We seem to have forgotten that the expression "a liberal education" originally meant among the Romans one worthy of free men; while the learning of trades and professions by which to get your livelihood merely, was considered worthy of slaves only. But taking a hint from the word, I would go a step further and say, that it is not the man of wealth and leisure simply, though devoted to art, or science, or literature, who, in a true sense, is liberally educated, but only the earnest and free man.
