Famous quotes containing the words large and/or systems:
“Whenever you pray, make sure you do it at school assemblies and football games, like the demonstrative creatures who pray before large television audiences. That is the real goal of the thing. But do not, I urge you, pray all alone in your home where no one can see. That does not get you ratings.”
—Garry Wills (b. 1934)
“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)
