Famous quotes containing the word power:
“Power corrupts ... when the weak band together in order to ruin the strong, but not before. The will to power ... far from being a characteristic of the strong, is, like envy and greed, among the vices of the weak, and possibly even their most dangerous one.”
—Hannah Arendt (1906–1975)
“He who has power can be king.”
—Chinese proverb.
“What preoccupies us, then, is not God as a fact of nature, but as a fabrication useful for a God-fearing society. God himself becomes not a power but an image.”
—Daniel J. Boorstin (b. 1914)
