Most successful stories remain open-ended. They never need to explain where meaning ultimately comes from, because they are so good at capturing people’s attention and keeping it inside a safe zone. Thus when explaining that the world rests on the back of a huge elephant, you should pre-empt any difficult questions by describing in great detail that when the elephant’s gigantic ears flap they cause hurricanes, and when the elephant quivers with anger earthquakes shake the surface of the earth. If you weave a good enough yarn, it won’t occur to anyone to ask what the elephant is standing on. Similarly, nationalism enchants us with tales of heroism, moves us to tears by recounting past disasters, and ignites our fury by dwelling on the injustices our nation suffered. We get so absorbed in this national epic that we start evaluating everything that happens in the world by its impact on our nation, and hardly think of asking what makes our nation so important in the first place.
When you believe a particular story, it makes you extremely interested in its minutest details, while keeping you blind to anything that falls outside its scope. Devout communists may spend countless hours debating whether it is permissible to make an alliance with social democrats in the early stages of revolution, but they seldom stop to ponder the place of the proletariat in the evolution of mammalian life on planet Earth or in the spread of organic life in the cosmos. Such idle talk is considered a counter-revolutionary waste of breath.
Though some stories go to the trouble of encompassing the entirety of space and time, the ability to control attention allows many other successful stories to remain far more modest in scope. A crucial law of storytelling is that once a story manages to extend beyond the audience’s horizon, its ultimate scope matters little. People may display the same murderous fanaticism for the sake of a thousand-year-old nation as for the sake of a billion-year-old god. People are just not good with large numbers. In most cases, it takes surprisingly little to exhaust our imagination.
Given everything we know about the universe it would seem utterly impossible for any sane person to believe that the ultimate truth about the universe and human existence is the story of Israeli, German or Russian nationalism – or indeed of nationalism in general. A story that ignores almost the whole of time, the whole of space, the Big Bang, quantum physics and the evolution of life is at most just a tiny part of the truth. Yet people somehow manage not to see beyond it.
Indeed, billions of people throughout history have believed that for their lives to have meaning, they don’t even need to be absorbed into a nation or a great ideological movement. It is enough if they just ‘leave something behind’, thereby ensuring that their personal story continues beyond their death. The ‘something’ I leave behind is ideally my soul or my personal essence. If I am reborn in a new body after the death of my present body, then death is not the end. It is merely the space between two chapters, and the plot that began in one chapter will carry on into the next. Many people have at least a vague faith in such a theory, even if they do not base it on any specific theology. They don’t need an elaborate dogma – they just need the reassuring feeling that their story continues beyond the horizon of death.
This theory of life as a never-ending epic is extremely attractive and common, but it suffers from two main problems. First, by lengthening my personal story I don’t really make it more meaningful. I just make it longer. Indeed, the two great religions that embrace the idea of a never-ending cycle of births and deaths – Hinduism and Buddhism – share a horror of the futility of it all. Millions upon millions of times I learn how to walk, I grow up, I fight with my mother-in-law, I get sick, I die – and then do it all over again. What’s the point? If I accumulated all the tears I have shed in all my previous lives, they would fill the Pacific Ocean; if I gathered together all the teeth and hair I have lost, they would be higher than the Himalayas. And what have I got to show for all that? No wonder that Hindu and Buddhist sages have both focused much of their efforts on finding a way to get off this merry-go-round rather than to perpetuate it.
The second problem with this theory is the paucity of supporting evidence. What proof have I got that in a past life I was a medieval peasant, a Neanderthal hunter, a Tyrannosaurus rex, or an amoeba (if I really lived millions of lives, I must have been a dinosaur and an amoeba at some point, for humans have existed for only the last 2.5 million years)? Who vouches that in the future I will be reborn as a cyborg, an intergalactic explorer, or even a frog? Basing my life on this promise is a bit like selling my house in exchange for a post-dated cheque drawn on a bank above the clouds.
People who doubt that some kind of soul or spirit really survives their death therefore strive to leave behind something a bit more tangible. That ‘something tangible’ could take one of two forms: cultural or biological. I might leave behind a poem, say, or some of my precious genes. My life has meaning because people will still read my poem a hundred years from now, or because my kids and grandchildren will still be around. And what is the meaning of their lives? Well, that’s their problem, not mine. The meaning of life is thus a bit like playing with a live hand grenade. Once you pass it on to somebody else, you are safe.
