Drawing on the built environment concept of “inclusive design” and its emphasis on creating accessible environments for all persons regardless of ability, I suggest that a central task for feminist disability theory is to redesign foundational philosophical concepts to present opportunities rather than barriers to inclusion for people with disability. Accounts of autonomy within liberal philosophy stress self-determination and the dignity of all individual persons, but have excluded people with intellectual disability from moral and political theories by denying their capacity (...) for individual autonomy, seen as a chief marker of moral personhood. This paper modifies and extends feminist theories of relational autonomy by arguing for the need to view autonomy as a feature of persons that is manifested only through relations of support, advocacy, and enablement. An “inclusively designed,” relational account negotiates the tensions encountered in attempts to apply autonomy to people with high support needs, and politicizes the concept as an advocacy tool for people with intellectual disability and their allies.
