A David Chalmers book is a competition. On the one hand the writing is so clear and engaging that you want to keep turning pages; on the other, the ideas are so surprising and profound that you are continually stopping to think about them. Reality+ is a treasure trove of provocative reflections on cosmology, consciousness, artificial intelligence, ethics, and more. Reading it will change the way you think about the universe.--Sean Carroll, author of Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime Fasten your seatbelt and put your helmet on, David Chalmers is going to take you on an amazing trip. Reality+ is wild, profound, and playful, placing famous arguments from the history of philosophy next to surprising observations about video games. Cleverly disguised as light reading, this book carries a large payload of new ideas about existence, knowledge, and what makes life worth living.--Jennifer Nagel, University of Toronto As humanity enters a brave new world of artificial superintelligence and computer-generated virtual realities, how can we humble hunter-gatherers, descended from cavemen, begin to grasp our astonishing technological future? The answer lies in this book.

We must think about the ultimate nature of reality. In Reality+ David Chalmers provides the roadmap to your future.--Susan Schneider, NASA/Library of Congress Chair in Astrobiology, Exploration, and Scientific Innovation, and author of Artificial You: AI and the Future of Your Mind A stunning achievement. In effortless prose David Chalmers explores new ways to think about everything from consciousness to computation, deities to democracy. Reality+ shows time and again how familiar topics take on interesting new forms when viewed through the lens of virtual reality.--Scott Sturgeon, author of The Rational Mind.
