W. E. B. DuBois advocated the idea of racial pluralism in virtue of which each race must be free to strive “in its own way, to develop for civilization its particular message, its particular ideal, which shall help guide the world nearer and nearer that perfection of human life, for which we all long, that ‘one far off Divine event’” (From “The Conservation of Races”).

      In The Souls of Black Folk, DuBois is even more emphatic about the peculiarity of the “double-consciousness” situation of the black people in America. He explains: “The history of the American Negro is the history of this strife,--this longing to attain self-conscious manhood, to merge his double self into a better and truer self. In this merging he wishes neither of the older selves to be lost. He would not Africanize America, for America has too much to teach the world and Africa. He would not bleach his Negro soul in a flood of white Americanism, for he knows that the Negro blood has a message for the world. He simply whishes to make it possible for a man to be both a Negro and an American, without being cursed and spit upon by his fellows, without having the doors of Opportunity closed roughly in his face” (From The Souls of Black Folk, A. C. McClurg, 1903).
