Famous quotes containing the word heart:

    Blows the wind to-day, and the sun and the rain are flying,
    Blows the wind on the moors to-day and now,
    Where about the graves of the martyrs the whaups are crying,
    My heart remembers how!
    Robert Louis Stevenson (1850–1894)

    He teaches me to set my heart on nothing. He detaches my mind from friends and relations; and I could watch on as brother, children, mother, and wife all died, and not care in the least.
    Molière [Jean Baptiste Poquelin] (1622–1673)

    The wind’s on the wold
    And the night is a-cold,
    And Thames runs chill
    ‘Twixt mead and hill.
    But kind and dear
    Is the old house here
    And my heart is warm
    Midst winter’s harm.
    William Morris (1834–1896)
