 Further, critical disability theory contributes to philosophy in a broad range of ways. Critical disability theory challenges the marginalization of the study of disability and its ghettoization within bioethics (and its circumscription, thereby, to the medical model) (Tremain 2017). As Tremain argues, disability matters to core debates in philosophy. Specifically, philosophy of disability, as one form critical disability theory can take, contributes to central philosophical puzzles, including debates over relativism, materialism, realism, and determinism (2015).
