The struggle for the supremacy of the State over other forms of organization was directed against the power of minor districts, provinces, principalities, against the dispersion of power among feudal lords as well as, in some countries, against the pretensions of an ecclesiastic potentate. The "State" represents the conspicuous culmination of the great movement of social integration and consolidation taking place in the last few centuries, tremendously accelerated by the concentrating and combining forces of steam and electricity. Naturally, inevitably, the students of political science have been preoccupied with this great historic phenomenon, and their intellectual activities have been directed to its systematic formulation. Because the contemporary progressive movement was to establish the unified state against the inertia of minor social units and against the ambitions of rivals for power, political theory developed the dogma of the sovereignty of the national state, internally and externally. As the work of integration and consolidation reaches its climax, the question arises, however, whether the national state, once it is firmly established and no longer struggling against strong foes, is not just an instrumentality for promoting and protecting other and more voluntary forms of association, rather than a supreme end in itself. Two actual phenomena may be pointed to in support of an affirmative answer. Along with the development of the larger, more inclusive and more unified organization of the state has gone the emancipation of individuals from restrictions and servitudes previously imposed by custom and class status. But the individuals freed from external and coercive bonds have not remained isolated. Social molecules have at once recombined in new associations and organizations. Compulsory associations have been replaced by voluntary ones; rigid organizations by those more amenable to human choice and purposes--more directly changeable at will. What upon one side looks like a movement toward individualism, turns out to be really a movement toward multiplying all kinds and varieties of associations: Political parties, industrial corporations, scientific and artistic organizations, trade unions, churches, schools, clubs and societies without number, for the cultivation of every conceivable interest that men have in common. As they develop in number and importance, the state tends to become more and more a regulator and adjuster among them; defining the limits of their actions, preventing and settling conflicts.
