 One of the reasons why there are doubts about the concept of a nonexistent object is this: to be able to say truly of an object that it doesn’t exist, it seems that one has to presuppose that it exists, for doesn’t a thing have to exist if we are to make a true claim about it? In the face of this puzzling situation, one has to be very careful when accepting or formulating the idea that there are nonexistent objects. It turns out that Kant’s view that “exists” is not a “real” predicate and Frege’s view, that “exists” is not a predicate of individuals (i.e., a predicate that yields a well-formed sentence if one puts a singular term in front of it), has to be abandoned if one is to accept the claim that there are nonexistent objects.
