Reconciling legal positivism and human rights: Hans Kelsen's argument from relativism

This article examines the conceptual relationship between legal positivism and human rights, challenging the common idea that the two are in tension or that there exists, at most, a contingent relationship between them, whereby legal positivists can only recognize the normative validity of human rights if they happen to be inscribed in positive law. To do this, I focus on the thought and writings of one of the “founding fathers” of modern legal positivism: the Austrian legal theorist and political philosopher Hans Kelsen. In the first part, I show that Kelsen's conception of legal positivism is inextricably tied to — and, indeed, logically stems from — his moral relativism. In the second, I show that this form of relativism is also the philosophical foundation for Kelsen's commitment to democracy and human rights. Finally, in the third part, I examine the specific conception of human rights that results from this relativistic foundation, contrasting it with the “natural law” version that legal positivism excludes.
