What is raving mad?

Famous quotes containing the words mad and/or raving:

“I have lived in both worlds. And I think I prefer, to the indifferent, haphazard, money- mad hurry of the Outside World, that of my world; that sympathy and understanding grown shadowy since I have been away from it so long, still is more real to me than the world I am in now. Not only the spangles and the gay trappings made it colorful; there was an inner color that warmed the soul. And that I miss.”
—Josephine Demott Robinson (1865–1948)

“A mound of refuse or the sweepings of a street,
Old kettles, old bottles, and a broken can,
Old iron, old bones, old rags, that raving slut
Who keeps the till. Now that my ladder’s gone,
I must lie down where all the ladders start,
In the foul rag-and-bone shop of the heart.”
—William Butler Yeats (1865–1939)
