For Kant, the contents of cosmopolitan law are to be ‘limited’ to non-citizens' subjective rights to hospitality. Although hospitality yields universal and far-reaching communicative rights, its limits may seem overly restrictive at first. I argue that this narrow focus is intended to fend off justifications for colonial occupation that could otherwise draw support from Kant's own doctrine of private law. Kantian hospitality is further limited in that it does not cover all forms of communicative exchange. As can be shown from (...) his endorsement of China's and Japan's protectionist policies, Kant is not averse to limiting cosmopolitan citizens' commercial speech. In conclusion, I discuss rivalling interpretations of Kant's justification of hospitality. I argue that this justification cannot rest exclusively on the innate human right to freedom, but must draw on facts about the world as well. (shrink)
