 These concepts, and several other networks of concepts considerations of space preclude us from considering, are put to work in addressing the following topics. After a discussion of the notion of “rhizome” in the first chapter (or “plateau” as they call it), Deleuze and Guattari quickly dismiss psychoanalysis in the second. In the third chapter they discuss the process of stratification in physical, organic, and social strata, with special attention to questions in population genetics, where speciation can be thought to stratify or channel the flow of genes. In chapters 4 and 5 they intervene in debates in linguistics in favor of pragmatics, that is to say, highlighting the “incorporeal transformations” (labels that prompt a different form of action to be applied to a body: “I now pronounce you man and wife”) that socially sanctioned “order words” bring about (Deleuze and Guattari also refer to speech act theory in this regard).
