Famous quotes containing the word heart:

    “Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.”
    —Karl Marx (1818–1883)

    “Although the stupid, unthinking world may approve what you have done, in your heart you know that, but for your treachery, the boy you loved would be alive today. If anyone is responsible for his death, you killed him, and for that murder you will live and die in the contempt and loathing of your own heart.”
    —Karl Brown (1897–1990)

    “While I wrought out these fitful Danaan rhymes,
    My heart would brim with dreams about the times
    When we bent down above the fading coals
    And talked of the dark folk who live in souls
    Of passionate men, like bats in the dead trees....”
    —William Butler Yeats (1865–1939)
