I don’t think it would have all got me quite so down if just once in a while—just once in a while—there was at least some polite little perfunctory implication that knowledge should lead to wisdom, and that if it doesn’t, it’s just a disgusting waste of time. But there never is. You never even hear any hints dropped on a campus that wisdom is supposed to be the goal of knowledge. You hardly ever even hear the world ‘wisdom’ mentioned.
