“Race feeling is not so much a result of social as of biological evolution. It does not change essentially with changes of economic systems. It is deeper than any class feeling and will outlast the capitalist system. It persists even after race prejudice has been outgrown. It exists not because the capitalists nurse it for economic reasons, but the capitalists rather have an opportunity to nurse it for economic reasons because it exists as a product of biology. It is bound to play a role in the economics of the future society. If it should not assert itself in open warfare under a Socialist form of society, it will nevertheless lead to a rivalry of races for expansion over the globe as a result of the play of natural and sexual selection. We may temper this race feeling by education, but we can never hope to extinguish it altogether. Class-consciousness must be learned, but race consciousness is inborn and cannot be wholly unlearned. A few individuals may indulge in the luxury of ignoring race and posing as utterly raceless humanitarians, but whole races never. Where races struggle for the means of life, racial animosities cannot be avoided. Where working people struggle for jobs, self-preservation enforces its decrees. Economic and political considerations lead to racial fights and to legislation restricting the invasion of the white man’s domain by other races.” It is well that the New Negro should know this, since it justifies him in giving you a taste of your own medicine. The writer of these lines is also a Socialist; but he refuses in this crisis of the world’s history to put either Socialism or your party above the call of his race. And he does this on the very grounds which you yourselves have given in the document quoted above. Also because he is not a fool. —March 27th, 1920. _An Open Letter to the Socialist Party of New York City_
