The body without organs (or BwO; French: corps sans organes or CsO) is a fuzzy concept used in the work of French philosophers Gilles Deleuze and Félix Guattari. The concept describes the unregulated potential of a body—not necessarily human[2]— without organizational structures imposed on its constituent parts, operating freely.
Stemming from the general abstract notion of the body in metaphysics, and the unconscious in psychoanalysis, Deleuze and Guattari theorized that since the conscious and unconscious fantasies in psychosis and schizophrenia express potential forms and functions of the body that demand it to be liberated, the reality of the homeostatic process of the body is that it is limited by its organization and more so by its organs. There are three types of the body without organs; the empty, the full, and the cancerous, according to what the body has achieved.
