 A Foucauldian approach follows through on efforts in critical disability theory to challenge the distinction between impairment and disability. Tremain argues that the social model, embedded in traditional disability studies and in the thinking of U.K. activists, fails because it strongly distinguishes between impairment and disability (2005: 9). For Tremain, impairment is not natural, value-neutral, and objective but rather is “historically specific and performative” (2017: 115, cf. 2005: 11). Along these lines, Tremain works to undermine, defamiliarize, and denaturalize terminology like “people with disabilities”, hierarchies of “severity” among impairments, the terminology of impairment itself, and type or kind distinctions among disabilities (e.g., physical or intellectual, among other similar terms) (2017). For her, impairment, like disability, is the product of power relations. Just as Judith Butler claims that sex is performatively constituted through gender, Tremain leverages Foucault to make the same claim about the relationship between disability and impairment (2017: 115, cf. Tremain 2001). She writes, “impairment has been disability—or rather, an element of the apparatus of disability—all along” (2017: 93). Indeed, according to Tremain, we should not be surprised that impairment itself is historical as “the shifting limits and borders of the classification of impairment demonstrate its historicity and cultural specificity” (2017: 93).
