Reality+ is a book by David Chalmers, originally published in January 2022. This book is an exploration into technology philosophy, or as Chalmers refers to it: Technophilosophy. Chalmers delves into the metaphysics and epistemology, and [ethics]] of reality, incorporating the works of Descartes' Evil Demon, and Bostrom's Simulation Hypothesis, to try to answer some new, and some fundamental questions of reality.
