Abstract

Stephen Law has recently offered an argument against the rationality of certain religious beliefs that he calls the X-claim argument against religious beliefs. The argument purports to show that it is irrational to believe in the existence of extraordinary beings associated with religions. However, the X-claim argument is beset by certain ambiguities that, once resolved, leave the argument undifferentiated from two other common objections to the rationality of religious belief: the objection from religious diversity and the objection from unreliable sources. And though the latter pose serious obstacles to the rationality of religious belief, the X-claim argument adds no further difficulty.
