 Part 2 will examine philosophical writing on health and disease. It will review different definitions of health and their implications for the question of whether it is necessarily unhealthy to be disabled. It will consider the few attempts that have been made to distinguish disability from disease. It will also note a tension for disability scholars in making the distinction between disease and disability: although that distinction provides a basis for separating the medical from the socially constructed aspects of disability, it can also oversimplify the experience of people with disabilities.
