AGAINST THE QUARRELSOME AND FEROCIOUS.—The wise and good man neither himself fights with any person, nor does he allow another, so far as he can prevent it. And an example of this as well as of all other things is proposed to us in the life of Socrates, who not only himself on all occasions avoided fights (quarrels), but would not allow even others to quarrel. See in Xenophon’s Symposium how many quarrels he settled, how further he endured Thrasymachus and Polus and Callicles; how he tolerated his wife, and how he tolerated his son who attempted to confute him and to cavil with him. For he remembered well that no man has in his power another man’s ruling principle. He wished therefore for nothing else than that which was his own. And what is this? Not that this or that man may act according to nature, for that is a thing which belongs to another; but that while others are doing their own acts, as they choose, he may nevertheless be in a condition conformable to nature and live in it, only doing what is his own to the end that others also may be in a state conformable to nature. For this is the object always set before him by the wise and good man. Is it to be commander (a prætor) of an army? No; but if it is permitted him, his object is in this matter to maintain his own ruling principle. Is it to marry? No; but if marriage is allowed to him, in this matter his object is to maintain himself in a condition conformable to nature. But if he would have his son not to do wrong or his wife, he would have what belongs to another not to belong to another: and to be instructed is this, to learn what things are a man’s own and what belongs to another.
