Famous quotes containing the word power:
“The importance of a lost romantic vision should not be underestimated. In such a vision is power as well as joy. In it is meaning. Life is flat, barren, zestless, if one can find one’s lost vision nowhere.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 19 (1962)
“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)
“We are born to action; and whatever is capable of suggesting and guiding action has power over us from the first.”
—Charles Horton Cooley (1864–1929)
