Cervantes induces us to re-examine the problem of reality vs. fiction/fantasy. Indeed the Quijote leads into an extraordinary play of novelistic fiction. However, the boundary lines between fantasy and reality have no precise definition, and this is because Cervantes himself wished it so The literary fictions in the Quijote (fiction out of reality-reality out of fiction- fiction out of fiction) is a game played by the author to introduce an apparent lunatic who will not dicriminate between the limits of his reality (reality out of fiction) and the fictional in this own reading (fiction out of fiction).
This clinical quixotism is but a cervantine play (ludic quixotism) to lead us to a symbolic quixotism: agony after an ideal and trascendental values, and to a search for a project of heroic humanity, a road to liberty and to an illusion of an individual conscience sustained by mystery and by the miracle of a subjective perception of an imaginary world: in other words, of the eternal and immutable.
