 By “fictional discourse” we mean here and in what follows discourse about fictitious objects. Sometimes, the term “fictitious object” is used as synonymous with “nonexistent object”. Here, the term is used in a different sense, namely for objects (characters, things, events etc.) which occur in fictions, i.e., in myths or fairy tales, in fictional novels, movies, operas etc. Pegasus is a fictitious object in this sense (as are Sherlock Holmes and Hamlet) but Vulcan (the hypothetical planet sought by Le Verrier) is not.
