A quote
Finally, the saying, in allusion to this same high-handed treatment, becomes current: “As many enemies as you have slaves.” They are not enemies when we acquire them; we make them enemies. I shall pass over other cruel and inhuman conduct towards them; for we maltreat them, not as if they were men, but as if they were beasts of burden. When we recline at a banquet, one slave mops up the disgorged food, another crouches beneath the table and gathers up the left-overs of the tipsy guests.
