Famous quotes containing the word led:

    AIDS was ... an illness in stages, a very long flight of steps that led assuredly to death, but whose every step represented a unique apprenticeship. It was a disease that gave death time to live and its victims time to die, time to discover time, and in the end to discover life.
    Hervé Guibert (1955–1991)

    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)

    But don’t despise error. When touched by genius, when led by chance, the most superior truth can come into being from even the most foolish error. The important inventions which have been brought about in every realm of science from false hypotheses number in the hundreds, indeed in the thousands.
    Stefan Zweig (18811942)
