Reassembling the Social

In the AI Story

The book was written in response to ANT's success as a research tradition and the widespread misuse of its vocabulary. By the early 2000s, 'actor-network' was being invoked as a methodological badge without serious engagement with the analytical discipline the framework required. Latour wrote the book to reassert the discipline: ANT is not a theory that explains things; it is a method that describes things, and the description is only useful if the tracing is honest and the pre-formed categories are refused.

The book's central polemic is against what Latour called 'critical sociology' — the tradition that invokes 'society,' 'power,' 'capitalism,' or 'patriarchy' as explanatory contexts that account for individual behavior. These invocations, Latour argued, are sociology's version of purification: they treat the thing to be explained (the social) as the thing that explains, and in doing so they conceal the specific mechanisms through which social assemblages are produced and reproduced. The alternative is to trace the associations — to describe the concrete chains of action, negotiation, translation, and stabilization that produce what appears as 'the social.'

For the AI moment, the book is foundational reading. Its refusal to treat pre-formed categories as explanatory — its insistence on following the actants and describing the network as it actually operates — is the methodological engine of every claim this book makes about AI. When we say Claude is a mediator rather than an intermediary, we are applying Reassembling the Social's rule to refuse categorical assumptions and trace what Claude actually does. When we say the invisible collective must be made visible, we are applying the same rule to refuse the sovereign-individual category that effaces the network. The book is not about AI, but it provides the method without which AI cannot be honestly described.

The book's five sources of uncertainty — about the nature of groups, of actions, of objects, of facts, and of empirical accounts — provide a checklist for the analyst. Each uncertainty names a place where the researcher is tempted to smuggle in a pre-formed category (a pre-existing group, an individual intention, a passive object, a settled fact, a neutral description). The discipline is to refuse the smuggling and trace the actual associations through which groups form, actions are produced, objects participate, facts stabilize, and descriptions achieve credibility.

Origin

The book emerged from Latour's teaching at Sciences Po Paris and from two decades of ANT's institutional expansion. It was intended as a textbook — a consolidation of the research tradition for a new generation of scholars — and it succeeded in that role while also becoming Latour's most cited methodological statement.

Its reception was mixed within sociology. Critical sociologists, particularly those working in Marxist and Bourdieusian traditions, felt attacked; they accused Latour of abandoning the critical project in favor of a methodological positivism. Latour's reply was that the critical project could only succeed if it described reality accurately, and that the pre-formed categories it relied on were precisely what prevented accurate description. The disagreement has not been resolved.

Key Ideas

Society as explanandum, not explanans. 'The social' is what the sociologist is trying to explain, not what she invokes to explain individual behavior. Pre-forming the social is methodological cheating.

Five sources of uncertainty. Groups, actions, objects, facts, and accounts all need to be traced rather than assumed. Each is a site where categorical assumptions can smuggle in the pre-formed social that the analysis should be producing.

The difference between mediators and intermediaries. This is the book's most influential distinction. Most entities the sociologist encounters are mediators; the tradition treats them as intermediaries and thereby misses the actual work they do.

Trace the associations. The operation at the heart of the method. Describe the concrete chains of linkage, translation, and stabilization through which social assemblages come into being.

Plasma. Latour's term for the unformatted background against which formatted associations stand out. The plasma is the vast unorganized residue; the social is the localized organization that emerges from it.
