Alexei Sayle on what makes us human: We need to realise that the best things in life are not things

Continuing our What Makes Us Human series, Alexei Sayle reflects on the time Paul McKenna planted a suicidal post-hypnotic suggestion in his brain, and how our restlessness has been exploited to devastating effect.

Several years ago I attended a summer party where one of the other guests was the stage hypnotist and motivational speaker Paul McKenna. For some reason we got talking about environmental issues in which I know he has an interest. I was talking about how so much of my own and other people’s supposed environmental activity such as recycling wine bottles or buying organic bread is just a mask for continuing rampant consumerism and he replied, “Yes, if you were truly serious about trying to save the planet then what you would do, would be you would kill yourself.”

I had never heard this opinion expressed before. As the child of communists and a vestigial Marxist myself, my belief had always been that mankind’s depredation of the planet was as a result of our exploitative economic system. I had unthinkingly subscribed to the view that capitalism was the problem and if we had a different, fairer economic system – such as socialism – then we could heal the scars we have inflicted on the earth in pursuit of the wilder excesses of capitalist consumerism. Socialist man would walk arm and arm with nature into a kinder, greener future.

But what McKenna seemed to be saying was that what makes us human also makes us destroyers of the earth, and that – given human nature – there is no way that we could live in harmony with the environment. Therefore the only hope for the planet was if mankind disappeared completely. Once we had disappeared from the face of the planet a great peace would descend – wars would stop, the destruction of the rainforest would be halted and gradually green growth would cover the landscape scarred with our buildings. The beauty of this wonderful blue-green planet would be restored and its only inhabitants – the animals –would live in harmony with Gaia.

A few days later I was having my breakfast and I was chewing on a piece of toast when the unbidden thought popped into my head, “This toast is a bit dry. I might as well hang myself.” Of course, this was Paul McKenna who at the party had clearly planted a suicidal post-hypnotic suggestion in my brain. I managed to avoid committing suicide but continued to wonder whether to be human means that I will inevitably be part of destroying the natural world. Or is there some way in which we can live in harmony with the earth?

Given that every other creature except us has always had a benign relationship with the planet, and that before the invention of agriculture we did, too, and that there remain tribal societies in a few remote corners of the earth that still do no harm to the biosphere while the vast majority of us live profoundly unnatural lives, how did this come about? And can we reverse at least some of the worst effects of what it is to be part of the disease that makes us human in the 21st century?

Pascal said: “All of humanity’s problems stem from man’s inability to sit quietly in a room alone.” And that has got to be at the root of what has gone wrong with our relationship to our environment. We can’t leave well alone; we are never satisfied. This perpetual search for novelty may have made us reach for the stars but it has also led us constantly to seek the better, bigger exercise bike. Capitalism has seized on this flaw in our make-up and refined it so that we think that happiness will come from the next thing – the very next thing – that we buy. Our last phone did not make us happy but this new one with a 13 billion-pixel camera will. Or, if only I had the £300 pair of trainers instead of these crappy ones that I bought last week for £129. Why did I ever imagine they would make me happy?

What obsesses all industrial societies is ceaseless growth, making more and more things, building more and more buildings, eating more and more food. Without continuous expansion, all manufacturing economies will collapse. And in order to continue this expansion, people must be convinced that their happiness lies in buying new stuff. So what makes us human right now in the industrial economies is to be permanently dissatisfied, because, for our economies to grow, we must believe that it is not any of the things we own but the very next thing we buy, the very next holiday we take, that will finally push us over the top into serenity.

Of course, as soon as we buy the thing or finish the holiday, that sense of dissatisfaction returns. The happiness doesn’t last but what is continuous and increasing is the brutal excavation of the earth’s finite resources.

Millennia ago, in pre-agrarian societies, one day was much like another and people lived together in harmony with each other and with nature. There existed a primitive form of communism: since there were no surpluses, nobody could accumulate more possessions than anybody else. And without more possessions there was no incentive to grab more power; decisions were reached more or less by consensus.

We are never going to get back to this Garden of Eden but surely it should be possible to live more in harmony with both our planet and our better, truer selves? The thousand-year experiment to see if happiness can be bought, if possession of more and more stuff can give life meaning, has failed. We need to realise that the best things in life are not things. Perhaps we need to look at and learn from the animal world: few animals living in freedom fail to reach their full potential. To quote D H Lawrence: “If men were as much men as lizards are lizards/they’d be worth looking at.”

3D cinema without the glasses: a potential new technology could change how we watch films

Early-stage research success hints at a visionary future in which an immersive glass-free 3D experience could be possible at the cinema. 

The rise of film-on-demand streaming sites such as Netflix and MUBI threatens to make visits to the cinema a redundant pastime; why head out to watch a film when you can just watch one from the comfort of your own home?

A deterrent for many has been the influx of 3D blockbuster films released in theatres. An all-too-familiar routine has developed that causes audiences to let out a big sigh at the thought of 3D films: get excited about the latest Marvel flick, travel to your local cinema, sit through previews of future releases and then as the film is about to start...stick on a pair of flimsy plastic 3D glasses.

It’s an experience that has come to feel lacklustre for people who hope to experience more from 3D technology than just a gimmick. However, recent news that researchers at MIT have developed a prototype screen which can show 3D films without glasses may be just the development needed for the medium to attract fans back to the cinema.

A team of scientists from MIT’s Computer Science and Artificial Intelligence Lab paired up with the Weizmann Institute of Science from Israel to create “Cinema 3D” – a model cinema screen which could potentially allow cinema-goers to have the full, immersive 3D experience sans glasses, no matter where they are sitting in the theatre.

Detailing their research in a paper, the scientists outlined the technology used, which includes “automultiscopic displays” – a 3D enabler that presents “multiple angular images of the same scene” and doesn’t require glasses. The research has had to build upon conventional automultiscopic displays that alone aren’t sufficient for a cinema setting; they don’t accommodate for the varying angles at which people view a film in a generally widely-spaced theatre

Wojciech Matusik, an MIT professor who worked on the research said: “Existing approaches to glasses-free 3D require screens whose resolution requirements are so enormous that they are completely impractical. This is the first technical approach that allows for glasses-free 3D on a larger scale.”

Cinema 3D aims to optimise the experience by making use of the cinema setting: the fixed seat positions, the sloped rows, the width of the screen. 3D televisions work as a result of parallax barriers – essentially a set of slits in front of a screen that filter pixels to create the illusion of depth. Traditional parallax barriers tend to fail with anything larger than a television, as they don’t recreate the same image when viewed from different distances and angles.

The researchers have combated this by using multiple parallax barriers in conjunction with slanted horizontal mirrors and vertical lenslets – a small but crucial change which now allows viewers to see the same 3D images play out, whether they’re in the middle row, the back row, or far off in the periphery. According the paper, the design “only displays the narrow angular range observed within the limited width of a single seat.” This can then be replicated for every seat in the theatre.

Cinema 3D will require a lot more work if it is to become practical. As it stands, the prototype is about a pad of paper in size and needs 50 sets of mirrors and lenses. For the researchers though, there is reason to remain optimistic as the technology works in theory at a cinema-scale.

It’s important to note that 3d technology without glasses isn’t new; it has been used in a limited way with televisions. What is new with this research is its potential application to the film industry along with improvements in picture quality. Matusik has stressed that “it remains to be seen whether the approach is financially feasible enough to scale up to a full-blown theatre”, but went on to say “we are optimistic that this is an important next step in developing glasses-free 3D for large spaces like movie theatres and auditoriums.”

It could take a while for the technology to get to a stage where it can be used in multiplexes, and the market may need convincing to adopt something which is expected to cost a lot of money. It could prove to be attractive to the advertising industry who may want to use it for billboards, allowing the technology to be introduced at incrementally larger stages.

The thought of seeing James Cameron’s next Avatar instalment or the latest high-octane thriller played out in 3D without glasses could push the technology forward and get people to return in droves to the silver screen.
