The laws of Nature, that is to say the laws of God, plainly made every human being a law unto himself, we must steadfastly refuse to obey those laws, and we must as steadfastly stand by the conventions which ignore them, since the statutes furnish us peace, fairly good government, and stability, and therefore are better for us than the laws of God, which would soon plunge us into confusion and disorder and anarchy if we should adopt them.
