 Abelard solves the problem by taking obedience to God’s will—the hallmark of morally correct behaviour, and itself an instance of natural law—to be a matter of the agent’s intention conforming to a purely formal criterion, namely the Golden Rule (“Do to others as you would be done to”). This criterion can be discovered by reason alone, without any special revelation or religious belief, and is sufficient to ensure the rightness of the agent’s intention. But the resolution of this problem immediately leads to another problem. Even if we grant Abelard his naturalistic ethics, why should an agent care if his or her intentions conform to the Golden Rule? In short, even if Abelard were right about morality, why be moral?
