Of course, it is more satisfactory to one’s own self-love, to make every one who comes to one to learn, feel that he is a fool, and we wise men; but, if our object is to teach well and usefully what we know ourselves there cannot be a worse method. No man, however, is likely to adopt it, so long as he is conscious that he has anything himself to learn from his pupils; and as soon as he has arrived at the conviction that they can teach him nothing—that it is henceforth to be all give and no take—the sooner he throws up his office of teacher the better it will be for himself, his pupils, and his country, whose sons he is misguiding.
