The “principle of outer freedom” is the justificatory premise in the argument which leads to the establishment of cosmopolitan right. Since, however, exercising our external freedom means that sooner or later, under certain circumstances, we will need to cross boundaries and come into contact with fellow human beings fromother lands and cultures, we need to recognize the following: first, that the earth’s surfacewill be apportioned into the territory of individual republics; second, that conditions of right regulating intra- aswell as interrepublican transactions arenecessary; and finally thatamongthose conditions are those pertaining to the rights of hospitality and temporary sojourn. In the next chapter I hope to show that a reconstruction of the Kantian concept of the right to external freedom would lead to a more extensive system of cosmopolitan right than Kant himself offered us.
