Abstract

William Lane Craig has defended the following two contentions: (1) If theism is true, we have a sound foundation for morality, and, (2) If theism is false, we do not have a sound foundation for morality. Erik Wielenberg rejects (2). Specifically, Wielenberg argues that naturalists have resources to make sense of objective moral values, moral duties, and moral knowledge. In response to Wielenberg, I defend Craig’s second contention by arguing that Wielenberg’s theory fails to robustly capture our moral phenomenology as well as make intelligible robust moral knowledge.
