The Status of Anomalies in the Philosophy of Diderot

Annie Ibrahim (Lycée Chaptal / Collège International de Philosophie, Paris)

Abstract
Diderot’s reflections on monsters – not so much the perception of monstrosity or the relativity of our judgments on monstrous and ‘normal’ form, but rather the occurrence of ‘sports’ or ‘freaks of nature’ as a part of biological functioning overall – are in good part a reflection of his ‘Lucretianism’, that is, his vision of a universe in constant transformation, in which non-viable forms are regularly produced but just as quickly, removed. Two paradoxes emerge as a result of this vision: first, that Diderot sees monsters everywhere but also strips the notion of its normative content; second, that we are tempted to understand it as a ‘proto-transformism’, or alternately, as a proto-teratology. I suggest that this approach is misguided, because Diderot’s materialism never departs from a fascination with fictions: his ‘proto-scientific’ ideas are inextricable from the ‘dream’ format in which they are presented.
