This paper examines the contributions that the international human rights community can make to the definition and framing of a practically effective global ethic, especially in light of ongoing concerns about social and economic justice, environmental issues, and systematic abuses of vulnerable populations. The principal argument is that the human rights movement in all of its dimensions (moral, legal, political) provides the pivotal foundation for a practicable global ethic now and for the foreseeable future. Evidence for the truth of this claim is discerned in the movement's contemporary efforts to intersect explicitly with other areas of international law and politics. Examples adduced include developments with respect to the rights of indigenous peoples, decision making about the environment, and transitional justice.
