Understanding Dualism: Exploring the Mind-Body Duality

[seeker03]

Dualism.

I was wondering if anyone could help me with this. If our mind and our body can interact, and our mind is mental and our bodies are physical, then there should be some sort of integration. Yet this integration cannot touch at a mental level and a physical level, because this is what dualism states. Then, how does our body and mind interact according to dualism?

 

[selfAdjoint]

Lots of answers to this one. Here's one to try, epiphenomenalism. It means the mind is just a byproduct that the body, especially the brain makes, like the noise a machine makes when it's working. The classic objection to this is that the sound doen't affect the machine but the mind can affect the body. But that's pretty silly; the meachine noise was only a simplified model, you shouldn't push it too far.

Combine epiphenomenalism with evolution, you get an epiphenomenon that happened to evolve, turned out to have survival advantages, and flourished. So that's what it could be. Just an accidental byproduct of cellular working that's been enhanced by evolution.

 

[seeker03]

thanks! that's a pretty good analogy. but how can the mind exist without the body? in your analogy, the body is an extension of the mind. but from our senses, it would seem that the mind is an extension of the body.

 

[Mentat]

seeker, your problem started when you differentiated "mental" from "physical". If mental events are not physical, then they cannot interact with the physical body (which they obviously do); therefore they must be physical. For an explanation of why non-physical things cannot interact with physical ones, see the ninth post down on the third page of this thread.

 

[hypnagogue]

Or, for an ongoing explanation of how phsyical/non-physical interactions could in fact be a conceivable, coherent framework, check out this thread.

 

[seeker03]

thanks guys, both of those threads contain very relevant information. :)

One explanation is an intelligence at the cellular level. Each cell carries it’s own intelligence. Just watch a cut heal without you having to instruct it.
We think our mind is in our brain because that’s where the most cells are.

This cannot be correct.

First off, if cells were conscious of pain, then there would be no need of a nervous system that relayed such information (of being cut) to the spinal cord and brain.

Secondly, if a cell was conscious, then why would anything have every developed a brain, when any collection of cells would suffice?

Lastly, if pain was felt by a cell, then why does the cell (along its neighboring cells) not respond before any electrical stimulus reaches the spinal cord?

 

[full-time-climb]

Cells do act without control coming from the brain. Let's just think back to before we had a brain. When we were just a single cell. Every cell new exactly what to do and when to do it. Even after we had developed a brain we still have systems of cells that do not require instruction from our brain.

Interesting don't you think.


John

 

[Iacchus32]

Yes, that is pretty amazing!

The intelligence factor is definitely encoded within the cell. At which point it becomes a matter of where the cell "takes up residence" and specializes in.

And it's a good indication that consciousness even occurs at the cellular level.

Actually, a cell never knew "what to do" or "when to do it", until a CNS evolved. Think about it, a plant doesn't know what to do or when to do it, and it's a whole collection of cells. No, a cell may have interacted with its surroundings, but it never knew it was doing this.

 

[Iacchus32]

And yet who's to say that human society isn't altogether different than a collection of cells? And here, while we may be speaking of something occurring on a higher level, we're basically speaking of something which is fundamenatlly the same.

 

[full-time-climb]

Great points Mentat. Do you know if the nerve cells of the brain are radically different than the nerve cells in the body?

Some arguments on dualism.

Dualism can be explained by assuming that God keeps the physical and the experiential perpetually in sync, as I believe Liebnitz proposed. I don't buy this. However dualism is definitely a problematic position.

Epiphenominalism (supervenience) is sometime used to get around the problem, but it doesn't work. Ryle and others suggest that consciousness is no more than the steam from a train whistle, on the basis that the steam has no effect on the train. The problem with this view is that it's complete nonsense. Of course the steam has an effect on the train. There is no known scientific case of an epiphenomenon having no effect on the structure from which it arises, so claiming that consciousness is an exception is a pretty thin argument.

Also it has been well argued on logical grounds (Dupree) that 'supervenience' (an epiphenomenon 'supervenes' on what it is epiphenomenal on) must be symmetrical (will find ref. if required). If causation works one way it must work the other way as well. Epiphenominalism is therefore not a very plausible idea.

I think that few current thinkers go for 'substance dualism'. Most prefer 'property dualism', one substance but two aspects.

Substance dualism only makes sense if mind and matter reduce to one substance, as Buddhism asserts. Property dualism has nothing to say about the ontology of mind and matter.

Some property dualists assert that mind and matter are both material. This is counterintuitive at best and outright insanity at worst. Still, if someone chooses to believe that exerientia are physical objects it's hard to argue with them. It's like arguing with people who believe they're Napoleon, logic doesn't seem to apply.

As for the idea that consciousness has evolved it contradicts science. As currently defined science must assume that consciousness has no function. In this case consciousness bestows no advantage on an organism and cannot be selected for.

That's rather a "straw-man" argument, don't you think? I mean, yes, if all of us humans produce some higher consciousness through our own minute processes, then your conclusion makes sense, but it is an added assumption that we produce such a gestalt, right?

No, I don't think there's much difference in structure between interneurons (in the neocortex of the brain) and motor or sensory neurons (which are also in the rest of the body).

Just to be clear, this "God" idea couldn't work either since the "god" of this concept would have to be neither physical nor non-physical.

Well, when you think about it, this is no dualism at all. In fact, Materialists would assume that mind and matter are of one substance too: matter!

Still, if someone chooses to believe that exerientia are physical objects it's hard to argue with them. It's like arguing with people who believe they're Napoleon, logic doesn't seem to apply.

Well, of course I'm not saying that those supposed phenomenological entities are physical, I'm saying that they don't exist at all, and that the process of "mind" and "thought" can be explained completely in terms of matter.

As for the idea that consciousness has evolved it contradicts science. As currently defined science must assume that consciousness has no function. In this case consciousness bestows no advantage on an organism and cannot be selected for.

This part is just wrong, as there are many books (including Consciousness Explained) which explain why consciousness would evolve.

First off, the australopithecines (sp?) and subsequent primitive Homo species could have used superior intellects to outwit larger predators and to remain socially inact.

There is also the matter of coordinating attack, but this too is part of being a social animal, and being social does indeed have evolutionary advantages to it.

Materialists are generally property dualists, since most people find that it is logically difficult to say that 'love' is material. But I agree that they are not dualists as to substance.

Well, of course I'm not saying that those supposed phenomenological entities are physical, I'm saying that they don't exist at all, and that the process of "mind" and "thought" can be explained completely in terms of matter.

So a feeling of 'anger' is a physical object and any associated phenomenolgy doesn't exist? Hmm.

The most innapropriate and arrogant book title ever. Dennett had a good try but hardly anyone agrees with him. His view doesn't stand up to analysis.

I don't remember him talking about consciousness evolving. However if consciousness is non-causal then it didn't evolve, end of story. You can argue that the brain-states underlying some states of consciousness evolved, but unless consciousness is causal and freewill exists then consciousness has never had anything to do with evolution. It's impossible in principle that it did.

Your view escapes this problem by the only possible route, by saying that consciousness is physical. But if it is physical how do explain the 'explanatory gap', and why are neuroscientists looking for its correlates, rather than the thing itself?

(Btw - I'm not trying to be confrontational, just up front. )

First off, the australopithecines (sp?) and subsequent primitive Homo species could have used superior intellects to outwit larger predators and to remain socially inact.

Yes, but this is physical computation. Whether these entities were conscious of that computation or not could have made no difference to their behaviour in your view.

I can see that there is some logic to the idea that consciousness is physically caused. But to say it is physical seems very illogical, since how can matter self-reference? Maybe I haven't understood the argument for it, but I have tried.

Indeed. Anger is a release of certain hormones, coupled with the firing of a few interneurons...nothing non-physical required.

It's not a physical object, but it is a physical process.

The most innapropriate and arrogant book title ever. Dennett had a good try but hardly anyone agrees with him. His view doesn't stand up to analysis.

Interestingly enough, though, while you're right that very few people say they agree with him, every Materialist theory of consciousness (usually written by neurologists or cognitive scientists) can be shown to be another way of saying exactly what Dennett said (even if unintentionally).

A couple of examples are the selectionist theories of William Calvin and Gerald Edelman.

And I appreciate this. However, some neuroscientists do indeed believe that "gap" can be crossed (this usually being stated in terms of a discovery that the "gap" didn't really exist in the first place).

The examples I mentioned above, along with Joseph LeDoux (in his book, Synaptic Self) are just a few.

Yes, but this is physical computation. Whether these entities were conscious of that computation or not could have made no difference to their behaviour in your view.

Indeed, but now you are referring to self-consciousness. Minor consciousness can evolve into self-consciousness, but not because it is beneficial to the species, simply because it is not deterimental...and it has helped us ascend to the "top of the food chain" in more recent times (the past 6,000 or so years).

I can see that there is some logic to the idea that consciousness is physically caused. But to say it is physical seems very illogical, since how can matter self-reference?

Hebbian cell-assemblies firing in synchronous self-stimulation, thus relating one "thought" to another by the adding of new synchronicities in a "darwinian machine" we call the neocortex? That's William Calvin's take. Consciousness would not be matter, but a process that matter does.

 

[Canute]

Hmm. I have a feeling we aren't ever going to agree about this. Still...

So why do neoruscientists, when they search for the neural correlates of anger, bother to ask their subjects whether they feel angry or not? It can't be because feeling angry is not the same thing as a bunch of neurons. It reminds me of the old behaviourist joke of two cognitive scientists of the Watson/Skinner school meeting. "You're very well today, how am I?"

Interestingly enough, though, while you're right that very few people say they agree with him, every Materialist theory of consciousness (usually written by neurologists or cognitive scientists) can be shown to be another way of saying exactly what Dennett said (even if unintentionally).

'Every' is much too strong, and few of these theories are as well thought out as Dennett's. But you're partly right. In fact Velmans (I think it was) practically accused him of stealing 'hetero-phenomenology' from a paper of his (can't remember what Velmans called it). The fact is, however, that very few people think that Dennett explained consciousness. My personal view is that Dennett is very clever and writes well, but he is patronising, dishonest in his thinking, and has a view derived from temperament rather than logic. That goes for 'Darwin's Dangerous Idea' as well. Thank God he isn't here to sue me.

And I appreciate this. However, some neuroscientists do indeed believe that "gap" can be crossed (this usually being stated in terms of a discovery that the "gap" didn't really exist in the first place).

True, many of them believe that (wouldn't you if you were a neuroscientist?). But the issue is open.

Excuse the long quote but it seems relevant. From a recent conference report:

“It would seem reasonable to expect any conprehensive account of consciousness to accommodate two of its most fundamental attributes: that we have a self-centred sense of experience and that this sense is somehow linked to the conditioning of our physiology. Yet those conversant with post-Cartesian philosophy will know that time and again significant doubts have been raised about any apparently obvious link between mind and body. So of all of the questions implicated the scientific study of consciousness perhaps the most pressing is to what extent, if at all, does our mental life correlate with bio chemical activity at the neuronal level? Until this is resolved we will be unable to reconcile the data gathered from phenomenological analysis of introspective experience with tha derived from neuroscientific analysis of brain behaviour. The infamous gap will persist.”
Robert Peperell ‘Between phenomenology and neuroscience’ A report of the ‘Towards a Science of Consciousness’ Conference, Prague, July 2003) From JCS Vol 10 No 11, 2004 p 85

It includes notes on a presentation given by neurophysiologist
Karl Pribram,

‘One can no more hope to find consciousness by digging into the brain than one can find gravity by digging into the earth’s centre’. His solution to the mind/brain problem is, much like Thompson, to reject the assumption of an inherent division and instead to regard the brain as but part of a larger web of causations impinging upon each instantiation of consciousness, including social systems and culture. We concluded by invoking a spiritual dimension to the quest for human understanding; not the kind of spiritualism one suspects Honderich had in mind, but rather a kind of ‘pervading consciousness’ which partakes of patterns that seem to be an intrinsic part of nature and human experience, including ‘quantum mechanics, organic chemistry, history, interpersonal interactions, or religious beliefs’ – all touched on to some extent in this wide-ranging presentation.”

Robert Peperell ibid.

Indeed, but now you are referring to self-consciousness. Minor consciousness can evolve into self-consciousness, but not because it is beneficial to the species, simply because it is not deterimental...and it has helped us ascend to the "top of the food chain" in more recent times (the past 6,000 or so years).

Is 'minor' consciousness the same as the now debunked 'proto-consciousness?

This having it both ways. If consciousness is no more than non-detrimental then how did it help us ascend the food chain?

Hebbian cell-assemblies firing in synchronous self-stimulation, thus relating one "thought" to another by the adding of new synchronicities in a "darwinian machine" we call the neocortex? That's William Calvin's take. Consciousness would not be matter, but a process that matter does. [/B]

Sounds impressive but boils down to 'consciousness is brain' and doesn't address the difficult questions.

I wonder if our disagreement is down to you discussing 'phenomenal consciousness' and me discussing 'what it is like to be'? What do you think?

In truth, 'phenomenal consciousness' and 'what is it like to be' are the same thing. The materialist position on consciousness bolsters itself either by deluding itself into believing that phenomenal consciousness "doesn't exist," or by assuming that correlation between brain processes and subjective experiences implies causation. I agree with you, Canute; despite some claims to the contrary, consciousness by and large remains very much unexplained.

I hate to disgree when you've just agreed with me but...

Phenomenal consciousness implies consciousness of phenomena, but consciousness at its simplest, as 'what it is like' does not imply this, or at least not necessarily. I'd say that this distinction, or the failure to make it clear, is a major source of misunderstanding between people arguing that consciousness is fundamental (like me) and those arguing that it consists entirely of sensory data and thus must be emergent from brains.

I'd also argue that the correlation between brain processes and subjective experiences does imply causation. It's the nature of that causation that is the issue.

The one view that really is wrong is, as you say, thinking that we've made any progress on solving these problems scientifically yet. Perhaps we will in future, and perhaps we won't. Perhaps the answer lies in science, and perhaps it doesn't. So far we don't have the scientific evidence required to make up our minds.

From the scientific perspective it's a matter of opinion whether physicalism is true or not, since it's a metaphysical theory. If I ran the education system (God help us) this is the first fact that all children would learn at school, followed by a list of all the other things we don't know but make assumptions about.

Oops. Slipped into rant mode.

Building a bridge between physical and conceptual existence. How is this done?

By eliminating the physical - No bridge is necessary.

Thats right - There is no physical world to speak of. Your reality is entirely conceptual.

Your mind, your body, the world we live in is not physical. I repeat - There is no physical reality.

I thought I'd toss out something not discussed. That a concept acts in accordance with our understanding of the physical. A concept quacks like a duck. Therefor it is. Conceptual reality mimics that of the physical, and we think in the physical sense.

Does that make us physical?

Well - Yes - But not really.

No bridge is necessary.

LOL! Yeah, I know that we still rely on the utterly heterophenomenological, third-party approach in our study of psychology, but that could just be because we don't yet have a full enough understanding of the physics behind whatever emotion we're discussing.

True, many of them believe that (wouldn't you if you were a neuroscientist?). But the issue is open.

Indeed it is. However, in much of Consciousness Explained, Dennett wasn't so much proving his own theory as disproving the theories of others (which required Dualism). So, if Dennett can show that Dualism is ridiculous (and that too is still open for debate, but I think he nailed it pretty hard), then neuroscientists have basis for their hope of explaining consciousness.

Is 'minor' consciousness the same as the now debunked 'proto-consciousness?

Well, I wouldn't call it "proto-consciousness" so much as a development of the primitive linguistic abilities (through which memes are propogated in social structures) and comprehensive abilities of hominoids.

This having it both ways. If consciousness is no more than non-detrimental then how did it help us ascend the food chain?

Well, it's helped us in progressing technologically, right?

I'm not sure. "What is it like to be" is subjective experience, but I have no problem with belief in subjective experience (as I myself have had subjective experiences, and so I know they exist), obviously, I just have a problem with the belief that these experiences have a phenomenal existence (seperate from the workings of the neocortex).

Just to play some devil's advocate (assuming 'conceptual' as used here refers to the ontological nature of 'consciousness'): the conceptual is that which you experience firsthand, and it is the medium through which you observe 'the world' and infer the existence of the physical. So
1) our notions of the physical are entirely contingent on our experience of the conceptual;
2) the conceptual has an axiomatic claim to existence, whereas the physical has only an assumed/inferred one.

I conclude that if any of these two notions is to be discarded, it should be the physical.

I'd also argue that the correlation between brain processes and subjective experiences does imply causation. It's the nature of that causation that is the issue.

Certainly a reasonable assumption, and one that we probably need to make in scientific investigation of consciousness, but still an assumption nonetheless. Correlation in and of itself does not imply causation.

 

[UltraPi1]

That's exactly what I'm saying, along with everything else in the universe - No exceptions.

Why not really?

Not really because the universe is not physical as stated.
I initially said yes it is physical because everything points to that conclusion. We all believe it to be so. Why question it when it acts flawlessly. Few if any would ever consider our existence as non-physical.



To play the other side of the coin.

Think of every entity in the universe as a concept (thought). Each concept acts in accordance with what we term physical laws. In short - the universe is physical, but not really. I contend that if you could examine the fundamental - You would find ... Not a damn thing. A thought has no size, but for the size of the thought. The fundamental is not a thing except for the thought of a thing. Physicality is a conceptual illusion.

I know what you mean about relying on third-person evidence. But if you think about it consiousness is completely invisible to third-persons, and in fact we rely entirely on first person evidence. What we see from a third-person perspective is behaviour, not consciousness. Alos, however much science we do we will never prove that emotions exist in a scientific sense. How is physics going to explain something it can't prove exists?

Wow. I've never seen a Dennett-hater before. I guess we're all entitled to our opinions, but I've never noticed any of these attributes in Dennett.

Ah, but you agree with him.

Indeed it is. However, in much of Consciousness Explained, Dennett wasn't so much proving his own theory as disproving the theories of others (which required Dualism).

He did a pretty good job as well, but dualism lives to fight again. His book had little impact on the debate as far as I can tell from what emerges in the literature.

So, if Dennett can show that Dualism is ridiculous (and that too is still open for debate, but I think he nailed it pretty hard), then neuroscientists have basis for their hope of explaining consciousness.

Ho showed some forms of dualism to be illogical, but failed (imo) to deal with the more logical forms of it. (I also think that (ultimately) dualism is false, but only at the limit).

Well, I wouldn't call it "proto-consciousness" so much as a development of the primitive linguistic abilities (through which memes are propogated in social structures) and comprehensive abilities of hominoids.

Are you saying that consciousness depends on language? You wouldn't be alone in that (Wittgenstein agreed I think) but it's speculation with little evidence to support it, and plenty against.

Well, it's helped us in progressing technologically, right?

Do you think that consciousness (our ability to know we are experiencing) is causal? It's not the scientific view. According to science consciousness had (and has) no effect on our technological progress.

I'm not sure. "What is it like to be" is subjective experience, but I have no problem with belief in subjective experience (as I myself have had subjective experiences, and so I know they exist), obviously, I just have a problem with the belief that these experiences have a phenomenal existence (seperate from the workings of the neocortex). [/B]

If you KNOW that subjective experience exists, but science cannot observe subjective experience, then how can subjective experience be the the same thing as a brain state. How do you know subjective experiences exist?

That's not what I meant. I was saying that phenomenal consciousness is 'intentional', it is consciousness of something. 'What it is like to be' is a more fundamental definition, and a more fundamental state.

It's very hard to argue that phenomenal consciousness is not physically caused (the momentary nature of it anyway), but that isn;t the case for 'what it is like'.

Certainly a reasonable assumption, and one that we probably need to make in scientific investigation of consciousness, but still an assumption nonetheless. Correlation in and of itself does not imply causation. [/B]

It's very difficult to see how the correlation can hold if there is not interaction between brain and experience. Leibnitz argues God maintains the link, but the idea never caught on. How do you think they are correlated if they don't interact? (Btw I'm not assuming anything about which direction the causation works).

(I agree with your last post. Good point about the conceptual being prior to the physical).

It's funny that you mention that, since I'd just been considering it. However, I think this reasoning is wrong. Introspection comes quite a bit after perception of objectivity, in the development of an infant, doesn't it?

What of the consciousness of a dog, that he has been approached? It can be said that it isn't really like anything to be a dog, since the dog never conducts introspection (note: I chose "dog" randomly, I could have used any non-sentient (not even semi-sentient) mammal), and yet he is conscious of objective phenomena, right?

Perception is a subjective experience, and so still belongs under the 'conceptual' category (again-- assuming by 'conceptual' we refer to the ontological nature of consciousness rather than the more literal definition).

I don't think we know enough about the mental activity of dogs to say that they don't conduct some sort of introspection. Regardless of this, your argument relies on the notion that it can only be like something to be a certain creature if that creature introspects, which can't be taken as a given.

In what sense can a dog be said to be conscious of phenomena if it is not like something for that dog to experience those phenemona? If it is not like something to be this dog, it follows that the dog has no subjective experience; if the dog has no subjective experience, it follows that it is not conscious.

I know what you mean about relying on third-person evidence. But if you think about it consiousness is completely invisible to third-persons, and in fact we rely entirely on first person evidence. What we see from a third-person perspective is behaviour, not consciousness. Alos, however much science we do we will never prove that emotions exist in a scientific sense. How is physics going to explain something it can't prove exists?

Actually, Psychology is considered a science (I think), and rightly so. It may only be able to interpret "behavior", but that just means that a full understanding of emotion will not come until a physical link to each instance of this "behavior" is found. Right?

Ah, but you agree with him.

Because I haven't noticed any of these faults that you point out. My "agreement" is different than most, in that it is merely a current assumption that I cannot yet disprove.

He did a pretty good job as well, but dualism lives to fight again. His book had little impact on the debate as far as I can tell from what emerges in the literature.

You are correct. That is sad, in my own opinion, since the new scientific theories of consciousness do seem to follow very near to exactly the model that he predicted.

He showed some forms of dualism to be illogical, but failed (imo) to deal with the more logical forms of it. (I also think that (ultimately) dualism is false, but only at the limit).

What "more logical forms of it" are you referring to? Examples?

Are you saying that consciousness depends on language? You wouldn't be alone in that (Wittgenstein agreed I think) but it's speculation with little evidence to support it, and plenty against.

Well, I say that the propogation of memes in complicated social structure is indeed dependent on language, and that the passing and personal propogation of memes is very important to consciousness...what's wrong with that?

Do you think that consciousness (our ability to know we are experiencing) is causal? It's not the scientific view. According to science consciousness had (and has) no effect on our technological progress.

Hmm...but no non-sentient being could ever invent the tools that primitive man must have used to outwit his predators and his prey (since we're not much, physically, compared to some of the beasts that existed 2 million years ago).

If you KNOW that subjective experience exists, but science cannot observe subjective experience, then how can subjective experience be the the same thing as a brain state. How do you know subjective experiences exist?

I told you, I know that they exist because I've experience them. You have too, otherwise you wouldn't have experienced whatever emotion it is you are experiencing at the time of reading this (hopefully only good thoughts ).
