Ambrose Bierce was a skeptic's skeptic. He makes H.L. "Democracy is the art and science of running the circus from the monkey-cage" Menken look like a lightweight. Very clever piece.
"...the Koran. A book which the Mohammedans foolishly believe to have been written by divine inspiration, but which Christians know to be a wicked imposture, contradictory to the Holy Scriptures."
Bierce didn't need 9/11 to figure that out.
