Theories of economic justice are characteristically based on abstract ethical concerns often unrelated to practical distributive results. Two decades ago, Rawls's theory of justice began as a reaction against the alleged ‘sacrifices’ condoned by utilitarian theory. One variant of this objection is that utilitarianism permits gross inequalities, severe deprivations of individual liberty, or even the enslavement of society's least well-off individuals. There are, however, more subtle forms of the objection. In Rawls, it is often waged without any claim that utilitarianism does in fact imply such gross deprivations in actual realworld circumstances. A second variant hinges, rather, on the milder claim that utilitarianism could condone such deprivations or sacrifices in some possible world—the objection being that utilitarianism improperly makes justice contingent, or uncertain, in this way. A third, still more abstract, variant would be that utilitarianism is flawed—not because of any practical distributive result, actual or hypothetical, but in theory—due to the way it treats individuals' interests, or the ‘concept of persons’ it presupposes.
