CLAUDE, a distinguished writer, born in Poland in 1661, of a French family settled at Rouen, in which city he received his earlier education. He became a Jesuit in 1679, and died at Paris in 1737. There are many works by this author, showing deep penetration and accurate judgment. The principal of these is entitled Un Cours des Sciences, or a Course of Sciences, upon principles new and simple, in order to form the language, the understanding, and the heart. Paris 1732, in folio. He was the author of several other works, particularly Pratique de la Memoire artificielle, Paris, 1716, 4 vols. 12mo; An Introduction to the History of the Sovereign Houses of Europe; An Abridgment of Spanish History; An Account of the Origin of the Kingdom of Sicily and Naples; and various treatises on religion and piety. In his Cours des Sciences Buffier has anticipated, though he failed to develop and pursue to its consequences, that peculiar system of mental philosophy which resolves all the ultimate principles of belief into the perceptions or suggestions of what is called common sense; and indeed it seems pretty certain that Dr Reid has been indebted to the learned Jesuit for valuable hints on nearly all the purely speculative points treated of in his Intellectual Philosophy.
