The liberal arts and sciences have no economic value. Let me repeat that: none, nada. Taught in the right spirit, they are useless from an economic point of view. They are designed in fact to be downright wasteful. The liberal arts’ ancient roots, after all, are from a world in which a few free men had the time — the leisure — to engage in study. It was for the elite. The purpose of the liberal arts in ancient times was to offer to the elite the knowledge, morals, and skills (like oratory) that they needed to determine what was good for individuals and the public, and to help achieve that good in society through citizenship.
