KANT ON HUMANITY AND CULTURE 127
history as already having developed significant physical and social skills.
Drawing upon Genesis, he hypothesizes an original human pair in order
to unfold his arguments. Kant notes that he “imagine[s] them not in
their wholly primitive natural state, but only after they have made signifi-
cant advances in the skilful use of their powers.” Thus, “the first human
being” could stand, walk, speak, talk (“speak with the help of coherent
concepts”), and “consequently think.” Kant demurs from speculating
about how humans could possibly have reached this physical and cogni-
tive level. He contends that “the reader might find too many conjectures
and too few probabilities if I were to try to fill this gap, which presumably
occupied a considerable interval of time.” (8:110) As we will see, Kant’s
method relies upon a conjectural ability to create a story of origin and
development that can be discerned from current evidence—“the guid-
ance of experience as mediated by reason”—and so the hypotheses made,
while by their very nature always hypothetical, can at least, in Kant’s view,
avoid amounting to thoroughly unfounded speculations. It becomes
clear at this point, therefore, that while Genesis might provide a “map”,
it is the work of our minds (informed both by experience and imagina-
tion) that will do the travelling; the reader can judge, Kant notes,
“whether the route which philosophy follows with the help of concepts
accords with that which the Bible story describes.” (8:110) In addition to
avoiding hypotheses wholly unconnected to what can be at least partly
justified according to our experiences of human life, Kant also notes
briefly that a wholly primitive description of humanity simply cannot be a
guide for ethical thinking. “I wish merely”, Kant declares, “to consider
the development of human behaviour from the ethical point of view, and
this necessarily presupposes that the skills in question are already pres-
ent.” (8:111) From this claim emerges a key difference between Kant’s
and Rousseau’s approach toward the theorization of human nature, one
that, as I will later discuss, explains much of their political divergences.
There may indeed be an interesting story to tell about the development
of humans’ basic cognitive, physical, and social skills (of the kind Rous-
seau attempts to describe in the early portions of his Discourse on In-
equality), Kant thinks, but such a narrative would have no bearing on our
ethical self-understanding. In what appears to be a consideration of the
state of knowledge in his day, Kant suspects that such stories, like those
attempting to explain the very existence of human beings, would amount
to “wild conjectures” that “cannot be deduce[d] from prior natural
causes”. (8:110) The fundamental point, however, is that they would be
entirely irrelevant to an ethical understanding of humanity. Ethical reflec-
tion, for Kant, takes as its starting point a particular set of shared apti-
tudes that lie well beyond Rousseau’s portrait of primitive or original
humanity. Rousseau’s classic complaint against earlier social contrac-
