Famous quotes containing the word power:
“What wouldst thou do, old man?
Think’st thou that duty shall have dread to speak
When power to flattery bows?”
—William Shakespeare (1564–1616)
“It recognizes no morality but a sham morality meant for deceit, no honor even among thieves and of a thievish sort, no force but physical force, no intellectual power but cunning, no disgrace but failure, no crime but stupidity.”
—Woodrow Wilson (1856–1924)
“Racism is when you have laws set up, systematically put in a way to keep people from advancing, to stop the advancement of a people. Black people have never had the power to enforce racism, and so this is something that white America is going to have to work out themselves. If they decide they want to stop it, curtail it, or to do the right thing ... then it will be done, but not until then.”
—Spike Lee (b. 1956)
