The 109 answers of the "way of hunting "will wake up the first attention of the readers ready to explore: Autism and schizophrenia; the return of Quetzalcoatl from Venus; the song "The Bonnie Banks of Loch Lomond"; the voyage of Marilyn Monroe on the river of no return; the smile of Mona Lisa; the "eight" arms and "eight" legs of the Vitruvian Man; the friendship of Enkidu and Gilgamesh in ancient Uruk; the union of classical rigidity with quantum flexibility in the Eucharist; the Celtic superposition of the moon with the sun in the Cross chosen by Constantine the Great; the fusion of infinity with zero in any crossing; and the passage from algebraic zero in Euler's identity to transcendental zero in the goring that killed the bullfighter Manolete. In the three labyrinths of THUS RETURNED QUETZALCOATL, Antonio Cassella (DEd) answers 300 questions posed to him by Ligia J. Uribe (BSc) about the esoteric meaning of the Union of the local first attention (the way of hunting and our autistic facet) with the nonlocal second attention (the way of war and our artistic facet) into the Third Attention, the Third Point, and the Way to Progress that follow the return of the Mesoamerican demigod Quetzalcoatl from Venus. Any reader may penetrate in any labyrinth of THUS RETURNED QUETZALCOATL the depths of a theory-of-everything that engages the arts, religion, philosophy, mathematics, natural sciences, social sciences, and politics. The paperback editions of Cassella's writings make the only books in the world that discriminate with underlining, the first attention overdeveloped in high-functioning autism; with the use of bold, the second attention damaged in autism; and by the combination of underlining and bold, the Third Attention impaired in unmedicated schizophrenics. Knowledge of the Third Attention introduces the Third Point by which we WIN WITH the four horsemen of Apocalypse (autism, schizophrenia, global warming, and terror).
