Equality of capabilities: terminological innovation or a new approach to equal opportunity? - The principle of equality of capabilities developed by Sen and Nussbaum aims at providing a new conception of equality of opportunity, alternative to the major criteria

Recently, however, the innovative character of the Sen and Nussbaum principle has come under growing attack. Focusing on Sen’s version, the article first outlines the main features of the principle, and then goes on to single out and discuss some similarities with the other principles. The thesis is that, notwithstanding some similarities and various open problems, equality of capabilities represents an innovative distributive principle.
