  Rawls suggests that the conception of resources to be deployed in a resourcist ideal of equality is primary social goods. These are defined as distributable goods that a rational person prefers to have more rather than less of, whatever else she wants. (A variant conception identifies them as goods that any rational person would want who gives priority to her interests in (1) cooperating with others on fair terms and (2) selecting and if need be revising a conception of the good and a set of life aims along with pursuing the conception and the aims.) On this approach it is not so far clear how to measure a person's holding of social primary goods overall if there are various primary goods and one has different amounts of the different kinds. The primary goods approach has yet to be developed in detail. Rawls has suggested that the scope of this problem of devising an index of primary goods is lessened by giving some primary goods, the basic liberties, priority over the rest. For the remainder, Rawls suggests that the relative weight of primary goods can be set by considering what people (regarded as free and equal citizens) need. (See Rawls 2001, section 17.)
