Blue Brain, BBC and Global Minds: gullibility and hyperbole.

 
In both GB and Europe the high-blown claims for what we may learn from computer neo-cortex simulators continue to be propagated by the web entertainment journalists at BBC.  Here is a quote from web BBC:
The scientists say the project could lead, for example, to new ideas on how psychiatric disorders develop - illnesses such as autism, schizophrenia, and depression.
Here are my last few tweets at this point:

rshifflet G. Robert Shiplett
Brain simulator advocates do not propose to explain why some people ignore principled objections to their research proposals or faith or

rshifflet G. Robert Shiplett
Why not claim that your neo-cortex simulator may explain _________ (here you fill in the blank with any apparent dichotomy in behaviour.)

rshifflet G. Robert Shiplett
computer brain simulator builders claim that all they need is more money; theorists of AOP, stateful Traits, co-routines needed more time...

rshifflet G. Robert Shiplett
computer neo-cortex simulators suggest may explain schizophrenia - but why not explain 'tendency to exaggerate' or 'obsessed with computer'?

But before I stop mocking hyperbole in CS at unb.ca let me ask this: why is neither project working with the Vienna Freud society?  If fuzzy neural nets are to learn to "emulate mind" from Freudian fanatics, why would not at least one of these projects have done the same?

What if both tried? One could use ego | id | super-ego and one could use eros | thanatos.  Both could ignore cathexis, catharsis, resistance, introjection, repression ....

We could have a race to explain why most victims of bi-polar disorders are not cured by meditation alone or why schizophrenia [ here take your pick: strikes more at 19 than 13 or is so seldom violent paranoid or has SEEMED to have no single neural correlates.]

And by all means, do send more money.  Those who are busy squaring the circle or building perpetual motion machines are also sometimes starved for cash.  Perhaps if they were using millions of parts or drawing millions of lines they would get the attention of BBC "Tech".

But why the claim to explain schizophrenia?  Why not atheism?  Paedophilia?  Witches?

What would really matter is to explain why most schizophrenics are not violent paranoiacs.  Or not obsessed with building computer traffic simulators for crowds approaching the Roman Coliseum or wondering why "arena' would be used to name a building in which ice hockey is played - or being amused by really bad puns.

Yes, explain inveterate punning - it causes more annoyance to more people than schizophrenia.  Believe me.  Or I'll hold my breath until my brain turns blue.  Unless you pay up ...  Explain the willingness to take bribes, to turn a blind eye, and if nothing else, propose to explain the need to mock, to mock cruelly, to perseverate, to perdure in follies, to exaggerate, to fib.

The new theism in philosophy is not so new

I have been driven to a careful re-reading of the work of Paul Ricoeur to try to make sense of his relationship to Karl Jaspers - not just as philosophers, but the inner tension between the thinking of Jaspers and the hermeneutics of Ricoeur.

Ricoeur's clear preference for an open interlocutor - an interlocutor worth mentioning - has been Heidegger.  This has also been the case in the quasi-herneneutical defense of tradition in the social and political thought of Charles Taylor.  Heidegger remains the touchstone of profundity.

What I am beginning to discern in Ricoeur is that the common thread in his philosophy is simply his scarcely disguised Protestant faith - ultimately we come back to teaching the gospels and culture whose principal touchstone is the Bible.  This is not unlike the views of moderate Egyptians.  It is very clear to me that in the case of Charles Taylor, it is his abiding Catholic faith that informs his views. But in Taylor's case a return to the gospels and the Bible would first require an ecumenical development where by the churches return to the teachings of the Church.  While many imagine that they see American Lutherans merging with Episcopalians and Anglicans returning to Rome, these are now religious denominations with little growth potential in the third world in non-Catholic nations.  The vision is simply implausible.  Even if Christian, Moslem and Jew all accept their one common God, it will remain to answer to the millions in a new China why that God should be thought of as intervening in human affairs, wrecking vengeance or heeding individual prayers.  I leave the case of Hindu India aside - likely to be the most populous nation over a long period of time.

The present interest in the good prospects for confident theism and a non-theism on the defensive seems to me to be no more than a temporary set-back for secular science.  Temporary might mean decades or longer. Ultimately the the attack on science in the guise of an attack on unbridled technical intrusions into social life, the natural world and personal life will have to give way: science is not technology.  Regardless of whether we can show social progress, we will not succeed in utterly stultifying advances in mathematics, space-time theories, micro-particle theories and cosmology - not to mention genetic/molecular biology and neurology.

Even if a new wave of Ludites prevent the development of nanotech within neurology and neuro-psychology, radical change in science will be difficult to postpone.

Part of the challenge is that we have only science history at the moment - we lack sufficiently advanced simulations.  One such simulation would be one in which the telescope would be developed before any helio-centric hypothesis or any experimental methodology.  At the moment we only have one history which we can consider with regard to the development of optics.  One fascinating case is that of the discovery of the polarization of light and the technical challenge of producing quality glass.  Whether the current generation of social simulation software is moving us anywhere near being able to simulate alternative sequences of "discovery" without assumptions of either progress or the domination of nature, I leave for comment.

The shift to a non-human-centric viewpoint may be inescapable in a multiple-species animal world.  Perhaps if humans had eliminated all but plant species before the emergence of science, we could hope to avoid the species-centric challenge.  But what - in a simulation - will prevent the discovery of the octopus eye and then the discovery that some species are sensitive to polarization of light?

It is very unclear to me that observations of lunar libration and nutation could prevent the emergence of helio-centrism.  The dogma that we were taught was theoretical equivalence against like data. This has been seriously undermined in the mathematical physics of space-time - undecidability between theories will not likely be explained as a feature of fundamental science determined from first principles (empirically equivalent space-time metrics which are determined by incompatible physical theories.)  No such candidates have appeared and none should be expected.  Science remains tied to confirmation and disconfirmation of hypotheses as much as grand simplifying theoretical syntheses.  Simulations may establish that any culture which allows debate of the causes of the peculiarities of our views of the crescent moon, is a culture where geo-centrism is doomed as much as a culture which permitted the long-term Gravity Probe B experiment on frame-twisting in GTR.

Theism is of course doomed by the eventual recognition of the fate of the sun.  If our species persists, it cannot forever live in denial of the fate of the planet.  Even the strongest suppression of science is not likely to sustain academically-respectable theism indefinitely (no doubt there are theists with an indefinite eschatology or no eschatology but it would seem that barring divine intervention, their theism evntually is doomed to irrelevancy.)

The new  theists repeatedly advise us that the secular world is doomed to recognize its own meaningless divergence from genuine human culture (religion-based, naturally).  This is a mere variant on the doctrine of our tiny world once astronomy had made clear the size of this galaxy and  the numbers of the galactic clusters.  Why our tiny insignificance -if accepted as such - should or could be rescued deux ex machina is not clear to me.  I cannot see that any reflective consideration that was not already presupposing a definite theology could take any solace in the announced fate of the secular world.  I cannot see how a defense of theism is reassuring to anyone who is not already a Catholic or a Protestant or of some other definite faith.  Perhaps a new theist can explain to us the leap to Methodist rather than Presbyterian -Sunni rather than Shiite.  Buddhists of course tend to be more confidant that the thoughtful theist will see the path.  But the new theist must feel something like immense alienation from this all-powerful or all-knowing or all-explaining or all-creating being or any combination of the preceding.  It is not clear to me how a god can be expected to understand your need to believe in his need to understand you - let alone your need to implicate him in human history, human evolution or the history of the present known cosmos.  Now that you have your god, what do you plan to do, to say, to legislate (we suspect the latter.)  Why the certainty the the theos is not amused by blasphemy.  Why the need for respect?  Persons need respect.  Why the need to be recognized by us?  One suspects a familiar anthropomorphism at work.  Call it our Western tradition.

Even if theists succeed in shifting the burden to atheists in matters of justification, I cannot see that considerations of evidence or warranted belief could sway non-theists in the long term.  Anyone not born into a pre-existing religious tradition would have precisley what basis for embracing Papal infallibility and virgin birth and the physical ascension of the Virgin - let alone the Mystic Marriage - or even the Trinity?  What non-theist from Kansas could be moved by argument to embrace the panoply of gods of later, degenerate, Taoism?  Will we hold new theist councils to re-visit all of the heresies of the first few hundred years of the CE?  Will we all revert to being Messianic Jews having once been restored to theism after lapsing as Baptists or Unitarians into non-theism?

The new theism in philosophy seems to me to be nothing so very new at all: it is a comfort to pre-existing belief or very little comfort at all.  The enthusiasm with which it has been greeted has very clear parallels: the argument that the sun could not be more than 5000 years old is at the head of that pack.  What is clearly irrational is how the theism which is being defended is strong enough to move anyone raised in a Jewish home to embrace Buddhism or anyone raised in a Catholic home to embrace Islam.  What I can understand is the comfort found by those who drifted away from the faith of their childhood and now feel nostalgia in their declining years.

We are repeatedly warned not to deny people hope.  But that hope can not be hope for unrestricted economic growth or unrestricted human populations or unrestricted consumption based on carbon fuels.  But those of us who hope to live to hear some significant advance in the account of dark matter and its role in the evolution of galaxies have a hope in which a minimalist theism has very little to offer.

It is of course possible that a non-theist will advance the one impregnable line of argument for theism, offer it up to the reading public, and then collapse back in defeat leaving the field of battle to theism triumphant.  Nothing in the history of science suggests that this is a reasonable expectation.  There is just not likely to be much new in any new theism.

The biggest comfort to theists is that most non-theists identify as agnostic and not as a-theists. These agnostics tend to come from familial backgrounds with religion - but not always.  If a Catholic theist philosopher brings you to theism, are you likely to become a Baptist?  Catholics find the new theism reassuring, Protestants find the new theism reassuring and in that there is nothing so very new.
