Famous quotes containing the word heart:

    Can love be controlled by advice?
    Will Cupid our mothers obey?
    Though my heart were as frozen as ice,
    At his flame ‘twould have melted away.
    When he kissed me so closely he pressed,
    ‘Twas so sweet that I must have complied:
    So I thought it both safest and best
    To marry, for fear you should chide.
    John Gay (1685–1732)

    When a man grows old his joy
    Grows more deep day after day,
    His empty heart is full at length
    But he has need of all that strength
    Because of the increasing Night
    That opens her mystery and fright.
    William Butler Yeats (1865–1939)

    They borrow words for thoughts they cannot feel,
    That with a seeming heart their tongue may speak;
    And in their show of life more dead they live
    Than those that to the earth with many tears they give.
    Jones Very (1831–1880)
