Famous quotes containing the words hour and/or direction:

    Yet, when the walls of flesh grow weak,
    In such an hour it may well be,
    Through mist and darkness, light will break,
    And each anointed sense will see.
    Ernest Christopher Dowson (1867–1900)

    Exaggeration is in the course of things. Nature sends no creature, no man into the world, without adding a small excess of his proper quality. Given the planet, it is still necessary to add the impulse; so, to every creature nature added a little violence of direction in its proper path, a shove to put it on its way; in every instance, a slight generosity, a drop too much.
    Ralph Waldo Emerson (1803–1882)
