Your brain on pseudoscience: the rise of popular neurobollocks

The “neuroscience” shelves in bookshops are groaning. But are the works of authors such as Malcolm Gladwell and Jonah Lehrer just self-help books dressed up in a lab coat?

An intellectual pestilence is upon us. Shop shelves groan with books purporting to explain, through snazzy brain-imaging studies, not only how thoughts and emotions function, but how politics and religion work, and what the correct answers are to age-old philosophical controversies. The dazzling real achievements of brain research are routinely pressed into service for questions they were never designed to answer. This is the plague of neuroscientism – aka neurobabble, neurobollocks, or neurotrash – and it’s everywhere.

In my book-strewn lodgings, one literally trips over volumes promising that “the deepest mysteries of what makes us who we are are gradually being unravelled” by neuroscience and cognitive psychology. (Even practising scientists sometimes make such grandiose claims for a general audience, perhaps urged on by their editors: that quotation is from the psychologist Elaine Fox’s interesting book on “the new science of optimism”, Rainy Brain, Sunny Brain, published this summer.) In general, the “neural” explanation has become a gold standard of non-fiction exegesis, adding its own brand of computer-assisted lab-coat bling to a whole new industry of intellectual quackery that affects to elucidate even complex sociocultural phenomena. Chris Mooney’s The Republican Brain: the Science of Why They Deny Science – and Reality disavows “reductionism” yet encourages readers to treat people with whom they disagree more as pathological specimens of brain biology than as rational interlocutors.

The New Atheist polemicist Sam Harris, in The Moral Landscape, interprets brain and other research as showing that there are objective moral truths, enthusiastically inferring – almost as though this were the point all along – that science proves “conservative Islam” is bad.

Happily, a new branch of the neuroscienceexplains everything genre may be created at any time by the simple expedient of adding the prefix “neuro” to whatever you are talking about. Thus, “neuroeconomics” is the latest in a long line of rhetorical attempts to sell the dismal science as a hard one; “molecular gastronomy” has now been trumped in the scientised gluttony stakes by “neurogastronomy”; students of Republican and Democratic brains are doing “neuropolitics”; literature academics practise “neurocriticism”. There is “neurotheology”, “neuromagic” (according to Sleights of Mind, an amusing book about how conjurors exploit perceptual bias) and even “neuromarketing”. Hoping it’s not too late to jump on the bandwagon, I have decided to announce that I, too, am skilled in the newly minted fields of neuroprocrastination and neuroflâneurship.

Illumination is promised on a personal as well as a political level by the junk enlightenment of the popular brain industry. How can I become more creative? How can I make better decisions? How can I be happier? Or thinner? Never fear: brain research has the answers. It is self-help armoured in hard science. Life advice is the hook for nearly all such books. (Some cram the hard sell right into the title – such as John B Arden’s Rewire Your Brain: Think Your Way to a Better Life.) Quite consistently, heir recommendations boil down to a kind of neo- Stoicism, drizzled with brain-juice. In a selfcongratulatory egalitarian age, you can no longer tell people to improve themselves morally. So self-improvement is couched in instrumental, scientifically approved terms.

The idea that a neurological explanation could exhaust the meaning of experience was already being mocked as “medical materialism” by the psychologist William James a century ago. And today’s ubiquitous rhetorical confidence about how the brain works papers over a still-enormous scientific uncertainty. Paul Fletcher, professor of health neuroscience at the University of Cambridge, says that he gets “exasperated” by much popular coverage of neuroimaging research, which assumes that “activity in a brain region is the answer to some profound question about psychological processes. This is very hard to justify given how little we currently know about what different regions of the brain actually do.” Too often, he tells me in an email correspondence, a popular writer will “opt for some sort of neuro-flapdoodle in which a highly simplistic and questionable point is accompanied by a suitably grand-sounding neural term and thus acquires a weightiness that it really doesn’t deserve. In my view, this is no different to some mountebank selling quacksalve by talking about the physics of water molecules’ memories, or a beautician talking about action liposomes.”

Shades of grey

The human brain, it is said, is the most complex object in the known universe. That a part of it “lights up” on an fMRI scan does not mean the rest is inactive; nor is it obvious what any such lighting-up indicates; nor is it straightforward to infer general lessons about life from experiments conducted under highly artificial conditions. Nor do we have the faintest clue about the biggest mystery of all – how does a lump of wet grey matter produce the conscious experience you are having right now, reading this paragraph? How come the brain gives rise to the mind? No one knows.

So, instead, here is a recipe for writing a hit popular brain book. You start each chapter with a pat anecdote about an individual’s professional or entrepreneurial success, or narrow escape from peril. You then mine the neuroscientific research for an apparently relevant specific result and narrate the experiment, perhaps interviewing the scientist involved and describing his hair. You then climax in a fit of premature extrapolation, inferring from the scientific result a calming bromide about what it is to function optimally as a modern human being. Voilà, a laboratory-sanctioned Big Idea in digestible narrative form. This is what the psychologist Christopher Chabris has named the “story-study-lesson” model, perhaps first perfected by one Malcolm Gladwell. A series of these threesomes may be packaged into a book, and then resold again and again as a stand-up act on the wonderfully lucrative corporate lecture circuit.

Such is the rigid formula of Imagine: How Creativity Works, published in March this year by the American writer Jonah Lehrer. The book is a shatteringly glib mishmash of magazine yarn, bizarrely incompetent literary criticism, inspiring business stories about mops and dolls and zany overinterpretation of research findings in neuroscience and psychology. Lehrer responded to my hostile review of the book by claiming that I thought the science he was writing about was “useless”, but such garbage needs to be denounced precisely in defence of the achievements of science. (In a sense, as Paul Fletcher points out, such books are “anti science, given that science is supposed to be  our protection against believing whatever we find most convenient, comforting or compelling”.) More recently, Lehrer admitted fabricating quotes by Bob Dylan in Imagine, which was hastily withdrawn from sale, and he resigned from his post at the New Yorker. To invent things supposedly said by the most obsessively studied popular artist of our age is a surprising gambit. Perhaps Lehrer misunderstood his own advice about creativity.

Mastering one’s own brain is also the key to survival in a dog-eat-dog corporate world, as promised by the cognitive scientist Art Markman’s Smart Thinking: How to Think Big, Innovate and Outperform Your Rivals. Meanwhile, the field (or cult) of “neurolinguistic programming” (NLP) sells techniques not only of self-overcoming but of domination over others. (According to a recent NLP handbook, you can “create virtually any and all states” in other people by using “embedded commands”.) The employee using such arcane neurowisdom will get promoted over the heads of his colleagues; the executive will discover expert-sanctioned ways to render his underlings more docile and productive, harnessing “creativity” for profit.

Waterstones now even has a display section labelled “Smart Thinking”, stocked with pop brain tracts. The true function of such books, of course, is to free readers from the responsibility of thinking for themselves. This is made eerily explicit in the psychologist Jonathan Haidt’s The Righteous Mind, published last March, which claims to show that “moral knowledge” is best obtained through “intuition” (arising from unconscious brain processing) rather than by explicit reasoning. “Anyone who values truth should stop worshipping reason,” Haidt enthuses, in a perverse manifesto for autolobotomy. I made an Olympian effort to take his advice seriously, and found myself rejecting the reasoning of his entire book.

Modern neuro-self-help pictures the brain as a kind of recalcitrant Windows PC. You know there is obscure stuff going on under the hood, so you tinker delicately with what you can see to try to coax it into working the way you want. In an earlier age, thinkers pictured the brain as a marvellously subtle clockwork mechanism, that being the cutting-edge high technology of the day. Our own brain-as-computer metaphor has been around for decades: there is the “hardware”, made up of different physical parts (the brain), and the “software”, processing routines that use different neuronal “circuits”. Updating things a bit for the kids, the evolutionary psychologist Robert Kurzban, in Why Everyone (Else) Is a Hypocrite, explains that the brain is like an iPhone running a bunch of different apps.

Such metaphors are apt to a degree, as long as you remember to get them the right way round. (Gladwell, in Blink – whose motivational selfhelp slogan is that “we can control rapid cognition” – burblingly describes the fusiform gyrus as “an incredibly sophisticated piece of brain software”, though the fusiform gyrus is a physical area of the brain, and so analogous to “hardware” not “software”.) But these writers tend to reach for just one functional story about a brain subsystem – the story that fits with their Big Idea – while ignoring other roles the same system might play. This can lead to a comical inconsistency across different books, and even within the oeuvre of a single author.

Is dopamine “the molecule of intuition”, as Jonah Lehrer risibly suggested in The Decisive Moment (2009), or is it the basis of “the neural highway that’s responsible for generating the pleasurable emotions”, as he wrote in Imagine? (Meanwhile, Susan Cain’s Quiet: the Power of Introverts in a World That Can’t Stop Talking calls dopamine the “reward chemical” and postulates that extroverts are more responsive to it.) Other recurring stars of the pop literature are the hormone oxytocin (the “love chemical”) and mirror neurons, which allegedly explain empathy. Jonathan Haidt tells the weirdly unexplanatory micro-story that, in one experiment, “The subjects used their mirror neurons, empathised, and felt the other’s pain.” If I tell you to use your mirror neurons, do you know what to do? Alternatively, can you do as Lehrer advises and “listen to” your prefrontal cortex? Self-help can be a tricky business.

Cherry-picking

Distortion of what and how much we know is bound to occur, Paul Fletcher points out, if the literature is cherry-picked.

“Having outlined your theory,” he says, “you can then cite a finding from a neuroimaging study identifying, for example, activity in a brain region such as the insula . . . You then select from among the many theories of insula function, choosing the one that best fits with your overall hypothesis, but neglecting to mention that nobody really knows what the insula does or that there are many ideas about its possible function.”

But the great movie-monster of nearly all the pop brain literature is another region: the amygdala. It is routinely described as the “ancient” or “primitive” brain, scarily atavistic. There is strong evidence for the amygdala’s role in fear, but then fear is one of the most heavily studied emotions; popularisers downplay or ignore the amygdala’s associations with the cuddlier emotions and memory. The implicit picture is of our uneasy coexistence with a beast inside the head, which needs to be controlled if we are to be happy, or at least liberal. (In The Republican Brain, Mooney suggests that “conservatives and authoritarians” might be the nasty way they are because they have a “more active amygdala”.) René Descartes located the soul in the pineal gland; the moral of modern pop neuroscience is that original sin is physical – a bestial, demonic proto-brain lurking at the heart of darkness within our own skulls. It’s an angry ghost in the machine.

Indeed, despite their technical paraphernalia of neurotransmitters and anterior temporal gyruses, modern pop brain books are offering a spiritual topography. Such is the seductive appeal of fMRI brain scans, their splashes of red, yellow and green lighting up what looks like a black intracranial vacuum. In mass culture, the fMRI scan (usually merged from several individuals) has become a secular icon, the converse of a Hubble Space Telescope image. The latter shows us awe-inspiring vistas of distant nebulae, as though painstakingly airbrushed by a sci-fi book-jacket artist; the former peers the other way, into psychedelic inner space. And the pictures, like religious icons, inspire uncritical devotion: a 2008 study, Fletcher notes, showed that “people – even neuroscience undergrads – are more likely to believe a brain scan than a bar graph”.

In The Invisible Gorilla, Christopher Chabris and his collaborator Daniel Simons advise readers to be wary of such “brain porn”, but popular magazines, science websites and books are frenzied consumers and hypers of these scans. “This is your brain on music”, announces a caption to a set of fMRI images, and we are invited to conclude that we now understand more about the experience of listening to music. The “This is your brain on” meme, it seems, is indefinitely extensible: Google results offer “This is your brain on poker”, “This is your brain on metaphor”, “This is your brain on diet soda”, “This is your brain on God” and so on, ad nauseam. I hereby volunteer to submit to a functional magnetic-resonance imaging scan while reading a stack of pop neuroscience volumes, for an illuminating series of pictures entitled This Is Your Brain on Stupid Books About Your Brain.

None of the foregoing should be taken to imply that fMRI and other brain-investigation techniques are useless: there is beautiful and amazing science in how they work and what well-designed experiments can teach us. “One of my favourites,” Fletcher says, “is the observation that one can take measures of brain activity (either using fMRI or EEG) while someone is learning . . . a list of words, and that activity can actually predict whether particular words will be remembered when the person is tested later (even the next day). This to me demonstrates something important – that observing activity in the brain can tell us something about how somebody is processing stimuli in ways that the person themselves is unable to report. With measures like that, we can begin to see how valuable it is to measure brain activity – it is giving us information that would otherwise be hidden from us.”

In this light, one might humbly venture a preliminary diagnosis of the pop brain hacks’ chronic intellectual error. It is that they misleadingly assume we always know how to interpret such “hidden” information, and that it is always more reliably meaningful than what lies in plain view. The hucksters of neuroscientism are the conspiracy theorists of the human animal, the 9/11 Truthers of the life of the mind.

The Catalan cauldron

The prospect of the break-up of Spain poses yet another challenge to Europe.

As Britain prepares to mark the centenary of the bloodiest battle in the First World War, the Somme, in July, Spain is bracing itself for an even more traumatic anniversary. In July 2016 it will be 80 years since the start of a civil war that tore the country apart and continues to divide it today. In the four decades since the return of democracy in the mid-1970s, Spaniards slowly inched towards rejecting the extreme violence of the Francoist right (and elements of the opposing left) as well as acceptance of various federal arrangements to accommodate the national sentiments of the Basques and Catalans, whose aspirations Franco had so brutally suppressed. In recent years, however, this consensus has been called fundamentally into question, with severe potential consequences not only for the unity of Spain, but the cohesion of the European Union.

On 27 October 2015, after the Catalan elections, the new parliament in Barcelona passed a declaration requesting the start of a formal secession process from Spain, to be in place in 18 months. The immediate reaction of Spain’s prime minister, Mariano Rajoy, was to announce that the state was entitled “to use any available judicial and political mechanism contained in the constitution and in the laws to defend the sovereignty of the Spanish people and of the general interest of Spain”. The preamble to the constitution proclaims the Spanish nation’s desire to “protect all Spaniards and the peoples of Spain in exercising their ­human rights, their cultures and traditions, languages and institutions”. Probably the most disputed articles are 2 and 8, which state, respectively, that “the constitution is based upon the indissoluble unity of the Spanish nation, common and indivisible patria of all Spaniards” and that “the army’s mission is to guarantee the sovereignty and independence of Spain, to defend its territorial integrity and the constitutional set-up”. Rajoy’s implication was clear: the unity of the country would be maintained, if necessary by military means.

It was Madrid, however, that broke with the federal consensus some years ago and thus boosted secessionist sentiment in Catalonia. José María Aznar’s government (1996-2004) failed to respond to demands for greater autonomy for Catalonia, at a time when secession was not even mentioned. This led to an increasing awareness among Catalans that the federal transfer system within Spain left them with an annual deficit of 8 per cent of Catalonia’s GDP because of the financial arrangements established by the Spanish state, an issue aggravated by the effect of the global financial crisis. Catalan nationalism thus became a matter of not only the heart, but also the pocket. Even more important was the Spanish legal challenge to the Statute of Autonomy of Catalonia 2006 and its subsequent dilution, after it had been sanctioned by the Catalan parliament, and by both the Spanish congress of deputies and the senate, not to mention the Catalan people in a legally binding referendum.

According to the Spanish high court of justice, some of the statute’s content did not comply with the Spanish constitution. This outraged many Catalans, who could not understand how the newly approved statute – after following all the procedures and modifications requested by Spain’s political institutions and constitution – could still be challenged. Four years later, the Spanish high court finally delivered its verdict on 28 June 2010. It removed vital points from the Statute of Autonomy 2006 and declared them non-constitutional. All this led to a revival of Catalan nationalism, culminating in a symbolic, non-binding referendum in November 2014, which was boycotted by opponents and produced a majority of 80 per cent in favour of independence.

The roots of this antagonism go deep, to the civil war that broke out on 17-18 July 1936 when some sectors of the army rebelled against the legitimate government of the Second Republic. The rebels rejected democracy, the party system, separation between church and state, and the autonomy of Catalonia, the Basque Country and Galicia. Their primary objective was to re-establish “order” by eliminating all vestiges of communism and anarchism, then quite strong in some parts of Spain.

High on the list of General Franco’s targets was Catalan nationalism, which had been growing since the late 19th century. The industrialisation of Catalonia and the Basque Country left the most economically developed parts of the Spanish state politically subject to the less prosperous Castile. By the end of the 19th century and influenced by German Romanticism, la Renaixença – a movement for national and cultural renaissance – prompted demands for Catalan autonomy, first in the form of regionalism
and later in demands for a federal state.

Catalan nationalism did not emerge as a unified phenomenon. Diverse political ideologies and cultural influences gave rise to various types of nationalism, from the conservative nationalism of Jaime Balmes to the federalism of Francesc Pi i Margall, to the Catholic nationalism of Bishop Torres i Bages and the Catalan Marxism of Andreu Nin, among others. Catalonia enjoyed some autonomy under the administrative government of the Mancomunitat or “commonwealth” from 1913 onwards. This was halted by the 1923 coup d’état of the dictator Miguel Primo de Rivera. Autonomy was granted again during the Second Spanish Republic from 1931-39 – but abolished by Francisco Franco’s decree of 5 April 1938.

Franco’s victory led to the suppression of Catalan political institutions, the banning of the Catalan language and proscription of all the symbolic elements of Catalan identity, from the national flag (the Senyera) to the national anthem (“Els Segadors”). In February 1939, the institutions of the autonomous Generalitat went into exile in France. In 1940 the Gestapo arrested the president of the Generalitat, Lluís Companys, and handed him over to Spanish officials. He was interrogated and tortured in Madrid, then sent to Barcelona, where he was court-martialled and executed at Montjuïc Castle on 15 October 1940. The most important representatives of the democratic parties banned by the regime went into exile, or were imprisoned or executed. The authoritarian state designed by Franco crushed dissent and used brute power to suppress the historical nations included within its territory. The regime’s aim was to annihilate the Catalans and the Basques as nations.

***

After almost 40 years of Franco’s dictatorship, Catalonia recovered its government, the Generalitat, in 1977 – before the drafting of the Spanish constitution in 1978 – and sanctioned a new statute of autonomy in 1979. The 2006 statute was expected, at the time, to update and expand Catalans’ aspiration for further devolution within Spain: never secession.

At present, a renewed nostalgia and enthusiasm for Francoism can be found among some sections of the Spanish right. One of the main challenges of the newly democratic government from the mid-1970s onwards was to get rid of the symbols of Francoism that had divided Spaniards between “winners” and “losers” in the civil war. It was only in 2007 that the then prime minister, José Luis Rodríguez Zapatero, guided the Law of Historic Memory through parliament with the aim of removing hundreds of Fascist symbols reminiscent of the Franco era from public buildings. It also sought to make reparations to victims of the civil war and the ensuing dictatorship.

There still exist hundreds of other references to the Fascist regime, however, with streets, colleges and roads named after Franco and his generals. The most controversial of these is the Valle de los Caídos (“Valley of the Fallen”), near Madrid, commissioned by Franco as his final resting place. It supposedly honours the civil war dead, but is primarily a monument to the general and his regime, housing the graves of Franco and José Antonio Primo de Rivera, the founder of the fascist Falange political party. Roughly 450,000 people visit it every year, and while most of them are foreign tourists, groups of Falangists and supporters of the old regime who come to pay tribute to the dictator have frequented it. Nostalgics for Francoism, though still a small minority within modern Spain, are becoming vociferous. They find common ground with far-right-wing conservatism, particularly in their shared aversion to federalism.

On 3 August last year Artur Mas, the then president of Catalonia, called an extraordinary parliamentary election after all attempts to negotiate and agree on a legally binding referendum with the Spanish government failed. Supporters of independence immediately announced that the forthcoming Catalan elections would be regarded as a plebiscite on independence.

On a turnout of more than three-quarters of the electorate, supporters of outright independence gained 48 per cent of the vote, while those backing a unitary state secured 39 per cent. On 9 November 2015 the Catalan parliament formally declared the start of the process leading to building an independent Catalan state in the form of a republic. It also proclaimed the beginning of a participative, open, integrating and active citizens’ constituent process to lay the foundations for a future Catalan constitution. The Catalan government vowed to move forward with its secession process. Immediately, the Spanish Constitutional Court suspended the Catalan law setting out a path to independence and warned that defiance could lead to criminal charges.

Worse still for Madrid, secessionism is gaining strength not only in Catalonia but also in the Basque Country, whose premier, Iñigo Urkullu, demands a “legal consultation” on the northern region’s future in Spain. He supports a new statute for the Basque Country and defends its status as a nation in the EU. Similarly to Catalonia, the Basque Country has a distinct language and culture, and benefits from the so-called concierto económico, an advantageous financial deal with the Spanish state.

***

The Spanish government’s refusal to engage constructively with Catalan nationalism contrasts markedly with London’s more relaxed and ultimately more successful response to Scottish nationalist aspirations. The “Edinburgh Agreement” between the British Prime Minister and the then first minister of Scotland to allow a binding referendum on Scottish independence stands in sharp contrast to the Spanish government’s outright opposition to a similar vote in Catalonia. Basques and Catalans find deaf ears regarding further devolution and binding referendums on self-determination. This highlights the distance between various conceptions of democracy that coexist inside the European Union, rooted in the diverse political cultures of nations with varying historical backgrounds.

All this matters, not only to Spain but to the EU, because it is part of a broad trend across the continent. In mainland Europe, demands for self-determination are running strong in Flanders as well as parts of Spain. In turn, tensions between Italy and Austria over control of South Tyrol (Trentino Alto Adige, to the Italians) remain high, as do demands advanced by the South Tyrol­ean secessionist movement. Bavarian regionalism is critical of the present German (and European) political order. Further to that, modern Venetian nationalism and its long-standing demands for independence have prompted a renewal of Venetian as a language taught in schools and spoken by almost four million people.

Matters are now coming to a head. Catalonia and Spain are in flux following two inconclusive elections. In January, after a prolonged stand-off, the sitting Catalan president, Artur Mas, made way for a fellow nationalist, Carles Puigdemont. He was the first to take the oath of office without making the traditional oath of loyalty to the Spanish constitution and the king. Felipe VI, in turn, did not congratulate Puigdemont.

The new president has announced that he plans to draw up a constitution, to be voted on in a referendum “to constitute the Catalan Republic” at the end of an 18-month consultation process. Puigdemont’s strategy envisages not a dramatic unilateral declaration
of independence, but a more gradual process of disconnection in constant dialogue with the Spanish government and Catalan political parties. Let no one be deceived by this “softly-softly” approach: it is designed to culminate, in a year and a half, perhaps sooner, in a vote on establishing a separate, sovereign state of Catalonia.

Meanwhile, Spanish politics are in flux. The elections to the Cortes on 20 December 2015 resulted in a victory for Conservatism, but also the most fragmented Spanish parliament ever and, as yet, no government. Almost the only thing the Spanish parties can agree on is opposition to Catalan independence, yet even here there are divisions over whether more autonomy should be granted and what response to make to unilateral moves by the Catalans.

The stakes are high for both sides. By pressing too hard, too early, Catalan nationalists may provoke Madrid. This would be a mistake. Strategy is important and recent events in Catalonia will weaken the Catalans’ democratic, peaceful and legitimate desire to hold a referendum on independence. Likewise, a heavy-handed response from Madrid will not only destroy the residual bonds between centre and periphery in Spain, but put the central government in the dock internationally. A confrontation will also cut across the only possible solution to this and all other national conflicts within the eurozone, which is full continental political union. Full union would render the separation of Catalonia from Spain as irrelevant to the functioning of the EU, and the inhabitants of both areas, as the separation of West Virginia from Virginia proper in the United States today.

In a nightmare scenario, radicalisation and unrest could emerge in Catalonia, with division between Catalans and memories of the Spanish Civil War coming to the fore. In this context, it might become very difficult to prevent violence.

This is the last thing that Brussels wants to hear as it grapples with the euro crisis, Russian territorial revisionism, Islamist terror, the migrant question and the prospect of Brexit. A meltdown in Catalonia will create dilemmas for Europe, starting from problems with Schengen, and raise questions about continued membership of the EU. It will also work against Catalans’ expectations of receiving EU support in their quest for independence, as turmoil in Europe will prompt nation states to close ranks. The EU will not be expected to intervene, because this scenario would – at least initially – be defined as an “internal affair of Spain”. Conflict between Barcelona and Madrid would shatter one of Europe’s biggest member states.

In that event, the peninsula will become the hottest point in an emerging “arc of crisis” across the southern flank of the EU, stretching from Portugal across Spain, an Italy struggling along with everything else to cope with the flow of migrants, the troubled Balkans, to Greece, which is perpetually perturbed. This highlights yet another flaw in the EU. It has no institutional framework for dealing with Catalan demands to become a nation within the Union, or those of other populations. Merely insisting on Spanish state sovereignty will not make the problem go away for Brussels, or for Europe as a whole. This is a potential matter of life and death not only for Spaniards and Catalans, but perhaps for the EU itself.
