been a growth, and the great characteristic of this growth has been the differentiation of spiritual and mental differences between great races of mankind and the integration of physical differences.
The age of nomadic tribes of closely related individuals represents the maximum of physical differences. They were practically vast families, and there were as many groups as families. As the families came together to form cities the physical differences lessened, purity of blood was replaced by the requirement of domicile, and all who lived within the city bounds became gradually to be regarded as members of the group; i.e., there was a slight and slow breaking down of physical barriers. This, however, was accompanied by an increase of the spiritual and social differences between cities. This city became husbandmen, this, merchants, another warriors, and so on. The IDEALS OF LIFE for which the different cities struggled were different. When at last cities began to coalesce into nations there was another breaking down of barriers which separated groups of men. The larger and broader differences of color, hair and physical proportions were not by any means ignored, but myriads of minor differences disappeared, and the sociological and historical races of men began to approximate the present division of races as indicated by physical researches. At the same time the spiritual and physical differences of race groups which constituted the nations became deep and decisive. The English nation stood for constitutional liberty and commercial freedom; the German nation for science and philosophy; the Romance nations stood for literature and art, and the other race groups are striving, each in its own way, to develop for civilization its particular message, it particular ideal, which shall help to guide the world nearer and nearer that perfection of human life for which we all long, that "one far off Divine event."
This has been the function of race differences up to the present time. What shall be its function in the future? Manifestly some of the great races of today—particularly the Negro race—have not as yet given to civilization the full spiritual message which they are capable of giving. I will not say that the Negro-race has yet given no message to the world, for it is still a mooted question among scientists as to just how far Egyptian civilization was Negro in its origin; if it was not wholly Negro, it was certainly very closely allied. Be that as it may, however, the fact still remains that the full, complete Negro message of the whole Negro race has not as yet been given to the world: that the messages and ideal of the yellow race have not been completed, and that the striving of the mighty Slavs has but begun. The question is, then: How shall this message be delivered; how shall these various ideals be realized? The answer is plain: By the development of these race groups, not as individuals, but as races. For the development of Japanese genius, Japanese literature and art, Japanese spirit, only Japanese, bound and welded together, Japanese inspired by one vast ideal, can work out in its fullness the wonderful message which Japan has for the nations of the earth. For the development of Negro genius, of Negro literature and art, of Negro spirit, only Negroes bound and welded together, Negroes inspired by one vast ideal, can work out in its fullness that great message we have for humanity. We cannot reverse history; we are subject to the same natural laws as other races, and if the Negro is ever to be a factor in the world's history—if among the gaily-colored banners that deck the broad ramparts of civilizations is to hang one uncompromising black, then it must be placed there by black hands, fashioned by black heads and hallowed by the travail of 200,000,000 black hearts beating in one glad song of jubilee.
