As John Casti Wrote, Finally, A Book That Really Does Explain Consciousness This Groundbreaking Work By Denmark S Leading Science Writer Draws On Psychology, Evolutionary Biology, Information Theory, And Other Disciplines To Argue Its Revolutionary Point That Consciousness Represents Only An Infinitesimal Fraction Of Our Ability To Process Information Although We Are Unaware Of It, Our Brains Sift Through And Discard Billions Of Pieces Of Data In Order To Allow Us To Understand The World Around Us In Fact, Most Of What We Call Thought Is Actually The Unconscious Discarding Of Information What Our Consciousness Rejects Constitutes The Most Valuable Part Of Ourselves, The Me That The I Draws On For Most Of Our Actions Fluent Speech, Riding A Bicycle, Anything Involving Expertise No Wonder That, In This Age Of Information, So Many Of Us Feel Empty And Dissatisfied As Engaging As It Is Insightful, This Important Book Encourages Us To Rely On What Our Instincts And Our Senses Tell Us So That We Can Better Appreciate The Richness Of Human Life

    I promised myself years ago that I d finally stop reading this sort of book, had been sticking to it pretty well just a couple of regrettable lapses during the 1990s and had fair warning about this one standing in the bookshop leafing through its pages, I spotted the word exformation a sort of counterpart of information of course yet still bought the thing anyway I think I might need professional help or Bookaholics Anonymous.You could summarise The User Illusion s thesis on a single page 1, what we call the conscious mind doesn t do any of the following it doesn t feel, dream, remember, imagine, think, decide or act all these, everything the mind does in fact, are done non consciously 2, the reason consciousness doesn t do any of these is because it doesn t exist the I and the conscious realm it seems to inhabit are an illusion analogous to the user illusion of computer terminology Now as it happens, having mulled it over for years myself, I pretty much agree with 1 although not 2 the most obvious problem with this thesis, though, is that you can t publish a book only one page long, so you pad it out sorry, prepare the ground with a series of huge digressions into anything even remotely fashionable at the time information theory, Godel s Theorem, chaos, fractals, Julian Jaynes, left versus right cerebral hemispheres, some nice optical illusion drawings you ve seen a hundred times beforeGaiaZeno s paradoxesWon t tell you how my head feels this morning Never again

    I found this book really hard to put down It was surprisingly one of the better written texts describing Entropy I have encountered and I felt like the writer pulled from some magnificent sources for this work It covered a broad number of fields from consciousness of course to philosophy, communism, cosmology, history, computer science and a whole host of other disciplines There were really only three main points to it which in some instances became fairly repetitive but the scope of what he was trying to convey in through these other disciplines I thought was laudable and well conceived It really made me want to pick up Julian Jaynes work which I have had on my to read shelf for awhile I thought this was really good to be honest it was a lot of good brain candy Its a completely different way to view the ego in representation to both the social community and to the unconscious me that presides over much of our actions I feel both and less of a human for the I and the Me that this body I have contains.

    Still good, still thought provoking after many years.I bought this about the time it first came out, and recently finished a re read of it.Some parts of it are a bit dated, some parts are perhaps a bit uneven, and the book is arguably as much philosophy as it is science That said, it s still a good book, good enough to definitely not deserve the 1 and 2 star ratings So, even though for me alone, it s probably closer to 4 stars, I give it a 5 star rating.That said, philosophy and science can both be provocative at times Quantum theory still is today As is general relativity As is existentialism As is the question of what is consciousness It s not a fault of Norretranders if he doesn t precisely answer that rather, today even, it s a question of can consciousness be precisely defined And, books by Dan Dennett and Steve Pinker aside, I say the answer is still no Or, at best, like Potter Stewart on pornography We know consciousness when we experience it.As for claims that the central idea is dated Tosh.Dan Wegner and others go beyond where Dennett stops and refuses to go further, and note that no Cartesian consciousness also means no Cartesian free willer This book is exactly in line with that, with the whole idea of user illusion The reader is invited to wrestle along with Norretranders as to what this all means Godel s incompleteness theorem, the recursiveness behind Mandelbrot s fractals and other ideas in the book all connect to that user illusion Yes, he could have cited Kierkegaard less, and other existentialists Yes, he comes a bit close to, though never going into, New Ageiness here and there on occasion.It s still a very good book

    This book has some really interesting stuff in it, but it was just plain a slog to read through The chapters have loads of details that are of, at best, passing interest, and it feels as though the book could have been condensed immensely I found myself zipping through other non fiction reads by comparison.If you know how to speed read or how to skim effectively then this book is a bit better of a read Things improved when I stopped trying to read every word cover to cover and just skimmed through the pages picking up the important details as I went Moreover, it is around the last hundred pages of the book where the truly interesting information is held up to this point mostly deals with the history of various scientific fields that build up to this point.Though there is a lot of interesting science in this book, it s worth noting that there s also a bit of supposition Ideas like consciousness only arising within the last few thousand years makes one wonder, if true, how it was that it did so everywhere on the globe at once Evolution would not act in that way such evolutionary traits would develop within larger regions, but clearly consciousness developed in North America, Asia, Europe, Australia the native tribes thereof , etc without any interbreeding taking place At the very least, it still holds burden of proof.That said, many of the ideas set forth do make perfect sense under today s science and knowledge, and the book contains enough of these to be than worthwhile, if you can manage to dig your way through enough of it to get at them.

    This is one of those books that makes me lose all interest in writing or saying or thinking about anything, since everything I was cooking up has already been done here.

    Tor Norretranders is Denmark s leading science writer with a track record of best sellers It follows that his book is a well written compilation of diverse scientific theories and findings, all presented in a chatty style and broken into short chapters and sections that help to keep our interest alive For anyone who reads a fair number of popular science books there are a lot of familiar names, typically well explained and often presented in an original way or with genuinely useful insights This alone is a good enough reason to read this book for pleasure For today s army of internet warriors, it will have many sharp points that help in debates on diverse topics To keep us on our toes, it also includes a few seriously defective ones which may impress the unwary, the most egregious being the very poorly supported claim that humanity first became conscious about 3,000 years ago That is one piece of spurious misinformation we must all now work to forget In addition we need to be aware that the age of his book means it has no references to MRI brain scans, which open up entirely new ways to investigate the particular phenomena he describes Science writers typically seem to go into paroxysms when trying to explain or discuss the phenomenon of consciousness They insist that the topic is enormously complex and its solution is utterly beyond our reach, the ultimate puzzle of the universe, and for this reason they throw into the basket everything they know, some of which is even relevant It provokes a tendency to mistake word games for poetry, clever twists of language for deep philosophy, geeks for creative artists On the theme of consciousness, Norretranders has his own interesting twist, which is to argue that consciousness is far less central to the way our minds function than we may imagine he virtually suggests that our conscious mind is a passive observer of the work done out of awareness by the unconscious mind He makes a good case but I think he is wrong he gets too lost in the sheer quantity of his material and fails to focus on the argument itself he presents mountains of evidence to support his case and fails to appreciate that it is important and useful to pay attention to the material that calls it into doubt Firstly, we have Popper s concept of scientific method to remind us that no amount of supporting evidence can outweigh evidence of being wrong Secondly, we have Norretranders own argument that a large quantity of information is no better than noise it only becomes meaningful after most of it is discarded, selectively, and reduced to a simple product of reasoning, which becomes its point or its meaning Worst of all, he tries to simplify a biological and psychological phenomenon into the language of physics and mathematics, in the form of information theory, and even his own material in this book is sufficient to tell him that this is a doomed assignment from the outset Yes it is possible to reduce consciousness for example to a simpler, physical or mathematical description, but only by throwing away most of what we know, and we cannot reconstruct consciousness from the resulting simplistic description He is just plain wrong his argument can only work to the extent that there is a conscious mind available to read and consider his argument, which already demonstrates that his argument does not work after all Some quotes from the book The interesting things in life may not be the ones that take long explanations to describe but those that take many experiences to get to know p80 A biological creature is the result of a very long evolutionary computation A yes or a no may be the result of a whole mass of hard won experience p81 The concept of information is a very bad one if it is taken at face value If you suppose that the information in information theory is about meaning, you are in for a disappointment Because it is not what we say to each other every day that establishes all the meaning and beauty and truth our everyday conversations contain it is everything we think before we speak p98 The interesting thing about words is not that they can be said but that there was something that could be said The interesting thing about speech is not how we speak but that we have something to say p106 The American anthropologist and cyberneticist Gregory Bateson wrote in 1966 As mammals we are familiar with, though largely unconscious of, the habit of communicating about our relationships Like other terrestrial mammals, we do most of our communicating on this subject by means of kinesic movement and paralinguistic signals, such as bodily movements, involuntary tensions of voluntary muscles, changes of facial expression, hesitations, shifts in tempo of speech or movement, overtones of the voice and irregularities of expression The problem is that in practice we humans do not wish to admit that we are animals We think our consciousness is identical with ourselves So we tend to believe that everything we say lies in the words We take ourselves literally We think information is the important part of a conversation p149 The insight that consciousness plays a smaller role in human life than most of us would believe may be vital because it is the only insight capable of transforming a culture that has serious viability problems p161 If all the information that thunders through our senses is merely discarded, apart from the bit we are aware of, how can we tell that the bit we are aware of is the right one p173 If consciousness selects at random from what comes in, it really is not much use There must necessarily be a degree of wisdom in the sorting that takes place otherwise we could go around conscious of something random, with no connection to what really matters p173 Consciousness is based on an enormous discarding of information and the ingenuity of consciousness consists not of the information it contains but of the information it does not contain p173 We do not see what we sense We see what we think we sense Our consciousness is presented with an interpretation, not the raw data Long before this presentation, an unconscious information processing has discarded information so that what we see is a simulation, a hypothesis, an interpretation, and we are not free to choose p187 What we experience has acquired meaning before we become conscious of it p187 The problem of other minds is closely related to the problem of the existence of the external world How can we say there even is one A Danish philosopher, Peter Zinkernagel, has solved this problem by pointing out that we cannot say there is no external reality language breaks down totally if we assert that language does not have anything to talk about But this is not proof that there are other minds or an external reality, for that matter It is merely a stating of the fact that here is a problem we cannot discuss unless you acknowledge the existence of other minds, you have nobody to talk to about this point of view of yours p196 Human consciousness possesses a high degree of complexity It is a phenomenon of considerable depth A great deal of information is discarded in its making We must therefore now ask does creating consciousness take time Does discarding most of the sensory information before we experience also take time Well, it must So the real question is how long it takes because we sense constantly and we are conscious almost all the time So if consciousness takes time, it must constantly lag behind p209 An actor has a much higher bandwidth than language does There are gestures and gesticulations, intonations, movements, glances, and charisma a series of monverbale communications which the audience perceives or less consciously Similarly, the musician does not merely deliver the score but hopes to transform it into notes that supply it with pauses, accents, phrasing and other goodies p263 The theme of psychotherapy can be formulated as the I s acceptance of the Me the acceptance of the fact that it cannot control the real subject of an act even though our entire culture tells us we can if only we try to be a bit pious and holy The point of psychotherapy for the individual is the lesson I accept my Me p271 Heidegger expressed the angst at the way the world can be freely interpreted but experienced only through interpretation the angst of the I at not being the Me p274 In The Sickness Unto Death, Kierkegaard describes the feeling of despair which comes at three levels The despair of not being conscious that one has a self the despair of not wishing to be oneself the despair at wishing to be oneself p275 The content of our consciousness is already processed and reduced, put into context Conscious experiences possess depth They have been put in context lots of information has been processed but is not presented to us A mass of sensory information has been discarded before conscious awareness occurs and this sensory information is not presented Yet the experience itself is based on the discarded information p288 We experience not the raw sensory data but a simulation of them The simulation of our sensory experiences is a hypothesis about reality This simulation is what we experience It takes time to achieve this depth There are bundles and bundles of intermediate calculations that are not relevant to our actions in the world We have to solve the binding problem before we can experience anything at all we have to form a hypothesis about where the sound came from before we hear it p289 The bandwidth of language is far lower than the bandwidth of sensation Most of what we know about the world we can never tell each other p309 The holism reductionism controversy today is a debate that may be said to be pass false opposites Actually, none of the parties to this debate had grasped the real point, which P.W.Anderson had already formulated in his slogan More is different, which originated from a lecture he gave in 1967 The ability to reduce everything to simple fundamental laws does not imply the ability to start from those laws and reconstruct the universe Anderson s point, therefore, is that reductionism does not necessarily conflict with the view that complexity exists and new natural phenomena arise every time we step up the scale and study new layers of the universe p356 The road to complexity is simple but long When simple rules are allowed to beaver away long enough in time or in a sufficient number of component parts, completely new properties appear they emerge, break out, pop up, come into view These emergent properties cannot be found by studying a small collection of component parts They can be seen only when there are so many parts that collective influences, group properties, can occur Temperature for example is a property that yields no meaning if we observe very few molecules A large number is required before temperature is present We cannot see from the individual molecules what temperature it is part of, for temperature is a collective property manifested as a statistical relation A temperature describes the distribution of velocities among lots of molecules p364 Life is an emergent property of matter, not a property of matter s component parts p385 Consciousness must make do with very few bits per second for nourishment It is like fast food There is almost nothing to digest, no bones and fibre to discard during and afterward p397

    I enjoyed every moment of this book And it was a long read The author introduces known concepts in a vivid manner and talks about them in a novel way, adds some of his own new concepts and builds it into a coherent logic, a lens you can view the world with.My favourite excerpt is the Exformation of phone call, brilliant observation, hidden in plainsight

    M rk verden af Tor N rretranders er uden tvivl blandt det bedste faglitteratur jeg har l st Af flere rsager.Vores bevidsthed er enormt facinerende i dens ubeskrivelighed I M rk Verden s tter N rretranders fokus p bevidstheden og dens foruds tning for vores oplevelse af vores eksistens, og dermed som mediet hvorigennem vi tillader os selv at m rke verden p godt og ondt.N rretranders skriver i et samlet og flydende sprog, hvor der veksles fint imellem faglitter re og l gmands termer, hvilket er med til at tr kke stoffet ned hvor det skal bruges, i ganske almindelige liv hjemme i sofaen, i k en i Netto, p skovture med familien osv Og det er en v sentlig bedrift, for i sin beretning om bevidsthed tr kkes p tunge videnskabelige erfaringer, som kr ver sin vidensskabsjournalist at t mme.Det form r N rretranders rigtig godt og han n r oven i k bet ud i rigtig mange videnskabelige kroge p jagt efter begreber, der p smuk vis gennem bogen bruges til at beskrive den ellers s ubeskrivelige bevidsthed Og naturligvis ogs begreber til at beskrive det ubeskrivelige ved bevidsthed osv Bogen er opdelt i 4 dele Beregning, Betydning, Bevidstehed og Besindelse Rejsen bringer dig forbi emner som termodynamik 2 lov , informations og eksformationsteori, matematikkens begr nsninger, erkendelsesteori, bevidsthedens b ndbredde, logisk dybde, perceptionsl re herunder ogs subliminal perception, neuropsykologi og godt med kaosteori Der er kildeanvisninger gennem hele bogen.Mange blive skr mt af bogens f rste del, som handler om teoretisk fysik, termodynamik, matematiske teorier og kompleksitet som begreb Jeg har h rt om flere som surt nok aldrig n r til 2 del Der er godt nok allerede i 1 del hints til hvor N rretranders vil hen med hans gennemgang af de tunge emner , men det er nok f rst til sidst i bogen, n r han er helt f rdig med at tegne sit komplekse portr t af bevidstheden, at man forh bentlig forst r sammenh ngen Og det er virkelig et betagende billede.Alt i alt, en sublim bog.
