Understood. In light of that, could it be possible that Natural Law is only one leg of a 3-legged stool that holds a (moral) society together? We know that (immoral) societies do not last, correct?
I don't mean to be pedantic, but I'm not aware of *any* society that "lasts." They all seem to have a life cycle that is accelerated or retarded by certain moral aspects of their existence. What are the other two legs you are refering to?
