Famous quotes containing the word power:
“Our credulity is greatest concerning the things we know least about. And since we know least about ourselves, we are ready to believe all that is said about us. Hence the mysterious power of both flattery and calumny.”
—Eric Hoffer (1902–1983)
“Swift as a shadow, short as any dream,
Brief as the lightning in the collied night,
That in a spleen unfolds both heaven and earth,
And, ere a man hath power to say “Behold!”
The jaws of darkness do devour it up.
So quick bright things come to confusion.”
—William Shakespeare (1564–1616)
“If Paris lived now, and preferred beauty to power and riches, it would not be called his Judgment, but his Want of Judgment.”
—Horace Walpole (1717–1797)
