One of the things that presents a difficulty in every generation is the fact that the social and moral ideals change from age to age. We are thus constantly tempted to put into the characters of our children those traits that were valued highly by our parents, without always considering the importance of each item for the days in which our children will play their parts. Thus it comes about that many of the virtues that have a traditional value may be questioned when offered as staples for citizens of to-morrow. Obedience, for example, is a permanent necessity in a society that rests upon the assumption that one or a few chosen men represent the will of the gods on earth, but has only a transitory value in a democracy. As someone has said, obedience in childhood must be considered as a scaffold that is useful while the lasting parts of the structure are being put in place; when the desired structure is completed, obedience is naturally removed as of no further service. Now the kind of discipline required in a democracy calls for an attitude or disposition that makes cooperation with others come as a matter of course; it calls for the making of decisions, or the forming of opinions, on the basis of facts; and it calls for the habit of taking due account of the rights of others. The training for this class of habits is best obtained through methods that take full account of children's interests. Just as the older outlook turned to "discipline" as a means for obtaining freedom, the new psychology utilizes freedom as a means for obtaining discipline. In both cases the end is of course the same--that is, the liberation of the human spirit and the organizing of the individual's powers to the greatest good. But as our ideas of human relations and of values have changed, science has given us new methods for attaining the final goals that we set ourselves.
