Famous quotes containing the words physical and/or media:
“The real stumbling-block of totalitarian régimes is not the spiritual need of men for freedom of thought; it is men’s inability to stand the physical and nervous strain of a permanent state of excitement, except during a few years of their youth.”
—Simone Weil (1909–1943)
“Today the discredit of words is very great. Most of the time the media transmit lies. In the face of an intolerable world, words appear to change very little. State power has become congenitally deaf, which is why—but the editorialists forget it—terrorists are reduced to bombs and hijacking.”
—John Berger (b. 1926)
