Famous quotes containing the word heart:

    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)

    blue bead on the wick,
    there’s that in me that
    burns and chills, blackening
    my heart with its soot,
    I think sometimes not Apollo heard me
    but a different god.
    Denise Levertov (b. 1923)

    Into my heart an air that kills
    From yon far country blows:
    —A.E. (Alfred Edward)
