Famous quotes containing the word heart:

    Now wae to thee, thou cruel lord,
    A bluidy man I trow thou be;
    For mony a heart thou hast made sair
    That ne’er did wrong to thine or thee.
    Robert Burns (1759–1796)

    ‘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)

    Then one will say, ‘He is not dead, maybe,
    Who was mortality’s unshaken lover
    Who loved the spring upon the Tennessee,
    The hushed fall and, again, the coming clover.’
    None will recall, not knowing, the twisted roads
    Where the mind wanders till the heart corrodes.
    Allen Tate (1899–1979)
