Famous quotes containing the word led:

    Most commonly revolt is born of material circumstances; but insurrection is always a moral phenomenon. Revolt is Masaniello, who led the Neapolitan insurgents in 1647; but insurrection is Spartacus. Insurrection is a thing of the spirit, revolt is a thing of the stomach.
    Victor Hugo (1802–1885)

    I have led her home, my love, my only friend.
    There is none like her, none.
    And never yet so warmly ran my blood
    And sweetly, on and on
    Calming itself to the long-wished-for end,
    Full to the banks, close on the promised good.
    Alfred Tennyson (1809–1892)

    The system was breaking down. The one who had wandered alone past so many happenings and events began to feel, backing up along the primal vein that led to his center, the beginning of hiccup that would, if left to gather, explode the center to the extremities of life, the suburbs through which one makes one’s way to where the country is.
    John Ashbery (b. 1927)
