There Is No List of Capabilities
In his review of Amartya Sen's "Commodities and Capabilities," Robert Sugden of the University of East Anglia noted what he thought was a serious lack of insight in Sen's approach. "This is an important idea, but Sen has disappointingly little to say about how these sets are to be valued; he makes a few suggestions but only to show how unsatisfactory they are." In the point of view of Sugden, there is a need for a ranking of capabilities because in order to judge whether or not someone is living a full life, we need to know what the scale is that judges that happy life.
