In his essay El Quijote como juego Torrente Ballester emphasizes in the Cervantes's novel the lutic attitude of Alonso Quijano who with the help of the words creates a universe and a hero, don Quijote. With a similar strategy Torrente writes his novel La saga/fuga de J.B. whose protagonist José Bastida seems to be a marginal character, but at the end he becomes the main hero and also the narrator and creator of the fictitious universe.
Thanks to the most powerful weapon: the imagination.
