 This response, however, suggests two final sources of difference, both of which involve what we might call “welfare security”. Even if people with a single major disability can live as well as people without one, 1) it requires more effort or luck for them to do so, and 2) they are at greater risk of lacking the means to do so. The first claim is that the fewer means there are to achieve a particular good like rich aesthetic experience, the more difficult it may be to achieve it. An individual who can meet his aesthetic quota, so to speak, with sunsets or symphonies, doesn’t have to work as hard or need as aesthetically rich an environment as one who can meet his quota only with symphonies. The second claim is that people with single disabilities are at greater risk than people without any disabilities of losing the means to achieve various goods, since they have a smaller surplus or reserve. The plausibility of these claims depends on a myriad of unresolved issues: Is there an irreducible plurality of objective goods and if so, how they are individuated? Are there a limited number of means for attaining those goods? If it requires greater effort to attain a particular good with fewer functions, does that additional effort itself enhance or reduce well-being?
