Abstract

I argue that, if it is thought desirable to avoid the collapse of disability into generic social disadvantage, it is necessary to draw a distinction between impairment (a bodily configuration) and disability (the way in which the environment prevents someone with an impairment from undertaking certain kinds of activities), as in social models of disability. I show how to draw such a distinction by utilizing a distinction between intrinsic and extrinsic properties. I argue further that, using this distinction, it is possible to define ‘impairment’ in ways that do not appeal to notions of the normal, and to define ‘disability’ in terms of ‘impairment.’
