Famous quotes containing the words screens, optical and/or element:
“That, of course, was the thing about the fifties with all their patina of familial bliss: A lot of the memories were not happy, not mine, not my friends’. That’s probably why the myth so endures, because of the dissonance in our lives between what actually went on at home and what went on up there on those TV screens where we were allegedly seeing ourselves reflected back.”
—Anne Taylor Fleming (20th century)
“It is said that a carpenter building a summer hotel here ... declared that one very clear day he picked out a ship coming into Portland Harbor and could distinctly see that its cargo was West Indian rum. A county historian avers that it was probably an optical delusion, the result of looking so often through a glass in common use in those days.”
—For the State of New Hampshire, U.S. public relief program (1935-1943)
“Out of the element of participation follows the certainty of faith; out of the element of separation follows the doubt in faith. And each is essential for the nature of faith. Sometimes certainty conquers doubt, but it cannot eliminate doubt. The conquered of today may become the conqueror of tomorrow. Sometimes doubt conquers faith, but it still contains faith. Otherwise it would be indifference.”
—Paul Tillich (1886–1965)
