Famous quotes containing the words ray and/or casting:
“How false is the conception, how frantic the pursuit, of that treacherous phantom which men call Liberty: most treacherous, indeed, of all phantoms; for the feeblest ray of reason might surely show us, that not only its attainment, but its being, was impossible. There is no such thing in the universe. There can never be. The stars have it not; the earth has it not; the sea has it not; and we men have the mockery and semblance of it only for our heaviest punishment.”
—John Ruskin (1819–1900)
“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)
