Fifth, a capability theory of justice needs to take a position on the ‘distributive rule’ (Anderson 2010: 81) that it will endorse: will it argue for plain equality, or for sufficiency, or for prioritarianism, or for some other (mixed) distributive rule? Both Nussbaum’s (2006) and Andersons’s (1999; 2010) theories are sufficiency accounts, but from this it does not follow, as one sometimes reads in the secondary literature, that the capability approach entails a sufficiency rule. Sen may have given the (wrong) impression of defending straight equality as a distributive rule, by asking the question ‘Equality of what?’ (Sen 1979a), though a careful reading shows that he was merely asking the question ‘If we want to be defending equality of something, then what would that be?’ In fact, Sen has remained uncommitted to one single distributive rule, which probably can be explained by the fact that he is averse of building a well-defined theory of justice but rather prefers to investigate how real-life unjust situations can be turned into more just situations, even if perfect justice is unattainable (Sen 2009). The capability approach clearly plays a role in Sen’s work on justice, since when assessing a situation he will investigate inequalities in people’s capabilities and analyze the processes that led to those inequalities.
