Book excerpt: Disability Politics and Theory, a historical exploration of the concept of disability, covers the late nineteenth century to the present, introducing the main models of disability theory and politics: eugenics, medicalization, rehabilitation, charity, rights and social and disability justice. A.J. Withers examines when, how and why new categories of disability are created and describes how capitalism benefits from and enforces disabled people’s oppression. Critiquing the currently dominant social model of disability, this book offers an alternative. The radical framework Withers puts forward draws from schools of radical thought, particularly feminism and critical race theory, to emphasize the role of interlocking oppressions in the marginalization of disabled people and the importance of addressing disability both independently and in conjunction with other oppressions. Intertwining theoretical and historical analysis with personal experience, this book is a poignant portrayal of disabled people in Canada and the U.S. — and a call for social and economic justice. This revised and expanded edition includes a new chapter on the rehabilitation model, expands the discussion of eugenics, and adds the context of the growth of the disability justice movement, Black Lives Matter, calls for defunding the police, decolonial and Indigenous land protection struggles, and the COVID-19 pandemic.
