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 word 'wisdom' mentioned!
