The most striking fact, however, with respect to the question of the relative stability and harmony of the various forms of organization is that the largest and the most permanent relatively harmonious organizations that have appeared among men are those great modern nations whose inhabitants live in a unified area of characterization and are essentially alike in language, race, customs, traditions and religion. Homogeneity in all these respects, it is true, does not as yet exist even on a national scale and there is certainly no prospect of such homogeneity on a world scale in the near future. These considerations must not blind us to the fact, however, that England, France, Spain, Germany, Russia, Italy, the Scandinavian nations, the United States, Japan and China—the largest and internally the most harmonious organizations yet known to man—are each composed of individuals the vast majority of whom are relatively alike in language, customs and traditions, and for the most part in race and religion. Nations that are markedly heterogeneous in the characteristics mentioned, such as the Austro-Hungarian Empire, the Balkan States and European Turkey, are notoriously unstable. Furthermore, the stability possessed by the various utility-form organizations that exist within or among the stable nations of the world is, in large part, the result of the stability and permanence of the nations themselves. The stability of all three of the utility forms thus rests upon the inherent stability of the sympathy type of organization. If the foregoing analysis be correct, certain propositions of great importance for the problem of international peace may now be stated. First, nationality on the basis of sympathy is likely to persist for an indefinite period. Second, because of the ignorance of the inhabitants of a number of important nations, the organizer-force and the organizer-reward forms of government and of business organization are also likely to persist, for a considerable period, in various parts of the globe. Third, where the organizer-force or organizer-reward form of organization is superimposed on nationality, readiness to maintain harmony with other national groups can exist only when such international harmony is to the interest of the organizer class in each of such nations. Where the democratic-control-expert-executive form prevails, readiness to maintain harmony with other national groups can exist only when such international harmony is to the interest of each nation so organized, taken as a whole. [Sidenote: Peace will follow increasing like-mindedness among the nations.]
