Are there nonexistent objects, i.e., objects that do not exist? Some examples often cited are: Zeus, Pegasus, Sherlock Holmes, Vulcan (the hypothetical planet postulated by the 19th century astronomer Le Verrier), the perpetual motion machine, the golden mountain, the fountain of youth, the round square, etc. Some important philosophers have thought that the very concept of a nonexistent object is contradictory (Hume) or logically ill-formed (Kant, Frege), while others (Leibniz, Meinong, the Russell of Principles of Mathematics) have embraced it wholeheartedly. (...) This entry is an examination of the many questions which arise in connection with the view that there are nonexistent objects. The following are particularly salient: What reasons are there (if any) for thinking that there are nonexistent objects? If there are nonexistent objects, then what kind of objects are they? How can they be characterized? Is it possible to provide a consistent theory of nonexistent objects? What is the explanatory force of a consistent theory of nonexistent objects (if such a thing is possible)? (shrink)

Provides a certain conception of the target of a theory of intentionality in terms of five properties (aboutness, non-existence, aspectuality, generality, and semantic normativity) and provides a guided tour of how different styles of theories of intentionality can meet up these requirements.

Meinong’s ‘theory of objects’ is a radicalization of Brentano’s intentionalist theory which widens the universe of objects, since every act has a transcendent object as a correlate. The article focuses on two main issues: on the one hand, the object–as correlate of representations –that might be existent, subsistent or nonexistent ; on the other hand, the ‘objective’–as correlate of judgments and assumptions–; I will argue that the problem of nonexistent objects finds its solution here, i.e. within the sphere of propositional (...) acts. The aim will be to show how an authentic intentionalist theory leads necessarily to a theory of objects that gives an account of every kind of object. (shrink)

The dispute between the Fregean and the Neo-Meinongian approach to existence has become entrenched: it seems that nothing but intuitions may be relied upon to decide the issue. And since contemporary analytic philosophers clearly are inclined towards the intuitions that support Frege's approach, it looks as if Fregeanism has won the day. In this paper, however, I try to develop a compromise solution. This compromise consists in abandoning the assumption shared by both Fregeanism and Neo-Meinongianism, namely that the notion of (...) existence adds something to the content of a statement. To the contrary, we should think of existence as a redundant notion. In other words, I will argue that we should be deflationist about existence. Moreover, the kind of deflationism I propose relies on what I call the existence equivalence schema, a schema which follows the blueprint of the well-known truth equivalence schema. From such a perspective, we can say that Fregean philosophers rightly deny the status of a discriminating property to existence; and, conversely, Neo-Meinongians, too, rightly reject the view that existence is captured by quantification or expresses a universal property of objects. Finally, the argument that we should take a deflationist approach to existence builds upon an analysis of natural language (general) existential statements and their intuitive entailment-relations.
