Famous quotes containing the word science:
“When science drove the gods out of nature, they took refuge in poetry and the porticos of civic buildings.”
—Mason Cooley (b. 1927)
“My position is a naturalistic one; I see philosophy not as an a priori propaedeutic or groundwork for science, but as continuous with science. I see philosophy and science as in the same boat—a boat which, to revert to Neurath’s figure as I so often do, we can rebuild only at sea while staying afloat in it. There is no external vantage point, no first philosophy.”
—Willard Van Orman Quine (b. 1908)
