" is empty; there is nothing to which it refers. Yet, though there is no Pegasus, we know what the sentence "Pegasus has two wings" means. We can even understand the sentence "There is no such thing as Pegasus." But, what can the meaning of a proper name be, except the object to which it refers?

Overview

There are three broad ways which philosophers have tried to approach this problem. # The meaning of a proper name is not the same as the object (if there is any) it refers to. Hence, though "Pegasus" refers to nothing, it still has a meaning. The German philosopher

". Since there was no such horse, the name has no referent. This is the so-called description theory of names. The difficulty with this account is that we may always use a proper name to deny that the individual bearing the name actually has some characteristic feature. So, we can meaningfully say that Aristotle was not the teacher of Alexander. But if "Aristotle" ''means'' "teacher of Alexander", it would follow that this assertion is self-contradictory, which it is not.

argued, a proper name tells us the identity of its bearer, without telling us anything else about it.

and others. The problem with the direct-reference theory is that names appear to be meaningful independently of whether they are empty. Furthermore, negative existential statements using empty names are both true and apparently meaningful. How can "Pegasus does not exist" be true if the name "Pegasus", as used in that sentence, has no meaning? # There are no empty names. All names have a referent. The difficulty with this theory is how to distinguish names like "Pegasus" from names like "Aristotle". Any coherent account of this distinction seems to require that there are, i.e. there exist, objects that do not exist. Given that "Pegasus does not exist" is true, it follows that the referent of "Pegasus" does not exist. Hence there is something—the referent of "Pegasus"—that does not exist. Some philosophers, such as

have argued that there are two senses of the verb "exists", exemplified by the sentence "there are things that do not exist". The first, signified by "there are", is the so-called "wide sense", including Pegasus, the golden mountain, the round square, and so on. The second, signified by "exist" is the so-called "narrow sense", encompassing only things that are real or existent.

Fictional entities
