 Approaches based on equality of opportunity can be read as revisions of both welfarism and resourcism. Ranged against welfarism and designed to avoid its pitfalls, they incorporate the powerful ideas of choice and responsibility into various, improved forms of egalitarianism. Such approaches are meant to equalize outcomes resulting from causes beyond a person’s control (i.e., beyond circumstances or endowment), but to allow differential outcomes that result from autonomous choice or ambition. But the approaches are also aimed at maintaining the insight that individual preferences have to count, as the sole basis for a necessary linkage back to the individual perspective: otherwise, there is an overlooking of the person’s value. In Arneson’s (1989, 1990) concept of equal opportunity for welfare, the preferences determining the measure of individual well-being are meant to be conceived hypothetically – i.e., a person would decide on them after a process of ideal reflection. In order to correspond to the morally central vantage of personal responsibility, what should be equalized are not enlightened preferences themselves, but rather real opportunities to achieve or receive a good, to the extent that it is aspired to. G.A. Cohen’s (1989, p. 916 f.) broader conception of equality of access to advantage attempts to integrate the perspectives of welfare equality and resource equality through the overriding concept of advantage. For Cohen, there are two grounds for egalitarian compensation. Egalitarians will be moved to furnish a paralyzed person with a compensatory wheelchair independently of the person’s welfare level. This egalitarian response to disability overrides equality of (opportunity to) welfare. Egalitarians also favor compensation for phenomena such as pain, independent of any loss of capacity – for instance by paying for expensive medicine. But, Cohen claims, any justification for such compensation has to invoke the idea of equality of opportunity to welfare. He thus views both aspects, resources and welfare, as necessary and irreducible. Much of Roemer’s (1998) more technical argument is devoted to constructing the scale to calibrate the extent to which something is the result of circumstances. An incurred adverse consequence is the result of circumstances, not choice, precisely to the extent that it is a consequence that persons of one or another specific type can be expected to incur.
