In this paper, we use a diffractive reading developed by feminist philosopher and quantum physicist Karen Barad, as part of a response-able methodology, in order to consider the claim made by Serge Hein in his paper 'The New Materialism in Qualitative Inquiry: How Compatible Are the Philosophies of Barad and Deleuze?' (2016) that the philosophies of Barad and Deleuze and Guattari are incommensurable. Our point of departure is from a stance which is quite different from that of Hein's -- we propose that it is indeed productive to put the work of Barad into conversation with that of Deleuze. As an alternative to critique used by Hein to engage with the work of Barad and Deleuze, we consider how a response-able and diffractive reading of notions of critique could provide a more affirmative and productive way of reading academic texts, including those by Barad and Deleuze.
