To Prove that every Man who is virtuous is also free (101-105)

But when, after Syleus had bought him, he was sent into the fields, he showed by his actions the indomitable freedom of his nature; for having sacrificed the choicest of the bulls which were there to Jupiter, he made a pretence of a feast, and having drunk a vast quantity of wine at one meal, he lay down very contentedly to digest it;

Shall we then say that he is the slave, or rather the master of his master, when he dares in this manner not only to accost him with such freedom, but even to impose injunctions on him who has purchased him, as if he would beat and insult him if he were to be stubborn and disobedient, and, if he introduced any one to assist him, as if he would destroy them all to a man? Therefore the writings which were delivered respecting this purchase must have been an utter absurdity and a mere joke, since they would be trampled upon by the more effectual power of the slave bought under them, being of less value than unwritten covenants, and being likely to be utterly destroyed by moths, or time, or mould and rust.

But it is not right, some one will say, to bring forward the actions of heroes as proofs of the correctness of an argument, for that they were greater than the common run of human nature, and were more on a par with the heavenly beings themselves, as having been born of a sort of mixed generation, and having sprung from mortal and immortal seed at the same time, being correctly entitled demigods, the mortal part of their composition being tempered by the incorruptible part, so that there is nothing extraordinary in the fact of their having despised those mortals who designed to bring slavery upon them.
