Dembski: “I’m not denying evolutionary gradualism, challenging common descent or Natural Selection” (!!!!)


  
William Dembski has something to teach us; pity he's not being listened to!

The above Utube is a talk given by Intelligent Design proponent William Dembski. Unfortunately the sound quality is poor, and I had difficulty separating Dembski’s voice from a background rumble. Nevertheless I think I picked up the salient points, (But don’t quote me! Normally I go through videos like this two of three times, but I couldn't take the ear strain for a second hearing!)

I’ve always thought of William Dembski as a very intelligent and reasonable person. Although he probably classifies as an evangelical Baptist, he’s a moderate and a big point in his favour, as far as I’m concerned, is that he has been criticized by at least one fundamentalist for holding an old Earth position and also for being .....wait for it…..a theistic evolutionist. Referring to Dembski as a theistic evolutionist may actually be justified because in the video he says this (I think!):

We are Not denying evolution or limiting its role as an immediate efficient cause (at 51:50)…….I’m not challenging common descent, not challenging evolutionary gradualism, and not challenging that Natural Selection is the principle reason organisms have evolved (at 55:10)

This may come as a surprise because Dembski is an influential figure amongst what is often a vociferously anti-evolution community. Moreover, he isn’t exactly on the best of terms with theistic evolutionists like Ken Miller, Biologos and the Faraday society. Dembski has also been cold shouldered by the academic community as a whole: As he says in the video: 

 When I first published on the subject of Complex Specified Information I had no problems; it was only when I connected it to evolution that my career went down the toilet!

It seems that William Dembski is to the established academic community as he is to the fundamentalists – a heretic! But just what academic heresy has Dembski committed that theistic evolutionists like Christian Ken Miller et al. haven’t?  One of the problems seems to be that Demsbki, from an academic establishment standpoint, has fallen in with the “wrong kind” of people; in fact he has been taken on board as an intellectual champion by a broad church community that includes a strong contingent of anti-evolutionists who use his ideas to promote their agenda.

But I don’t think this is the only reason why the academic establishment is uptight about Dembski. The other reason is rather subtle. Paradoxically, although Dembski seems to be comfortable with evolution, evolutionists are not comfortable with him. So what’s going on here?

***
I’m of the opinion that Dembski has an important lesson to teach us, as I implied four years ago when I first looked at some of his work. Dembski has rightly pointed out that complex ordered configurations like living structures are, in absolute mathematical terms, a tiny class of configurations lost in a huge search space. If evolution is to work in realistic cosmic times that search space must be considerably narrowed down, a priori. Ergo, it follows that evolution is a form of computation that requires much on-board information to be built into it. (This information may be down to the precise selection of a very particular physical regime as embodied in our laws of physics - although this is a moot point). As Dembski says on the video, evolutionary algorithms, if they are to work, need to be carefully and correctly in programmed in advance (i.e. carefully and correctly selected). For example, on the subject of mutation as a mechanism that searches the fitness landscape Dembski quotes Stuart Kauffman who asks Where did the fitness landscapes come from?

My interpretation of Dembski is that he is not challenging evolution per se but is challenging any pretension that evolution can work in an information vacuum; mathematical necessity requires that evolution must start with the appropriately improbable preconditions (= high information conditions) and this entails the selection of a rare class of successful search algorithms. Dembski’s core thesis is irrefutable I believe. The information he talks of is to be found either in the laws of physics as we know them or some mechanism layered on top of this physics. (See my discussion here)

I think that Dembski has touched  a sensitive nerve because he has made it clear, as clear could be, that as far as observed cosmic space-time scales are concerned the universe has been set-up with inexplicable brute givens; that is, it has an irreducible load of non-trivial information. This conclusion cuts across any idea that life is an all but trivial logical outcome of informationaless conditions. In absolute terms then, evolution, even if it has occurred in the way the academic establishment would have it, doesn't explain the up-front burden of improbability that is our cosmos.  This is an uncomfortable conclusion begging many questions which have an impact our Weltanschauung. If one wants to explain the breathtakingly unique giveness of the cosmos, something “naturally” eternal has to be assumed. How one handles this Grand Logical Hiatus, whether via a given multiverse or a given intelligence, is the difference between atheists and theists. Dembski’s main academic heresy seems to be that he has used this conclusion to moot the idea of an a-priori intelligence as the source of this logical hiatus. But it is likely that even his undoubtedly correct core thesis that the cosmos and its life forms are far from being trivial logical truisms starts establishment hackles rising because they know what’s coming next!
***
But having said that all that I have to say (yet again) there is something profoundly unsatisfactory with the Intelligent Design community’s use of Dembski’s work.

At the beginning of his talk Dembski makes a very interesting point. He says that creation and design are two different things: Creation is about the ultimate source of physical ontology and design is about the way in which that ontology is configured. He goes onto say that you can have creation without design and design without creation. Dembski seems to be thinking about two apparently distinct logical possibilities:
a) Creation without design: Here a physical ontology is sourced in some eternal creative agent, but this ontology displays rather boring forms; either very simple high-order or high-disorder. Intuitively we would be unlikely to rate such a cosmos as displaying particularly clever or intelligent designs.  
b)  Design without creation: Here we imagine a cosmos that has always existed (that is, it is an uncreated physical ontology) but which nevertheless displays clever designs taken from a very narrow class of complex ordered structures such as we find in living things.
This looks compelling but I’m not quite sure I can go along with this distinction between creation and design. To my mind a cosmos that doesn't display division, separation and difference is unintelligible: For example, creating matter is to create a demarcation between matter and its space-time theatre; a binary sequence without any bits set - that is without difference - is effectively void. There is no substance without demarcations being made and it is very telling that the early verses in Genesis 1 are largely about the transformation of formlessness and emptiness through the making of separations and divisions. To create matter is to create distinction. To create distinctions is to configure. To configure is to design. Ergo, creation is design and design is creation.

But not all designs are equal: A particular configuration will entail a certain level of computational complexity and this will set a lower limit on the computational resources needed to generate it. Therefore as I understand it Dembski’s “Creation without design” is probably intended to cover the case where we have “simple” designs that set the computational complexity bar rather low, but which actually don''t reveal just what is the upper limit, if any, is on the computational resources available. As for “Design without creation”: Unless we are dealing with an extremely static status-quo where there is absolutely no change in difference and distinction I think it is all but logically impossible to separate design from creation, so I'm not sure if we are dealing with an intelligible concept here.

I'm suspicious of Dembski’s creation vs. design distinction and it is, I suggest, a manifestation of a potential problem: It is a short step from this dichotomy to a dichotomy that sets the substance of nature over and against the designer for whom nature’s substance is the medium on which he or she (usually “he”) works. Nature thus becomes a thing in “her” own right, albeit rather passively receiving the configurations imposed by the will of the male designer. But the irony here is that this dichotomy prompts questions over whether nature is quite so passive. In fact Dembski himself makes the point: He talks about nature and intelligence both being agents that shape matter into configurations. He tells us that nature and design are two different sources for the structuring of matter. He gives us the example of an acorn as compared with raw oak wood. The acorn has within itself the information to construct an oak tree whereas raw oak wood can’t turn itself into a ship; the latter configuration has to be imposed from without by an intelligence, and probably a male intelligence at that.

But if nature has at least a modicum of innate power to organize herself, is it “just” nature that has generated life? Regarding the efficacy of nature to create living configurations Dembski asks:

Is nature complete? Can it bring about the structures of life or does it need more information? E.g. can natural selection do it? Does nature have what it takes?

In the culture in which Dembski moves these questions are likely to be thought of as rhetorical, to be answered in the negative. For if the answer to these questions is “yes” that is very easily read as a case of: “Because nature did it that means God didn’t do it”. If nature, like the acorn, has been appropriately primed and has what it takes then this could be construed as rendering a male creative deity redundant! Thus Dembski is inadvertently helping to promote a dichotomy which, amongst theists, may well encourage a dim view to be taken of attempts to explain living structures in terms of the given cosmic physical regime. In this context it is perhaps no surprise that many North American Christians are vehemently anti-evolution:  For them God is a kind of virile homunculus engineer, an external designer who does things to passive nature much as the potter does to the clay.  But here’s the irony: This kind of deity is on a commensurate logical level to Mother Nature “herself” who, although in a masculine context is likely to be thought of as an inferior passive object on whom things are done, may in a more feminist context become a female goddess with powers of creation in her own right. The way is thus paved for the Nature did it vs. God did it dichotomy. (See also here). Much as I admire the work and undoubted courage of Dembski he’s connected himself with a line of thought here that I’m loath to follow
***
In order to express the otherwise incomprehensibility of the Divine it is a well-known theological trick to use “paradox”; that is, to keep in one’s head a cluster of different metaphors some of which may appear to be mutually inconsistent: For example, the paradox of God’s simultaneous eminence and immanence can be dealt with using mutually “inconsistent” metaphors. In the book Planet Narnia author Michael Ward discusses C. S. Lewis’ use of the Solar Disc as a metaphor for God’s eminence. According to Lewis this metaphor must be balanced against the metaphor of God as a quasi-tribal deity, in order to convey God's immanent nature. On page 119 of Ward’s book we read:

One of the dangers of solar theological imagery is that it tends toward a kind of docetism, the heretical view that Christ only appeared to be human, and Lewis naturally, as a self- consciously mainstream, orthodox writer, wanted to avoid giving a docetic presentation of Christ. In order to understand his thoughts on this matter it will be worth looking at what he says elsewhere about Akhenaten's Hymn to the Sun  (1400 B.C.).
The Solar monotheism of the Hymn to the Sun seems better, in one way, Lewis argues, than the primitive Judaism we find in the early books of the Old Testament, but it does not follow that 'Akhenatenism' would have been a better  first step in the history of divine revelation. Akhenaten was astonishingly advanced; he did not identify God with the Sun in a strictly heliolatrous way but understood the visible disc as a divine manifestation. This early Egyptian religion, 'a simple, enlightened, reasonable Monotheism,' looks much more like developed Christianity, from one perspective, than those first documents of Judaism in which Yahweh appears to be little more than a peculiar tribal deity. However, Lewis concludes:

“If Man is finally to know the bodiless, timeless, transcendent Ground of the whole universe not as a mere philosophical abstraction but as the Lord who, despite his transcendence, is "not far from anyone of us", as an utterly concrete Being (far more concrete than we) whom Man can fear, love, address, and "taste", he must begin far more humbly and far nearer home, with the local altar, the traditional feast .... It is possible that a certain sort of enlightenment can come too soon and too easily. At that early stage it may not be fruitful to typify God by anything so remote, so neutral, so international and (as it were) so inter-denominational, so featureless, as the solar disc. Since in the end we are to come to baptism and the Eucharist, to the stable at Bethlehem, the hill of Calvary, and the emptied rock-tomb, perhaps it is better to begin with circumcision, the Passover, the Ark, and the Temple. For  “the highest does not stand without the lowest". Does not stand, does not stay; rises, rather, and expands, and finally loses itself in endless space. For the entrance is low: we must stoop till we are no taller than children in order to get in.”

It is Lewis's intention in The Voyage of the 'Dawn Treader’ to typify the divine figure by means of the Solar disc, to emphasize his transcendence and universality. Aslan here is very different from the furry beast who romps and battles cheek by jowl with the children in the first two nooks. He floats in and out of this story in intense moments of prayer, reproof, spiritual illumination and mystical ecstacy; he has a rarefied exalted existence, which is constantly at risk of being lost in endless space….
Akhenaten Worshipping the One and Only God. Trouble is, he eventually set himself up as the One and Only Son of God! (How often have we seen that?)

The transcendent vision of God conveyed by Lewis’s Solar metaphor has ultimately been grounded in the human personality of Christ who is portrayed in Colossians 1:15 as the homunculus craftsman of creation:

For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. (Col 1:15)

But the Bible itself, in a similar move to Lewis, raids pagan literature to offset the potentially idolatrous literalism of the homunculus vision of God. In his visit to the pagan context of the Areopagus St. Paul sets the scene by a respectful appeal to a common ground theology (Acts 17:24-25):

The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by human hands. 25 And he is not served by human hands, as if he needed anything. Rather, he himself gives everyone life and breath and everything else.

….which contains an idea very close to the pagan Euripides who said (See also Acts 7:48):

“What house built by craftsmen could enclose the form divine within enfolding walls”

St. Paul goes on to say: (Acts 17:26-28):

 26 From one man he made all the nations, that they should inhabit the whole earth; and he marked out their appointed times in history and the boundaries of their lands. 27 God did this so that they would seek him and perhaps reach out for him and find him, though he is not far from any one of us. 28 ‘For in him we live and move and have our being.’ As some of your own poets have said, ‘We are his offspring.

Verse 28 here contains a quote taken from Greek literature. These words were put into the mouth of the semi-mythical Epimenides of Crete who legend said erected anonymous altars around Athens. (A legend which Paul also alludes to in his address at the Areopagus – see Acts 17:23).

They fashioned a tomb for Thee O holy and high One
The Cretans always liars, evil beasts, idle bellies,
But thou art not dead; for ever thou art risen and alive,
For in thee we live and move and have our being,
For we are indeed his offspring.
(From the poem on Phenomena by Aratus of Cilicia). (See also Titus 1:12)

Paul connects to his knowledgeable Greek audience by allusions to pagan literature and by endorsing common-ground notions of God. But in doing this St. Paul balances the metaphor of God as a masculine homunculus imposing his will on nature from without against a more feminine nurturing metaphor of God as the womb-like receptacle that sustains our very existence and from whom we are the offspring. St. Paul, like C. S. Lewis, respected pagan views of God.

The masculine homunculus metaphor for God, if used exclusively, is in danger of causing a bifurcation that delivers up a second competing God, namely Mother Nature, the “inferior” co-rival of God himself. In contrast the Biblico-Pagan picture of St. Paul harmonises the masculine and the feminine. 

It is ironic, however, that even in today’s sectarian slanting evangelicalism we can find the “pagan” Solar Disk being celebrated as a metaphor: How many times have I seen the laser projector, which is so central to Christian worship today, throwing up an image of charismatic songs set against a backdrop of a scene flooded with Sun light or whose focus is the Solar Disk?

The First Conspiracy Theory: The Kennedy Assassination.


The Zapruda footage of the assassination

I don’t really think the Kennedy assassination was the subject of the first conspiracy theory but in 1963 it felt like that to me. I was 11 when Kennedy was killed, old enough to remember where I was when I first heard the news one Friday evening, and old enough to be aware of the growth of conspiracy theories over the days and months following the assassination. My other memory was of a disquieting sense of a cowboy style “gun law” ruling in the US; the shooting of suspect Lee Harvey Oswald by Jack Ruby a few days later occurred in spite of the presence of custodians of the law.

I have recently turned to the Kennedy assassination because of my developing interest in conspiracy theory and with the hope that perhaps it will throw some light on the question of why conspiracy theories are so popular. In fact according one of the videos I watched 90% of the stuff out there on the Kennedy assassination is conspiracy oriented.

One human trait that is likely to favour conspiracy theory is the cognitive ability to join the dots of evidence using highly imaginative narratives. I have touched on this subject early on in this blog; see here and here. All our perceptions involve the activity of embedding data samples into imaginative theoretical narratives (see the side bar on this blog). In fact looking back this blog has been about nothing but the epistemic questions revolving around the human activity of embedding experiential protocols into complex story telling narratives. These narratives constitute our theoretical interpretations of what we observe.

The more complex is the ontology behind our observations the less trivial is the epistemic exercise of trying to arrive at “true” theoretical interpretations of the accepted data samples. The activity of theorizing, even when formalized as per the scientific establishment, does not easily yield up unique theoretical solutions; the problem of multiple possible theoretical solutions is especially apparent in the humanities where complex ontologies like history and evolutionary psychology are grappled with. The Kennedy assassination is a case in point. Historical interpretation very often throws up undecidability issues like this.

In order to get a handle on the Kennedy assassination I recently watched the Utube videos here and here (and dipped into some others).  The first one is by reporter Gavin Esler. He takes the view that Lee Harvey Oswald was a lone-wolf gunman who shot Kennedy for idiosyncratic reasons. The second video by Robert J Groden seeks to show that at least two gunman must have been involved. Groden’s documentary is restrained compared to the extravagant speculations of some conspiracy theorists and he doesn’t stray far from the basic evidential protocols. Nevertheless one can detect a conspiracy undercurrent in Groden’s ideas; for example he talks about the authorities fitting the facts of the case to “the predetermined myth of a lone gunman”. Behind Groden’s otherwise sober production one gets glimpses of shadowy nefarious intelligences lurking in the imagination of this producer.

(Note: The Esler video linked to above is now no longer available on YouTube)

Both documentaries take cognizance of evidences that the other fails to do justice to. But perhaps this can be excused: The Kennedy assassination created a mountain of evidence. The Warren commission alone generated thousands of pages of testimony and data. Can anyone show that their theory is a good fit to all the available protocols?


Virtual reality view from the Oswald "sniper's nest": Note that the tree under the window doesn't obscure the view of Kennedy's car.

The Esler documentary focuses on the character profile of Oswald, Jack Ruby and the single bullet theory. The single bullet theory is neatly dealt with using a virtual reality construction. This shows how the high velocity Mannlicher Carcano bullet from the “snipers nest” in the Texas book depositary could trace a straight path through the soft tissues of both Kennedy and Governor Connolly, finally being deflected by the latter’s wrist bone. Oswald’s misfit character profile is consistent with the idea of a lone gunman; in fact the documentary tells us that Oswald had already attempted to assassinate a public figure – General Edwin Walker – although this attempt had failed.


A general view of Dealey Plaza where the assassination took place.

The Groden documentary gives no time to Oswald’s character and repeats the claim that an impossible zig-zagging bullet is required for the single bullet theory. Groden focuses on Kennedy’s wounds and the autopsy photographs and reveals a genuine problem: Some of the Warren commission photograph’s of Kennedy’s wounds are inconsistent with the memories and accounts of the doctors who attempted to resuscitate Kennedy. With this problem in mind the documentary goes on to consider photographic evidence that there was at least a second gunman on the famous grassy knoll. There were also witnesses to this effect. However, the rather grainy Utube video showing shadowy smudges on the knoll doesn’t make this evidence very compelling. A weakness in the epistemic method of conspiracy theory is shown up here: The gunman on the grassy knoll works if one sets out by assuming he is there; in fact the grassy knoll gunman leaps out of the smudges only if one is first convinced this assassin is there! 


The black dog man; see left most red arrow.

Although it looks to me as if Groden has exposed a valid problem with the Warren commission’s photographs I’m not very convinced of his “black dog man” assassin. The Zapruda footage showing the fateful head shot does give the first impression of a bullet coming from Kennedy’s front and right. But looking at the position of the “black dog man” relative to Kennedy when he received the head shot, it appears to me that this man is too far to the right side of Kennedy’s head to account for that shot. A bullet from the black dog man would have struck the right side of Kennedy’s head, also blowing out the left hand side of his skull; but the left side of his skull was undamaged.


Click to enlarge: Any bullet from the black dog man at the top of the grassy knoll steps would have hit the side of Kennedy's head. This is a map by a conspiracy theorist who believes that a tree obstructed the view of Kennedy from the "Oswald window".

When Kennedy received the shot to his head he was already suffering from gunshot wounds and had slumped with his head down. This meant that the back of his head moved uppermost. Therefore a bullet hitting  his skull, either from the  rearward or forward directions, would have had the effect of slicing off the top and side of the skull toward the back of his head and this is what Groden’s medical witnesses testify to having seen. But if the shot came from the forward direction we are then left with the problem of identifying just where this forward gunman had his nest. That leaves us with the alternative of a shot coming from the rearward direction, toward the school book depository.


A tragic picture I know, but this autopsy photo is what I'd expect to see. 

But whatever! Seeking a solution to the assassination is not why I am here. Much more pertinent to my interests is the development of the conspiracy theories surrounding the case and just what “itch they scratch”. In this connection I was interested in Esler’s views on the 1991 film “JFK” by Oliver Stone. According to Esler Stone took huge liberties with his artistic license. The corrupt lawyer Jim Garrison was, as Esler puts it, “resurrected as an American hero” by Stone. The film suggests that the responsibility for the assassination went right to the highest levels of government. Esler says that the American public took the film to heart; this, it seems, was the stuff they were very ready to hear and very ready to accept, but why? Why are they so much less likely to believe in the “lone nut” theory? As one of Esla’s commentators put it: They couldn’t accept that someone as inconsequential as Oswald could kill someone as consequential as Kennedy. If Oswald was the “lone nut” who killed Kennedy that would mean the whole thing hinges on a random happenstance: Oswald was the man with the wrong character and with the wrong background who just happened to be in the wrong place at the wrong time. A high powered rifle gives a misfit like Oswald an extremely powerful way of expressing his frustrations. Is America really prepared to accept that its gun-freedom hands such power of expression to random "nutcases"? The upshot is that it's tough luck on Kennedy and the country he was running! It is a difficult lesson to accept that life, national life even, could be so vulnerable to a chance event. Who do you get angry with when “chance” is the culprit? It is much more cathartic to blame the evil deed on culpable and high ranking persons, especially if it is part of your national culture to be suspicious of the motives of government; after all the US was formed from dissident Europeans who wanted to get away from their autocratic and interfering governments!

A proper analysis of the Kennedy assassination evidence could consume a life’s time’s work. All I have done above is given my first parse impressions. But in spite of that I sense in myself a propensity to favour the theory that Oswald was the “lone nut” who troubled the world of the high and mighty in 1963. But why do I personally have a predilection toward the Oswald theory rather than the popular conspiracy theories even though I haven’t done justice to the mountain of evidence? I think this is very much a function of personality; some of us are more likely to see the world through conspiracy theory than are others. In my case I think I'm more predisposed to believe that reality works in the Oswald way rather than the conspiracy way; that is, I'm more likely to see the world in terms of unpredictable impersonal patterns rather than instinctively personify them as the grand-slam plan of sentience working behind the scenes and pulling all the strings. If then this is my personality bent it is no surprise that one of the first private academic projects I busied myself with was that of arriving at an understanding random patterns. Another problem I have with conspiracy theory is that I have a hard time accepting the conspiracy theorists claim that human beings are capable of engineering highly sophisticated plots involving many players, plots that display an exceptional level of (malign) intelligence  and organization, and yet at the same time exceptional levels of stupidity. e.g. Who would use a multi-man man assassination squad amongst crowds of witnesses, not to mention the expert witness of doctors, with the intention of passing it off as the work of a lone gunman? Or, who would invent a lone gunman’s snipers nest with a target that conspiracy theorists claim was obscured by a tree? With their highly elaborate preconceived plots and yet which miss the obvious, conspiracy theories often look suspiciously like badly contrived fiction. The complex ontology of our world makes for an all but unpredictable world and therefore very likely to frustrate such plots. Consequently, when it comes to plotting human beings tend to work in an after-the-fact opportunistic way, improvising as they go along. In fact in a chaotic world responding to feedback and re-routing one’s “plan” is the chief strength of human intelligence. If there are anomalies in the Kennedy assassination evidence you can bet it’s because someone has done a faux pas somewhere and then had to do the job of cleaning up afterwards.

***
The exceptional talent human beings have for theorizing has both an upside and a downside. This talent requires prodigious amounts of innate imagination. Therefore I suspect that the ability to turn patterns into “theory” uses cognitive abilities that are “hard wired” into our brains. In particular the whole domain of reading people, of which the language instinct is an important part, is likely to use a-priori mental templates for interpreting human situations. For example facial recognition is based on an instinctual template for reading face-like patterns; it is therefore no surprise that I find myself involuntarily “recognizing” facial patterns in just about any collection of random splodges! However, the downside of this a-priori mental processing, as the example of face recognition shows, is that it can result in false positives – we easily see things that aren't there. My conjecture therefore is that because so much of our brain power is devoted to social processing, this comes with the risk of reading sentience, intention and purpose into situations that don’t have it. One thing worth noting here: Sentience is never equivalent to the thing we are observing. In an absolute sense sentience, if it is present, is always perceived to be behind the sensational interface, just as we believe reality in general to be something “behind” our sense-experience of it. Our instinct therefore is to perceive sentience as a kind of puppet master pulling the strings behind our perceptive interface. This cognitive ability to extrapolate beyond the interface so often generates profound insights, but it has the downside of coming with the risk of seeing the world through fanciful narratives.

The ease with which our imagination pictures sentience to be at work behind the scenes is not just a passive activity: I suspect we may pro-actively go looking for sentience, because we are inclined to feel that something is not satisfactorily explained until we find purpose behind events and purpose only has meaning in the context of sentience. In this connection I'm reminded of the observations Dr. Jim Harries is returning from his consciously minimally intrusive missionary presence in African rural society. The African rural mind is apt to interpret changes in the status-quo as being initiated by some version of sentience working through magical influences. In particular bad things that happen may well be read as the expression of either displeased ancestors or living antagonists practising witchcraft against people. Now, in the West although there is a lot less belief in magical influences, there is still, may I suggest, a very natural propensity to read ill-will behind bad events: As one studies one conspiracy theory after another one finds the same pattern emerging; a perception of ill-fortune as the unseen machinations of ill-will. Moreover, conspiracy theory allows one to multiply any number of shadowy players and entities in one’s imagination and these “adjustable variables” can be used to retrospectively fit any number of data anomalies to a pre-conceived belief in conspiracy. The attraction of conspiracy theory, therefore, is that it opens up the possibility of unify a wealth of disconnected data into a grand-narrative involving some ill-will pulling all the strings. In the West, of course, the mechanisms by which this ill-will expresses itself is unlikely to be thought of as magic, but nevertheless I'm coming to the conclusion that Western conspiracy theories have parallels with African witchcraft and magic. To many the Kennedy assassination was such a horrific affront to society that it is only satisfyingly explicable in terms of the Western equivalent of black magic’; that is a conspiracy. People find it easier to make social sense of the assassination as an outcome of evil intention. This resort to a microcosm of evil purpose probably satisfies the human psyche as an explanatory narrative much more deeply that an appeal to random patterns. As one of Esler’s guests put it Conspiracy gives purpose and meaning to tragedy rather than a twist of fate.

The maintenance of a balance between our delirious creativity and our destructive critical faculties is a difficult one to keep. Mental problem solving is always a tension between the creativity of searching & finding and the criticism of rejecting & selecting. We don’t always get that tension right.

End Notes:

1. As it just so happens 2013 is the fiftieth anniversary of JFK assassination. This is not due to planning on my part!.

2. At some stage I need to add a further note  here to explain how I relate theism to the above material

3. "Conspiracy theory", when it is raised to the level of a all-embracing grand-world view, needs to be distinguished from plausible conspiracies: For example the idea that Kennedy's death was orchestrated by an organised crime figure is at least arguable and isn't what I have in mind when I think "Conspiracy theory" - the latter is way of looking at the whole world.

The Bizarre Case of Bob Lazar.


The above YouTubes are videos of a couple of Bob Lazar interviews. Bob Lazar is the man who claims to have worked as a reverse engineer on an alien flying saucer at Area 51/S4. Two scientific skeptics, David L Morgan and Stanton Friedman, have debunked both Lazar’s grasp of science and his claimed CV (See here on Lazar’s Wiki page). For me another indictment against Lazar is Lazar’s treatment of American Anti-gravity aficionado Tim Ventura .

Be that as it may, I think most people would nevertheless agree that superficially at least Lazar is a good story teller. In the interview he appears to be relaxed and fluent. It looks to me as if Lazar has his story well-rehearsed; he gives the impression of not being fazed by any of the questions and is well prepared for them. If it is a hoax he must have spent hours running over it in his fertile imagination - in fact, built up his own mental virtual world that lies in wait for likely questions. As he answers the interviewers questions he doesn't falter and knows what he is going to say; his story includes interesting touches of observed detail that give it the authenticity of plausibility, as is the wont of all good fiction writers.  However, when it came to some of the technical details it has the touch and feel of a scifi cut-away diagram; a little bit of general annotating scientific patter here and there but no nuts and bolts. Lazar also has the skill of not over embroidering his story; he adroitly uses the device of a limited security clearance to avoid the danger of having to concoct potentially implausible scenarios about things we would love to know, such as how the area 51 people came by this alien vehicle. 

But as in the case of David Ike the Bob Lazar story reveals something about our society and it holds a moral. In fact towards the end of the first video Lazar himself eloquently draws out the lesson: Secrecy, over-security and closed authoritarian politics can stifle scientific research. Science flourishes best when both the debates and the files are open and available to a large community of scientists. An environment of shared information, especially information pertinent to our weltanschauung, gives less of a foothold for the suspicions, antagonisms, and the fanciful imaginings of the disaffected and alienated. Schismogenesis is caused by a regenerative circuit between two sides and is, to my mind, yet again implicated in an example of societal polarisation.  Lazar himself  helps that polarisation along when he says that government is not interested in protecting its citizens but is out for itself. Growing mutual distrust between the governors and the governed is the very reason why a story like Lazar's can take a hold in Western society. This is the chief lesson the bizarre Lazar affair teaches us.

Lies, Lies Damnable Lies … and Conspiracy Theory!

In a blog-post dated January 14th and entitled “Princeton student lies about the creation museum” Ken Ham reveals something of his fundamentalist habits of mind. A Princeton Physics student named Tyler Simko criticizes the creation museum in his blog and in response Ham launches into the all too typical fundamentalist revilement about “lies”. Viz:

….full of outright lies….outrageous claims…another lie….. egregious lie….. intentionally misrepresented…

Finally Ham, who was probably foaming at the mouth after that little lot, goes for nuclear button and deploys the ultimate censure; namely, that to be at odds with Ken Ham entails being at odds with God and therefore in danger of eternal judgement.

Simko’s flagrant lies make me want to pity him for the account he’ll have to give one day for his attempts to lead others astray and undermine Ken’s God’s Word.

Having an ongoing interest in the study of religious sects and cults I am very familiar with this knee jerk use of the word “lie”: A Jehovah’s Witness once told me I was a “lover of lies” and this reformo-charismatic fundamentalist  accused me of propagating a lie when I told him he was part of a religious sect.

To be fair Simko refers to the lies at the creation museum, but then, unlike Ham’s attack, Simko’s isn’t a personal attack; instead he attacks a culture rather than a person. In his reply to Ham Simko gives fair reason why he stands by all that he has said (apart from one retraction he has to make down to factual error). This is not to say I agree with Simko’s line of thinking, but his points are at least arguable and genuine; except to the perversely paranoiac they are clearly not intended untruths (=lies) as Ham tries to make out.

The final irony is that Ham asks the following:

I wonder if the young man will be honest enough to apologize to his readers and correct his false statements:

As far as I can see Simko has nothing to apologize for. If anything it is Ken Ham who should apologize for his attempted assassination of this student’s character using some very familiar (to me, at least) religious abuse. Fortunately Simko will have plenty of support from his science community and is therefore well out of reach of this kind of moral duress. Unfortunately that is not the same for many for whom fundamentalist sectarianism is a thoroughly intimidating cultural ambiance. As I have advised before: If you are attracted to God and faith, please avoid fundamentalism – as a culture it is well tuned to applying moral pressures and this can end in much grief. Above all, in the final analysis, it undermines the faith. As even Simko observes:
.
Additionally, I suggest to Mr. Ham that he direct more of a focus towards spreading Jesus’s fundamental messages of love, tolerance and “turning the other cheek,” as messages that I have received from many of his supporters have been anything but respectful.

Sectarian religions have the resources to apply some very strong emotional pressures to believers (See also here). Finally I would like to take this opportunity to once again remark that Ham’s fundamentalist habits of mind provide fertile ground for conspiracy theory (See here). The fundamentalist finds himself disconnected from the world beyond the narrow confines of his sect, a world that his culture trains him to treat with deep suspicion. Fundamentalists are likely to feel that if you are not with them then you must be against them and if you are against them you are against God, thus in effect committing the unforgivable sin. In particular, if you criticise them that is read as sure fire proof you are in thrall to Satan the father of lies and therefore depraved. No matter how one might reason the fundamentalist reads it as the chicanery and artifice of a black heart worthy of the kind of moral abuse we see Ken Ham handing out. It is no surprise that this jaundiced disaffected outlook on the extra-sectarian world easily crystallises into some expression of conspiracy theory.

Generalised Fundamentalism.



“Human Fundamentalism is an explosion of your alter ego” says the blurb; but tribalism is also likely to be factor.

PZ Myers has been recently bad-mouthing “accomodationist” atheists Peter Higgs (of Higgs Boson fame) and Peter Kloor both of whom appear to take a complaisant stance toward theists (at least theists of the more liberal variety). In fact Kloor and Higgs use the term “fundamentalist” of the kind of culture that PZ Myers represents.  This, need I say, annoys PZ Myers no end.
 
In spite of my own working theism I would not want to claim that the evidence relevant to God’s existence is overwhelmingly compelling: We have lots of anecdotes, feelings, intuitions, personal revelations, and some historical documents of debatable status, although we do have some very interesting philosophical pointers. But all this evidence is insufficient, in my opinion, to condemn fair minded people like Higgs and Kloor to an eternity of torture, as some fundamentalists would have it. Moreover, the mindless brute sectarianism of much fundamentalism is evidence that weighs heavily against theism and registers with me as mitigating circumstances as far as atheists are concerned. 

One can hardly blame a reasonable atheist/agnostic for being noncommittal about anything other than the products of the hard sciences: Physics, Chemistry and to a certain extent biology have given us a picture of realities that are highly coherent and rational, objects that one can return to at will and find consistency and persistency. In comparison evolutionary psychology, history, sociology and the like have a complexity of subject matter that would be epistemically intractable if we tried to treat them with the same formal methods of the hard sciences. It gets even worse with the paranormal: Ghosts, cryptozoology, aliens, and religion are largely based on observational erratics and subjective feelings. One can hardly blame people for washing their hands of the whole business of the paranormal when its material is so epistemically unfriendly. Moreover, many religions make good their irregular evidential status with liberal dollops of Gnosticism, fideism, legalism, godbotting and above all the fear of the unknown; it is no surprise that much fundamentalist religion majors on spiritual threats about the grave consequences of incurring divine displeasure.

But the inherent difficulties of paranormal material are also its own claim to mitigating circumstances.  Theism is a product of an informal world view synthesis and the enunciation of some very high level objects and concepts. These objects and concepts are hardly the stuff of spring extending and test tube precipitating science . When it comes to this kind of world view synthesis unequivocal truth statements are hard to come by and the formal epistemology of the physical sciences which is at its the best when handling the elemental breaks down. In fact this break down starts to happen in formal science itself: On PZ Myers’ own admission science is making very heavy weather of evolutionary psychology and not surprisingly in my view; mental phenomena are highly complex implying a concomitantly highly convoluted natural history.  When it comes to an object like natural history, which is both very complex and necessarily untestable at will, we have to fall back, to a large measure, on “best fit science”; that is the kind of retrospective analysis that employs lots of imagination as attempts are made to fit the received data into some preconceived theoretical narrative. I see nothing wrong with this kind of activity given that it is imposed upon us by circumstances beyond our control and as long as it is carried out with self-awareness, tentativeness and above all with epistemic humility. But a call to epistemic humility is unlikely to be listened to: At the ontological high end people are playing for high stakes and human nature ensures that the difficulties arriving at unequivocal conclusions are made up for by an accompanying epistemic arrogance. A shouting match. is inevitable, but if we are to cling to truly democratic traditions then we must accept that in democratic societies the great parliament of ideas  is going to be like other parliaments I’m familiar with; namely, a kind of controlled row.

PZ Myers doesn’t like being compared with religious fundamentalists. Just how far he qualifies for the label “Science fundamentalist” depends on how strict he is with his epistemological Methodism: The formalties of spring extending and test tube precipitating science are guarded so jealously by some that they declare anyone transcending them to be anti-science heretics. It is no surprise, then, that science fundamentalists get uptight about evolutionary psychologists: The complexity and epistemic inaccessibility with which evolutionary psychologists have  to work gives them little option but to fall back on less formal and reliable methods; that’s OK with me as long as they proceed with epistemic humility.

Religious fundies, like science fundies, seek a formal epistemology that excludes all others on pain of charges of “heresy”. The epistemology of the religious fundamentalists revolves around treating scripture in a highly notational rather than connotational way : That is, they are quite sure they can readout very literal lessons from scripture using sure-fire mechanical rules; “Godbotting”, is the term. Both science and religious fundamentalists seek an exclusive and overriding authoritative epistemological Methodism that gives them a base from which they can scream down hell and damnation on all who transcend their methods. They are, as a rule, very hot on the idea of accessing and telling people “The Truth”, but they are unwilling to admit that at all but the lowest of levels, claims to being the mouth piece of “The Truth” must be treated with the utmost caution. For fundamentalists of all kinds there arises a conflict between their version of “science” and other world views because they don’t take seriously and are uncomfortable with the epistemic difficulties found at the high end. The telling trait of all fundamentalism is its insecurity with ambiguity, especially the ambiguity surrounding answers to the big questions of life; it consequently seeks and often thinks it has found a sure fire epistemic method. The outcome of that is an all too common epistemic arrogance.

12/02/13: Note On Evolutionary Psychology:  See the following two links for the opinion of anti-theists Larry Moran and  PZ Myers on the subject of evolutionary psychology:

http://freethoughtblogs.com/pharyngula/2013/02/11/kate-clancy-tackles-evolutionary-psychology/
They pretty much give a blanket rubbishing to all academic efforts in this field. What they don't seem to understand is that one can't port the same highly formal standards used by spring extending and test tube precipitating science to the study of people. It's like a physicist or a mathematician telling an historian how to do his job. When it comes to the humanities we come to terms with the lack of epistemic rigour imposed by complex inaccessible ontologies by giving formal place to controversy, non-consensus and the argument of parliament - the very things that are anathema to the instinctual epistemic arrogance of the  fundamentalists.

Paul Nelson, Computer Simulations and .... Gravity.

Evolutionists and Anti-Evolutionists continue to slug it out.

This video featuring a presentation by Homunculus IDer Paul Nelson has stirred up a response from the evolutionary establishment. The relevant links are:

Paul Nelson is not just a Homunculus IDer; he is also a Young Earth Creationist. But there are YECs and YECs; As far as I can tell  Nelson is not one of the hardened “heretic burning” religionists exemplified by the likes of Ken Ham and his ex-business partner John MacKay (In fact MacKay is probably lunatic fringe). Nelson, like most of those in the Humunculus ID community (or “HIDs”), seems to be a reasonable and intelligent man; somebody, in fact, that any other reasonable person could do business with even in the face of mutual disagreement; Nelson probably has a YEC background, but he is nevertheless prepared to work with non-YEC Christians.

The argument that Nelson has triggered seems be about the relative importance of natural selection over and against other mechanisms that may drive evolution natural history. I’m not going to comment on this matter because firstly I'm not a biologist and secondly it’s one of those grey areas about degree: Viz: Just how important does the evolutionary establishment claim natural selection to be as an agent of change? Have they overestimated it or underestimated it? Contrariwise just how unimportant is Nelson claiming natural selection to be?  Is he overestimating or underestimating its unimportance? The outcome of this kind of dispute is that it has a tendency to degenerate into a “he said, you said” farce.

Although Nelson is the kind of guy I can respect and moreover I think the evolutionary establishment needs the well-motivated and intelligent criticism (albeit largely negative and destructive) we get from people like Nelson, I still feel that there is something highly unsatisfactory about the underlying motivations and concepts behind Nelson’s attack on evolution. My sense of unease is bound up with the pervasive "God Intelligence did it vs. Natural Causes did it"  paradigm with which Nelson frames the issue. This framing is evidenced by the implicit reference Nelson makes to William Dembski’s explanatory filter.

The explanatory filter is an epistemic method whereby one works in sequence through the possible explanations of an observed configuration starting with "natural causes" founded in law and disorder. (i.e. what the HID community inappropriately refer to as “chance and necessity”). If law and disorder fail to explain the configuration this leaves us with, by default, intelligent causes. Certainly, within the confines of the cosmos the ideas behind the filter are robust:  Law, disorder and intelligence (perhaps even alien intelligence) cover all possible agents of change that we can conceive. But though this may be the case, in a theistic context the filter proves to be problematical. To see this let’s imagine for the sake of argument that establishment evolutionists “prove” their case beyond reasonable doubt. Using the explanatory filter it would then appear that the game is up for theism:  The explanation that “Intelligence (=God) did it” has been displaced in favour of “Natural causes did it”. To salvage their position, however, the HIDs will then tell us that our universe is fine tuned to favour the generation of living configurations and that this fine tuning has the effect of triggering the explanatory filter's default explanation of intelligent agency. But the trouble is that the explanatory filter cuts both ways: It now suggests that if one can find a law and disorder explanation for the fine tuning of the universe, then there is no need to posit divine intelligent “first causes”. But it turns out that law and disorder explanations have their own problems: To cut a long story short we find that attempts to arrive at a complete law and disorder explanation has the potential to lead to a classic turtles all the way down regress: Law and disorder explanations always leave a residue of brute facts that either have to be simply accepted as axiomatic, or as a trigger for another level of explanation accounting for why these particular givens have been specially selected for and not others. The inevitable problem here is acknowledged by Max Tegmark who gets round the conundrum of special selection with his mathematical universe, a weird and disturbing place where every conceivable mathematical object has been equally reified.

Naturally enough the HIDs want to stop this regression process from the outset by unequivocally showing that law and disorder are incapable of explaining living configurations; for if the situation is allowed to get into a multiverse regress it becomes too abstruse for a decisive victory to be claimed by either side. The consequence is that the HIDs have put down a very high stake in favour of intelligence in the “God Intelligence did it vs. evolution did it dichotomy, a dichotomy of thought encouraged by Dembki’s explanatory filter. Nelson and many other HIDs therefore have a great vested interest in discrediting evolutionary theory. They follow a negative approach which by a process of destructive elimination is intended to leave us with the default of God intelligence as the “cause” of life.  In the video I have linked to Nelson refers disparagingly to the wall surrounding law and disorder explanations, a wall which implicitly excludes thoughts of intelligent “causes”. Therefore for Nelson it’s a stark choice between naturalism and supernaturalism intelligence. William Lane Craig’s support of the Kalam cosmological argument comes out of the same stable: He is adverse to multiverse scenarios because they ostensibly attack his “divine first cause” argument by muddying the waters with a potential "natural causes" regress. Craig, like Nelson, thinks in terms of causes rather than patterns amenable to mathematial description. This causation concept of explanation readily leads to a way of thinking that views God’s involvement as the diametrically opposed alternative explanation to natural causes. (See endnote 3)

Nelson and Craig have categories of thinking which inclines them to put “natural causes” and “divine causes” on the same logical level thus pathing the way for God and nature to be seen as competing agents of explanation. This fails to do justice to the nature of intelligence, especially divine intelligence. I can best express this with a computing metaphor: It is possible to simulate a computer within a higher level host computer. In fact a simulated computer could be just one of many agents that act within the simulacrum of a virtual world rendered by the host computer. In such a simulacrum the simulated computer would stand alongside and have the same logical level as other categories of causation in the simulacrum. But in this scenario computation is actually the outer embracing context and therefore it is of higher logical level than the particular law and disorder regime rendered within the simulacrum.  Intelligence and computation are closely related; both have a dynamic that involves searching, rejecting and selecting, along with the interim production of partial results. So, if intelligence is anything like computation it too is likely to have an abstract, general all-embracing superset definition. It is conceivable, therefore, that our universe is running on (or "in") an intelligence/sentience rather than a "nuts and bolts" computer.  If a host intelligence is the embracing substrate on which our world is being rendered this means that the schism between intelligence and naturalism prompted by Dembki’s explanatory filter is very inappropriate; this schism is a result of placing law & disorder on the same logical level as intelligence. 
 
Like other HIDs Nelson defines evolution as a dumb process (See here where we find Richard Johns doing a similar thing). But even if the mechanisms of evolution are as the academic establishment would have it, then it is very wrong to call evolution dumb: If evolution is to work its efficacy is likely to be very dependent on the selection of the right physical regime. If evolution works then the aim at a distant functional target (As Nelson puts it) has taken place in the selection of the right physical regime. Intelligence has already been built into the process of evolution and evolution is, in fact, intelligence at work.

But having said that this is not to say that evolutionary theory is sown up.  I’m the first to concede that we may be far from understanding the full set of mechanisms driving evolution. Evolution is a present tense continuous process, but unlike the objects of spring extending and test tube precipitating science the changes it generates are smeared over very large tracts of time. We are like ants crawling over the surface of a huge evolutionary tree (or bush!) trying to reconstruct a highly complex shape.  Our attempts at reconstruction should be admixtured with a certain amount of epistemic humility. But in the polarized and passionate North American political and religious environment the sad fact is that a shift toward epistemic humility is not going to happen.

Nick Bostrom’s computer simulation theory is relevant to this post. A flurry of links have appeared on the subject of a simulated universe. See:

I touched on the subject of a simulated cosmos here (with tongue in cheek!):

David Deutsch is good on the subject of Physics and Computation: He is developing a theory of physics that only makes recourse to the constraints on computation, an indication of the superset generality of computation. See here:
Endnotes
1) A computer needs to be instantiated by some kind of law and disorder regime, but because computation is a concept that is independent of the exact computing model instantiating it, then the precise nature of the instantiating regime of the host computer is not easily accessible to the inner simulacrum. This is because the computer model reifying the host computer is one amongst many possible models and the formal structure of the simulacrum is insensitive to that model. If, like computation, intelligence is a general abstraction this will mean that the nature of the medium reifying the host intelligence is likely to be all but unrecoverable from the inner simulacrum.

2) As with computation one might expect sentience to be reified on some kind of law and disorder medium. The question then arises: Which comes first: Law and disorder or intelligence?  Law and disorder regimes are too simple in structure to be self-explaining – they cannot have the property of aseity.  Since complexity has no apparent upper limit aseity may be hidden in the upper reaches of sentient complexity. It may be wrong  to think in terms of law & disorder causing intelligence, or, vice versa, intelligence causing law and disorder. Law & disorder and sentience  may not proceed one out of the other but of necessity go hand in hand: Viz: Sentience will explain itself in law and disorder terms, but for the elementals of law and disorder to have positivist/experimental meaning the a-priori complexities of conscious cognition are required to host these elementals and give them context.

3) Patterns vs. Causes: In the final analysis our scientific epistemology only ever reveals the pattern of things; that is, science provides us with what is essentially a means of describing the cosmic state of affairs. In fact we find that many of the patterns the cosmos presents us with are amenable to description using algorithms (what I refer to as “law”) and statistics (what refer to as “disorder”) - hence my use of the phrase “law and disorder”. The concept of “cause” is really a special case term that is usually applied when a pattern can be described with a “deterministic” algorithm that computes the pattern in relatively short time. (Although one could say that a quantum event has been “caused” by randomness - i.e. a disordered pattern - this usage would probably be considered as rather strained).  “Causation”, in my view, is very much a subset category within more general categories of pattern description. It is with the foregoing in mind that I am uneasy about William Lane Craig’s and the HID community’s stress on the causal role of God in creation. This view of God favours the assignment of God to the wrong logical category; that is, as an ancillary homunculus source of causation rather than as an embracing substrate.
