Now, what will be the attitude of these augmenting black masses toward white political dominion? To that momentous query no certain answer can be made. One thing, however, seems clear: the black world's reaction to white ascendancy will be markedly different from those of the brown and yellow worlds, because of the profound dissimilarities between negroes and men of other stocks. To begin with, the black peoples have no historic pasts. Never having evolved civilizations of their own, they are practically devoid of that accumulated mass of beliefs, thoughts, and experiences which render Asiatics so, impenetrable and so hostile to white influences. Although the white race displays sustained constructive power to an unrivalled degree, particularly in its Nordic branches, the brown and yellow peoples have contributed greatly to the civilization of the world and have profoundly influenced human progress. The negro, on the contrary, has contributed virtually nothing. Left to himself, he remained a savage, and in the past his only quickening has been where brown men have imposed their ideas and altered his blood. The originating powers of the European and the Asiatic are not in him. This lack of constructive originality, however, renders the negro extremely susceptible to external influences. The Asiatic, conscious of his past and his potentialities, is chary of foreign innovations and refuses to recognize alien superiority. The negro, having no past, welcomes novelty and tacitly admits that others are his masters. Both brown and white men have been so accepted in Africa. The relatively faint resistance offered by the naturally brave blacks to white and brown conquest, the ready reception of Christianity and Islam, and the extraordinary personal ascendancy acquired by individual Arabs and Europeans, all indicate a willingness to accept foreign tutelage which in the Asiatic is wholly absent. The Arab and the European are, in fact, rivals for the mastership of black Africa. The Arab had a long start, but the European suddenly overtook him and brought not only the blacks but the African Arabs themselves under his sway. It remains to be seen whether the Arab, allying himself with the blacks, can oust his white rival. That some such move will be attempted, in view of the brown world's renaissance in general and the extraordinary activity of the Arab peoples in particular, seems a foregone conclusion. How the matter will work out depends on three things: (1) the brown man's inherent strength in Africa; (2) the possibilities of black disaffection against white tutelage; (3) the white man's strength and power of resistance.
