God and moral realism

Abstract

Only God, or a very god-like being, can provide both the objectivity and the normative power necessary for a really robust moral realism. Further, I argue that the classical theist position - the view of Augustine, Anselm, and Aquinas - that morality is grounded in the nature of God, supplies a better metaphysical background for a strong moral realism than Divine Command Theory does. I respond briefly to the criticism that belief in God can have no positive role to play in solving ethical problems, and I conclude with the observation that if the argument is correct, it entails that there is an argument from evil for the existence of God.
