Relying heavily on Guattari and assemblage theory, Lazzarato offers asignifying semiotics and other ways humans 'mean' and are subjectivated. His goal is liberation, specifially liberation from 'the linguistic turn' which he sees as limiting. He offers 'social subjection and machinic enslavement' as the fulcrum to leverage system-change.
Though the book is very dense at times, the thesis peaks through: "To do so, it is not enough to 'liberate' speech from the apparatuses of power; it must be constructed. That is when the networks of power are confronted with a completely new situation"(p.149). He uses Foucault's 'parrhesia' as a form of truth-telling that would provide a rupture in the assemblage that reproduces the docile subject: "Parrhesia constitutes a rupture with the dominant significations, an 'irruptive event' that creates a 'fracture' by creating both new possibilities and a 'field of dangers.' The performative, on the other hand, is always more or less strictly institutionalized such that its "conditions" as well as its 'effects' are 'known in advance.' In this way, it is impossible to produce any kind of rupture in the assignment of roles and distribution of rights (to speak). The irruption of true discourse 'determines an open situation, or rather opens the situation and makes possible effects which are, precisely, not known.' Inversely, the conditions and the effects of the performative enunciation are 'codified'" (p.173).
