Famous quotes containing the word led:

    You who led me by the nose,
    I saw you as you were.
    Then I thought of your body
    as one thinks of murder . . .
    Anne Sexton (1928–1974)

    At night the passion came,
    Like the fierce fiend of a distempered dream,
    And shook him from his rest, and led him forth
    Into the darkness.—
    Percy Bysshe Shelley (1792–1822)

    Young women ... you are, in my opinion, disgracefully ignorant. You have never made a discovery of any sort of importance. You have never shaken an empire or led an army into battle. The plays by Shakespeare are not by you, and you have never introduced a barbarous race to the blessings of civilization. What is your excuse?
    Virginia Woolf (1882–1941)
