Famous quotes containing the words blue and/or nature:

    The blue we bathe in is the blue we breathe. The blue we breathe, I fear, is what we want from life and only find in fiction. For the voyeur, fiction is what’s called going all the way.
    William Gass (b. 1924)

    Revenge is a kind of wild justice, which the more a man’s nature runs to, the more ought law to weed it out.
    Francis Bacon (1561–1626)
