Afterword:

It was the Casey essay that got me thinking about "How did Faraday and Maxwell visualize the problem?" My guess is that Faraday saw it as the Particle View, IIR version. As per the bible, "In the beginning..." the matter and the interconnecting "lines of force" were put into place, and then left to interact. Maxwell's much more mathematical view centered upon unchanging differential operators; since the operators cannot expand to meet the particles, the particles must somehow travel to meet the operators - hence the field.

But with my background, I tend to think of operators like tapped delay lines - the pond has dispersed tide gauges, like FIR filter taps, whose outputs can be combined to form difference operators etc. (filters), which can change over time. Tide gauges can be moved, their number changed, and the manner of interconnecting them can change.

Perhaps an analogy could be made between the expanding cosmos and the growing cortex of the brain. The whole brain grows in size, within it, neurons grow, and grow connections (lines of force) and signals (forces) are transmitted via those connections. The interactions thus have three relevant speeds; speed of brain growth, speed of neuronal connection growth, speed of interaction along established lines of force.

Rob, each of those three paragraphs is a little jewel, and together represent the reason I always look forward to communicating with you.

Oops. I missed the comment before the afterword.

I should emphasize that my field equations express mass dependence in terms of mass density, so particles and fields, at least in the early moments of the universe, are best viewed as simply different density distributions. Of course as the universe grows the field density diminishes while particle density is locked into localized distributions. Due to essentially random fluctuations in density these tend to aggregate into galaxies and galactic clusters. If, as I suppose, the global distribution remains effectively scale-invariant, then there is very little non-local change propagating, and galactic formation is viewed as local with no global significance.

So initially it is the fields causing gravity, globally. Then local "condensation" produces particles (in the expanding universe). The fields continue to weaken but the particles aggregate and produce stronger, but localized, fields. In other words the nature of the self-interaction varies until finally the most significant self-interaction is in our brains.

Which is fun!

In your particle view above, the FIR version is closest to what I imagine, but this assumes that there are signals spreading outward. If the distribution of mass does not change, as seen beyond a certain radius, then there are no signals, so there is no 'expanding colony' except in higher order approximations. But in any case, the FIR view seems more realistic.

Best,

Edwin Eugene Klingman

Edwin,

Our struggle reminds me of one of my favorite movie lines, from Clint Eastwood's "Eiger Sanction". The mountain climbers are in trouble. Clint says to one of them, "Don't worry, we'll be OK". The other responds, "I do not think so. But we shall continue in style!"

Keep up the good fight!

Rob McEachern

Hi Edwin,

I very much enjoyed your essay. You wrote:

1. "Without the physical, there simply is no information. To argue otherwise one must show how a world with no physical reality can be brought into existence from information. Wheeler's remark "how to combine bits in fantastically large numbers to obtain what we call existence" was just unsupported fantasy."

I think the question is whether what we experience as "physical" is really better understood as "virtual". Is our "physical reality" an illusion? When we look out at the world, are we just seeing an immersive virtual illusion? We have the example (or analogy) of software agents in a virtual world. What they might "perceive" as "physical" we know to be "virtual", that is, just based on information. Are we in the same position, that everything we take as "real" is virtual and the ground of being is unobservable?

2. "It's been a Participatory Universe from the beginning."

I agree that is the simplest explanation.

While yours is an elegant bottom-up explanation for the cosmos, my essay Software Cosmos takes a top-down approach. While my starting point is very different, my picture does include a hyperspherical gravito-electric field (i.e. without boundary conditions) that may provide a venue for yours. You also may like the fact that I endorse Geometric Algebra and do not require Inflation in my model. Anyway, I hope you find some food for thought or a reference or two in there that will be of use to you.

Hugh

P.S. I have a copy of your Microprocessor Systems Design (vol II) still on my bookshelf, from my days of developing operating systems for new computer hardware. Chapter 7, which describes the construction of a floating point processor, is a remarkable account of how a higher order can be constructed from simpler parts. Consider that today's virtual worlds like Second Life, while implemented in software, are reliant on decent floating point calculations. We could say that conceiving and implementing the FPU design is where the physical world opens to the possibility of hosting a virtual world. You described that transition in 62 pages that are still enjoyable today as a reminder of the ineffable pleasure of seeing such possibilities open up.

    Dear Edwin,

    Thank your for your many very interesting ideas. Here are a few comments.

    The real world is not a purely mathematical or informational entity. As I understand your essay, this is one of your main theses. I agree with this contention. For one thing, nearly all of mathematics has no relevance to the physical world. Therefore, some additional principle or fact of reality must account for actual existence. Nonetheless, you would, I think, allow that some part of mathematics is at least useful for the understanding of physical existence. Indeed, you present your theory in a mathematical way. What about the mathematics which is not physically applicable? Is that just fictional or made up? Or does it have a different kind of Platonic reality of its own? This point is to the side of your topic, and therefore you did not discuss it, but it would be interesting to know your views about it.

    I also have to agree with your insistence that awareness is a genuine feature of reality. Would you consider your position a kind of panpsychism? If awareness is a primordial property of the field, that would seem to imply that awareness, or at least proto-awareness, is everywhere.

    I am not clear about the relationship in your theory between this universal aboriginal awareness and the self-interaction which gives rise to the physical world. Are these two separate properties of the field? Two aspects of the same property? Or something else?

    Finally, your essay should remind us not to be too quick to dismiss awareness from reality altogether, based on what are thought to be the findings of physics. You propose a new system of physics, based on one field. Even those who accept some other system--such as the hundreds of fields, which you attribute to Susskind--will have to admit the force of your critique of the current state of knowledge (or current state of ignorance and belief). Given this not very satisfactory situation, do we really have adequate reason to suppose that awareness, consciousness, and thinking are something other than the way they present themselves to us?

      Dear Edwin,

      Not sure why the system posted my comments (immediately above) as anonymous. However, I signed on again, and this should attach my name to the post.

      Thanks.

      Laurence Hitterdale

      Dear Hugh,

      Thank you for your comment and your analysis. I've just read your fascinating essay and will respond (mostly) on your page, however I will say here that it seems to be one of the most serious approaches to software cosmos that I have read.

      Your ask, "is our "physical reality" an illusion?" This is of course the key question. You then ask "when we look out at the world, are we just seeing an immense virtual illusion?" and you mention 'Second Life' in your comment. Several years ago I spent some months in 'Second Life', and it is certainly a powerful example of what the last decades technology can accomplish. If one projects this to the 'ultimate' then a software cosmos seems more feasible.

      As you note in your postscript, I do have hardware and software experience, and I cannot conceive of how one produces the software without the hardware. This is the 'It from Bit' aspect that I get hung up on. For example you mention that "the implicate representation can be encoded for storage efficiency...". Storage in what? I agree, in principle, that we can compute the dynamics of the world to a degree that visually everything we see is 'virtual'. But it doesn't solve the problem of my self-awareness (at least for me it doesn't).

      I very much like your mathematical analysis based on geometric algebra, Joy's ideas, Rowlands and your other references. And you are correct that I find your references very interesting. Thanks for those, too. I'm also a fan of Doug Sweetser and reference him in an earlier essay. But I was unaware of Finkelstein's GA approach to QED. I also agree with you that fields, rather than individual particles, are more practical in the implicate.

      Finally, you ask, "if the universe is a simulation, can we detect its 'hardware'?". (Thanks for the references that address this question.) Instead, you ask "can we detect its software?", and you propose to search for "fractal creasing".

      In short, you've opened up a whole genre of research in your references. I do not believe this approach is satisfactory as an explanation of awareness, as I am aware of much besides visual input, including being directly aware of gravity. Nevertheless you've written a masterful essay that has made me aware of many new ideas and relevant resources and that's worth a 10!

      For your information, since you enjoyed my decades-old bit-slice design of a floating-point computation unit, I've recently (~2008) implemented a much improved version in an FPGA and combined this with my 'iMEM' Intelligent memory architecture, designed specifically to produce exactly the kind of dynamic calculations you write about. I did not see your email address, so please email me at klingman@geneman.com.

      Thanks for reading my essay and commenting, but most of all thanks for writing your essay and calling it to my attention.

      My best regards,

      Edwin Eugene Klingman

      Dear Laurence,

      Thanks for your comment and questions. As I noted on your page, you handle "bit as fundamental" and "universe as computer" so masterfully that the topic should be closed! Nevertheless, if you'd like to see how fascinating the "other side" can be, I recommend Hugh Matlock's essay [see comment above yours.]

      You point out a little-noted fact, that "nearly all of mathematics has no relevance to the physical world" and conclude "therefore some additional fact of reality must account for actual existence." Then you ask if I agree that math is useful for understanding physical existence, and whether it does not have a Platonic reality of its own, noting that I begin with an equation...

      My basic assumption is that the universe either began as ONE thing, from which ALL evolved, or it may as well of been created with billions of things. Once we assume more than one thing, why stop at two? And the Platonic reality of math is more than ONE thing. But further, I find that the existence of physical thresholds (which falls out of the Master equation with the quantum of action) leads to natural binary states and physical continuity (assumed in the Master equation) that leads to 'circuitry' or connections between such states that easily implement logical circuits AND, OR, XOR (COMPARE) and that such gates easily implement ADD and SUBTRACT circuitry and, as noted in Hugh Matlock's comment above, floating-point computation. Kronecker famously said "God made the integers, all else is the work of man." Since the integers derive from simple counter circuits (which can be implemented in DNA, silicon, or neurons, etc.) I find that math is a "side effect" of physical reality. In other words, physical reality instantiates 'logic', probably as a necessary consequence of self-consistent existence, and physical logic leads straight-forwardly to counters, natural numbers, and all of math. There is no reason to assume another Platonic 'realm'. I suspect this is just part of the confusion that generally surrounds consciousness.

      But math circuitry, like logical circuitry, leads to language, and just as natural language can produce fiction having only remote ties to reality, mathematical language can be untied from reality. As you note, this is why we cannot conclude that physical reality derives from math, because why just "some" math and not "all" math?

      You also agree that "awareness is a genuine feature of reality." You ask whether I would consider my position a kind of panpsychism. I guess I'd have to say it is a "kind of" panpsychism, although, as I understand it, panpsychism generally ignores relations to physical reality. So I think I'm more 'nuanced' than panpsychism, and, not having any conjecture about the 'cause' of physical reality, I leave the door open to a "higher cause".

      You further ask whether the universal aboriginal awareness and the self-interaction which gives rise to the physical world are two separate properties of the field or two aspects of the same property, or something else. First, I should note that the self-interaction does not "give rise to the physical world". I don't know what gave rise to the physical world, but I'm convinced that those who believe that mathematics (or information) can or did give rise to the physical world are badly mistaken. But since we find ourselves in (and are directly aware of) a physical world, I start with the simplest possible world, one field, and conclude that, to evolve, it could only interact with itself. There was simply nothing else to interact with!

      And I find this reasonably implies that to interact with itself the field must have "some" awareness of itself. I would probably not insist on this aspect (?) except for the fact that I have awareness of myself, and based on experience and on reasonably expert awareness of computers and biology, I don't think my awareness is an artifact. Therefore I conclude its primordial. With this assumption I find that everything I know of could reasonably have evolved from the one aboriginal field. What brought that field into existence is an ultimate mystery and will certainly never be "logically" explained.

      Your final question, whether awareness, consciousness, and thinking are something other than the way they present themselves to us, is the essence of Korzybski's dictum. They *are* the territory.

      Thanks again Laurence, for your essay and for your comment. I noted on your page weeks ago that your essay was worth a 10 but I didn't score it at the time. I've just remedied that.

      Edwin Eugene Klingman

      Laurence, my mistake. Upon attempting to rate you, I find that I already did so.

      Hi Edwin,

      Thanks for your comments and compliments. You wrote:

      > I cannot conceive of how one produces the software without the hardware.

      I agree that there has to be some kind of "hardware". But I do not think it has to be what we call "physical" (And that is what I took to be the "It" of the "It from Bit"). Of course, that means I should come up with a proposal for what kind of "hardware" is involved. I think that this is a difficult question because many kinds of hardware can generate the same software effects, as I mention in the essay.

      > I agree, in principle, that we can compute the dynamics of the world to a degree that visually everything we see is 'virtual'. But it doesn't solve the problem of my self-awareness (at least for me it doesn't).

      There are a lot of interesting issues related to awareness, and unfortunately (or fortunately!) the essay length limit prevented me getting into them. The first thing I would note is that learning and memory do not seem to depend on a physical brain. So the question is where is memory held if not in the brain?

      One advantage of the software cosmos model postulating an "unobservable hardware" basis for the physical world is that same basis can be suggested for storing our memories. In other words, if the world is virtual, then our memories could be akin to those of AI software agents that use the hardware memory rather than needing any representation in their virtual world for it.

      Of course, this suggestion really just kicks the can down the road, and inquisitive minds will want to know how the invisible hardware works...

      My hope is that figuring out the first level will give us enough clues that we can make a guess about these even more difficult questions regarding consciousness.

      Hugh

      Edwin,

      OK, so the "existence" and "changes" in this "self field" constitute what? Measures? ...they better be .... and .... then your arguments draw on other's measured data to confirm or deny your drawn conclusions. You therefore remove yourself from measures of your "self" field changes and revert to quoting data external to that measured by the "self."

      That sounds like a reductionist requirement of holistic to obtain the measured definition of ones self? If your single field explains everything from inside out, why does it require an outside -> in confirmation?

      The reason may be due to our measured reality requiring this confirmation from others, and, it is highly likely that others have an alternate approach to your self field and can match your measurable results in anything you will ever predict. This implies that many relevant, coherent, calculable paths may lead to your very same conclusions .... so who is correct?

      Until science finds the correct "context" to apply all we measure, natural breaks in coherent knowledge will inevitably result, because the next step in a GUT correlation requires a deeper understanding of the single context that all measured science operates under. This implies that everyone can be correct when viewing information in their own sub-context, and, when the universal context is eventually found and accepted, all sub-contexts can be projected onto it and commonalities will appear with differences. This implies that multi-universe theory may be one man's way of saying each of us has our own measured universe with all sub-contexts merging into the single context supporting "life" as the center of creation. Holonomic physics/CFT/Shape Dynamics/etc., your "self" field/ all may simply point to being capable of merging into a much deeper, unique context.

      It would then appear that unification requires context definition and your self field doesn't seem to fit the entire bill when it comes down to the "self" having to be "measured" by others. We know that the measurers HAVE to interject in the results of the measure and add their own personal sub-context bias.

      Best regards,

      Tony

        Dear Edwin,

        Thanks for taking the time to clarify your ideas further. I now see that you advocate a strong monism, to use a term from the history of philosophy. I am not fully convinced by your arguments. One concern is whether all mathematics and logic are also based on the One Existence, just as we ourselves and the physical world are so based. Also, the details of your system will be essential to its viability. The world around us is variegated and plural. Are all those things somehow just One Thing, or at least somehow rooted in One Thing? To argue for an answer "Yes" two lines of thought are necessary: first, explaining how the many come from the One; and second, showing that this monistic account is better than alternative explanations. As far as this contest goes, I will have to leave it at that, because the contest opens many other discussions. However, I appreciate the opportunity to become acquainted with your thinking. Perhaps I can learn more about it later in another discussion.

        Laurence Hitterdale

        Dear Laurence,

        You are more familiar with the fine points of philosophy than I, but Monism and panpsychism both seem near to what I hypothesize.

        Yes, of course the details of the system are essential to its viability. That is and has been my approach. It is not difficult to show that Newton's gravity and general relativity both can be derived from the master equation, and similarly a generalized form of Hesisenberg's uncertainty principle and a derivation of quantum mechanics as presented in my previous essay. I believe that I have a good chance of computing the masses of the known particles from basic principles, in contrast with the Standard Model. But my main focus is on the numerous anomalies that do not fit into any current theory of physics. I believe that most of these are explained by the non-linear gravitational field.

        As for math and logic, I spent decades working as a logic designer and am quite satisfied that logic and math both are derivative. But, as Smolin points out, belief in a Platonic realm of math is essentially religious, and so I do not expect to sway any believers.

        So, I am well along the process of explaining how the many come from the One, but I am unsure how to show this is 'better' than alternatives, other than to show that it explains the anomalies that others do not.

        Thanks for reading, and commenting, and I would be happy to continue this in a later discussion.

        Best,

        Edwin Eugene Klingman

        Dear Anthony,

        I'll try to respond to your comment as I interpret it. I've found in the past that even those who hold a similar view of consciousness typically require extended effort to harmonize vocabulary, since most relevant words are very fuzzy.

        You ask what "existence" and "changes" in the "self field" constitute, and conclude they better be measures. I'm confused right off the bat, but if you're saying that the theory needs to agree with others' measured data, that is certainly true. But then you seem to imply that I am after a "measured definition of one's self". This is not the way I conceive of it. I am subjectively aware of myself and this does not require either measurement or definition. Only objective "things" require measurement definition.

        And although I tend to view it, as a physicist, as the gravitational field, which possesses an inherent, if only primordial, self-awareness, it is just as valid for you to consider it a 'self' field possessing gravitational properties. But only the gravitational properties are measurable.

        As for a single field explaining everything, my hypothesis is that initially only one "thing" exists, the field. There is no 'outside' or 'inside'. As it evolves, symmetry breaks, and 'local' and 'global' acquire meaning. Any attempt to describe a holistic 'system' has to start somewhere, but this should be arbitrary, since it all must tie together.

        And yes, measured reality is required for confirmation from others, as they tend to be unenlightened and will not simply take my word for it! And, with the exception of numerous anomalies that exist, other theories can and do match my measurable results. Currently, I believe only my theory explains numerous anomalies, but this is only qualitative, so far, and I'm hoping my new n-GEM technique produces quantitative agreement. You ask "who is correct" and I suggest that how anomalies are handled will be a good test of this.

        You make some assumptions about science finding the correct "context" that indicates you've put a lot of thought into this. I'm sure I'm missing some of the subtleties of your idea. So I'll make two responses that may be off the mark. Currently Multiverses are based on certain ideas that I think I will be able to prove wrong, but I'm not sure this is related to your statement. And when you say the "self field doesn't seem to fit the entire bill when it comes down to "self" being measured by "others", you lose me. I am subjectively self-aware *and* objectively aware of others. These will, in my opinion, never fit into a scheme of the type you seem to be proposing.

        If I've completely misinterpreted your comment, please try to clarify my mistakes. And my sincere thanks for reading my essay and trying to formulate the problems as you see them. I appreciate it.

        Best regards,

        Edwin Eugene Klingman

        Hi Hugh,

        A few remarks. I'm glad you agree there has to be some kind of "hardware". I'm not sure what you have in mind when you say it doesn't have to be "physical". Of course one instruction set can simulate another instruction set and the simulation can simulate another instruction set and so on ad infinitum, but this only goes forward. There must be the original physical instruction decoder on which the whole chain is based. I'd be very interested in what you come up with in this regard.

        Yes that darn essay length limit gets in everybody's way. But you note that "learning and memory do not seem to depend on the physical brain." Could you elaborate on this.

        I'm a little confused on the "unobservable hardware" basis for storing memories in a virtual world. In the physical world, as I see it, the things themselves store the initial data ("memory") themselves. And their ongoing state keeps track of ("remembers") their current state.

        Thanks for the email, and the suggestion of geometric algebra processing hardware. We can conduct this discussion off-line.

        Best,

        Edwin Eugene Klingman

        Hi Edwin,

        > I'm not sure what you have in mind when you say it doesn't have to be "physical".

        Simply that, a simulation does not have to represent within it the "hardware" that is running the simulation. Second Life does not have to have a large server room appear inside its virtual world. (Nevertheless, there is such a server room running the simulation. )

        If the "physical world" of our senses is really virtual, then there is no necessity for the "hardware" it runs on to be in evidence. Yet it is still there, unobservable from within the simulation. If our physical bodies are like avatars in Second Life, we will search in vain within Second Life for the big server room. Yet the source of the simulation must exist.

        > Of course one instruction set can simulate another instruction set and the simulation can simulate another instruction set and so on ad infinitum, but this only goes forward. There must be the original physical instruction decoder on which the whole chain is based.

        We may have a terminological ambiguity and some resulting confusion. There are two different kinds of simulation.

        Lets call Type (1) what you describe here: One instruction set can simulate (or emulate) another one via a process of translation. The decoders for both must be of the same type (if one is physical the other is also). This is true down any chain of decoders, as you suggest.

        Type (2) simulation is when an instruction set is used in a more complicated way. It is used to model (via computational geometry) a virtual world, snapshots of which are rendered to create an illusion. In this case, the result of the simulation is of a different type from the input. Objects that appear in a movie are not the same as objects in the theatre, even if a moviegoer might get caught up in a movie and start to believe it is "real". We do not expect objects in the movie to be able to interact with objects in the theatre. So the objects that result from this kind of simulation are of a different type.

        The "orignal instruction decoder" must exist. The question is whether it should properly be called "physical". If we take the word "physical" to be what we normally take it for, the kind of stuff that tables and chairs (and our CPUs) are made of, then I argue that the decoder need not be that kind of "stuff".

        I am saying that the physical world is a Type (2) simulation not a Type (1) simulation. That is, when we look out at the physical world we form our idea of objects from observing the dancing colors on a kind of 3D display screen, just like a gamer engrossed in their game. We and our bodies are immersed in a 3D movie and do not see the "theatre" it is playing in.

        So if objects in our 3D movie are known as "physical" what shall we call the objects in the "theatre"? I used the term "unobservable hardware basis".

        Hugh

        Hi Hugh,

        I understand simulation of the two Types (except that I would not say for Type 1 that "the decoders for both must be of the same type (if one is physical the other is also)". Only the root decoder must be physical. All higher-level decoders in the chain can be 'soft'. In fact, this is almost certainly the way all new instruction sets are debugged before committing to physical hardware.

        For example, for several years in the 80s I made good money selling simulations of 8051s that ran on 80386s. The 8051s could have simulated another processor, in which case my simulated 8051 could simulate the other processor, and so forth. Only the root decoder (in this case the 80386) need be physical. [By the way, thanks for reminding me of this... one of many things in my past life that I tend to forget!]

        And I agree that one can search in vain inside of Second Life for the "big server room".

        So I agree that, in your scenario, the "unobservable hardware basis" need not be evident. Yet it must exist. You seem to agree as you say that "The 'original instruction decoder' must exist."

        And it must be "hard". That is what I mean by "physical". You seem to be saying that my idea of "hard" is an illusion I've obtained from the virtual world, yet you also seem to agree that the "original instruction decoder" must exist. If this is not in some way isomorphic to "hard" (a.k.a. "physical") then I have no idea what you can mean by this.

        Is that what you meant when you said in an earlier comment that "learning and memory do not seem to depend on the physical brain"? But then you asked "where is memory held if not in the brain?" I'm confused here also.

        Finally, in your scheme, am "I" also a virtual construction, or am I made of the same "stuff" as the "original instruction decoder"?

        Edwin Eugene Klingman

        Hi Edwin,

        > Only the root decoder must be physical. All higher-level decoders in the chain can be 'soft'.

        Yes, I agree with you that at some point as you ascend a Type 1 chain, software might take over the work. So I was wrong (or at the very least misleading) to say "if one is physical the other is also". We should not consider software "physical", so that was a poor word choice on my part.

        It will probably muddy the waters to try explain what I had in my head (a vague notion anyway) so I will just accept your hard/soft distinction and move on to what I think is the heart of this: That still does not mean the "root decoder" is physical.

        > And it must be "hard". That is what I mean by "physical". You seem to be saying that my idea of "hard" is an illusion I've obtained from the virtual world, yet you also seem to agree that the "original instruction decoder" must exist. If this is not in some way isomorphic to "hard" (a.k.a. "physical") then I have no idea what you can mean by this.

        Let us consider a situation that is a chain of Type 2 systems and distinguish the various levels of simulation. Level 0 will be the root level, level 1 will be the world simulated above level 0, and so on up.

        For a given Level n to exist, then Level n-1 must exist. While a given level would have access to information regarding higher levels, the reverse is not necessarily true. The higher levels might be much simpler systems than the lower ones, just as Second Life is simpler than physical reality. They may have very limited hints as to what kind of systems are actually running them.

        I am suggesting that what we take to be "physical" (or "hard", i.e. tables and chairs) may actually be at Level 1, not Level 0. The world of Second Life is then at Level 2.

        If our physical world is at Level 1, then, while there must exist a Level 0, I do not want to call it "physical", since that term already denotes things we find at Level 1. In this case, I might call Level 0 "infra-physical", and Level 2 "super-physical", but I am not sure those terms are more helpful than the numbers.

        > Is that what you meant when you said in an earlier comment that "learning and memory do not seem to depend on the physical brain"? But then you asked "where is memory held if not in the brain?" I'm confused here also.

        The link I gave with the statement about learning and memory went to an article about a dramatic experiment done with flatworms, which have the capacity to regrow their heads. The flatworms were trained, their heads were chopped off, and then, after the heads regrew, they were tested again. They had retained the training. The implication I came to was that the learning must have been stored some place other than the worm's physical brain because that had been removed in between the training and retest.

        This I take as evidence that there is a non-brain based, or even non-physical information storage mechanism available for memories and learning.

        > Finally, in your scheme, am "I" also a virtual construction, or am I made of the same "stuff" as the "original instruction decoder"?

        I think that our consciousness is at a lower level than our bodies. If our physical world is at Level 1, that would place it at Level 0. If our physical world is at (say) level 10, then our consciousness could be at (say) Level 5, so I do not know if it is at Level 0.

        Edwin, first I want to thank your for your open reply. Here are a couple replys to your questions.

        You state: "I am subjectively aware of myself and this does not require either measurement or definition."

        I can assure you that your subjective view of your "self" was developed by ALL the measurable information your personal biology obtained throughout your entire life. Remove all of this information and I believe I can say with high confidence that this "subjective self" you believe is present will no longer be capable of being defined. ALL your past, physical information sets the boundaries of your current state of "subjectiveness." This implies that your subjective self is built on your history of collected, measurable, information. So when you say "objective" and "subjective" you simply refer to information on the outer surface (current physical measures), and, information locked inside the boundary of this surface (the entire history of information alluded to above - the information that fills the "volume" in your life). Therefore, your subjective awareness takes root in all your past physical endevours and is not a seperate part .... like saying the leaf does not partake in the life of a tree as part of a whole -or- visa versa..... "sustaining a life" being the context here.

        Also, you have stated: "And although I tend to view it, as a physicist, as the gravitational field, which possesses an inherent, if only primordial, self-awareness, it is just as valid for you to consider it a 'self' field possessing gravitational properties. But only the gravitational properties are measurable. "

        Well, I too am a physicist, however, I also consider our conciousness as supplying a point symmetry to do all its analysis of information - this implies we measure everything as a geometric product - agreement and uncertainty in agreement - dot and curl... including our own "self measurement." Gravity may supply the measurable gauge to the self, however, we can only measure the differences within the gauge and this comes with a dot and curl value, and, this again may go back to requiring more then just the self .... to define the self....

        You also stated" As for a single field explaining everything, my hypothesis is that initially only one "thing" exists, the field. There is no 'outside' or 'inside'. As it evolves, symmetry breaks, and 'local' and 'global' acquire meaning. Any attempt to describe a holistic 'system' has to start somewhere, but this should be arbitrary, since it all must tie together."

        While there may have only been "1" thing at the very beginning of time, we are now immersed in times where there are MANY physically separated "selfs." In the beginning everything may have been "self parallel" and thus only a dot product solution to everything, all self's completely aligned (an incubation, accelerating growth period - like individual spin in a ferromagnet state) .. until a curl (asymmetry) sets in (birth).... increased temperature for the ferromagnetic to demagnetize .... and measured differences (curls) exist between all the "selfs." The "self's" part like the tribes of self's in ancient times. (a GUT on "self's" would need to explain measured past civilation movements also ... and markets... etc)

        On a final note you stated: "You make some assumptions about science finding the correct "context" that indicates you've put a lot of thought into this."

        Well, I like to "think" I put more then thoughts into it ... I like to think I put ALL measures (past and present) we make, and can potentially make, into it. This therefore creats a self that goes from the inner cell, beyond the cell wall out the skin, through the ecosystem and into the solar system (as a NASA scientist you know how we collect information here in the solar system)... and intimately connected out to the far reaches of the universe. If the real, physically measurable descriptions of this instantaneous "self" fosters many testable paths to it's description .... imagine what can transpire when we figure out that it is really a part of the "measurable self" that we physically describe with each valid GUT description (speak of potentially new understandings of the genomes measurable information structure (and when deemed and proven measurable .... becomes manipulative for cures to every physical ailments known and unknown to man)! Now "that" would truely be a Grand theory...... A Measurable Self Physics having the subjective part removed.

        Best regards,

        Tony
