Famous quotes containing the words signal, passed and/or danger:
“Certainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.”
—Ursula K. Le Guin (b. 1929)
“You will forget your misery; you will remember it as waters that have passed away.”
—Bible: Hebrew, Job 11:16.
“A monarchy is like a man-of-war—bad shots between wind and water hurt it exceedingly; there is a danger of capsizing. But democracy is a raft. You cannot easily overturn it. It is a wet place, but it is a pretty safe one.”
—Flavius Josephus Cook (1838–1901)
