Whenever any sufferer of his own accord remits the guilt of homicide to another, under the idea that his act was involuntary, let the perpetrator of the deed undergo a purification and remain in exile for a year, according to law.
Enough has been said of murders violent and involuntary and committed in passion: we have now to speak of voluntary crimes done with injustice of every kind and with premeditation, through the influence of pleasures, and desires, and jealousies.
CLEINIAS: Very good.
ATHENIAN: Let us first speak, as far as we are able, of their various kinds.

The greatest cause of them is lust, which gets the mastery of the soul maddened by desire; and this is most commonly found to exist where the passion reigns which is strongest and most prevalent among the mass of mankind: I mean where the power of wealth breeds endless desires of never-to-be-satisfied acquisition, originating in natural disposition, and a miserable want of education.

Of this want of education, the false praise of wealth which is bruited about both among Hellenes and barbarians is the cause; they deem that to be the first of goods which in reality is only the third.

And in this way they wrong both posterity and themselves, for nothing can be nobler and better than that the truth about wealth should be spoken in all states--namely, that riches are for the sake of the body, as the body is for the sake of the soul.

They are good, and wealth is intended by nature to be for the sake of them, and is therefore inferior to them both, and third in order of excellence.
This argument teaches us that he who would be happy ought not to seek to be rich, or rather he should seek to be rich justly and temperately, and then there would be no murders in states requiring to be purged away by other murders.
