Great illustration

To the editor:

I want to thank Dave Penny and his band of anonymous businessmen for providing me as a biologist with one of those “teachable moments” I so love. He provides just the illustration I needed to illustrate the distinction between rational and delusional thinking and between how scientists develop understanding through careful study of the natural world versus how delusional thinkers use rhetorical tricks, out-and-out lies and slick slogans to manipulate public opinion about scientific ideas.
