Paul Janet

Paul Alexandre René Janet (; 30 April 1823 – 4 October 1899) was a French philosopher and writer.

Biography Born in Paris, he became professor of moral philosophy at the University of Bourges (1845–1848) and the University of Strasbourg (1848–1857), and of logic at the Lycée Louis-le-Grand, Paris (1857–1864). In 1864 he was appointed to the chair of philosophy at the Sorbonne, and elected a member of the academy of moral and political sciences.

He wrote widely on philosophy, politics and ethics, on idealistic lines: La Famille, Histoire de la philosophie dans l'antiquité et dans le temps moderne, Histoire de la science politique, and Philosophie de la Révolution Française. However, in the opinion of Encyclopædia Britannica (11th edition, 1911), these writings are not characterised by much originality of thought. In philosophy, he was a follower of Victor Cousin, and through him of G. W. F. Hegel. His principal work, La morale (1874), owes much to Immanuel Kant.

Charles Darwin was familiar with Janet's ideas, but thought that he had not well understood the theory of natural selection, as he indicated in a letter of 1866 to Alfred Russel Wallace: As for M. Janet he is a metaphysician & such gentlemen are so acute that I think they often misunderstand common folk.

Paul was the uncle of Pierre Janet.
