 One problem has to do with the fact that there is often no single shared description for certain fictions. Even a simple case like ‘Santa Claus’ presents difficulties here. Many people will associate many different descriptions with the name ‘Santa Claus’. Which, if any of those descriptions is the correct one, and in what sense can we say that all the people deploying the name ‘Santa Claus’ and associating different descriptions with the term are talking about the same thing? Complicating the matter further, others might not use the term ‘Santa Claus’ but a name like ‘Saint Nick’ or ‘Babbo Natale’, and associate those terms with descriptions that converge to some degree with typical Santa descriptions.
