By reflecting a little on this subject I am almost convinced that those numberless small Circuses we see on the Moon are the works of Lunarians and may be called their Towns.
~ William Herschel [qtd. in Richard Holmes’s The Age of Wonder]
A little reflection is sometimes too much. As a boy I was puzzled by those signs on the side of the highway that read “$1,000 Fine for Littering.” I finally decided the message was a strange sort of permission: If you want to throw thousand dollar bills out the window of your car, well, that’s just fine.
