 The expression “according to the story \(S\)” is the so-called “story  operator”,[10]  which is a sentence operator (that is, it is the sentence as a whole that is in its scope, not just a part of the sentence, for instance the predicate). While the sentence within the scope of the story operator (here: “Pegasus is a flying horse”) may be false when taken in isolation, the complete sentence may be true. (This strategy is developed in detail in Künne 1990.)
