"For all things good and bad to One thou formest,
So that One everlasting reason governs all."
See Bishop Butler's Sermons. Sermon XV., "Upon the Ignorance of Man."
The origin of evil is an old question. Achilles tells Priam (Iliad, 24, 527) that Zeus has two casks, one filled with good things, and the other with bad, and that he gives to men out of each according to his pleasure; and so we must be content, for we cannot alter the will of Zeus. One of the Greek commentators asks how must we reconcile this doctrine with what we find in the first book of the Odyssey, where the king of the gods says, Men say that evil comes to them from us, but they bring it on themselves through their own folly. The answer is plain enough even to the Greek commentator. The poets make both Achilles and Zeus speak appropriately to their several characters. Indeed, Zeus says plainly that men do attribute their sufferings to their gods, but they do it falsely, for they are the cause of their own sorrows.

Epictetus in his Enchiridion (c. 27) makes short work of the question of evil. He says, "As a mark is not set up for the purpose of missing it, so neither does the nature of evil exist in the universe." This will appear obscure enough to those who are not acquainted with Epictetus, but he always knows what he is talking about. We do not set up a mark in order to miss it, though we may miss it. God, whose existence Epictetus assumes, has not ordered all things so that his purpose shall fail. Whatever there may be of what we call evil, the nature of evil, as he expresses it, does not exist; that is, evil is not a part of the constitution or nature of things. If there were a principle of evil (ἀρχή) in the constitution of things, evil would no longer be evil, as Simplicius argues, but evil would be good. Simplicius (c. 34, [27]) has a long and curious discourse on this text of Epictetus, and it is amusing and instructive.
One passage more will conclude this matter. It contains all that the emperor could say ([ii. 11]): "To go from among men, if there are gods, is not a thing to be afraid of, for the gods will not involve thee in evil; but if indeed they do not exist, or if they have no concern about human affairs, what is it to me to live in a universe devoid of gods or devoid of providence? But in truth they do exist, and they do care for human things, and they have put all the means in man's power to enable him not to fall into real evils. And as to the rest, if there was anything evil, they would have provided for this also, that it should be altogether in a man's power not to fall into it. But that which does not make a man worse, how can it make a man's life worse? But neither through ignorance, nor having the knowledge but not the power to guard against or correct these things, is it possible that the nature of the universe has overlooked them; nor is it possible that it has made so great a mistake, either through want of power or want of skill, that good and evil should happen indiscriminately to the good and the bad. But death certainly and life, honor and dishonor, pain and pleasure, all these things equally happen to good and bad men, being things which make us neither better nor worse. Therefore they are neither good nor evil."
The Ethical part of Antoninus' Philosophy follows from his general principles. The end of all his philosophy is to live conformably to Nature, both a man's own nature and the nature of the universe. Bishop Butler has explained what the Greek philosophers meant when they spoke of living according to Nature, and he says that when it is explained, as he has explained it and as they understood it, it is "a manner of speaking not loose and undeterminate, but clear and distinct, strictly just and true." To live according to Nature is to live according to a man's whole nature, not according to a part of it, and to reverence the divinity within him as the governor of all his actions. "To the rational animal the same act is according to nature and according to reason"[A] ([vii. 11]). That which is done contrary to reason is also an act contrary to nature, to the whole nature, though it is certainly conformable to some part of man's nature, or it could not be done. Man is made for action, not for idleness or pleasure. As plants and animals do the uses of their nature, so man must do his ([v. 1]).
