Introduction

David Chalmers is one of the most important and influential philosophers of consciousness on the contemporary scene. He coined the phrase 'the hard problem of consciousness', and defends 'naturalistic dualism' as an alternative to materialism. In his new book 'Reality+', aimed at a general audience, David explores the big questions of philosophy through the lens of virtual reality. He argues that we don't know whether or not we are in a computer simulation, but that even if we are, it doesn't follow that the physical world around is isn't real. It just means the ultimate nature of the physical world is computational!
