Is the Foundation of Morality Natural or Supernatural?
Sam Harris and William Lane Craig debated the moot Is the Foundation of Morality Natural or Supernatural? at the University of Notre Dame.
Craig argued that if theism is true, goodness could be identified with God himself. His view is that goodness is best understood in terms of an exemplar, that good is identified with the perfect paradigm of a good person and that the goodness of everything else is measured by its resemblance to this paradigm.
Harris objected that a divine command theory entails that any action at all could be right, no matter how abhorrent. A second line of argument Harris made was his allegation that the Old Testament teaches the permissibility of genocide and slavery.
Harris also argued that: 1. The existence of evil in the world suggests that God does not exist; 2. The doctrine of hell as a place of eternal conscious torment is unjust; 3. The doctrine of exclusivism is unjust; 4. These beliefs are jointly psychopathic.
