Comte, (Isidore-) Auguste (-Marie-François-Xavier)

(born Jan. 19, 1798, Montpellier, France—died Sept. 5, 1857, Paris) French thinker, the philosophical founder of sociology and of positivism. A disciple of Henri de Saint-Simon, he taught at the École Polytechnique (1832–42) but gave free lectures to workingmen. He gave the science of sociology its name and established the new subject on a conceptual (though not empirical) basis, believing that social phenomena could be reduced to laws just as natural phenomena could. His ideas influenced John Stuart Mill (who supported him financially for many years), , Herbert Spencer, and Edward Burnett Tylor. His most important works are Cours de philosophie positive (6 vol., 1830–42) and Système de politique positive (4 vol., 1851–54).
