Although Nussbaum’s “Capabilities Approach” clearly expresses a commitment to objectivity, this article argues that this commitment is rather ambiguous due to the conception of public reason it endorses.

As a result, the CA jeopardizes the substantive aim it has set itself: to provide an objective justification for public choices regarding human capabilities and their specifications.
