 It seems, accordingly, that some claim about the probability of the story’s being true is needed.  One possibility, suggested by some discussions, is that one might claim that rather than the story’s being a remote possibility that has only a minuscule chance of being true, the story represents “a real possibility”, and so has a substantial chance of being true. Thus, while Peter van Inwagen usually talks about his stories’ being true for all anyone knows, he also introduces the distinction between remote possibilities, and real possibilities (2006, Lecture 4, esp. pp. 66–71).
