Famous quotes containing the word earth:

    The earth yields up her stores, of every ill
    The instigators; iron, foe to man,
    And gold, than iron deadlier.
    Ovid (Publius Ovidius Naso)

    In a sense the world dies every time a writer dies, because, if he is any good, he has been a wet nurse to humanity during his entire existence and has held earth close around him, like the little obstetrical toad that goes about with a cluster of eggs attached to his legs.
    —E.B. (Elwyn Brooks)

    Converse with a mind that is grandly simple, and literature looks like word-catching. The simplest utterances are worthiest to be written, yet are they so cheap, and so things of course, that, in the infinite riches of the soul, it is like gathering a few pebbles off the ground, or bottling a little air in a phial, when the whole earth and the whole atmosphere are ours.
    Ralph Waldo Emerson (1803–1882)
