Terry Pratchett, science and story telling

The best of all possible worlds.

Terry Pratchett’s first Discworld novel was published in 1983. As a wartime child in the 1940s I was already puzzling over an image of a domed world poised on the backs of three elephants that stood on a monstrous turtle. This discworld had a small temple on top of it, and the clawed feet of the turtle rested on the coils of a huge serpent, which also stretched to encircle the world, with the point of its tail in its mouth. It was reproduced in my favourite book, Asgard and the Gods, a scholarly German work on Norse myths, which my mother had used at Cambridge.

This image, and this book, provoked my earliest thinking about the nature of belief and its relation to storytelling. Where on earth did the idea of the turtle and the elephants come from? Did people really believe in them? These questions were related to the kind of embarrassed pain with which I contemplated the stories of origins I was expected to believe in, the Bible with its heaven and hell, the tale of judgement to come.

Pratchett’s new book, The Science of Discworld IV, co-written with the mathematician Ian Stewart and the biologist Jack Cohen, discusses ideas about origins and endings, cosmology and astrobiology, entropy and genetics. The idea of storytelling is not just an embroidered way of including a tale of the discussion of the “Roundworld” taking place on the Discworld. Human beings are defined as pan narrans, the storytelling ape, who exists in a dimension known as the “narrativium”. We look for causes because we think in linear sequences of words. We look for origins because we arrange our world into narrative strings with beginning, middle and end. Stewart, Cohen and Pratchett set out to puzzle us and make us think differently.

Central to their approach is the distinction made by the physicist and sciencefiction author Gregory Benford between human-centred thinking and universecentred thinking. Human-centred thinking comes naturally to human beings. “In this world-view, rain exists in order to make crops grow and to provide fresh water for us to drink. The sun is there because it warms our bodies.” From human-centred thinking comes the idea of a ruler of the universe, as well as the idea that the earth and the creatures, the sea and the oil and the forests are somehow there for our benefit. Universe-centred thinking, on the other hand, sees human beings as “just one tiny feature of a vast cosmos, most of which does not function on a human scale or take any notice of what we want”. The universecentred thinker must have what Keats called “negative capability” – the capacity to be in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason. This is hard and invigorating.

The writers discuss creation myths – including a number of myths about cosmic turtles and scientific ideas about origins, including the Big Bang. They discuss the evolution of ideas about evolution, recent thoughts about the relation of RNA to DNA and the idea of the curvature of space. They also consider neural networks and decision theory, and the strong and weak anthropic principles – ideas about how the physical universe is uniquely suited to the existence of human beings.

Pratchett and co also explore the psychology of belief and disbelief. They describe one way of coming to conclusions – the brain taking in new evidence, and fitting it to the knowledge and beliefs it already holds. This is what they call “System 1”, and it includes scientific thinkers as well as people with inherited religious beliefs. There are, they say, scientists who “know” that DNA is the most important part of the system, physicists who “know” that the world is moving towards entropy. “System 2”, on the other hand, is steadily analytical and sceptical – “trying, not always successfully, to ignore inbuilt prejudices”. Karl Popper’s system of “critical rationalism” held that a theory could be considered scientific if, and only if, it was capable of falsification. Stewart and Cohen claim that “scientists actively try to disprove the things they would like to be true”. They use the example of a believer in UFOs who sees disbelief in UFOs as another form of belief. “Zero belief in UFOs”, they point out, is not the same as 100 per cent belief in the non-existence of UFOs. “Zero belief is an absence of belief, not an opposed form of belief.” What they aspire towards and desire is “a disbelief system”. This is exhilarating.

I remember being on a platform where various poets and writers discussed the ways in which the arts could figure the world of the scientist. That blunt sceptic Lewis Wolpert, sitting in the audience, rose to inform the assembled artists that we would not understand any of his work were we to find ourselves in his laboratory. Some of us were indignant but I believe he was right. People like me can read what is written by those scientists who try to tell us about neurons, genes, the shape of the brain, the shape of space and time. We can respond to those descriptions but we are responding to stories, at second hand.

One of the most pleasing things about Pratchett, Stewart and Cohen’s book is the way the authors demonstrate that we don’t understand even what we think we understand. I realised, reading their account of the complex relations between RNA and DNA, that I had been guilty of holding a belief. I was very excited in the late 1970s by ideas about the “selfish gene”, and particularly by the points made by John Maynard Smith about the immutable nature of the inherited and eternal germ cell. Now the New Scientist is full of articles about newly discovered “orphan DNA”. Stewart and Cohen write:

Darwin’s tree of life, a beautiful idea that derives from a sketch in The Origin of Species and has become iconic, gets very scrambled around in its roots because of a process called horizontal gene transfer. Bacteria, archaea and viruses swap genes with gay abandon, and they can also insert them into the genomes of higher animals, or cut them out. So a gene in one type of bacterium might have come from another type of bacterium altogether, or from an archaean, or even from an animal or a plant.

The story I believed in has to be modified and rethought. When I read this, I think in a human way with a series of images, in the grammar of a story. I should not be able to recognise any gene, let alone think intelligently about it. Stewart and Cohen are very good at illustrating our incapacity to understand. They do so with images and stories. My favourite is the one they tell to make us think about the difference between complicated chemistry and the “organised complexity” of the ribosome. It is a story about caramel.

Every cook knows that heating sugar with fats, two fairly simple chemical substances, produces caramel . . .  Caramel is enormously complicated on a chemical level. It includes innumerable different molecules, each of which has thousands of atoms. The molecular structure of caramel is far more complicated than most of the molecules you’re using to read this page.

But the complexity of caramel, or other complicated polymers, doesn’t produce organised complexity, as ribosomes do. Wolpert would rightly tell me that I still don’t know anything about the ribosomes. But I am at least able now to think about the problem. And the juxtaposition of caramel and brain is unforgettable. There are delights like this on most pages of this book.

In a chapter entitled “Where did that come from?” we are invited to reflect on how we can’t think about things like the origin of an oak tree, or a child, or even a thunderstorm. They make the reader imagine thinking about clouds, the constituents of the atmosphere, static electricity, physics and physical chemistry. Most of us, they say, “will not have come across one or more phrases such as ‘saturated solution’ or ‘particle carries a tiny electrical charge’. These phrases are themselves simplifications of concepts with many more associations, and more intellectual depth, than anyone can be expected to generate for themselves.” Human beings tend to retreat from uncertainty or difficulty into belief stories, like the American Republican candidate who opposed any regulation of the markets on the grounds that this was “interfering with God’s plan for the American economy”.

Pratchett, Stewart and Cohen use their method of complicating descriptions and explanations to examine several problems with things I have trouble with believing myself, because they feel to me like human stories that tidy up our relation to the universe – the Big Bang, the existence of dark matter, entropy and the “anthropic principle”. They discuss conflicting views of the expanding universe and the steady state and cast doubt on the existence of dark matter. They are not propounding or supporting any particular theory of the shape and origins of the universe, but are rather considering evidence that complicates the explanations we have become used to. They are good at picking out the operations of what they call our “very parochial” minds, which use ideas of space and time that evolved with us. “Our view of the universe may be just as parochial as the world-bearing animals of ancient cultures were. Future scientists may view both the Big Bang and four elephants riding on a turtle as conceptual errors of a very similar kind.”

In Richard Feynman’s The Character of Physical Law, they find a tendency evident in “too many physicists” to consider physical reality to be all of reality. Feynman, they write, states that “the same kind of atoms appear to be in living creatures as in non-living creatures [sic]; frogs are made of the same ‘goup’ as rocks only in different arrangements”. Things in the biological world are the results of the behaviour of physical and chemical phenomena with no “extra something.” Stewart and Cohen agree about the “no extra something” but think that a bleak view of the world of particles and elements misses out the complexity of living things, and the things they make and use and learn from.

Entropy may not be our destiny – they see Feynman rather as Pratchett sees his undifferentiated auditors, who want to tidy everything up into packets of particles. Life, say Stewart and Cohen, has “lifted itself up into a story”. That is a metaphor – and an attractive one. It feels right, and should therefore be regarded with the necessary doubt and suspicion. They also take a mocking run at the idea of “fine-tuning”, the idea that the world has evolved as the only possible world in which humans could exist – just the right amount of carbon and water, and so on.

This “anthropic principle”, in both its strong and its weak forms, has always horrified me because it is so clearly a function of the human mind thinking in a humancentred way. Isn’t it amazing, say the Discworld scientists, that our legs are just long enough to reach the ground? Isn’t it amazing that there was a hole exactly the right size to contain that puddle? And what about a sulphur-centred form of thought?

There was one chapter I found hard to understand – on the curvature of space, round worlds and disc worlds. This was where I wished the book had illustrations – I read pages about the doughnut-shaped torus, and then had the sense to consult Wikipedia, where I could see what was being discussed. And I also needed to see the geometry of the wonderful Escher image of angels and demons.

I have become rather sad about surviving into the anthropocene age of human history, where everything is controlled and constructed by and for what the King of Brobdingnag called “the most pernicious race of little odious vermin that Nature ever suffered to crawl upon the surface of the earth”. But, paradoxically, both Pratchett’s storytelling and the resolutely universecentred perspective of the scientists make me happier to be human. I look forward to the next volume.

The lost magic of England

The great conservative journalist Peregrine Worsthorne reflects on a long life at the heart of the establishment.

In a recent editorial meeting, our subscriptions manager happened to mention that Peregrine Worsthorne was still a New Statesman subscriber. A former editor of the Sunday Telegraph and, during a long Fleet Street career, a self-styled “romantic reactionary” scourge of liberals and liberalism, Worsthorne used to be something of a pantomime villain for the left, a role he delighted in. He had close friends among the “Peterhouse right”, the group of High Tory intellectuals who gathered around Maurice Cowling at the small, conspiratorial Cambridge college. He was a frequent contributor to Encounter (which turned out to be funded by the CIA) and an ardent cold warrior. His social conservatism and lofty affectations offended lefty Islingtonian sensibilities. On several occasions he was the Guardian’s reviewer of choice for its annual collection of journalism, The Bedside Guardian, and he invariably delivered the required scornful appraisal while praising its witty television critic, Nancy Banks-Smith. There is no suggestion, he wrote in 1981, that the “Guardian ever sees itself as part of the problem; itself as having some responsibility for the evils its writers described so well”.

His prose style was Oxbridge high table, more Walter Pater than George Orwell. It was essential not to take Worsthorne too seriously, because he delighted in mischief-making and wilful provocation – one of his targets for remorseless ridicule was Andrew Neil, when Neil edited the abrasively Thatcherite Sunday Times. He ended up suing Worsthorne, who was famous for his silk shirts and Garrick Club lunches, for libel; he was awarded damages of £1, the then cover price of the Sunday Times.

“I wrote that in the old days editors of distinguished Sunday papers could be found dining at All Souls, and something must have changed when they’re caught with their trousers down in a nightclub,” Worsthorne told me when we met recently. “I had no idea he was going to sue. I was teasing. I occasionally run into him and we smile at each other, so it’s all forgotten and forgiven.”

After his retirement in 1989, Worsthorne, although he remained a resolute defender of aristocracy, seemed to mellow, and even mischievously suggested that the Guardian had replaced the Times as the newspaper of record. In the 1990s he began writing occasionally for the New Statesman – the then literary editor, Peter Wilby, commissioned book reviews from him, as I did after I succeeded Wilby. Like most journalists of his generation, Worsthorne was a joy to work with; he wrote to length, delivered his copy on time and was never precious about being edited. (Bill Deedes and Tony Howard were the same.) He might have had the mannerisms of an old-style toff but he was also a tradesman, who understood that journalism was a craft.

Shortly before Christmas, I rang Wors­thorne at the home in Buckinghamshire he shares with his second wife, Lucinda Lambton, the charming architectural writer. I asked how he was. “I’m like a squeezed lemon: all used up,” he said. Lucy described him as being “frail but not ill”. I told him that I would visit, so one recent morning I did. Home is a Grade II-listed old rectory in the village of Hedgerley. It is grand but dishevelled and eccentrically furnished. A sign on the main gates warns you to “Beware of the Dog”. But the dog turns out to be blind and moves around the house uneasily, poignantly bumping into objects and walls. At lunch, a small replica mosque in the dining room issues repeated mechanised calls to prayer. “Why does it keep doing that?” Perry asks. “Isn’t it fun,” Lucy says. She then turns to me: “Have some more duck pâté.”

As a student, I used to read Worsthorne’s columns and essays with pleasure. I did not share his positions and prejudices but I admired the style in which he articulated them. “The job of journalism is not to be scholarly,” he wrote in 1989. “The most that can be achieved by an individual newspaper or journalist is the articulation of an intelligent, well-thought-out, coherent set of prejudices – ie, a moral position.”

His Sunday Telegraph, which he edited from 1986 to 1989, was like no other newspaper. The recondite and reactionary comment pages (the focus of his energies) were unapologetically High Tory, contrary to the prevailing Thatcherite orthodoxies of the time, but were mostly well written and historically literate. Bruce Anderson was one of the columnists. “You never knew what you were going to get when you opened the paper,” he told me. “Perry was a dandy, a popinjay, and of course he didn’t lack self-esteem. He had a nostalgia for Young England. In all the time I wrote for him, however, I never took his approval for granted. I always felt a tightening of the stomach muscles when I showed him something.”

***

Worsthorne is 92 now and, though his memory is failing, he remains a lucid and engaging conversationalist. Moving slowly, in short, shuffling steps, he has a long beard and retains a certain dandyish glamour. His silver hair is swept back from a high, smooth forehead. He remains a stubborn defender of the aristocracy – “Superiority is a dread word, but we are in very short supply of superiority because no one likes the word” – but the old hauteur has gone, replaced by humility and a kind of wonder and bafflement that he has endured so long and seen so much: a journalistic Lear, but one who is not raging against the dying of the light.

On arrival, I am shown through to the drawing room, where Perry sits quietly near an open fire, a copy of that morning’s Times before him. He moves to a corner armchair and passes me a copy of his book Democracy Needs Aristocracy (2005). “It’s all in there,” he says. “I’ve always thought the English aristocracy so marvellous compared to other ruling classes. It seemed to me that we had got a ruling class of such extraordinary historical excellence, which is rooted in England
almost since the Norman Conquest.

“Just read the 18th-century speeches – the great period – they’re all Whig or Tory, but all come from that [the aristocracy]. If they didn’t come directly from the aristocracy, they turned themselves very quickly into people who talk in its language. Poetic. If you read Burke, who’s the best in my view, it’s difficult not to be tempted to think what he says has a lot of truth in it . . .”

His voice fades. He has lost his way and asks what we were talking about. “Oh, yes,” he says. “It survived when others – the French and Russians and so on – were having revolutions. It was absolutely crazy to set about destroying that. There was something magical . . . the parliamentary speeches made by Burke and so on – this is a miracle! No other country has it apart from America in the early days. And I thought to get rid of it, to undermine it, was a mistake.”

I ask how exactly the aristocracy was undermined. Even today, because of the concentration of the ownership of so much land among so few and because of the enduring influence of the old families, the great schools and Oxbridge, Britain remains a peculiar hybrid: part populist hyper-democracy and part quasi-feudal state. The Tory benches are no longer filled by aristocrats but the old class structures remain.

“Equality was the order of the day after the war,” Worsthorne replies. “And in a way it did a lot of good, equalising people’s chances in the world. But it didn’t really get anywhere; the ruling class went happily on. But slowly, and I think unnecessarily dangerously, it was destroyed – and now there are no superior people around [in politics]. The Cecil family – Lord Salisbury, he was chucked out of politics. The Cecil family is being told they are not wanted. The institutions are falling apart . . .

“But there were people who had natural authority, like Denis Healey. I’m not saying it’s only aristocrats – a lot of Labour people had it. But now we haven’t got any Denis Healeys.”

Born in 1923, the younger son of Alexander Koch de Gooreynd, a Belgian banker, Worsthorne (the family anglicised its name) was educated at Stowe and was an undergraduate at both Cambridge (Peterhouse, where he studied under the historian Herbert Butterfield, the author of The Whig Interpretation of History) and Oxford (Magdalen College). “I have always felt slightly underprivileged and de-classed by having gone to Stowe, unlike my father who went to Eton,” Worsthorne wrote in 1985.

Yet his memories of Stowe remain pellucid. There he fell under the influence of the belle-lettrist John Davenport, who later became a close friend of Dylan Thomas. “He was a marvellous man, a famous intellectual of the 1930s, an ex-boxer, too. But in the war he came to Stowe and he was preparing me for a scholarship to Cambridge. He told me to read three books, and find something to alleviate the boredom of an examiner, some little thing you’ll pick up. And I duly did and got the scholarship.”

Can you remember which three books he recommended?

“Tawney. Something by Connolly, um . . . that’s the terrible thing about getting old, extremely old – you forget. And by the time you die you can’t remember your brother’s name. It’s a terrible shock. I used to think old age could be a joy because you’d have more time to read. But if you push your luck and get too far, and last too long, you start finding reading really quite difficult. The connections go, I suppose.”

Was the Connolly book Enemies of Promise (1938)?

“Yes, that’s right. It was. And the other one was . . . Hang on, the writer of the book . . . What’s the country invaded by Russia, next to Russia?

Finland, I say. Edmund Wilson’s To the Finland Station (1940)?

“Yes. Wilson. How did you get that?”

We both laugh.

***

Worsthorne is saddened but not surprised that so many Scots voted for independence and his preference is for Britain to remain a member of the European Union. “What’s happening is part of the hopelessness of English politics. It’s horrible. I can’t think why the Scots would want to be on their own but it might happen. The youth will vote [for independence]. This is part of my central theme: the Scots no longer think it’s worthwhile belonging to England. The magic of England has gone – and it’s the perversity of the Tory party to want to get us out of the European Union when of course we’re much more than ever unlikely to be able to look after ourselves as an independent state because of the quality of our political system.

“The people who want to get us out are obviously of an undesirable kind. That the future should depend on [Nigel] Farage is part of the sickness. I mean the real horror is for him to have any influence at all. And when you think of the great days of the Labour Party, the giants who strode the stage – famous, lasting historical figures, some of them: Healey, Attlee, who was probably the greatest, [Ernest] Bevin. I’m well aware that Labour in the good days produced people who were superior.”

He digresses to reflect on his wartime experience as a soldier – he served in Phantom, the special reconnaissance unit, alongside Michael Oakeshott, the philosopher of English conservatism who became a close friend, and the actor David Niven, our “prize colleague”.

“I remember Harold Macmillan saying to me, after the Second World War, the British people needed their belt enlarged; they’d done their job and they deserved a reward. And that’s what he set about doing. And he wasn’t a right-wing, unsympathetic man at all. But he didn’t – and this is what is good about conservatism – he didn’t turn it into an ‘ism’. It was a sympathetic feel, an instinctive feel, and of course people in the trenches felt it, too: solidarity with the rest of England and not just their own brotherhood. Of course he didn’t get on with Margaret Thatcher at all.”

Worsthorne admired Thatcher and believed that the “Conservatives required a dictator woman” to shake things up, though he was not a Thatcherite and denounced what he called her “bourgeois triumphalism”. He expresses regret at how the miners were treated during the bitter strike of 1984-85. “I quarrelled with her about the miners’ strike, and the people she got around her to conduct it were a pretty ropey lot.

“I liked her as a person. I was with her that last night when she wasn’t prime minister any more, but she was still in Downing Street and had everything cut off. The pressman [Bernard Ingham] got several of us to try to take her mind off her miseries that night. There’s a photograph of me standing at the top of the stairs.”

In the summer of 1989, Peregrine Wors­thorne was sacked as the editor of the Sunday Telegraph by Andrew Knight, a former journalist-turned-management enforcer, over breakfast at Claridge’s. He wrote about the experience in an elegant diary for the Spectator: “I remember well the exact moment when this thunderbolt, coming out of a blue sky, hit me. It was when the waiter had just served two perfectly poached eggs on buttered toast . . . In my mind I knew that the information just imparted was a paralysingly painful blow: pretty well a professional death sentence.”

He no longer reads the Telegraph.

“Politically they don’t have much to say of interest. But I can’t put the finger on exactly what it is I don’t like about it. Boredom, I think!”

You must read Charles Moore?

“He is my favourite. Interesting fellow. He converted to Catholicism and started riding to hounds in the same week.”

He has no regrets about pursuing a long career in journalism rather than, say, as a full-time writer or academic, like his friends Cowling and Oakeshott. “I was incredibly lucky to do journalism. What people don’t realise – and perhaps you don’t agree – but it’s really a very easy life, compared to many others. And you have good company in other journalists and so on. I was an apprentice on the Times, after working [as a sub-editor] on the Glasgow Herald.”

How does he spend the days?

“Living, I suppose. It takes an hour to get dressed because all the muscles go. Then I read the Times and get bored with it halfway through. Then there’s a meal to eat. The ­answer is, the days go. I used to go for walks but I can’t do that now. But Lucy’s getting me all kinds of instruments to facilitate people with no muscles, to help you walk. I’m very sceptical about it working, but then again, better than the alternative.”

He does not read as much as he would wish. He takes the Statesman, the Spectator and the Times but no longer the Guardian. He is reading Niall Ferguson’s biography of Kissinger, The Maisky Diaries by Ivan Maisky, Stalin’s ambassador to London from 1932 to 1943, and Living on Paper, a selection of letters by Iris Murdoch, whom he knew. “I get these massive books, thinking of a rainy day, but once I pick them up they are too heavy, physically, so they’re stacked up, begging to be read.”

He watches television – the news (we speak about Isis and the Syrian tragedy), the Marr show on Sunday mornings, and he has been enjoying War and Peace on BBC1. “Andrew Marr gave my book a very good review. He’s come back. He’s survived [a stroke] through a degree of hard willpower to get back to that job, almost as soon as he came out of surgery. But I don’t know him; he was a Guardian man.” (In fact, Marr is more closely associated with the Independent.)

Of the celebrated Peterhouse historians, both Herbert Butterfield (who was a Methodist) and Maurice Cowling were devout Christians. For High Tories, who believe in and accept natural inequalities and the organic theory of society, Christianity was a binding force that held together all social classes, as some believe was the order in late-Victorian England.

“I was a very hardened Catholic,” Worsthorne says, when I mention Cowling’s book Religion and Public Doctrine in Modern England. “My mother was divorced [her second marriage was to Montagu Norman, then the governor of the Bank of England] and she didn’t want my brother and me to be Catholic, so she sent us to Stowe. And I used to annoy her because I read [Hilaire] Belloc. I tried to annoy the history master teaching us Queen Elizabeth I. I said to him: ‘Are you covering up on her behalf: don’t you know she had syphilis?’

“Once I felt very angry about not being made Catholic. But then I went to Cambridge and there was a very Catholic chaplain and he was very snobbish. And in confession I had to tell him I masturbated twice that morning or something, and so it embarrassed me when half an hour later I had to sit next to him at breakfast. I literally gave up going to Mass to get out of this embarrassing situation. But recently I’ve started again. I haven’t actually gone to church but I’ve made my confessions, to a friendly bishop who came to the house.”

So you are a believer?

“Yes. I don’t know which bit I believe. But as Voltaire said: ‘Don’t take a risk.’”

He smiles and lowers his head. We are ready for lunch.
