The motivation for this book arose, in part, from a need for detailed replies to a number of queries and criticisms from readers of the author's previous book, The Emperor's New Mind , many of whom have gone to extraordinary lengths to avoid the conclusion that there must be something non-computational involved in thinking. Penrose searches for a means, within the constraints of the hard facts of science, whereby a scientifically describable brain might be able to perform the needed non-computational actions. He develops the argument of how quantum effects might have a fundamental relevance to consciousness and to non-computable brain action. Some of the more startling implications of this are based on new scientific information which is discussed in detail, leading to one of the most extraordinary and fundamental implications of quantum theory: quantum entanglement, the process by which the behaviour of `classically' described systems is explicable only in quantum mechanical terms. There is a thorough examination of the implications of G "odel's theorem maintaining that conscious thinking must indeed involve ingredients that cannot adequately be simulated by mere computation.No prior knowledge of quantum theory on the part of the reader is assumed. This book is intended for the general reader; physicists, computer scientists, philosophers, etc.

It was an absolute disappointment after other books of Penrose. It is written about many things, not very didactically. It's not easy to follow the thoughts of Penrose, but the worst thing in this book is that it does not mention the real problems of mind. Even the title of the book should be something else because we have not got anything about the shadows of the mind. I should say that I was not able to read fully the book. Maybe its because English is not my native language, but maybe because this book is not well written. I am very sorry to give only 2 stars to this book but I was not very satisfied with it.

Wow. Roger Penrose at his best - is he ever at anything else? He really never leaves a stone unturned. Anyone who has read "The Emperor's New Mind" (he calls it ENM in this later book) will be thrilled with this. He refuses to "run with the crowd". It really stimulates one's thinking.

I would say its just as good as "The Emperor's New Mind". Its technical, and some of it goes over my head, but the reasoning is excellent. I like his style of writing.

The idea that the Earth orbits the sun is so counter intuitive, that if you where not taught this in school, you will have no way of knowing this.Read more
Very interesting book but needs focus and challenges the mind. Great read while travelling
