The Emperor's New Mind attacks the claims of artificial intelligence using the physics of computing: Penrose notes that the present home of computing lies more in the tangible world of classical mechanics than in the imponderable realm of quantum mechanics. Penrose states that his ideas on the nature of consciousness are speculative, and his thesis is considered erroneous by experts in the fields of philosophy, computer science, and robotics. Only the later portions of the book address the thesis directly. ![]() Penrose intermittently describes how each of these bears on his developing theme: that consciousness is not "algorithmic". Most of the book is spent reviewing, for the scientifically-minded lay-reader, a plethora of interrelated subjects such as Newtonian physics, special and general relativity, the philosophy and limitations of mathematics, quantum physics, cosmology, and the nature of time. The collapse of the quantum wavefunction is seen as playing an important role in brain function. Penrose hypothesizes that quantum mechanics plays an essential role in the understanding of human consciousness. Penrose argues that human consciousness is non- algorithmic, and thus is not capable of being modeled by a conventional Turing machine, which includes a digital computer. The Emperor's New Mind: Concerning Computers, Minds and The Laws of Physics is a 1989 book by the mathematical physicist Sir Roger Penrose.
