Stephen Darwall has developed an account of moral obligations as grounded in “second-personal reasons,” which was developed in conversation with early modern “theological voluntarists” who were divine command theorists. For Darwall, morality does not require accountability to God; humans as autonomous moral agents are the source of moral obligations. In this paper, I try to show that Darwall is vulnerable to some objections made against divine command theories. There are responses Darwall could make that have parallels to those given by divine command theorists. However, those responses require moral realism, while Darwall’s project is often seen as being inspired by metaethical constructivism. Finally, I suggest that Darwall’s view could be further strengthened by the addition of God to the story.
