Purification

In the AI Story

In We Have Never Been Modern (1991), Latour argued that the modernity that Western societies believe themselves to inhabit has never actually existed. What actually exists is a constant proliferation of hybrids — entities that are simultaneously natural and social, technical and political — paired with a rhetorical operation that insists hybrids do not exist, that each hybrid is 'really' one pure thing or the other. The constitution is the tacit agreement never to acknowledge that the two operations are happening simultaneously: the world is filled with hybrids, and the official accounts of the world deny that hybrids exist.

The consequence is systematic misrecognition. Scientists speak for Nature — pure, objective, non-social — but scientific laboratories are saturated with social negotiation, funding politics, and cultural assumption. Politicians speak for Society — the human realm of values and choice — but political life is constituted by material infrastructures, technical systems, and non-human participants whose characteristics shape what is possible. Each side of the divide accuses the other of contamination while denying its own. The constitution is stable because the denials are symmetrical.

AI cannot be accommodated within this architecture. It is not merely a technical artifact that society must regulate. It is not merely a social institution dressed in mathematical clothing. It is the paradigmatic hybrid: its capabilities are produced by engineering decisions that encode cultural biases; its optimization targets are value choices masquerading as technical parameters; its effects redistribute capability and restructure labor markets in ways that are irreducibly political. Governing AI as a matter of pure technology is absurd. Governing it as a matter of pure politics — regulating effects without understanding mechanisms — is incompetent. What is required is a governance architecture adequate to the hybrid reality, and no such architecture exists.

The concept has direct implications for the myth of the human agent. The Orange Pill's narrative places Segal at the center of the thirty-day sprint — his vision, his team's execution, the human drama that produced Napster Station. This is purification in action: separating the human contributions from the non-human contributions, arranging them into a hierarchy in which the human is the source of agency and everything else is instrumental. The purification is not innocent. It obscures the actual distribution of agency in the network, which is neither purely human nor purely machine but hybrid, and it thereby obstructs the governance that hybrid networks require.

Origin

The concept was elaborated in We Have Never Been Modern (1991), Latour's most influential general-theoretical book, where it anchors his analysis of what he called the 'modern constitution'. The book drew on two decades of laboratory ethnography and political theory to argue that the modern West's self-understanding as having overcome pre-modern hybridity was itself a myth — maintained precisely by the rhetorical work of purification that insisted hybrids did not exist.

The book was received controversially. Scientists objected that Latour was dissolving the distinction between genuine scientific knowledge and arbitrary social construction. Critical theorists objected that he was blunting the political weapons that the nature/society distinction had provided for challenging capitalist ideology. Latour's defense — that he was describing the actual operation of modern thought rather than endorsing it — has had to be repeated in every subsequent decade.

Key Ideas

Two operations, one denial. Modernity simultaneously proliferates hybrids and denies they exist. The constitution is stable because the denial is systematic.

Specialized authorities. Scientists speak for Nature; politicians speak for Society. Each domain has its official spokespersons, and the boundary is policed by both sides.

Hybrids that cannot be accommodated. Certain phenomena — climate change, GMOs, pandemics, AI — refuse purification so insistently that they expose the constitution as fiction.

Governance consequence. Regulatory frameworks built on the purified categories cannot govern hybrid entities. The EU AI Act addresses technology; democratic deliberation addresses society; but AI exists in the space between.

The task of reconstruction. Recognizing purification is only the first step. The harder work is building a governance architecture — what Latour called a parliament — capable of deliberating about hybrids without pretending they are pure of one side or the other.

Debates & Critiques

The most sustained objection, from scientific realists like Alan Sokal, charges that purification-critique is a generalized skepticism that dissolves the distinction between well-established scientific knowledge and ideological construction, thereby licensing denial of climate change, evolution, and vaccine efficacy. Latour himself became alarmed by exactly this uptake and spent much of his later career — notably in the matters of concern framework — clarifying that critique of purification was not critique of scientific factuality. The critique was aimed at the rhetorical operation that treats all scientific claims as purely natural and all political claims as purely social, not at the specific procedures through which robust scientific claims are produced.
