Because, sir, teaching young gentlemen has a dismal effect upon the soul.It exemplifies the badness of established, artificial authority. The pedagogue has almost absolute authority over pupils: he often beats them and insensibly he loses the sense of respect due to them as fellow human beings.He does them harm, but the harm they do him is far greater. He may easily become the all-knowing tyrant, always right, always virtuous; in any event he perpetually associates with his inferiors, the king of his company; and in a surprising short time alas this brands him with the mark of Cain. Have you ever known a schoolmaster fit to associate with grown men?
