Famous quotes containing the word books:
“Indeed, the best books have a use, like sticks and stones, which is above or beside their design, not anticipated in the preface, not concluded in the appendix. Even Virgil’s poetry serves a very different use to me today from what it did to his contemporaries. It has often an acquired and accidental value merely, proving that man is still man in the world.”
—Henry David Thoreau (1817–1862)
“Our books are false by being fragmentary: their sentences are bon mots, and not parts of natural discourse; childish expressions of surprise or pleasure in nature; or, worse, owing a brief notoriety to their petulance, or aversion from the order of nature,—being some curiosity or oddity, designedly not in harmony with nature, and purposely framed to excite surprise, as jugglers do by concealing their means.”
—Ralph Waldo Emerson (1803–1882)
“I alternate between reading cook books and reading diet books.”
—Mason Cooley (b. 1927)
