[T]here is a connection between the supervaluational approach to vague probability […] and Pascal’s own argument. For Pascal was doing something analogous to supervaluating: the conclusion that one should believe that God exists is supposed to come out true for every probability function (except of course the strict atheistic ones that assign zero to God’s existence) It is presumably in the spirit of Pascal to think of these as different sharp probability functions belonging to different people; but we might equally think of them as different precisifications of the vague opinion of a single person. And just as the strict atheistic probability functions pose a problem for Pascal, so too do the strict atheistic precisifications of a vague opinion concerning God.
