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.
