 The social model of disability, which informs the Americans with Disabilities Act and kindred legislation, may appear to move disability away from health policy and toward civil rights. Yet movement in one direction does not preclude movement in the other. People with disabilities have significant health care needs, and their needs may depend to some extent upon their disabilities. For philosophers as well as policy makers, the challenge posed by the social model is to acknowledge the importance of health and health care for people with disabilities without assuming that all people with disabilities are unhealthy just because they are disabled, and without overemphasizing the correction or mitigation of impairments. This requires a careful examination of the relationship between health and disability. Do all disabilities result from, or in, a loss of health? Can a person with a disability be in good or even “perfect” health? To answer such questions, we need a serviceable theory, concept, or definition of health.
