“You go to a great school not so much for knowledge as for arts and habits; for the habit of attention, for the art of expression, for the art of assuming, at a moment’s notice, a new intellectual position, for the art of entering quickly into another person’s thoughts, for the habit of submitting to censure and refutation, for the art of indicating assent or dissent in graduated terms… And above all, you go to a great school for self-knowledge.”
