focus on ‘refined functionings’ (being the combination of functionings<br />

<strong>and</strong> capabilities).<br />

A third issue which needs to be solved if one hopes to develop a<br />

capability theory of justice is to decide <strong>and</strong> justify which capabilities<br />

matter the most. <strong>The</strong>re are at least two ways of answering this question:<br />

either through procedural approaches, such as using criteria from<br />

which the relevant capabilities are derived, or by defending a specific<br />

list of capabilities. This selection of relevant capabilities for the purpose<br />

of justice can be done at the level of ideal theory (without taking issues<br />

of practical feasibility <strong>and</strong> implementation into account), at the level of<br />

abstract principles (Anderson 1999; Nussbaum 2006b; Claassen 2016) or<br />

at an applied theoretical level, which is useful for practical assessments<br />

of unjust inequalities (e.g. Robeyns 2003; Wolff <strong>and</strong> De-Shalit 2007).<br />

Fourth, a capability theory of justice may need to engage in a<br />

comparison with other ‘metrics of justice’. In the literature on social<br />

justice there are several terms used to indicate what precisely we are<br />

assessing or measuring: the metric of advantage, the currency of justice,<br />

or the informational basis for the interpersonal comparisons for the<br />

purpose of justice. Within theories of justice, the main arguments are with<br />

Rawlsian resourcists 24 <strong>and</strong> with defenders of Dworkinian resourcism. 25<br />

Other possible metrics are basic needs or the many different types of<br />

subjective welfare or preference satisfaction. A full capability theory of<br />

justice would need to show why it serves better as a metric of justice<br />

than these other metrics.<br />

Fifth, a capability theory of justice needs to take a position on the<br />

“distributive rule” (Anderson 2010, 81) that it will endorse: will it argue<br />

for plain equality, or for sufficiency, or for prioritarianism, or for some<br />

other (mixed) distributive rule? Both Martha Nussbaum’s <strong>and</strong> Elizabeth<br />

Anderson’s theories are sufficiency accounts, but from this it does not<br />

follow, as one sometimes reads in the secondary literature, that the<br />

capability approach entails a sufficiency rule. Sen may have given the<br />

(wrong) impression of defending straight equality as a distributive rule,<br />

24 An analysis of this comparison between social primary goods <strong>and</strong> capabilities was<br />

made by the various contributions to the volume edited by Brighouse <strong>and</strong> Robeyns<br />

(2010).<br />

25 For comparisons of the capability view with Dworkin’s egalitarian theory, see Sen<br />

(1984b, 321–23, 2009c, 264–68); Dworkin (2000, 299–303); Williams (2002); Browne<br />

<strong>and</strong> Stears (2005); Kaufman (2006); Pierik <strong>and</strong> Robeyns (2007).
