Famous quotes containing the word heart:

    O tiger’s heart wrapped in a woman’s hide!
    How couldst thou drain the lifeblood of the child,
    To bid the father wipe his eyes withal,
    And yet be seen to bear a woman’s face?
    Women are soft, mild, pitiful, and flexible;
    Thou stern, obdurate, flinty, rough, remorseless.
    William Shakespeare (1564–1616)

    Not yet has my heart or head
    In the least way realized
    They and I are civilized.
    Countee Cullen (1903–1946)

    Royalty is a government in which the attention of the nation is concentrated on one person doing interesting actions. A Republic is a government in which that attention is divided between many, who are all doing uninteresting actions. Accordingly, so long as the human heart is strong and the human reason weak, Royalty will be strong because it appeals to diffused feeling, and Republics weak because they appeal to the understanding.
    Walter Bagehot (1826–1877)
