Famous quotes containing the words cardinal and/or operations:
“Distrust all those who love you extremely upon a very slight acquaintance, and without any visible reason. Be upon your guard, too, against those who confess, as their weaknesses, all the cardinal virtues.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“A sociosphere of contact, control, persuasion and dissuasion, of exhibitions of inhibitions in massive or homeopathic doses...: this is obscenity. All structures turned inside out and exhibited, all operations rendered visible. In America this goes all the way from the bewildering network of aerial telephone and electric wires ... to the concrete multiplication of all the bodily functions in the home, the litany of ingredients on the tiniest can of food, the exhibition of income or IQ.”
—Jean Baudrillard (b. 1929)
