Among other works, Comte published A General View of Positivism, '48, translated by Dr. Bridges, '65; A System of Positive Polity, '51, translated by Drs. Bridges, Beesley, F. Harrison, etc., '75-79; and A Positive Catechism, '54, translated by Dr. Congreve, '58. He also wrote on Positive Logic, which he intended to follow with Positive Morality and Positive Industrialism. Comte was a profound and suggestive thinker. He resolutely sets aside all theology and metaphysics, coordinates the sciences and substitutes the service of man for the worship of God. Mr. J. Cotter Morison says "He belonged to that small class of rare minds, whose errors are often more valuable and stimulating than other men's truths." He died of cancer in the stomach at Paris, 5 Sept. 1857. Condillac (Etienne Bonnot de), French philosopher, b. Grenoble, about 1715. His life was very retired, but his works show much acuteness. They are in 23 vols., the principal being A Treatise on the Sensations, 1764; A Treatise on Animals, and An Essay on the Origin of Human Knowledge. In the first-named he shows that all mental life is gradually built up out of simple sensations. Died 3 Aug. 1780. Condorcet (Marie Jean Antoine Nicolas Caritat, Marquis de), French philosopher and politician, b. Ribemont, Picardy, 17 Sept. 1743. Dedicated to the Virgin by a pious mother, he was kept in girl's clothes until the age of 11. Sent to a Jesuit's school, he soon gave up religion. At sixteen he maintained a mathematical thesis in the presence of Alembert. In the next year he dedicated to Turgot a Profession of Faith. After some mathematical works, he was made member of the Academy, of which he was appointed perpetual secretary, 1773. In 1776 he published his atheistic Letters of a Theologian. He also wrote biographies of Turgot and Voltaire, and in favor of American independence and against negro slavery. In 1791 he represented Paris in the National Assembly, of which he became Secretary. It was on his motion that, in the following year, all orders of nobility were abolished. Voting against the death of the king and siding with the Gironde drew on him the vengeance of the extreme party. He took shelter with Madame Vernet, but fearing to bring into trouble her and his wife, at whose instigation he wrote his fine Sketch of the Progress of the Human Mind while in hiding, he left, but, being arrested, died of exhaustion or by poison self-administered, at Bourg la Reine, 27 March, 1794.
