conflating all forms of dualism into one is not likely to be helpful;
and, of course, it defeats the purpose of having a taxonomy in the first
place.

Searle, in trying to explain why he is not a property dualist, claims
that consciousness has an irreducibly first-person ontology; but, he is
not admitting to Cartesian style substance dualism.

in my opinion, Searle should have said that consciousness has and
irreducibly first-person phenomenology. that would mean only that he
accepts what I call phenomenological dualism -- the irreducible
difference between measurable phenomena and experienceable phenomena.

the point is that claiming that there is an irreducible phenomenological
dualism is to stand on dualist ground; but, it is not to stand where
Descartes stands.

similarly, to claim that this phenomenological dualism is explained by a
dualism of properties (physical objects have a set of properties that
explain measurable phenomena and some objects have a set of properties
that explain experienceable phenomena) is also to stand on dualist
ground; but, again, it is not to stand where Descartes stands.

it is only where you postulate a second type of metaphenomenal object
that you stand where Descartes stood.

Well you said I was presenting a "taxonomy", I didn't. I said I was presenting what I took to be the four options before us. I never suggested I wasn't generalizing and, indeed, my parenthetical remarks made quite clear that I was lumping a number of different instances into particular categories, especially with regard to option #1.

Not every point is best made by an exacting breakdown into every little possibility, especially when it would be overkill (going beyond what's needed) and therefore likely to add to confusion rather than reduce it. Does this mean confusion might still not result? Certainly not as seen here where you want to take me to task for not doing well something I did not say (or presume) that I was doing at all.

What you call "conflation" is only that if it means a relevant distinction isn't being recognized. But you have no evidence that it isn't, and, moreover I have referred to it and even explained why I contented myself with a generic summation of the possibilities. That's evidence of recognition if anything is.

Yes, I think Searle is confused on that point. I think he is using "ontology" in a different way than it is meant in cases like this though Walter and Larry (I believe) showed on the Analytic list that there is another way to use it, namely as the name for describing whatever exists on whatever level. In THAT sense, an ontology can be about all kinds of categories of things in which case we can speak, as Searle does, of first person and third person ontologies. But THAT isn't the way the term is used in terms of dualism vs. other theses. In that case, the issue is really one of reducibility.

While we can agree that first person and third person claims represent irreducibly different accounts applied to our actual experience (because they deal with different aspects of it), this has NOTHING to do with the causal question and even Searle agrees that consciousness is caused by brains. That is the only arena where dualism matters and it is in that arena that the question of ontology becomes relevant. So Searle confuses two different uses of this term in his effort to argue for the irreducibillity of consciousness without denying causal irreducibility to brains. It is, ultimately, an unsustainable position but it is so clouded with ambiguities that it is hard to unpack.

So you would recommend he use your vocabulary?

I agree with Searle that it is a difference without a difference. If it is dualism, whether you speak in terms of substances or in terms of properties, if at the end of it all you are talking about is two ontological basics, then you have the same thing. A rose by any other name . . ., etc., etc.

I think your distinction between measurable and non-measureable is a non-starter but if you can explicate it further perhaps I'll reconsider. For now note, again, my point that anything we can measure is therefore experienceable nor is it clear that we cannot measure, in some ways, anything that is experienceable. If I have a private experience, I can measure it against objectively observable occurrences, clocking its duration, say.

I think you are overly concerned with matching Descartes, metaphysical point for point. One can fall into the same way of thinking as he did without subscribing to his every claim or argument. Indeed, dualism, of the sort that informed his thinking, seems rather prevalent among humans, at least at one level.

Of course it is. Unless it's worse. Rorty covers this in that
introduction I mentioned yesterday.

Even in Searle's case.

I'm sure there is an irreducible difference between being in Boston
and being in New York, that's pretty much the kind of thing that
the generalized verb "being" is good for, indicating essentialistic
differences, whether reducible or not. But look where that takes
you, deep into the heart of essentialism, every particular having
its own unique essence. What is it like to be a bat named Barney

Re: The Epiphenomenalism of Dennett-Consistent Philosophies of Consc

Posted by: "SWM" wittrsamr@xxxxxxxxxxxxx

Mon Jan 25, 2010 9:23 am (PST)



Joe raised the question of whether Dennett's model implies epiphenomenalism, a claim I have denied. I took a little time to use the Internet to see what Dennett himself may be on record as having said about this. I found an interview of him that looks authentic (the words ascribed to him sound very much like him) though I can't vouch for it at this juncture. Nevertheless, assuming this is a legitimate record of Dennett, himself, on the subject, I thought I'd just let him speak for himself:

http://meaningoflife.tv/transcript.php?speaker=dennett

Wright: Ok well we should bring in another term to make clear what you're not. The term is "epiphenomenalist." An epiphenomenalist view of consciousness is that consciousness is generated by the brain so the brain influences consciousness but consciousness does not in turn influence the brain.

Daniel Dennett: Anything. Anything.

Wright: Anything. Right.

Daniel Dennett: And that is one of the, I mean, to this day I am flabbergasted that anybody takes this view seriously.

Wright: That's not your view?

Daniel Dennett: It certainly isn't.

Wright: Let me just go on. Epiphenomenalism is like...

Daniel Dennett: It's insane!

Wright: So consciousness is to the brain the way a shadow is to my hand as I move my hand?

Daniel Dennett: No. No. No.

Wright: That's what Epiphenomenalism is.

Daniel Dennett: Ah. Thank you. That's what people thing Epiphenomenalism is. And it's not. Your shadow is perfectly visible. It has lots of effects in the world. It has lots of effect in the world. There's a perfectly innocent notion of epiphenomenalism.

Wright: I understand that but as my hand moves along, the shadow does in turn not effect my hand. It is a limited analogy . . .

Daniel Dennett: It is a limited and very...

Wright: ... influenced by the brain but does not in turn influence the brain, that is epiphenomenalism.

Daniel Dennett: Well, but...

Wright: And you are not an epiphenomenalist.

Daniel Dennett: Right, because epiphenomenalism is exactly as absurd as the following view. Ready?

Wright: Ok.

Daniel Dennett: In every cylinder of every internal combustion engine there are seven epiphenomenal gremlins. They're caused by the action of the cylinder, they cause nothing internal. They are undetectable by any machine, by any test there couldn't be a gremlin-o-meter. They don't add to the horsepower, they don't add to the weight, they don't add to the mass. They are completely epiphenomenal.

Wright: What bothers you is that in this view, in the ephiphenomenalist view, consciousness cannot be detected by any scientific means.

Daniel Dennett: By any means at all.

Wright: Right. But you gotta understand it's detectable by the person's consciousness...

Daniel Dennett: No no no. No no no.

Wright: Yes! Trust me..

Daniel Dennett: No, that's the mistake because if that were true then you wouldn't be an epiphenomenalist because if the fact that you are now telling me that you detect your consciousness is an effect of your detecting it then your detecting it is an effect of the epiphenomenon and that's ruled out by definition.

Wright: Now you've gotten it. That's an interesting thing that I've thought about a lot...

Daniel Dennett: That's the problem with epiphenomenalism. It's an incoherent view.

Wright: Okay, but here's the interesting thing. I've thought about this a lot lately. That in the human species, even if you are an epiphenomenalist in this sense, you think when pain, subjective pain, arose in a lizard or in a worm or whatever, okay let's go back millions and millions of years in natural selection, subjective experience arose as an epiphenomenon. Ok. And you can imagine that, right? You can imagine that ....

Daniel Dennett: No I can't.

INT: ... a worm has an epiphenomenal consciousness.

Daniel Dennett: No I can't.

Wright: Why not?

Daniel Dennett: Because ... because ... I'll say it again, slower I guess. The very concept of epiphenomenalism, of effects that have no effects, is completely unmotivated. Always. Always. Always.

Wright: What does that mean?

Daniel Dennett: It means... You agree, I think, that the view that there are seven epiphenomenal gremlins in every cylinder is a view that is not to be taken seriously. Right?

Wright: It doesn't seem likely to be true.

Daniel Dennett: Well compare it to the view that there there's 6 epiphenomenal gremlins or 3 or 7...

Wright: Equally implausible.

Daniel Dennett: Not just implausible. It's defined in such a way that you could never possibly have any reason to assert it.

Wright: So it's not amenable to scientific analysis?

Daniel Dennett: No, it's worse than that. It's trivial in a certain way. There could be no motivation for asserting it.

Wright: If the engine said "I've got gremlins" I'd start taking it seriously. And that's what happens...

Daniel Dennett: If the engine said "I've got gremlins," one thing you would know is it couldn't be saying this because it had gremlins. Because if there were gremlins they wouldn't be causing it to say it because that would be a contradiction.

When people talk of epiphenomena, I don't think they are talking about
gremlins in the cylinder. Rather, they are talking about that carbon

Yes, I think they are thinking about cause/effect that flows one way but not the other. That appears to be what his interviewer was saying, too.

Dennett appears to be arguing that even awareness of the "epiphenomenon" means something is being caused but, of course, those who argue that consciousness isn't itself a matter of physical causation would not be obliged to acknowledge that just being aware of something is to have a causal relation flowing from the "epiphenomenon" to the aware subject!

But then this gets at the problem of competing models (consciousness as a monadic point of spiritual evanescence, light or what have you on the one hand vs. consciousness as a physical process-based system on the other).

One might want to say that Dennett's claim about the incoherence of the idea of epiphenomenalism hinges on embracing his idea of what it means to be a subject but that would seem to make his claim circular, i.e., once you see he is right you will see that epiphenomenalism makes no sense.

I expect he would not agree with my suggestion that it's circular though, but I am not sure he would be right in demurring.

I must admit that my instinct is to side with him here but, as I hope anyone reading my comments on the subject in these postings will see, my argument hinges on the difference in the conceptualizations rather than on a claim that epiphenomenalism is, itself, absurd. That is, I would say that the subject (what we consider ourselves to be) is a complex system which, even if it has observer parts with no direct ability to affect the world, as Joe puts it (the "narrative center of gravity"), that is not what we mean by the effective subject. The subject that affects the world is a complex one which includes causal physical components. My point is that, on this model, there is NO reason to imagine that we MUST have a stand-alone, pure self or consciousness at the center or core of what we consider ourselves to be for us to have a sense of being a self, being a subject.

If we can explain consciousness on this system model, then the fact that we see ourselves as subjects that stand apart from the physical (though which still impacts on the physical) is not evidence that something is being left out in a system model account.

What about Dennett's claim of incoherence then? It's interesting I think and might be right (it really might be all that needs to be said about this question, as he seems to be sayin in that interview) but I need to think it through more.

Evasive? He clearly rejects the idea entirely.

Well, I'm not that clear either just where he was going with the
gremlins. I mean, it's clear his objection is that epiphenomenalism
is by definition outside of any causal chain, but you are right,
it's usually at the end of the chain, leaf nodes, and the gremlins
seem to be upstream in the metaphor.

But Dennett's position is clear, he rejects epiphenomenalism as
a coherent concept, in W terms it has no place in his grammars
nor forms of life. I thought that Wright's role as an interogator
was obnoxious, clearly Dennett wanted nothing to do with the
concept.

This is where I become impatient with philosophy. It seems to me that
the problem to be solved is "what is the brain doing, and how does it
do that?" So I see talk of "spiritual evanescence" as an unneeded
mysticism.

The problem for AI folk is that their ideas as to how to produce an
artificial person do not seem to involve consciousness in any way at
all. And that's why they tend to be epiphenomenalists.

The problem for Jerry Fodor is that he sees intentionality as very
important. Yet his view of how the mind works (as discussed in his
"Methodological Solipsism" paper and in his "Modularity of Mind" book
does not actually depend on original intentionality at all. So he has
to be either epiphenomenalist or mystical about intentionality.

Searle's position is more complex, in that he rejects the
representationalist views of Fodor and of the AI folk. But I don't
think he is actually trying to explain what the brain is doing, so he
probably isn't considering any worked through theory.

I suppose my own view is a bit closer to Searle's. That is, I reject
the extreme representationalism of AI and of Fodor. That's why we got
into that long disagreement about finding patterns in the world.
However, unlike Searle, I am interested in what the brain is doing and
how it does it. Still, I am not trying to "design" consciousness. But
as I look at what I believe the brain to be doing, I see that it is
closely connected with consciousness.

My best guess is that Dennett really is an epiphenomenalist (as most
people use that term), and that he is attempting to construe
epiphenomenalism very narrowly in an attempt to evade that. But I
doubt that people will buy into his narrow construal.

I disagree.

Wright: So consciousness is to the brain the way a shadow is to my hand
as I move my hand?

Daniel Dennett: No. No. No.

Wright: That's what Epiphenomenalism is.

Daniel Dennett: Ah. Thank you. That's what people think Epiphenomenalism
is. And it's not.

Can't you see the problem there? To Wittgensteinians, who go by the
view that meaning is use, the idea that epiphenomalism can be different
from what people take it to be is just nonsense. Dennett is resorting
to essentialism. He is saying that there is an essence to
"epiphenomenon" that people are missing. So where does this essence
come from? Perhaps it is part of a mystical intentionality. Yet
Dennett has rejected that with his intentional stance. Or perhaps this
essence comes from God. But Dennett has stated that he is an atheist.

It seems to me that Dennett is being a spinmeister here, and Wright is
acting as he should to try to get past the spin.

The question you pose is the scientific one. The philosophical one is whether science is equipped to answer this particular question. It's a different kind of issue and it can be solved (at least theoretically) either by a straight forward argument to which others will agree (the traditional philosophical approach) or, in a more Wittgensteinian way, by showing why it is not a real question at all, generally by showing that it can't really be asked so if it can't, it can't be answered.

Some take the argumentative approach like Joe, on this list. In the philosophical community more broadly, we can put Chalmers or Galen Strawson in this camp. Bruce seems to me to want to have it both ways, by alowing that science can do something along the way of addressing this kind of issue but then insisting that what science can do is irrelevant to any meaningful talk about minds.

It seems to me that Dennett makes a case (if not quite a traditional formal argument) for science being the one and only venue for this and argues that this hinges on a particular revision to our usual understanding of consciousness (a position with which I am on record as agreeing).

Searle strikes me as more like Bruce here in that he argues that science not only has a role but can likely succeed except that his conception of consciousness appears to make that problematic because he insists on mixing ontological issues.

Not all the AI folks I have encountered. Certainly not the guy over in Switzerland we discussed off line who thinks that by replicating a brain in ALL its particulars on a computer he will also replicate consciousness (replicate, not merely simulate).

I agree on the matter of Searle and brains. While asserting that brains cause consciousness he argues that no one knows how and he has no idea either so it's a a kind of ongoing mystery and then he compounds this by presenting a picture of consciousness that looks like it cannot be reduced, in which case the only way brains can cause it is via a dualistic conjuring trick (an implication his many supporters seem to want to fiercely deny).

Yes we never resolved it to our mutual satisfaction and probably remain far apart on that point.

No, I certainly don't on the basis of the argument I've given about why it makes no sense to presume epiphenomenalism on the basis of Dennett's model.

Actually the issue is that he is saying epiphenomenalism, when you really think it through is simply incoherent. We can imagine all sorts of things but then, if we really consider the implications, it may turn out that we weren't really imagining what we thought we were imagining. His argument about the gremlins isn't about the gremlins at all, or the grease or the carbon deposits. It's about whether it can ever make sense to imagine womething for which there can, by definition, be no criteria for it. A term denoting such a thing only looks like it has a use, a grammar, but when you look more closely you have a case of language on holiday. So Dennett's point is indeed a Wittgensteinian one.

On the other hand I'm not entirely convinced that his case is open and shut here given the issue of whether one has to already hold his conception of consciousness to consider epiphenomenalism incoherent. If one does, then arguing for the incoherence of epiphenomenalism can be no argument FOR his model of mind.

Well, look, if epiphenomenalism is as empty a concept as Dennett
thinks, any analysis is going to be faulty.

But for most, consciousness is the main act. I don't think Wright's
analogy makes any sense. Dennett's answer is just the byproduct
of trying to engage gibberish.

But as we learn from the many discussions by our learned host here,
any term is empty. If there is some grammar to epiphenomenalism
that matters to anyone, let's have it, instead of third-derivative
example of hand shadows.

> Dennett is resorting
> to essentialism. He is saying that there is an essence to

No, Dennett never deals for a moment in essences, you are misreading
this. Dennett attempts to tell a story about mechanics, and maybe
gets it a bit scrambled with his demons, but putting a mechanistic
story in play is pretty nearly the polar opposite of an essentialist
story.

Forget Dennett for the moment, let me see if I have any of my own
perspective on epiphenomenalism, and ... well, following my own
advice, I don't. It's a ghost story, and I have no analysis of
my own on what ghosts are or are not. I simply have no place for
ghosts, nor epiphenomenalism, in my own theories, to paraphrase,
who is it, Voltaire, Laplace? Whatever.

Me, too.

Yet, I continue to find values in both.

Fodor says, "no computation without representation", but I believe
that is wrong. Certainly, neural networks compute, purportedly
without representation.

And (my topic of the week) Rorty too rejects the idea of mind
(or philosophy) as a mirror of nature, in that he is (apparently)
more instrumentalist about it all. I need to reread him before
saying more.

I think the case is that representation is often available and
convenient, but never necessary, in any sense of the term.

In which case, it is a project to revise Fodor in the light of
the contingent nature of representation.

Hawkins is on the wrong track. Edelman's main direction is very

That's a bit of an overstatement, Neil. After all, there are plenty of philosophers whose specialty is science and how it works. Moreover there are philosophers who are basically science-oriented (see Dennett). Moreover, the point of philosophy is that it is a different game than science.

Scientists study facts in the world, collect data about it, formulate theories and test predictions based on those theories against the data collected.

Philosophers consider the conceptual issues used by science and other disciplines, either through the application of logical analysis and argumentation or by exploring our linguistic usages (how we speak, and therefore think, about things).

Since they are different games there's no reason why the two sets of disciplines (and there are different schools of philosophy just as there are different field of scientific inquiry) need to be seen as poaching on one another's preserves. Thus science can study a phenomenon and philosophy can examine what it means to study that phenomenon, what the approaches to such studying ought to be, what about it is capable of being studied scientifically (if anything), etc.

His aim is to produce a virtual brain that does all the things real world brains do (albeit virtually) and his idea is that, if he does that, he will produce a consciousness in virtual space. His presumption is that a mind is just what the brain does and a virtual brain will be conscious, too. That is, his aim is to get conscious responses from a machine running a virtual brain.

Yes, of course. I am not sanguine about this approach myself but I would not simply dismiss it.

Yes, I know that is your position. I disagree. I actually have found his approach to be the most promising of what I have read so far, for all the reasons I previously gave.

> Edelman's main direction is very
> different from what interests me, and he isn't an easy read.

Right, he is not. I think that reflects the reality that he is not himself clear on this stuff and is therefore likely to be on the wrong track. Intriguingly, both Edelman and Hawkins align themselves with Searle vis a vis AI yet they each seem to have diametrically opposite reasons!

Edelman, a biologist, argues that the brain is too complex and therefore its algorithms are too deep and massively complex for any computer to match. (He argues that the underlying genetic coding is based on six basic units rather than a computer's binary system so that the combinations are greater, and that the brain's morphology is naturally much more complex and disorganized than that of any computer.)

On the other hand Hawkins, a computer scientist, argues that, because of its organic nature (carbon based chemistry rather than silicon based), the brain is just too slow to do what computers manage to do via massively complex algorithms so only a relatively simple, repetitive algorithm running in brains will be able to do the things it takes massive silicon firepower to accomplish in computers!

He has some interesting insights and hypotheses but no overarching theory at least as far as I have seen so far.

Explain the "relation" you see then between brain and mind and what it means for these two to be in an other-than-causal (existential dependence of one on the other) relation of the sort you think makes sense.

As I have said in the past, I don't claim you assert dualism. I claim that your arguments reflect an implicitly dualist idea with regard to minds and brains.

Anyway, I've spent a good deal of time saying what I think and defending my views (saying why they make sense) in response to plenty of critics here and elsewhere. Now perhaps you'll take the stage and tell us YOUR views on the matter and defend them against any critics who wish to challenge them?

I'm kind of tired of repeating myself for what seems like nearly forever on this question of how one can model mind in a way that is consistent with an entirely physical universe. Maybe it is only right that it be your turn now.

If Dennett had properly understood science, he would not have got into
that public debate with Stephen Gould over evolution.

So do historians, accountants, journalists. The description omits what

That emphasis on logical analysis and argumentation is perhaps why they
miss out. Science is very prolific in coming up with new concepts, and
philosophy does not seem to study why or how. Perhaps it doesn't even
notice.

The underlying problem for science is that of understanding the world
around us. The underlying problem for the brain is that of
understanding the world around us. If philosophers really understood
how science works, then they should have little difficulty extending
that into an understanding of how the brain works.

Wittgenstein on Religious Belief

Posted by: "gprimero" wittrsamr@xxxxxxxxxxxxx

Mon Jan 25, 2010 6:37 pm (PST)





Do you interpret Wittgenstein´s views on religious belief as a kind of "religious non-realism"?
The author of the following article describes some types of religious non-realism (e.g. religious positivism, religious expresivism, religious instrumentalism, religious fictionalism), and their differences in relation to the standard religious realism:
Eshleman. (2005). Can an atheist believe in God?
http://ualr.edu/philosophy/assets/believe.pdf
Could we interpret Wittgenstein´s views about religion as any of those types of "religious non-realism"? If so, which one? Otherwise: why not, and should we interpret his views instead?

Sorry, when you wrote "explanation of the physical organism" did you
mean to hold that distinct from the person's mental life? If so, then,
of course, physical events cause physical events, whether they be of the
heart or brain.

But explanations of "behavior", as I understand it, can't be fully
understood in terms of physical factors. Two people see a sunset, two
people may have radically different accounts.

It's that transition from the physical to the mental, what SWM recently
called animating the physical is problematic.

All that aside, I would agree if you asked your question like this: Why
isn't any explanation of behavior in terms of influences (genetic,
historical, etc.) be sufficient?
