“Our civilization is shifting from science and technology to rhetoric and litigation.”
—Mason Cooley (b. 1927)
“We would be a lot safer if the Government would take its money out of science and put it into astrology and the reading of palms.... Only in superstition is there hope. If you want to become a friend of civilization, then become an enemy of the truth and a fanatic for harmless balderdash.”
—Kurt Vonnegut, Jr. (b. 1922)
“Man lives for science as well as bread.”
—William James (1842–1910)
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
