Famous quotes containing the word heart:

    People are less self-conscious in the intimacy of family life and during the anxiety of a great sorrow. The dazzling varnish of an extreme politeness is then less in evidence, and the true qualities of the heart regain their proper proportions.
    Stendhal [Marie Henri Beyle] (1783–1842)

    A man is relieved and gay when he has put his heart into his work and done his best; but what he has said or done otherwise shall give him no peace.
    Ralph Waldo Emerson (1803–1882)

    No man can tell but he that loves his children, how many delicious accents make a man’s heart dance in the pretty conversation of those dear pledges; their childishness, their stammering, their little angers, their innocence, their imperfections, their necessities, are so many little emanations of joy and comfort to him that delights in their persons and society.
    Jeremy Taylor (1613–1667)
