Harlan Hahn's review of Deborah A. Stone's The Disabled State (November/December 1985) does this book and its potential readers a disservice. Admitting its impressive scholarship, Hahn puts the book down on the ground that it does not comport with his values. His view is that disability is primarily a product of a disabling environment created by government policy. .; he wants Stone to admit that unemployment and other problems confronting disabled citizens are primarily created by discriminatory practices in an inhospitable environment. . Yet it is precisely Stone's understanding that, except at the extremes, disability is not something out there in nature, obvious and agreed upon by everyone, but rather a variable product of change in social definitions that makes her contribution a seminal one. Portraying people with whom one disagrees as advocates of inflicting serious harm is not likely to increase understanding or improve public policy. Aaron Wildavsky University of California, Berkeley
