### Read Shadows of the Mind A Search for the Missing Science of Consciousness

Modern science providing penetrating looks at everything from Turing computability and Godel's incompleteness via Schrodinger's Cat and the Elitzur Vaidman bomb testing problem to detailed microbiology Of particular interest is Penrose's extensive examination of uantum mechanics which introduces some new ideas that differ markedly from those advanced in The Emperor's NewMind especially concerning the mysterious interface where classical and uantum physics meet But perhaps the most interesting wrinkle in Shadows of the Mind is Penrose's excursion into microbiology where he examines cytoskeletons and microtubules minute substructures lying dee. It s a well written easy to follow book on AI and the Godelian argument towards mechanism Penrose ultimately concludes that consciousness cannot be algorithmic that brains are not Turing machines and must be on a uantum level If you re interested in AI it s a good read but the argument itself isn t great it s got a lot of problems and the Godelian argument is widely viewed as unsatisfactory and invalid by the academic community so don t take the book as accurateIf you want a good book on AI and similar arguments just pick up Douglas Hofstadter s Godel Escher Bach2 stars as an academic work 3 as a pop science book

The human mind lie beyond computation This is not a religious argument that the mind is something other than physical nor is it based on the brain's vast complexity the weather is immensely complex says Penrose but it is still a computable thing at least in theory Instead he provides powerful arguments to support his conclusion that there is something in the conscious activity of the brain that transcends computation and will find no explanation in terms of present day science To illuminate what he believes this something might be and to suggest where a new physics must proceed so that we may understand it Penrose cuts a wide swathe through. What can I say about a book which challenged my mathematical understanding and revealed the unseen aspects of my own brain s cytoskeletal structures Was it the knowledge that there is a type of water in these structures which is considered a necessary element for cancelling the interference that would null the necessary conditions for uantum coherence to take effect Or was it the mathematical proof showing that because there are mathematical statements of which we know to be absolutely true yet cannot prove then it follows for us to conclude that a computer could never achieve consciousness at least with the 1994 mathematical understanding available Trust me Roger Penrose does it in a supremely much elegant fashion than I could ever do it justice with in a GoodReads summary So why 4 stars Well I m not an expert at Lambda Calculus or many of the subjects that Roger Penrose expertly weaves in and out of so it became supremely hard to follow at times However I broke through this barrier and was able to glean from it the nuggets that I could understand I recommend anyone interested in these subjects to do the same

A New York Times bestseller when it appeared in 1989 Roger Penrose's The Emperor's New Mind was universally hailed as a marvelous survey of modern physics as well as a brilliant reflection on the human mind offering a new perspective on the scientific landscape and a visionary glimpse of the possible future of science Now in Shadows of the Mind Penrose offers another exhilarating look at modern science as he mounts an even powerful attack on artificial intelligence But perhaps important in this volume he points the way to a new science one that may eventually explain the physical basis of the human mind Penrose contends that some aspects of. The argument is simple There are mathematical problems that can t be solved using algorithms non computable problems If you device an algorithm to solve that kind of problems and let a computer run the algorithm it would never stop Yet the human mathematician is able to solve that kind of problems Computational neuroscience and Artificial Intelligence treats the brain as a computer either there is a neuronal signal or not very much similar to the 0 and 1 scheme But that algorithmic representation can t be truly faithful to what s really going on in the mathematician s brain There must be a non computable ingredientPenrose argues then that there s a deeper level of information processing in the brain deeper than neural networks Microtubules is the best candidate for that Think of a unicellular organism like an amoeba How does it know where to go and what to do It has no nervous system not even a single neuron Yet it does what it does by the means of these cellular automata One thing it appears that things at that molecular level behave according to the strange laws of uantum mechanics providing the non computable ingredient This is an extraordinary approach to the problem of consciousness and Penrose is a humble man although in one of his interviews he pointed out to the interviewer that he should be called Sir Roger Penrose who doesn t claim to have solved the mystery of consciousness He clearly states that the argument is strong at least for the uality of understanding And that other ualities of consciousness like feeling attention imagination can t be simply explained by algorithms only or be regarded as phenomena emerging out of complexity the cerebellum is as complex as the cerebrum yet it s totally automated and unconscious

Penrose's conclusions imply that there is a separate mental world grounded in the physical world and there is also another separate world that of abstract ideas The book is clearly divided in two parts The first part is a proof that traditional Physics is not adeuate to explain consciousness The second part uses uantum

The origins of consciousness are either an elusive mystery or something as painfully obvious as gravity For many

What can I say about a book which challenged my mathematical understanding and revealed the unseen aspects of my own brain's cytoskeletal structures? Was it the knowledge that there is a type of water in these structures which is considered a necessary element for cancelling the interference that would null the necessary conditions for uantum coherence to take effect? Or was it the mathematical proof showing that because there

This book is great feat of human logic It gives in a logical analysis why the human brain can't be a mere computational machine like computers 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

A difficult read I skipped most of the middle section owing to my undergraduate being in physics and the middle section presents an introduction to uantum mechanics I read the initial chapters which go over an argument for why consciousness is not mere computation THe final section goes over the possibility for microtubules to be units of neuronal processing instead of the basic unit being the neuron this greatly expands

I probably would have given Penrose' book a 5 Star review were it not for the fact that a good third of the book was WAY over my head due to the heavy mathematics involved However I did grasp the basic concepts and arguments of the book so 4 Stars will be OKWarning though this book has some heavy math in it You can skim most of th
