This chapter outlines the basic elements that underwrite Kant's cosmopolitanism. In doing so, the chapter looks at the moral principles behind Kant's cosmopolitanism and the problem of Kant's cosmopolitan teleology, and develops a brief overview of Kant's more coherent principles of cosmopolitan law. It makes a connection between Kant's critical philosophy and the moral foundations of his cosmopolitanism. By framing Kant's overall cosmopolitan vision, this chapter further explores Kant's theory of history and suggests that it is based on a problematic teleology. The chapter concludes by linking the various aspects of Kant's cosmopolitanism into a single coherent narrative that provides a basis for future developments.
