WE have seen the true state emerging through the working of the federal principle, dual in its nature: (1) created by the law of interpenetration, the unifying of difference, and (2) representing the multiple man in his essential nature. Through the further working of this principle the world-state appears. The lesson of the group is imperative for our international relations. No “alliances,” no balance of power, no agreements, no Hague tribunals will now satisfy us; we know that it is only by creating a genuine community of nations that we can have stability and growth—world peace, world progress. What are the contributions of group psychology to the League of Nations? There is no way out of the hell of our present European situation until we find a method of compounding difference. Superficial moralists try to get us to like some other nationality by emphasizing all the things we have in common, but war can never cease until we see the value of differences, that they are to be maintained not blotted out. The white-man’s burden is not to make others like himself. As we see the value of the individual, of every individual, so we must see the value of each nation, that all are needed. The pacifists have wanted us to tolerate our enemies and the more extreme ones to turn the other cheek when smitten. But tolerance is intolerable. And we cannot dwell among enemies. The ideal of this planet inhabited by Christian enemies all turning the cheek does not seem to me a happy one. We must indeed, as the extreme militarists tell us, “wipe out” our enemies, but we do not wipe out our enemies by crushing them. The old-fashioned hero went out to conquer his enemy; the modern hero goes out to disarm his enemy through creating a mutual understanding. The failure of international society in the past is a fact fraught with deep significance: the differences between nations are not to be overcome by one class of people in a country uniting with the same class in another country. The upper classes of Petrograd, Berlin, Paris and London have very much the same manners and habits. This has not brought peace. Artists the world over have a common language. Workingmen have tried to break down international barriers by assuming that their interests were so identical that they could unite across these barriers. But this has failed to bring peace as the other _rapprochements_ have failed. Why? Because they are all on the wrong track. International peace is never coming by an increase of similarities (this is the old-fashioned crowd-philosophy); international peace is coming by the frankest and fullest kind of recognition of our differences. Internationalism and cosmopolitanism must not be confused. The aim of cosmopolitanism is for all to be alike; the aim of internationalism is a rich content of widely varying characteristic and experience.
