In the Critics this week

Dylan Jones on David Bowie, Ed Smith on Wagner and new fiction from Deborah Levy.

In the Critics section of this week’s New Statesman, Dylan Jones, the editor of GQ, visits “David Bowie Is …” at the Victoria and Albert Museum in London. The exhibition, Jones writes, “is a proper multimedia extravaganza, and for Bowie obsessives like myself is probably the final word on the man (in a good way)”.

Our Critic at large this week is Ed Smith, who examines the enduring power of the music of Richard Wagner, whose bicentenary falls this year. Smith recalls going to a performance of Wagner’s Die Walkure at the Metropolitan Opera in New York. “The experience of Act III of Die Walkure that evening was as far removed from Hollywood shallowness as I am capable of imagining … The experience was qualitatively different from anything I’d known from watching a stage play or reading a novel.”

Deborah Levy, whose novel Swimming Home, was shortlisted for the Man Booker Prize in 2012, contributes a new short story to this issue, “Migrations to elsewhere and other aches and pains”.

In Books, Aditya Chakrabortty, economics leader writer of the Guardian, reviews Who Owns the Future by Jaron Lanier and To Save Everything, Click Here by Evgeny Morozov. Both writers, Chakrabortty argues, are in thrall to what he calls “the engineering mindset”. “If this age belongs to any profession, it surely belongs to the engineer – not in the term’s historical sense of builders of dams and railways but in its new sense of makers of technology and software.”

Also in Books: Helen Lewis reviews Fifty Shades of Feminism, edited by Lisa Appignanesi, Rachel Holmes and Susie Orbach (“In 2013, feminism is at a crucial moment”); Suzy Klein reviews Dinner with Lenny: the Last Long Interview with Leonard Bernstein by Jonathan Cott (“The genius of Cott’s book is not only to remember but to recall with pinpoint accuracy and sympathy the flame of Leonard Bernstein that burned so brightly and so true”); Andrew Biswell uncovers the story of Anthony Burgess’s lost script for the film of the James Bond novel The Spy Who Loved Me (“[The producers] probably suspected (quite rightly) that Burgess was not taking the assignment entirely seriously”); Robert Hanks reviews the reissue of Louis MacNiece’s 1938 book about London Zoo (“To read Zoo is to share with [MacNiece] a glimmer of understanding of the distance and nearness of civilisation to the state of nature”); Hannah Rosefield reviews Mohsin Hamid’s novel How to Get Filthy Rich in Rising Asia (“How to Get Filthy Rich in Rising Asia turns out to be as much moral fable as it is satire”); Jonathan Derbyshire reviews Eric Hobsbawm’s final book, Fractured Times (“Hobsbawm’s indifference the main problems of Marxist historiography … ensured that his work reached a much larger audience than that of many of his contemporaries”).

In the Books Interview, Jonathan Derbyshire talks to Lucy Wadham about her book Heads and Straights, part of the Penguin Lines series celebrating the 150th anniversary of the London Underground (“There were a number of key events in the life of my family … that had happened near Circle Line stops”).

Elsewhere in the Critics: Alexandra Coghlan talks to Sir John Eliot Gardiner about Bach (“Bach fills whatever space you allow him to enter,” Gardiner tells Coghlan); Andrew Billen reviews The Book of Mormon at the Prince of Wales Theatre in London (“It is clear … that someone has lost their nerve”); Rachel Cooke is beguiled by Michael Cockerell’s documentary about Boris Johnson (“Whatever else he is, Boris isn’t dull”); Ryan Gilbey reviews Francois Ozon’s latest film, In the House (“In the House never sacrifices its thriller credentials”); Antonia Quirke celebrates Simon Russell Beale’s radio presenting (“Not just whole programmes but whole stations happily adjust around him”).

How nature created consciousness – and our brains became minds

In From Bacteria to Bach and Back, Daniel C Dennett investigates the evolution of consciousness.

In the preface to his new book, the ­philosopher Daniel Dennett announces proudly that what we are about to read is “the sketch, the backbone, of the best scientific theory to date of how our minds came into existence”. By the end, the reader may consider it more scribble than spine – at least as far as an account of the origins of human consciousness goes. But this is still a superb book about evolution, engineering, information and design. It ranges from neuroscience to nesting birds, from computing theory to jazz, and there is something fascinating on every page.

The term “design” has a bad reputation in biology because it has been co-opted by creationists disguised as theorists of “intelligent design”. Nature is the blind watchmaker (in Richard Dawkins’s phrase), dumbly building remarkable structures through a process of random accretion and winnowing over vast spans of time. Nonetheless, Dennett argues stylishly, asking “design” questions about evolution shouldn’t be ­taboo, because “biology is reverse engin­eering”: asking what some phenomenon or structure is for is an excellent way to understand how it might have arisen.

Just as in nature there is design without a designer, so in many natural phenomena we can observe what Dennett calls “competence without comprehension”. Evolution does not understand nightingales, but it builds them; your immune system does not understand disease. Termites do not build their mounds according to blueprints, and yet the results are remarkably complex: reminiscent in one case, as Dennett notes, of Gaudí’s church the Sagrada Família. In general, evolution and its living products are saturated with competence without comprehension, with “unintelligent design”.

The question, therefore, is twofold. Why did “intelligent design” of the kind human beings exhibit – by building robotic cars or writing books – come about at all, if unintelligent design yields such impressive results? And how did the unintelligent-design process of evolution ever build intelligent designers like us in the first place? In sum, how did nature get from bacteria to Bach?

Dennett’s answer depends on memes – self-replicating units of cultural evolution, metaphorical viruses of the mind. Today we mostly use “meme” to mean something that is shared on social media, but in Richard Dawkins’s original formulation of the idea, a meme can be anything that is culturally transmitted and undergoes change: melodies, ideas, clothing fashions, ways of building pots, and so forth. Some might say that the only good example of a meme is the very idea of a meme, given that it has replicated efficiently over the years despite being of no use whatsoever to its hosts. (The biologist Stephen Jay Gould, for one, didn’t believe in memes.) But Dennett thinks that memes add something important to discussions of “cultural evolution” (a contested idea in its own right) that is not captured by established disciplines such as history or sociology.

The memes Dennett has in mind here are words: after all, they reproduce, with variation, in a changing environment (the mind of a host). Somehow, early vocalisations in our species became standardised as words. They acquired usefulness and meaning, and so, gradually, their use spread. Eventually, words became the tools that enabled our brains to reflect on what they were ­doing, thus bootstrapping themselves into full consciousness. The “meme invasion”, as Dennett puts it, “turned our brains into minds”. The idea that language had a critical role to play in the development of human consciousness is very plausible and not, in broad outline, new. The question is how much Dennett’s version leaves to explain.

Before the reader arrives at that crux, there are many useful philosophical interludes: on different senses of “why” (why as in “how come?” against why as in “what for?”), or in the “strange inversions of reasoning” offered by Darwin (the notion that competence does not require comprehension), Alan Turing (that a perfect computing machine need not know what arithmetic is) and David Hume (that causation is a projection of our minds and not something we perceive directly). Dennett suggests that the era of intelligent design may be coming to an end; after all, our best AIs, such as the ­AlphaGo program (which beat the human European champion of the boardgame Go 5-0 in a 2015 match), are these days created as learning systems that will teach themselves what to do. But our sunny and convivial host is not as worried as some about an imminent takeover by intelligent machines; the more pressing problem, he argues persuasively, is that we usually trust computerised systems to an extent they don’t deserve. His final call for critical thinking tools to be made widely available is timely and admirable. What remains puzzlingly vague to the end, however, is whether Dennett actually thinks human consciousness – the entire book’s explanandum – is real; and even what exactly he means by the term.

Dennett’s 1991 book, Consciousness Explained, seemed to some people to deny the existence of consciousness at all, so waggish critics retitled it Consciousness Explained Away. Yet it was never quite clear just what Dennett was claiming didn’t exist. In this new book, confusion persists, owing to his reluctance to define his terms. When he says “consciousness” he appears to mean reflective self-consciousness (I am aware that I am aware), whereas many other philosophers use “consciousness” to mean ordinary awareness, or experience. There ensues much sparring with straw men, as when he ridicules thinkers who assume that gorillas, say, have consciousness. They almost certainly don’t in his sense, and they almost certainly do in his opponents’ sense. (A gorilla, we may be pretty confident, has experience in the way that a volcano or a cloud does not.)

More unnecessary confusion, in which one begins to suspect Dennett takes a polemical delight, arises from his continued use of the term “illusion”. Consciousness, he has long said, is an illusion: we think we have it, but we don’t. But what is it that we are fooled into believing in? It can’t be experience itself: as the philosopher Galen Strawson has pointed out, the claim that I only seem to have experience presupposes that I really am having experience – the experience of there seeming to be something. And throughout this book, Dennett’s language implies that he thinks consciousness is real: he refers to “conscious thinking in H[omo] sapiens”, to people’s “private thoughts and experiences”, to our “proper minds, enculturated minds full of thinking tools”, and to “a ‘rich mental life’ in the sense of a conscious life like ours”.

The way in which this conscious life is allegedly illusory is finally explained in terms of a “user illusion”, such as the desktop on a computer operating system. We move files around on our screen desktop, but the way the computer works under the hood bears no relation to these pictorial metaphors. Similarly, Dennett writes, we think we are consistent “selves”, able to perceive the world as it is directly, and acting for rational reasons. But by far the bulk of what is going on in the brain is unconscious, ­low-level processing by neurons, to which we have no access. Therefore we are stuck at an ­“illusory” level, incapable of experiencing how our brains work.

This picture of our conscious mind is rather like Freud’s ego, precariously balan­ced atop a seething unconscious with an entirely different agenda. Dennett explains wonderfully what we now know, or at least compellingly theorise, about how much unconscious guessing, prediction and logical inference is done by our brains to produce even a very simple experience such as seeing a table. Still, to call our normal experience of things an “illusion” is, arguably, to privilege one level of explanation arbitrarily over another. If you ask me what is happening on my computer at the moment, I shall reply that I am writing a book review on a word processor. If I embarked instead on a description of electrical impulses running through the CPU, you would think I was being sarcastically obtuse. The normal answer is perfectly true. It’s also true that I am currently seeing my laptop screen even as this experience depends on innumerable neural processes of guessing and reconstruction.

The upshot is that, by the end of this brilliant book, the one thing that hasn’t been explained is consciousness. How does first-person experience – the experience you are having now, reading these words – arise from the electrochemical interactions of neurons? No one has even the beginnings of a plausible theory, which is why the question has been called the “Hard Problem”. Dennett’s story is that human consciousness arose because our brains were colonised by word-memes; but how did that do the trick? No explanation is forthcoming. Dennett likes to say the Hard Problem just doesn’t exist, but ignoring it won’t make it go away – even if, as his own book demonstrates, you can ignore it and still do a lot of deep and fascinating thinking about human beings and our place in nature.
