A central question for assessing the merits of Amartya Sen's capability approach as a potential answer to the “distribution of what”? question concerns the exact role and nature of freedom in that approach. Sen holds that a person's capability identifies that person's effective freedom to achieve valuable states of beings and doings, or functionings, and that freedom so understood, rather than achieved functionings themselves, is the primary evaluative space. Sen's emphasis on freedom has been criticised by G. A. Cohen, according to whom the capability approach either uses too expansive a definition of freedom or rests on an implausibly active, indeed “athletic,” view of well-being. This paper defends the capability approach from this criticism. It argues that we can view the capability approach to be underpinned by an account of well-being which takes the endorsement of valuable functionings as constitutive of well-being, and by a particular view of the way in which endorsement relates to force and choice.
