Famous quotes containing the word power:
“What is good?—Everything that heightens the feeling of power, the will to power, power itself in man.”
—Friedrich Nietzsche (1844–1900)
“Power, I said. Power to walk into the gold vaults of the nations, into the secrets of kings, into the holy of holies. Power to make multitudes run squealing in terror at the touch of my little invisible finger. Even the moon’s frightened of me. Frightened to death. The whole world’s frightened to death.”
—R.C. Sherriff (1896–1975)
“With all of my power of living
I am forced to lie on the floor.”
