Famous quotes containing the word heart:

    There are two kinds of people one can call reasonable: those who serve God with all their heart because they know him, and those who seek him with all their heart because they do not know him.
    Blaise Pascal (1623–1662)

    The pleasure of leaving home, care-free, with no concern but to enjoy, has also as a pendant the pleasure of coming back to the old hearthstone, the home to which, however traveled, the heart still fondly turns, ignoring the burden of its anxieties and cares.
    Herman Melville (1819–1891)

    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)
