Capitalism and the political economy of desire
Territorialisation, deterritorialisation, and reterritorialisation
coding decoding & recoding
Although (like most Deleuzo-Guattarian terms) deterritorialization has a purposeful variance in meaning throughout their oeuvre, it can be roughly described as a move away from a rigidly imposed hierarchical, arborescent context, which seeks to package things (concepts, objects, etc.) into discrete categorised units with singular coded meanings or identities, towards a rhizomatic zone of multiplicity and fluctuant identity, where meanings and operations flow freely between said things, resulting in a dynamic, constantly changing set of interconnected entities with fuzzy individual boundaries.
Importantly, the concept implies a continuum, not a simple binary - every actual assemblage (a flexible term alluding to the heterogeneous composition of any complex system, individual, social, geological) is marked by simultaneous movements of territorialization (maintenance) and of deterritorialization (dissipation).
Various means of deterritorializing are alluded to by the authors in their chapter "How to Make Yourself A Body Without Organs" in A Thousand Plateaus, including psychoactives such as peyote. Experientially, the effects of such substances can include a loosening (relative deterritorialization) of the worldview of the user (i.e. his/her beliefs, models, etc.), subsequently leading to an antiredeterritorialization (remapping of beliefs, models, etc.) that is not necessarily identical to the prior territory.
Deterritorialization is closely related to Deleuzo-Guattarian concepts such as line of flight, destratification and the body without organs/BwO (a term borrowed from Artaud), and is sometimes defined in such a way as to be partly interchangeable with these terms (most specifically in the second part of Capitalism and Schizophrenia, A Thousand Plateaus).
The authors posit that dramatic reterritorialization often follows relative deterritorialization, while absolute deterritorialization is just that... absolute deterritorialization without any reterritorialization.
