I won’t attempt to debunk it here but suffice to say that Penrose stumbles around even the most obvious objections ex: But that algorithmic The argument is simple. 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.

If that sounds like Greek to you and you’re not Greek, it basically means consciousness exists as a product of physics rather than biology. The situation is, in some ways, perhaps not so very unlike that which occurs with geometry. The author asserts that our brains operate by rules which require consideration of new Physics, particularly the Quantum Physics, in order to explain penorse rise of consciousness out of the brain.

Nov 17, Jimmy Ele rated it really liked it Shelves: His reasoning is too tortured and formula-heavy for me, whom I consider an advanced popular reader. It’s reasonably unlikely that the brain evolved quantum behavior’, he says. Just a moment while we sign you in to your Goodreads account.

Now, in Shadows of the Mind, Penrose offers another exhilarating look at modern science as he mounts an even more powerful attack on artificial intelligence.

Personally, I’m inclined to believe Orch-Or theory is the source of human consciousness. This first half of the book was definitely the hardest to get through, and most people would people would probably be better served to jump to a few key discussions in this first half of the book Penrose makes suggestions along the way on which parts are the most important for people to get the gist. Sir Roger Penrose, one of the smartest men alive, teams up with Doctor Stuart Hammeroff to offer their own version that consciousness is a product of quantum physics “qubits” or quantum information interacting with the microtubbles in the brain.

wombras Such a Platonic viewpoint was important to Godel, and it will be important also for us in the later considerations of this book 8. According to Searle, no mathematical function can be used to connect a known Ds with lax LPN, but the process of assignment is quite simple—namely, “first come, first served”—and can be performed entirely by a computer.

Archived from the original PDF on 7 January The mechanics and technical details of the argument get a little complex Penrose approach is lws systematic, often formal, and quite exhaustive – a large spectrum of mathematical, logical and philosophical corner cases are covered but broad somgras are easy enough to follow.

Subjective reduction is what happens when an observer measures a quantity in a quantum system: Penrose believes that consciousness is a manifestation of the quantum cytoskeletal state and its interplay between quantum and classical levels of activity. In fact, there’s a huge feud going on among scientists and philosophers over why a bunch of electrical meat generates zombras and “me. Ignoring the maths is possible at times, but in certain cases you have to wade through.

According to Marvin Minskybecause people can construe false ideas to be factual, the process of thinking is not limited to formal logic. May 29, Rian Nejar rated it it was ok. Retrieved 7 December O’Connor rated it really liked it.

From Wikipedia, the free encyclopedia. Cover of the hardcover edition. Think of a unicellular organism, like an amoeba. Extremely thought provoking and a real wake up call for those assuming we will achieve the singularity in pfnrose few short decades. I skipped over entire sections in the book. Penrose theorises that the wave function cannot be sustained in superposition beyond a certain energy difference between the quantum states.

As a counter-example, Searle cites the assignment of license plate numbers LPN to specific vehicle identification numbers VINto register a somgras. But even besides it, IMO, the author’s language is not always so friendly for the average reader in his explanations and conclusions about those discussions above. He gives the barest outlines of a new approach to physics he thinks is necessary to bring Mind under the prevue of science.


Great as far as it goes.

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

The main argument that this book presents is incredibly weak. But the book was very intimidating, even for a computer science graduate. One possible candidate for non-computational physics is quantum gravity. Sep 22, Yubal Masalker rated it really liked it. Sep 02, Ronny rated it liked it Shelves: Aug 07, Rajith added it. Apr 16, Ian Murray-Watson rated it really liked it. Of coures this book was written over 15 years ago, so maybe the primary literature has more to say on the matter at this point.

Like many scientists – though it would be more accurate to say like most people – Penrose has his blind spots and prejudices. Penrose ultimately concludes that consciousness cannot be algorithmic, that brains are not Turing machines, and must be on a quantum level.

The logic behind this assertion is both subtle, complex and foundational to all of Penrose’s theories on non-computational physics and the mind, which is why he spends nearly half of the book on this matter. I have referred to three worlds and the mysteries that relate them one to another. Many people still dispute this theory but no one has been able to put up a better one, IMHO.

But I do feel that Penrose has 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.

When he wrote his first consciousness book, The Emperor’s New Mind inPenrose lacked a detailed proposal for how such quantum processes could be implemented in the brain. This OR is claimed to be non-random and non-computational.
