Thus the law of nature stands as an eternal rule to all men, legislators as well as others. The rules that they make for other mens actions, must, as well as their own and other mens actions, be conformable to the law of nature, i.e. to the will of God, of which that is a declaration, and the fundamental law of nature being the preservation of mankind, no human sanction can be good, or valid against it.
John LockeIn transgressing the law of nature, the offender declares himself to live by another rule than that of reason and common equity.
John Locke
