A person who wants to be happy must evidently pursue and practice self-control… This is the target which I think one should look to in living, and in his actions he should direct all of his own affairs and those of his city to the end that justice and self-control will be present in one who is to be blessed. He should not allow his appetites to be undisciplined or undertake to fill them up—that’s interminably bad—and live the life of a marauder. Such a man could not be dear to another man or to a god, for he cannot be a partner, and where there’s no partnership there’s no friendship.
