In a loose definition, the “liberal arts” denote college study anchored in preponderantly Western literature, philosophy, and history, with science, mathematics, and foreign languages playing a substantial, though less central, role; in more recent times, the social science subjects–psychology, sociology, political science–have also sometimes been included. The liberal arts have always been distinguished from more specialized, usually vocational training. For the ancient Greeks, the liberal arts were the subjects thought necessary for a free man to study. If he is to remain free, in this view, he must acquire knowledge of the best thought of the past, which will cultivate in him the intellectual depth and critical spirit required to live in an informed and reasonable way in the present.
