The practice of private individuals, exercising punishment, was the origin of single combats, so familiar to the Germans before the introduction of Christianity, and not yet sufficiently laid aside. We are informed by Velleius Paterculus, in his second book, that the Germans were surprised to see the forms of Roman jurisprudence, and those disputes, which they themselves decided by the sword, settled by law. By the Jewish law, the nearest in blood to the deceased were allowed to kill a murderer, if taken beyond the places of refuge. And the Jewish interpreters observe, that in GENERAL the infliction of punishment, as a retaliation for murder, it intrusted to no hand, but that of the judge: as it is difficult for an individual in his own case to moderate his resentment. The same custom of allowing individuals to avenge their own wrongs prevailed among the ancient Greeks, as we find from the words of Theoclymenes, in Homer's Odyssey. But it prevailed most in countries, where public courts of justice were not established. From hence St. Augustin defines those wars to be just, which are intended to avenge injuries. And Plato, in his twelfth book ON A COMMONWEALTH, justifies the prolongation of hostilities, till the aggressor is reduced to submit to just, and equitable terms. IX. GENERAL utility which was considered as the third end proposed by punishment, may be divided into the same number of parts, as the benefit accruing from thence to individuals. For these are the objects in view, either to prevent the individual, who has injured one person, from doing injury to others: an object which can be accomplished only by removing the offender, disarming him of the means of farther injury, or by reforming him: or it may be inflicted to deter others from being allured, by an example of impunity, to commit acts of molestation or enmity. And the infliction of punishment, for such reasons, is a RIGHT granted by the law of nature to every individual. Upon this principle, Plutarch observes in the life of Pelopidas, that good men are designed by nature for the office of perpetual magistracy, and superiority belongs to those, in whom the characters of truth and justice unite.
