Condorcet, Marie Jean Antoine Nicolas de Caritat, marquis de (Marquess of)[kõdaw(r)say]
French statesman, philosopher, and mathematician, born in Ribemont, N France. He studied at Paris, and his work in mathematics became highly regarded in the 1760s. At the Revolution he made eloquent speeches and wrote famous pamphlets on the popular side, was sent to the Legislative Assembly (1791), and became its president, siding usually with the Girondists. Accused and condemned by the extreme party, he was captured, and found dead in prison. In his philosophy, he proclaimed the ideal of progress, and the indefinite perfectibility of the human race.
