Famous quotes containing the words large and/or systems:
“All sailors pause to watch a steamer, and shout in welcome or derision. In one a large Newfoundland dog put his paws on the rail and stood up as high as any of them, and looked as wise. But the skipper, who did not wish to be seen no better employed than a dog, rapped him on the nose and sent him below. Such is human justice!”
—Henry David Thoreau (1817–1862)
“Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.”
—Friedrich Dürrenmatt (1921–1990)
