Famous quotes containing the words noise and/or power:
“Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.... Tooting, howling, screeching, booming, crashing, whistling, grinding, and trilling bolster his ego. His anxiety subsides. His inhuman void spreads monstrously like a gray vegetation.”
—Jean Arp (1887–1948)
“A monarchy is the most expensive of all forms of government, the regal state requiring a costly parade, and he who depends on his own power to rule, must strengthen that power by bribing the active and enterprising whom he cannot intimidate.”
—James Fenimore Cooper (1789–1851)
