Apparatus and its Uses: ‘Ecologising' Diffraction As A Materialist-Epistemological Practice

Abstract

This paper addresses the problem of how to 'do' theory without implying “that theorizing is outside the world” (Barad & Gandorfer, 2021, p. 16) by elaborating a particular, ecological use of the apparatus. Tracing Foucault’s use of the dispositif (Foucault, [1977] 1980, p. 194), I argue that his key invention is identifying the generative capacity of the apparatus in terms of its constraints, which coincide with its situatedness as part of the world. By diffractively reading this invention through Barad’s posthumanist use of the apparatus, their agential realist practice of diffraction is re-iterated as a specifically 'ecologising' technique. Rather than following Barad in grounding this technique ontologically, Foucault’s “author-function” (Foucault 1969) leads me to ground such theorising an ongoing, materialist-epistemological engagement with the environment.
