Still others, sickened by the utensility (l'ustensilite) of Oedipus, but also by the shoddiness and aestheticism of perversions, reach the wall and rebound against it, sometimes with an extreme violence. Then they become immobile, silent, they retreat to the body without organs, still a territory, but this time totally desert-like, where all desiring-production is arrested, or where it becomes rigid, feigning stoppage: psychosis.
