The study of anti-illusive and illusive approaches enables one to discover a fundamental aspect of the verisimilitude of literature. Although anti-illusive approaches tend to be considered reflexive passages, one can demonstrate how many narrative passages constitute mere mise-en-scène for reflexion.
It will be apter and more efficient to indicate not the difference between anti-illusive and illusive approaches, but the fact that the two approaches are analogous: it is a matter of a performative utterance, whose believability stems from the figure of the narrator.
