- 1761, Jean-Jacques Rousseau, A discourse upon the origin and foundation of the inequality among mankind, page 155:
  It therefore appears to me incontestibly true, that not only Governments did not begin by arbitrary Power, ..., but even that, allowing they had commenced in this manner, such Power ... could never have served as a Foundation to the Rights of Society, nor of course to the Inequality of Institution.
