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)
“The convent, which belongs to the West as it does to the East, to antiquity as it does to the present time, to Buddhism and Muhammadanism as it does to Christianity, is one of the optical devices whereby man gains a glimpse of infinity.”
—Victor Hugo (1802–1885)
“Justice has its anger, my lord Bishop, and the wrath of justice is an element of progress. Whatever else may be said of it, the French Revolution was the greatest step forward by mankind since the coming of Christ. It was unfinished, I agree, but still it was sublime. It released the untapped springs of society; it softened hearts, appeased, tranquilized, enlightened, and set flowing through the world the tides of civilization. It was good. The French Revolution was the anointing of humanity.”
—Victor Hugo (1802–1885)
