A bar of music sits before each chapter of Souls — Du Bois is composing as much an oratorio as a book. By the time he reaches the final essay, the argument is unmistakable: the slave song is not a curiosity to be patronised but the United States' singular contribution to the world's art. Whatever else America has produced — vigour, ingenuity, dollars — beauty came to it through the cabin door.
The songs are sorrow songs, but they are not despair. Beneath the minor cadences runs a stubborn faith in ultimate justice — sometimes as life, sometimes as death, sometimes as a fair world beyond — that men will at last be judged by their souls and not their skins. The aesthetic claim is therefore also a theological one: the slaves bequeathed the republic not only its music but its hope.
Du Bois names the gifts the Black population has brought to America: story and song; sweat and brawn that built the economic empire; and a gift of the Spirit — the pleading, generation after generation, that the nation honour Justice, Mercy, and Truth lest it be cursed. The closing question is not rhetorical but accusatory: "Would America have been America without her Negro people?"
From "Of the Sorrow Songs" (Chapter XIV), the closing essay of The Souls of Black Folk.
