Famous quotes containing the word branches:
“We are nothing but ceremony; ceremony carries us away, and we leave the substance of things; we hang on to the branches and abandon the trunk and body.”
—Michel de Montaigne (1533–1592)
“Think how stood the white pine tree on the shore of the Chesuncook, its branches soughing with the four winds, and every individual needle trembling in the sunlight,—think how it stands with it now,—sold, perchance, to the New England Friction-Match Company!”
—Henry David Thoreau (1817–1862)
““I couldn’t afford to learn it,” said the Mock Turtle with a sigh. “I only took the regular course.”
“What was that?” inquired Alice.
“Reeling and Writhing, of course, to begin with,” the Mock Turtle replied; “and then the different branches of Arithmetic—Ambition, Distraction, Uglification, and Derision.”
“I never heard of ‘Uglification,’” Alice ventured to say.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
