Famous quotes containing the word permanent:
“During these fits of absolute unconsciousness I drank, God only knows how often or how much. As a matter of course, my enemies referred the insanity to the drink rather than the drink to the insanity. I had indeed, nearly abandoned all hope of a permanent cure when I found one in the death of my wife.”
—Edgar Allan Poe (1809–1849)
“The chief element in the art of statesmanship under modern conditions is the ability to elucidate the confused and clamorous interests which converge upon the seat of government. It is an ability to penetrate from the naïve self-interest of each group to its permanent and real interest.... Statesmanship ... consists in giving the people not what they want but what they will learn to want.”
—Walter Lippmann (1889–1974)
“Let a man learn to look for the permanent in the mutable and fleeting; let him learn to bear the disappearance of things he was wont to reverence; without losing his reverence; let him learn that he is here, not to work, but to be worked upon; and that, though abyss open under abyss, and opinion displace opinion, all are at last contained in the Eternal Cause.”
—Ralph Waldo Emerson (1803–1882)
