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.

Lexit: the EU is a neoliberal project, so let's do something different when we leave it

Brexit affords the British left a historic opportunity for a decisive break with EU market liberalism.

The Brexit vote to leave the European Union has many parents, but "Lexit" – the argument for exiting the EU from the left – remains an orphan. A third of Labour voters backed Leave, but they did so without any significant leadership from the Labour Party. Left-of-centre votes proved decisive in determining the outcome of a referendum that was otherwise framed, shaped, and presented almost exclusively by the right. A proper left discussion of the issues has been, if not entirely absent, then decidedly marginal – part of a more general malaise when it comes to developing left alternatives that has begun to be corrected only recently, under Jeremy Corbyn and John McDonnell.

Ceding Brexit to the right was very nearly the most serious strategic mistake by the British left since the ‘70s. Under successive leaders Labour became so incorporated into the ideology of Europeanism as to preclude any clear-eyed critical analysis of the actually existing EU as a regulatory and trade regime pursuing deep economic integration. The same political journey that carried Labour into its technocratic embrace of the EU also resulted in the abandonment of any form of distinctive economics separate from the orthodoxies of market liberalism.

It’s been astounding to witness so many left-wingers, in meltdown over Brexit, resort to parroting liberal economics. Thus we hear that factor mobility isn’t about labour arbitrage, that public services aren’t under pressure, that we must prioritise foreign direct investment and trade. It’s little wonder Labour became so detached from its base. Such claims do not match the lived experience of ordinary people in regions of the country devastated by deindustrialisation and disinvestment.

Nor should concerns about wage stagnation and bargaining power be met with finger-wagging accusations of racism, as if the manner in which capitalism pits workers against each other hasn’t long been understood. Instead, we should be offering real solutions – including a willingness to rethink capital mobility and trade. This places us in direct conflict with the constitutionalised neoliberalism of the EU.

Only the political savvy of the leadership has enabled Labour to recover from its disastrous positioning post-referendum. Incredibly, what seemed an unbeatable electoral bloc around Theresa May has been deftly prized apart in the course of an extraordinary General Election campaign. To consolidate the political project they have initiated, Corbyn and McDonnell must now follow through with a truly radical economic programme. The place to look for inspiration is precisely the range of instruments and policy options discouraged or outright forbidden by the EU.

A neoliberal project

The fact that right-wing arguments for Leave predominated during the referendum says far more about today’s left than it does about the European Union. There has been a great deal of myth-making concerning the latter –much of it funded, directly or indirectly, by the EU itself.

From its inception, the EU has been a top-down project driven by political and administrative elites, "a protected sphere", in the judgment of the late Peter Mair, "in which policy-making can evade the constraints imposed by representative democracy". To complain about the EU’s "democratic deficit" is to have misunderstood its purpose. The main thrust of European economic policy has been to extend and deepen the market through liberalisation, privatisation, and flexiblisation, subordinating employment and social protection to goals of low inflation, debt reduction, and increased competitiveness.

Prospects for Keynesian reflationary policies, or even for pan-European economic planning – never great – soon gave way to more Hayekian conceptions. Hayek’s original insight, in The Economic Conditions of Interstate Federalism, was that free movement of capital, goods, and labour – a "single market" – among a federation of nations would severely and necessarily restrict the economic policy space available to individual members. Pro-European socialists, whose aim had been to acquire new supranational options for the regulation of capital, found themselves surrendering the tools they already possessed at home. The national road to socialism, or even to social democracy, was closed.

The direction of travel has been singular and unrelenting. To take one example, workers’ rights – a supposed EU strength – are steadily being eroded, as can be seen in landmark judgments by the European Court of Justice (ECJ) in the Viking and Laval cases, among others. In both instances, workers attempting to strike in protest at plans to replace workers from one EU country with lower-wage workers from another, were told their right to strike could not infringe upon the "four freedoms" – free movement of capital, labour, goods, and services – established by the treaties.

More broadly, on trade, financial regulation, state aid, government purchasing, public service delivery, and more, any attempt to create a different kind of economy from inside the EU has largely been forestalled by competition policy or single market regulation.

A new political economy

Given that the UK will soon be escaping the EU, what opportunities might this afford? Three policy directions immediately stand out: public ownership, industrial strategy, and procurement. In each case, EU regulation previously stood in the way of promising left strategies. In each case, the political and economic returns from bold departures from neoliberal orthodoxy after Brexit could be substantial.

While not banned outright by EU law, public ownership is severely discouraged and disadvantaged by it. ECJ interpretation of Article 106 of the Treaty on the Functioning of the European Union (TFEU) has steadily eroded public ownership options. "The ECJ", argues law professor Danny Nicol, "appears to have constructed a one-way street in favour of private-sector provision: nationalised services are prima facie suspect and must be analysed for their necessity". Sure enough, the EU has been a significant driver of privatisation, functioning like a ratchet. It’s much easier for a member state to pursue the liberalisation of sectors than to secure their (re)nationalisation. Article 59 (TFEU) specifically allows the European Council and Parliament to liberalise services. Since the ‘80s, there have been single market programmes in energy, transport, postal services, telecommunications, education, and health.

Britain has long been an extreme outlier on privatisation, responsible for 40 per cent of the total assets privatised across the OECD between 1980 and 1996. Today, however, increasing inequality, poverty, environmental degradation and the general sense of an impoverished public sphere are leading to growing calls for renewed public ownership (albeit in new, more democratic forms). Soon to be free of EU constraints, it’s time to explore an expanded and fundamentally reimagined UK public sector.

Next, Britain’s industrial production has been virtually flat since the late 1990s, with a yawning trade deficit in industrial goods. Any serious industrial strategy to address the structural weaknesses of UK manufacturing will rely on "state aid" – the nurturing of a next generation of companies through grants, interest and tax relief, guarantees, government holdings, and the provision of goods and services on a preferential basis.

Article 107 TFEU allows for state aid only if it is compatible with the internal market and does not distort competition, laying out the specific circumstances in which it could be lawful. Whether or not state aid meets these criteria is at the sole discretion of the Commission – and courts in member states are obligated to enforce the commission’s decisions. The Commission has adopted an approach that considers, among other things, the existence of market failure, the effectiveness of other options, and the impact on the market and competition, thereby allowing state aid only in exceptional circumstances.

For many parts of the UK, the challenges of industrial decline remain starkly present – entire communities are thrown on the scrap heap, with all the associated capital and carbon costs and wasted lives. It’s high time the left returned to the possibilities inherent in a proactive industrial strategy. A true community-sustaining industrial strategy would consist of the deliberate direction of capital to sectors, localities, and regions, so as to balance out market trends and prevent communities from falling into decay, while also ensuring the investment in research and development necessary to maintain a highly productive economy. Policy, in this vision, would function to re-deploy infrastructure, production facilities, and workers left unemployed because of a shutdown or increased automation.

In some cases, this might mean assistance to workers or localities to buy up facilities and keep them running under worker or community ownership. In other cases it might involve re-training workers for new skills and re-fitting facilities. A regional approach might help launch new enterprises that would eventually be spun off as worker or local community-owned firms, supporting the development of strong and vibrant network economies, perhaps on the basis of a Green New Deal. All of this will be possible post-Brexit, under a Corbyn government.

Lastly, there is procurement. Under EU law, explicitly linking public procurement to local entities or social needs is difficult. The ECJ has ruled that, even if there is no specific legislation, procurement activity must "comply with the fundamental rules of the Treaty, in particular the principle of non-discrimination on grounds of nationality". This means that all procurement contracts must be open to all bidders across the EU, and public authorities must advertise contracts widely in other EU countries. In 2004, the European Parliament and Council issued two directives establishing the criteria governing such contracts: "lowest price only" and "most economically advantageous tender".

Unleashed from EU constraints, there are major opportunities for targeting large-scale public procurement to rebuild and transform communities, cities, and regions. The vision behind the celebrated Preston Model of community wealth building – inspired by the work of our own organisation, The Democracy Collaborative, in Cleveland, Ohio – leverages public procurement and the stabilising power of place-based anchor institutions (governments, hospitals, universities) to support rooted, participatory, democratic local economies built around multipliers. In this way, public funds can be made to do "double duty"; anchoring jobs and building community wealth, reversing long-term economic decline. This suggests the viability of a very different economic approach and potential for a winning political coalition, building support for a new socialist economics from the ground up.

With the prospect of a Corbyn government now tantalisingly close, it’s imperative that Labour reconciles its policy objectives in the Brexit negotiations with its plans for a radical economic transformation and redistribution of power and wealth. Only by pursuing strategies capable of re-establishing broad control over the national economy can Labour hope to manage the coming period of pain and dislocation following Brexit. Based on new institutions and approaches and the centrality of ownership and control, democracy, and participation, we should be busy assembling the tools and strategies that will allow departure from the EU to open up new political-economic horizons in Britain and bring about the profound transformation the country so desperately wants and needs.
