Divine command theory and the (supposed) incoherence of self-commanding

Abstract

Abstract Theological voluntarism is a family of metaethical views that share the claim that deontological statuses of actions are dependent on or identical with some divine feature. Adams's version of this theistic metaethical view is a divine command theory (DCT). According to Adams's DCT, the property being-morally-obligated is identical to the property being-commanded-by-God. Thus, a natural consequence of Adams's DCT is that an agent is morally obligated to do something just in case God commands that agent to do such a thing. From Adams's DCT, it follows that God is morally obligated to act just in case God commands himself to act. Quinn argued that commanding oneself is incoherent and, therefore, that God cannot be morally obligated to act. The claim that commanding oneself is incoherent has seldom been discussed in the divine command theory literature. This article is an attempt to change that. Here, I argue (contra Quinn) that that no constitutive rule (or condition of satisfaction) of self-commands is incoherent, from which it follows that self-commanding is not an incoherent speech act. I conclude that divine command theorists can, without the charge of incoherence, affirm that God can be morally obligated because God can command himself.
