Disability, "being unhealthy," and rights to health

Often advocates for persons with disabilities strongly object to the claim that disability essentially involves a decrement in health. Yet, it is a mystery why anyone with an impairment would ever deny, or feel uncomfortable being told that, their impairment is at bottom a health problem. In this paper, I investigate the conceptual linkages between health and disability, relying on robust conceptualizations of both notions, and conclude it makes no conceptual sense to insist that a person can be seriously impaired yet still be, or become, "perfectly healthy." But that cannot be the end of it since this kind of error is commonly made, and I try to tease out the reason why not only disability advocates but agencies like the WHO and the CDC fall victim to it. I conclude by conceding that there are indeed sound political reasons for being cautious about the alignment of disability and ill-health, but suggest that the price we pay in conceptual confusion may be too high to allow those reasons to dictate policy.
