Famous quotes containing the word science:
“I exulted like “a pagan suckled in a creed” that had never been worn at all, but was brand-new, and adequate to the occasion. I let science slide, and rejoiced in that light as if it had been a fellow creature. I saw that it was excellent, and was very glad to know that it was so cheap. A scientific explanation, as it is called, would have been altogether out of place there. That is for pale daylight.”
—Henry David Thoreau (1817–1862)
“The so-called science of poll-taking is not a science at all but mere necromancy. People are unpredictable by nature, and although you can take a nation’s pulse, you can’t be sure that the nation hasn’t just run up a flight of stairs.”
—E.B. (Elwyn Brooks)
