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)
“There is an optical illusion about every person we meet.”
—Ralph Waldo Emerson (1803–1882)
“All forms of beauty, like all possible phenomena, contain an element of the eternal and an element of the transitory—of the absolute and of the particular. Absolute and eternal beauty does not exist, or rather it is only an abstraction creamed from the general surface of different beauties. The particular element in each manifestation comes from the emotions: and just as we have our own particular emotions, so we have our own beauty.”
—Charles Baudelaire (1821–1867)
