 Before describing these developments, it is useful to distinguish two types of distributive theories. Modern social contract theories, notably Rawls’ (1971), seek to determine the fair terms of social cooperation to which individuals (generally with limited knowledge of their own situations) would agree; they argue that certain distributive principles would be among those terms (Rawls’ “difference principle” may be the most familiar). Rawlsian theories are procedural in one sense: they regard any distribution as just if and only if it is consistent with the distributive principles that would be chosen by those individuals. Disability-oriented criticism of these theories has focused on their assumptions about the individuals who are eligible to make a hypothetical contract or participate in the cooperative scheme it establishes. Critics have argued for the eligibility of people with disabilities or their representatives to participate in the contract-making processes and resulting cooperative scheme more than about the validity of the principles or rules yielded by that process (Richardson 2006; Silvers and Francis 2005; Stark 2007). The second type of theory is primarily interested in outcomes; in the kind of end state a just society should strive for: either equality on some outcome metric or the reduction of certain kinds of inequality. Here, disability-informed criticism has favored outcome metrics that take account of the social contribution to disability-related disadvantage, and standards for just distributions that are oriented toward disrespectful inequalities (Anderson 1999; Nussbaum 2006a; Wolff 2009b).
