The problem of the interplay and interaction of the nations is largely a psychological one. The soul of a nation is potent in its effect. The national thought-form (built up over the centuries by the thinking, the goals and the ambitions of a nation) constitutes its ideal objective and is most effective in conditioning the people. A Pole, a Frenchman, an American, a Hindu, a Britisher or a German are easily recognized, no matter where they may be. This recognition is not based solely upon appearance, intonation or habits but primarily upon the expressed mental attitude, the sense of relativity and a general national assertiveness. These indications express reaction to the particular national thought-form under which the man has been raised. If this reaction makes him a good cooperative citizen within the national boundaries, that is good and to be desired. If it makes him assertive, arrogant, critical of the nationals of other countries and separative in his thinking, he is then contributing to world disunity and, en masse, to international disruption. This menaces the peace of the world. The problem, therefore, becomes one in which all people share. Nations can be (and often are) anti-social [12], and all nations have within them these anti-social elements.

The stage of national selfishness and the fixed determination to preserve national integrity - interpreted often in terms of boundaries and the expansion of trade - must gradually fade out. The nations must pass eventually to a more beneficent realization and come to the point where they regard their national cultures, their national resources and their ability to serve mankind as the contributions which they must make to the good of the whole. Emphasis upon worldly possessions or extensive territory is no sign of maturity; fighting to preserve these or to expand them is a sign of adolescent immaturity. Mankind is now growing up; only now is humanity demonstrating a wider sense of responsibility, of ability to handle its problems or to think in larger terms. The late world war was symptomatic of immaturity, of adolescent thinking, of uncontrolled childish emotions and of a demand - by anti-social nations - for that which does not belong to them. Like children, they cry for "more".
