Is Matter Conscious? - Can All Matter Be Conscious?

    Matter
In summary, the conversation discusses the idea of consciousness in matter and whether it is possible for all forms of matter to possess consciousness. Some argue that consciousness is an illusion created by complexity, while others propose that it is an emergent process that can be programmed. The interplay of properties and interactions between constituents is said to determine macroscopic properties, such as consciousness. The minimum requirements for a physical system to become conscious are unknown, and it is believed that the brain's vast interconnected network of neurons is necessary for consciousness to emerge.

You know, Jimmy had a lot to say about there being no evidence. Yet when I presented my brain waves evidence, he had nothing to say.

I suppose silence is about as close as one can expect to concession on the web.

Unfortunately most people's idea of emergence is the cartoon version. You get a bunch of stuff together. It interacts. Then some new global property pops out.

So the belief is that separated stuff (ie: substance) has a set of inherent properties (like position, charge, malleability, etc) and then collections of stuff can combine to create a super-stuff, some compound or merely mixed state, which then inherently posesses some super-property.

This is just standard reductionism extended. It is how water molecules are said to come to posess the property of liquidity. H2O has van der waals forces and these organise collections of molecules so that they show some collective emergent property.

This approach to emergence is far too simple to explain a complex system like a conscious brain. It is perhaps an analogy that is 20% useful to get you started, a scaffolding to start lifting you out of reductionism, but quite quickly you have to leave it behind.

Quantum chaos is one study that seems to allow for the question, "what if QM is a result of constraints from the whole?"

You are either not trying or you are simply deluding yourself. Let's move down the importance ladder from the universe and consciousness to Life. Life is an emergent phenomenon and there is nothing in the laws of physics that requires life to form or self-sustain itself. Let's discuss this, then we'll move on to lesser popular nonlinear phenomena like superconductivity, magnetism, spontaneous symmetry-breakings and such.
I thought the common idea among physicalists was that life is just chemistry? If not, what extra property is it that emerged in life?


Okay I see what your point is. So you have 2 options:

1. Claim consciousness isn't real(isn't there)

2. Consciousness belongs to the properties of the constituents of matter(everything is conscious)

Or you have to accept emergence. Well anyway, could we EVER do without a form of magic(emergence, symmetry breaking, hidden variables, etc.) in explaining EVERYTHING we see?
I don't know. Ill leave the explaining of everything up to others. Right now I am just trying to figure out if emergence of C in brains is an abomination of nature.

If you have a rational basis for saying the second law does not have this necessary corollary, then please let's hear it.

If paths that accelerate entropification are available to the second law, then reality must take them. This is a physical fact.



Well okay, but it's not obvious to me how such a path must emerge or be there in the first place. Sounds too anthropic, the path is there because we observe it(or infer about it), otherwise we wouldn't be here observing it. You just move your goalpost further away, from the emergence of life to emergence of "paths", or emergence at the BB.


Resurrected jesus is a strawman argument that is not worth a response.




The origin of a ball falling down to the ground is not gravity. Its falling down is due to the effects of gravity. All you are saying is that life doesn't contradict the law of entropy, which of course i totally agree with.



Thermodynamics is a package of laws in its current formulation. So you have the first three, and now widespread recognition of self-organising dissipative structure as a fourth.


Yes, and we are inquiring into the origin of the dissipative structure.

Self-organization. SO is not an inherent property of matter(well at least as far as we know), though it's reasonable to suspect that it might be. At the moment it isn't possible to predict, based solely on the laws of physics and chemistry, that life would form out of the interactions of atoms or molecules. Though it happens somehow.

Isnt all matter organised in some way, and it did so itself (or however else all matter does it)?

But anyway, i don't see how life could be an example of emergence. Sure life behaves differently than dead matter, but the behaviour is still just matter in motion, and that's been around since the big bang. Since the difference between life and non-life is a difference in the way the matter moves, it is principally equivalent to an atom that moves to the left, versus and atom that moves to the right. It doesn't introduce a new property, just a variation of an already existing one (motion). Compare this with the idea that the atom moving to the left isn't conscious, whereas the atom moving to the right is, and you see there is no logic behind the idea that C is the result of matter doing a particular kind of motion or forming a particular kind of configuration (the brain).

Yes it is. But it isn't possible, based on the laws of physics and chemistry, to predict that life will form. All we can do is observe that it does.

There is one principal difference though - life is not a chaotic system(dead matter is).

No it does. Nothing is the laws of physics and chemistry requires that a system of high entropy must give birth to a sub-system that will resist and fight entropy.

Nowhere so far did i claim that consciousness is necessarily a result of a configuration of matter. If this were the biology forum, i probably would(FAPP it is), but here we are supposed to seek truths, so i withhold judgement.

That we cannot predict something, does not mean it has new properties. For example, if i throw a single ball away, i cannot predict its exact path and motion, but that doesn't mean some new property has arisen. I have heard about "the halting problem", which apparently proves that some behaviour is truly unpredictable. But even so i do not see how this implies that new properties arise, as opposed to just variations of existing ones (as in an atom moving to the left versus an atom moving to the right).

The new property is that YOU have your own human body of zero or very close to zero entropy in a vast universe of constantly increasing entropy. If you cannot(YOU CAN'T!) explain this little fact with your deterministic reductinist logic, then your logic is as good as dead.

Let's get back to self-organization(you insisted to discuss this) and why life forms are local domains of such miniscule entropy. Where in the Standard Model or in chemistry does it say that WE, systems of extremely low entropy, have to be or can be here?

I think it helps to see the issue in terms of three levels of mechanism.

1) atomism: you just have local components and local action.

2) self-organisation: you now recognise that the collective action of local components can develop some self-organised pattern. This is simple self-organisation as we see in chaos modelling and self-organised criticality for instance.

3) intelligent and adapative self-organisation: now something extra is added. By virtue of some kind of systems memory or symbol processing (semiosis), we have rate independent information in control of rate dependent processes (see Howard Pattee).

So life and mind (bios, complex adaptive systems, etc) are distinctive in that they can take SO processes (like a metabolic reaction) and stand back and harness them. The way that DNA can remember when to throw enzymes into a mixture to change its rate. The metabolic process itself is just level 2 SO. But it is controlled by level 3 semiotic organisation.

If you are talking emergence, you will thus have a simple kind of collective property emergence at level 2, but a quite different symbolic, or semiotic, emergence at level 3. And what goes on at level 3 seems now very different because, indeed, it demands a strong disconnection between the rate independent information and the rate dependent process.

So DNA is a very protected and stable molecule that exists "independently", while cellular metabolic processes just run to equilibrium as fast as they can.

Level 3 is quite computational (and not very dynamic). It is just the same as the way the silicon circuits of a computer are engineered to as isolated from real world dynamism as possible. This allows the symbolic code to run as if it had nothing to do with real world rate dependent processes, like battery life, cosmic rays, and other things that would interfere with the pure symbol processing.

I would say that levels 1 and 2 can really be collapsed into the one thing - look closely and all dynamical processes are SO within boundary constraints. QM is an example of that as Pythagorean says.

And level 3 is where the real novelty comes in that "physics" really cannot see at all. But on the other hand, we know all about computers and languages.

Where science is at - when it comes to complex systems, such as organisms with "consciousness" in its many grades and guises - is in trying to put together a combined story on 1/2 and 3.

You can't directly explain 3 with just SO principles (and thus simple emergence). But you still want to be able to build some composite model, some biological ToE, that puts both these aspects of nature, the dynamic and the computational, the rate dependent and the rate independent, into the same story.

Dissipative structure theory is one approach that does seem to bridge the divide. Especially with newer ideas like infodynamics - where the relation between structure and process can be describe more mathematically by combining information theory with hierarchy theory.

Theoretical biology has been talking about this kind of stuff for 30 years now. But reductionism still has such a grip on the popular imagination that even reaching level 2 is a step too far for most.

apeiron,

Just for clarity, I meant that it allows for the question to be posed scientifically/mathematically . The "paradox" has not yet been resolved, but it seems like the answer to the question will contribute to such philosophical discussions as reductionism and emergence. And of course, it's a natural assumption to many of us that it will indeed point the way you indicated, but I want to be able to prove it formally before I can claim it.

I'm also curious if you know how these "levels" are quantified. Not as a challenge, but I am trying to find the analogy/terminology in dynamical systems language.

Level 1 would be simple action - apparently without restraint. The naked expression of a degree of freedom without any "feedback" or other global level interaction. So this would be the realm of linear outcomes (Newtonian mechanics) or exponential outcomes (as in unconstrained growth). That is a linear/log relationship.

Level 2 would be characterised most usually by powerlaw behaviour. A system involves two kinds of free action in interaction - ie: bottom=up construction and top=down constraint. In a dynamical system, both construction and constraint will be exponential or log, And thus the equilibrium outcome of what emerges is log/log or powerlaw. This is why SO is associated with powerlaws or self-similarity - scale indifference.

Now is level 3 also associated with a characteristic quantitative scale? Taking the DNA and enzyme example, level 3 is about controlling the rate of SO processes, so the process would have an equilibrium point and the enzyme would shift it. So it would seem that level 3 controls the slope of the powerlaw, the lyapunov exponent.

But level 3 also seems characterised by gaussian outcomes. Genes responsible for a trait like height or intelligence for instance. Strong constraint creates a single scale of variation (whereas powerlaws are about variation across every scale).

So level 1 = naked atomistic construction and thus unconstrained forms of action.

Level 2 = construction interacting with the constraints that the system is generating, a feedback situation and so the statistics become powerlaw.

Level 3 = SO process with either a rate or variety that is controlled by external information. The action thus again becomes reduced to a single scale - a form of linearity. But now a single scale that can be finely controlled. So action becomes directed (towards a systems purposes).

Ok, I think I understand somewhat. Level 3 is most tangible to me, the "motion" of the lyapunov "constant" (an interesting terminology for something that isn't so constant).

level 2 seems to imply a constant (positive?) lyapunov exponent? Solutions may grow away from each other, but the lyapunov is constant with respect to time?

level 1 seems to be 0 lyapunov exponent, or possibly negative? as solutions all tend to go toward some constant equilibrium (negative) or all tend to stay parallel (zero)?

To nitpick, none of the levels seem outside of Newtonian mechanics to me. The simple pendulum is already a nonlinear problem (unless you approximate it for small angles). Fluid dynamics and turbulence are a high dimensional nonlinear system.

I suspect even entropy is a matter of degrees, so there will be a spectrum that ranges from little to much entropy. I would compare this with a car going slowly, then going faster and faster, etc. If so, it is about quantitative differences, and not about the emergence of qualitatively new phenomena.

However, I am no expert on this so correct me if I am wrong. In particular, i would like to know what entropy actually physically consists of, and how it entails new (emergent) physical properties.

The issue remains that it is proposed that consciousness (whatever it is) is completely absent at some moment in time, so there is not even the slightest degree of it anywhere, and then consciousness comes into existence. So we need to find a physical phenomenon that does not come in degrees of complexity and has no spectrum ranging from [little] to [much]. To me, it seems like any example of mass in motion (including life)is not acceptable since that has, in some degree, been around since the big bang.

Let's get back to self-organization(you insisted to discuss this) and why life forms are local domains of such miniscule entropy. Where in the Standard Model or in chemistry does it say that WE, systems of extremely low entropy, have to be or can be here?
I don't think it is known exactly how or why life arose, but is there anything pointing towards the idea that it isn't a (unexpected) consequence of the different chemical forces at work, and consists of something more than those forces?

All the levels would have to include Newtonian mechanics as their most reduced view. But clearly, the whole point about nonlinearity is that it is the emergent higher dimensionality that the Newtonian view "cannot see". So mechanics can handle a simple pendulum, but as soon as there is a three body problem, it is lost as now there is a need to quantify the richer interactions.

This would have been true if a human body wasn't comprised of approximately 100 trillion cells. That's way out of the ordinary for such a small region of space to contain such low level of entropy in a universe of ever-increasing entropy.


However, I am no expert on this so correct me if I am wrong. In particular, i would like to know what entropy actually physically consists of, and how it entails new (emergent) physical properties.


The broken egg example is a good one and illustrates the direction of entropy. On this background, the processes of life are more evidently emergent(non-linear).

Only if superdeterminism is true. But superdeterminism raises more questions than it answers, right?

What I mean is that the three body problem completely follows Newton's mechanics, it's just not analytically solvable using only the techniques from the time. But the fundamental principles still hold! There is nothing in Newtonian laws that requires philosophical reductionism.

What do you mean by that exactly? Newtonian mechanics was based on a reduction to local or efficient causes and so the exclusion of global constraints (global constraints were taken as read, static and immutable, so therefore something that just dropped out of a very reduced description of reality).

I don't see how that kind of thinking is forced by Newtonian mechanics. I really can't even see how philosophical reductionism is defensible as an absolute, honestly. Maybe in Newton's time it was, but it was a result of interpretations and philosophy, not the formalism of netwonian mechanics.

The superposition principle is known to be incorrect when you are considering nonlinear systems. Because of the difficulty in solving nonlinear problems, and the fact that the low-hanging fruit still hadn't been picked at the time, I can see how philosophical reductionism might have been common.

That's how things are taught in first/second year physics using all the parts that are reduced, but by third/fourth year it becomes more integrated: Lagrangian mechanics, for instance, are a reformulation of Newtonian mechanics, they don't change anything fundamental about it. What's changing is the way we apply it. And that we can actually manage nonlinear problems now that we have computers, but this is through many high-order approximations to classical systems that cannot be analytically solved.

I thought you meant philosophical reductionism because you often speak of the "reduction to the sum of its parts" which is philosophical reductionism.

But also, because scientific reductionism is a tool, not a philosophy. I didn't think there was any reason to argue philosophically against something that's not a belief, unless it's perverted into something like "greedy reductionism".

Scientists, by virtue of being human, are already comprehensive/holistic thinkers. Reductionism in science is meant to complement, not replace, the comprehensive/holistic views of individual scientists (or cliques of scientists, as it may be). Reductionism, for instance, can be used to ask about the mechanisms contributing to emergence.

Ok, so then you agree that reducitonism is not inherent to Newtonian mechanics? Neither is linear phenomena? And that Newtonian mechanics can be used to completely describe nonlinear and emergent systems?

What do you actually understand by reductionism?

There are two kinds of meaning at least.

1) That all causality can be reduced to efficient causes - localised or atomistic pushes and pulls. This is what holism challenges by pointing out that systems also involves top-down causality. Or indeed, Aristotle's full set of four causes.

2) Reductionism also can mean just generalisation that leads to model building (a reduction in the information needed to model the world). In this epistemological sense, both atomistic reductionism, and holism, would be reductionist.

Newtonian mechanics is of course reductionist in both these senses. So reductionism is "inherent" in mechanics. His laws really do treat the world as if it is reducible to efficient cause.

Now does this mean that the same laws cannot be used to generate - from the bottom-up, in constructive fashion - non-linear results? Of course not. Does it mean that the resulting models lack the holistic features I am talking about? Yes, it does. Although boundary conditions and other necessary contraints are of course plugged in by hand normally. They are implied rather than present in the model.

The third law - action and reaction - are a perfect example of this. A global context that is necessary to resist the local action is reduced to the cartoon notion of a "reaction" - an exactly counterbalancing force vector.

Self-organisation takes place when the conditions are right. But SO models don't model that extra bit of "how the conditions become right". The global context is left informally specified. It is not part of the model.

The meta-physics of non-linear systems, or chaos and dynamism, is very poorly understood by most people. But then it is still a relatively new area of modelling.

Thank you, that clears some things up. This is what I was going to point out: boundary conditions and the third law.

In my view, complex systems are one class of systems and nothing fundamental has changed, really (no additional fundamental laws are required, it's just a matter of a different case within the framework of the same fundamental laws. As you say, different metaphysics.).

It seems to me that Newton felt that way, from his preface in Principia, and the Copernican Scholium he added later to Principia (but only got added 200 years later in the actual print).

Once again, this does not reflect my position. I side with those who believe more is different.

For instance, Newtonian mechanics is symmetric in respect of time. Events can run in either direction as a fundamental aspect of the description. This same time symmetry then propagates all the way through even complex descriptions of nature, such as Boltzmann's statistical mechanics. And so the arrow of time remains a fundamental mystery. There is no point along the elaboration of a time symmetric model that suddenly produces the "emergent property" of uni-directional time.

It would thus be a very different approach to model time as a top-down global constraint on local events. A completely different way of thinking about "mechanics".

To connect back to the OP, the problem with consciousness theorising is that everyone is stuck at level 1 modelling - seeking bottom-up emergent stories on how matter can produce mind.

The way out of this overly reductionist mindset involves a double shift in perspective. (Yes, it is a big paradigm shift).

You have to see that even self-organising matter involves a systems logic if we were to describe reality fully. So level 1/2 thinking.

And then there is yet a further trick going on which I called level 3. The harnessing of SO processes by semiotic or symbolic mechanism.

Level 1 thinking is exemplified by Newtonian mechanics (and even statistical mechanics and deterministic chaos).

Level 1/2 would be hierarchy theory and systems thinking.

Level 1/2 + 3 is the complete package that gets you to models of real complexity - complex adaptive systems, or life and mind.

Ok, I agree that understanding consciousness will require a paradigm shift.

But don't you think we've already made the the first paradigm shift from level 1 to 2? And to me, it seems to have fallen directly from Newtonian mechanics, from which statistical mechanics is derived and where entropy came from. The arrow of time is not an insignificant topic of cosmology nowadays.

Level 3 of course, is a framework now and still needs to be formalized and well, reduced, but I think it's the direction we're already headed. For instance, there's a conference coming up in May that touches on holistic aspects, and of course, quantum chaos is another example where mechanics might be a function of the system dynamics.

(May '11 consciousness conference in Stockholm)
http://www.consciousness.arizona.edu/

Some of the topics there, particularly the notion that consciousness is an aspect of the universe (not just humans) are particularly appealing.

I've just been reading Turing's paper on morphogenesis which seems relevant to mention here too, as his perspective seems to contribute to Level 3 thinking.

Some of the topics there, particularly the notion that consciousness is an aspect of the universe (not just humans) are particularly appealing.

Are you serious? I can't see a single proper neuroscientist among the speakers. Just the crank fringe - quantum mystics, psi researchers. Oh, there's one session on neuronal coherence hidden in there. But really...

Not only will ad hominem be insufficient to make a point, but it's application is not even relevant.

The point is not whether they're correct or not. The point is that people are moving in the direction of holism as an approach. But of course, your response demonstrates the reputation of holistic approaches . You must recognize SOC and chaos have both had similar reputations depending on who the author is and what exactly their claim is.

Holism-type theories are difficult to verify and (because of our small brains) really must be reduced to be verified (empirical observation). This has a tendency to destroy emergent properties. To preserve them (in the dynamical sciences) we have to look at the projections of state trajectories so that we can get an idea of how one member behaves in the group but we know the behavior can't be reduced to one member of the group, as the behavior is complex and irregular when it's coupled to the group dynamics (as Newton ultimately confessed about the n-body problem).

But once we start looking at projections of a state trajectory, we've lost information about the dimension over which was projected (like the shadow of a cardboard cut-out can be made to look exactly like the shadow of a human is a simple 3D->2D example). This leads to a lot of claims becoming unfalsifiable, since complex systems are more like 600D-->4D. And of course, because the verification is often performed computationally for such complex systems, lots of computation artifacts have been published.

So hopefully this demonstrates why there's a heavy burden of proof on SOC. I hope you can appreciate why I'm playing Devil's advocate here. I obviously don't think quantum mysticism is worth discussion.

You have made comments along the lines of life being a necessary event in the universe following the laws of entropy; one of the talks for the conference seemed to mirror that sentiment for consciousness in more general terms and of course this is why I mentioned the Turing instability: the universe tends towards many scales of local pattern generation which globally, is entropy generation.

You needn't focus on Penrose or any particular member of the conference, just the general trend of holism in the sciences.

Pfft. It is their theories I criticise, so how is that ad hominem?

.

Why is their lack of correctness not a problem? And which one among this bunch are holists in your opinion? Alwyn Scott was genuinely, but he is now only present in spirit :wink:.

Do you ever read anything closely? You're telling me about how to be a holist now? Why do you keep inventing positions I could not possibly hold?

Where is the genuine holism in these speakers? Again you appear to be talking through your hat. Just name the actual speakers you claim to be "holists".

It's ad hominem because you just called it by a derogatory term (that you know has a certain connotation attached to it). You didn't confront any of their arguments at all. You might as well have not said it.

you did, however, say:

"The way out of this overly reductionist mindset involves a double shift in perspective. (Yes, it is a big paradigm shift)."

But here we have three holistic approaches being presented at a single conference:

1.
Is consciousness an epiphenomenal happenstance of this one particular universe among multitudes, as proposed in M-theory by Hawking and Mlodinow? Or are consciousness and intelligence intrinsic to the fabric of reality?

2.
Does the conscious observer collapse the wave function? Is consciousness an emergent property of complex computation, or irreducible and intrinsically related to spacetime geometry? How did the universe arise from nothingness? What is entanglement?

3.
Evidence suggests brain-generated electromagnetic fields provide feedback on brain neuronal activities, bolstering long-standing electromagnetic field theories of consciousness.

and yes, JohnJoe McFadden (3) is a holist:

My point is that the problem isn't about reductionism vs. holism.

So what is the problem then? Can you actually spell it out?

As to your cited examples of holism, really they aren't in any serious evidence-based sense.

You can safely say (in my long experience) that anyone who mentions quantum and consciousness in the same sentence is going to be a crank. No matter that there is an academic industry in this nonsense.

Holism stresses top-down causality and nested hierarchical design. And we can tell how far down that causality reaches experimentally.

Neuroscience finds that global mental state correlates right down as far as individual neural responses. And even down to synaptic level - but starting to become fuzzy.

There is no good reason to suppose it reaches down below that to individual microtubules or other sub-cellular structure that might get you in reach of localised quantum coherence.

To take the alternative approach - arguing for coherence as a global state - is crank too because there is no evidence for global mind fields, nor any credible mechanism for how they would act downwards to constrain local neural activity. (And why would it even need to when there is abundant neuroscientific evidence for biological machinery doing that job already).

I don't see that you understand the issues you wish to defend here.

Of course not, but my point is that holism is abundant already. Holism, in general, isn't the answer, and we're not stuck in reductionism. And the merger of holism with reductionism is no new story. It's always been a matter of verifying holistic claims with reductionism because we think holistically already.

Being able to verify the generalizations of holistic claims with reductionism is exactly what has worked for a long time. i.e Alchemy got reduced by physics and became chemistry.

And of course, as I mentioned earlier, quantum chaos is an example of this that has potential to give us insights into principles of emergence:
http://www.nature.com/nature/journal/v412/n6848/full/412712a0.html

This is the general trend of paradigm shifts. The choke point has generally been finding specific techniques to verify the holistic claims.

Similarly, consciousness will be a merger of valid holistic theories from (for instance) psychology and reduced models of brain components (neural networks). And of course, the neural networks can be reduced to smaller components in the brains (neurons, glia, processes like volume transmission and field effects).

You can safely say (in my long experience) that anyone who mentions quantum and consciousness in the same sentence is going to be a crank. No matter that there is an academic industry in this nonsense.

Well, that's nice, but there's actually good formal arguments to use in place of your experience, and you finally did even after I told you it was irrelevant, since I'm not defending these theories. Here's a journal you can post for efficiency next time: ;)

Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Apr;61 4 Pt B 4194-206.

But I think you missed my point and mis-characterized my stance. I'm not defending any theories. I'm demonstrating that (as I've said) there's no lack of holistic theories in science.

Holism is elusive. It's difficult to verify holistic claims. A lot of work in theoretical science comes from finding ways to reduce holistic claims to empirically verifiable statements.

The more productive direction I was hoping we'd go is to actually approach these, since the case doesn't need to be made for holism. It is already accepted, and was already implicitly expressed.
