Reality+: Virtual Worlds and the Problems of Philosophy

Virtual reality is rapidly becoming part of everyday life, raising profound questions about the nature of existence itself. If we spend our lives in immersive digital environments, are those experiences any less real? And if we were living inside a computer simulation, would that diminish the meaning of our lives?
Drawing on decades of work in philosophy of mind and consciousness, David J. Chalmers argues that virtual worlds are genuine realities rather than mere illusions. Bringing together ideas from philosophy, cognitive science, computer science, and popular culture, he explores consciousness, simulation, artificial intelligence, and the future of digital existence.
Provocative, accessible, and deeply original, Reality+ offers a new philosophical framework for understanding virtual reality and challenges readers to rethink what it means for something—or someone—to be real.
