âI know youâre trying to skirt around it,â says BenjamÃn Labatut when I put to him that his books concern people of unworldly intelligence working on problems that are maximally deep, âbut the best way to sum it up is: âWhy am I interested in mad scientists?ââ Fair play. Thereâs no getting away from it: thatâs exactly what his richly satisfying, deeply researched books are about.
Both of Labatutâs two books currently available in English â the International Booker-shortlisted When We Cease to Understand the World (2020) and The Maniac, recently published in paperback â pivot around that moment in the early 20th century in which our dreams of a perfect rational understanding of the world were turned on their heads. This was when the deranging discoveries of quantum physics killed off the clockwork universe; and when Kurt Gödelâs incompleteness theorem destroyed for good the positivist project to supply a stable, logically unimpeachable foundation for the rules of mathematics.
That period coincided with the birth of the atomic age and the species-wide agonies that accompanied it. The characters to whom Labatut is attracted are those who pursued these discoveries, at the cost of their peace of mind and often their sanity â figures such as Karl Schwarzschild, who did the maths that predicted the existence of black holes; or Werner Heisenberg, going half out of his mind on Helgoland; or Alexander Grothendieck, a mathematical prodigy of staggering brilliance who ended his days in the Pyrenees raving about the devil.
âItâs like mystics: they reached their Godhead,â says Labatut. âAnd, you know, God kinda whispers: âThereâs something ⦠back there.â That image of the demiurge, I think weâre coming face to face with it: we are growing up as a species, and thatâs why it feels like itâs coming to an end. Itâs been, what â since quantum mechanics and modern relativity â 100 years? One hundred years after Christ was nailed on a cross, you start to get the Gospels. Thatâs where we are.â
In the principal protagonist of The Maniac, John von Neumann, Labatut has found what he calls âthe spirit of our ageâ. Von Neumann was involved with the attempt, torpedoed by Gödel, to rethink the basis of pure maths. He was a central figure in the Manhattan Project, he designed the first recognisable computer, set out the basis of game theory and was one of the fathers of artificial intelligence. Von Neumann was also a troubled, selfish, sometimes seemingly amoral character, possessed of what Labatut calls a âcold, calculating, sharp and cutting intelligenceâ.
Religious feeling suffuses Labatutâs portraits of some of the most rational men ever to have lived. Dreaming of a secular paradise, Labatut says, we killed God and replaced him with reason â but âhumankind is never gonna rid itself of its impulse towards apotheosis; weâre driven by this thirst for the absolute thatâs cooked into our mindsâ. âEvery nymph and every god we slayed brought us more power ⦠and more despair. It just cast a bigger darkness on the world,â he says. âYou turn your eyes towards the light and youâre blinded: by AI, by tech, by going to the stars. And you turn around and you see the sort of Lovecraftian demons that are welling up from within us.â
Already a celebrity in the Spanish-speaking world, Labatut is starting to attract attention in the Anglosphere thanks to the International Booker and Barack Obamaâs endorsement. When we speak he is fresh from an on-stage interview with Stephen Fry at the Hay festival. Labatutâs first two books were in Spanish, and he collaborated closely on the English translation of When We Cease to Understand the World, but he wrote The Maniac in English, which he says âI consider my first languageâ, even though it isnât.
Asked about his continent-hopping early life, he says: âI wish it was something worth telling. But thereâs no story there at all. My dad got a job. I was born in the Netherlands, lived there till I was two, went back to Chile till I was eight, and then moved back to the Netherlands. Stayed there till I was about 15, 16. In other words my family moved around a lot more and sometimes I went with them.
âI grew up halfway between Chile and the Netherlands, speaking English â which is weird. So Iâm not really Chilean; definitely not Dutch. How do you explain to someone that you grew up watching Bottom and The Young Ones on VHS and reading Red Dwarf novels? People are like, âOh, so youâre interested in science?â Iâm like, âYeah, I read Douglas Adams when I was a kid, and from then on I cannot think in any other termsâ.â
How far is Labatut able to follow his subjects into the weeds of number theory or the Schrödinger equation? Does he actually understand the ideas in his novels of ideas? âI cannot teach my 12-year-old daughter simple mathematics,â he says. âI know nothing about mathematics. But I think a writerâs mind works with sympathy, not with understanding.â
âWhat fascinates me most is things that remain mysterious, things that are unsolved. In my books I like to invite people to go down again, to go back into darkness to enjoy this rare pleasure of being in the presence of something that as Grothendieck said is enormous and very subtle; that is quiet but, you know, raging.â
âIâm not a serious thinker,â he continues. âIâm a writer: thatâs very different. I think a writerâs intelligence has to be alive, has to be incomplete. It has to carry contradiction. It has to be sort of haphazard and amateur.â
Labatut is flamboyantly dismissive, meanwhile, of most of the things that novels (including his own) do well. When I compliment him on the way he captures his speakersâ different idioms, for instance (The Maniac is a sort of choral portrait of Von Neumann, with his teachers, friends, collaborators and wives taking turns narrating), he says: âIâm not interested. And I donât think Iâm very good at it either. Most of what people consider great writing is that talent for voices [and] character. Thatâs not something that interests me.
âIn every single chapter of that part, I am thinking that thereâs an idea I have to get across. Iâm trying to get people to be turned on by the crisis in the foundation of mathematics. Iâm trying to get people to feel the horror and beauty of the first nuclear approach.â The very idea of capturing a voice inspires him to a crescendo of outraged yelps: âTheyâre not important to me! If youâre in London, you go out there, you listen to a bunch of voices around you. Just record them and imitate them! Thatâs not difficult! I donât understand why thereâs all this crazy, âOh, we captured this.â What is difficult is for any of those characters to say something interesting!
âIâm interested in ideas,â he says. âI think so much of writing doesnât have to do with ideas. It has to do with, you know, the vicissitudes of our character. Those things bore me to death. I havenât been able to read a novel in more than a decade, probably.â Now in his mid-40s, Labatut lost his own appetite for fiction after a âcrisisâ he underwent at the age of 30, which âdamaged that part of my brain that can enjoy the games of narrativeâ.
He explains: âThe people I admire the most in every field have this wondrous ability to let their unconscious bleed into what they do. I really think that the highest form of intelligence is possession from outside. I knew that I didnât have that, so I did a bunch of very irresponsible things trying to kickstart that. And when you put yourself through that sort of ordeal, you never know what shape your mind is going to have at the end of the day. It was catastrophic for me in many ways, but it also helped pave a personal path to writing.â
Not to be intrusive, but are we talking psychedelics? âNo, itâs fine. You can be intrusive but Iâll dodge the question. Letâs just say that thereâs a bunch of modern and ancient ways to try to get past your blind spots to inspire a larger mindset, and they work. The problem is that you never know how theyâre going to work.â
If you called Labatut a practitioner of the ânonfiction novelâ, then, you could risk grouping his work with the recent explosion of autofiction â but that would be a mistake. Heâs much more like Tom McCarthy than he is like Rachel Cusk or Karl Ove KnausgÃ¥rd. He was once quoted saying he missed the days when a novelist wrote âIâ and you knew they were lying. âWasnât that lovely?â he says. âI think Bolaño said it best, right? If youâre a mass murderer, or, like, a detective in Mexico City, if you run guns with Rambo, then please, please go ahead and autofiction. If you are the worldâs best-paid sex worker, then autofiction.â
He pauses, a little mirthful. âItâs not my cup of tea. The world is so much more interesting. This art that merely reflects back what our common experiences of the world are ⦠Well, thereâs EastEnders for that.â
âBut, but â¦â I say. Voice, character, feelings, love, friendship, career â havenât these been the basic stuff of fiction since its 19th-century heyday? âIf the writing is great, it doesnât matter,â he concedes, before unexpectedly turning his disdain for the tradition into a gesture of humility. âOK. Iâm just not that good of a writer â so I have to write about interesting things. If I was a wonderful prose writer, if I was a stylist, sure: Iâd tell them who I had sex with and what I had for breakfast. But because I have never considered myself to be that good, I have to write about the most profound and confounding things out there.â
The closing section of The Maniac describes â âalmost like sports reportingâ â the triumph of AI over a human champion at the game of Go. The rise of AI is Von Neumannâs legacy, and Labatut isnât at all persuaded by the argument that itâs just âspicy autocompleteâ. âWhen you have a mathematical system that can run language, you have the two most powerful things we have developed as a species working together: mathematics and language,â he says. âI think that we are absolutely on the verge of something, if not past the verge. I think that the first AI catastrophe, because of the way things are going, massive corporations racing to the bottom, is probably inevitable.â
He adds: âThe best compliment Iâve gotten so far is people telling me, âYour book gave me a panic attack. I started feeling bad. I couldnât read it.â Or, âI finished the book, and then I saw some AI headline and I had a panic attack.â Well, come on! Books should give you a panic attack â or at least point you in that direction.â
