Introduction
Is a global institutional order composed of sovereign states fit for cosmopolitan moral purpose? This question has lain near the heart of cosmopolitan thought at least since Kant’s interventions of the 1780s and 1790s. Kant seemed torn between supporting large-scale global institutional reforms—the creation of a world republic—and promoting a more modest transformation of states and their interrelations within a voluntary union. Likewise, in the more recent flowering of cosmopolitan thought, dating to the 1970s and intensifying from the immediate post–Cold War period, a persistent question has been whether states can be ascribed duties consistent with a cosmopolitan moral orientation, or whether, as Harold Laski memorably put it in 1925, state sovereignty is simply “incompatible with the interests of humanity.” Such institutional questions are central to this volume. This chapter introduces the major themes examined here and summarizes each author’s contribution.
