Pegasus example: are cases that refer to non-existent objects in everyday language. The problem here is the predicate logical analysis of the corresponding statements. Here the form (Ex) (Fx) (There is an object described by property F) would be needed. However, existence and non-existence would be simultaneously attributed to the object in question. "There is an object that does not exist" is contradictory. On the other hand, the statement "There is a flying horse" is simply wrong. See also existence, existence predicate, non-existence, there is, unicorn example.
