The nature of fiction has long been debated across the humanities, and is of considerable importance for philosophical aesthetics, literary theory, narratology and the history of ideas. This volume offers something entirely new: a selection of multidisciplinary perspectives on fiction written by an international team of contributors at the forefront of their fields, providing a spectrum of approaches to compare and contrast. This volume, divided between historical, cognitive, aesthetic and non-western approaches, targets a wide range of topics, including mathematics, history, religion and metaphysics. This is a seminal volume on one of the most important topics in the humanities.
