 But while this may work for the simplest cases, it is not clear that we can be so sanguine about others. Thus, consider stories like Gendler’s story of the Tower of Goldbach in which \(7+5 ≠ 12\) and \(7+5=12\) (Gendler 2000), or Priest’s story of Sylvan’s box, empty and non-empty at the same time. It is one thing to allow that such contradictory propositions are both true in the relevant story; understanding how it can be reasonable to attribute belief in both propositions to a fictional author may be more difficult. Or consider a story in which everything whatsoever is true (imagine a story in which God or Sylvan discloses this to Priest). Even those who think that there is no bar to believing impossible propositions are likely to reject as incoherent the thought that someone can believe all propositions (cf. Priest 2000).
