A leading philosopher takes a mind-bending journey through virtual worlds, illuminating the nature of reality and our place within it.


Virtual reality is genuine reality; that’s the central thesis of Reality+. In a highly original work of “technophilosophy,” David J. Chalmers gives a compelling analysis of our technological future. He argues that virtual worlds are not second-class worlds, and that we can live a meaningful life in virtual reality. We may even be in a virtual world already.


Along the way, Chalmers conducts a grand tour of big ideas in philosophy and science. He uses virtual reality technology to offer a new perspective on long-established philosophical questions. How do we know that there’s an external world? Is there a god? What is the nature of reality? What’s the relation between mind and body? How can we lead a good life? All of these questions are illuminated or transformed by Chalmers’ mind-bending analysis.


Studded with illustrations that bring philosophical issues to life, Reality+ is a major statement that will shape discussion of philosophy, science, and technology for years to come.



David Chalmers is University Professor of Philosophy and Neural Science and codirector of the Center for Mind, Brain and Consciousness at New York University. He is the author of The Conscious Mind, The Character of Consciousness, and Constructing the World. He has given the John Locke Lectures and has been awarded the Jean Nicod Prize. He is known for formulating the “hard problem” of consciousness, which inspired Tom Stoppard’s play The Hard Problem, and for the idea of the “extended mind,” which says that the tools we use can become parts of our minds.

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.
