Which of these angles do you find most interesting and useful? Why?

After reading the nature of literature by Jonathan Culler, I found he mention literature as the ‘foregrounding’ of language, literature as the integration of language, literature as fiction, literature as aesthetic object and literature as intertextual or self-reflexive construct. I found literature as fiction most interesting and useful. Nothing could be more interesting as creative a novels by our imagination. A work of a fiction is a work of a literature. Literary traditions are certainly a quality that sets writing separated from other shape of composing. Literature fiction investigates shade of language, subject and imaginary tends to be a character driven instead of plot driven. In fiction the connection of what speaker say to what creators think is a interpretation. I was wondering why readers attend to literature differently that its utterances have a special relation to the world? The relation is called a fictional that include speakers, actors, events and an implied audience and also the fictionality is not limited to characters and events. These are the features of the language related to the situation of utterances.
