Famous quotes containing the word heart:

    “I struggled with the horror of daybreak,
    I chose it for my lot! If questioned on
    My utmost pleasure with a man
    By some new-married bride, I take
    That stillness for a theme
    Where his heart my heart did seem....”
    —William Butler Yeats (1865–1939)

    “What pity that Religion and Love, which heighten our relish for the things of both worlds, should ever run the human heart into enthusiasm, superstition, or uncharitableness!”
    —Samuel Richardson (1689–1761)

    “Jean Jacques Rousseau ... is nothing but a fool in my eyes when he takes it upon himself to criticise society; he did not understand it, and approached it with the heart of an upstart flunkey.... For all his preaching a Republic and the overthrow of monarchical titles, the upstart is mad with joy if a Duke alters the course of his after-dinner stroll to accompany one of his friends.”
    —Stendhal [Marie Henri Beyle] (1783–1842)
