Famous quotes containing the word power:
“Fortune, which has a great deal of power in other matters but especially in war, can bring about great changes in a situation through very slight forces.”
—Julius Caesar [Gaius Julius Caesar] (100–44 B.C.)
“The dissident does not operate in the realm of genuine power at all. He is not seeking power. He has no desire for office and does not gather votes. He does not attempt to charm the public, he offers nothing and promises nothing. He can offer, if anything, only his own skin—and he offers it solely because he has no other way of affirming the truth he stands for. His actions simply articulate his dignity as a citizen, regardless of the cost.”
—Václav Havel (b. 1936)
“We know that madness belongs to love,—what power to paint a vile object in hues of heaven.”
—Ralph Waldo Emerson (1803–1882)
