Famous quotes containing the words heat and/or exchange:
“To say nothing is out here is incorrect; to say the desert is stingy with everything except space and light, stone and earth is closer to the truth.”
—William Least Heat Moon [William Trogdon] (b. 1939)
“I sometimes feel a great ennui, profound emptiness, doubts which sneer in my face in the midst of the most spontaneous satisfactions. Well, I would not exchange all that for anything, because it seems to me, in my conscience, that I am doing my duty, that I am obeying a superior fatality, that I am following the Good and that I am in the Right.”
—Gustave Flaubert (1821–1880)
