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 LockeHe that in the ordinary affairs of life would admit of nothing but direct plain demonstration would be sure of nothing in this world but of perishing quickly.
John LockeWe are all a sort of chameleons, that still take a tincture from things near us: nor is it to be wondered at in children, who better understand what they see, than what they hear.
