The incommensurability of experimental practices
an incommensurability of what? an incommensurability of a third type?
In the 1990s, authors such as Andrew Pickering and Ian Hacking, who worked on experimental practices and stressed the need for philosophy of science to take into account material and performative aspects of laboratory life, claimed to have discovered a new kind of incommensurability. Pickering talks about a "machinic incommensurability" while Hacking speaks of "literal incommensurability", but their target is approximately the same: an incommensurability related to a disjunction between the sets of instrumental devices, and correlatively the sets of measures obtained by their means, of two scientific practices. The paper discusses this proposal of Pickering and Hacking. It examines the situations that could correspond to the "machinic-literal" incommensurability. It elicits the possible implications of such situations from an epistemological point of view. And it analyses some difficulties which arise from the idea of an experimental incommensurability.
