Capabilities vs. Opportunities for Well-being

Abstract

Amartya Sen and Martha Nussbaum have argued that justice is concerned, at least in part, with the distribution of capabilities (opportunities to function). Richard Arneson, G.A. Cohen, and John Roemer have argued that justice is concerned with something like the distribution of opportunities for well-being. I argue that, although some versions of the capability view are incompatible with some versions of the opportunity for well-being view, the most plausible version of the capability view is identical to a slight generalization of the opportunity for well-being view.
