Abstract
This chapter discusses the normative and theoretical foundations of human rights. More specifically, it examines the theoretical basis for the normative ideas advanced by those who use the language of human rights for an ethical critique of international politics and policy. The chapter first traces the origins of the language of rights before discussing cultural relativism and imperialism, both of which challenge the United Nations Universal Declaration of Human Rights’ claim to have universal application. It then considers the negative/positive distinction as a way of thinking about the differences between liberty and welfare rights. It also explores group rights, along with the philosophical and political history of the idea of human rights. Finally, it explains how the human rights agenda is deeply political, showing that it privileges a certain set of normative commitments that its proponents hope will become, in time, the ethical constitution of the international system.
