Design Inference and Mind
This is a topic that's been bothering me off and on for a while, I've written a few posts on it and then deleted them. Even before I declared that I was leaving message boards I was trying to get a post done on this. Anyway, since I always change my mind on how to approach it, let me just cut and paste this email I sent to Elliot Sober yesterday: Dr. Sober,
I've read a number of your papers online and your arguments against Design Inference resonate with me more than others I've read. I'm also quite interested in phil. mind. For some reason, "I", keep thinking eliminativism is my only option if the argument works that we can't (in theory) know anything about the content of alien (or computer) minds or even if they have minds/intentions. It seems to me that if there is some kind of ultimate structure to mind, whether it's neuro-chemical reactions or functional relations, then an alien with that would have mental content translatable, ultimately, in human terms. In other words, if humans could come up with a geneneral case model of the mind, we'd be able to reduce all langauges to little thought-bit representations. We'd then have a general theory of language. And if we had a general theory of language/signification, we'd have a prior pattern to compare space signals to. And then we'd be able to test for "specified complexity". Ok in practice I'm sure never, but as a thought exercise, it seems that way to me. That any atomistic theory of mind would at least weakly validate, in principle, the idea of "specified complexity".
thanks for your part in bringing sanity to the world. -- Given I didn't ask permission to post his response and that his reply was very thoughtful, I won't post it but I'll just give my interpretation of what he said. First of all, it might be helpful to get Sober's take on the "other minds" problem generally, not specifically related to DI: http://philosophy.elte.hu/colloquium/2000/Marcius/Sober-paper.htm In his response to me he left the ID stuff out completely and concentrated on elimitavism. If I understood him correctly, he thinks eliminativism is too extreme because we could say the same thing about life, throw out the concept of life because we might not one day be able to identify whether something is alive or not. The problem I gather, in his view, a matter of epistemology only. But I can't quite figure it out whether he means there is no way to interpret mind from behavior in extremely foreign cases or that it's possible in theory, but we need some ingenious invention. The second seems to me to still allow DI as valid in principle, the first may or may not. I'm sure his view is consistent and I just don't get it but I don't want to keep bugging him. That would be like asking God for the same toy over and over again, he has better things to do. Other solutions may be in assuming too much in my argument. For instance, part of my argument is rooted in Quine's observations and his move from language non-translatability to elimitavism. Perhaps there is a way that thought atoms exist but don't give rise to a universal language. Well, there could be questions like that at every step of my argument. I had another thought just today on the matter though. Maybe externalism would help. If that sounds obscure, take a look at Putnam's Twin Earth Experiment: http://artsci.wustl.edu/~philos/MindDict/twinearth.html I probably should have thought of this before, but anyway, in externalism, mental content depends on things external to the individual. So it would be impossible for humans through introspection to reverse engineer mental content and derive a general case, the secret to language (if it makes sense to even call it that) would forever be part of the Ontic world. After a couple quick searches I can't figure out if Sober is an externalist or not. Another possibility is I'm reading too much into Sober. Maybe he believes DI is a theoretical possibility but well beyond our abilities, and that Dembski's problem is making too many ridiculous assumptions about what we know in order to make a science out of it that gives us the results IDers claim.

Topic: Mind
There is a broad range of thought seeking to define qualia, from non-existence, to basic feelings like pain, to even broader experiences - what it's like to win a footrace or be a CEO. The problem - and it's a perplexing one - is that there might be two things in the universe instead of one. It's a problem, because on one hand science has been so good at explaining things we'd hate to just give up and say, alright, everything in the universe has an explanation but we're going to make an exception for this one "thing," mind - especially the definition that turns on "what it's like" to be something. Mind is the last little corner of the universe anyone with any credibility might conjur up a dualistic story about. And it doesn't seem like we can just shrug off the problem and declare victory for physicalism. The feeling of pain is clearly not a material thing like a rock or a tree. How to deal with it? My gut instinct is that the problem of mind is as much of a problem for language as it is a problem of ontology. That's certainly not an original thought, philosophers from Dennett to Searle complain about how philosophical language makes the problem that much harder to deal with. A key issue, it seems to me, is that of referance generally. Take the Leibniz thought experiment of walking through the brain. We can walk through the maze of mechanical functions and never see a pain or a thought. This supposidly shows that thoughts and mechanical things are of two different kinds. A succinct reply to this from Rorty goes along the lines that, indeed, Mayan script is also meaningless to convey Mayan concepts unless one speaks Mayan. It's not inconceivable then, that we might one day understand brain language and "seeing a thought" won't seem so ridiculous. We must also concede that language, even the language of science has evolved over time. What does the word "quark" really refer to? How about "gravity?" The language of science has become increasingly more abstract over time and what the brain is able to cognitize as familiar e.g., familiar in the way simple expressions in one's own langauge is familiar (which are also incidently, often the most untranslatable and meaningless on a realist's account), has changed. The abstraction of relativity at one time pushed the imaginations of reputable scientists but today, is readily grasped by bright young undergrad students. So I don't think there is an open and shut case for the failure of "science" to be able to account for mental content, qualia specifically, or even "first-person"-ness. But I think to maintain this view, one has to be flexible on how language works and take a view in the direction of Quine, Wittgenstein, and some of the Continentals. What the future might hold seems more foreign than it might really be, and what the present holds might seem more natural and 1 - to - 1 in correspondance with the external world than it really is. And sure, I use those "really"'s loosly. All of this doesn't mean I think the matter is settled or even close to being settled. I just don't think with the arguments currently on the table for the "hard problem" hands down secures us a dualist ontology, or even one that requries a clear disctinction between the "first-person" and "third-person."

Fading Dennett?
Topic: Mind
I'm going to get back into this blog. Life is becoming a *little* more normal again and some of the otherwise message board time I'd have spent circling around the same-old I've been able to put into reading an article or two here and there. I don't have anything incredibly insightful to bring up but maybe I can dip my toes into some trivial stuff to get back into things. I might also, shortly, begin allowing comments. The only problem I have with that is managing spam and so on. I was in the bookstore a couple weeks ago and stumbled accross a new book by Susan Blackmore, "Conversations on Consciousness." It's pretty basic reading and I got through about a third of it there in one sitting. I think it might be worth having given the number of entries from scientists and philosophers in the field for novices like me, but I'd buy it used from amazon. The most interesting thing I read - and unfortunately I can't recall the guy's name - was a particular scientist who specialized in optometry and thinks they've found the seat of consciousness accross a piece of the visual center of the brain. What made his idea interesting, though (and I'm really hoping I'm not confusing his piece with another article in the book), was his idea that some people might experience consciousness more or less intensively. This was brought up as an explanation as to why Daniel Dennett might be so ready to reject the existence of qualia. HAHA. I couldn't believe it. Funny thing though, is that John Searle has made a similar accusation against Dennett, and I've seen other accusations on the web that Dennett might just be a "philosophical zombie" (a being that passes the Turing test without any inner life). The first thing I thought of are the Christians who, following Plantinga, accuse athiests of possibly being defective and lacking a proper Sensus Divinitatis. Funny that even those at such a high level are willing to suppose some kind of cognitive defect to explain an opponent's position (I'm sure Dennett has his own equivalent invective.) Dennett, for those who just kind of hear his name as linked to dogmatic atheism on the web, is a very well-rounded and talented guy, not just an attack dog for what some would see as nihilism. In addition to being an Oxford Phd at 23, he's a jazz musician, a near professional sculptor, and for years sang in a classical choir. An expert downhill skier (in his youth) and sailor too - let's not forget atheletics. Just my own intuition here, but it would seem to me that if there were those who really didn't have a keen consciousness, such a circumstance wouldn't be tied up with such a wide range of abilities. I'd expect that, if it's really something that happens, for it to correlate more with Asbergers or something. Anyway, more on my frustrations getting a handle on the issue of qualia in the next post.

Sociology of Knowledge
Now Playing: To Be Edited!
Topic: Lectures On Doubt
Knowledge as a social institution is most certainly an idea that most atheists aren't going to have much patience for. The typical fear, and in some cases for good reason, is that what's being argued for allows anything to become knowledge so long as everyone believes it and that there is no world external to our minds. Of course, many religious folks in all their simplicity really latch on to this idea because they think it means that if a lot of people believe in something nuts, like their God, then it must be true. This is similar to the tactic I've discussed before about Christian penchant for radical skepticism when they're backed into a corner. I tried to argue in favor of constructivism as an experiment on FAIR the other day, sort of an unconventional angle to take I know, but then again, why not deny them of their belief that if they can get rid of the enlightenment their problems are over? Now, I really don't have it in me to do a technical post tonight. Maybe that's a good thing, keep it simple to understand, and me from stumbling over myself. I pick Kuhn for my example here because he's relatively well known and he himself or some variation of his "paradigms" are invoked all the time by religionists who are trying to save their beliefs by making them a "paradigm" without a common ground shared with today's science establishment whereby they could ever risk being wrong. Well, according to Kuhn, not any old idea with a following qualified as science. Science in fact, was a relatively recent phenomena that required a high level of organization to acheive. A science has an extensive core body of research that everyone agrees on and those working within normal science should strive to work within the paradigm. So not just any rogue professor with a website and an ax to grind against the institution "has a paradigm." It would be difficult to argue that even a large body of informal researches united in more or less the same cause could have a paradigm. Paranormal studies are a good example. In a later post, I might fill in the details on why I believe that. UFO studies are something I follow and fit the bill perfectly I think. I need to emphasize something I said above. According to Kuhn, researchers should stick with the paradigm. One of the things very troubling to the enlightenment was the opressiveness of religion, and even with the huge success of science as an institution in today's world, the enlightenments glowing ashes are no less concerned. That way of thinking holds out for an ideal where nothing is sacred. Where the institution can never put to death another Galileo. Where the lowliest waif can revolutionize the entire institution overnight given a profound discovery. But the problem here is a practical one. How many straws of hay do we have to pull out of the bail before we draw blood? Shout's like Feynman's "Science is the belief in the ignorance of experts" seem to assure us that never again will superstition and beaurocracy stiffle progress, but in practice, how much sense does it really make for a large, complex institution to proceed like that? The downside is that pseudoscientists, apologists, and downright cranks LOVE this philosophy! Because to them, today's science is the church and they're justified from the outset to apostatize. Now we might sit back comfortably and say fine, let them bring the evidence! Well, the problem with that is, bringing in extraordinary evidence for review is hard to do even within the establishment. It's not as simple as providing a literal smoking gun picked up from the crime scene. Testing ideas often require funding. Giving research a fair hearing and reviewing the evidence also takes time and costs money. None of this stuff happens in a vacuum where only pure truth zips around as an eternal constant. All those voices challenging the status quo demand to be heard. But if evolution is our goal, giving them all a fair shake would be akin to being open to every mutation, fragmenting the herd and winding up with genetic drift, loosly interconnected colonies of mutants that are doomed to die rather than a stronger species. Kuhn recognized this problem and was therefore, against science as open to all ideas. Revolutions would come, but not everyday or from just any source. As new discoveries are made within normal science, evidence would eventually surface that doesn't fit right, leading to a crisis and a need for possibly a new framework. I brought up John Gee's apologetics for the Book of Abraham on a post a couple months ago. Gee has invoked Kuhn in the past to make the point that Egyptology might not yet be ready for the Book of Abraham. While it may hypothetically be true that someday the BOA might be vindicated, Kuhn's position would actually be that Gee's apologetics are counterproductive to science - he should be doing "normal Egyptology." And further, Gee's research couldn't really be properly considered science. Whereas from the enlightenment heritage, it's tougher to rule him out of court without sitting down and carefully reviewing his, and every other fringe researcher's, "evidence" and giving him a fair hearing. That ended up being kind of a long post. To sum up the scope of what I'm trying to say, a lot of atheists when they think of Kuhn or more broadly, any philosophy that considers science a social institution, they think of backs turning on reality. Well, that's a valid concern that I obviously don't have room to talk about in this post, but that's only a small part of what constructive theories are trying to get at. The truth is, and it's ironic for some apologists, that constructivists ideas can actually guard science from the dangers of religion and crackpots better than traditional enlightenment ideas, in some ways at least.

Moral Relativism
Topic: All Is Permitted
The typical arguments I've had with Christians online - and there have
been many - have been pretty superficial as I've discussed in previous posts.
The typical Christian has plenty of roadblocks preventing her from
pursuing an avenue that involves actual thought. The usual form of the
discussions I have are an exercise in trying to get the Christian to understand
that if the criteria must be "absolutist" or "objective" morals then atheists
aren't necessarily worse off than theists. The reality is of course, I'd wager,
that atheists are less absolutist and objective on the whole than Christians
are, but that's only because they are serious about understanding a complex
issue rather than just throwing out whatever conceptual framework is necessary
to assure that whatever they believe at the time is right and can't be
questioned.
"Absolute" and "Objective" often mean the same thing in ethics though you
could separate the terms to mean "fixed" and "external." There are cases where,
for instance, ethics could be external and variable. If you've happened to read
my posts on structuralism (or are already familiar with the idea), it's easy to
see how, if the thought of two societies are different and if one is more or
less bound to the thinking of their society, that ethics would be externally
bound to the collective resources of society but variable in that the collective
resources of societies differ. I'm not saying I buy into this, but I think it's
interesting to think through the problems if it were the case. The problems
would actually be I think, not as bad as people imagine. The biggest fear of
course, is that if morals aren't "Objective" then they could be anything. Of
course logically speaking, any given number of things could be different than
they are, but they aren't. Without some articulation on the driving force which
would make them be anything, then I see no serious reason to accept that
accusation blindly. It's logically possible for there to be 100 foot tall
spiders but there aren't. And if the hermeneutical point holds that cultures
don't readily translate into each other, then it does no good to say, "Aha! See,
those guys over there get to cheat on their wives so I'm going to be one of
them!" Since one wouldn't be thinking through the "cheating" in context of the
other society's thought structures, then it would be impossible to pull
off. So the egregious feats of reckless abandon in the name of technicalities
aren't at least, pulled off trivially if a thought-through version of moral
relativism holds.
Again, I'm not saying I believe all that. And even if I did, then I'd be
willing to be a little whiggish and force my values on a society that has a
tradition which looks an awful lot like child prostitution. At any rate, our
desire for objective morality is rooted in our desire to have the greatest
reasons for taking morals seriously in our own lives as well as in other's. But
there is also a pull from moral relativism to be practical. I mean, even if
we're not prepared to view acts within ancient cultures as moral, most of us are
at least willing to allow for mitigating circumstances. What for instance, can
we really consider to be a reasonable expectation for a Neanderthal? For only
the most naive is negotiation out of the question, and they are the ones who
will typically have some kind of silly notion that the Bible has enforced a
consistent objective ethic on man from the dawn of time. Which is of course an
outright laugh. Moral positions within the Bible and within the cultures which
have relied on the Bible have been as variable in their ethics as just about
anyone else. The reality of the situation is that we should all be a little
confused about what's right and what's wrong. Because if there is a danger that
relativistic assumptions will undermine the continuity of good, there is also
the danger that absolutist assumptions will tempt us into immortalizing bad. In
the balance I'd guess the latter has historically been the greater problem,
despite the vivid imaginations of the religious right.
A final comment on relativism. One of the thought-terminating arguments
against the very consideration of relativism is that - as virtually every
Christian on the net who's never studied ethics for more than five minutes can
tell you - relativism is self-refuting. If all is relative, then so is the
utterance, "all is relative." Of course, all we have to do to fix that is to
say, "all is relative except for this." In any case, this is more of a problem
within logic regarding self-reference that unfortunately reveals itself in
language use generally. Self-reference is a significant problem where naive
set-theoretic assumptions reign (where there are no restrictions on what can
belong to a set) and so logicians try to find ways to plug that hole. The most
well-known fix being Bertrand Russell's theory of types which essentially just
disallows self-reference. I'm not arguing that Russell's controversial idea is
true, that's well beyond my qualifications to even have an opinion, but I'm just
pointing out that the work to fix problems in logic fortuitously salvages
relativism from being self-refuting. The point is that true or false, the
suggestion to delimit the sentence in question isn't just an ad hoc
ideologically driven one set out to make the truth anything we want.
