Is there a nonsocial component to the concept of disability? Silvers says that there used to be an idea of “bad biology” that was used against people with disabilities. What is the biological difference between a disease and a disability? John goes over three responses to disability that he has heard in the past: view it as a deficiency, view it as ennobling, and view it as a mere difference. Where does reasonable accommodation end and social hijacking begin? Silvers starts with people who have anomalous biology. Society may have to change certain practices to accommodate disabled people. How much accommodation is reasonable? Should society change to accommodate all disabled people?

Is it fair to compare blindness to deafness or obesity? Each of those is very different from the others. Are learning disabilities in the same ballpark as, say, deafness? Who should bear the financial burden for accommodating disabled people? Silvers says that disabled people must first show that they count as disabled then show that their disability needs accommodation.
