Famous quotes containing the words table and/or elements:

    “They were not on the table with their elbows.
    They were not sleeping in the shelves of bunks.
    I saw no men there and no bones of men there.”
    —Robert Frost (1874–1963)

    “It is a life-and-death conflict between all those grand, universal, man-respecting principles which we call by the comprehensive term democracy, and all those partial, person-respecting, class-favoring elements which we group together under that silver-slippered word aristocracy. If this war does not mean that, it means nothing.”
    —Antoinette Brown Blackwell (1825–1921)
