[C] This depravity of human nature is denied by Rousseau, who held
that the mind of man was naturally inclined to virtue, and that
good civil and social institutions are all that is required.
(_Discourse on the Sciences and Arts_, 1750.) Kant here takes
sides with Hobbes against Rousseau. See Kant’s _Theory of Ethics_,
Abbott’s trans. (4th ed., 1889), p. 339 _seq._—esp. p. 341 and
_note_. Cf. also Hooker’s _Ecclesiastical Polity_, I. § 10:—“Laws
politic, ordained for external order and regiment amongst men, are
never framed as they should be, unless presuming the will of man
to be inwardly obstinate, rebellious, and averse from all obedience
to the sacred laws of his nature; in a word, unless presuming man
to be, in regard of his depraved mind, little better than a wild
beast, they do accordingly provide, notwithstanding, so to frame
his outward actions, that they be no hindrance unto the common
good, for which societies are instituted.” [Tr.]

In all these twistings and turnings of an immoral doctrine of
expediency which aims at substituting a state of peace for the
warlike conditions in which men are placed by nature, so much at
least is clear;—that men cannot get away from the idea of right in
their private any more than in their public relations; and that they
do not dare (this is indeed most strikingly seen in the concept of
an international law) to base politics merely on the manipulations
of expediency and therefore to refuse all obedience to the idea of
a public right. On the contrary, they pay all fitting honour to the
idea of right in itself, even although they should, at the same time,
devise a hundred subterfuges and excuses to avoid it in practice, and
should regard force, backed up by cunning, as having the authority
which comes from being the source and unifying principle of all
right. It will be well to put an end to this sophistry, if not to
the injustice it extenuates, and to bring the false advocates of the
mighty of the earth to confess that it is not right but might in
whose interest they speak, and that it is the worship of might from
which they take their cue, as if in this matter they had a right to
command. In order to do this, we must first expose the delusion by
which they deceive themselves and others; then discover the ultimate
principle from which their plans for a perpetual peace proceed;
and thence show that all the evil which stands in the way of the
realisation of that ideal springs from the fact that the political
moralist begins where the moral politician rightly ends and that, by
subordinating principles to an end or putting the cart before the
horse, he defeats his intention of bringing politics into harmony
with morals.
