Bruno Latour and Steve Woolgar made use of Gaston Bachelard’s concept of phenomenotechnique in Laboratory Life. Stating that this use of a Bachelardian concept contrasts with the sharp criticism Latour made of Bachelard in his later work, I consider whether it belongs to an early Bachelardian stage of Latour’s study of science or whether Latour and Woolgar made, from the beginning, an original and anti-Bachelardian use of the concept of phenomenotechnique. I address this question by offering two symmetrical readings of (...) Laboratory Life: one reading adopts a Bachelardian perspective, in which Latour and Woolgar’s ethnological and sociological investigation appears as an empirical corroboration of Bachelard’s epistemological theses, whereas the other reading insists on the way in which Latour and Woolgar depart from Bachelard, as the sociological study of the way in which power relations shape scientific practice challenges the latter’s rationalist convictions. Although I contrast Bachelard’s epistemological use of the concept of phenomenotechnique with Latour and Woolgar’s sociological one, I wonder in the conclusion whether these approaches to science may be regarded as complements rather than antagonists and find in Pierre Bourdieu’s theses on the specificity of the scientific field resources to combine them.
