Now Europe, if it is not to sink down to anarchy, has to do a parallel thing. If Europe is to be saved from ultimate disaster, Europe has to stop thinking in terms of the people of France, the people of England, the people of Germany, the French, the British, the Germans, and so forth. Europe has to think at least of the people of Europe, if not of the civilized people of the world. If we Europeans cannot bring our minds to that, there is no hope for us. Only by thinking of all peoples can any people be saved in Europe. Fresh wars will destroy the social fabric of Europe, and Europe will perish as nations, fighting. There are many people who think that there is at least one political system in the old world which, like the United States, is large enough and world wide enough to go on by itself under modern conditions for some considerable time. They think that the British Empire can, as it were, stand out of the rest of the Old World as a self-sufficient system. They think that it can stand out freely as the United States can stand out, and that these two English-speaking powers have merely to agree together to dominate and keep the peace of the world. Let me give a little attention to this idea. It is I believe a wrong idea, and one that may be very disastrous to our common English-speaking culture if it is too fondly cherished. There can be no denying that the British Imperial system is a system different in its nature and size from a typical European state, from a state of the horse and road scale, like France, let us say, or Germany. And equally it is with the United States a new growth. The present British Empire is indeed a newer growth than the United States. But while the United States constitute a homogeneous system and grow more homogeneous, the British Empire is heterogeneous and shows little or no assimilative power. And while the United States are all gathered together and are still very remote from any serious antagonist, the British Empire is scattered all over the world, entangled with and stressed against a multitude of possible antagonists. I have been arguing that the size and manageability of all political states is finally a matter of transport and communications. They grow to a limit strictly determined by these considerations. Beyond that limit they are unstable. Let us now apply these ideas to the British Empire. I have shown that the great system of the United States is the creation of the river steamboat and the railway. Quite as much so is the present British Empire the creation of the ocean-going steamship--protected by a great navy.
