Signs and Machines: Capitalism and the Production of Subjectivity (published in English in 2014) is Lazzarato's most theoretically ambitious book, systematizing the framework he had developed across two decades of work on immaterial labor, debt, and political subjectivity. Drawing on Félix Guattari's machine theory and on Deleuze's analysis of control societies, the book introduces the foundational distinction between social subjection — which produces individuals experiencing themselves as autonomous subjects — and machinic enslavement, which integrates human capacities directly into technical systems below conscious awareness. The framework has proven indispensable for analyzing how AI platforms operate, producing the experience of voluntary creative collaboration while simultaneously extracting cognitive and behavioral data through infrastructure users cannot see.
The book extends Lazzarato's earlier work on immaterial labor into a general theory of how capitalism produces subjectivity through semiotic operations. It distinguishes signifying semiotics — the communication of meaning between autonomous subjects — from asignifying semiotics, which operate directly on human capacities through technical infrastructure without passing through conscious interpretation.
The AI moment makes the book's framework empirically visible to populations far beyond the academic audience that first engaged it. When users interact with large language models, both semiotic operations occur simultaneously: the interface produces meaning through conventional signification (the user understands the machine's responses), while the infrastructure captures cognitive patterns through asignifying operations (data flows that do not require the user's interpretation to function).
The book emerged from Lazzarato's engagement with Guattari's work during the 1980s and 1990s, and from his subsequent collaboration with post-autonomist thinkers in France and Italy. Its framework synthesizes insights from semiotics, political economy, and continental philosophy into an analysis of how late capitalism operates on human beings.
Dual mechanism of subjection and enslavement. Capitalism operates simultaneously at the level of consciousness and below it.
Signifying and asignifying semiotics. Two distinct modes of operation — meaningful communication and direct infrastructural capture.
Non-human agency. Machines, institutions, and technical systems exercise real agency in the production of subjectivity.
Production of subjectivity as economic operation. The subject is not prior to capitalism but produced by its operations as one of its principal products.
