What moral work can Nussbaum's account of human dignity do in the context of dementia care?

Appeals to the dignity of people with dementia are widespread in the current literature on dementia care. One influential account of dignity in the wider philosophical and bioethical literature that has remained underexplored in the context of dementia care is that of Martha Nussbaum. This paper critically examines Nussbaum's account of dignity and aims to determine what moral guidance this account can offer for the provision of care to people with dementia. To that end, first, I identify four possible objections to appeals to dignity in dementia care. These objections are (1) redundancy of the dignity talk, (2) exclusionary implications, (3) reliance on (suspect forms of) speciesism and (4) unclear practical implications. Then, I discuss whether, and to what extent, Nussbaum's account of dignity can overcome these objections. I argue that Nussbaum's account, in its original form, struggles to overcome the problem of exclusionary implications and consequently the problem of unclear practical implications. I argue for a modified version of Nussbaum's account of dignity. I demonstrate that this modified version can better overcome all of the four objections, and it provides relatively clearer moral guidance for the provision of care to people with dementia. The modified version of Nussbaum's account is predicated on a novel dementia-specific model of flourishing, which draws on Kitwood and Bredin's empirically informed list of indicators of well-being for people with dementia.
