Divine Command Theory, Robust Normative Realism, and the Argument from Psychopathy: A Reply to Erik Wielenberg

Erik Wielenberg has offered a fascinating argument from moral psychology against a sophisticated theistic account of moral obligations: Divine Command Theory (DCT). This argument focuses on the pathology known as psychopathy—a perennial interest for those concerned with abnormal and moral psychology. The argument can be labeled the argument from psychopathy for convenience. The strength of the argument is that it forces the DCT-ist to maintain that there are some human beings who have no moral obligations, yet still do evil actions. This, he argues, is an implausible thesis. Therefore, DCT is false. In this paper, I defend DCT and argue that there is good reason to be neutral or skeptical that psychopaths have moral obligations and, to the degree that they do, they are able to grasp morality in a way consistent with DCT. Furthermore, if the argument does present a serious problem for DCT, then it does so for Wielenberg’s own view, Robust Normative Realism (RNR) just as much as DCT.
