The issues that nonexistent entities pose for metaphysics and philosophy of language are among the oldest in philosophy, dating back to Plato and Parmenides. These issues arise because of the very natural view that true statements and false statements have the status they have only because they are about objects—broadly speaking—and they’re true (or false) depending on whether they describe those objects correctly or not. If, however, statements are about something nonexistent, it seems they cannot be true or false because there is nothing for them to be true or false of—the very phrase “something nonexistent” sounds oxymoronic. It even strikes some that attempts to say something meaningful about a nonexistent object (or some nonexistent objects) cannot succeed because there is nothing for such statements to be about. And yet we say meaningful things about nonexistents daily: “Sherlock Holmes is more famous than any real detective,” “There are as many gods as goddesses in Greek mythology,” “Hob and Nob are thinking about the same nonexistent witch.” The philosophical tangles that arise when trying to explain our talk about the nonexistent show up everywhere in philosophy, and not just in discussions of fictions, hallucinations, or dreams. If one is a proponent of nominalism in philosophy of mathematics, for example, then one has to explain (or explain away) the usefulness, the indispensability even, of mathematical statements, because such statements—on the nominalist’s view—are not about anything real. The literature on the nonexistent is a bewildering maze of strategies for circumventing or dissolving the problem of how we talk about what doesn’t exist. The key to understanding how influential concerns with nonexistence have been in philosophy is seeing the wealth of different solutions (often implicit in a particular philosophical tradition) that have been invented to solve the puzzle of how we talk, think about, and even perceive what does not exist.

General Overviews

A general discussion of the philosophical issue of nonexistent objects in the broad sense that we are using here cannot at this time be found either in articles, in books, or online. There are specific online articles, such as Reicher 2010, but despite the breadth of the title (“Nonexistent Objects”) the topic of the article is narrowly focused on Meinongian and Neo-Meinongian solutions to the problem of nonexistent objects.
