↑ Culler, Jonathan (2000). Literary Theory: A Very Short Introduction. Oxford University Press. tr. 31. Non-fictional discourse is usually embedded in a context that tells you how to take it: an instruction manual, a newspaper report, a letter from a charity. The context of fiction, though, explicitly leaves open the question of what the fiction is really about. Reference to the world is not so much a property of literary [i.e. fictional] works as a function they are given by interpretation.
