Famous quotes containing the word tone:
“...I ... believe that words can help us move or keep us paralyzed, and that our choices of language and verbal tone have something—a great deal—to do with how we live our lives and whom we end up speaking with and hearing; and that we can deflect words, by trivialization, of course, but also by ritualized respect, or we can let them enter our souls and mix with the juices of our minds.”
—Adrienne Rich (b. 1929)
