Famous quotes containing the words blue and/or nature:

    “How prone poor Humanity is to dam up the minutest remnants of its freedom, and build an artificial roof to prevent it looking up to the clear blue sky.”
    —E.T.A.W. (Ernst Theodor Amadeus Wilhelm)

    “What comes over a man, is it soul or mind
    That to no limits and bounds he can stay confined?
    You would say his ambition was to extend the reach
    Clear to the Arctic of every living kind.
    Why is his nature forever so hard to teach
    That though there is no fixed line between wrong and right,
    There are roughly zones whose laws must be obeyed?”
    —Robert Frost (1874–1963)
