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。
