Dialogues of Plato - MobileReference [319]
If a man do not commit a murder with his own hand, but contrives the death of another, and is the author of the deed in intention and design, and he continues to dwell in the city, having his soul not pure of the guilt of murder, let him be tried in the same way, except in what relates to the sureties; and also, if he be found guilty, his body after execution may have burial in his native land, but in all other respects his case shall be as the former; and whether a stranger shall kill a citizen, or a citizen a stranger, or a slave a slave, there shall be no difference as touching murder by one's own hand or by contrivance, except in the matter of sureties; and these, as has been said, shall be required of the actual murderer only, and he who brings the accusation shall bind them over at the time. If a slave be convicted of slaying a freeman voluntarily, either by his own hand or by contrivance, let the public executioner take him in the direction of the sepulchre, to a place whence he can see the tomb of the dead man, and inflict upon him as many stripes as the person who caught him orders, and if he survive, let him put him to death. And if any one kills a slave who has done no wrong, because he is afraid that he may inform of some base and evil deeds of his own, or for any similar reason, in such a case let him pay the penalty of murder, as he would have done if he had slain a citizen. There are things about which it is terrible and unpleasant to legislate, but impossible not to legislate. If, for example, there should be murders of kinsmen, either perpetrated by the hands of kinsmen, or by their contrivance, voluntary and purely malicious, which most often happen in ill-regulated and ill-educated states, and may perhaps occur even in a country where a man would not expect to find them, we must repeat once more the tale which we narrated a little while ago, in the hope that he who hears us will be the more disposed to abstain voluntarily on these grounds from murders which are utterly abominable. For the myth, or saying, or whatever we ought to call it, has been plainly set forth by priests of old; they have pronounced that the justice which guards and avenges the blood of kindred, follows the law of retaliation, and ordains that he who has done any murderous act should of necessity suffer that which he has done. He who has slain a father shall himself be slain at some time or other by his children--if a mother, he shall of necessity take a woman's nature, and lose his life at the hands of his offspring in after ages; for where the blood of a family has been polluted there is no other purification, nor can the pollution be washed out until the homicidal soul which did the deed has given life for life, and has propitiated and laid to sleep the wrath of the whole family.
