“As to the rout that is made about people who are ruined by extravagance, it is no matter to the nation that some individuals suffer.

—Samuel Johnson (1709–1784)
“I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active—not more happy—nor more wise, than he was 6000 years ago.”
—Edgar Allan Poe (1809–1845)
