Descartes \Descartes\ (d[asl]*k[aum]rt") prop. n. Ren['e] Descartes, a French philosopher and mathematician, born 159, died 1650. See biography, below.
Syn: Rene Descartes. [WordNet 1.5] Descartes, Ren['e] (Latinized Renatus Cartesius). Born at La Haye, Touraine, France, March 31, 1596: died at Stockholm, Feb. 11, 1650. A. celebrated French philosopher, founder of Cartesianism and of modern philosophy in general. He was graduated at seventeen from the Jesuit college of La Fl[`e]che, spent five years in Paris (1613-18), and then roamed about in search of knowledge in Germany, Italy, Holland, and Poland. In 1628 he attended the siege of La Rochelle as a volunteer. From 1629 to 1649 he led a retired life in Holland, spreading and defending his philosophical ideas. He finally went to Stockholm on the invitation of Queen Christina of Sweden; five months later he died there of pneumonia. The work that has made him famous as a philosopher is a short treatise entitled "Discours de la m['e]thode" (Leyden, 1637). It was published in French together with three essays in support of his theories, "La dioptrique," "Les m['e]t['e]ores," and "La g['e]om['e]trie." In it he revolutionized the science of thought. Descartes himself published during his lifetime "Meditationes de prima philosophia "(Paris, 1641; Amsterdam, 1642; translated into French, 1647), "Principia philosophiae" (Amsterdam, 1644), "Trait['e] des passions de l'[^a]me" (Amsterdam, 1649), and a polemic pamphlet entitled "Epistola Renati Descartes ad Gisbertum Vo[eum]itum" (Amsterdam, 1643). After his death his friends published his "De l'homme" (1664), "Trait['e] de la formation du foetus" (1664), "Le monde ou trait['e] de la lumi[`e]re de Descartes" (1664), "Lettres" (1657-67), and "Opuscula posthuma, physica et mathematica" (Amsterdam, 1701). Descartes ranked among the foremost mathematicians of his day. A separate reprint was made of his geometry, and the work itself was translated into Latin in 1649, and re[eum]dited in 1659 with notes and comments. In this form it constituted a classic standard throughout Europe, and presented an entirely new basis for the study of algebra and geometry. [Century Dict. 1906]
Unlike Descartes and Leibniz, but like many humanists of the past and present, Messrs.
But to judge by the success that France's lofty rhetoric seems to enjoy, London ought to be sending its brighter young diplomats off to the grandes ecoles for a refresher course on Descartes and Voltaire.
Typical is the familiar chestnut about how Queen Christina invited Rene Descartes to her court and then insisted that he instruct her in philosophy at five in the morning.
