"In a quiet and unassuming way, Contraduction is utterly brilliant. Every page has a thought so deep and unexpected that it stops you in your tracks, as you not only realize, 'That’s a different, really interesting way to think about the world, exactly the opposite of how I normally view things” but also, “And it is absolutely equally valid (and enriching) to adopt this opposite way of thinking.' I loved this book." — Robert Sapolsky, author of The Blank Slate and Determined.

"An ingenious word for an invaluable concept. Sharp, clear, and timely." — Steven Pinker, Johnstone Professor of Psychology, Harvard University, and the author of Rationality

"Both a delightful read and a penetrating argument: Barker has invented an invaluable new concept, and puts it to work with clarity, wit, and above all conclusiveness. A must-have book!" — A. C. Grayling, author of The History of Philosophy and The God Argument

"I am completely down with the concept of contraduction. It fills a need. False pattern recognitions pose a real danger to our survival. Well done!" — Ann Druyan, author (with Carl Sagan) of Cosmos, Contact, and Demon Haunted World

"I love it when brilliant ideas are conveyed clearly and soundly. That’s why I love this book. Dan Barker has provided a much-needed explication of a common fallacy that needs to be understood and rebutted. It is an engaging, enlightening, and insightful book."—Phil Zuckerman, author of Society Without God and What it Means to be Moral
