Irreducible Mind fills a much needed gap

My review of Irreducible Mind is out with the latest issue of Skeptic.
I will post the review somewhere in due time, but for the moment I just want to make a few comments about this book, from a slightly different angle than what I say in the review. It's a negative review, of course, but there are good reasons to be even more scathing and angry at such a book (which is exactly what I plan to do here). This is all the more so that Irreducible Mind (henceforth IM), as far as I know, only had positive reviews until now, and only in pro-paranormal venues. (see here, here, here, here, here, and here). There is actually one review of this book I think would be worth reading, but I have no access to the journal in which it was published. This is the following:
Cardeña, E. (2007). The truly astonishing hypothesis. [Review of the book Irreducible Mind]. Edward F. Kelly, Emily Williams Kelly, Adam Crabtree, Alan Gauld, Michael Grosso, and Bruce Greyson. PsycCRITIQUES—Contemporary Psychology: APA Review of Books, 52 (No. 49), Article 5. Retrieved December 7, 2007, from the PsycCRITIQUES database.

Well, if anyone has access to PsycCRITIQUES, feel free to send me one copy. Otherwise I'll just ask Etzel Cardena myself one of these days.

So yeah, this book was increasingly being presented, in woo woo land, as a sort of upcoming revolution in the humdrum universe of sheepishly mainstream psychologists and neuroscientists (who are mainly materialists by default, obviously not realizing the inconsistencies of such an obsolete position, stupid as they are). You see, mainstream scientists (i.e. not crackpots) have failed to provide evidence that the brain is at all involved in the production of consciousness and mental states. What IM shows however, through more than 800 pages of marshalling irrefutable evidence, is that the brain merely transmits consciousness. Or filters it (whatever that means). So there is a conflict, you see, a controversy between the productive theory, and the transmissive theory of mind-brain relationships. Isn't that great? Every side of the debate has something to bring to the table, and boy, do scientists looove a cool controversy to resolve!

This is of course ridiculous, there is no debate at all. But the "transmissive" "theory" is actually taken absolutely seriously by a number of people nowadays. Mostly crackpots, which we'll meet again and again on this blog. Nonetheless, this idiotic "theory" is totally legitimate,we are told, because William James himself held such a view. William James! That's an impressive endorsement, of course, but it doesn't really tell us what the "transmissive" approach is actually supposed to be, does it? Surely the explanation is somewhere in the book. Well, unfortunately, it isn't, and it is clear that the authors don't care at all about what exactly this "transmissive" theory really entails. And this is the crucial thing to realize about IM and the agenda behind it. It's just like the Intelligent Design creationist movement feels no need to explain what "intelligent design" actually is and how it works: the authors behind IM don't need to explain what they think is being "transmitted" through the brain, how it is being "transmitted", and from where (note also the coincidental use of the word "irreducible" in the book's title, maybe that rings a bell). Well, theory and mechanisms are just not the point of Irreducible Mind anyway. The real point is to somehow acknowledge the discoveries and fabulous progress allowed by the neurosciences and related disciplines (only an idiot or a liar could do otherwise), while at the same time saying that this is "not the whole story". In other words, the materialistic-reductionistic model is not as wrong as it is incomplete. By doing so, you can still allow your healthy dosis of woo, soul-stuff and Jeezus into the equation that was built by serious and hard working people, and someday, hopefully, maybe get students to learn about the controversy between psychical research, religion and actual science. This "not the whole story" thing is an extremely effective (and boring) ploy that I encounter again and again. There is not a single argument in the world that cannot be complemented, if not refuted, by the very cheap statement "you might be right, but this is not the whole story". Hey, you can actually write more than 800 pages with such a brilliant strategy. The deluded love it, as it's not really important that they don't have the whole story either. They simply like it when they don't understand something, which is why psi believers make so great scientists nowadays.

Well, that's the message, folks, there's nothing else in there. The authors of IM are simply deep into the explanatory gap, up to their neck, and they have no idea of how to get out. Nor do they really want to, of course, for it really feels good down there, it's all cozy and warm, bathing in your own tedious imaginary world, full of ignorance and smugness, without actually accomplishing anything of value in the real world. Mental causation, yeah, that's the problem we're told, that's the real issue. You cannot explain it without woo, and, well, you cannot explain woo without more woo. That's all there is in the book, and it can be formalized as follows:

Explanatory Gap + Psychic Phenomena + Tribute to Frederic Myers = Quantum Babble + Whitehead

Don't ask for more theoretical details, there aren't any in the book. Overall, it really reminds me of the title Richard Dawkins gave to the final chapter of The God Delusion: "a much needed gap". Apparently, as Dawkins found out, it is not uncommon for book reviews to state things such as "this book fills a much needed gap". While this is of course funny, it actually does apply perfectly to IM. Indeed, its authors need the gap they have made up, as their main business is to pretend there is a need to fill it.

There is much more to say about IM and its authors, but for the moment try to grab a copy of the current issue of Skeptic and read my nasty review. If you don't have access to that excellent magazine, ask me for a reprint.

One last comment, something else about the "transmissive" theory. I've noticed that my fellow infidel and NDE-realist Keith Augustine has been caught in a discussion of this very idea. You can read it there in the comments, although I wouldn't really recommend you spend too much time there. The point is that Keith tries to defend the "productive" theory against a horde of believers, and in doing so provides an analogy he thinks might be effective in conveying the fallacy behind the "transmissive" theory. It all started with another analogy involving the Mars Rover, and here's what Keith wrote:
"Perhaps an analogy is appropriate here. Let's say we have two separate, interacting things: A Predator drone and the remote pilot controlling it from a distance. The drone is captured and its captors start fiddling with its transmitter/receiver. What's the worst the captors can do to the remote pilot, miles away? They can destroy the drone's camera, making it blind. The person controlling the drone will no longer be able to see the environment around the drone. They can destroy the microphone, making it deaf, and again, the radio controller will no longer be able to hear what is going on. Ditto if the wires connecting the camera and microphone to the transmitter are severed. Information from the senses has been cut off. Next, suppose that the wires connecting the receiver to the drone's engines are severed. Now the pilot cannot even blindly control the drone. It seems inescapable to me that any form of substance dualism is committed to predicting that the mind (the controller) is largely independent from the brain (the drone's transmitter/receiver). The worst you can do to the controller by manipulating the drone's transmitter/receiver is make the controller deaf or blind regarding the drone's environment, or unable to move the drone. You cannot affect the the controller's ability to do math, to understand language, or recognize undistorted faces. You cannot get the controller to go into a psychotic rage by manipulating the drone's radio. But you can make someone psychotic by spiking his drink with PCP, or prevent him from being able to do simple addition by lesioning certain areas of his brain. In short, basic neuroscientific facts are simply inexplicable on any variety of substance dualism."
Well ok, sure. But this is a convoluted way to address a simple problem. Indeed, the "transmissive" theory is unwarranted simply because it is useless to account for the facts. It is an inacceptable violation of Occam's razor, and the only way to address it is with similarly idiotic explanations. What causes crop-circles? Well, there is evidence that some of them are human made, but this does not mean that aliens, from their spaceship, have not taken control of those humans in order to produce their oeuvres. I call this the "middleman" theory of crop-circles. Show me the evidence against it. (it's fun, you can apply the unnecessary logic of the "transmissive" theory of mind-brain relationships to just about any theory or event or fact observed in the real world, try it for yourself! Quine would have loved it!).

5 commentaires:

  1. I agree with you that even playing the proponents' game, the grounds for rejecting the transmissive hypothesis are ultimately Ochkamist, as was the conclusion reached in that Rovin' entry. Note that I was testing out the "dilemma argument" I gave there to see how transmissive defenders would respond to it. The reasoning is not much different from what I have said before on the issue, but the idea of phrasing it in terms of a dilemma had only occurred perhaps a week before starting the first comments there.

    At the most basic level, though, the issue isn't an issue of mere simplicity, at least in the sense of saying production only postulates a brain, whereas transmission postulates a brain and immaterial mind, and so is less simple (i.e., two things are less simple than one). It's not simply that the immaterial soul is an unnecessarily entity, like the car engine demon, that one needn't invoke to explain how minds or cars work. It's that the immaterial soul couldn't even explain how minds work even if we did postulate it.

    That's an even stronger reason for rejecting transmission, and I think it important to bring them out given how people like Neal Grossman can cite William James as if he were the final word on the subject, paying no mind to whether James' "solution" would actually work or not.

    Even if we grant that there are these two radically different parts to a human being, the sort of dualism which would allow personal survival (and let's face it, that's the only kind of dualism that matters to most) still could not account for the facts of neuropsychology. At least not without the need to invoke ad hoc corollaries that make the transmissive hypothesis even more implausible than simply postulating some external immaterial element to human beings.

    Nevertheless, I think it useful to demonstrate how many ad hoc corollaries one must add in order to account for the same neuroscientific facts as the most straightforward explanation of those facts. Indeed, I think your analogy is right on the money: Proving that crop circles are man-made does not prove that aliens are not directing the behavior of the humans making them! If that's how far you have to go to defend your alien-caused crop circles theory, that's even more pathetic and implausible than saying that aliens directly created them.

    I think we have a similar situation with the dualistic survivalists in that Rovin' entry. Their solution is basically, yes, the brain does all of these things when alive, but perhaps "the soul" comes to use some other brain after death. As I said, you might as well postulate bodily resurrection at that point. The whole point of the soul hypothesis is to explain how it is that we have the minds that we know directly, here and now. When proponents give up on that and postulate some other kind of mind we might have postmortem, they are in essence conceding that the soul is not only unnecessary to explain our "embodied" minds but that it can't explain them even if we grant that there is such a thing. They are conceding that the brain in necessary for the minds we know about! What more is there to say at that point? Postulating some secondary brain that takes over what the "organic" brain has done all along is the equivalent, in my view, of postulating aliens that direct the behavior of the humans who make crop circles. Sure, it's logically possible, but it certainly isn't a very plausible view to hold.

  2. Hi Keith,

    happy to see you here! yes, I've succumbed to the blog mania..., I was waiting to flesh it out a little bit before I told anyone, but you're too quick!

    About the transmissive "debate": first of all I'm happy you like my crop-circle analogy, I'm quite satisfied by it I must say. I understand what you were aiming at with your own analogy, of course, but my concern is that it starts by conceding Prescott's choice of arms, and then unfortunately you end up having to account for a controller, a distant planet, a robot, a remote control and so forth. This is all useless and distracting, and the reader then thinks YOU are the one adding implausible and far-fetched factors, when of course the matter simply boils down to UNDERSTANDING the facts and implications of neuropsychology.
    The findings of clinical neuropsychology and neuropscience in general are of course widely accepted and reasonable data, totally unlike anything involving cross-correspondances, peak in Darrien, hauntings and what not.
    I admire your efforts at explaining and your willingness to convince, but frankly my approach is simply to mock these people and their "theories", as I don't think this is an honest intelectual debate at all. Biologists cannot TEACH evolution to creationists. Likewise, there is no point in explaining binocular rivalry, split-brain, blindsight, aphasia, synaesthesia and so forth to dualists. To paraphrase a famous saying, everything in neuroscience and neuropsychology makes sense EXCEPT in the light of the transmissive hypothesis. I would go that far.

    You write: "It's not simply that the immaterial soul is an unnecessarily entity, like the car engine demon, that one needn't invoke to explain how minds or cars work. It's that the immaterial soul couldn't even explain how minds work even if we did postulate it."

    Exactly, this is so obvious to me that I sometimes easily overlook it. In my review, here's what I wrote about this: "Where does this “mind” come from? We don’t know, maybe it’s
    turtles all the way down." But I realize now that this reference might be too obscure for some readers. In any case, it is clear that the transmissive hypothesis not only leads to an infinite regress, but still cannot account for the facts EVEN if we grant that regress. The situation here for the believer is even worse than for the question of evolution. Whereas we could perhaps grant that a really bizarre and whimsical intelligent designer is behind all life forms as we know them, say from a theistic-evolution perspective, no "soul" worth fighting for can ever be reconciled with the empirical data available now (and imagine in 20 years...).

    Another thing that catched my eye in your comment:
    "Postulating some secondary brain that takes over what the "organic" brain has done all along is the equivalent, in my view, of postulating aliens that direct the behavior of the humans who make crop circles."

    Well, I think it is in his book on "bilocation" that Bozzano postulates the existence of an "astral brain" (I can look up for the actual quote if you're interested). This was in 1934 I think, do you know of any other examples of believers resorting to "phantom brains"?

    In any case, perhaps we should list somewhere the number of concessions survivalists have to make and have made in light of findings of the neurosciences they could not ignore, from an historical perspective. The soul is not what is used to be anymore...

  3. A colleague pointed out this essay to me, which makes similar points, only directed at a Christian dualist who tries to have his cake and eat it too:

    http://www.beretta-online.com/articles/philosophy/hasker1.pdf

    That is, Hasker tries to have his postmortem survival via a soul even while conceding that the "soul" requires a brain to "sustain" it.

    By the way, notice how close you came to making the Freudian slip "neuropsience." Yikes! :)

    You wrote: I don't think this is an honest intelectual debate at all. Biologists cannot TEACH evolution to creationists.

    I worry about the risk that responding to the believers gives them credibility they might not have otherwise. But there is a greater risk in ignoring them, IMO. Look at how widely cited Pim van Lommel's conclusions are, even though they do not follow from his data. The evolutionary biology analogy isn't really applicable, though, because whereas biologists are often outspoken that creationism has been falsified by the evidence from evolutionary biology, neuroscientists are not generally as apt to say that the existence of a soul has been falsified by the evidence from the neurosciences, even though they think so. This means that the believers often say whatever they want, and what they say usually goes unchecked by those with the requisite scientific expertise to comment on the issue more authoritatively.
