Famous quotes containing the word extremes:
“Moderation shifts when extremes do.”
—Mason Cooley (b. 1927)
“Complete courage and absolute cowardice are extremes that very few men fall into. The vast middle space contains all the intermediate kinds and degrees of courage; and these differ as much from one another as men’s faces or their humors do.”
—François, Duc De La Rochefoucauld (1613–1680)
