Famous quotes containing the words science and, science and/or technology:
“Our civilization is shifting from science and technology to rhetoric and litigation.”
—Mason Cooley (b. 1927)
“Science is analytical, descriptive, informative. Man does not live by bread alone, but by science he attempts to do so. Hence the deadliness of all that is purely scientific.”
—Eric Gill (1882–1940)
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
