Divine Command Theory holds that what is morally right is what is commanded by God. This view faces a form of the Euthyphro dilemma: either God commands actions because they are right, in which case moral standards are independent of God, or actions are right because God commands them, in which case morality appears arbitrary. A currently influential response among theistic philosophers draws on a distinction between moral duties and moral values. On this view, duties arise from God’s commands, while values are understood—following a neo-Platonist approach—to be grounded in God’s nature. Proponents of this account appeal to an analogy with the role of the standard metre in the metric system: just as a metre is defined by reference to a paradigmatic length, so goodness is defined by reference to God’s character. On this basis, they argue that the existence of moral value depends on God’s existence, and that moral objectivity requires theism. We argue, however, that moral language cannot be understood as involving God in a structurally analogous way to the standard metre. Moreover, the neo-Platonist account does not provide a successful explanation of the normativity of moral language.
Büttner et al. (Fri,) studied this question.
