Famous quotes containing the words twin and/or earth:

    “If they be two, they are two so
    As stiff twin compasses are two;
    Thy soul, the fixed foot, makes no show
    To move, but doth if th’ other do.”
    —John Donne (1572–1631)

    “A sleeping man holds in a circle around him the thread of the hours, the order of years and of worlds. He consults them instinctively upon awaking and in one second reads in them the point of the earth that he occupies, the time past until his arousal; but their ranks can be mingled or broken.”
    —Marcel Proust (1871–1922)
