Famous quotes containing the word heart:

    “But I saw the little-Ant men as they ran
    Carrying the world’s weight of the world’s filth
    And the filth in the heart of Man—
    Compressed till those lusts and greeds had a greater heat
    than that of the Sun.”
    —Dame Edith Sitwell (1887–1964)

    “The ruin of the human heart is self-interest, which the American merchant calls self-service. We have become a self- service populace, and all our specious comforts—the automatic elevator, the escalator, the cafeteria—are depriving us of volition and moral and physical energy.”
    —Edward Dahlberg (1900–1977)

    “All pathways by His feet are worn,
    His strong heart stirs the ever-beating sea;
    His crown of thorns is twined with every thorn;
    His cross is every tree.”
    —Joseph Mary Plunkett (1887–1916)
