I’m basically trying to re-create C.S. Lewis’s Moral Argument for the existence of God in a really sloppy way. Ha!
1. There is a universal Moral Law.
2. If there is a universal Moral Law, there is a Moral Law-giver.
3. If there is a Moral Law-giver, it must be something beyond the universe.
4. Therefore, there is something beyond the universe.
Wright, though, was not a materialist, and may want to grant as much, then claim that the something beyond the universe is not God.
But then, what do you call the force beyond the universe attempting to impose moral obligations upon us?
EDIT: I like Gould. Here he is making my point again:
think the attempt of the dissatisfied atheist to salvage the splendor of the religious worldview in a godless world is doomed to fail. The best non-theistic option is some kind of Platonic atheism where objective values are identified with various Platonic Forms or abstract object. The problem is Platonic atheism does not sufficiently ground moral duty, nor does it help in providing an over-arching story or compelling narrative for my life. To see why consider: we owe moral obligations to people, not things. For example, I have a moral obligation to tell you the truth, or to not steal your wallet. I don’t have a moral obligation to my chair to not (say) weigh 500 pounds. But, on the Platonic atheist story, I am told that my moral obligation is to a thing—a Platonic property—and this makes no sense.
