'In this careful and insightful book, Pauline Kleingeld reconstructs Kant's cosmopolitanism, placing him in dialogue with historical contemporaries (including Christoph Wieland, Anacharsis Cloots, Georg Forster, Dietrich Hegewisch, and Novalis), and with several present-day thinkers (John Rawls, Jürgen Habermas, and Thomas Pogge). The result is an extremely clear and engaging work, one that manages to add something both to our understanding of Kant and to our understanding of what a 'cosmopolitan' political theory should look like today … This book deserves a wide audience for its fine reconstruction of Kant's views on international justice.'
