Anthropologist Roy Wagner defined invention as a way to defy the assumption that ordinary life is in most part determined. In this text we explore the notion of disability as an ordinary or conventional one, to contrast it with the notion of vital normativity proposed by Georges Canguilhem in the section II of the Normal and the pathological, which would be close to the notion of invention that Wagner develops. In this second approach the concept of vital normativity expresses the adaptative efforts of the individual, be it with or without disability. While in the former, collectivizing view of disability standardization contributes to the othering of disability, Roy Wagner’s approach of invention if applied to disability, would stress individual creativity. We defend that this differentiating view of disability, just as Canguilhem’s concept of vital normativity, opens new venues for disability emancipation beyond the realm of representation.
