Do you ever get the feeling that we're living in a postmodern fiction? You’re not alone | Dan Brooks

Writing about the assassination of President John F Kennedy for Rolling Stone in 1983, 20 years after the shooting, the novelist Don DeLillo remarked : “Europeans and Middle Easterners are notoriously prone to believe in conspiracies … Americans, for their own good reasons, tend to believe in lone gunmen.” How times change. Since Donald Trump was wounded in an assassination attempt on 13 July, social media have boiled over with talk of conspiracies, false flags and complex manipulations of state and psyche for unclear ends. After Joe Biden withdrew his candidacy for president, various online conservatives argued that he was actually dead . Meanwhile, otherwise sensible observers blamed the media for creating the narrative that Biden had lost mental acuity and keeping Trump in the public eye – a kind of Rothschild conspiracy for people who took undergraduate sociology.

It’s fun to scoff at such people, who believe that powerful forces secretly organise the world even as we confront evidence that human intelligence is no longer sufficient to run a branch of Chipotle. In fairness to the paranoid mindset, though, a lot of events from earlier decades’ fiction have been coming true lately. Consider Lisa’s prophetic line from the Bart to the Future episode of The Simpsons, original airdate 19 March 2000: “As you know, we’ve inherited quite a budget crunch from President Trump.” It was funny at the time. I believe it was either Karl Marx or Nelson Muntz who said that history repeats itself: first as farce, then as whatever all this is now.

The other week, Twitter user @ZeroSuitCamus posted a passage from an essay JG Ballard wrote for Vogue in the 1970s (incorrectly attributed to his 1975 novel High-Rise) about a future in which our daily activities are all recorded on video, and every evening “we sit back to scan the rushes, selected by a computer trained to pick out only our best profiles, our wittiest dialogue, our most affecting expressions filmed through the kindest filters …” Here is the Instagram experience and its strange effects, complete with filter, algorithm and night-time scrolling, delivered to us decades before it became reality. David Foster Wallace predicted the filter, too, around page 111 of Infinite Jest, in which internet-enabled video calling makes everyone so insecure about their faces that they briefly adopt electronic face-improving technology, before it develops such a stigma that they all go back to voice-only telephony. Wallace’s 1996 novel about a form of entertainment so fascinating that it amuses its viewers to death raises some uncomfortable questions for any reader who gets screen time updates on their phones.

All these texts – DeLillo, Ballard and Wallace for sure, and The Simpsons, too, in my opinion – fall under the category of “postmodernism”. The contours of the genre are still debated many decades after it emerged, but two key themes on which critics agree are (1) characters who find themselves at the mercy of impossibly complex systems; and (2) a sincere effort to acknowledge the importance of texts in modern life, which has since curdled into mere referentiality. I submit that these themes are no longer limited to literature and have become defining aspects of the way we live now.

I also submit that it’s kind of weird that we have identified our own time as “postmodern” for three generations running. In the same way that the term “modernism” tells you something about how people thought of themselves in the years after the first world war, the fact that we regard ourselves as “post-” suggests a certain mindset. In many ways, our culture thinks of itself as existing after the important part of history – increasingly, after the good part. Latter-days thinking prevails, particularly on social media and in the arts, which seems resigned to rearranging the material already provided to us.

I don’t think many of us are delighted to see previous generations’ satires coming true. Stories about technology-driven anomie and lives that had become unmoored from meaningful values were thrilling to readers in the 1980s and 1990s, but to be a character in such stories is a different thing. At the same time, we aren’t kicking against it – at least not much. There is that postmodern sense that the systems governing our world are too big and complex to do anything about them. We are all in a self-driving car that is taking us somewhere we don’t want to go.

The bad news is that the conspiracy theories are false, and the car keeps veering toward pedestrians not because California billionaires are secretly priming the public for mandatory bicycles, but rather because someone saved money by skimping on quality control. Incompetence is more common than malice, even though it makes for a less compelling plot. The good news is that the sense that our world has become a work of postmodern fiction is also false. If it sometimes feels unpleasant to believe that what is happening in the news is real, it is also vital to remember that we are not characters in a story. What happens next is not written, even in outline form.

The impossibly big systems are real and in many cases evil, as anyone who has travelled by air in recent years will attest. But they are nonetheless our systems, made and not given, and they can be remade. The end of the postmodern era will come not when the last Simpsons joke comes true, but when we realise the world imagined by the previous century is not enough for us – entertaining and fun to talk about, sure, but fundamentally less interesting than what we can come up with. Sooner or later, we must become authors again.
