Famous quotes containing the word heart:

    Curses, not loud but deep, mouth-honor, breath
    Which the poor heart would fain deny, and dare not.
    William Shakespeare (1564–1616)

    Good-bye, good luck, struck the sun and the moon,
    To the fisherman lost on the land.
    He stands alone at the door of his home,
    With his long-legged heart in his hand.
    Dylan Thomas (1914–1953)

    With steady eye on the real issue, let us reinaugurate the good old “central ideas” of the Republic. We can do it. The human heart is with us—God is with us. We shall again be able not to declare, that “all States as States, are equal,” nor yet that “all citizens as citizens are equal,” but to renew the broader, better declaration, including both these and much more, that “all men are created equal.”
    Abraham Lincoln (1809–1865)
