Having an eye to all these things, the law, like a good archer, should aim at the right measure of punishment, and in all cases at the deserved punishment.

In the attainment of this the judge shall be a fellow-worker with the legislator, whenever the law leaves to him to determine what the offender shall suffer or pay; and the legislator, like a painter, shall give a rough sketch of the cases in which the law is to be applied.

This is what we must do, Megillus and Cleinias, in the best and fairest manner that we can, saying what the punishments are to be of all actions of theft and violence, and giving laws of such a kind as the Gods and sons of Gods would have us give.
If a man is mad he shall not be at large in the city, but his relations shall keep him at home in any way which they can; or if not, let them pay a penalty--he who is of the highest class shall pay a penalty of one hundred drachmas, whether he be a slave or a freeman whom he neglects; and he of the second class shall pay four-fifths of a mina; and he of the third class three-fifths; and he of the fourth class two-fifths.

Now there are many sorts of madness, some arising out of disease, which we have already mentioned; and there are other kinds, which originate in an evil and passionate temperament, and are increased by bad education; out of a slight quarrel this class of madmen will often raise a storm of abuse against one another, and nothing of that sort ought to be allowed to occur in a well-ordered state.

Let this, then, be the law about abuse, which shall relate to all cases: No one shall speak evil of another; and when a man disputes with another he shall teach and learn of the disputant and the company, but he shall abstain from evil-speaking; for out of the imprecations which men utter against one another, and the feminine habit of casting aspersions on one another, and using foul names, out of words light as air, in very deed the greatest enmities and hatreds spring up.
