Famous quotes containing the words heat and/or exchange:
“Beware thoughts that come in the night. They aren’t turned properly; they come in askew, free of sense and restriction, deriving from the most remote of sources.”
—William Least Heat Moon [William Trogdon] (b. 1939)
“We shall exchange our material thinking for something quite different, and we shall all be kin. We shall all be enfranchised, prohibition will prevail, many wrongs will be righted, vampires and grafters and slackers will be relegated to a class by themselves, stiff necks will limber up, hearts of stone will be changed to hearts of flesh, and little by little we shall begin to understand each other.”
—General Federation Of Women’s Clubs (GFWC)
