The right of hospitality entails a claim to temporary
residency whichcannot be refused, if suchrefusalwould involve
the destruction – Kant’s word here is Untergang – of the other.
To refuse sojourn to victims of religious wars, to victims of
piracy or ship-wreckage, when such refusal would lead to their
demise, is untenable,Kantwrites.What is unclear inKant’s discussion
is whether such relations among peoples and nations
involve acts of supererogation, going beyond the call of moral
duty, or whether they entail a certain sort of moral claim concerning
the recognition of “the rights of humanity inthe person
of the other.”
