    Ray Kurzweil's presentation at the 2010 H+ Summit [1] was largely a mix and mash of his talks from the past 5 years.  I had hoped he would give some insight into his upcoming book on how to reverse engineer the mind, but on the subject of the mind he just repeated old stuff from his 5-year-old book.  (And his mention of "new" theories of consciousness like Penrose's quantum consciousness theories were not even new in 2005, let alone 2010.)

    As far as consciousness, he reiterated chapter 7 ("Ich bin ein Singularitarian") from The Singularity is Near [2].  According to chapter 7: "There exists no objective test that can conclusively determine its [consciousness] presence."

    Kurzweil states we are stuck at one level (neurological) of measuring correlates objectively, and "we cannot penetrate to the core of subjective experience through objective measurement."

    It seems that Kurzweil is in a phenomenological path, not for the whole mind, but at least for consciousness.  According to Paul Churchland's introductory book, Matter and Consciousness [3], "Many suppose that, through scientific research, the mind can make conceptual progress: toward the goal of reconceiving the material world, and the mind, in conceptual terms that do correspond at last to the true nature of things-in-themselves.  This is the hope of scientific realism..."

    Whereas for Phenomenology: "its various advocates are all agree that a true understanding of the nature of mind can be achieved only by methods that are radically different from those that guide science generally...They are keenly aware, as are almost all philosophers since the work of Kant, that the world-of-our-experience is in large measure a constructed world...Standard scientific activity, on their view, is just a continuation of certain of these 'constructive' activities of the mind" [3].

    The phenomenologist path, while important, doesn't seem like a very fruitful set of commitments for making progress.  Especially since one of their hopeful methods, which is to use the "special access" the mind might have to itself in order comprehend the truth, is not special knowledge at all if all knowledge is conceptual construction.

    Given his influence, I pose the question, should Kurzweil be taking this phenomenologist stance?  Why doesn't he encourage scientific research into consciousness (and how to recognize it)?  If he's a patternist, why can't he imagine definitions of patterns for consciousness and imagine engineering pattern recognizers for that?

    Hello!

    I have played with a lot of ideas on that topic and I would tell one, which is specifically non-scientific. I mean, I have no reason whatsoever to believe it. But I like the idea.

    At first: http://www.alchemylab.com/Quantum_Will.htm - this is very good text about that we should take brain as quantum device and consider the possibility that it's processes do not have to follow the laws we usually know at macrolevel.

    I have thought about it for a while, but I have such considerations behind that:
    • Lets suppose, for an instance, that consciousness is similar to descriptions of "soul" in older texts. Starting from this hypothese we can follow a few paths. As a mind game, I tried one and here is what results...
    • Lets suppose that soul is undividable. Thus it must be a particle.
    • What kind of particle? We know that particles have complex movements in quantum physics and that they basically make up a field, which shows up a high level of "awareness" about what is happening inside it's field (like jumping through the wall).
    • Particles, as I know from some popular physics book, can grow into extremely energized - faster, stronger, possibly more intelligent (if their field gets stronger, this follows from this "awareness" inside their field).
    • Particles, as we know, make up a field. Particles - for example, electrons - inside an atom make up a simple field, which is detectable. More intelligent particle might move in more complex trajectories, filling a bigger area of space.
    Thus, the play is - consciousness is usually taken as many particles, but why not to consider, that it might be one particle? One particle, which is aware of it's field, which is located at brain and/or body. I would not bet on it, but I think it's worth a consideration.

    It doesn't matter if the brain does or doesn't make use of quantum effects--we have no reason at this point to need any special sauce for consciousness, intention, or other aspects of the human mind.  It's information, with different organizations and structures at each level. 

    You don't need to understand the physics of transistors in order to use Photoshop.  Also, if you want to build a skyscraper, you will never get it done with individual grains of sand.

    As for your non-scientific bullet points, you can make whatever arbitrary definition and metaphors for consciousness you want, but it does not help anything.  Consciousness could also be a hairball ejected from the cosmic cat in the sky, which is subject to the characteristics of hair and will thus become more aware the more you shampoo it, but there's no evidence or rationale to use this fantasy.

    I made similar points yesterday to that fellow.   Your way was funnier.

    Yes, that is why I didn't write a post on that topic, but only a comment.

    Anyway, about those quantum effects - this is not actually so. Quantum effects are much more mad than classical mechanics - particles can do calculations and moves unallowed by them. To state that we should consider taking brain as quantum device - as in the text I liked - is actually to state that we should remove any limitations from how we describe brain activities.

    I can actually see the strong reason behind taking such hypotheses into account. They wont explain events, but they will raise our degree of freedom.

    Lets make an example. In case you say that the quantum will text is true, you can take three things as believable:
    1. All kinds of quantum entanglement effects can be freely used to explain things in brain - moreover, if experiments show that brain contains effects not possible in systems without entanglement, you don't have to consider them an error.
    2. Your fantasy can contain things not directly measureable as brain processes - in case your brain was classical mechanics device, it should be measureable; in case it's quantum, there may be layers of information, which are considered as non-measureable in quantum theory, but still part of your mindstate.
    3. It might turn out that there are interactions between non-measureable processes.
    And making those points clear, a lot of currently somewhat unbelievable claims in different fields of psychology become easily believable. Thus it's naive to say that this wont change anything if we take more hypotheses into account; this totally wholly changes what we are looking for and what seems possible. I would say that those, who are researching brain as classical mechanics device, for example (and there are even such kind of people really existing, I must add) - they will probably be totally unable to even consider those possibilities, which make up our actual reality. And if they wont consider those things, what they are left, are misconceptions - they are testing a bunch of misconceptions against each others. And this, I would say, is not a good way to do science. So, this is important to take all hypotheses into consideration and say that they are possible - in such case we have wide framework allowing us to take all kinds of facts into consideration.
    I like your article, Samuel. It covers a topic that is of great interest to me. I only wish, as you, that Ray Kurzweil had talked a least a little about his upcoming book on how to reverse engineer the mind. Oh well, I guess we'll just have to wait until the book comes out. Thanks for posting. ;-)

    Due to S. Hameroff PR talent or whatever, consciousness = quantum became a common sense, which is quite funny. Fortunately, there are other approaches to explain consciousness besides of quantum. Such theories as Information Integration Theory by Tononi (2008) or Global Neuronal Workspace by Dehaene are as well scientifically sound and respected among researchers. And they only require neurobiology to explain consciousness, not involving any weird stuff!
    IIT even has formulas to measure the amount of consciousness in given system... these formulas can help us crack the "neural code" at some point in future (details are in my talk at the Humanity+ Summit 2010 ;)
    heelium
    This is all nice ..sound. A nice sound :)

    For me, there are two kinds of scientific stuff:
    • Theories
    • Hypotheses

    This is easy to forget their differences, but there is one for sure - hypotheses are those, which are told to explain something "at some point in future".

    Hypotheses are usually far more powerful things than theories - a big number of them is told to explain absolutely everything. This is another sign of a hypothesis - you are told it that it explains absolutely everything, but you don't actually have absolutely everything explained. This combination of things is a clear sign of a hypothesis.

    There is also a simple logic:
    Question 1: do you have absolutely everything explained?
    In case of no, there comes a deduction: absolutely everything, which explains absolutely everything, must be a hypothesis.

    And it's even broader - in case you have read a bunch of works, you will have a bunch of things explained (otherwise you are completely lost into hypotheses). Now, when you have got the material, you can be sure - if something is told to explain something, but it does not, then it is, in fact, a hypotheses.

    Most hypotheses have defenders. Defenders like to call hypotheses an "unfinished theories" - and usually there is some theory hidden to a hypothesis, which effectively blinds some people to notice, that the rest is a hypothesis.

    Thus, I can say, you are a defender of a hypothesis. Your hypothesis might not be wrong - theories almost always start as hypothesis -, but you should not forget the fact that it's a hypothesis. Otherwise you are assigning phrases as "weird stuff" to other hypothesis - because they seem too complex, odd or not understandable by you - and you are telling that there is, "fortunately", also your hypotheses.

    Fortunately there are different hypothesis about things we don't know - and unfortunately we can not be quite sure that some of them is going to actually explain things.

    I am personally a fan of a conception called "metahypothesis". This is a kind of beast, which allows you to defend a lot of hypothesis at the same time without clinging to belief. I did write an entry about metahypothesis: http://www.scientificblogging.com/paradigm_shift/blog/what_metahypothesis ...enjoy ;)

    Okay, so let's explain consciousness by Flying Spaghetti Monster hypothesis. Sounds stupid? Probably that's because we humans are too limited in our thinking abilities to understand such an advanced concept!


    What you're trying to do is to make all thinkable hypotheses equal. That's not correct. Yes, none of hypotheses/theories about consciousness is completely justified yet. This, however, does not make them all equally possible. And it does not mean we cannot already compare plausibility of different hypotheses.

    Can you explain it into a bit more detail? I haven't heard about a Flying Spaghetti Monster hypothesis of consciousness.

    Do you know, "plausibility" is such a subjective word that it's hardly justified in scientific speak.

    There was a definition of "plausibility" in dictionary:
    1. Seemingly or apparently valid, likely, or acceptable; credible: a plausible excuse.
    2. Giving a deceptive impression of truth or reliability.
    3. Disingenuously smooth; fast-talking: "Ambitious, unscrupulous, energetic, ... and plausible,a political gladiator, ready for a 'set-to' in any crowd"

    This, indeed, shows that a theory is as more plausible as more believers it has. It is not plausible, it has no believers. I think that Spaghetti Monster theory is, thus, much less plausible than quantum theory.
    ringo-ring
    Information about Spaghetti Monster you can find in Google.
    Regarding "plausibility", it was used in its first, direct meaning:
    1. Seemingly or apparently valid, likely, or acceptable; credible: a plausible excuse.

    Hope everything is clear for you now.
    heelium
    You can not use the argument that it is "seemingly valid" against someone, to who this seems differently. If you say that it seems so, then it's not scientific.
    ringo-ring
    By "plausible" or "seems valid" I mean "supported by facts, logic, and common sense"
    of course I do not mean "supported by some strange quiet voice in your head" or by "gut feeling"
    Is this scientific? I don't care - at least it makes sense. More sense than claiming all hypotheses Spaghetti Monster included are created equal.
    heelium
    What is the probability calculus here? How it is calculated? What is taken into consideration? Are you sure you take more into consideration others do?

    And, this Spaghetti Monster - I can tell you it's quite not probable claim. Mainly because it's created to be false; theories created to be true have more chance. For example - between the knowledge that physics is quantum and brain is physics I see the simplest connection. Tell me it as short about Spaghetti Monster? How you prove it? What makes it as plausible as quantum theory?
    heelium
    I thought more of it and - these ideas of "plausibility" and "spaghetti monster" are not even slightly related to topic.

    I have thought for some time one more possibility - maybe your consciousness is fully explainable in therms of classical mechanics and mine is not? I mean - seriously. Maybe everything you consciously do and everything you are able to mirrorreflect fits ideally to classical mechanics at the same time when my brain works on different model?

    I have actually one specific reason to believe so - for me, quantum theory is not "weird". I mean, quantum theory of physics. It's pretty much reasonable.

    But if for you it is => you are using classical mechanics as basis of thinking => your thinking fits into model of classical mechanics => your consciousness (which, as you say, is additionally fully explainable by events happening in it) is fully explainable in terms of classical mechanics. I mean - there is no other logic inside. q.e.d :P
    ringo-ring
    Yes, you're right as usual. Forgive me for being so stupid.
    heelium
    Mine was a half-joke and half-truth. So right as usual.

    I wont forgive you if your device is used at wrong hands. I deeply think, actually, that people creating brain implants should try to achieve the highest levels of spiritual intelligence.

    And, by the way - I am sure that everything you are aware of is described in terms of mechanics. But you can't be so sure that you, at age x, have all the data deep self-reflectors have at age x*3. Other people might have more data. They do. And I forgive you having less data and totally urge you to be sceptical about data you cant check and find all usable correlations in data you can. This is a course of science - the specialization.

    So, have a happy researching and nice discoveries ;)
    ringo-ring
    Yes, the problem is that I have less data and less time to waffle than some deep self-reflectors ;)

    And, I didn't want to say anything about plausibility of any particular theory about consciousness: quantum, IIT, GNW or etc. Just to mention the power of PR: now, in common sense, consciousness is quantum. It does not matter that it is just a hypothesis yet without a proof. It does not matter that there are other, much less weird approaches to explain consciousness exist. But consciousness is quantum. PR is power. Funny

    I think you might have problems with self-control in such case. Just irritating ;

    So, some people say they can not explain things without saying it's quantum, you say you can. I am not positioning myself against you here - I am very interested in seeing, how far your theory goes -, but I would mention a few things, which put me into doubt of deepness of your insight and self-reflection capabilities necessary to explain everything:
    A lot of brain activity occurs without any consciousness. Even creative thinking – we are only aware of that “Aha!” moment, when the right solution suddenly pops into mind, but not conscious of all the hard work behind. But consciousness is what makes life interesting in the end.
    New technologies can make it even more interesting by improving and expanding this conscious experience.
    I am a freak of creativity technologies and thus I have worked on that aspect. I am used an old technology called "za-zen" specifically to become more aware about this process; this, actually, has resulted in me seeing things, which make quantum theory much more plausible for me.
    Such implant will create its own qualia, additionally to those we have. That means it will create some parts of consciousness artificially.
    Our task is to make electronic chip access and modify consciousness directly.
    So, this is your task. Anyway - even if you succeed, it wont show that what you achieved is consciousness; it only shows that you achieved a few qualia. In case of having consciousness field - electromagnetic field is suspect for many - you simply add some new patterns, but this does not necessarily mean that what you have created would have consciousness in itself.
    Such attempts are already being made. Researchers have built neural networks that have some properties of consciousness to test their theories. The most advanced and interesting from these developments are so-called “brain-based devices” – robots by Gerald Edelman.
    Here we have a huge misunderstanding between different parties. I have written a text specifically to target that idea - http://www.scientificblogging.com/paradigm_shift/blog/paradigm_shift_absurdity_mechanical_world_view ...from my text it results that whatever you can create in robot, is not having an experience. We have the big difference in words - you measure consciousness by activity whereas I would say it occurs also in coma, for example. Or, furthermore, the patterns of activity are not consciousness themselves - this Kantian err, which I refer, puts people into thinking that when they simulate something like Eiffel tower in computer, then they are having a real matter of Eiffel tower - metaphorically speaking. If you take rabbit from hat, you cant deceive me that it wasn't somewhere before; when you separate talking head from body, I consider that illusion - illusions exist. When my computer shows some signs of consciousness, it can't deceive me.


    I am very much interested in brain-computer connections (although I was more interested in it some ten years ago, when I did not have so much life experience), but I think you are messing up different conceptions. You are thinking that consciousness is mathematical model - it's measuring fallacy as I would call it. You think that if you measure some activities in brain and then similar activities in some other system, their conscious experience must be the same. It's not. And I am targeting this fallacy in text i linked.
    ringo-ring
    I think you might have problems with self-control in such case. Just irritating ;
    Well, you're irritated and you try to offend me. As emotions become involved it is better to close the discussion.
    But let me answer you the last time (be careful - when you discover you're wrong it can hurt you feelings)


    So, some people say they can not explain things without saying it's quantum, you say you can


    Well, this is not "me" who can do this, but the whole scientific community who are really involved in studiyng consciousness.


     I am not positioning myself against you here - I am very interested in seeing, how far your theory goes


    Again, nowhere I proposed my own theory of consciousness. I just informed you about the recent research and developments in the field of scientific study of consciousness.


    which put me into doubt of deepness of your insight and self-reflection capabilities necessary to explain everything:


    Where do I claim I explain everything?
    There are many cases I read/heard about when creativity thinking occuring unconsciously. If this process is conscious for you, well I'm happy for you. Any way, this is just an example. I could provide purely scientifically-based examples of unconscious neural activity - e.g. priming, binocular rivalry - but I put that one with creativity as most interesting.


     it wont show that what you achieved is consciousness; it only shows that you achieved a few qualia


    Well, qualia assumes conscious experience (look the definition for "qualia" in wiki) so for me this would be enough. At least at the beginning ;)


    You are thinking that consciousness is mathematical model - it's measuring fallacy as I would call it.


    No, I don't think consciousness itself is a mathematical model. But I think that accordingly to some theories - e.g. Tononi - it can be modeled/measured mathematically.


     You think that if you measure some activities in brain and then similar activities in some other system, their conscious experience must be the same. It's not.


    Yes, I try to follow the KISS - "Keep It Simple Stupid" principle. If we see nothing in a system that could point this system has different qualia from another system's qualia, then I won't bother making it up.
    heelium
    Well, you're irritated and you try to offend me. As emotions become involved it is better to close the discussion.
    I just humorly noted that you told first that some theory is not plausible and second that you did not want to say so. It's natural humor to say that you have problem with self-control and you should have figured the joke out. I actually added this "just irritating" clause to not offend you ;)
    Well, this is not "me" who can do this, but the whole scientific community who are really involved in studiyng consciousness.
    I rather doubt you in typical mistake to first define scientific community as those, who agree you; then say that the whole scientific community agrees in this case.

    I know good scientists, who would not.
    Well, qualia assumes conscious experience (look the definition for "qualia" in wiki) so for me this would be enough. At least at the beginning ;)
    Qualia is not consciousness, because qualia can change without you loosing consciousness. Buddha has explained this a lot - specifically to discriminate between consciousness and it's content.
    No, I don't think consciousness itself is a mathematical model. But I think that accordingly to some theories - e.g. Tononi - it can be modeled/measured mathematically.
    If you say that it can be modelled mathematically and/or created in computer, you are claiming that it is a mathematical model.
    Yes, I try to follow the KISS - "Keep It Simple Stupid" principle. If we see nothing in a system that could point this system has different qualia from another system's qualia, then I won't bother making it up.
    I thought engineers do that :P You can not keep the reality simple or stupid.

    Einstein has favorably said:
    It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.

    Oh Bishop Berkeley please,
    They are cutting down my trees.
    With a mighty chainsaw sound,
    Trees are falling all around.

    Don't you think it's rather odd,
    One of us should go tell God!

    Personally I believe consciosness is a construct (but what is doing the constructing?)

    What "I" "see" is selective attention and focus from a chaotic brain, full of seperate processes going there own way for there own reasons, only some of which get the special label of "thought"

    The unitary I is, my selective attention du jour believes (believed - will construct as the referent of the verb to believe) something of an illusion, a gloss on the phenomenology of being a lot of different things reacting to and acknowledging a lot of other things. (whatever "things" are, whatever "are" is, and the being, truth, equivocality, communication or plain oddity of "whatever" if you can question it without tautology.

    Phew! and I have not even been drinking this evening.

    Eco got it about right when he suggested there is no point to speculating as to the nature of being, because if there were no being there would be no-one there to do the speculating. We appear to be, and that is all there is to it.
