andquot;The unconscious is not a theatre, but a factory,andquot; wrote Gilles Deleuze and Fandeacute;lix Guattari in Anti-Oedipus (1972), instigating one of the most daring intellectual adventures of the last half-century. Together, the well-known philosopher and the activist-psychiatrist were updating both psychoanalysis and Marxism in light of a more radical and andquot;constructivistandquot; vision of capitalism: andquot;Capitalism is the exterior limit of all societies because it has no exterior limit itself. It works well as long as it keeps breaking down.andquot;

Few people at the time believed, as they wrote in the often-quoted opening sentence of Rhizome, that andquot;the two of us wrote Anti-Oedipus together.andquot; They added, andquot;Since each of us was several, that became quite a crowd.andquot; These notes, addressed to Deleuze by Guattari in preparation for Anti-Oedipus, and annotated by Deleuze, substantiate their claim, finally bringing out the factory behind the theatre. They reveal Guattari as an inventive, highly analytical, mathematically-minded andquot;conceptor,andquot; arguably one of the most prolific and enigmatic figures in philosophy and sociopolitical theory today. The Anti-Oedipus Papers (1969-1973) are supplemented by substantial journal entries in which Guattari describes his turbulent relationship with his analyst and teacher Jacques Lacan, his apprehensions about the publication of Anti-Oedipus and accounts of his personal and professional life as a private analyst and codirector with Jean Oury of the experimental clinic Laborde (created in the 1950s).

Notes and journal entries document Guattari and Deleuze's collaboration on their 1972 book Anti-Oedipus.
