Famous quotes containing the words real, closed and/or field:
“God is a character, a real and consistent being, or He is nothing. If God did a miracle He would deny His own nature and the universe would simply blow up, vanish, become nothing.”
—Joyce Cary (1888–1957)
“The return of the asymmetrical Saturday was one of those small events that were interior, local, almost civic and which, in tranquil lives and closed societies, create a sort of national bond and become the favorite theme of conversation, of jokes and of stories exaggerated with pleasure: it would have been a ready- made seed for a legendary cycle, had any of us leanings toward the epic.”
—Marcel Proust (1871–1922)
“The snow had begun in the gloaming,
And busily all the night
Had been heaping field and highway
With a silence deep and white.”
