Wallas shows that Mazzini enormously exaggerated the simplicity of the question. National types are not divided into homogeneous units "by the course of the great rivers and the direction of the high mountains," but are intermingled from village to village. Do the Balkan mountains represent the purposes of God in Macedonia? And for which nationality, Greek or Bulgar? The remedy, as Wallas sees it, for recurring war between nations is an international science of eugenics which might "indicate that the various races should aim, not at exterminating each other, but at encouraging the improvement by each of its own racial type." In this way the emotion of political solidarity can be slowly made possible between individuals of consciously different national types. A political emotion, if it is to do away with war, cannot be created by thwarting the instinct of nationality. It must be based, "not upon a belief in the likeness of individual human beings, but upon the recognition of their unlikeness." We in America have tried to deny the facts of psychology by calling all our newcomers Americans. We have sought to escape our problem by shutting our eyes to the infinite dissimilarity of the individuals in our population. The only direction for hope to travel is that the improvement of the whole species will come rather from "a conscious world-purpose based upon a recognition of the value of racial as well as individual variety than from mere fighting." This is the true internationalism, and it differs as widely from a cosmopolitan blur which "makes" Americans as from the bitter enforced nationality of blood and iron, or spiritual imperial arrogance. I have found a perfectly clear statement of what lies loosely in the mind of modern Americans of mixed race and intense pre-occupation with the game of getting on. I have found it in the editorial columns of a Middle Western paper. The Cedar Rapids _Gazette_ says: EXTINCT AMERICANS "The authorities who fear that the American race will 'die out' may not have noticed that all the ingredients of that race are still being born in Europe at about the usual rate. And, at the worst, if one American race dies out there will be another race as good or better in America to take its place. "Several American races have already died to the extent that the members are no longer to be separately identified and their distinctive ideas no longer exert influence on the county. Among the vanished races are the Pilgrims, the Puritans, the Cavaliers, the Huguenots, the Acadian voyagers, the Knickerbockers, the Pennsylvania and New Jersey Dutch, the pioneer forest tribes of Kentucky, Ohio and southern Indiana, the picturesque Yankee, the southeastern Cracker, the typical Plainsman and Cowboy, each of whom in his time and place was the representative of a small and distinct nationality.
