Abstract

Robert M. Adams (1979, 1987a, 1987b) defends a modified variant of the divine command theory (hereafter MDCT) to the effect that he proposes a moral argument for God’s existence driven in the form of practical reasoning with respect to rational moral agents’ beliefs in the adequacy of MDCT. For Adams, one’s commitment to MDCT as the most adequate theory legitimately provides her a practical reason for why she ought to believe in God’s existence which MDCT implies. In this paper, I criticize the viability of Adams’ moral argument considering its argumentative structure and strategy. Adams’ strategy behind his moral argument, i.e. mediating theistic beliefs with deontic ones, seeks out a non-decisive medium that might be used to ubiquitously generate equally plausible arguments for/against God’s existence based on distinct sorts of allegedly adequate theories of some subject matter. Thus, his argument does not seem to distinctively ground God’s existence in comparison with a myriad of practical arguments which might follow the same argumentative strategy on the same practical grounds. More significantly, there seems to be coherent no way for Adams to disambiguate his argument on theoretical grounds.
