 The debate between the medical and social model about the source of the disadvantages disabled people experience has dominated academic discourse about disability since the 1970s. More recently, however, disability activists and disabled scholars have questioned the apparent shared assumption of both models, that disability is fundamentally a matter of disadvantage, exclusion, or functional limitation. This to take a (partly) different view on what an account of disability should explain; a view consistent in principle with either a more medical or more social view of what does the explaining. The affirmative model of disability and impairment, as articulated by John Swain and Sally French (2000), holds that disability is not in the first instance a problem—not simply or solely a “personal tragedy”, and implicitly, not simply or solely a social injustice either. Rather, disability is a different way of living in and experiencing the world, one not characterized by its disadvantages any more than its advantages.
