 The argument for universal access sketched earlier specifically embraces Rawls’s fair equality of opportunity principle. It is worth remarking that the variations on this argument might retain steps 1–3 but modify the principle that is appealed to in 4, provided there is a reasonable connection between any substituted principle and the central observation in 3, that health affects the opportunity range open to people. For example, Sen has argued that the appropriate target of concerns about equality is a space of capabilities, thought of as functionings we can choose to exercise. A principle requiring us to protect the range of capabilities for people (either equally or to some sufficient level) would also provide a basis for keeping people functioning normally through universal access to interventions that reduce the health risks to them or that treat them for departures from normal functioning. Though Sen has not developed this account into a theory of justice that articulates a set of principles of justice, the central point here is that a concern to protect a space of functionings we can choose to exercise is equivalent to the focus of the earlier argument on protecting opportunities that it is reasonable for people to exercise (Daniels 2010).
