Famous quotes containing the words damage, shells and/or collections:
“For most Northerners, Texas is the home of real men. The cowboys, the rednecks, the outspoken self-made right-wing millionaires strike us as either the best or worst examples of American manliness.... The ideal is not an illusion nor is it contemptible, no matter what damage it may have done. Many people who scorn it in conversation want to submit to it in bed. Those who believe machismo reeks of violence alone choose to forget it once stood for honor as well.”
—Edmund White (b. 1940)
“The only fruit which even much living yields seems to be often only some trivial success,—the ability to do some slight thing better. We make conquest only of husks and shells for the most part,—at least apparently,—but sometimes these are cinnamon and spices, you know.”
—Henry David Thoreau (1817–1862)
“Most of those who make collections of verse or epigram are like men eating cherries or oysters: they choose out the best at first, and end by eating all.”
—Sébastien-Roch Nicolas De Chamfort (1741–1794)
