"Hisses, treadlings, clunks and saw-edged whines"

Some clippings from Francis Spufford's Red Plenty, while I wait for the dryer downstairs to free up. (My Kindle and my computer are rarely in the same place at the same time.) First, an overall note: it starts off wonderfully but runs out of steam, mimetically I guess. The book is about Russia between Stalin and Brezhnev; Spufford is interested in fairy tales, and wants to think of the Khrushchev era in terms of the Russian fairytale trope of the "self-victualling tablecloth"; the shoe doesn't quite fit, but comes close enough that the book isn't entirely silly. It is arranged in groups of vignettes that are each supposed to illustrate daily life in some part of this era; each group is introduced by a brief historical overview. The social range extends from low-level party workers to Khrushchev. Because the fairy tale was supposed to be powered by science, there is a lot of writing about mathematical economics and genetics and the like. I thought this was variable in quality and generally suffered from Spufford's preference for metaphors over explanations. A chapter about a scientist dying of lung cancer, in particular, narrates the progress of cancer through one's genes cells at inordinate length and with a hideous overreliance on the word "gloop." It is probably the worst science writing I have ever read -- esp. because, as I hope the clippings here and in prev. posts indicate, it's written by a remarkable prose stylist -- and deserves an award of some kind.

Nevertheless, here are the clippings:
a discordant symphony of hisses, treadlings, clunks and saw-edged whines

(about a plywood factory)
The train passed through Baltimore, Philadelphia and Jersey City, America turning its back view to him as the carriages slid athwart streets and behind rows of red-brick buildings. He gazed and speculated. It was like looking at a man facing away from you, and trying to guess what was in his pockets. He saw rusted fire-escapes clamped to the back of buildings and bundles of electrical wires in fat festoons looping from wall to wall. He saw oil storage tanks, he saw rubber tyres burning on a wasteland in a black smeech of smoke, he saw billboards advertising trinkets and cigarettes. The Americans seemed keen on neon signs, not just for important or official purposes, but everywhere they could be fitted in, violet and green and red, in humming sputtering anarchy. Troyanovsky translated some for him: MOTEL, CRAZY GOLF, JACK’S VALUE AUTO. Sometimes the view turned disconcertingly to blank virgin forest, as if America had tendrils of Siberia reaching right up into its metropolises.
(Re fire escapes, cf.)
Outside, the late summer day had become one of those evenings where the sky has the pure, clear colour of darkening water, moving to black through deeper and deeper blues.

And:
an expression of bafflement on a face like a sweating cheese

And:
Ask the computer and it would obey, as ready as a genie in a bottle – and as intolerant of badly-framed wishes.

And:
What has come over me? thought Sasha. He remembered a joke. What is a question mark? An exclamation mark in middle age.

And:
The closer a science was to practicality, the more it was co-opted into serving the practical needs of power. The closer it was to the dangerous ground of social science, on the other hand, the more distorted by ideology it tended to become. And the more abstract it was, the more intellectually uncorrupted it was likely to remain. The result was a landscape of intellectual lives laid out very differently from its counterparts abroad. Where the United States (for example) was a society ruled by lawyers, with a deep well of campus idealism among literature professors and sociologists, the Soviet Union was a society ruled by engineers, with a well of idealism among mathematicians and physicists. Law, economics, history were sterile, insignificant fiefdoms, ruled by ‘little Stalins’

And:
The car was not in good shape. The muffler banged and the gears stridulated as it lurched off the snowbank and away. Also, someone had been sick in the back and the mess had been incompletely cleaned up. Chekuskin pulled the tails of his overcoat up and sat as far as he could from it.

And:
Alexei Nikolaevich Kosygin was a neat old, solid old, dry old pol, with deep lines running from his nose to the outside corners of his upper lip, which lifted his cheeks, when he smiled, into little sardonic bunches of muscle as round as billiard balls.

And, amid the wreckage of the lung cancer chapter:
True, it is a disgusting noise he makes. It begins as a commonplace wheeze in his throat, but tumbles down into his chest where it hacks and rattles and audibly moves clots of viscous wet stuff around, till the wet stuff has been dragged up into his airway, and he’s in a gasping, gargling struggle to get it off his epiglottis, and out, so that he can breathe again. He spits into his handkerchief, clean this morning, now stiff and crusty, stained with nameless emulsions. He’s been bringing up the traditional jade mayonnaise of bronchitis every winter for as long as he can remember, but this is something different, something thicker and redder and meatier, like liquescent liver. He folds the handkerchief away, and tries to muster his persuasive powers.

Horse-science

Recent reading has thrown up a cluster of bilaterally related stuff that more thought could perhaps assemble into a complete picture. For now I'll just provide the list.

First, Michael Wood, writing about the future of universities in the LRB:
If we can’t speak the language of our enemies, not only will they not listen to us – they might not listen to us anyway – but they can’t. We need to be saying things they could hear if they would listen. ‘They’, by the way, includes all kinds of people within universities as well as outside them. But what if we can’t speak that language without losing the battle? What if the very language wins the battle by definition? What if we can’t speak of cost-effectiveness because we don’t understand either cost or effect in the way our enemies do?
Amusingly, an article about Michael Polanyi in the same issue suggests what the right language might be:
Michael thought, with few exceptions, that political meddling with a self-organising economy was wrong and destructive. (Nye notes that Michael Polanyi, Hayek and von Mises were all using the notion of ‘spontaneous order’ at that time, and while it has been claimed that Polanyi’s scientifically derived concept had priority, the usage was common in 19th-century European liberal thought.) [...] Scientific research, in its essential nature, is spontaneous, self-directing and self-organising, driven on only by its ‘internal necessities’ [...] Bernal talked of the freedom of necessity, while Polanyi asserted the necessity of freedom. Scientific autonomy had historically been a substantial fact and it had proved its rightness.

In other words, the argument against planning science -- either central or corporate -- is formally the same invisible-hand argument that the right uses to argue against planning the economy, and that "Burkeans" have used for various purposes. (It is trivial to generalize this argument to some aspects of the humanities, certainly the creative arts.) Of course, it would be silly for me to expect anyone on the contemporary right to find this persuasive, but that simply indicates the extent to which ideology is subservient to class warfare in politics (and probably has always been).

The article goes on to describe Polanyi's irrationalist defense of science:
The notion of ‘connoisseurship’ hasn’t often been attached to scientific judgment, but Polanyi repeatedly did just that: ‘Connoisseurship, like skill, can be communicated only by example, not by precept. To become an expert wine-taster, to acquire a knowledge of innumerable different blends of tea or to be trained as a medical diagnostician, you must go through a long course of experience under the guidance of a master.’ And so too to become a scientist.

Science is a vast fiduciary system. Scientists know what they do by finding trustworthy sources and then trusting them. It is also what Polanyi called a polycentric system, in which autonomous and only loosely co-ordinated groups of specialists – mildly sceptical and mainly trusting – periodically keep an eye out for what is going on next door. The coherence and integrity of the body of scientific knowledge arise through these processes of mutual adjustment. Finally, the bases of scientific judgment cannot be completely articulated because the ‘tacit dimension’ is ineliminable. It is not a fly in the formal ointment; it is what makes science science. You would understand that, Polanyi suggested, if you knew what it was to be ‘confronted with the anxious dilemma of a live scientific issue’. The further away you are from the quotidian life of scientific practice, the more you tend to be infatuated with myths of method.

Nye convincingly argues that the major purpose of Polanyi’s anti-rationalist philosophy of science was political and, specifically, that it was meant to counter Communist visions of hierarchical control. The political machinery of Communist planning proceeded through rational and formal method and it presumed rational and formal method in the object of planning. Conceptions of effective method had been devised to celebrate science, but in the middle of the 20th century they were having the unintended consequence of making people think they could command and control scientific inquiry in whatever direction they thought society needed. But you cannot plan and co-ordinate practices that are in their nature self-organising and whose most basic judgments are not formally specifiable. It was not just that a proper understanding of the nature of science was necessary to defend it; a proper understanding of science could contribute to the defence of liberal society as a whole: ‘The world needs science today above all as an example of the good life. Spread out over the planet scientists form even today, though submerged by disaster, the body of a great and good society.’ The fabric of science was political.
(When I hear "the fabric of science" I inevitably think of nylon.)

The bit in bold reminded me instantly of Michael Wood summarizing Auden:
Art can’t redeem the world, and that is why we must be modest about it. But it can show us what redemption would look like, and this is why it matters.
And thence, by a relatively short step, to Auden, in "Streams," writing about the innocent anarchic nature of water, which
    tells of a sort of world, quite other,
  altogether different from this one

with its envies and passports, a polis like that
to which, in the same of scholars everywhere,
   Gaston Paris pledged his allegiance
  as Bismarck's siege-guns came within earshot.

(There is an interesting tension here between the idea of art or science as romantic, spontaneous effusion that is implicit in this line of "spontaneous order" thinking, and the more common idea in Auden that the redemption is hard work, that it is something arrived at by a painful process of discipline. It is hard to think of redemption in non-Arcadian terms. The art/nature contrast and the planning/spontaneity contrast are not quite the same because traditional ways of life or scientific practice, which are spontaneously ordered, quite seamlessly include many very artificially organized activities. Conservatism is on this reading chiefly opposed to glibness -- David Brooks often says or implies this, but of course it is nothing if not glib to conflate this kind of view with the politics of the contemporary right.)

But to return to Polanyi. Shapin doesn't say this but his views on science are reasonably common among theoretical physicists; a good example is Steven Weinberg on scientific beauty in Dreams of a Final Theory:
A physicist who says that a theory is beautiful does not mean quite the same thing that would be meant in saying that a particular painting or a piece of music or poetry is beautiful. It is not merely a personal expression of aesthetic pleasure; it is much closer to what a horse trainer means when he looks at a racehorse and says that it is a beautiful horse. The horse trainer is of course expressing a personal opinion, but it is an opinion about an objective fact [...] that this is the kind of horse that wins races.

And elsewhere, flogging the horse metaphor on PBS:
The horse breeder has seen lots of horses and from experience with horses knows that that's the kind of horse that wins races. [...] So it's an aesthetic sense that's been beaten into us by centuries of interaction with nature.
(Weinberg's thoughts on this topic are stimulating but I disagree with them -- I think a majority of theoretical physicists nowadays would dispute the plausibility of "rigidity" as a criterion -- and I fear that it is ultimately just another example of the depressing trend where very successful people over-generalize from their success.)

I'm not sure how much weight any of these ideas individually bears, but I think they form an interesting strand in the history of 20th century liberalism.

"The psychological or human 'beginning'"

I was strongly influenced (as an undergraduate?) by this remark of Helen Vendler's about Stevens:
I do violence to these lines in detaching them from what precedes and follows them, but I do so for a reason. More often than not, the human pang in Stevens is secreted inconspicuously in the poem, instead of being announced in the title or in the opening lines. It is the usual, if mistaken, way of the commentators to begin at the beginning and take Stevens's metaphysical or epistemological prolegomena as the real subject of the poem, when in fact they are the late plural of the subject, whose early candor of desire reposes further down the page. And so I isolate what I take to be the psychological or human "beginning" of the poem, its point of origin in feeling...

This was extremely useful advice: Stevens was an acquired taste for me, and even now I find that I usually have to rearrange a Stevens poem before I can appreciate it or understand why it is put together the way it is. There is a peculiar similarity here with the business of appreciating mathematical proofs, which I was reminded of by something Gowers said in his recent (and very good) post on proving the unique prime factorization theorem:
I worry sometimes that accounts like this of how a proof might be discovered can be off-puttingly long. So it’s important to stress that the actual proofs are much much shorter. Here’s how the proof that the above thoughts lead to ends up. I’ll just do the uniqueness part, and I’ll write the whole thing in logical order, which is more or less the reverse of the order in which one discovers the steps.
I am sympathetic to the idea that real appreciation is never without an element of reverse engineering, or of hypothetical intellectual history: the completed work in itself might offer some immediate delight, but to go any further you need to have some theory, accurate or not, of how it might have been arrived at, and why it was then organized as it was. (Notable exception here: Milton. But then I think of Paradise Lost as pure verbal texture a la Campion's songs.) I imagine that this is a more tenable procedure with a poem or a proof than it is with, e.g., a novel.

It has always struck me as a regrettable deficiency -- maybe a necessary one -- of education in math and physics that there is very little intellectual history, and I think it is fair to say that many practicing physicists are not connoisseurs by temperament; there is a widespread tendency to regard historical aspects as "impractical" -- which they are, for premeds and engineers -- though I have always found it invaluable to have a sense of how people have gone about doing things. (My views on pedagogy are too uninformed and too reactionary to discuss safely in public.)

[As an admin note I'll be traveling the two weeks after Thanksgiving: Boston Nov. 26-30, New Jersey Nov. 30-Dec 2, New York that Friday night and part/all of Saturday, San Francisco Dec. 6-8. It is only mildly indiscreet to note that this is all job-quest-related to some extent; the old talk has been revised and will have to be practiced and touched up repeatedly; it is against the culture of physics to read out any part of a talk, so that, in practice, one has to memorize the first three or four agonizing minutes until one hits one's stride.]

The sieving action of facial hair

The Times (in 1853) on why construction workers shouldn't shave (TimesArchive via Marc Abrahams):

I'll transcribe part of it for searchability:
... the London masons are now growing their beards pretty generally, that the fashion is gaining ground, and will soon, in all probability, become universal. The simple action of the moustache in such case is that of a respirator, or, more correctly speaking, a species of sieve, for intercepting the passage of the dust. Besides the respirator having the effect of keeping the lungs clear of foreign particles, it also has the great advantage of preserving a steady and equable warmth around the orifice of the air passages.

I wonder what fraction of these would serve the purpose.
