Read this passage from narrative of the life of frederick douglass. if the lineal descendants of ham are alone to be scripturally enslaved, it is certain that slavery at the south must soon become unscriptural; for thousands are ushered into the world, annually, who, like myself, owe their existence to white fathers, and those fathers most frequently their own masters. what is one effect of douglass's allusion to the biblical story of the sons of ham in his memoir?
