This argument has some initial plausibility. Nonetheless, I think it is fallacious. We get a strong hint that something has gone wrong if we pay attention to a certain symmetry. Let , , …, be the actually existing universes, and for i =, , …, , let Ei be the proposition that if some universe is life-permitting then i is life-permitting. Thus, E is equivalent to the conjunction of E’ and . According to White, if all we knew was E’ then that would count as evidence for M; but if we know the more specific E then that is not evidence for M. So he is committed to the following ((White 2000), p. 264):
,
