Twenty years after it topped the bestseller charts, Douglas R. Hofstadter's Gödel, Escher, Bach: An Eternal Golden Braid is still something of a marvel. Besides being a profound and entertaining meditation on human thought and creativity, this book looks at the surprising points of contact between the music of Bach, the artwork of Escher, and the mathematics of Gödel. It also looks at the prospects for computers and artificial intelligence (AI) for mimicking human thought. For the general reader and the computer techie alike, this book still sets a standard for thinking about the future of computers and their relation to the way we think. Hofstadter's great achievement in Gödel, Escher, Bach was making abstruse mathematical topics (like undecidability, recursion, and 'strange loops') accessible and remarkably entertaining. Borrowing a page from Lewis Carroll (who might well have been a fan of this book), each chapter presents dialogue between the Tortoise and Achilles, as well as other characters who dramatize concepts discussed later in more detail. Allusions to Bach's music (centering on his Musical Offering) and Escher's continually paradoxical artwork are plentiful here. This more approachable material lets the author delve into serious number theory (concentrating on the ramifications of Gödel's Theorem of Incompleteness) while stopping along the way to ponder the work of a host of other mathematicians, artists, and thinkers. The world has moved on since 1979, of course. The book predicted that computers probably won't ever beat humans in chess, though Deep Blue beat Garry Kasparov in 1997. And the vinyl record, which serves for some of Hofstadter's best analogies, is now left to collectors. Sections on recursion and the graphs of certain functions from physics look tantalizing, like the fractals of recent chaos theory. And AI has moved on, of course, with mixed results. Yet Gödel, Escher, Bach remains a remarkable achievement. Its intellectual range and ability to let us visualize difficult mathematical concepts help make it one of this century's best for anyone who's interested in computers and their potential for real intelligence. --Richard Dragan Topics Covered: J.S. Bach, M.C. Escher, Kurt Gödel: biographical information and work, artificial intelligence (AI) history and theories, strange loops and tangled hierarchies, formal and informal systems, number theory, form in mathematics, figure and ground, consistency, completeness, Euclidean and non-Euclidean geometry, recursive structures, theories of meaning, propositional calculus, typographical number theory, Zen and mathematics, levels of description and computers; theory of mind: neurons, minds and thoughts; undecidability; self-reference and self-representation; Turing test for machine intelligence.

 Worth every hour! July 29, 2009
Stephen J. Metzger (Dallas TX)
"want a brain stretcher? this very interesting format requires time and dedication, but it is well worth the commitment. Hofstadter explores the beauty of patterns and self referential systems throughout this very large volume. In layering the works of Godel, Escher and Bach, he himself creates a fascinating "Golden Braid""
Genius July 23, 2009

I first picked up this book as a pretentious college freshman and went in head first thinking that I would get some sort of badge from completing this immense Pulitzer Prize winning novel in the mathematic community. Nearly 20 years later, I re-read the book and truly understood the intense themes and real significance of the book for the book itself... not for the challenge of completing it. It's a long and challenging read, even for math types, but what you gain from Dr. Hofstadter is the definitive work of cognitive science and it is amazing!
reconciling the software of the mind with the hardware of brain July 22, 2009
David Brockert (Madison, Wisconsin)
This book has a preface by the author. After twenty (20) or so pages, I was thinking, "Can I understand what he wrote about in the rest of this book?" but I persevered and read the whole book. This book is intense, like any philosophical book. His motive is to "suggest ways of reconciling the software of the mind with the hardware of brain" and that is quite an endeavor he succeeds at, sort of. No wonder he won the Pulitzer prize for this book. He talks of how he came to write and develop the book, and then, upon preparing for republication, he decides to not redo the book: it is what it is, from back then, any addition or correction would create a new book, and it can been seen every so often he imagines some stuff that we use daily, like spell correction, that were just not available back then. If he was to do that, he might as well write a whole new book, and that was not in the cards, nor was it the purpose of the new edition.
Gödel goosed him to realize the notions he writes about, but Escher and Bach represent examples of what Gödel was writing and he is thinking about. As you read the introduction you realize this is one educated and well rounded fellow. He describes the development of Bach's preludes and fugues like a music teacher (I realized that I have a recording of Wanda Landowsky playing "The Well-Tempered Clavier" Book 1, preludes and fugues, but that did not help me understand as you will see). Bach worked up various themes and notions through his music and than then did some fancy finagling and out came some thing wild and crazy wonderful. I listened to the recording I have to no avail. This is something you get to know by playing and playing the tunes, a lot, for yourself, but Mr. Hofstadter's exposition explains what is what for you. Escher is easier (visual experiences are more important or easier to comprehend than aural experiences). The pictures are presented as examples of repetition or growth from one thing into another. The idea of repeating or self-reference is important: it is one thing that computers do not do. We can do imagining things as well, but at a more basic level we self-reference creating a hump of ability that computers have to accomplish if they are to get to be self aware or intelligent.
As he said, he wants to understand the hardware of the brain, but in comparison, computers are simpler, but getting more complicated. He is working from the bottom up with computers: machine language, assembly, programing languages, etc. Fro our brains he is working from the top down, trying to see how the thoughts (software) we think get from one point to another. It is difficult because we do not have access to the basic growth of each thought (neurons firing). Logic tries, yet, as that one guy two (2) or three (3) thousand years ago said, "All I know is that I do not know anything." Mr. Hofstadter just comes to that thought in another roundabout way. I kept thinking of sex deviants doing what they do and that if we could look into their heads, we would be hard pressed to see where the impetus for their deviant behavior comes from, how it develops or why they do it. It is somewhere in there, but the thoughts (software) are so complicated that we can not see how it develops into what is expressed. I also think of how we all speak. We talk without thinking (something I am accused of constantly and embarrassingly), but in reality we just do not follow the thought process from what we hear and see, etc., to what we think of it, to what we will say, to saying it. Another thought is what is happening in the brains of mediators, you know, those Zen folks who quiet the mind, what is happening in there then? The mind is just amazing in what it does.
Throughout this book Mr. Hofstadter writes of the mind and the brain like a psychologist, how it works and what it does. He also delves into genetics. His forte is math and all its intricacies. He develops a couple of different math models to illustrate Gödel's incompleteness theorem. The logic starts out straight forward enough, then veers off into some esoteric realm where the notion of paradox lives, and this is where we have to develop our math notions. We can study the properties of prime numbers or infinities, but we always must end up knowing we do not know everything, because our logic can not encompass paradoxes, and they will be somewhere in all we do, or something like that.
As you can see, I was not able to understand his math models, but I think I got the jist of it.
This book reminds me of another book published in 1978, "The Seven Mysteries of Life" by Guy Murchie. It is amazing that they talk of the same things in the same way and for the same reasons. Though this is a treatise on computers and artificial intelligence, and the other is a religious book, sort of, about the awesomeness of life.
As for the artificial intelligence aspect, I like his development towards that goal, but, and I find no fault in the imagining of it, I am disappointed that computers will just be like us. It will not create a Spock like machine, or what science fiction has led us to hope for (see Isaac Asimov, "I, Robot" etc.). I did like his notion of combining genotypes to create new genes, but I am a guy and I like that sort of stuff. I find that I agree with someone who said, "There are much more fun ways to create intelligence, and it is not artificial." If artificial intelligence is not going to be all that great, it is only good to try to develop it for the exercise and the experience it will give us, but otherwise, eh, no big deal.
Great, Excellent, Breathtaking May 15, 2009

Hofstadter takes some very difficult concepts in logic, mathematics, and computing and makes them much more than understandable - he makes them enjoyable. Self-reference, completeness, paradox, artificial intelligence - if you have the courage to approach it at all, you might as well have fun doing it. Read Godel, Escher, Bach. By the way, MIT OpenCourseWare has two courses available (free!) on this book - one at university level and one at high school level. They make great companions to the book. Have fun!
An involving, mind-expanding experience. April 29, 2009
Dustin B. Steinacker
Most people will miss the point of this book. I certainly did in High School. Despite its highly interesting mix of philosophy, artificial intelligence, music, art and mathematics, this book is not really ABOUT any of these things, at least not primarily. This is a book that truly explains how something as complex and sophisticated as human consciousness (really, consciousness of any sort) could be built out of relatively small components.
Hofstadter proposes neither a big picture nor microscopic understanding of the brain, but a conceptual realization of how the two are related. Probably the greatest thought experiment of all time, and also the funniest, most involving book that I have ever read.
A word: Hofstadter is no great self-editor. He's obviously a man of great discipline but also a man of passion regarding his work, which often leads to very wordy, tangential writing. He often beats around the bush with a variety of interesting though often unrelated observations before truly going in for the kill with a mind-blowing point. You'll have to read between the lines from time to time but it's truly worth it.
