" The despot subdues his subjects, some of them by means of others, and thus is he protected by those from whom, if they were decent men, he would have to guard against himself; just as, in order to split wood, one has to use a wedge of the wood itself. Such are his archers, his guards, his halberdiers; not that they do not suffer occasionally at his hands, but this riff-raff, abandoned alike by God and man, can be led to endure evil if permitted to commit it, not against him who exploits them, but against those who like themselves submit, but are helpless. "

― Étienne de La Boétie
