Famous quotes containing the word heart:

    From a great heart secret magnetisms flow incessantly to draw great events.
    Ralph Waldo Emerson (1803–1882)

    Intellectual life is international. Only a period of discouragement, an age that has given up on itself, that wants to “preserve,” that has been driven onto the defensive, can be intellectually nationalist. Such a period is essentially “conservative.” A person who has progress in his heart is international.
    Robert Musil (1880–1942)

    Hate-hardened heart, O heart of iron,
    iron is iron till it is rust.
    There never was a war that was
    not inward; I must
    fight till I have conquered in myself what
    causes war, but I would not believe it.
    Marianne Moore (1887–1972)
