 It seems clear that no version of the moral argument constitutes a “proof” of God’s existence. Each version contains premises that many reasonable thinkers reject. However, this does not mean the arguments have no force. One might think of each version of the argument as attempting to spell out the “cost” of rejecting the conclusion. Some philosophers will certainly be willing to pay the cost, and indeed have independent reasons for doing so. However, it would certainly be interesting and important if one became convinced that atheism required one to reject moral realism altogether, or to embrace an implausible account of how moral knowledge is acquired. For those who think that some version or versions of the arguments have force, the cumulative case for theistic belief may be raised by such arguments.
