Famous quotes containing the word led:

    The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.
    Nancy Hale (b. 1908)

    I allude to these facts to show that, so far from the Supper being a tradition in which men are fully agreed, there has always been the widest room for difference of opinion upon this particular. Having recently given particular attention to this subject, I was led to the conclusion that Jesus did not intend to establish an institution for perpetual observance when he ate the Passover with his disciples; and further, to the opinion that it is not expedient to celebrate it as we do.
    Ralph Waldo Emerson (1803–1882)

    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)
