On the title page, Dixon cited Jeremiah 13:23: "Can the Ethiopian change his color, or the Leopard his spots?" He argued that just as the leopard cannot change his spots, the Negro cannot change his nature. The novel aimed to reinforce the superiority of the "Anglo-Saxon" race and advocate either for white dominance of black people or for the separation of the two races. According to historian and Dixon biographer Richard Allen Cook, "the Negro, according to Dixon, is a brute, not a citizen: a child of a degenerate race brought from Africa." Dixon expounded the views in "The Times" of Philadelphia while he discussed the novel in 1902: "The negro is a human donkey. You can train him, but you can't make of him a horse." Dixon described the "towering figure of the freed negro" as "growing more and more ominous, until its menace overshadows the poverty, the hunger, the sorrows and the devastation of the South, throwing the blight of its shadow over future generations, a veritable black death for the land and its people." Using characters from "Uncle Tom's Cabin", he shows the "happy slave" who is now, free and manipulated by carpetbaggers, unproductive and disrespectful, and he believed that freedmen constantly pursued sexual relations with white women. In Dixon's work, the heroic Ku Klux Klan protects American women. "It is emphatically a man's book," said Dixon to "The Times".
