Such conclusions as these might at least serve, we should suppose, as a working hypothesis, upon the basis of which we may consider in detail a variety of questions of the day. New problems have arisen before the eyes of the teacher, and indeed obtrude themselves upon all who must take part in the practical life of others. Some of these problems are due to changed external relations of countries to one another. Some are problems of internal adjustment and reconstruction. At least they may so be classified for purposes of discussion. In reality all changes are too closely bound up with one another to allow us to treat them practically as independent. No nation any longer stands alone. Internationalism is an idea that penetrates all other practical ideas. And no internal problems of any nation can be wholly local. The world is in a peculiar but also an inspiring way at the present time a single field of labor for the educational thinker and indeed the teacher in every field of human life. CHAPTER IV PEACE AND MILITARISM Among the many pedagogical questions raised and given new significance by the war, is that of the teaching about war and about peace. This is a question of ideals, and of values and the teaching of history. There are practical and superficial questions to be considered. There are also more profound problems, since all our teaching of good and evil is implicated. Shall we continue, in one moment, to assume that war is the greatest glory in the world, and in the next to condemn it as the greatest of evils? Shall we as teachers take the standpoint of pacifism? Or shall we be still apostles of the heroic order? This is really no simple matter, and it is not one to be laid aside, directly it begins to disturb us, as unimportant. No one passing through the experiences of the past four years can have wholly escaped this dilemma, or can have kept himself entirely aloof from the doubts and perplexities that must always be attached to religious and philosophical problems of good and evil. These doubts and hesitations are necessarily increased when we try to become consistent teachers and wise counselors of the young. It would be of psychological interest at least to collect all the arguments and opinions that have been put forth about the good and evil of war. There is a tendency for moralists to go to extremes. The writers on war are likely to be either ardent pacifists or strong militarists. They do not try to strike a balance between good and evil, but war is either a great blessing upon mankind or the greatest curse of the ages. In general they do not seek to base their conclusions upon ultimate philosophical principles, but rather upon moral or biological principles, or, again, upon preferences for the activities of war or the arts of peace. How very different the good and evil of war and peace may seem from different points of view is well shown by the following excerpt from a daily newspaper:
