William Lane Craig vs. Sam Harris: Is the Foundation of Morality Natural or Supernatural?

Topic: The grounding of objective moral values

Debaters: Dr. William Lane Craig vs. Dr. Sam Harris (neuroscientist and author, "The Moral Landscape")

Held at Notre Dame in 2011 as "The God Debate II," this exchange centers on Harris's claim that science can determine moral values by measuring what promotes "the well-being of conscious creatures." Craig pressed Harris on why well-being should be the standard at all without a transcendent moral lawgiver, and why "is" statements about brain states can generate "ought" statements about how we should live. One of the sharpest available treatments of the is-ought problem.
