It’s a sunny Sunday morning and I’m popping out to the corner shop with my little son in his pushchair. We are both in a carefree mood. But then I pass a BP petrol station, and I can’t help noticing that it’s bright green. How strange, I think to myself, to see a purveyor of pollution decked out in such an eco-friendly shade. Once inside the shop, I scan the shelves for a nice healthy treat. I’m tempted by tubs of Rachel’s Organic yoghurt, but then remember that they’re made by Dean Foods, the largest dairy company in America; and by Seeds of Change chocolate bars, inconveniently owned by Mars. You’d never know that, I note rather irritably, from the naturalistic, folksy packaging. And as I look for a newspaper to buy I see that the Times front page is sporting the headline ‘Cameron to Give Power to the People’. Is he now, I say to my slightly startled son. That’s a strange way to dress up public-spending cuts. My son’s eyes widen. He’s not yet used to my impromptu political rants. But I have always looked at the world like this. And I’ve always felt a bit critical, as though I was giving the world too much of a hard time. But the way things are going now I feel worryingly justified.

The world I see around me is one in which oil giants advertise their environmental credentials, mass-produced brands are marketed as artisanal and ethical, and a multi-millionaire Old Etonian proclaims the Conservatives the party of the poor. A world in which TV talent shows stage spectacles of against-the-odds success while rates of social mobility  drop to pre-1970s depths, Hugh Fearnley-Whittingstall catches wild sea bass while sales of ready meals reach an all-time high, and plus-size models are celebrated by the world’s media while rates of anorexia soar. We have sleepwalked into a world where nothing is as it seems; where reality, in fact, is the very opposite of appearance.

I keep hearing proclamations that we have entered a revolutionary era: of grassroots people power, a new politics, transparency and tech- nological transformation. Yet those brave new world fanfares simply do not ring true.

Is it just me, or does it seem as if new remedies are everywhere, but they’re often symptoms of a deeper malady? That despite our obses- sion with reality, we’re also in the grip of a massive sleight of hand? That we know there is something wrong, but we seem to have lost the intellectual   language   we need  in  order  to  articulate  what’s happening?

So many game-changing moments turn out to be fleeting or merely symbolic. Just as people are challenging the power of elites, those elites are speaking the language of people power in order to make even greater advances. World-altering progress is becoming increas- ingly hard to distinguish from the rhetoric of marketing.

I was checking my email recently when Windows Explorer popped up. There was the familiar list of my directories and programs, but several of them were flashing up with those dreaded red crosses. My computer was infected with a virus. The screen was instructing me to download a virus protection program that would solve the problem.

But when I Googled the name of the program, I found that it was itself a virus, something  called spyware. It had snuck into  my computer and replicated my Windows Explorer page; and download- ing the program would make things even worse. I went searching on the internet for a genuine anti-spyware program, but how could I be sure that any of those weren’t  themselves viruses? Since nobody knows how computers work any more, none of my friends could help. It was like being in a hall of mirrors from which there was no escape: the solution had turned out to be the problem in disguise. I recog- nised this sensation from somewhere, but I couldn’t quite put my finger on it. Until I realised that I recognised it from the whole of modern life.

Right now the potential for change seems overwhelming, and yet real change has also never felt less possible. At a time of such trum- peted progress, it feels as if genuine advances have slipped out of our grasp. Despite all the momentous events of recent years – the rise of the internet, the near-collapse of finance capitalism, the worldwide protests of 2011 – I do not have a sense of radical empowerment. In fact, I am puzzled, and increasingly angry; not just at the injustice of it all, but at the sense that something huge is being swept under the carpet. Liberal commentators are cheerleading the new revolution. But where I’m standing that revolution, as Gavin and Stacey would have it, is not occurring. We seem to be living our lives under the spell of a mass cognitive dissonance, and everyday existence has taken on a frustratingly unreal texture. We need to get real.  

I believe that it’s time to hold up for scrutiny the increasing gap between the appearance and the reality of our lives, and to demonstrate why it really matters, right now. I believe that we can be optimistic about progress in the world, but for me that optimism lies in critique. Because how can we solve problems if we deny their existence; if we disguise them by highlighting sparkly exceptions? How can we improve the world if we’re constantly buying into fake solutions, confected by the market- ing operations of powerful elites, determined to preserve their status? Our assumptions of choice, opportunity and accessible information lead us to consent, over and over again, to the illusions we are sold. But it doesn’t have to be that way.

So what has turned our world upside down, replacing reality with topsy-turvy mirage? In part I blame the spin, PR, marketing and rhetoric that has found its way into every nook and cranny of our lives. But we are familiar with that story, and in a sense it hides an even deeper deception. Because this is an age of apparent authenticity and realism, embedded reporters and user-generated content, HD, 3D and unbranded ‘community personality’ Starbucks cafés. Fake authenticity makes delusions doubly difficult to spot. And this is also an age in which we have swallowed the corporate line that the consumer is king, that we are savvy, self-aware and self-determining as never before. The notion that we may be duped and self-deluded, that we may be in the grip of false consciousness, is nowadays deeply taboo. But that just leaves us even more vulnerable to deception, ‘nudge’ politics and soft power, forms of manipulation that are on the rise and do not necessarily have our best interests at heart. We’re caught in a trap, as the King would have it. And we need suspicious minds.

Our delusions are sustained by a seamless blurring of deception and collusion. When people talk about conspiracy theories, the assumption is that there are evil agents doing the conspiring. But the conspiracies I’m interested in are really diffuse. We are both agents and victims, and our compliance with soft power comes about through unconscious creeping cooperation. It’s in the drinking water.

I am, however, passionately committed to the idea that decoding delusions can help us to loosen their limiting grip on our lives, and take action  to  improve  our  world for  real. Because it’s these whitewashed problems and illusory solutions that are responsible for our curious sense of paralysis. But we can see through them if we look hard enough.

There’s another factor at play. With the melting away of conflicts between East and West in the Cold War and Right and Left in our politics, the big ideologies have been consigned to history. The influential political scientist Francis Fukuyama hailed ‘the end of history’ and the triumph of capitalist democracy. But I believe that agendas never really disappeared. They just began to operate undercover, leaving us with a looking-glass world in which reality is spun and vested interests appear in disguise. Politicians now regard the word ‘ideology’ as an insult, but they are driven by ideology none- theless. It’s now a covert form of ideology that’s at work, and that we ignore at our peril. It’s time to regard ideology as the heart of the problem, but also the potential solution.

Because if we want to improve our world – indeed, with the environmental challenges we face, to save it – we need not only to identify hidden agendas, but also to have explicit aspirations. We need not to be afraid to say what we mean and what we mean to do. If we’re too credulous in some ways, we also don’t believe in enough. We need to debunk delusions and reclaim ideology as positive idealism, otherwise people power and revolution will remain empty ciphers that serve to obscure the lack of real agency and real change.
