Gödel, Escher, Bach by Douglas R. Hofstadter

% of readers think this story is Fact. Add your two cents.

Gödel, Escher, Bach: An Eternal Golden Braid, also known as GEB, by Douglas R. Hofstadter was the most challenging nonfiction book that I have ever read. Not including notes, my version of the book contained 737 very dense pages. The book was not only difficult, but its structure and content, though based on real science and technology, was very unusual. This work has something of a cult status with people who are interested in human consciousness, mathematics, computers, general science and popular philosophy. It also won the Pulitzer Prize for General Literature in 1979.

Even describing what the book is about is challenging. Hofstadter looks at multiple natural and human-made processes involving loops, self-reference and copying and then relates these concepts to the human brain, thinking, our sense of self and consciousness. He ultimately contends that loops and self-reference are the keys to human consciousness. Along the way, he examines loops, copying and self-reference in terms of mathematics, art, music, physics, DNA, computers and more. He delves into each of these subjects in great, and sometimes bewildering, detail. The mathematical sections are the most intricate. There are many pages that are heavy with formulas and number theory. The author actually gives the reader problems and puzzles to work on to help him or her to better understand it all. There are also very complex sections on the other subjects mentioned.

Hofstadter is particularly interested in Kurt Friedrich Gödel’s Mathematical theorems, the artwork of M.C.Escher and the music of Johann Sebastian Bach as they relate to the topics explored in this book. It turns out the works and discoveries of all three are heavy with loops and self-reference. There are also a lot of words devoted to other mathematicians, scientists, philosophers and classical composers.

Each section of the book is prefaced within an allegorical story involving the characters Achilles and the tortoise. Hofstadter explains in the text that these characters were first used by the Greek philosopher Zeno of Elea and later by Lewis Carroll in “What the Tortoise Said to Achilles”. These segments become longer and more intricate as the book progresses. These stories seek to explain the concepts of each section in parable form. I found these sequences to be charming and whimsical, but they also became complicated at times.

The book is not all technical. In addition to the above-mentioned parables, there is a lot of philosophizing. The author tends to throw out curious ideas and concepts and not actually take stands on them. He is also a good writer who is usually very lively despite the technical nature of much of it. Here, he ponders what it is to be human and our sense of self.

“What is an “I”, and why are such things found (at least so far) only in association with, as poet Russell Edson once wonderfully phrased it, “teetering bulbs of dread and dream” — that is, only in association with certain kinds of gooey lumps encased in hard protective shells mounted atop mobile pedestals that roam the world on pairs of slightly fuzzy, jointed stilts?”

Hofstadter is also an exuberant writer. His love of math, science, Classical Music, art and more exudes through the pages of this work.

When I say that I have read a book, I usually mean that I read every page and every word. However, with this work, I skipped sections. In particular, I passed over much of the math. I tried to read the early and late paragraphs of these sections in order to get the point that the author was trying to make. I read most, but not all of, sections on physics, biology and music theory. I know a little bit about all these subjects as I have taken classes and/or read about all of them. With that, all of these sections were challenging, and there was a lot that I did not understand. I think that had I given it a more comprehensive read, I would have spent the better part of a year on this book. I would have done all of the author’s problems and perhaps gone beyond the book itself to understand all the music theory, technical issues and science. I still would not have understood it all. What is puzzling is that this work is not presented as something for only mathematicians or scientists or experts in music theory to read. Even if it was, I suspect that experts in one of these disciplines might get in over their heads in the areas in which they are not specialists. The depths that Hofstadter plumbs in regards to these subjects are astounding. On one hand, such detail seems unnecessary. On the other hand, the very deep dives into these subjects make the book strangely attractive. This level of complexity seems to be what drives some of the cult status of this book. I should mention that Hofstadter is no crackpot and my understanding is that experts in the respective fields generally respect the information in this work.

My take on Hofstadter’s ideas is that I think that he examines some real phenomenon involving loops and self-reference that cut across both nature and human endeavors. Some of this does relate to the human mind. I am not sure if I agree that these things are central to consciousness and the human sense of self or not. Reading what people have written about this book online, it seems that many take in the grand tour of all of the covered subjects with joy while almost ignoring the author’s take on consciousness.

Hofstadter has written a follow up to this book called I Am a Strange Loop. Perhaps it goes with the odd character of this book in that I read it in an odd way. After reading about one quarter of this work, I put it down and read I Am a Strange Loop as the latter book presented Hofstadter’s ideas in an easier to digest way. I then returned to this work and finished it. I will be posting commentary in that later book soon. I actually found this odd reading sequence to be beneficial. The concepts in I am a Strange Loop were much easier to grasp, and reading that work helped me a lot here.

No matter what, this is a really unique book. In some ways it is a crazy, unpredictable trip through a hodgepodge of ideas. It seems to have influenced many of today’s thinkers. I would only recommend it to those who do not mind a challenging read full of technical material, some of which they may need to skip or skim over. I would recommend it for anyone who is curious about the list of subjects referenced. People who are very interested in mathematics might enjoy this a lot, but only if they have an interest in the other subjects. Though written at a later time, it might be a good idea to read I Am a Strange Loop. In the end, a difficult and strange, but in some ways, rewarding read.

This is a blog about good books. It is a place for me to share my musings about literature, history, culture and science. Most of what one will find here are not plain reviews. Instead, when I discuss a book I tend to explore a thought or two that I have about the work. This is a place for the enthusiastic reader who is curious about the world!
