Tremain calls for a genealogical method of studying disability: one that traces the historical conditions and discursive shifts that produced it as a category. Genealogy, for Tremain, is a tool of resistance—it destabilizes taken-for-granted truths and exposes how they serve existing power structures. Through this approach, disability studies can uncover new ways of thinking about identity, justice, and embodiment that are not bound by ableist norms.
