Philosopher, b. at Thiers, Department of Puy-de-Dôme, 18 July, 1825; d. at Paris, 13 June, 1899. He received his education in the college of his native city and in the Collège Stanislas (Paris), where, at the age of nineteen, immediately after completing his studies, he was appointed professor. In accordance with. the wishes of his father, he applied himself first to the study of law, but his own inclinations led him in another direction, and he finally decided to devote himself to philosophy. He was appointed to the chair of philosophy in the Collège Stanislas (1849), received the Doctorate (1852), and was made professor of philosophy successively in the Lycée de Rennes (1854), the University of Clermont-Ferrand (1855), the Lycée Napoleon, Paris (1858) and the Collège de France (1874). Nourrisson obtained three prizes in competitions on the philosophy of Leibniz (1860), and on the role of psychology in the philosophy of St. Augustine (1864), subjects proposed by the Institut de France. In 1870 he became a member of the Académie des Sciences morales et politiques in the section of philosophy. Nourrisson was one of the best representatives of French spiritualistic philosophy in the nineteenth century. Not only was he a deep thinker, a penetrating philosopher and historian, but a firm believer, convinced that "conscience remains hesitating, and that convictions come to nothing, unless the teachings of religion complete the data of reason" (letter to de Barante, 5 Dec., 1856.
