 Relations among the states of the world, covered above, are not exhaustive of possible political relations outside one domestic state. Individuals can relate to states of which they are not members and to other individuals who are members of other states. In this they are considered “citizens of a universal state of human beings” with corresponding “rights of citizens of the world” (8:349, footnote). The rights individuals have as citizens of the world form the basis of cosmopolitan right. Based on these lofty sounding pronouncements, some writers inspired by Kant discuss cosmopolitan right as if it were equivalent to general human rights and as if it formed the foundation for worldwide progress. But general human rights in Kant would have to be found in the innate right to freedom, not specifically in cosmopolitan right, and progress toward peace is driven more by republicanism and the behavior of states as discussed in the previous section. Kant’s particular discussion of cosmopolitan right is restricted to the right of hospitality. Since all peoples share a limited amount of living space due to the spherical shape of the earth, the totality of which they must be understood to have originally shared in common, they must be understood to have a right to possible interaction with one another. This cosmopolitan right is limited to a right to offer to engage in commerce, not a right to actual commerce itself, which must always be voluntary trade. A citizen of one state may try to establish links with other peoples; no state is allowed to deny foreign citizens a right to travel in its land. And in an emergency such as a shipwreck, states must provide non-citizens with temporary shelter; this provision is sometimes understood as a basis for a state duty to accept refugees.
