Polymorphic justice and the crisis of international order

The post-1945 international order is in crisis, spurring a wide-ranging debate about its future in a period of rapid global change. A critical dimension of this crisis has been neglected by existing perspectives, however. At multiple levels the post-1945 international order is being challenged by claims of justice. Diverse actors criticize the order for its economic inequalities, social hierarchies, institutional unfairness, intergenerational inequities, and historical and epistemic injustices. This article, which serves as an introduction to a special section on 'Injustice and the crisis of international order' seeks to map and explicate this polymorphic politics of global justice. We begin by reviewing past debates about justice and order in world politics, highlighting their narrow and over-stylized engagement with justice politics. To fill this gap, we develop a typology of contemporary justice claims, differentiating between recognitional, institutional, distributive, historical and epistemic, and intergenerational claims. Our goal is not only to distinguish these distinct kinds of justice claims, however. We argue that justice claims are also intersectional, multiscalar and multivocal, with significant implications for how the relationship between justice and order is managed in contemporary world politics.
