Famous quotes containing the word heart:

    “My heart leaps up when I behold
    A rainbow in the sky:
    So was it when my life began;
    So is it now I am a man;
    So be it when I shall grow old,
    Or let me die!
    The Child is father of the Man;
    And I could wish my days to be
    Bound each to each by natural piety.”
    —William Wordsworth (1770–1850)

    “‘Way down upon de Swanee ribber,
    Far, far away,
    Dere’s where my heart is turning ebber,
    Dere’s where de old folks stay.”
    —Stephen Collins Foster (1826–1884)

    “This letter will be delivered to you by my child,—the child of my adoption,—my affection! Unblest with one natural friend, she merits a thousand. I send her to you innocent as an angel, and artless as purity itself; and I send you with her the heart of your friend, the only hope he has on earth, the subject of his tenderest thoughts, and the object of his latest cares.”
    —Frances Burney (1752–1840)
