Abstract
Economists have moved away from thinking of development in terms of growth of per capita GNP. The most influential alternative conception of development ‐ due to Amartya Sen ‐ involves judging the quality of life in terms of capabilities and viewing development as a ‘capability expansion’. This article argues that Sen's approach is an inadequate account of development. It is further argued that other versions of the approach ‐ involving the work of Nussbaum and Frankfurt ‐ also fail. The most promising foundation for an account of human development derives from James Griffin's recent writings on well‐being.
