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). Deleuze and Guattari posit that dramatic reterritorialization often follows relative deterritorialization, while absolute deterritorialization is just that... absolute deterritorialization without any reterritorialization. Terminology borrowed from science During the course of their argument, Deleuze and Guattari borrow a number of concepts from different scientific fields. To describe the process of desire, they draw on fluid dynamics, the branch of physics that studies how a fluid flows through space. They describe society in terms of forces acting in a vector field. They also relate processes of their "body without organs" to the embryology of an egg, from which they borrow the concept of an inductor. Reception and influence The philosopher Michel Foucault wrote that Anti-Oedipus can best be read as an "art", in the sense that is conveyed by the term "erotic art." Foucault considered the book's three "adversaries" as the "bureaucrats of the revolution", the "poor technicians of desire" (psychoanalysts and semiologists), and "the major enemy", fascism. Foucault used the term "fascism" to refer "not only historical fascism, the fascism of Hitler and Mussolini...but also the fascism in us all, in our heads and in our everyday behavior, the fascism that causes us to love power, to desire the very thing that dominates and exploits us." Foucault added that Anti-Oedipus is "a book of ethics, the first book of ethics to be written in France in quite a long time", and suggested that this explains its popular success. Foucault proposed that the book could be called Introduction to the Non-Fascist Life. Foucault argued that putting the principles espoused in Anti-Oedipus into practice involves freeing political action from "unitary and totalizing paranoia" and withdrawing allegiance "from the old categories of the Negative (law, limit, castration, lack, lacuna), which western thought has so long held sacred as a form of power and an access to reality." The psychiatrist David Cooper described Anti-Oedipus as "a magnificent vision of madness as a revolutionary force", crediting its authors with using "the psychoanalytic language and the discourse of Saussure (and his successors)" to pit "linguistics against itself in what is already proving to be an historic act of depassment." The critic Frederick Crews wrote that when
