  Strangely Wrong
  
  I must suggest something blasphemously arrogant: Douglas Hofstadter has it wrong. My only justification for saying such an outrageous thing is that it doesn’t matter. Folk will go on taking Hofstadter seriously in any case. Nevertheless I have a valid objection which needs to be recorded. Enough, then, of self-referentiality.
  
  Hofstadter’s teenage intuition got him started on the idea that there are degrees of souledness in the material world. Atoms (and presumably their constituent parts) have no souls; bacteria have very primitive, that is to say, very small souls; dogs have somewhat bigger souls; and human beings have much larger souls but even among those there is enormous variation and no logical upper limit to size. This of course is not an entirely novel intuition. It was shared by Ancient Greek philosophers, pre-industrial tribal groups, perhaps some Shinto sects, and St. Thomas Aquinas among others.
  
  This idea of souledness is of course essentially a moral one. Hofstadter’s explicit intention is to provide a criterion by which he and his fellow human beings can decide how to act - in general the more soul, the more respect should be afforded to its bearer. Incidentally he is also developing a theory of consciousness, which is a correlate of soul.
  
  But this is simply wrong. Hofstadter, from the very beginning of his exceptionally discursive argument, presumes that what he is doing is constructing a metric of souledness through which he can estimate the size of soul or degree of consciousness possessed by an entity.
  
  This is, of course what scientists, and engineers, and husbands who are putting up curtains usually think they are doing when they measure something, namely determining what length, breadth, volume, color, texture, or other magnitude constitutes some entity of interest. The metric employed depends on the interest one has of course.
  
  It is this interest one has, however, and not the molecule, or bridge, or curtain material, which ‘contains’ the result of any measurement. The choice of which metric to employ determines not how much of something is contained in an object but where that object sits in relation to other objects on the metric. The object is a property of the metric; the metric is definitely not a property of the object.
  
  This distinction is crucial in light of Hofstadter’s fundamental motivation to provide a criteria for correct behaviour. The choice of metric is THE moral choice. The thing measured has no moral content at all - not people, not events, not inanimate objects. They are considered as moral (or tall, or wide, or disgusting) when we put them on the scale we have chosen.
  
  The consequence is that Hofstader’s Strange Loop, the ‘I’ of consciousness, is not some objective entity, a logical ego which can be studied scientifically for its salient characteristics. This Strange Loop is literally a moral construction, a consequence of the very metric of souledness that Hofstader chooses. We, not just human beings but all that exists, have no soul whatsoever until someone like Hofstader, or Plato, or Thomas Aquinas comes along and sets up a criterion for assessing it. Then, hey voila, it’s there.
  
  But it’s really not there as well. The mirage that Hofstadter writes about is that the things we measure have the characteristics that we measure. An innocuous self-delusion, except when it’s not. The metric he started with is the Strange Loop, hiding in plain sight, a ninja ego smirking behind his index finger with a Cheshire Cat grin. It was created when Hofstadter said it and someone else heard it. The Strange Loop is not ‘I’, it is ‘We’.
  
  And so the Strange Loop exists in that very strange state we call language, being nowhere specific but lurking invisibly everywhere. This gives the Strange Loop the character of quantum uncertainty: it can be experienced and reflected upon, but never at the same time. Just like the metric of souledness, one of its many masks.

  I have an interesting perspective on this title because the book I read just before it was The New Earth by Eckhart Tolle, a book grounded in Zen Buddhist philosophy. Tolle declares that the Ego (or thinking mind) is the cause of all the poisons of our civilization and the only hope for us as a species is to embrace awareness and presence and escape the thinking mind that feeds our needs for material possessions, success, achievement, domination, and so on. This book is in fact an entire logician’s analysis of what the “Ego” is, which Hofstadter believes is equivalent to the “I,” the Self, the soul, and consciousness itself. In fact Hofstadter believes the Ego is all there is in us. Tolle would probably say…you may be right that the Ego is a strange loop…but so what? It’s poison; cure it! While Tolle occasionally does fall into new-age batshit, overall his analysis was fairly compelling to me. I would also claim that Hofstadter’s equating consciousness, the “I,” and the “Ego” as all one equivalent thing is nothing more than an assertion.
  
  Hofstadter’s essential claim is that the Ego is a strange loop in the mind, and by strange loop he means a feedback loop (or “pattern”) that reflects on itself. Everything in our brain is a symbol, including the symbol of itself. I believe he would say that the Self-symbol is a loop, and the loop is a symbol that is continually reevaluating itself and making slight adjustments to itself. A loop that can observe itself and provide feedback on itself (it’s “self”). We invent this Self-symbol in our minds over our lifetime as it constantly accretes bits of other symbols to it—it provides feedback on itself constantly. I actually agree that this is (possibly) an accurate way to describe much of the Ego. Hofstadter agrees with Buddhism that the Self is an illusion, but he off-handedly says striving to get past the illusion as Buddhism suggests is a pointless, dead-end pursuit.
  
  I did not find that Hofstadter compellingly demonstrates that this strange loop is the entirety of consciousness. Awareness and energy or pure presence seem to be aspects of consciousness which are outside the symbol of the Ego. He tries—but doesn’t succeed in my mind—to dispel that there is something else present. In addition, he seems to confuse our mind's symbol of the “I” with what the “I” might really be. The mind is easily fooled after all so, this strange loop might certainly be an illusion. But also there might be something else we can’t sense because we are so easy to fool.
  
  I think one of the key flaws in his argument is that he doesn’t delve deeply enough into the “self-reflexivity” he talks about. Since this “self-reflexivity” is the very point when a self-symbol examines itself then that very point may well be the point of the conscious mind. He essentially claims the self is a formula, and life is in fact mechanistic. There is no free-will because all your brain is doing is weighing pros and cons of various choices and whichever internal symbol gets the most checkmarks wins. The brain is an infinitely extensible, malleable computer processor and there is no “free” in will, only the choosing based on our brains weighing various symbols. He starts out sounding non-deterministic but in the end came out pro-deterministic. Thought=computation. In fact, he hasn’t really thought it all through. For example: can’t our brain re-evaluate a symbol’s value by thinking about it? By examining it internally, we can uncheck old boxes and check new ones. So in fact there is a consideration that occurs, a self-reflective change, an awareness that could be called “free.” It’s only action without analysis which is not free (at least within the framework he has set up.) This “will” to change is perhaps our moment of freedom.
  
  There is something else to this self-reflective loop that Hofstadter doesn’t consider very thoroughly. Godel’s self-reflective mathematical statements are his model for what the Self is, such as “I am unprovable.” The self-reflective quality of Godel’s theories are certainly clever and very brilliant, but where they part ways with the analogy to human consciousness is our ability to change our formula and take a different direction through awareness. Someone actually wrote Godel’s formula, it didn’t burst into existence on its own. The claim that it represents the model for the self is nothing but a claim unbacked by scientific evidence.
  
  One key outcome of Hofstadter’s analysis is that the “pattern” of the Self, or consciousness, can be distributed between people…so that a piece of his deceased wife’s consciousness exists in him because they were so intimate and her pattern lives on in him. But the flaw in this argument is so blatant, I can’t believe he doesn’t acknowledge it. If we grant him the premise that the Self is a symbol in the mind that the mind is constantly reinterpreting—then the symbol of “my dead wife” exists in his mind as a symbol of her but that symbol does not provide feedback to itself or reinterpret itself. So her consciousness is not distributed, merely a symbol of her is in his mind. The key difference being that (by his own definition) the Self is a self-reflexive symbol but my symbol of someone else—no matter how detailed it is, no matter how intimate we were—does not provide feedback to itself.
  
  He gives us another hypothetical case to reinforce this theory. The story of a man who jumps into what is basically a Star Trek teleporter and is then reintegrated on another planet with every memory, thought, inclination, etc. Is it the same person or a new Self? What if the first person accidentally wasn’t disintegrated but survived? Which of the two would be the “real” man? He concludes that they really both are the real man and thus consciousness can be distributed. What this story lacks is an understanding of how a unique point-of-view makes the self what it is. To me the simple answer is: To other people, these two men will appear in every way the same. But to the individual who is teleported, the experience is not continuous. He simply dies in the first place and is not “reborn”. His consciousness will end and some other person identical to him in every way will be reborn, but his point-of-view of the world will be snuffed out. In the second case, the man who wasn’t disintegrated is the real consciousness while the new one is essentially an insta-clone. It’s not the complicated “grey area” puzzle Hofstadter claims. The clone may think it’s the same person as the previous one because it has the same thoughts and memories, but the man who stepped into the teleporter never had another thought. He died and was replaced by a doppelganger that was convinced it was him in every way. Hofstadter’s vision of distributed consciousness is not compelling.
  
  Finally, in his conclusion, Hofstadter tries to bucket all people into two categories (an annoying habit he has): those who believe all things must follow physical laws (which would include those who agree with his theory), and those who believe in Dualism that would declare that there’s magic in that-there brain, a magic soul that gets squirted in at some point. The obvious flaw here is to assume that we have anywhere near a full grasp on what “physical laws” are. Does Quantum Physics “really” reflect what’s going on down there? Or is it just a metaphor for something we don’t understand at all? What about other universes or dimensions in space/time? So, perhaps there is another point to be made that maybe our “self” does follow a physical law that allows it to exist…but we just haven’t found that law yet. Or maybe physical laws are just abstractions and not so “determined” or concrete anyway. And what about the ambiguity and indeterminacy of quantum action itself? Or maybe something completely other is true that we have never even imagined.
  
  Oh, and his weighing of “souls” by their level of consciousness is creepy. As well as his odd philosophy of how love of Bach makes you a bigger soul.
  
  I Am a Strange Loop is overly-wordy and jammed with a few too many analogies and painful puns, but I enjoyed the intellectual challenge. He truly provides no concrete “reasons to believe” only assertions, which are worth pondering if not agreeing with.

  *Edit December 2022* Came back here just to muse on the idea that Hofstadter's idea of the "strange loop" is more or less an intuitive, philosophical way, rather than a theoretical physics and mathematical way, of getting to the idea of quantum entanglement - which is just marvelous.
  
  *Original Review:*
  
  I’d like to preface the review (which is very long, but if you are vacillating on whether or not to read this book, I hope my review will help you decide to your best interests, whichever those will be. Particularly if you, like me, are decidedly not math-inclined) by saying that I’m a philosophy student. I love philosophy so much it’s disgusting. We’re dating. We moved in together after our third date. We have a wedding registry at Macy’s. So it is with nothing but complete affection that I say many, many, many philosophers- particularly modern, male philosophers- are total fucking assholes who I will happily argue do not possess souls and as such have no business talking about them. But I love their soulless little hearts anyway.
  
  Naturally, I head into “I Am A Strange Loop” expecting more of the same. So you can imagine my surprise when, by page 11, I’m aw’ing at Douglas Hofstadter’s warm little animal-loving soul, and later, when he talks about losing his wife- it’s unbelievably touching. So basically consider me fully indoctrinated to the Hofstadter cult of personality. I am fully ready to drink the Kool-Aid. I am THERE. Show me your world, Douglas.
  
  And what an interesting world. I read this book as a teaser to convince me I need to read Godel, Escher, Bach. I wanted the motivation to read that, because it’s twice as long as “Loop” is and you need to really commit. Successful! This book is fully readable for anyone who likes thinking about thinking.
  
  Contrary to what the other reviewers say, there’s not really that much math. From Page 113 to around 170, there’s some conceptual math he walks you through, but he’s gentle and at least half of that material is anecdotes and analogies, so really you’re look at mayyyybe 20 or 30 pages of actual math and metamathematics. That’s practically a pamphlet, and doable for anyone if you just grit your teeth. But it’s important you read it or the rest of the book will be a waste.
  
  That said, I don’t think it’s important for the *idea* the book outlines. Godel’s discovery that Russell & Whitehead’s Principia Mathematica is self-referential (self-reference in math being the very thing Russell & Whitehead were trying to explain away by writing PM) is an analogy for the main idea of the book, and as such, it’s supposed to elucidate the primary idea. It doesn’t, much. There are many other, much shorter analogies (a good number of which Hofstadter also uses) to introduce the idea that consciousness and perception of the “I” are Mobius strip-esque. An analogy to support an idea shouldn’t take up half the book. While the analogy is sound, it’s superfluous, and I think Hofstadter just loves Godel too much to leave him out of anything (Bach, too. And Escher. We’re treated to all three of his heroes in varying doses). Therefore I agree with other reviews which say this book could have been half this size and gotten the same point across, but I disagree that it *should* have been shorter. I’m glad the Godel analogy (and all the rest of the digressions, which are many but pleasant) was included, because I enjoyed learning about it, and I liked reading the book the way it was written.
  
  Other notes: Douglas, you are a freak. I would have loved to be your mom because you were obviously the kind of kid you could leave in a house alone for days, like a cat, and come back to find you sitting in the exact same spot you left them staring fixedly at his own hands. I say this because he explains that for Video Voyage II (when he pointed a camera at the TV screen which displayed its feed, creating an infinite feedback loop) he spent twelve hours with his friend just playing with that. Dangling shit in front of the camera to see what would happen.
  
  Now, look. That sounds like a fantastic thing to do and I’m going to try it myself when I have the chance. But for an hour. Mayyyyybe two if I’ve had some Adderall or something. But twelve hours? He also names a box of envelopes Epi and carries “her” around for thirty years and counting. He is- perhaps appropriately- loopy. While he clearly recognizes his zaniness, he so obviously doesn’t know the half of it. He’s like what would result if Pee Wee Herman and Hilary Putnam somehow had a baby and dipped it in radioactive ice cream. And I truly mean that as a compliment.
  
  What might be my favourite moment of the book is his explanation of Euclid’s proof on the infinitude of prime numbers. WHAT? you gasp, remembering that I said I am so unmathy there are not words to describe it (amusingly, Hofstadter points out somewhere that in saying that, I have described it- “indescribable” is a descriptive word. Ah, loops and paradoxes). But it’s true. In less than a page, he describes this proof, and if you aren’t familiar with it, it’s a “Eureka!” moment like no other. He leads into the proof by saying it’s a crucial life experience like tasting chocolate or hearing music for the first time. At this, I’m scoffing. Sure, Douggie. For a mathfreak like you, sure. But for me, it is just a page to get through before we go back to the fun philosophy. By the end of it, there are stars in my eyes because I’ve just had the most enjoyable math-related experience of my life because, for the first time, it clicked and it was amazing and it was chocolate. It was music. HE WAS RIGHT.
  
  Nota bene: it's true this book doesn’t have a lot of brand-new ideas- new to me or new to the world. But it does articulate them in more compelling ways than I’ve personally encountered, and in doing so, convinced me more of their possibility. So in that way it was personally transformative.
  
  He gets a lot of criticism for the amount of himself that he puts in the book. There are many personal anecdotes and a lot about the death of his wife. I think that’s important. I think that to write a book on the nature of the “I” for the author to abstract entirely is delusional and as foolhardy as a scientist claiming that science is pure hard fact and doesn’t come with its own set of warping factors and biases. It also, of course, makes for a more readable book, and makes the ideas he defends with those personal stories more convincing.
  
  The philosophical world he describes about midway through the book, Twinwirld, was extremely fun to play with.
  
  He loves to play with words and he loves corny puns. From “simmballs” to “post partyum decompression” there are many winks to make you smile.
  
  I would respectfully but staunchly disagree with interpretations that claim Hofstadter’s take is reductionist. It is not. In no way is he claiming that mental states are irrelevant. Quite the opposite- he is claiming that the body is the least important part of the mind, that the mind can exist outside one body, that in being able to think like someone else, and experience states of mind from or of them, we are them, in a strange way- we don’t carry the most faithful part of them, of course, but we do in some sense have their “soul” (he often uses this word in a non-religious and unromantic way, of course, and really means something more like “essence” or “consciousness”) in part. Because, like a finger waggling in front of a video camera pointed at a screen showing its own feed, souls are strange loops- one small alteration will be played back eternally, and human interaction creates many such alterations, and so just as the finger will exist on those video screens in an infinite loop (infinite so long as the camera and screen hold out without breaking or being moved, obviously) long after the finger is gone (even, in fact, if the owner of the finger is dead and rotted away), and in that way the finger is preserved, sort of, just so a person’s consciousness, when it becomes intertwined with the loops of others’ consciousness, may well be said to endure in some sense after they are dead.

  I read Douglas Hofstadter”s “Godel, Escher, Bach” long ago – sometime in the early ‘80s, and I remember thinking “I really need to read this again. I liked this book, but there was a lot I think I missed.”
  
  When I saw a copy of “I Am a Strange Loop” in a used-book store, and Hofstadter said in the intro it was his update of “Godel, Escher, Bach,” I figured this was my chance to rediscover the concepts in “Godel, Escher, Bach.”
  
  Well, I did, but I can’t say I was happy with the result. Hofstadter’s topic in “I Am a Strange Loop” is consciousness, and the concept of the “I” that we all carry around in our heads. And somewhat like Gilbert Ryle and the other black-box philosophers who believe that mental states are unimportant phenomena, and all that matters is physical behavior, Hofstadter concludes that there is no I there at all. Instead, there are just a bunch of competing desires that he says, using one of his many analogies, compete in the brain for votes, and the one with the most votes gets to see that desire translated into action.
  
  Hofstadter’s primary point is the problem that’s haunted the mind-body dualists since Descartes: How does a thought or idea get transmitted from the non-corporeal plane of mental activity to the decidedly down-and-dirty mass of blood and bone that is human flesh? Hofstadter claims that the I we believe we have is just a convenient fiction our brains have constructed, and that there’s no way our mental beliefs could be translated into physical action.
  
  Of course, Hofstadter’s own theory suffers from the same fundamental problem: How does the winner in the competition between various wishes and desires translate that specific wish and desire into physical action? What is the mechanism that bridges the gap between the world of spirit and the world of flesh?
  
  Absent that key connection, Hofstadter’s alternative to our ingrained belief in our own consciousness, and our own ability to make decisions that we then execute, lacks any real advantage. It’s just another theory about mental states, but one that ignores the reality of our belief in our own identity.
  
  Which leads to a second argument against Hofstadter’s position that there’s no I there: the evolutionary one. If the I really doesn’t exist, why do we think it does? If we don’t have free will, why did we develop this elaborate mental apparatus that makes us think we do? If free will is an illusion, wouldn’t we as a species be better off applying the resources we spend believing in our ability to choose to something more practical, like running faster, or producing more sperm and eggs, or having a better sense of smell? Why would evolution have allowed this strong sense of our own consciousness to use up so much of our mental energy if it was just a figment of our imagination?
  
  Another argument: In the 19th century, there was a great deal of philosophical debate, again going back to Descartes, about the validity of our perceptions about reality. Bishop Berkeley contended that all that existed were ideas, as whatever we perceive is mediated by our brains – and thus even if there were an objective reality, we could have no idea what it was because of the barrier set up by our brain’s interpretation of what our senses transmitted.
  
  Logically, there is no real answer to this contention, but pragmatist G.E. Moore finally simply said “This is my hand” – and the idealists, as they were called, cannot deny that the world operates as though our hands are real, and exist.
  
  Finally, though I could go on, there’s this question: Does Hofstadter himself believe that he doesn’t make choices? Does he really live his life as though his own identity doesn’t matter, and doesn’t make decisions? Does he go to lunch with the other philosophers who believe our mental states cannot translate into action, and wind up just walking aimlessly until they find a Taco Bell? Or do they act as if they could decide that the local taqueria is a better choice?
  
  All that said, I did find parts of “I Am a Strange Loop” well worth reading. Hofstadter’s long explanation of precisely how Kurt Godel demolished the formalist mathematical theories of Bertrand Russell and Alfred North Whitehead is fascinating (if sometimes difficult), and there are other segments early in the book that are very engaging.
  
  But as the book goes on, Hofstadter’s penchant for unusual analogies and his reductionist philosophy take over, and frankly, left me cold. I read the first 200 pages with interest, but it was a struggle to finish “I Am a Strange Loop.”
  
  Oh, and I am now cured of my desire to go back and re-read “Godel, Escher, Bach” – especially since, according to Hofstadter, I don’t really exist at all.

  I didn’t like this book, although I agree with almost all of its assertions. Conceptually, I guess you could say, I enjoyed it, but the presentation - the language of the author, the over-long format, and the strange mixture of hard math and elementary philosophy - diminished and diluted the content to the point that it was barely worth reading. The first problem is Hofstadter’s “aww shucks” Uncle Fluffy writing style. His language is so steeped in a fireside chat mentality that the meat of his ideas is completely devoured by his good-natured cleverness. He is kind of a dork (I mean that as uninsultingly as possible) and it shows. Despite his obvious grasp of a difficult subject, I can’t imagine conversing with him about it. His anecdotal asides alone are enough to trigger the gag reflex. The book is written as if he is more worried about getting the reader to like him than he is about clarity in the presentation and defense of his thesis (which, I must assert again, is a marvelous thesis, indeed).
  
  What was already to me a shaky book collapses completely in the final few chapters, when Hofstadter devotes a significant portion of his efforts to refuting only tangentially related philosophical claims. In particular, his analysis of the “inverted spectrum” is not only extraneous but outright wrong. His grasp of the philosophical arguments is lacking, and he spends most of a chapter refuting thought experiments with the laws of physics. It is frustrating for an author who has been delving into abstraction for 400 pages to suddenly attack others for their abstractions. While I’m not versed in the particular philosophers he is addressing (and I don’t think he addresses anything with thoroughness), I know enough of the concept to realize immediately the fallacy of his argument. His conclusions are irrelevant because they operate within a field of study separate from the one in question. Not only that, he is mistaken on a number of his assumptions, including the foundation of his argument – that physical external stimuli cause the same internal neural reaction. The quickest way to refute this claim is with dyslexia, where a concrete word, number or shape is viewed completely differently by a dyslexic brain as compared to a normal brain. He assumes a universal nature for thought, which proven wrong quite simply, and on the abstract level the actual nature of thought is irrelevant for philosophical musings. His mixing of physics and metaphysics, especially in an important part of his book, so near the end, shattered for me much of his credibility, mainly because it is presented in the context of a petty attack against ideas he doesn’t “like.”
  
  My long refutation of this single point of Hofstadter’s should not imply that I liked the book up to this point. I was disappointed from the beginning it. It seemed like his arguments could have been made much more clearly in a shorter work and if he toned down his personality. The density of “revelations” in this book is too low for it to be worth reading.

  The purpose of this book is to explain the mystery of consciousness. He admits off the top that the concept of the mind and conscious thought is quite difficult to nail down, and probably impossible to draw a distinct line upon. Is a mosquito conscious? After all, it, like us, seems to have a will to live, and responds to environmental stimuli in ways that benefit itself. If not a mosquito, is a bee conscious? A fish? A snake? A dog?
  
  He does so by describing the mind's process of something like "infinite reflexivity". Whereas a mosquito probably only responds in very predictable and determined ways to stimulus, higher order life "reflects" on stimuli in increasing complicated and diverse ways. His epiphany came back in the 70's when he took a video camera and began shooting it directly at the TV monitor which itself was displaying the video feed, thus showing an infinite number of reflections which gradually fade to a single point. The point, I suppose, is that because of the depth and arbitrary complexity of human thought, it is difficult to define in discrete terms, although this fact does not make it any less grounded in purely scientific and reasonable terms. Perhaps the thing I learned most from this book is that consciousness can perhaps only be understood by analogy, not by a direct understanding of the physiology or via mechanical terms.
  
  The fact that he spent nearly 200 page trying to develop this metaphor, and providing multiple anecdotes illustrating the concept of the infinite and circular suggests to me that he really has no idea what consciousness is. He tries to keep his discussion purely on mathematical and scientific terms. It's clear he falls into the camp of those who believe the mind and soul are no more than complicated atomic and molecular interactions, and is doing his part to further the quest for the Holy Grail of atheists: explaining humanity in purely godless terms.
  
  The problem is that if consciousness and brain function (if that is really the essence of humanity) were truly understood, scientists should be able to program it into a computer. So far, the only noticeable advances in the field of AI have only been virtual magic tricks -- in part researchers can get computers to seem to "think" like humans (as in Deep Blue's chess victories over Garry Kasparov) for specific tasks, but such simulations only work for the specific applications for which they were programmed. This isn't really AI -- they're just essentially complicated math solutions. There has been no AI which has successfully modeled the brain and human intelligence, which can respond to abstract and arbitrary input and truly "learn".
  
  Aside from the author's utter failure to explain the essence of consciousness (I mean, really, how could you in < 400 pages?), he shows himself to be quite the arrogant scholarly type, with contempt towards those living outside his bubble. Himself a strict vegetarian for many years, he suggests meat eaters are less human than he is, because they seem not to be bothered by eating that which once represented a conscious and semi-sentient being. He even uses such eating habits to establish his own numerical scale of human consciousness -- essentially the less meat you eat, the more human you are. Um, okkk...

  After about 200 pages of reading I still was unsure what the point was supposed to be. Hoffstadter purportedly explores the nature of self-reference and consciousness, but instead, I think, spends more time pointing out through his writing how clever he is, how feeble he considers Bertrand Russell, and how much of a fan boy he (Hoffstadter) is of Godel. It's not at all clear to me that this book has any genuine insights to offer, but that may be that it is lost on me as I find his writing style clear, but amateurish... It is difficult to get into the book for the following reasons: (a) he subdivides each chapter into 10-20 sections, each with it's own header--this serves to state what he is about to tell you, but in far fewer words, and in a way that illustrates his wit (we get it, you're very clever); it also makes reading it difficult to maintain because it breaks up the flow of the read... (b) he spends far too much time explaining extravagant thought experiments that are meant to clarify concepts that are already pretty clear... (c) he spends much of the book making one of the most impressive feats of 20th century logic (Principia Mathematica) sound like the musings of a feeble old lunatic... and (d) he does not really ever say anything.
  These things together make the book uninteresting and no fun to read.

  I read Hofstadter's "Gödel, Escher, Bach" many years ago and was completely taken aback by the author's brilliant style and insight.
  
  I read Hofstadter's "Metamagical Themas" many years ago and was fascinated by the author's vast area of expertise.
  
  I read Hofstadter's "Le Ton Beau de Marot" a few years ago and was amazed by the author's enormous knowledge.
  
  I just finished Hofstadter's "I Am a Strange Loop" and was thoroughly disappointed.
  
  The author uses 300+ pages to say something that could just as easily have been said in 100. This means that he repeats himself over and over again. And he doesn't really get to the point until about 50 pages before the end. Finally, I find his point ("consciousness is a hallucination hallucinated by a hallucination") useless and downright wrong.
  
  Waste your time on something else.

  There really is no valid reason I could recommend this book. It would be the rare reader who is interested in this topic who hasn’t read about all the classical Philosophy of Mind thought experiments presented throughout this book, and I really would have to ask any such reader: ‘what did you learn about consciousness that you didn’t already know and is meaning about meaning really that elusive to you?”.
  
  After Godel the firm foundation of mathematics as an absolute truth about knowledge outside ourselves has been seen as a chimera. Logic will only preserve truth and never creates truth outside of itself and within its own logical system needs set theory to get from the rules of thought to mathematics and by doing that you will have incompleteness and won’t be able to prove consistency. Anytime you have a system with rules a statement about the rules, a meta-statement can be made about those rules and that will lead to a recursive, self-referential, existence of a ‘strange loop’, or as in the case for being human, the ‘I’.
  
  The author invokes Bertrand Russell and Principia Mathematica frequently. The single most tone deaf introduction I have ever read was Russell’s for Wittgenstein’s Tractatus Logico-Philosophicus. Russell didn’t quite comprehend that Wittgenstein eviscerates his (and Whitehead’s) ‘firm foundations’ for mathematics through grammar and tone deafly condescendingly patronizes Wittgenstein’s understanding of the absolute foundation of mathematical certainty. There is a reason why the trivium for the seven liberal arts consists of grammar, logic and rhetoric. Wittgenstein uses grammar to demonstrate the strange loop we live in, Godel comes along a few years later and uses logic to show the strange loop and Hofstadter uses Godel’s Incompleteness with rhetorical finesse. I don’t think Hofstadter mentions Wittgenstein (if he does, it was only in passing) at all in this book and that to me seems an oversight given the similar story both rhetorically tell, one through grammar the other through logic.
  
  The author does move around a lot in the story telling and will tend to conflate ‘I’ with ‘self aware’ with ‘consciousnesses or ‘conscience’ or ‘thinking’ or other such labels. He definitely has an ‘intentionality’ way ingrained in his methodology such that thought is always ‘about something’ such as about our hope, fears, desires or wants and gives predominance to the ‘why’ of our thought over the ‘what’ was done. He’ll make ‘Being’ as thinking as in ‘I think, therefore I am’, the cogito is really saying thinking=being (that is being is not becoming, nor knowledge, nor truth, nor striving (conatus), nor will, nor will to power, but thinking), the author will make it an implied ‘we’ for the ‘I’ and therefore his cogito would be ‘we think, therefore we are’ because ‘I’ is a label for the ‘we’ that comes about through our strange loop within us. (The author says he’s not a dualist, but he does lapse into that pattern from time to time). What he is trying to get at overall requires various discussions on free will, identity, qualia, zombies, and Star Trek transporters and he makes multiple forays into those overly familiar Philosophy of Mind topics.
  
  Gadamer in ‘Truth and Method’ said, "All understanding is interpretation. Being that can be understood is language". Gadamer is the last of the phenomenologist and hence he too would have an intentionalist stance and would think that thought (consciousness) is always about something such as our hope, fears, desires, or wants. Gadamer’s quote is another way of saying we are a strange loop. Hofstadter and Gadamer accept free will as a given, but I tend to agree with Hume and Schopenhauer who both would say that we understand our desire but we don’t control the desires of our desires it just happens through our experiences and through a long series of cause and effects; understanding that we are a strange loop doesn’t change that we are captive creatures of all of our previous environments, our present presence and our expectations for the future which are filtered and weighted by our past experiences and previous environments (see, we are a strange loop!) .
  
  Our ‘I’ that we have is a label that we put onto ourselves in order get a handle on how to deal with the outside world. It’s an illusion. (I tend to agree with that, and that is the author’s thrust too). He’ll conflate the consciousness with the ‘I’. The one thing with certainty one knows about ‘consciousness’ is that it can’t be an illusion since the definition of illusion needs a consciousness in order to exist, see ‘The Darker the Night, the Brighter the Stars: A Neuropsychologist's Odyssey through Consciousness’ by Broks. That book is better than this book in almost every way. Both books authors are dealing with a loss of a loved one and are searching for meaning and the meta-meaning that automatically generates from any system that has meaning (we are always in a strange loop referencing recursively leading to a paradox of existence or in other words what Kierkegaard said, ‘Irony is jealous of authenticity’. It’s well worth reading Kierkegaard just for being able to unpack what he meant by that statement).
  
  I think Hegel in ‘Phenomenology of Mind’ understands the strange loop that is within our own minds, between me and another, and between us and them, then the author was able to explain in this book. Hegel has a beautiful philosophical dialectic giving existence to the self through the acceptance of the other and the negation of that acceptance and so on with us and between us and within our nation as a whole. This author through his methodology reaches similar conclusions (except for the national part) by leveraging off of his mostly one dimensional strange loop formulation. It seems to me Hegel explains our strange loop with more pizzazz, but obviously by not appealing to Godel. Wittgenstein doesn’t have the mathematical logic but he does have the grammar and his core belief is we live in a strange loop such that the ‘finite will never understand the infinite’ and our labels we assign are at most part of our language games and ‘the world is made up of facts’ through our experiences of the world (the second line in the Tractatus is ‘The world is the totality of facts, not of things.’).
  
  I don’t think one lives on within us when one dies as the author says. I think when one dies one is dead. Symbols of another that float in our minds as representations of an idea are just that, ‘symbols in our own mind’, calling them symbols or part of a strange loop don’t make them real outside of our own mind. Also, I think there is always a gap between humans such that no matter how close we try to get to another we can never be thought of as one (no matter how many twin thought experiments are told such as by this author) because that is part of the human experience and our meaning comes from closing that gap, and our meaning comes from remembering loved ones who have passed on and the gap between anything that is not me is a chasm that only by pretending to know what is true but is not could allow it to be falsely broached; even within myself I never know myself, and the dumbest advice of all is ‘just be yourself’ because the self is just as elusive to ourselves as others would be to ourselves. The author gives existence to the dead and closes the gap within ourselves and between others more than I think is warranted.
  
  The author takes a long time to explain what he is getting at and the story is better told elsewhere. The meaning about meaning that Hofstadter tells the reader is universal and is already part of the human experience and is told more succinctly in other books. I don’t dislike this book, Hegel, Wittgenstein, Gadamer, et al. had already demonstrated that ‘I am a strange loop’ using different methodologies, and the Philosophy of Mind standard tropes provided in this book just seem too overly familiar for my taste without adding anything new.

  The parts I liked were great, were what literature is for, really. Intellectual musings based on personal experience. Fascinating to hear about Hofstadter going through the loss of his wife. Easier to understand than Godel, Escher, Bach, especially if you read that one first.
  
  It is so awesome that Hofstadter is celebrated for/is allowed to/has made a career out of following the conclusions of his passions, making previously unforeseen connections. Ultimately I think it's an empty meditation, but a beautiful one all the same. Every now and then, we humans, despite knowing we won't come to any definite conclusion, need to sit back and wonder what it all means, in a new way each time. Hofstadter provides one of these ways. It was so cool to hear him unashamedly demonstrate his passions for the rigorous and logical study of mathematics and then discuss the definition of a soul and how we live in many people, live on in others to some extent, that this offers some consolation when people pass.
  
  It reminded me of something I was thinking hard about last year. It's no secret that I love DFW's book
  Oblivion—many of my reviews attest to that. Anyways, there's a story in it called The Soul is Not a Smithy, referencing the quote in Joyce's Portrait of an Artist...:
  "Welcome, O life! I go to encounter for the millionth time the reality of experience and to forge in the smithy of my soul the uncreated conscience of my race.”
  DFW is saying, no, you can't do this, that the tragedy of human existence is that we are trapped in our own heads.
  Since his background was philosophy, he's been trained, I think, to argue for a particular side of a debate even although there isn't enough evidence available in the universe to ever prove it one way or another. So in one respect what DFW is saying is true, but in another, Hofstadter says 'True, but you can't deny the way we live in other people's thoughts, influence their decisions.'
  
  I'm very proud to think of myself as a test for my loved ones. It seems despite all my own follies, most people I know respect me way more highly than I think I deserve (this is just a fact, not a boast. Whatever. Why am I defending myself to you? I don't know you, I'm basically writing this for my own understanding and I offer you all these words for free!) Anyways to get the full picture of my own family and friends I often have to ask around and hear things secondhand because whatever someone disapproves of that they're doing, they don't tell me! That's at least the clearest evidence I've ever found that when I'm not around, I have a certain influence in people's heads, that they ask what I would do or think. My boss said that whatever people say about you when you're not around is your reputation. I've done nothing overt to make myself so scary. But if I make people want to be better, I love it.
  
  So in conclusion: I believe the soul is a smithy, albeit an imperfect one, because I've seen evidence of it. Sure, I can't prove it, but I'm glad for that, because maybe we were never meant to. Maybe, in the face of existence, we were mercifully left to choose the happier philosophical position. So why wouldn't you?! And should I get hit by a bus today, with these words I am with you now. The only immortality we get is pseudo, but we do get it. And that's pretty damn cool :)

  This is merely a re-hash of Hofstadter's justly famous Godel, Escher, Bach: An Eternal Golden Braid, with some ideas from Le Ton Beau de Marot thrown in but most of the fun stuff taken out; if you've read those, you don't need to read this. If you've only read GEB, then read this instead of Le Ton Beau de Marot unless you have a particular interest in the art/skill of translation.
  
  This isn't a bad book, apart from the constant use of reference to the "dear reader", it's just redundant because of the above and not nearly as much fun as GEB.
  
  Here's what it's about: minds - specifically what they are/where they come from. Hofstadter's thesis is very plausible to me, despite my disagreeing with some specific things he says. It seems like it might be scientifically testable, too. My beef with Hofstadter is that his research does not seem focused on testing what seems to be the crux axiom of his theory. I'm not sure off the top of my head to do it but Hofstadter has had since some time in the 1970s to think of a way...maybe it isn't testable after all, but if it isn't then it's just a waste of time and money.
  
  Also Hofstadter HATES mosquitos because they bite him and I think that he subconsciously believes they have no minds simply because of this!

  This book, on consciousness and what makes a human an "I," is methodical and exuberant, technical and personal. Reading it was a long, thoughtful journey. It's not an easy book. The workings of the human brain are described metaphorically (and not physiologically), and often those metaphors are mathematical. Sometimes, too, Hofstadter employs playful analogies to show how consciousness works, and how it doesn't work. (He is not a dualist; consciousness arises from physical laws and not from a kind of essence.)
  
  You can read summaries of this book elsewhere; I won't write one. What I loved about it was how challenging and yet accessible it is (if you put in the time), and how willing Hofstadter is to make it personal in ways that are really relevant. (That our ability to be friends, to have empathy and affection for others, are aspects of our higher-level consciousness, according to H., is very affirming to me.) He's a scientist, and a brilliant one, but a human, too, and he's frank about his fascination and struggles with the same knowledge.
  
  From the epilogue:
  
  "The key problem is, it seems to me, that when we try to understand what we are, we humans are doomed, as spiritual creatures in a universe of mere stuff, to eternal puzzlement about our nature. I vividly remember how, as a teen-ager reading about brains, I was forced for the first time in my life to face up to the idea that a human brain, especially my own, must be a physical structure obeying physical law... In a nutshell, our quandary is this. Either we believe that our consciousness is something other than an outcome of physical law, or we believe it is an outcome of physical law--but making either choice leads us to disturbing, perhaps even unacceptable, consequences" (357).
  
  This book unfolds in layers of concepts and insight. H. builds his argument gracefully. His attention to a reader like me, studying consciousness for first time, is thoughtful and steady. Not easy stuff, he makes learning (one model of) it possible.
  
  p.s. Buddhists, beware. He admires the "noble goal" (295), yet dismisses the possibility that the self can be dismantled.

  I love Hofstadter but the good parts of this book were a rehashing of GEB and The Mind's I, and the parts I struggled through were off the mark as believable cognitive philosophical theory.

  As reading experiences go, I'd rate this a 4-star book. It's highly repetitive and speculative; its digressions can annoy; it's cutesy (typical DH) in a way that can grate after a while; and it takes repeated pot shots at a towering intellect -- Bertrand Russell -- on whose shoulders the author un(sufficiently)self-acknowledgedly stands. (Goedel, DH's guiding muse, is rightly lionized in this and other DH books; Russell -- standing in for Whitehead as well -- is all but judged a moron for failing to have seen, in the logical edifice he built, what Goedel later saw. There's a whiff of ad hominem in this book that I found distasteful.)
  
  All that said, the idea DH develops in this book is so compelling, and so beautifully constructed, that I can only in good conscience award the book and its author 5 stars. In all my reading of the popular literature on theory of mind and consciousness, only a very few books have made me feel as though, reading them, I were seeing a bit of the veil pulled back. DH makes as persuasive a case for a non-dualistic theory of mind, and provides as convincing an account (albeit, a substantially metaphorical one) of what minds do, how selves form, and what it means to perceive as any I have come across. The jury may be out on the validity of the hypotheses and models he sets forth. I for one, however, can't help but think DH (and like-minded theorists) are onto something big.

  A bit redundant in prose, and just GEB lite when all is said and done. Not really recommended.

  I agree. He is a strange loop. The first third of this book is the Hofstadter that I expected to read - dragging me through a layperson's guide to prime numbers, squares, the Fibonacci series, Principia Mathematica and Bertrand Russell's attempt to banish paradox from mathematics, and finally, Godel's discovery of the ultimate self reflective mathematical string which shattered Russell's dreams. This was tough going, but ultimately worth it for this non-mathematician. Along the way we learned that a young Hofstadter played around with video cameras - daring to point the camera back at the TV screen to create swirling loops, endless corridors and infinite regressions.
  
  The Fibonacci series begins somewhat arbitrarily with the numbers 1 and 2. Such a series could start with any 2 numbers, but once it has started, it can go on to infinity. The swirling loops made by the self reflective video camera will only start after a movement is inserted, any movement, and once started maintains the loopy image forever - or until another movement changes it.
  
  The connection to consciousness comes through a theory of development and evolution. As brains get bigger and more complex, able to hold more and more images and symbols, a critical mass is reached and consciousness appears. Like the swirling feedback or the Fibonacci series, we don't know how it starts, but once started it is self sustaining and permanent - as long as the physical brain continues to work normally. I can see it, and believe it.
  
  Then, like the self reflective numbers and riddles that Hofsatder likes to observe and understand, he tells us about his own life, his wife and family, and the loop widens. I didn't expect this, and as Hofstadter himself worries, it is hard not to think that the sections about his family and the idea that two consciousnesses can share the same brain or many consciousnesses can share many brains, came from his own need to share his suffering, not from a need to teach us anything about consciousness. Yet, he points out that his musings on the subject predated his own personal tragedies.
  
  Hofstadter shows his imagination in Godel, Escher, Bach, and he continues to teach with creativity and imagination in this book. He is a wonderful teacher - he got me to understand - oh, how briefly - Godel's ideas and how they translate into the real world, I think! As we learn about his life, his teenage fascination with self reflective images and the meaning of life, his family, his friends, we get a more complete picture of this wonderful teacher.
  
  I don't agree with all of his conclusions about the looseness of the connection between brain and consciousness and some of his ideas about symbols and the physical structure of the brain - I don't think that the loop can escape the system in which it is created, but I applaud Hofsatder for his imagination in creating his theories and explaining them, and especially for his courage in bringing himself fully into the loop. I do have a few questions: why doesn't our consciousness reboot when we sleep or wake from a coma? How can we always wake up as the same person? How do we come back to the same loop, not a different one? And what is sleep about anyway? Why do we need to sleep? And why dream?
  
  I am a strange loop and so is Douglas Hofstadter, and so, most likely, are you.

  David Gross

  I got about three-quarters of the way through and by then it seemed like Hofstadter had completely lost the plot.
  
  He makes some bold claims about the nature of consciousness, but he doesn't use his terms and concepts rigorously enough to keep his arguments straight, and he doesn't do much work to back them up anyway.
  
  It amounts to listening to some friend who got stoned and had an amazing idea. If that friend happens to be Douglas Hofstadter, it's probably worth your while to stick around for a while, have another hit, and relax in the comfy chair. It ought to be a good ride. But don't expect much more than that.
  
  Still there's plenty of thought-provoking stuff in the earlier sections, even if much of it is a retread of material he's covered before (it's been long enough that I was ripe for reruns). While reading, you'll probably pursue some of your own lines of thought, tangent to the ideas he lays down, that are as interesting and fun as the ones he pursues.

  Twenty-eight years ago, Douglas Hofstadter published a book titled "Goedel, Escher, Bach" that earned him instant academic renown and a cultlike following. A mathematician friend recommended the book to me, and I tried mightily to read it, keeping at it more because of my admiration for my friend that for the experience of reading the book. It was either too indirect, too intricately argued, or too Germanic for me to follow, and after months of off and on attempts I finally put it aside.
  
  So why did I start out to read another Hofstadter book? I have long been interested in the nature and origin or human consciousness and sense of self, and as an irreligious materialist, the traditional explanations offered by our dominant social institutions were unsatisfactory. I bought and read "I am a strange loop" because the jacket liner began with the following: "Can a self, a soul, a consciousness, an 'I' arise out of mere matter? If it cannot, then how can you or I be here? If it can, then how can we understand this baffling emergence?" I was hooked.
  
  My favorite materialist explanation of consciousness comes from Sartre, who says that consciousness arises out of material existence and serves as a presence to the world. The essence of human consciousness is the ability to negate, to say no, to conceive alternatives (l'etre et le neant). But Sartre does not explain in any detail how this consciousness can emerge from material existence. Rather, he develops a psychology that illustrates and supports his fundamental view of human reality.
  
  The core of Hofstadter's consciousness (or self, soul, I) is the enormous capacity of the human brain for complex operations, among which are feedback loops that grow in number and sophistication until they enable the human consciousness of self, the emergence of an 'I', and our ability to conceive of or mirror others in our minds. This seems to me to be a satisfying, although not necessarily complete, analysis of the problem of human consciousness in a material universe. Hofstadter's intellectual touchstones lie in mathematics, and particularly number theory; mine are in language, grammar, linguistics.
  
  The book's method and organization lead the reader to understand and perhaps accept this huge concept in a way that I again found very frustrating -- often indirect, full of special vocabulary and game-playing, highly personal, idiosyncratic, shifting and evasive, and (I would say) self-indulgent. More difficult, I thought, than it needed to be. The book demands great patience from the reader. I found myself cursing the author for the way he circled and circled around the subject, bringing in every thought he has ever had about consciousness, and relying to a disturbing extent on his personal experience.
  
  But I'm going to forgive Hofstadter again because the book has in the end provided me with an enhanced perspective on something that interests me very much. I can also give him credit for having made a case that is certainly unpopular outside of academic circles in these days of established religion and political evangelicalism, and having made it in a way that rises above ad hominem criticism. (Indeed, given the way the book is written, it may be destined to forever fly under the Christian Right's polemical radar.) A critic could of course say that Hofstadter is mistaken in his conclusions, but there can be no doubt about the authenticity and good will of the effort he has made and the undeniability of the "factual" evidence he marshalls to support his claims.

  I've been reading "I Am A Strange Loop" by Douglas Hofstadter. The development of his theme is slow, so I read the epilogue to find out if he was coming to anything other than where he seemed to be going. The epilogue seems to be about the same as the first few chapters.
  
  I skipped around the book a little and found this intriguing discussion on page 322 called 'Two Daves.' He presents a mental experiment of two universes, identical in every detail except that universe Q has the stuff of consciousness, and universe Z (zed, zombie) is missing the stuff of consciousness. In both universes Dave talks about his possession of consciousness but in universe Z he is lying without knowing it, (sound familiar?). His next section is titled 'The Nagging Worry that One May Be a Zombie." This is a promising title but he detours into fluff on this issue and dismisses it.
  
  I would suggest that with careful work, he could learn to observe both universes in his own life and experience. I know I do. I have occasional moments of consciousness that make me aware of the long intervals of unconsciousness that I suffer.
  
  I suspect that Mr. Hofstasdter has not done the experiment, followed the procedures, practiced the practices, that allows one to approach an awareness of the Self. Yet as a scientist he must have the habit of experimental verification of results. Results have no meaning without the formula, procedure, recipe, for generating them. In the index to his book the word 'meditation' is not listed, neither is 'yoga.' On page 297 his characterization of Zen 'They resent words,...' sounds more like someone who read the lab report but didn't bother to do the experiment. I would have been surprised to find Gurdjieff listed in his index.
  See:
  www.gurdjieff-legacy.org.
  
  I look forward to reading the remainder of the book and perhaps finding a few nuggets of value. But I'm afraid it is too soon to go beyond Ayn Rand's statements of the fundamental axioms of philosophy: Existence exits, and I am conscious.
  See:
  www.aynrand.org/site/PageServer?pagen...
  
  OK, I finished Hofstatder's book months ago and I have been pondering his ideas. My final conclusion is that his book is more autobiographical than a scholarly or scientific work. I did a cursory review of the field in terms of modern western scientific writing and found several writers who published significantly better works than his on this problem of the "I."
  
  One key example is :
  The Feeling of What Happens: Body and Emotion in the Making of Consciousness by Antonio Damasio. I haven't finished this book yet, or really I haven't started it, but the result of skimming it is that this book, written 14 years before "I Am A Strange Loop" is at a much higher level than H's maudlin rendering of his senile? meanderings about Strange Loops. H should know better than to publish ideas that are half a century out of date. Or if you read Aristotle, perhaps a millennia out of date. But then again, he is a parochial computer scientist.

  The meat of this book, which uses an analogy with Godel's critique of the Principia Mathematica to explain how the concept of an "I" might be an emergent phenomenon of self referential loops in the brain, is interesting. I had a lot of issues with the structure of the argument, which was too dependent on the analogy. I think there are much better ways to make this point than by talking about math. Like, I don't know, maybe talking about BIOLOGY.
  
  The last hundred pages or so of the book annoyed me so much that I did a lot of skimming. It is basically an argument against dualism through a celebration of how we can still have souls or greatness or whatever even though we are only made of particles. Hofstadter accepts materialism but isn't comfortable in its embrace, so he ends up sounding ridiculous.

  Hofstadter, I fear, has jumped the shark. More than fifty pages into this book, he had yet to offer an intriguing idea worth pursuing this book fully through. A lot of this feels like pale egocentricism.

  - Inainte sa ma apuc de "review", am zis sa dau o tura prin "review"-urile altora. Mai bine o lasam balta.
  - De ce? Uneori gasesti inspiratie si asa poti scrie si tu ceva inteligent.
  - Ai dreptate. Insa de data asta unele recenzii m-au cam inhibat. Cel putin cele de o stea sunt atat de amanuntite, cum se iau ele de DRH ca nu le-a explicat clar si precis ce este constiinta, cand de fapt el asta si-a propus.
  - Dar de ce te gandesti astfel. Oamenii aia sunt doar dezamagiti ca nu primit o formula clara pe baza careia sa isi calculeze cantitatea de constiinta pe care o au in diverse momente ale zilei, ale lunii, ale anului.
  - Intr-adevar. Ori asa ceva nu se poate.
  - Hei, inceteaza cu banalitatile. Ce ai de zis tu despre carte.
  - Pai, este cea mai desteapta carte pe care am citit-o vreodata si pe care in mare parte am si inteles-o. Este drept, partea cu Gödel si Principia mathematica m-a chinuit mult, dar pana si acolo am inteles cat de cat.
  - Deci cine esti tu?
  - Pai cred ca sunt un sistem care se percepe pe sine insusi la nesfarsit. Doar cand dorm intra sistemul reticulat activator ascendent in actiune si bucla escheriana face o pauza. Apropos, desenul "Drawing Hands" al lui M.C.Escher este senzational.
  - Crezi ca e prea stiintifica cartea? sau prea plina de dulcegarii gen sufletul unei persoane nu se afla doar intr-o persoana, el se imprastie de-a lungul vietii si in alte capete.
  - Da, sunt niste chestii pe care le spune foarte frumos si imi par mai corecte decat supa de suflete a lui Socrate. La aceasta perspectiva asupra sufletelor nu ma gandisem.
  - Adica tu esti acum aici, scrii recenzia, dar te afli si in capul jumatatii de acasa in momentul in care isi pune problema "Alex in aceasta situatie ar zice cutare si cutare" si te afli si in capul mamei tale care ii raspunde prietenei la telefon asa cum crede ea ca ar raspunde Alex si in capul fostei colege de la Fundeni care rezolva o situatie asa cum ar fi rezolvat-o Alex.
  - Da, cam asa ceva. Pe langa toate astea, analogiile din carte sunt extrem de interesante. Am notat o gramada de citate si scriitori de citit - Derek Parfit, Dan Dennett, Hofstadter, Albert Schweitzer
  - Te pomenesti ca vrei sa il asculti si pe Bach.
  - Categoric. Bai, DRH a reusit in cartea asta sa integreze o gramada de filozofie, matematica, fizica, biochimie cu o mare doza de sentimente si ganduri subiective, totul intr-o maniera inteligibila, umoristica pe alocuri si accesibila. Povestile legate de moartea primei sotii Carol sunt impresionate. In afara de asta, nu am simtit nicaieri profesorul condescendent, limbaje de lemn sau sloganuri autistice. Ce mai, 5 stele pe bune.
  - Bagi un citat asa de incheiere?
  - Da
  Seen at its highest, most collective level, a brain is quintessentially animate and conscious. But as one gradually descends, structure by structure, from cerebrum to cortex, to column to cell to cytoplasm to protein to peptide to particle, one loses the sense of animacy more and more until, at the lowest levels, it has surely vanished entirely.
  
  the "I" is a hallucination, and yet, paradoxically, it is the most precious thing we own
  
  In the end, we self-perceiving, self-inventing, locked-in mirages are little miracles of self-reference...our very nature is such to prevent us from fully understanding its very nature...we human beings...are unpredictable self-writing poems - vague, metaphorical, ambiguous, and sometimes exceedingly beautiful

  Want to read a book where a white dude with big Nice Guy Energy talks at you for 363 pages about how he defines consciousness? Then definitely check out I Am A Strange Loop.
  
  I came really close to not finishing this book, which is rare for me. It started strong, and I was genuinely interested in the stuff about Gödel and Principia Mathematica. But in retrospect, that was just one in a whole mess of unnecessary topics
  Hofstadter talked about, seemingly to show off. He strikes me as someone who loves hearing himself talk, which is why a book that probably could have been 150 pages ended up being more than double that. Not only that, but he doesn't seem to realize that he comes across as an elitist. Like dude, we get it, you like classical music, and you've always been so moved by Bach and Prokofiev, even from a young age, and why are you bringing this up multiple times throughout the book when it has a tenuous-at-best connection to consciousness? Tell me you grew up privileged without telling me you grew up privileged.
  
  To make things worse, his central thesis was, at best, unoriginal, and at worst, not convincing. Boiled down, it basically states that consciousness arises from the human brain's ability to recognize, interpret, and categorize patterns, which ultimately leads to a sort of feedback loop where it tries to categorize itself. Or something. I don't even know, I got lost in all the-
  
  -Oh wow, I almost forgot about all the little dialogues and plays he made up! No one needed that! You wrote a dialogue between Plato and Socrates when you were a teenager and thought it warranted inclusion? That doesn't make you seem precocious, it makes you seem like an arrogant and conceited... um... loop. (He used it as the Prologue, so really, maybe it's my fault for not spotting the red flag early on.)-
  
  -lost in all the unnecessary stories and tangents. At any rate, that doesn't seem like some radical new view of consciousness.
  
  But then, around the second half of the book, when he gets into all his thoughts about his dead wife (let her rest in peace!), things start getting more difficult to believe. His thesis morphs into something about how our souls (or consciousnesses or whatever), while mostly concentrated in our own brains, are also spread out across the brains of those who are close to us. How? Because those people are able to periodically see things through our eyes or imagine how we would react to a certain joke or piece of music. This idea seems invented largely to help
  Hofstadter cope with the death of his wife, as it allows him to take comfort in the fact that her soul lives on (not in a figurative sense, which I could accept, but in a literal sense) in him and her other family and friends. I had a much more difficult time getting behind this extension of his thesis, which he does a poor job of supporting. Then he tells you he's a good Samaritan because he doesn't kill bugs (except mosquitos) and then the book is over and mostly you just feel irritated.
  
  Got carried away there. I'm just aggro because I spent so much time with this book and got so little out of it, aside from frustration. At some point, I noticed I was unconsciously pulling my hair out while I read it. Then I ran out of my own hair and had to start pulling out other people's hair. No one was happy.
  
  P. S. Am I the only one who caught this sentence in the book?
  

  "... and no one I know considers prisons to be immoral institutions per se..."

  
  I'm sorry what now?

  On the face of it, this is an interesting book. The author draws analogies between Godel's incompleteness theorem of mathematical logic and the question of the meaning of identity and consciousness. And on the plus side, at least Hofstadter's discussion of Godel was refreshingly correct technically -- it helps having had some formal mathematical training.
  
  But I found his numerous and lengthy discursions to be, for starters, only tangentially and vaguely associated with Godel incompleteness. In my view as a mathematician, the goal of a mathematical author is the pare down all the fluff surrounding a mathematical result to its bare essential -- a simple, compelling and concise demonstration is much more likely to convince. In contrast, one is more likely to come away more confused by the long series. For instance, I am afraid that many social scientists and humanities persons who, after reading this book, will think that they truly know what Godel's theorem is all about. Most likely they will not.
  
  And while perhaps some will find the long and length discursions into Hofstadter's personal life (such as the early death of his wife due to cancer) to be enlightening, I don't see that they really add anything to the objective of the book.
  
  So overall, I didn't particularly enjoy this one. Better luck next time.

  The first half of this book goes into some depth concerning Bertrand Russell's and Whitehead's Principia Mathematica, and then the work of Kurt Godel. Hofstadter has an interesting description and point of view about this area. But the later portions of the book become steeped in philosophy, and quite frankly, became a bit boring. On the other hand, I had read his book Godel, Escher, Bach long ago, and found it to be excellent.

  Po Daglasu Hofštateru su nijanse sive, nasuprot crno-belom svetu, i dalje jednodimenzionalan pogled na svet i u njegovim opisima sveta postoje i sve ostale boje, kao i njihove nijanse. Dakle, sve je mnogo šarenije nego što izgleda. Kaže da nešto može biti i tačno i netačno, kao i nešto između. Tako je, iako je njegov pogled na svet čisto materijalistički on došao do zaključka da postoji „duša“. Naravno ne „ona“ duša. Kod njega su svi pojmovi „ličnost“, „svest“, „duša“, „ja-stvo“ i slični – sinonimi.
  Svakako da se sve to odvija u mozgu; neuroni i sve oko njih su i dalje glavni. Ali za dolaženje do odgovora šta svest zapravo predstavlja treba posmatrati mozak kao celinu, kao misleću mašinu, a ne njegove delove. Pitanje je šta gura šta u mozgu, neuroni ideje ili ideje neurone? Hofštater smatra kako nema nikakvog smisla pokušavati svoditi neki pojam, neki osećaj ili sećanje na jedan jedini neuron. Postoje dva nivoa na kojima se može govoriti o svesti, prvi, niži nivo neurona i drugi viši nivo simbola, velikih apstrantnih uzoraka, koji se formiraju u mozgu kao odjek spoljašnjeg sveta. Na niskom nivou nismo svesni ideja i simbola, na visokom nivou nismo svesni biologije. Taj viši nivo je kod ovog pitanja sasvim dovoljan. Dakle, suština je u simbolima. Svest je glavni simbol (skup simbola) u svakom mozgu. Na početku života „svest“ ne postoji. Prva pojava refleksivne simboličke strukture sadrži prvu iskru „ja-stva". Taj skup simbola se gomila u mozgu u petlji oko koncepta „Ja“ i vremenom postaje sve složeniji. Ta petlja je samoreferentna, usmerena sama na sebe. Ona evoluira, što čini da danas moje „Ja“ nije isto kao ono od juče a još manje ono od pre godinu dana. Ono što čini ovu petlju čudnovatom je to što taj skup simbola postaje sve komplikovaniji ali i dalje ostaje na neki način konstantan što čini da iluzija identiteta ostaje trajna.
  Knjiga ima veliki deo koji se bavi matematičkom logikom, konkretno opisuje postupak kojim je Kurt Gedel dokazao svoju prvu teoremu o nepotpunosti. Razlog za to je što Hofštater u Gedelovom pozivanju matematike na samu sebe vidi primer i dokaz da samoreferentne petlje postoje. Ono što razlikuje našu čudnovatu petlju od ostalih je percepcija. Percepcija znači kategorizacija. Što je kategorizacija jača to će i ličnost biti ostvarenija i bogatija. Što je slabija kategorizacija, ličnost je manja, što znači da je u početku života nema.
  Zanimljivo je što Hofštater tvrdi kako petlja „Ja“ nije jedina u našem mozgu. Takođe, naš mozak poseduje i tuđe „Ja“ petlje. Tako, ona pesnička tvrdnja da ljudi žive dok žive sećanja na njih za Hofštatera važi bukvalno. Ne postoji apsolutna i temeljna razlika između onoga čega se sećam kao vlastitih doživljaja i onoga čega se sećam iz pričanja drugih ljudi. Jedini razlog zašto vaša ličnost najjače postoji u vašem mozgu jeste taj što je vaš mozak prošao kroz ista iskustva kao i vi. Tuđe "Ja" u mom mozgu je samo snimljena u nižoj rezoluciji, sa manje detalja. Empatija je dokaz da živimo tuđe živote u svojoj glavi. Čak i likovi iz romana koje sam pročitao takođe na neki način imaju svoje "Ja" u mom mozgu. Ali naša se svest razlikuje od lika u romanu po tome što uključuje svest o samoj sebi. To je suština duše.
  Duša, odnosno svest, jeste nematerijalna u smislu da je ona samo mit, ne postoji. Svest je stvarna samo onoliko koliko i duga. Ličnost je informacija, skup simbola koji se gomilaju s godinama, mozak je samo medij. Možda će nekada postojati i drugi mediji.
  
  Prednost ove knjige kao i njena mana su mnogobrojne metafore. To olakšava čitanje nama laicima ali često se daje preteran broj različitih metafora za istu pojavu, ili za nešto što je samo po sebi jasno. A tek nabrajanja... Ovo je dobra knjiga za one koji nimalo nisu upućeni u tematiku.
  Iako su neke ideje i metafore koje ih opisuju nategnute, za iznesene ideje dajem četiri zvezdice, ali zbog prekomplikovanog (ili možda prejednostavnog) izlaganja, kao i zbog toga što su mu svi dokazi anegdotalni, konačno dajem tri zvezdice. Osim metafora iznosi malo dokaza za svoje pretpostavke, uz neke krajnje olake kvalifikacije. Kad malo bolje razmislim, šta sam ja uopšte očekivao, ovo je filozofska knjiga. Uprkos tome većina (sva?) razmišljanja deluje uverljivo. Ovu knjigu vredi pročitati.

  I read Godel, Escher and Bach and Metamagical Themas when I was in college, and was looking forward to a new book from Douglas Hofstadter, but this book was very disappointing. I tried to finish it, and kept reading hoping to finally come up with something redeeming about this book, but in the end I put it down around page 200. Too many thought experiments that I thought sounded just a little to simple, and nothing new if you have already read his two prior books. I also didn't think much of the reasoning that he starts to give about me living on in other people after you are gone. This may make relatives of dead people happy, but I don't believe that it will make people dying feel better. Overall, a very disappointing book.
