And how is it with the learning of responsibility, with acquiring a sense of duty? Many of us have no doubt learned what we have learned of duty and responsibility, through the constant repetition of "Thou shalt" and "Thou shalt not" by our elders during our own growing years. But results at least as valuable have been obtained in the cases of others through the constant rubbing up against their equals in a free give-and-take atmosphere. Children learn to live with others by living with others. They learn to work with others--to "cooperate"--by working with others. They learn to play the game, to do teamwork, to play fair, to play in good form, to hit hard only by playing according to rule, with others, with worthy opponents, under good supervision. In short, the "discipline" that makes for power and freedom may be quite as easily obtained through the exercise of freedom as through external coercion--nay, more easily, and more effectively. It is fair to ask whether training for a game is not quite analogous to our idea of training for life; and whether the methods which are found to be effective in the former kind of training are not equally valuable for the latter. Assuming the analogy, would you have a child learn the rules of such games as baseball or tennis from a book before allowing him to handle a ball, or before letting him see a game? Would you expect him to cooperate in teamwork after a long period of drill upon the _rules_ governing team cooperation? Would you expect him to hit hard because he has learned the correct answer to the question, How should a player hit?
