Reality+: Virtual Worlds and the Problems of Philosophy
One of the Washington Post's Best Nonfiction Books of 2022
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.

Editorial Reviews
"Reality+: Virtual Worlds and the Problems of Philosophy, by the Australian philosopher David J. Chalmers, is a highly lucid and thought-provoking exploration of such matters―from René Descartes's thought experiment about an evil demon controlling the inputs into his brain, to the modern "simulation hypothesis" that asks whether we are already living in an alien metaverse without knowing it. "
― Steven Poole, The Wall Street Journal
"[A] stunning success. [Reality+] is well written, cleverly illustrated, and packed with useful distinctions and powerful arguments. It makes excellent use of both history and contemporary culture to help the general reader understand its key concepts."
― John Schwenkler, Commonweal
". . . Reality+ is frequently weird, wild and wonderful; it captivates the common reader by refusing to condescend."
― Jess Keiser, The Washington Post
"Far and away the most credible articulation of simulation theory to date."
― Jason Kehe, Wired
"In this accessible yet thought-provoking book, readers will encounter everything from Plato's allegory of the cave and John Wheeler's it-from-bit hypothesis to how mind and body might interact in virtual worlds, whether reality is a mathematical structure, and whether we might just be Boltzmann brains floating in a dream world. Chalmers also tackles techno-centric questions like whether smartphones extend our minds, whether the Internet is making us smart or stupid, the threat of deepfakes and alternative facts, and whether there can be an objective reality in a multiverse of virtual worlds."
― Jennifer Ouellette, Ars Technica
"[A] brain-bending new book by the philosopher David Chalmers―Reality+: Virtual Worlds and the Problem of Philosophy―has turned me into a hard-core simulationist. After reading and talking to Chalmers, I've come to believe that the coming world of virtual reality might one day be regarded as every bit as real as real reality. "

Book came damaged (see picture) but this says nothing of Chalmers' work. I haven't read all the book yet, but what I've read so far is great. Chalmers is adept at making hard-to-grasp ideas nicely palatable, even for the layman. There are also wonderful illustrations and pop-culture references throughout. I never thought a serious philosophy book would talk about Descartes and Fortnite within a page, but here we are. Tl;Dr, buy the book if you are even slightly interested but go elsewhere.

David Chalmers has managed to create an immensely interesting, deeply thought provoking piece of work that can be read and enjoyed by all (regardless of educational background). Even after you've finished reading, it will continue to provide endless hours of thought-based, mind-bending entertainment. Enjoy!

Part confession of atheist video game lover and part exploration of simulation theory, this book covers a lot of ground in depth without sacrificing any attention to detail.

Are you familiar with books like "The Science of Star Trek," "The Philosophy of Tolkien," and "The Science of Dune"? All of those are real books. They're generally lowbrow or middlebrow attempts to capitalize on a pop culture property, and they're usually pretty superficial. This book, "Reality+," should have been one of those. They should have called it "The Philosophy of the Matrix." Like many other books of this sort, it's a superficial and lowbrow piece of work. To begin with, the author assumes that you know nothing -- and I mean NOTHING -- of philosophy. I'm not exaggerating. He condescends to explain everything to you as though you were a mere toddler -- including hackneyed and much-repeated thought experiments like Plato's Cave and Zhuangzi's dream of the butterfly. This almost insultingly condescending approach is inexcusable; it's a terrible waste of the reader's time and patience. Another problem is that the author repeatedly references modern pop culture properties, to illustrate his points, or perhaps to borrow points from those other works. This really comes across as lame and childish, as are the really infantile illustrations the book contains. They all add to the impression that the author thinks you're a simpleton. An even more glaring problem is the book's lack of insight and original concepts. It reads, at times, like an oral history or a legal ruling! Here's a representative chapter, somewhat simplified: "[Greek Philosopher] said [A]. [Medieval Monk] said [B]. [Early Modern Philosopher] then said [C]. [Early Modern Philosopher 2] also said [C]. [Modern Philosopher] disagrees, said [D]. [Science Fiction Author] posited [E]. I think that the right answer to this particular philosophical problem is [C], and here's a very short paragraph to explain why. Also, in the TV show Black Mirror... And in The Matrix...." I get that Chalmers isn't exactly blazing his own trail here, that he's (a) writing about the oldest problems of metaphysics and (b) piggybacking onto a discussion that has been very active over these past 40 years, but still. It would be nice to see some insight, some rigor, some depth and complexity. We get, instead, thin gruel; easily 80% of the book is a recitation of precedent. This might actually a decent book if you're home-schooling a 10 year old and want to give your kid an introduction to very basic philosophical concepts. (And you can watch The Matrix with them afterwards, hah.) This book's peculiar brand of hand-holding, cartoons, and pop-culture references might make sense in that context. But in every other context, it's laughably bad. I refuse to believe that it was written for an adult audience.

An insightful read on the physical and virtual worlds we are apart of.
