Famous quotes containing the words ray and/or casting:

    These facts have always suggested to man the sublime creed that the world is not the product of manifold power, but of one will, of one mind; and that one mind is everywhere active, in each ray of the star, in each wavelet of the pool; and whatever opposes that will is everywhere balked and baffled, because things are made so, and not otherwise.
    Ralph Waldo Emerson (1803–1882)

    All we know
    Is that we are a little early, that
    Today has that special, lapidary
    Todayness that the sunlight reproduces
    Faithfully in casting twig-shadows on blithe
    Sidewalks. No previous day would have been like this.
    John Ashbery (b. 1927)
