Ordinary language and scientific language enable us to speak about,
in a singular way (using demonstratives and names), what we
recognize not to exist: fictions, the contents of our
hallucinations, abstract objects, and various idealized but
nonexistent objects that our scientific theories are often couched
in terms of. Indeed, references to such nonexistent
items-especially in the case of the application of mathematics to
the sciences-are indispensable. We cannot avoid talking about such
things. Scientific and ordinary languages thus enable us to say
things about Pegasus or about hallucinated objects that are true
(or false), such as "Pegasus was believed by the ancient Greeks to
be a flying horse," or "That elf I'm now hallucinating over there
is wearing blue shoes." Standard contemporary metaphysical views
and semantic analyses of singular idioms on offer in contemporary
philosophy of language have not successfully accommodated these
routine practices of saying true and false things about the
nonexistent while simultaneously honoring the insight that such
things do not exist in any way at all (and have no properties).
That is, philosophers often feel driven to claim that such objects
do exist, or they claim that all our talk isn't genuine truth-apt
talk, but only pretence. This book reconfigures metaphysics (and
the role of metaphysics in semantics) in radical ways that allow
the accommodation of our ordinary ways of speaking of what does not
exist while retaining the absolutely crucial presupposition that
such objects exist in no way at all, have no properties, and so are
not the truth-makers for the truths and falsities that are about
them.
