 Drawing on concepts found in possible world theory, theorists of fiction study the relationships between textual worlds and the world outside the text.The overarching idea in fiction theory is that the relationships between the imaginary worlds of fiction and the actual world in which we live are complicated, and that one ought not dismiss fiction as simply stories that are not “true.” Theorists of fiction pose challenging questions about, and offer constructive ways of exploring, the often complex relations between the worlds of fiction and the “real” world in which we live.In order to understand fiction theory, one must pose questions about fundamental terms such as text, narrative, literature, fiction, etc.
