"Like strong cosmopolitans, Mandle endorses a universalistic conception of human rights. Against them, he defends the widely assumed moralsignificance of national borders - appealing not to common language, culture, history, or sentiments, but to shared citizenship in a state. This is a clear and promising attempt to explain and develop some deeply held and widely shared intuitions about justice."Thomas Pogge, Professorial Research Fellow, Centre for Applied Philosophy and Public Ethics, The Australian National University"A compelling argument for an internationalist position that recognizes the independence of nations and the fundamental significance of social and political relations, yet which imposes a vigorous duty to assist disadvantagedpeoples to enable all to exercise a broad range of human rights. Mandle sympathetically responds to cosmopolitans’ concerns without surrendering the field to cosmopolitan critics of the priority of social and political justice."
