Famous quotes containing the word heart:

    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)

    Without comprehension, the immigrant would forever remain shut—a stranger in America. Until America can release the heart as well as train the hand of the immigrant, he would forever remain driven back upon himself, corroded by the very richness of the unused gifts within his soul.
    Anzia Yezierska (1881?–1970)

    The Heart asks Pleasure—first—
    And then—Excuse from Pain—
    Emily Dickinson (1830–1886)
