One of the great books, period.

Roger Penrose seems to only write great books, each is full of new ideas. Penrose has a knack for looking into the dim corners of physics where few others have looked and seeing the contradictions with what "everyone knows".

As with all of Roger Penrose's work, it's excellent. I appreciate the fact that I was made aware of this particular work by Dr. Hameroff as well during presentation I saw on youtube. Both are brilliant men.

Very deep very satisfying when expounding maths, physics and computing. Really enjoyed chapter 2 on Turing machine.

A great example of how not to write a non-science book. Just awful. Save your money for someone who knows how to write these kinds of books, like Brian Greene, Kip Thorne or Sean Carroll.

This book reads like an early draft of Penrose's "Shadows of the Mind." The reader coming afresh to Penrose's ideas would be tempted to skip this earlier book and going straight to Shadows, where the ideas are much more fully developed. The interesting aspect of the earlier work, however, is to see how Penrose's thinking was evolving, purely along physical lines, before he teamed up with the medico and neuroscientist, Stuart Hameroff. It would be a mistake to skip this book, because it is far more readable than "Shadows," the later work being so detailed and technical that many will simply give up on it.

The Emperor's New Mind concentrates on the limitations of formal mathematical logic {as implemented in a computer}, and how human consciousness can stretch past these limitations. Much of this argument is based on Godel's theorems about the limitations of formal systems of logic. Penrose concludes that Artificial Intelligence programs will never, no matter how far computer science develops, be able to produce the kind of conceptual understanding which is characteristic of human consciousness. In a metaphysical leap, he proposes that consciousness is an essentially quantum phenomenon. He gives the "collapse of the wave-function," familiar from conventional interpretations of quantum mechanics, an enhanced status as a real physical effect, and proposes that it is mediated by some {not yet fully understood} effect in Quantum Gravity.

Granted that a conscious observer has featured prominently in discussions of the "measurement problem" from the very beginnings of quantum theory, and that no agreed position has emerged in nearly a century of debate, Penrose's proposal to make the collapse of the wave-function an objective process, and to tie consciousness to it, has more merit than the metaphysical flavour might at first suggest.
