In France, we have an author, philosopher, called La Boétie, who says (I'll do my best to translate him) :
"The one who masters you so much, only has two eyes, two hands, one body, and he hasn't more than any man from any of our city, but the advantage you give to him to destroy you. Where does he take his eyes, with which he watch you, if you don't give it to him ? How has he got so many hands to beat you, if he doesn't take them from you ? [...] How has he any power over you, but BY YOU ? "
