Famous quotes containing the word science:
“The belief that established science and scholarship—which have so relentlessly excluded women from their making—are “objective” and “value-free” and that feminist studies are “unscholarly,” “biased,” and “ideological” dies hard. Yet the fact is that all science, and all scholarship, and all art are ideological; there is no neutrality in culture!”
—Adrienne Rich (b. 1929)
“When science drove the gods out of nature, they took refuge in poetry and the porticos of civic buildings.”
—Mason Cooley (b. 1927)
