Famous quotes containing the word heart:

    Be near me when my light is low,
    When the blood creeps, and the nerves prick
    And tingle; and the heart is sick,
    And all the wheels of Being slow.
    Alfred Tennyson (1809–1892)

    If with love thy heart has burned;
    If thy love is unreturned;
    Hide thy grief within thy breast,
    Though it tear thee unexpressed.
    Ralph Waldo Emerson (1803–1882)

    There comes Poe, with his raven, like Barnaby Rudge,
    Three-fifths of him genius, and two-fifths sheer fudge.
    Who talks like a book of iambs and pentameters,
    In a way to make people of common sense damn metres,
    Who has written some things quite the best of their kind,
    But the heart somehow seems all squeezed out by the mind.
    James Russell Lowell (1819–1891)
