 The differences among standard accounts of well-being are particularly significant in thinking about the well-being of people with severe cognitive impairments. We believe that a separate discussion of this topic is warranted, but not because cognitive impairments are in a class by themselves. As we have noted, there are great differences among all types of impairments. Cognitive impairments, however, have until recently received relatively little attention in philosophy, and we give them special emphasis as a corrective.
