The author offers a firsthand, moral indictment of slavery, opening with a preface that frames his aim to examine whether slavery can coexist with Christian principles. Through vivid scene-setting of a Southern auction hall—its polished comforts, the proprietor and auctioneer, and the assembled slaves presented for sale—he juxtaposes genteel surroundings with human degradation. Eyewitness narrative follows the crowd and the enslaved individuals, recounting familial separations and the inner conscience of owners, and develops ethical arguments that slavery corrupts religion, destroys family life, and contradicts civilization and Christian redemption.
