I agree. While that might be possible, it isn't normal. Just as it might be possible for you to push your car down the freeway, you usually don't. Instead, you push a little on the key to get it started, you push a little on the pedals, levers, and steering wheel in such a way as to keep the car on the freeway as the inexorable laws of physics make the car move. Similarly, I think that consciousness can cause some sensitive quantum events to occur in such a way that the inexorable laws of physics amplify those events into cascades of neuronal activity which result in a pattern of muscle activity which results in deliberate action of the body. Now, whether you call this action "natural" I guess is up to you. A lot of human action is certainly unpredictable by the laws of physics, or any other laws for that matter. We also see a lot of people doing what we call "unnatural acts". That is why I questioned whether we know what "acting naturally" really means.Tournesol said:.All the evidence is *that* we do [act naturally in the world]. Consc. does not move things about without the intermediary of nerves and muscles.
Then instead of a car, use the analogy of a Mars rover. In that case the driver is in a different world completely. The rofer is on Mars and the driver is in JPL.Tournesol said:But the driver is in the car.
I agree. But when casting about looking for a candidate that can cause big bangs, that "one" sure seems like a likely one.Tournesol said:And if consc. can add subtle 'tweeks' to the behaviour of such a sensitive and complex organ as the brain -- fair enough., That does not mean it can cause big bangs.
Here's how I see it. I claim that subjective experience is equivalent to knowing. When I say "I know what green looks like", or "I know that is hurting me", that is the same as saying, "I remember having the subjective experience of greenness", or "I am having the subjective experience of pain".Tournesol said:Redutionism, functionalism and identity theory can all answer that question [of the mind influencing the body] perfectly well. What they can't address is the gap between subjective experience and objecive description. It remains to be seen that your theory fares better.
So in my view, if the Primordial Consciousness, (PC) has the ability to know, then PC has subjective experiences. If PC is driving a brain/body, and if PC is the one having the experiences associated with the perceptions and feelings generated by the actions on and of the body, then the gap you identified is closed. The actions of and on the body can be objectively described, and the subjective experience is explained by PC.
The fact that Reductionism, functionalism and identity theory can't address the gap between subjective experience and objective description and my theory does, seems to me to be a positive reason for preferring my theory.Tournesol said:Both theories are compatible with the evidence. You don't seem to have any positive reason for preferring your theory.
Does nothing? In my view, PC cannot break the laws of physics and so can only interfere in the evolution of the universe within the narrow wiggle room provided by uncertain quantum events. Finding just the right clay sediments with just the right organic molecules, by chance, happening to lie on them in just the right places, (or insert your favorite explanation of chemical abiogenesis here instead of the clay thing.) allowing tweaks in the quantum behavior to assemble the molecules in a meaningful way, probably took billions of years. It is also obvious from the fossil record that it took billions of years of trial and error, occasionally punctuated by an asteroid hit, to tweak enough critical quantum events in just the right ways in order to produce the flora and fauna of today. I think it was a huge job and not surprising at all that it took so long.Tournesol said:I find if highly suspicious that, after creating the universe, consc. does nothing for billions of years until sutitable vehicles arose (and why did that take so long?)
(You might have noticed that I think Darwinian Evolution can explain the biological "hardware", like molecules, cells, etc. But I think it cannot explain the "software", i.e. the "meaning" as expressed in the apparent violation of the 2nd Law of Thermodynamics. In short, I think Darwinism can explain the origin of a DNA molecule, but not the encoded pattern of its bases.)
Sorry. It seems obvious to me so I probably didn't express it very well. You originally asked, "f there is a single Consciousness that doesn't need physical vehicles, why would it even seem that there are multiple consciousnesses?"Tournesol said:That is not at all obvious.
Given your premise, I would say that it wouldn't necessarily seem that there are multiple consciousnesses unless the single consciousness actually used physical vehicles (or some other method of fractionating the consciousness so that each fraction is somehow limited). But if the awareness of the single consciousness were limited to the environment of a vehicle, and part of that environment included the perception of other vehicles, then it seems obvious that it could seem that there are multiple consciousnesses: one for each vehicle.
I agree. I didn't say anything "seemed" to the brain. I said it seemed, "from the point of view of any particular vehicle (i.e. human brain)". And as we agree, this "seeming" happens only to the universal Consciousness. This is the same as when you are driving a car, the world seems to be going past your car backwards on either side of the road from your car. It doesn't seem that way to an observer watching your car driving down the road.Tournesol said:Hang on, there is only one thing to which "seeming" can happen, the universal Consciousness. So nothing can seem to anyting else, including a brain.
I think that is an assumption that isn't necessarily true. I think accessibility to knowledge is tricky. Consider a race car driver in the middle of a tense race, where all of his/her attention is focused on the demands of the race. Suppose you had a cell phone, or some other way, of asking him/her a question, and you asked, "Do you know the name of your third grade teacher?" I think the response would be something like, "Don't bother me right now, can't you see I'm busy?", or "I can't think of it right now." or just "...". I think the operation of these human body vehicles generates the same kind of intense noise and demand for attention so that PC just isn't aware of the knowledge from any other bodies. If the noise is shut down, as it is in meditation, then I think more knowledge from beyond the body might be accessible.Tournesol said:But there is only one Consciouness and knowledge from all bodies is accessable to it.
Obviously I have to agree that it does. We see simultaneous activity by a huge number of animals, including all the people and all the nematodes.Tournesol said:Why can't it drive all bodies simultaneoulsy ?
Good question. My answer is, first of all, that it obviously does; each body is not aware of what is going on in the others. Secondly, I suspect it is simply due to some kind of limitation. As you might have noticed, in my view PC is not unlimited (nor is he/she omnipotent, immutable, infinite, perfect, omniscient, or complete).Tournesol said:If it "multiplexes" why does it forget from body to body ?
It might seem that way to you, but to me it is all the consequence of inference and observation. Ad hoc, maybe, but not arbitrary.Tournesol said:That all seems quite arbitrary. ... It seems that you need a lot of additional, arbitrary hypotheses to make your theory work.
Yes, it gets feedback. I think the communication link between PC and brain is two-way. Conscious experience of perceptions and feelings go from brain to PC, and willful intentions go from PC to the brain to cause free-will induced actions.Tournesol said:And doesn't this external consciousness get any feedback from the brain/body ? If not -- what is it supposed to be consciousness OF ?
Ummm...I'm not sure what you're getting at here. My suggestion was that it would be harder to design a conscious robot than a car. Are you suggesting that nature really did design (or at least build) a conscious robot? And that nature built cars only after the conscious robots had walked the Earth for several millions of years?Tournesol said:Harder for whom ? Nature had 15billion years.
I was trying to put the example in common human terms. My point is that we humans have built cars but we have not yet built a conscious robot. I think the latter is a harder problem, at least for us humans.
I think it is a problem for both. I haven't heard an explanation for consciousness emergence by physicalists that didn't essentially deny the existence of conscious experience. And I think the panexperientialists have a lot of explaining to do to make sense of what seems to me to be an overkill explanation.Tournesol said:Historical emergence is not much of a problem for physicalists or panexperientialists to name but two.
Now you're pushing me into a corner. Yes, I think there are some really hard problems here, and my suspicions are that the answers are going to be very complex. Just as the history of science shows that our view of reality and the universe has expanded in scope and complexity enormously from the pre-Socratic times, I think we are in for some more major incremental increases in scope and complexity.Tournesol said:Didn't it create the universe ? While it was still 'primitve', to boot!
Since you are prodding me into this corner, I'll tell you about my guesses about what might really be going on. I think there are extra, large, flat, finite dimensions of both space and time, and that these provide an enormous increase in the "places" available for real things to exist. I think the interactions between our 4D world and the rest of reality are limited to the extent that we can't access much if anything beyond our 4D world with our instruments or senses. I think this is completely consistent with the mathematical notion of manifolds and with the notion of the wall of Plato's cave.
So getting back to your question, I think PC started out extremely primitive. Not much more than a simple ability to know. But from this starting point, and the realization (take that in both senses) of some one fact, the rest of reality was constructed as nothing but patterns in sets of information known by PC.
Roger Penrose presented a diagram in a couple of his books which depicts a rock-paper-scissors sort of relationship between three different worlds: the physical world, the mental world, and the Platonic world. The physical world is our familiar universe. The mental world is the set of ideas, experiences, perceptions, feelings, etc. that is also familiar. People might disagree that it is anything other than a part of the physical world, but it is easy to take the position that it is a different kind of thing from physical matter and energy. The Platonic world is more controversial yet. Whether or not there is such a world containing a perfect triangle, Penrose points out that the Mandelbrot Set is a thing that has been discovered rather than invented. Certainly no human designed its intricate patterns. So if this thing was discovered, where does it reside if not in a Platonic world?
Anyway, he has this diagram showing that a miniscule portion of the physical world (live brains) give rise to the entire mental world. And a miniscule portion of the mental world gives rise to the ideas of mathematics and the concepts that might reside in the Platonic world. And a miniscule portion of the stuff in the Platonic world (the equations of Schroedinger, Einstein, Maxwell, etc.) seem to be able to explain, if not give rise to, the entire physical world.
His diagram shows a paradoxical loop with no clear starting point. In my view, I would break his loop open between the mental and Platonic worlds and extend it into a helix. It would have a starting point at the bottom, viz. PC. PC would then construct some very primitive mental world from which a primitive "physical world" would be constructed next. This "physical world" would have the capacity to store information from the preceding mental world in a more or less permanent way so that PC would have it available but not have to constantly attend to it. (Sort of equivalent to a computer and a hard drive).
To make the next turn of the helix, PC would use that "physical world - computer system" to automatically set up more complex patterns of information and be able to explore the consequences of, for example, running cellular automata on it to see what happens. Seeing the outcomes of these experiments would give PC a whole new level of ideas that would constitute the next level mental world. (Keep in mind that during all of this, PC is the only thinker, knower, experiencer, doer, etc.) With these ideas, some small subset of promising and workable ideas for an even better "physical world" would be instituted in the next level Platonic world, and from there, the second level "physical world" could be constructed. And so on.
I suspect that the helix has made its eleventh turn if each turn adds another spatial dimension to reality. That's only a wild guess, but both Plato and String Theory have suggested the number eleven.
Speculating on the next step, I would guess that, along the lines suggested by Teilhard de Chardin and Frank Tipler, humans (along with possibly other intelligent life forms) will harness the entire energy of the universe and turn it into a single computer system which can then be used to explore methods of constructing an even better set of ideas and plans for a new and better universe, thus starting a new turn on the helix.
So you asked me about PC: " Didn't it create the universe ?" and my answer is "yes". But you have to be clear about what you mean by "the universe". If you mean our 4D space-time continuum for the past 16 billion years or so, then, yes, that was constructed by a complex 11D system which arranged the initial conditions for the big bang and set it going. If, on the other hand, by 'universe' you mean everything that exists, then I would say that, yes, PC created everything in that cosmic helix except for the primordial ability to know that started everything else off.
Now, to polish it off with the really hard question, I would say it's the conscious ability to know ... all the way down.
I agree. But I think I can justify the extra complexity on the basis that it answers all other quesitons.Tournesol said:Since every theory has that problem, including your own, you cannot justify the extra complexity of your theory on the basis that it answers the fundamental question.
You saw through my subterfuge. I tried to cleverly distinguish between consciousness, which I agree is not simple at all, and PC, the Primordial Consciousness. In my view, PC has grown enormously in every respect since the humble beginnings of reality. Today, we should probably use a term like Cosmic Consciousness, (CC), to refer to the conscious driver of the modern physical vehicles of biological animals here on earth. It was misleading on my part not to make this point earlier. But I think you can now understand my reasons for not telling you what I see as the whole story from the outset.Tournesol said:An all-embracing universal consciousness is simple ? Most people don't even think human consciousness is simple.
I'm afraid I will be headed directly to the crackpot corner now, but at least I hope that these ideas have been seen by some pretty smart people as a result of this thread. I thank you all for reading and I would love to hear more comments, especially criticisms and knock-offs.
