This dissertation examines the general problem of how to give a philosophical account of the nature of representation by looking at three specific philosophies of language and the philosophic treatment of fictional discourse. I argue that Edmund Husserl, Ludwig Wittgenstein, and J. L. Austin all try to give accounts of meaning by arguing for what I call a "closure of meaning" in language. The closure thesis is the claim that some set of criteria can exhaustively determine the ways in which (...) language can be meaningful. This thesis is implicit in Husserl's theory of expressive meaning in the Logical Investigations, in Wittgenstein's picture theory, and in J. L. Austin's pragmatic account of meaning in speech act theory. My general thesis is that the three philosophers in question do not successfully defend the closure thesis for linguistic representation. Since fictional discourse is a source of counterexamples to the closure thesis, I look specifically at two recent philosophical accounts of fiction by David Lewis and John Searle. I criticize these attempts to account for fictional discourse within referential and pragmatic theories of language. Since such attempts are usually part of a closure thesis, my discussion of fiction provides further reasons for doubting the general possibility of accounting for a closure of meaning in language.
