Abstract
The paper develops a theory of human rights under three main headings: that ways of acting or of being treated require effective normative justification, that they must have authoritative political endorsement or acknowledgement, and that they must be maintained by conforming conduct and, where need be, by governmental enforcement. The paper, then, applies this notion of human rights to two main cases: as constitutional rights within individual states (the case primarily contemplated within the UN's Universal Declaration), and as international human rights maintained by confederations of states or by looser international coalitions.
