Famous quotes containing the word power:
“An actor must communicate his author’s given message—comedy, tragedy, serio- comedy; then comes his unique moment, as he is confronted by the looked-for, yet at times unexpected, reaction of the audience. This split second is his; he is in command of his medium; the effect vanishes into thin air; but that moment has a power all its own and, like power in any form, is stimulating and alluring.”
—Eleanor Robson Belmont (1878–1979)
“There is between sleep and us something like a pact, a treaty with no secret clauses, and according to this convention it is agreed that, far from being a dangerous, bewitching force, sleep will become domesticated and serve as an instrument of our power to act. We surrender to sleep, but in the way that the master entrusts himself to the slave who serves him.”
—Maurice Blanchot (b. 1907)
“The farmer imagines power and place are fine things. But the President has paid dear for his White House. It has commonly cost him all his peace, and the best of his manly attributes. To preserve for a short time so conspicuous an appearance before the world, he is content to eat dust before the real masters who stand erect behind the throne.”
—Ralph Waldo Emerson (1803–1882)
