Social and economic questions seem to be inseparably mingled with international ones. The solution in each case lies in an appeal to that same spirit of service which can enter and inspire the human heart. The distrust, intractability and egotism of nations reflects and is reflected by the distrust, intractability and egotism of the individual owner and worker in the face of the common good. Exaggerations of possessiveness in the individual are parallel and of a piece with the clutching greed of nations and emperors. They are products of the same instinctive tendencies, and the same ignorances and traditions. Internationalism is the socialism of nations. No one who has wrestled with these problems can feel that there yet exists a sufficient depth and strength of psychological science and a sufficiently planned-out educational method and organization for any real and final solution of these riddles of human intercourse and cooperation. We are as incapable of planning a really effective peace organization of the world to-day as were men in 1820 to plan an electric railway system, but for all we know the thing is equally practicable and may be as nearly at hand. No man can go beyond his own knowledge, no thought can reach beyond contemporary thought, and it is impossible for us to guess or foretell how many generations of humanity may have to live in war and waste and insecurity and misery before the dawn of the great peace to which all history seems to be pointing, peace in the heart and peace in the world, ends our night of wasteful and aimless living. Our proposed solutions are still vague and crude. Passion and suspicion surround them. A great task of intellectual reconstruction is going on, it is still incomplete, and our conceptions grow clearer and more exact—slowly, rapidly, it is hard to tell which. But as they grow clearer they will gather power over the minds and imaginations of men. Their present lack of grip is due to their lack of assurance and exact rightness. They are misunderstood because they are variously and confusingly presented. But with precision and certainty the new vision of the world will gain compelling power. It may presently gain power very rapidly. And a great work of educational reconstruction will follow logically and necessarily upon that clearer understanding. LX THE EXPANSION OF THE UNITED STATES
