206 CHAPTER FIVE
Such statements in Kant’s thought indicate that there may in fact be
universal features of human life that could impel nomadic societies to
become agrarian and sedentary over time by the volition of such peoples
themselves. For Kant, this would be a mixed blessing, for as his writings
make clear, civilized societies offer both greater opportunities (at least for
the privileged in such societies, as he notes) for the development of a
wide range of human capacities and the development of aesthetic human-
ity, which he very much values, while they also create and perpetuate
massive injustices not only to themselves but very often to other peoples.
It remains an open question, then, whether Kant believed, like Diderot,
that sedentary, civilized societies, without conquests and imperial rule,
would have developed in all areas of the world. Still, the upshot of all
these considerations is that Kant’s social contract doctrine in particular is
not meant to suggest that the peoples of the New World should (it is an
open question whether they freely will at some point) eventually form
sedentary societies. The social contract doctrine for Kant is a hypothetical
theory—an “Idea” in his terminology, just like his philosophy of histori-
cal progress—that he admits has little or no historical or empirical basis,
but that serves as an ideal with which especially European states and the
international relations of his day could be assessed.

A third aspect of Kant’s understanding of a social contract is that such a
contract is meant to provide a normative orientation for the political prac-
tices of “states”, that is, of settled, agricultural societies that are charac-
terized by the public administration of justice (a Rechtstaat). Kant’s social
contractarianism obligates individuals in such societies to strive perpetually
toward freer, more just, and less violent political conditions. A limitation of
Kant’s political theory, insofar as it constrains his ability to come to terms
with human diversity, is a common assumption of much eighteenth-cen-
tury political thought: civil life, in its fullest sense, requires a sedentary,
agriculturally based society. Thus, Kant describes nonsedentary groups,
including New World peoples, as tribes, societies, or peoples, but never as
constituting states. In this respect, the most humanitarian sixteenth-cen-
tury Spanish theologians, especially Las Casas, had a much broader and
more flexible understanding of the kinds of societies that one might con-
sider to be political. Since he was writing within a Christian Aristotelian
tradition, for Las Casas to prove that Amerindians were fully human be-
ings, he needed to show that they were political beings, given Aristotle’s
fundamental claim that “man is by nature a political animal”. But if politics
and political life are viewed more narrowly and artificially, if they refer to a
centralized, public power that is constructed either by consent or by force,
then a defence of others as human beings need not show that other peoples
are law-governed and civil. Thus, for Kant, the assumption that Africans,
Amerindians, South Pacific Islanders, and Australian aboriginal groups are
human and that they live their collective lives in a human manner consists
