reality+
Reality+: Virtual Worlds and the Problems of Philosophy was published by W. W. Norton (US) and Allen Lane (UK) on January 25, 2022. [Information: Norton, Allen Lane, and Amazon.]
Excerpt: the introduction and chapter 1.
Reality+ is my name for the universe of virtual and nonvirtual worlds. You can think of Reality+ as physical reality combined with the metaverse of augmented and virtual realities, perhaps along with a multiverse of alternative realities, simulated and otherwise.
The central thesis of the book is virtual reality is genuine reality. This applies both to full-scale simulated universes, such as the Matrix, and to the more realistic virtual worlds of the coming metaverse.
Simulated universes: The Matrix. I first argue that we can’t know we’re not in a simulation like the Matrix. This is a modern-day version of Rene Descartes’s idea that we might be in the grip of an evil demon producing sensations of an external world. These ideas have led some philosophers to say that we can’t know anything in the world around us is real. But I argue that even if we’re in a simulation like the Matrix, the world around us is perfectly real. There are still tables and chairs, planets and people. If I’m right, a simulation is an “it-from-bit” world where real objects are made of digital processes. This idea helps us to address Descartes’ puzzle of how we can know anything about the external world.
Real virtual reality: The metaverse. I argue that in principle we can lead meaningful lives inside metaverse-style virtual worlds. These worlds needn’t be illusions, hallucinations, or fictions. Our time in them needn’t be escapism. People already lead complex and meaningful lives in virtual worlds such as Second Life, and VR will make this commonplace. I’m not predicting that VR will be a utopia. It poses many dangers and challenges, including the challenge of a corporation-dominated metaverse where corporations serve as the all-powerful and all-knowing gods who create the virtual worlds. (Yes, that’s Mark Zuckerberg in Plato’s cave above.) Like the internet, the metaverse will certainly lead to wonderful things and to awful things. But philosophically, I think it has room for the full range of the human condition.
The problems of philosophy. I use virtual worlds to introduce and address some of the oldest and deepest problems in philosophy. Is there a God? What is the relationship between mind and body? What is reality? How can we lead a good life? How can we build a just society? Thinking about virtual worlds illuminates all of these questions, and transforms some of them. Along the way, you’ll receive an introduction to many areas of philosophy. (The book can easily be used as a textbook in introductory courses and other courses in philosophy.)
All this yields the two-way interaction between technology and philosophy that I call technophilosophy: philosophy helps us to come to grips with new questions about technology, and technology helps us to shed light on ancient questions in philosophy.
The book also contains 57 amazing illustrations by Tim Peacock, three of which are shown above. The chapter 1 excerpt also has four of them: Zhuangzi’s butterfly dream, Narada’s transformation a la Rick and Morty, Mark Zuckerberg running Plato’s cave, and Cornel West on illusions in the Matrix.
Extra material: For people who are reading the book or who have read it, this website includes some extra endnotes and appendices, typically covering more technical matters that may not make sense without the book itself. For academic philosophers, I also have a guide to teaching with Reality+. More coming soon!

Reviews
- Publishers Weekly: “An object lesson in philosophical reasoning and a bold, often awe-inspiring discussion of its implications.”
- Financial Times (John Thornhill): “Scintillating, startling, and sometimes outlandish”
- The Times (Kit Wilson): “A sprawling, brain-tenderising beast of a book — but a hugely entertaining one at that.”
- The Sunday Times (Josh Glancy): “The most alarming and thought-provoking book I’ve read in years… A dangerous manifesto for the future of humanity.”
- The Guardian (P. D. Smith): “I was surprised to find his arguments delightfully – or perhaps worryingly – convincing … A brilliant and very readable philosophical investigation.”
- The Times Literary Supplement (Kieran Setiya): “Outside of ethics, Chalmers is a joy: an exuberant guide through challenging terrain, quick with anecdotes and arguments, wit and wild ideas.”
- Irish Times (Joe Humphreys): “Have you ever read a book that gets under your skin not because you loved it but because it makes an argument so seemingly preposterous that you recoil from it?”
- City Journal (Paul Dicken): “An excellent introduction to the big questions of philosophy—and also an enthusiastic endorsement of our high-tech future.”
- Science (John Zerilli): “[An] intriguing and entertaining romp through philosophy… Chalmers cuts a Gordian knot in writing both accessibly and illuminatingly.”
- New Atlantis (David Bentley Hart): “An essential triviality in its topic — whether minds can exist in virtual worlds — which is nothing more than a beguiling category-error compounded from equal parts bad philosophy and bad science.”
- Washington Post (Jess Keiser): “Like Hofstadter’s work, “Reality+” is frequently weird, wild and wonderful; it captivates the common reader by refusing to condescend.”
- New Statesman (Bruno Maçães): “Reality+ could not be timelier…[Chalmers] is like a migrant who, on arriving at a new neighbourhood in a new country, immediately proceeds to make it look exactly like home.”
- WIRED (Jason Kehe): “The paradox of Chalmers’ “simulation realism,” in fact, is that, once you embrace it, …, so many isms that in modern times have been dismissed as mystical, supernatural—dualism, panpsychism, animism—here find themselves reenchanted, imbued with a profound new vitality.”
- Tricycle (Jordan Quaglia): “I found Reality+ to be a riveting, mind-stretching, wakeful read, one I recommend to anyone fractionally interested in topics such as virtual reality, augmented reality, or our looming omni-cyber-meta-verse.”
- The Philosopher (Tim Crane): “David Chalmers’ new book is a tour de force. … Readable, effortlessly up to date, handsomely produced, and well structured, Reality+ will be a boon for teachers of introductory philosophy courses and is sure to remain on syllabuses for many years.”
- Morning Star (Andy Hedgecock): “Encyclopaedic in scope, leisurely in pace and based on carefully developed explanations, this is the perfect starting point for those with an interest in the possibilities of immersive technology.”
- Philosophy (Yuval Avnur): “Some philosophers are purists, thinking that the problems of philosophy float above the world of changing empirical circumstances. In Reality+, David Chalmers demonstrates the untenability of this purism by showing that technology raises new philosophical questions and changes old ones.”
