The soul of man does violence to itself, first of all, when it becomes an abscess and, as it were, a tumour on the universe, so far as it can. For to be vexed at anything which happens is a separation of ourselves from nature, in some part of which the natures of all other things are contained. In the next place, the soul does violence to itself when it turns away from any man, or even moves towards him with the intention of injuring, such as are the souls of those who are angry. In the third place, the soul does violence to itself when it is overpowered by pleasure or by pain. Fourthly, when it plays a part, and does or says anything insincerely and untruly. Fifthly, when it allows any act of its own and any movement to be without an aim, and does anything thoughtlessly and without considering what it is, it being right that even the smallest things be done with reference to an end; and the end of rational animals is to follow the reason and the law of the most ancient city and polity.
That which does not make a man worse than he was, also does not make his life worse, nor does it harm him either from without or from within.
That which does no harm to the state, does no harm to the citizen. In the case of every appearance of harm apply this rule: if the state is not harmed by this, neither am I harmed. But if the state is harmed, thou must not be angry with him who does harm to the state. Show him where his error is.
As thou intendest to live when thou art gone out,...so it is in thy power to live here. But if men do not permit thee, then get away out of life, yet so as if thou wert suffering no harm. The house is smoky, and I quit it. Why dost thou think that this is any trouble? But so long as nothing of the kind drives me out, I remain, am free, and no man shall hinder me from doing what I choose; and I choose to do what is according to the nature of the rational and social animal.
If this is neither my own badness, nor an effect of my own badness, and the common weal is not injured, why am I troubled about it? And what is the harm to the common weal?
Where any work can be done conformably to the reason which is common to gods and men, there we have nothing to fear: for where we are able to get profit by means of the activity which is successful and proceeds according to our constitution, there no harm is to be suspected.
Generally, wickedness does no harm at all to the universe; and particularly, the wickedness of one man does no harm to another. It is only harmful to him who has it in his power to be released from it, as soon as he shall choose.
He who fears death either fears the loss of sensation or a different kind of sensation. But if thou shalt have no sensation, neither wilt thou feel any harm; and if thou shalt acquire another kind of sensation, thou wilt be a different kind of living being and thou wilt not cease to live.
If any man has done wrong, the harm is his own. But perhaps he has not done wrong.
