Famous quotes containing the words comparison and/or table:

    “What is man in nature? A nothing in comparison with the infinite, an all in comparison with the nothing—a mean between nothing and everything.”
    —Blaise Pascal (1623–1662)

    “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)
