Famous quotes containing the word heart:

    People, I just want to say, you know, can we all get along? Can we get along? Can we stop making it, making it horrible for the older people and the kids?
    A man cannot know himself better than by attending to the feelings of his heart and to his external actions, from which he may with tolerable certainty judge “what manner of person he is.” I have therefore determined to keep a daily journal.
    James Boswell (1740–1795)

    Poor shad! where is thy redress? When Nature gave thee instinct, gave she thee the heart to bear thy fate? Still wandering the sea in thy scaly armor to inquire humbly at the mouths of rivers if man has perchance left them free for thee to enter.
    Henry David Thoreau (1817–1862)

    The heart may think it knows better: the senses know that absence blots people out. We really have no absent friends. The friend becomes a traitor by breaking, however unwillingly or sadly, out of our own zone: a hard judgment is passed on him, for all the pleas of the heart.
    Elizabeth Bowen (1899–1973)
