Epistemology is More Important than Politics

Tuesday, April 27th, 2010

I found this interesting. It is science and technology journalist Micheal Specter at TED where he is blasting “science denial”:

I may be wrong, but I suspect that Specter’s political and perhaps, economic, views, are to the left of my own. That’s ok – he has a scientific-empirical-rational epistemology, which means there’s an intellectual common ground where debates can actually be resolved or final conclusions arrived at that can be recognized as sensible, even if disagreement based on value choices remained.

More and more, I run across people on the Left and Right using magical, tribalistic, emotionally atavistic or other variations of irrational thinking to justify their positions. Worse, this intellectual equivalent of grunting tends to be coupled with a churlishly defiant refusal to honestly consider the costs (monetary or opportunity) involved or the logical, and still less, the unintended, consequences. Am I just getting old, or is this social phenomena getting rapidly worse?

Ignorance is nothing to be ashamed of because we are all, in varying degrees, ignorant about many things. The important choice as individuals and as a society is adopting an epistemology of rational-scientific-empiricism that, if steadily applied, allows us to chip away at our ignorance and become aware of our errors and solve problems.  On the other hand, adopting a posture of belligerent, stubborn, defense of our own ignorance by evading facts, logic and the conclusions drawn from the evidence of experience is the road to certain disaster.

Our epistemic worldview matters.

Thinking With a Fresh Mind

Wednesday, April 21st, 2010

A brief anecdote.

Today, a student came to me with a question that their science instructor could not answer (the curriculum is mostly intro to chem with some classical physics). I am in no way, shape or form, a scientist or even a teacher of science, but the students know I’m interested in many odd things and like to reason through intriguing problems with them. The student asked:

“How can a photon – which has 0 mass – have 0 kinetic energy even though it is moving? If it does have mass, how can a photon go the speed of light?”

Now, I knew that the answer had to be explained via quantum mechanics and was fuzzily certain it was because particles did not behave as particles should in this scenario, but the ability to give a coherent and scientifically accurate explanation that related to the student’s current knowledge base was beyond me. I do not have a good enough grasp of the basics of quantum physics to lead the student to particles and waves through a series of questions. So, after complimenting him on his insightful question, I said I would contact an expert, Dr. Von, and get him a concise, equation-free, answer, which Von helpfully provided.

The point here, however, is not the answer (Newtonian physics is invalid at this scale and momentum is redefined in relativity theory which leads to particle-wave duality, uncertainty and other aspects of quantum mechanics) but the excellence of the student’s thinking that went into the question.

The student knew very little about physics except what was presented in the course – essentially, some laws of Newtonian physics, basic constituent parts of matter, simple atomic models etc. Given that information and having – this part is critical – no prior assumptions, having understood the “rules”, in a few minutes he identified a contradiction or paradox that undermined the authority of an elegantly constructed system of great explanatory power, conceived by the greatest genius to ever walk the Earth.

Not too shabby for a younger American teen-ager. Remember him the next time some loudmouthed fool opines how worthless kids are today or how they learn nothing at school.

Obviously, my student is quite bright, but his reasoning was also not polluted with the preconceptions we all pick up as we gain ever greater depth of mastery of a field. It was fundamentally new to him, so he did not yet have the kind of blind confidence in “the rules that everyone knows to be true” possessed by most adults and nearly all experts. He was still skeptical. Few content domain experts are innovaters for this reason. They are mostly overconfident masters with answers – not makers who create or discover the novel by asking questions. They are not skeptics, they are guardians of received knowledge.

We all need to step back, periodically, from the rush of life and our own pride and try to look at the things we think we know with a fresh mind.

Education, Books and the Digital Age

Wednesday, March 24th, 2010

 

In one of those “Socrates lamenting how the young folk can’t memorize and recite worth a damn because of all the time they waste reading!” moments, The New York Times hosted a debate of cultural significance. The authors are all thoughtful and reasonable in their contentions:

Do School Libraries Need Books?

Keeping traditional school libraries up to date is costly, with the constant need to acquire new books and to find space to store them. Yet for all that trouble, students roam the stacks less and less because they find it so much more efficient to work online. One school, Cushing Academy, made news last fall when it announced that it would give away most of its 20,000 books and transform its library into a digital center.

Do schools need to maintain traditional libraries? What are the educational consequences of having students read less on the printed page and more on the Web?

I spend a copious amount of time reading online with a PC, Blackberry, netbook and a Kindle but there’s something sad and sterile about the concept of a library without books. It is like calling a room with an iPod plugged into a Bose a “concert hall”.

This isn’t an antiquarian reaction. I am enthusiastic about the potential and the evolving reality of Web 2.0 as a powerful tool for learning, to set “minds on fire“, to facilitate mass collaboration in open-source  communities of practice, to lower costs and increase access to the highest quality educational experiences available and to drastically re-engineer public education. I am all for investing in “digital centers” for the “digital natives” – hell, all students should be carrying netbooks as a standard school supply! The capacity to skillfully navigate, evaluate and manipulate online information is not an esoteric accomplishment but an everyday skill for a globalized economy. Going online ought to be a normal part of a child’s school day, not a once a month or semester event.

I am also sympathetic to the economic questions facing school librarians – and not merely of cost, but of physical space. School library budgets are shrinking or nonexistent even as digital data compression and processing power follows Moore’s Law. Digital investment, especially when most vendors that specialize in k-12 educational markets feature egregiously oligopolistic, rip-off, prices, gives librarians an orders of magnitude larger “bang for the buck”.

But abandoning books entirely is not the way to go. Cognitively, reading online is likely not the same at the neuronal level as reading from a book. For literate adults, that may not matter as much as for children who are still in the complicated process of learning how to read. The key variable here may be visual attention moreso than particular cognitive subsets of reading skills, but we don’t actually know. Science cannot yet explain the wide developmental and methodological preference variation  among students who learn or fail to learn how to read using the ancient dead tree format. To quote neuroscientist, Dr. Maryanne Wolf:

….No one really knows the ultimate effects of an immersion in a digital medium on the young developing brain. We do know a great deal, however, about the formation of what we know as the expert reading brain that most of us possess to this point in history.

In brief, this brain learns to access and integrate within 300 milliseconds a vast array of visual, semantic, sound (or phonological), and conceptual processes, which allows us to decode and begin to comprehend a word. At that point, for most of us our circuit is automatic enough to allocate an additional precious 100 to 200 milliseconds to an even more sophisticated set of comprehension processes that allow us to connect the decoded words to inference, analogical reasoning, critical analysis, contextual knowledge, and finally, the apex of reading: our own thoughts that go beyond the text.

This is what Proust called the heart of reading – when we go beyond the author’s wisdom and enter the beginning of our own.

I have no doubt that the new mediums will accomplish many of the goals we have for the reading brain, particularly the motivation to learn to decode, read and experience the knowledge that is available. As a cognitive neuroscientist, however, I believe we need rigorous research about whether the reading circuit of our youngest members will be short-circuited, figuratively and physiologically.

For my greatest concern is that the young brain will never have the time (in milliseconds or in hours or in years) to learn to go deeper into the text after the first decoding, but rather will be pulled by the medium to ever more distracting information, sidebars, and now,perhaps, videos (in the new vooks).

The child’s imagination and children’s nascent sense of probity and introspection are no match for a medium that creates a sense of urgency to get to the next piece of stimulating information. The attention span of children may be one of the main reasons why an immersion in on-screen reading is so engaging, and it may also be why digital reading may ultimately prove antithetical to the long-in-development, reflective nature of the expert reading brain as we know it.

I could make a cultural argument about the tactile pleasure of book reading. Or the intrinsic role of books as the cornerstone of cultivating a “life of the mind” . Or that book-bound literacy is a two thousand year old element of Western civilization that is worth preserving for its own sake – which it is. However, such cultural arguments are not politically persuasive, because if you understand them already then they do not need to be made. And if you do not understand them from firsthand experience, then you cannot grasp the argument’s merit from a pious secondhand lecture.

Which leaves us with an appeal to utilitarianism; bookless schools might result in students who read poorly, which wastes money, time, opportunities and talent. Online mediums should be a regular part of a student’s diet of literacy but without books as a component of reading, a digital environment may not make for a literate people.

Guest Post: Cameron on “High Conceptual Thinkers”

Friday, March 5th, 2010

Charles Cameron, my regular guest blogger, is the former Senior Analyst with The Arlington Institute and Principal Researcher with the Center for Millennial Studies at Boston University. He specializes in forensic theology, with a deep interest in millennial, eschatological and apocalyptic religious sects of all stripes.

High Conceptual Thinkers

by Charles Cameron

This isn’t the first time I’ve seen Eric Drexler’s advice on this topic, but unless Zen mentioned it previously, or perhaps John Robb, I don’t know where I’d have seen it before. This is the part that gets to me:

Read and skim journals and textbooks that (at the moment) you only half understand. Include Science and Nature.

Don’t avoid a subject because it seems beyond you – instead, read other half-understandable journals and textbooks to absorb more vocabulary, perspective, and context, then circle back.

Each time I see that, I have to laugh. Here’s the same tale, told from the arts and humanities side of the house…

*

When I was a lad, they sent me to Wellington College, the private boarding school that prepares officers’ sons for admission to Sandhurst, and the life of a British army officer. I was not that way inclined, to be honest, and soon found myself a nice corner of the library with a comfortable chair, which I made my own.

I scanned the books in that area more closely than most, and one set of books caught my eye. It was the set of six volumes of the Eranos Yearbooks.

Eranos was a yearly gathering in Switzerland, at which CG Jung more or less presided, and at which his scholar friends read learned papers to each other at the highest levels of their own expertise.

These books night as well have been in Ge’ez, as far as I was concerned. They talked about things like “Theriomorphic Spirit Symbolism in Fairy Tales” (which is actually about gods in wild animal form, Ganesh with his elephant’s head for example), “Aeschylus: The Eumenides” about the Greek tragedy of that name, “The Spirit of Science” (that would be Erwin Schodinger speaking, which will give you an idea of the caliber of invitees) — and those are just picked from the first of the six volumes.

And how these folks went at their discussions! If a nice quote from Horace was in order, Latin’s the language. French, yes, German too, for Kant or Nietzsche. That’s okay. But Coptic? Egyptian hieroglyphs? Diagrams culled from Kabbalistic treatises about how there’s a waterfall of grace that falls constantly from G*d through ten distinct steps to the creation we inhabit, and how to climb carefully back up before the Throne?

Scattered through the six volumes were Jung, Schrodinger, Rahner, Kerenyi, Zimmer, Puesch, Quispel (between them, these two covered the waterfront on Gnostic studies), Massignon, Corbin (ditto for Islam and its mystics and martyrs), Neumann, Eliade, Tillich, Suzuki (he brought Zen to the west), Danielou, Zimmer, van der Leeuv, Wilhelm (he brought the west the I Ching), LL Whyte… I don’t believe Wolfgang Pauli ever   attended, but 400 of his dreams were discussed there under cover of anonymity by CG Jung.

I had not the least idea what these folks were on about, maybe a third of the nouns and verbs were nouns and verbs I’d never met before, and maybe a sixth of those weren’t even in my trusty Concise Oxford Dictionary: this was true scholarship, and I was aware I was in paradise.

I left that school, thankfully, and went up to Christ Church, Oxford, where I studied Theology, and learned early on that my interest was not in studying that “particular subject as if you had to pass a test on it” — I scraped by Oxford’s intense finals with what was called a “gentleman’s Third” — and I have spent the rest of my life searching out scholarship and experiences having to do with inspiration, intuition and imagination.

I’ve found myself trotting around the globe, studying now Zen then Hinduism then Lakota shamanism, at last returning to the European west via Jung and Hermann Hesse, singing Gregorian Chant under the baton of the choir master at Solesmes, meditating, sweating my buckskin out (as they say) in “stone people’s lodges”, teaching creativity in the Los Angeles atelier of a master artist, Jan Valentin Saether — and somewhere around the age of forty, I discovered the six volumes of the Eranos Yearbooks again in a second hand bookstore, and once more read them.

This time, I found they were heady but somewhat comprehensible reading, covering the entire extent of the studies to which my fascinations had led me in the intervening years — Alchemy, the Gnostics, Sufism, Zen, the Mystery cults, poetics, comparative religion, cultural anthropology, depth psychology, symbolism, the philosophy of science.

And that roll call of contributors was the roll call of half the modern masters in each of those fields.

I have the hope that I shall live to be seventy five, and read those papers as though a peer of those who assembled by the lake there in Eranos at Jung’s invitation: that those miraculous inkings of paper will at last make almost perfect sense to me, and that maybe, perhaps, it might be, may it be so — insh’allah and the creek don’t rise — I might even be able to write the odd footnote updating a passage here or there with my own insights.

Science and Nature didn’t get a look in. For me, it was Eranos all the way.

And one more story, unrelated to Eranos, but still describing my time at Wellington:

I seem to be one of those High Conceptual sorts the Eide’s are talking about — eccentric, to be sure — and I vaguely recall being hauled into the Headmaster’s office at Wellington and being accused of plagiarism, because I had written a fifteen page paper on the Contortionists of Saint Medard, the Jansenists, and Pascal. Here we go again — prior to that, I had submittedeach week three page essays on assigned topics such as “The football game” or “What I did on vacation” — but this week my English master was sick, and had   phoned in to say we could write about whatever we wanted. I’d taken him at his word, and spread my wings — and lucky for me, I could point out that the College library didn’t have enough material on the subject of the Jansenists for me to have plausibly plagiarized my essay.

Why were the strange people of Saint Medard so interesting to this young lad? Because they contorted and tortured their bodies like yogis, in what was (as far as I could tell) the first experiential attempt within Christendom to prove the hypothesis of the triumph of mind over body.

*

Now that’s all a bit selfish and introspective by way of background. But it lets you know the kinship I feel for Drexler’s crafty strategy, and likewise for the Eide’s notion of (I hesitate to write the words) “High Conceptual Thinkers”.

I want to make two points about HCTs here.

The first is to suggest that what Zen calls seeing meta-patterns is pretty much analogical / metaphorical thinking (ie lateral vs linear): the poet’s spécialité de la maison.

The second is that there exists a great project — great as in the Olympics, great as in the search for the Grand Unified Theory in physics, great as in the Italian Renaissance — for the assembly of all human cultural and scientific knowledge in a single architecture, in the form of the conceptual Glass Bead Game of Hermann Hesse.

Lewis Lapham,  in a Harper’s editorial back in 1997 said he expected the editors at Wired would soon discover Hesse’s book, and that Microsoft would want to name software in its honor.

It hasn’t happened yet. I hope it does. And that’s another story, for another day.
