In a PragerU video, Dennis Prager claims that if God does not exist, then there is no objective basis for morality. Prager, and those who agree with him, should listen to Objectivist philosopher Onkar Ghate’s talk “Religion and Morality,” in which he argues that it is the belief in God that undermines objective morality. If God is the source of morality, Ghate points out, then murder is good — whenever God says it is.
