Amazon.com Review:
Some love it, some hate it, but The Emperor's New Mind, physicist Roger Penrose's 1989 treatise attacking the foundations of strong artificial intelligence, is crucial for anyone interested in the history of thinking about AI and consciousness. Part survey of modern physics, part exploration of the philosophy of mind, the book is not for casual readers--though it's not overly technical, it rarely pauses to let the reader catch a breath. The overview of relativity and quantum theory, written by a master, is priceless and uncontroversial. The exploration of consciousness and AI, though, is generally considered as resting on shakier ground.
Penrose claims that there is an intimate, perhaps unknowable relation between quantum effects and our thinking, and ultimately derives his anti-AI stance from his proposition that some, if not all, of our thinking is non-algorithmic. Of course, these days we believe that there are other avenues to AI than traditional algorithmic programming; while he has been accused of setting up straw robots to knock down, this accusation is unfair. Little was then known about the power of neural networks and behavior-based robotics to simulate (and, some would say, produce) intelligent problem-solving behavior. Whether these tools will lead to strong AI is ultimately a question of belief, not proof, and The Emperor's New Mind offers powerful arguments useful to believer and nonbeliever alike. --Rob Lightner
Product Description:
For decades, proponents of artificial intelligence have argued that computers will soon be doing everything that a human mind can do. Admittedly, computers now play chess at the grandmaster level, but do they understand the game as we do? Can a computer eventually do everything a human mind can do? In this absorbing and frequently contentious book, Roger Penrose--eminent physicist and winner, with Stephen Hawking, of the prestigious Wolf prize--puts forward his view that there are some facets of human thinking that can never be emulated by a machine. Penrose examines what physics and mathematics can tell us about how the mind works, what they can't, and what we need to know to understand the physical processes of consciousness. He is among a growing number of physicists who think Einstein wasn't being stubborn when he said his "little finger" told him that quantum mechanics is incomplete, and he concludes that laws even deeper than quantum mechanics are essential for the operation of a mind. To support this contention, Penrose takes the reader on a dazzling tour that covers such topics as complex numbers, Turing machines, complexity theory, quantum mechanics, formal systems, Godel undecidability, phase spaces, Hilbert spaces, black holes, white holes, Hawking radiation, entropy, quasicrystals, the structure of the brain, and scores of other subjects. The Emperor's New Mind will appeal to anyone with a serious interest in modern physics and its relation to philosophical issues, as well as to physicists, mathematicians, philosophers and those on either side of the AI debate.

it's more than 8 years since I read TENM. The other day I found it fallen on the floor and decided to write a review about it, although I remember it hazily. I was dismayed to see it has 11 1 star revs, against only 23 5 star ones. How is it possible?
I think neg revs misinterpreted the book's intent: here [I hope] we're not in the middle of a religious war, as with string versus loop, or Darwin versus ID, or Sokal versus God knows what (by the way, I'm with Sokal). What Penrose set out to do, IMHO, was to amuse himself a little, and (why not?) also earn some money and get his name away from twistors and spin networks and tiling, and into the public's awareness; and by the way, propound some of his pet hypothesis and beliefs. But all among rational people. I was stunned by the virulence of some neg revs, as if he were rejecting naturalism (and even if so, what?). It seems that civilised discourse is definitely over.
So in my view the book is to be taken first ... Read More

I was compelled to write as I came by on the way to buying Dr. Penrose's more recent book ("Road to Reality") and was appalled that Amazon features 2 out of 3 negative views on the first page, including one which dismisses the "Emperor's new mind" as "rubbish". Surely the book is controversial in certain quarters, but the vehemence of much of the criticism can only make me wonder why some people are so defensive about it.
I have to admit I have not reread this book since my original reading around 1990, so take my remarks at some discount on that basis. But I will tell you that this book remains influential in my choice of what I read and how I evaluate things even to this day. It has indeed changed my life.
Dr. Penrose's premise is that a computer simulation of a brain will not achieve the equivalent of human consciousness. I don't wish to enter the fray of arguing points. Dr. Penrose is a mathematical and scientific genius, a deep thinker on the nature of ... Read More

This book is a real mess, and although I am giving it five stars, I don't really recommend anyone read anything like all of it. In fact, most of it isn't about the problems with strong AI at all. Mostly, it's a general, populist book about modern physics and mathematics. That can be an interesting read too, but probably Penrose isn't the person to be writing such a thing. He uses way too many exclamation points and I suspect he also tends to think he knows more than he really does. For example, it is clear by his one use of the word "ergodic" that he thinks it means something like "single orbits of a measurable set spread out and fill the whole space". That's mixing, not ergodicity. Lots of ergodic transformations do nothing of the kind, like for example irrational rotations of the circle. I only know this because I'm an ergodic theorist; I do tend to wonder how many other things I would catch Penrose speaking as if he knew more about them than he does, if only I knew more about them than ...

Jeez, twelve bucks and one hell of a good read! Stick your neck out and find out for YOURSELF if the book is any good. I'm suspicious that Penrose is being persecuted for theist tendencies.

I skimmed over the equations, and still found the exposition clear enough, with one significant exception. At one point, Penrose describes how an event in the Andromeda galaxy would already have occurred for a person on Earth walking toward the galaxy and not for another at the same spot walking away. The implication is that information would arrive at the same place at significantly different times for people walking in different directions. Penrose is assuming simultaneity of the events on our planet and in the Andromeda galaxy -- after several pages of discussion of how relativity excludes it!
Penrose soon returns to form though, stating that neither person would perceive the event until information about it arrived at the speed of light, millions of years later. Even if people could live that long, they would have to keep walking away from one another to perceive the event at very different times. That would be not be possible on our little round planet.
