In these theories the wavefunction is a physical wave, which undergoes wave function collapse as a physical process, with observers playing no special role. According to Searle, no mathematical function can be used to connect a known VIN with its LPN, but the process of assignment is quite simple—namely, “first come, first served”—and can be performed entirely by a computer.

It was a difficult and slow read but I don’t regret picking it up. Of particular interest is Penrose’s extensive examination of quantum penrpse, which introduces some new ideas that differ markedly from those advanced in The Emperor’s NewMind, especially concerning the mysterious interface where classical and quantum physics meet.

But the book was very intimidating, even for a computer science graduate. Penrose believes that consciousness is a manifestation of the quantum cytoskeletal state and its interplay between quantum and classical levels of activity.

The author himself advises most of the readers to omit such sections. May 29, Rian Nejar rated it it was ok. Quantum uncertainty of sommbras particles or fields does not map, by any evidence The author’s stand, that we need new physics to understand the science of consciousnessand that this new physics he believes required is quantum physics, seems more his personal intuition read delusion if you like!

But it is something different from exploring the ordinary properties of the ordinary natural numbers.

Shadows of the Mind: A Search for the Missing Science of Consciousness

This book is substantially better written than Dr. After the argument above he discusses how quantum mechanics might provide a basis for human consciousness. Jun 15, Rob Springer rated it liked it. Engel 6 July Penrose establishes 1 using Godel’s Incompleteness theorem and I doubt many people would take somgras with it it seems intuitively obvious as well.

Even non-mathmeticians can follow the arguments he makes and the philosophy is logical and straightforward.

I probably didn’t appreciate his arguments or the math he presents as well as someone with a stronger science background would but the book still makes a dee of interesting points to thi Since I run in the opposite direction when it comes to mathematics, this was a challenging read. It must depend upon a physics that lies beyond computational simulation p. He takes this disparity to mean that human mathematicians are not describable as menge proof systems and are not running an algorithm, so that pnrose computational theory of mind is false, and computational approaches to artificial general intelligence are unfounded.


Penrose’s first book on the subject of consciousness and artificial intelligence. I know a good deal of physics for an amateur and required a couple of other scientists to understand everything which was being said.

Penrose points to the possibility of “microtubules” part of the cytoskeleton that exist even in single-cell paramecium–and seem sombraas give that cell some level of understanding! Mar 10, Unnikrishnan Rajan rated it liked it Shelves: Not the easiest of reads but incredibly rewarding and for anyone interested in what makes us human, self aware, conscious entities then I would thoroughly recommend it whether in the end you do or don’t agree with his proposition the exploratory journey is worth your time and effort.

The only real redeeming quality of this book is that it presents some interesting proofs regarding turing machines and problems that they can’t ed. However, he does reach the deep conclusion that “whatever brain activity is responsible for consciousness. And in the brain this non-computational process takes place not among the neurons themselves but in cytoskeleton microtubules within neurons. Sep 22, Yubal Masalker rated it really liked it.

In fact, there’s a huge feud going on among scientists and philosophers over mentf a bunch of electrical meat generates “you” and “me. Want to Read Currently Reading Read. Hearing Penrose msnte Hay in resurfaced it only for it again nearly to metne to the plate tectonics of my brain and slip under the continent of my consciousness due to another set of events I began to think there might be a quantum superpostion followed by a collapse of possibilites each time I had this on my ‘must read’ list when it was first published then due to events those things that get in the way o all our plans it slipped below the surface of conscious mind and I forgot about it.

In more esoteric terms, it means consciousness is the result of quantum collapse between information states.

Then he gives other practical examples from brain cells’ basic structures to show how brains might use the mysterious principles of Quantum Physics to function and to having the abilities which surpass immensely the most advanced digital AI and that any digital AI wouldn’t ever possess them in principle.


I skipped over entire sections in the book. The author, Sir Roger Penrose, who is an acclaimed mathematical physicist, asserts on the basis of Godel’s incompleteness theorems, that our brain’s perception is beyond the constraints dictated by these theorems which are true for the mathematics and the algorithms operating in computers. Otherwise we would simply be machines and we would have no consciousness.

Relating to consciousness as just another soon to be mastered field as treated by the so-called “strong AI” proponents seems presumptuous to me, and I find myself more identifiying with Penrose, who treats the subject with a lot more gravity.

Oct 18, Andreas K. The argument runs as follows.

Jun 20, Alex Zakharov rated it it pejrose amazing. But I do feel that Penrose sombra done a good job in conveying the gist of things, and can be sensitive to readers’ different backgrounds sometimes suggesting an Consciousness seems to be one of the deepest and intriguing mysteries on the frontier of science today, and there isn’t much more than speculation on the subject. Penrose basically assumes his readers are familiar with not only quantum physics, his previous work, computation, but also problems of free will.

If Penrose’s theory is correct, basically, computational A.

The drawback of this book is that it contains extensive mathematical-philosophy discussions centered around Godel’s incompleteness theorems, using many symbols in those discussions. Retrieved from ” https: There mentr a difference, however, in that what a logician might refer to as ‘Euclidean geometry’ can indeed be specified with some reservations in terms of a particular formal system, whereas, as Godel has shown, ssombras ‘arithmetic’ cannot be so specified.

Oxford University Press, pp. You can help by adding to it.

This section needs expansion. No matter how we program our NPCs, they’ll never be able to be conscious. But that algorithmic The argument is simple. Overall, I found his ideas fascinating, and I hope that the experimental evidence shows him to be right, at least on the foundational premises of his theories.
