Famous quotes containing the words table and/or universal:

    “A big leather-bound volume makes an ideal razorstrap. A thin book is useful to stick under a table with a broken caster to steady it. A large, flat atlas can be used to cover a window with a broken pane. And a thick, old-fashioned heavy book with a clasp is the finest thing in the world to throw at a noisy cat.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    “Really to see the sun rise or go down every day, so to relate ourselves to a universal fact, would preserve us sane forever.”
    —Henry David Thoreau (1817–1862)
