What is easier or cruder to use as a weapon for crushing a rival than the instinctive dislike of man for man? And that usage is not peculiar to the white man. In Africa the black man wastes no time with the different-looking white man; he kills him, if he dares, on the spot. And how ably the Chinaman has employed the instinctive hatred of his countrymen for "foreign devils" in order to fight American trade and traders! We hate the Chinaman and drive him out, and he hates us and drives us out. _Chief Danger of Race Prejudice_ And this is one of the dangers of the race problem in this country--the fostering of such an instinct to make money or to get political office. Such a basis of personal prosperty is all the more dangerous because the white man is in undisputed power in this country; the Negro has no great navy behind him; he is like a child in the house of a harsh parent. All that stands between him and destruction is the ethical sense of the white man. Will the white man's sense of justice and virtue be robust enough to cause him to withhold the hand of unlimited power? Will he see, as Booker T. Washington says, that if he keeps the Negro in the gutter he must stay there with him? The white man and his civilisation, not alone the Negro, will rise or fall by that ethical test. The Negro, on his part, as I have shown repeatedly in former chapters, employs the same methods as the white man, for Negro nature is not different from human nature. He argues: "The white man hates you; hate him. Trade with Negro storekeepers; employ Negro doctors; don't go to white dentists and lawyers." Out of this condition proceed two tendencies. The first is the natural result of mutual fear and suspicion, and that is, a rapid flying apart of the races. All through my former chapters I have been showing how the Negroes are being segregated. So are the Chinese segregated, and the blacks in South Africa, and certain classes in India. Parts of the South are growing blacker. Negroes crowd into "coloured quarters" in the cities. More and more they are becoming a people wholly apart--separate in their churches, separate in their schools, separate in cars, conveyances, hotels, restaurants, with separate professional men. In short, we discover tendencies in this country toward the development of a caste system.
