Helvetius (Claude Adrien) French philosopher, b. Paris 18 Jan. 1715. Descended from a line of celebrated physicians, he had a large fortune which he dispensed in works of benevolence. Attracted by reading Locke he resigned a lucrative situation as farmer-general to devote himself to philosophy. In August 1758 he published a work On the Mind (De L'Esprit) which was condemned by Pope Clement XIII, 31 Jan. 1759, and burnt by the order of Parliament 6 Feb. 1759 for the hardihood of his materialistic opinions. Mme. Du Deffand said "he told everybody's secret." It was republished at Amsterdam and London. He also wrote a poem On Happiness and a work on Man his Faculties and Education. He visited England and Prussia and became an honored guest of Frederick the Great. Died 26 Dec. 1771.
