Kantian cosmopolitanism beyond 'perpetual peace': Commercium, critique, and the cosmopolitan problematic

Most contemporary attempts to draw inspiration from Kant's cosmopolitan project focus exclusively on the prescriptive recommendations he makes in his article, 'On Perpetual Peace'. In this essay, I argue that there is more to his cosmopolitan point of view than his normative agenda. Kant has a unique and interesting way of problematizing the way individuals and peoples relate to one another on the stage of world history, based on a notion that human beings who share the earth in common 'originally' constitute a 'commercium' of thoroughgoing interaction. By unpacking this concept of 'commercium', we can uncover in Kant a more critical perspective on world history that sets up the cosmopolitan as a specific kind of historical-political challenge. I will show that we can distinguish this level of problematization from the prescriptive level at which Kant formulates his familiar recommendations in 'Perpetual Peace'. I will further show how his particular way of framing the cosmopolitan problematic can be expanded and expatiated upon to develop a more critical, reflexive, and open-ended conception of cosmopolitan thinking.
