Is pretty much the basis for all natural law. Without at least some over arching moral law and law giver, no moral law could exist and no "rights" could either. There is this other dusty old tome called the constitution that outlines the "rights" of people based on logical ideas extrapolated from another dusty old tome, the Declaration of independence. Now I know, you're an atheist and you're a good person and you don't need no God to give you no morality! But what law do you appeal to to tell people that they have rights, that the governments actions are wrong etc? Do you appeal to the Constitution? That's just paper if there is no natural law, and natural law is just a figment of people's imaginations if there is no God.
