1838–1912
A self-taught French philosopher who tried to connect ideas, will, and social life, he became best known for his theory of "idées-forces"—the thought that ideas can act as real forces in human behavior. His work moves between philosophy, psychology, morality, and politics with unusual range.

by Alfred Fouillée
Born in La Pouëze, France, on October 18, 1838, Alfred Fouillée was a French philosopher associated with spiritualist and idealist thought. He taught philosophy at several lycées, including in Douai, Montpellier, and Bordeaux, and later held a post at the École Normale Supérieure before poor health pushed him into early retirement.
Fouillée is best remembered for developing the idea of idées-forces, a theory he explored in works such as L'Évolutionnisme des idées-forces, La Psychologie des idées-forces, and La Morale des idées-forces. In broad terms, he argued that ideas are not passive thoughts but can help drive action, character, and social life. He also wrote widely on Plato, Socrates, education, morality, and politics, earning a reputation as a prolific thinker whose work crossed several fields.
He died in Lyon on January 16, 1912. Although he is less widely read today than some of his contemporaries, he remains an interesting figure for listeners curious about nineteenth-century French philosophy and the meeting point between mind, ethics, and society.
