Modern translation, Chapter XXII:
It would be an error
to believe that there has never existed anywhere in the world a human authority
that is despotic in all its aspects … Even the greatest power is limited in
some way. If the Grand Seigneur … were
to attempt to impose some new tax, the resulting outcry would be such as to
make him observe the limits to which he had not known he was subject. Although the King of Persia may be able to
force a son to kill his father …, that same King cannot force his subjects to
drink wine. Every nation is dominated by a general spirit, on which its very
power is founded. Anything undertaken in defiance of that spirit is a
blow against that power, and as such must necessarily come to a stop.
Older version (finished in 1876, following the American Civil War and published
in 1882)
It is an error to suppose that there is any human in the world which is,
in all respects, despotic. There never was and there never will be
such. The most enormous power is always limited on some side. Let
the Grand Seigneur impose a novel tax upon Constantinople, and the general
outcry will immediately disclose limits to his power which he had not
known. A king of Persia may indeed constrain a son to kill his father, or
a father to kill his son; but to compel his subjects to drink wine would be
beyond his power. There is in every nation a general spirit upon which
power itself is founded. When it shocks this spirit, power disturbs its
own foundation, and thus necessarily checks itself.
Original French (published in Amsterdam in 1734, without author's name)
C’est une erreur de croire qu’il y ait dans le
monde une autorité humaine, A tous les égards despotique; il n’en a
jamais eu, et il n’y en aura jamais. Le pouvoir le plus immense est toujours
borné par quelque coin. Que le Grand Seigneur mette un nouvel
impôt à Constantinople, un cri général lui fait d’abord trouver des
limites qu’il n’avait pas connues. Un roi de Perse peut bien contraindre
un fils de tuer son père ou un père de tuer son fils ; mais obliger ses sujets
de boire du vin, il ne le peut pas. Il y a, dans chaque nation, un esprit
général sur lequel la puissance même est fondée. Quand elle choque cet
esprit, elle se choque elle-même, et elle s’arrête nécessairement.
