Love of goodness without love of learning degenerates into simple-mindedness. Love of knowledge without love of learning degenerates into utter lack of principle.

Love of courage without love of learning degenerates into insubordination. Love of strong character without love of learning degenerates into mere recklessness.

In antiquity men studied for their own sake; nowadays men study for the sake of impressing others.
