 If advantages or disadvantages that are due to arbitrary and unearned differences are unfair, this holds for social circumstances as well as natural endowments. The reasons favoring an exclusion of features like skin-color, size, sex, and place of origin as primarily discriminative apply equally to other natural human qualities, like intelligence, appearance, physical strength, and so forth. The kind and the extent of one’s natural abilities are due to a lottery of nature; considered from a moral standpoint, their distribution is purely arbitrary (Rawls, 1971, § 48). To sum up: natural and social endowment must not count, and personal intentions and voluntary decisions should count. Thus, a given social order is just when it equalizes as much as possible, and in a normatively tenable way, all personal disadvantages for which an individual is not responsible, and accords individuals the capacity to bear the consequences of their decisions and actions, as befits their capacity for autonomy.
