental, non-material "entity" lacking such extension or motion. Descartes argued that only humans have Mind, and its connection to the Body is through a "pineal gland". Dualism was a result, not unlike the separation inherited from Plato, but more akin to the spiritual distinction from Medieval Philosophy. Cartesian Dualism literally dominates philosophical discussion to the present day, and his Analytic Geometry allowed Calculus, independently co-founded by Newton and Leibniz, to be developed, applying infinitesimals to the tangent line.
