Anti-Oedipus: Anti-Oedipus: Capitalism and Schizophrenia (French: "Capitalisme et schizophrénie.  L'anti-Œdipe" ) is a 1972 book by French authors Gilles Deleuze and Félix Guattari, respectively a philosopher and a psychoanalyst.  It is the first volume of "Capitalism and Schizophrenia", the second being "A Thousand Plateaus" (1980).

Gilles Deleuze: Gilles Deleuze (] ; 18 January 1925 – 4 November 1995) was a French philosopher who, from the early 1960s until his death in 1995, wrote on philosophy, literature, film, and fine art.  His most popular works were the two volumes of "Capitalism and Schizophrenia": "Anti-Oedipus" (1972) and "A Thousand Plateaus" (1980), both co-written with psychoanalyst Félix Guattari.  His metaphysical treatise "Difference and Repetition" (1968) is considered by many scholars to be his magnum opus.  A. W. Moore, citing Bernard Williams's criteria for a great thinker, ranks Deleuze among the "greatest philosophers".  His work has influenced a variety of disciplines across philosophy and art, including literary theory, post-structuralism and postmodernism.

A New Philosophy of Society: A New Philosophy of Society: Assemblage Theory and Social Complexity is a 2006 book by Manuel DeLanda.  The book is an attempt to loosely define a new ontology for use by social theorists — one that challenges the existing paradigm of meaningful social analyses being possible only on the level of either individuals (micro-reductionism) or "society as a whole" (macro-reductionism).  Instead, the book employs Gilles Deleuze's theory of assemblages from "A Thousand Plateaus" (1980) to posit social entities on all scales (from sub-individual to transnational) that are best analysed through their components (themselves assemblages).

What is Philosophy? (Deleuze and Guattari): What is Philosophy?  (French: "Qu'est-ce que la philosophie?" )  is a 1991 book by French authors Gilles Deleuze and Félix Guattari, respectively a philosopher and a psychoanalyst.

Post-convergent: Post-convergent literally means "after convergence".  Theories of Post Convergence draw on the Material philosophy of Gilles Deleuze and Felix Guatarri, explicated in "A Thousand Plateaus: Anti Oedipus", and its later companion volume "A Thousand Plateaus: Capitalism and Schizophrenia."  The basic concept is to use material thinking to re-examine ontological problems of being.  Post Convergence sets itself against a Cartesian world view, summarised but the edict 'I Think Therefore I am.'  Post convergence interpolates materialist notions of embodied interaction, examining that way that our behaviours, processes and presence in a material world co-shape our relations with each other, our environment, our tools and systems.

Schizoanalysis: Schizoanalysis (French: "schizanalyse" ; "schizo-" from Greek σχίζειν "skhizein", meaning "to split") is a concept created by philosopher Gilles Deleuze and psychoanalyst Félix Guattari and first expounded in their book "Anti-Oedipus" (1972).  Its formulation was continued in their follow-up work, "A Thousand Plateaus".  Schizoanalysis acquires many different definitions during the course of its development in their collaborative work and individually in the work of Guattari.

A Thousand Plateaus: A Thousand Plateaus: Capitalism and Schizophrenia (French: "Mille plateaux" ) is a 1980 philosophy book by French authors Gilles Deleuze and Félix Guattari, respectively a philosopher and a psychoanalyst.  The authors draw upon and discuss the work of a number of authors, including Sigmund Freud, Carl Jung, and Wilhelm Reich.  "A Thousand Plateaus" is written in a non-linear fashion, and the reader is invited to move among plateaux in any order.  It is the second volume of "Capitalism and Schizophrenia", and the successor to "Anti-Oedipus" (1972).  Before the full English translation by social theorist Brian Massumi appeared in 1987, the twelfth "plateau" was published separately as "Nomadology: The War Machine" (New York: Semiotext(e), 1986).  Though influential, and considered a major statement of post-structuralism and postmodernism, the book has been criticized on many grounds.

Capitalism and Schizophrenia: Capitalism and Schizophrenia (French: "Capitalisme et Schizophrénie" ) is a two-volume theoretical work by the French authors Gilles Deleuze and Félix Guattari, respectively a philosopher and a psychoanalyst.  Its volumes, published eight years apart, are "Anti-Oedipus" (1972, trans.  1977) and "A Thousand Plateaus" (1980, trans.  1987).  Deleuze's translator Brian Massumi observes that the books differ drastically in tone, content, and composition.

Affect (philosophy): Affect (from Latin "affectus" or "adfectus") is a concept, used in the philosophy of Baruch Spinoza and elaborated by Henri Bergson, Gilles Deleuze and Félix Guattari, that places emphasis on bodily experience.  For Spinoza, as discussed in Parts Two and Three of his "Ethics", affects are states of mind and body that are related to (but not exactly synonymous with) feelings and emotions, of which he says there are three primary kinds: pleasure or joy ("laetitia"), pain or sorrow ("tristitia") and desire ("cupiditas") or appetite.  Subsequent philosophical usage by Gilles Deleuze, Félix Guattari and their translator Brian Massumi, while derived explicitly from Spinoza, tends to distinguish more sharply than Spinoza does between affect and what are conventionally called emotions.  Affects are difficult to grasp and conceptualize because, as Spinoza says, "an affect or passion of the mind ["animi pathema"] is a confused idea" which is only perceived by the increase or decrease it causes in the body's vital force.  The term "affect" is central to what has become known as the "affective turn" in the humanities and social sciences.
