Jean Gaspard Felix Ravaisson-Mollien (October 23, 1813 - May 18, 1900) was a French philosopher and archaeologist.
He was born at Namur. After a successful course of study at the College Rollin, he went to Munich, where he attended the lectures of Schelling, and took his degree in philosophy in 1836. In the following year he published the first volume of his famous work Essai sur la métaphysique d'Aristote, to which in 1846 he added a supplementary volume. This work not only criticizes and comments on the theories of Aristotle and the Peripatetics, but also developes from them a modern philosophical system.
In 1838 he received his doctorate, and became professor of philosophy at Rennes. From 1840 he was inspector-general of public libraries, and in 1860 became inspector-general in the department of higher education. He was also a member of the Académie française, and of the Academy of Moral and Political Science, and curator of the Department of Antiquities at the Louvre (from 1870). He died in Paris.
In philosophy, he was one of the school of Victor Cousin, with whom he was at issue in many important points. The act of consciousness, according to him, is the basis of all knowledge. Acts of consciousness are manifestations of will, which is the motive and creative power of the intellectual life. The idea of God is a cumulative intuition given by all the various faculties of the mind, in its observation of harmony in nature and in man. This theory had considerable influence on speculative philosophy in France during the later years of the 19th century.
Ravaisson's chief philosophical works are: "Les Fragments philosophiques de Hamilton" (in the Revue des Deux Mondes, November, 1840); Rapport sur Ie stoicisme (1851); La Philosophie en France au dix-neuvième siècle (1868; 3rd ed, 1889); Morale et métaphysique (1893). Eminent as a philosopher, Ravaisson was also an archaeologist, and contributed articles on ancient sculpture to the Revue Archiologique and the Mémoires de l'Académie des Inscriptions. In 1871 he published a monograph on the Venus de Milo.
