The Usefulness of Useless Knowledge

Reading The Usefulness of Useless Knowledge by Abraham Flexner, and Knowledge for Sale: The neoliberal takeover of higher education by Lawrence Busch for New Scientist, 17 March 2017

 

IN 1930, the US educator Abraham Flexner set up the Institute for Advanced Study, an independent research centre in Princeton, New Jersey, where leading lights as diverse as Albert Einstein and T. S. Eliot could pursue their studies, free from everyday pressures.

For Flexner, the world was richer than the imagination could conceive and wider than ambition could encompass. The universe was full of gifts and this was why pure, “blue sky” research could not help but turn up practical results now and again, of a sort quite impossible to plan for.

So, in his 1939 essay “The usefulness of useless knowledge”, Flexner listed a few of the practical gains that have sprung from what we might, with care, term scholastic noodling. Electromagnetism was his favourite. We might add quantum physics.

Even as his institute opened its doors, the world’s biggest planned economy, the Soviet Union, was conducting a grand and opposite experiment, harnessing all the sciences for their immediate utility and problem-solving ability.

During the cold war, the vast majority of Soviet scientists were reduced to mediocrity, given only sharply defined engineering problems to solve. Flexner’s better-known affiliates, meanwhile, garnered reputations akin to those enjoyed by other mascots of Western intellectual liberty: abstract-expressionist artists and jazz musicians.

At a time when academia is once again under pressure to account for itself, the Princeton University Press reprint of Flexner’s essay is timely. Its preface, however, is another matter. Written by current institute director Robbert Dijkgraaf, it exposes our utterly instrumental times. For example, he employs junk metrics such as “more than half of all economic growth comes from innovation”. What for Flexner was a rather sardonic nod to the bottom line, has become for Dijkgraaf the entire argument – as though “pure research” simply meant “long-term investment”, and civic support came not from existential confidence and intellectual curiosity, but from scientists “sharing the latest discoveries and personal stories”. So much for escaping quotidian demands.

We do not know what the tightening of funding for scientific research that has taken place over the past 40 years would have done for Flexner’s own sense of noblesse oblige. But this we can be sure of: utilitarian approaches to higher education are dominant now, to the point of monopoly. The administrative burdens and stultifying oversight structures throttling today’s scholars come not from Soviet-style central planning, but from the application of market principles – an irony that the sociologist Lawrence Busch explores exhaustively in his monograph Knowledge for Sale.

Busch explains how the first neo-liberal thinkers sought to prevent the rise of totalitarian regimes by replacing governance with markets. Those thinkers believed that markets were safer than governments because they were cybernetic and so corrected themselves. Right?

Wrong: Busch provides ghastly disproofs of this neo-liberal vision from within the hall of academe, from bad habits such as a focus on counting citations and publication output, through fraud, to existential crises such as the shift in the ideal of education from a public to a private good. But if our ingenious, post-war market solution to the totalitarian nightmare of the 1940s has itself turned out to be a great vampire squid wrapped around the face of humanity (as journalist Matt Taibbi once described investment bank Goldman Sachs), where have we left to go?

Flexner’s solution requires from us a confidence that is hard to muster right now. We have to remember that the point of study is not to power, enable, de-glitch or otherwise save civilisation. The point of study is to create a civilisation worth saving.

Eugenic America: how to exclude almost everyone

Eugenics fails because it looks for genetic solutions to what are essentially cultural problems. The anarchist biologist Peter Kropotkin made this point as far back as 1912. Who were unfit, he asked the first international eugenics congress in London: workers or monied idlers? Those who produced degenerates in slums or those who produced degenerates in palaces?

Putting the wheel in its place

What made the rickshaw so different from a wagon or an ox-cart and, in the eyes of many Westerners, so cruel, was the idea of it being pulled by a man instead of a farm animal. Pushing wheelchairs and baby carriages posed no problem, but pulling turned a man into a beast.

Maths into English

One to Nine by Andrew Hodges and The Tiger that Isn’t by Michael Blastland and Andrew Dilnot
reviewed for the Telegraph, 22 September 2007

Twenty-four years have passed since Andrew Hodges published his biography of the mathematician Alan Turing. Hodges, a long-term member of the Mathematical Physics Research Group at Oxford, has spent the years since exploring the “twistor geometry” developed by Roger Penrose, writing music and dabbling with self-promotion.

Follow the link to One to Nine’s web page, and you will soon be stumbling over the furniture of Hodges’s other lives: his music, his sexuality, his ambitions for his self?published novel – the usual spillage. He must be immune to bathos, or blind to it. But why should he care what other people think? He knows full well that, once put in the right order, these base metals will be transformed.

“Writing,” says Hodges, “is the business of turning multi?dimensional facts and ideas into a one?dimensional string of symbols.”

One to Nine – ostensibly a simple snapshot of the mathematical world – is a virtuoso stream of consciousness containing everything important there is to say about numbers (and Vaughan Williams, and climate change, and the Pet Shop Boys) in just over 300 pages. It contains multitudes. It is cogent, charming and deeply personal, all at once.

“Dense” does not begin to describe it. There is extraordinary concision at work. Hodges covers colour space and colour perception in two or three pages. The exponential constant e requires four pages. These examples come from the extreme shallow end of the mathematical pool: there are depths here not everyone will fathom. But this is the point: One to Nine makes the unfathomable enticing and gives the reader tremendous motivation to explore further.

This is a consciously old-fashioned conceit. One to Nine is modelled on Constance Reid’s 1956 classic, From Zero to Infinity. Like Reid’s, each of Hodges’s chapters explores the ideas associated with a given number. Mathematicians are quiet iconoclasts, so this is work that each generation must do for itself.

When Hodges considers his own contributions (in particular, to the mathematics underpinning physical reality), the skin tightens over the skull: “The scientific record of the past century suggests that this chapter will soon look like faded pages from Eddington,” he writes. (Towards the end of his life, Sir Arthur Eddington, who died in 1944, assayed a “theory of everything”. Experimental evidence ran counter to his work, which today generates only intermittent interest.)

But then, mathematics “does not have much to do with optimising personal profit or pleasure as commonly understood”.

The mordant register of his prose serves Hodges as well as it served Turing all those years ago. Like Turing: the Enigma, One to Nine proceeds, by subtle indirection, to express a man through his numbers.

If you think organisations, economies or nations would be more suited to mathematical description, think again. Michael Blastland and Andrew Dilnot’s The Tiger that Isn’t contains this description of the International Passenger Survey, the organisation responsible for producing many of our immigration figures:

The ferry heaves into its journey and, equipped with their passenger vignettes, the survey team members also set off, like Attenboroughs in the undergrowth, to track down their prey, and hope they all speak English. And so the tides of people swilling about the world?… are captured for the record if they travel by sea, when skulking by slot machines, half?way through a croissant, or off to the ladies’ loo.

Their point is this: in the real world, counting is back-breaking labour. Those who sieve the world for numbers – surveyors, clinicians, statisticians and the rest – are engaged in difficult work, and the authors think it nothing short of criminal the way the rest of us misinterpret, misuse or simply ignore their hard-won results. This is a very angry and very funny book.

The authors have worked together before, on the series More or Less – BBC Radio 4’s antidote to the sort of bad mathematics that mars personal decision-making, political debate, most press releases, and not a few items from the corporation’s own news schedule.

Confusion between correlation and cause, wild errors in the estimation of risk, the misuse of averages: Blastland and Dilnot round up and dispatch whole categories of woolly thinking.

They have a positive agenda. A handful of very obvious mathematical ideas – ideas they claim (with a certain insouciance) are entirely intuitive – are all we need to wield the numbers for ourselves; with them, we will be better informed, and will make more realistic decisions.

This is one of those maths books that claims to be self?help, and on the evidence presented here, we are in dire need of it. A late chapter contains the results of a general knowledge quiz given to senior civil servants in 2005.

The questions were simple enough. Among them: what share of UK income tax is paid by the top one per cent of earners? For the record, in 2005 it was 21 per cent. Our policy?makers didn’t have a clue.

“The deepest pitfall with numbers owes nothing to the numbers themselves and much to the slack way they are treated, with carelessness all the way to contempt.”

This jolly airport read will not change all that. But it should stir things up a bit.
