“Each night the Amir visits a particular wife, or mahal, and receives a very warm welcome from her and from the slaves (i. e. slave girls), who (are) dressed specially for the occasion… If it is the hot weather, they… rub his body with pounded sandalwood and rosewater. Fans are kept going steadily. Some of the slaves chafe the master’s hand and feet, some sit and sing, or play music and dance, or provide other recreation, the wife sitting near him all the time. Then if one of the pretty slave girls takes his fancy, he calls her to him and enjoys her, his wife not daring to show any signs of displeasure, but dissembling, though she will take it out on the slave girls later on.”

For what price, tell me? What did you find in existence worth as much as this human nature? What price did you put on rationality? How many obols did you reckon the equivalent of the likeness of God? How many staters did you get for selling that being shaped by God? God said, Let us make man in our own image and likeness. If he is in the likeness of God, and rules the whole earth, and has been granted authority over everything on earth from God, who is his buyer, tell me? Who is his seller? To God alone belongs this power; or, rather, not even to God himself. For his gracious gifts, it says, are irrevocable. God would not therefore reduce the human race to slavery, since he himself, when we had been enslaved to sin, spontaneously recalled us to freedom. But if God does not enslave what is free, who is he that sets his own power above God's?

Context: Ideas made the opposite impact in the Confederacy. Ideological contradictions afflicted the slave system even before the war began. John Brown knew the masters secretly feared their slaves might revolt, even as they assured abolitionists that slaves really liked slavery. One reason his Harpers Ferry raid prompted such an outcry in the South was that slave owners feared their slaves might join him. Yet their condemnations of Brown and the 'Black Republicans' who financed him did not persuade Northern moderates but only pushed them toward the abolitionist camp. After all, if Brown was truly dangerous, as slave owners claimed, then slavery was truly unjust. Happy slaves would never revolt... White Southerners founded the Confederacy on the ideology of white supremacy. Confederate soldiers on their way to Antietam and Gettysburg, their two main forays into Union states, put this ideology into practice: they seized scores of free black people in Maryland and Pennsylvania and sold them south into slavery. Confederates maltreated black Union troops when they captured them.
