Every one of these civilizing agencies is a social structure, and all of them are the products of the one universal process. They represent the products of that intensive activity which results from the primary clash and conflict of the social forces in the fierce grapple of hostile hordes and clans, and the far fiercer battles of developed nations bent on each other's conquest and subjugation. To see all this one has only to read the history of any of the great nations of the world that are leading the civiliza- tion of today. Everyone is familiar with the history of England, for example. No less than four typical social assimilations have taken place on English soil since the earliest recorded annals of that country began. Think of the animosities and hostilities, the bitter race-hatred, the desperate struggles, the prolonged wars, that characterize the history of England. What has become of
