An evolutionary and cognitive account of the addictive mind candy that is humor.

Ever since Plato (who thought we laugh at vice), thinkers as serious as Kant and Freud have put forth theories of our giggles and guffaws. Hurley, Dennett, and Adams go at the problem with the ingenuity of first-rate scientists and the timing of first-rate comics. Not only do they have the riches of evolutionary psychology from which to draw, but they're even funnier than Hegel. -- Rebecca Newberger Goldstein, author of 36 Arguments for the Existence of God: A Work of Fiction The deft use of humor can win a mate, persuade an audience, or make a tyrant quake in his jackboots. Yet no one really understands why the human brain should respond so forcefully to that cocktail of anomaly, indignity, and rhythmic vocalization we call a joke. Hurley, Dennett, and Adams offer a sophisticated analysis of this important phenomenon using high standards of evolutionary explanation -- and no, it is not a turgid academic disquisition, but written with clarity, good cheer, and, of course, wit. -- Steven Pinker, author of How The Mind Works Hurley and his crew cross the road to not just explain a joke, but explain all jokes. Before this book the only comedy that had been peer reviewed and replicated in double-blind experiments was the theory that there's nothing funnier than a smoking monkey. I'm so glad smart people outside of comedy are taking comedy seriously. -- Penn Jillette of "Penn & Teller" MIT Press has come up with a page-turner, a book you can't put down. That is no joke! The authors have dissected the mental state of humor and, instead of dismissing it, instill awe about the beauty of the evolved human mind. Humor at its various levels cleans up our act and plays a magnificent role in making us who we are. -- Michael Gazzaniga, Director, Sage Center for the Study of Mind, University of California, Santa Barbara What's so funny about a robot with a sense of humor? In this highly original analysis, Hurley, Dennett, and Adams try to locate the holy grail, the essence of a joke, by using a variety of tools (from computer science, cognitive science, linguistics, philosophy, and even evolutionary psychology) to dissect why we laugh. This powerful team of authors goes a long way to explain why and when we laugh, and in doing so uncover insights about how the mind works. But like the proverbial millipede who, trying to analyze how he lifts each of his legs in the precise sequence, starts tripping over, readers should beware that getting inside a joke risks dehumorizing it! -- Simon Baron-Cohen, Professor of Developmental Psychopathology and Director, Autism Research Centre, Cambridge University
