It is one thing to argue that our rights are not God-given and that the Declaration, the founders, Lincoln, Martin Luther King Jr., and so many other great documents and figures in American history were wrong to claim they were. Those who hold this view, of course, need to explain the basis for believing in and protecting unalienable rights and human dignity if they are not grounded in “the Laws of Nature and of Nature’s God.” Absent a Creator, what is the argument against capriciousness, injustice, and tyranny? How does one create a system of justice and make the case against, say, slavery, if you begin with two propositions: one, the universe was created by chance; and two, it will end in nothing? How do you derive a belief in a moral law that is binding on you and others apart from theism? How do you get from the “is” to the “ought”?
