Some definitions
This is Jonathan Kemp's description of the Body without Organs. "The Body without Organs, as proposed by Antonin Artaud and adopted and developed by Deleuze and Guattari, is a disorganized, deOedipalized body of constantly emergent desire and intensity. It is a passage, a movement, that resists the closure of an organizing principle that would reduce its intensity for the sake of stopping it, freezing it, categorising it (in one of two genders) to understand it. It cannot, however, be understood, at least not by stopping it, because to stop it is to kill it, and the knowledge acquired from a dead BwO is no knowledge at all. It is, as such, a singular multiplicity, resisting both the universalizing gesture of conceptualization and the individualizing gesture of contemporary subjectivity." More of that - and some less reverent stuff - at the deleuzegattarionary.
