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 The Blank Slate and 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

With Contraduction, Dan Barker gives us a new word—and a new way of looking at things. I thoroughly enjoyed this! So much to think about—and it made me laugh. What else could I ask for? — Kate Cohen, contributing columnist for the Washington Post and author of We of Little Faith

I love how Dan Barker offers us a new word to help us understand how to think rationally in a fun, simple way. I will never look at my reflection in the mirror the same! — Bailey Harris, author of My Name is Stardust
