"The sixth precept of the natural law is, that in revenge and punishments we must have our eye not at the evil past, but the future good: that is, it is not lawful to inflict punishment for any other end, but that the offender may be corrected, or that others warned by his punishment may become better. But this is confirmed chiefly from hence, that each man is bound by the law of nature to forgive one another, provided he give caution for the future, as hath been showed in the foregoing article. Furthermore, because revenge, if the time past be only considered, is nothing else but a certain triumph and glory of mind, which points at no end (for it contemplates only what is past, but the end is a thing to come), but that which is directed to no end, is vain: that revenge therefore which regards not the future, proceeds from vain glory, and therefore without reason. But to hurt another without reason introduces a war, and is contrary to the fundamental law of nature. It is therefore a precept of the law of nature, that in revenge we look not backwards, but forward. Now the breach of this law is commonly called CRUELTY."
