Science and Poetry as Complementary Vocabularies
Science and poetry describe different dimensions of the same phenomena using different vocabularies, and neither vocabulary is reducible to the other. The physicist can describe a sunset as electromagnetic radiation scattered at specific wavelengths. The poet can describe the same sunset as a transformation of meaning, an emblem of ending, an invitation to reflection. Both descriptions correspond to something real. Eliminating either produces an understanding that is accurate in what it includes and impoverished in what it leaves out. Midgley argued that this complementarity is not a diplomatic compromise between warring camps but a structural feature of reality itself — and that the AI discourse's monopolisation by a single vocabulary (the computational) is producing exactly the impoverishment her framework predicts.
In the AI Story
The argument is directed against a specific intellectual formation Midgley called scientism: the view that scientific description is the only legitimate form of description and that everything real must ultimately be expressible in scientific terms. Against this, Midgley insisted that reality has multiple dimensions, and no single vocabulary can capture all of them. The vocabulary of physics is superb for describing mechanisms. It is useless for describing meaning. The vocabulary of poetry is superb for describing meaning. It is useless for describing mechanisms.
The relevance to AI is immediate. The AI discourse operates almost exclusively in the computational vocabulary — the vocabulary of inputs, outputs, parameters, capabilities, benchmarks, scaling laws. This vocabulary is superb for describing what the machines do. It is incapable of describing what the machines mean to the people who use them, what the experience of working with them is like, what gets lost when human work is reshaped around them. These other dimensions do not disappear because the vocabulary cannot reach them. They become invisible — present in experience but absent from the discussion.
Midgley's most precise formulation of the complementarity came in Science and Poetry (2001): 'Certain ways of thinking that proved immensely successful in the early development of the physical sciences have been idealised, stereotyped and treated as the only possible forms for rational thought across the whole range of our knowledge.' This sentence, read in 2026, describes the AI discourse with uncanny precision. The way of thinking that proved successful in building large language models has been idealised, stereotyped, and treated as the only possible form for intelligence itself.
The methodological consequence is that any adequate response to the AI moment must be multi-vocabulary. The Orange Pill's willingness to move between data, confession, economic analysis, and existential metaphor is not a weakness of method — it is an honesty about the subject. Each vocabulary captures a dimension. None exhausts the phenomenon. The integration is harder than the separation, but the integration is closer to the truth.
Origin
The complementarity argument runs through Midgley's work from Beast and Man onward but receives its fullest articulation in Science and Poetry (Routledge, 2001). The book's title deliberately invoked the ancient quarrel between the two — and proposed its dissolution through the recognition that the quarrel rests on a false presupposition: that there can be only one legitimate way of describing reality.
Key Ideas
Multiple dimensions, multiple vocabularies. Reality has dimensions that require different descriptive tools; no single vocabulary is adequate to all of them.
Not a compromise. Complementarity is not a political settlement between physicists and poets — it is a structural feature of the relationship between knowledge and its subjects.
Invisibility of the uncaptured. What a vocabulary cannot describe does not disappear — it becomes invisible to the users of that vocabulary.
Multi-register honesty. Adequate response to complex phenomena requires the willingness to shift registers — the opposite of the disciplinary rigor that insists on a single tongue.
