Over a storied career, philosopher Daniel C. Dennett has engaged questions about science and the workings of the mind. His answers have combined rigorous argument with strong empirical grounding. And a lot of fun. In this book, Dennett shares the “imagination extenders and focus-holders” that he and others have developed for addressing life’s most fundamental questions. Along with novel discussions of familiar moves–Occam’s Razor, reductio ad absurdum–Dennett offers cognitive tools purpose-built for the most treacherous subject matter: evolution, meaning, mind, and free will. From skyhooks to deepities, the Wandering Two-Bitser and the Prime Mammal, Dennett’s genial style persuades as it educates, pointing out pitfalls in arguments as it challenges readers to find others. The result is a sweeping work of deep intellectual seriousness that’s also studded with impish delights. Intuition Pumps offers intrepid thinkers–in all walks of life–delicious opportunities to explore their pet ideas with new powers.
