KANT’S ANTI-IMPERIALISM 191
foreigners raise issues of justice that can only be met by a separate cate-
gory of justice, one that recognizes that the interrelationships among hu-
mans bind them together as fellow citizens of the earth, despite the fact
that they inhabit different sovereign realms. Thus, as Kant makes a point
of emphasizing, humans from different societies owe something to each
other as a matter of justice, not simply as a matter of philanthropy or
generosity, despite the absence of a shared sovereign power that unites
them all. The one innate right of humanity—the protection of the dis-
tinctively human freedom that underlies humanity as cultural agency—
that humans possess simply by being human and not because of any civil
agreements or the possession of citizenship hence receives its most robust
political expression in Kant’s account of cosmopolitan right. In The
Metaphysics of Morals, the three concepts that are said to follow from the
innate right of humanity are equality, freedom, and communication, each
of which is central to Kant’s understanding of cosmopolitan right.
It should be clear, then, why a discussion only of interstate relations is
insufficient for the purposes of discussing political justice at a global level.
The language of justice—or, in Kant’s terms, the domain of right—ex-
tends beyond the borders of any one state and, at a global level, involves
more than just interstate relations. Kant’s statements about cosmopolitan
right suggest that it is not its global scope that distinguishes it from
international right. Instead, cosmopolitan right is unique in that it at-
tempts to articulate a normative ideal that attends to the ethical problems
raised by increasingly common relationships between “[foreign] individ-
uals and states”, in contrast to the traditional purview of the ‘law of
nations’ that pertains mainly to “states in relation to one another (ius
gentium)” (8:349). Presumably, even if the ideal condition of a voluntary
federation of states were met, ethical problems would still be raised by
the manner in which (for example) states and foreigners (or individuals
from different countries) dealt with one another. Such foreign individuals
might act as the agents of a state or they might simply be travellers of the
kind who voyaged frequently in Kant’s day, with no apparent intention of
conquering lands, however much their information might have helped
later colonialists. Bougainville, the eighteenth-century French explorer
who circumnavigated the globe and whose travel writings inspired Di-
derot’s dialogue about Tahiti and imperialism, seems to fit this latter cat-
egory. As we saw earlier, in a book review of Bougainville’s Voyage autour
du monde, Diderot criticized Bougainville’s travels for, perhaps unwit-
tingly, laying the groundwork for what Diderot assumed would be French
colonial activity in the South Pacific. Diderot was, of course, prescient in
this regard; indeed, Tahiti remains one of France’s last colonial outposts.
Yet, unlike Diderot, who proclaimed in his book review that Bougainville
and every other European should simply leave Tahiti alone, Kant never,
