Discussions of international and of gender justice both legitimately demand that principles of justice abstract from differences between cases and that judgments of justice respond to differences between them. Abstraction and sensitivity to context are often treated as incompatible: abstraction is taken to endorse idealized models of individual and state; sensitivity to human differences is identified with relativism. Neither identification is convincing; abstract principles do not entail uniform treatment; responsiveness to difference does not hinge on relativism. These points are used to criticize discussions of international and gender justice by liberals, communitarians and feminists. An alternative account of justice is sketched, which combines abstract principles with consideration of human differences in the application of principles. The case of poor women in impoverished economies – a hard case both for gender and for international justice – illustrates how universal, abstract principles of justice my not only permit but mandate differentiated application.
