Famous quotes containing the word led:

    I have seen many a bear led by a man: but I never before saw a man led by a bear.
    James Boswell (1740–1795)

    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)

    Women hock their jewels and their husbands’ insurance policies to acquire an unaccustomed shade in hair or crêpe de chine. Why then is it that when anyone commits anything novel in the arts he should be always greeted by this same peevish howl of pain and surprise? One is led to suspect that the interest people show in these much talked of commodities, painting, music, and writing, cannot be very deep or very genuine when they so wince under an unexpected impact.
    John Dos Passos (1896–1970)
