Famous quotes containing the words computer and/or science:
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“It is unheard-of, uncivilized barbarism that any woman should still be forced to bear such monstrous torture. It should be remedied. It should be stopped. It is simply absurd that, with our modern science, painless childbirth does not exist as a matter of course.... I tremble with indignation when I think of ... the unspeakable egotism and blindness of men of science who permit such atrocities when they can be remedied.”
—Isadora Duncan (1878–1927)
