Famous quotes containing the words water and/or quality:
“This sand seemed to us the connecting link between land and water. It was a kind of water on which you could walk, and you could see the ripple-marks on its surface, produced by the winds, precisely like those at the bottom of a brook or lake. We had read that Mussulmans are permitted by the Koran to perform their ablutions in sand when they cannot get water, a necessary indulgence in Arabia, and we now understand the propriety of this provision.”
—Henry David Thoreau (1817–1862)
“Unlimited economic growth has the marvelous quality of stilling discontent while maintaining privilege, a fact that has not gone unnoticed among liberal economists.”
—Noam Chomsky (b. 1928)
