"Aristotle makes it clear that the slave can only obey or follow orders, but cannot reason his own syllogism. The master reasons and the slave does. For that reason, it is difficult to imagine the slave after working hours except as an animal: resting, eating, roaming around, copulating. But these are not human acts when performed by the after-hours slave since they are not acts that are the end of practical syllogisms and only these are open to the kind of evaluation that Aristotle offers when he talks of practical wisdom and moral virtue."
