Famous quotes containing the words noise and/or power:
“Places where he might live and die and never hear of the United States, which make such a noise in the world,—never hear of America, so called from the name of a European gentleman.”
—Henry David Thoreau (1817–1862)
“I know not whether the remark is to our honour or otherwise, that lessons of wisdom have never such power over us, as when they are wrought into the heart, through the ground-work of a story which engages the passions: Is it that we are like iron, and must first be heated before we can be wrought upon?”
—Laurence Sterne (1713–1768)
