 Le Poidevin defends the first premise of this argument by stating that, while intrinsic probability plausibly depends inversely on the specificity of a claim (the less specific the claim, the more ways there are for it to be true and so the more probable it is that it is true), it is impossible to show that versatile theism is more specific or less specific than its denial. This defense appears to be incomplete, for Le Poidevin never shows that the intrinsic probability of a proposition depends only on its specificity, and there are good reasons to believe that this is not the case (see, for example, Swinburne 2001: 80–102). Le Poidevin could respond, however, that specificity is the only uncontroversial criterion of intrinsic probability, and this lack of consensus on other criteria is all that is needed to adequately defend premise  (1).
