Famous quotes containing the word power:

    It cannot be denied that for a society which has to create scarcity to save its members from starvation, to whom abundance spells disaster, and to whom unlimited energy means unlimited power for war and destruction, there is an ominous cloud in the distance though at present it be no bigger than a man’s hand.
    Arthur Stanley Eddington (1882–1944)

    But it is impossible that the creative power should exclude itself. Into every intelligence there is a door which is never closed, through which the creator passes.
    Ralph Waldo Emerson (1803–1882)

    Of a truth, Knowledge is power, but it is a power reined by scruple, having a conscience of what must be and what may be; whereas Ignorance is a blind giant who, let him but wax unbound, would make it a sport to seize the pillars that hold up the long- wrought fabric of human good, and turn all the places of joy as dark as a buried Babylon.
    George Eliot [Mary Ann (or Marian)
