It’s rather like, if you think back in terms of animal evolution, an animal that’s grown an incredible carapace around it such as a tortoise—that’s a great survival strategy because nothing can get through it; or maybe like a poisonous fish that nothing will come close to, which therefore thrives by keeping away any challenges to what it is. In the case of an idea, if we think, “Here is an idea that is protected by holiness or sanctity,” what does it mean? Why should it be that it’s perfectly legitimate to support the Labour Party or the Conservative Party, Republicans or Democrats, this model of economics versus that, Macintosh instead of Windows, but to have an opinion about how the universe began, about who created the universe, no, that’s holy? What does that mean? Why do we ring-fence that for any other reason other than that we’ve just got used to doing so? There’s no other reason at all, it’s just one of those things that crept into being, and once that loop gets going, it’s very, very powerful. So we are used to not challenging religious ideas, but it’s very interesting how much of a furor Richard creates when he does it! Everybody gets absolutely frantic about it because you’re not allowed to say these things. Yet when you look at it rationally, there is no reason why those ideas shouldn’t be as open to debate as any other, except we have agreed somehow between us that they shouldn’t be.

There’s a very interesting book—I don’t know if anybody here’s read it—called Man on Earth, by an anthropologist who used to be at Cambridge, called John Reader, in which he describes the way that ... I’m going to back up a little bit and tell you about the whole book. It’s a series of studies of different cultures in the world that have developed within somewhat isolated circumstances, on islands or in a mountain valley or wherever, so it’s possible to treat them to a certain extent as a test-tube case. You see therefore exactly the degree to which their environment and their immediate circumstances have affected the way in which their culture has arisen. It’s a fascinating series of studies. The one I have in mind at the moment is the culture and economy of Bali, which is a small, very crowded island that subsists on rice. Now, rice is an incredibly efficient food and you can grow an awful lot in a relatively small space, but it’s hugely labour-intensive and requires a lot of very, very precise cooperation amongst the people there, particularly when you have a large population on a small island needing to bring its harvest in. People now looking at the way in which rice agriculture works in Bali are rather puzzled by it, because it is intensely religious. The society of Bali is such that religion permeates every single aspect of it and everybody in that culture is very, very carefully defined in terms of who they are, what their status is, and what their role in life is. It’s all defined by the church; they have very peculiar calendars and a very peculiar set of customs and rituals, which are precisely defined, and, oddly enough, they are fantastically good at being very, very productive with their rice harvest. In the seventies, people came in and noticed that the rice harvest was determined by the temple calendar. It seemed to be totally nonsensical, so they said, “Get rid of all this, we can help you make your rice harvest much, much more productive than even you’re, very successfully, doing at the moment. Use these pesticides, use this calendar, do this, that and the other.” So they started, and for two or three years the rice production went up enormously, but the whole predator/prey/pest balance went completely out of kilter. Very shortly the rice harvest plummeted again, and the Balinese said, “Screw it, we’re going back to the temple calendar!” and they reinstated what was there before and it all worked again absolutely perfectly. It’s all very well to say that basing the rice harvest on something as irrational and meaningless as a religion is stupid—they should be able to work it out more logically than that. They might just as well say to us “Your culture and society work on the basis of money and that’s a fiction, so why don’t you get rid of it and just cooperate with each other.” We know that’s not going to work!

So there is a sense in which we build meta-systems above ourselves to fill in the space that we previously populated with an entity that was supposed to be the intentional designer, the creator (even though there isn’t one) and because we—I don’t necessarily mean we in this room, but we as a species—design and create one and then allow ourselves to behave as if there was one, all sorts of things begin to happen that otherwise wouldn’t happen.

Let me try to illustrate what I mean. This is very speculative. I’m really going out on a limb here, because it’s something I know nothing about whatsoever, so think of this more as a thought experiment than a real explanation of something. I want to talk about feng shui, which is something I know little about, but there’s been a lot of talk about it recently in terms of figuring out how a building should be designed, built, situated, decorated, and so on. Apparently we need to think about the building being inhabited by dragons and look at it in terms of how a dragon would move around it. So, if a dragon wouldn’t be happy in the house, you have to put a red fishbowl here or a window there. This sounds like complete and utter nonsense, because anything involving dragons must be nonsense—there aren’t any dragons, so any theory based on how dragons behave is nonsense. What are these silly people doing, imagining that dragons can tell you how to build your house? Nevertheless, it occurs to me that if you disregard for a moment the explanation that’s actually offered for it, it may be there is something interesting going on that goes like this: we all know from buildings that we’ve lived in, worked in, been in, or stayed in, that some are more comfortable, more pleasant, and more agreeable to live in than others. We haven’t had a real way of quantifying this, but in this century we’ve had an awful lot of architects who thought they knew how to do it, so we’ve had the horrible idea of the house as a machine for living in, we’ve had Mies van der Rohe and others putting up glass stumps and strangely shaped things that are supposed to form some theory or other. It’s all carefully engineered, but nonetheless, their buildings are not actually very nice to live in. An awful lot of theory has been poured into this, but if you sit and work with an architect (and I’ve been through that stressful time, as I’m sure a lot of people have), then when you are trying to figure out how a room should work, you’re trying to integrate all kinds of things about lighting, about angles, about how people move and how people live—and an awful lot of other things you don’t know about that get left out. You don’t know what importance to attach to one thing or another; you’re trying, very consciously, to figure out something when you haven’t really got much of a clue, but there’s this theory and that theory, this bit of engineering practice and that bit of architectural practice; you don’t really know what to make of them. Compare that to somebody who tosses a cricket ball at you. You can sit and watch it and say, “It’s going at seventeen degrees,” start to work it out on paper, do some calculus, etc., and about a week after the ball’s whizzed past you, you may have figured out where it’s going to be and how to catch it. On the other hand, you can simply put your hand out and let the ball drop into it, because we have all kinds of faculties built into us, just below the conscious level, able to do all kinds of complex integrations of all kinds of complex phenomena, which therefore enable us to say, “Oh look, there’s a ball coming; catch it!”

What I’m suggesting is that feng shui and an awful lot of other things are precisely of that kind of problem. There are all sorts of things we know how to do, but don’t necessarily know what we do, we just do them. Go back to the issue of how you figure out how a room or a house should be designed, and instead of going through all the business of trying to work out the angles and trying to digest which genuine architectural principles you may want to take out of what may be a passing architectural fad, just ask yourself, “How would a dragon live here?” We are used to thinking in terms of organic creatures; an organic creature may consist of an enormous complexity of all sorts of different variables that are beyond our ability to resolve, but we know how organic creatures live. We’ve never seen a dragon, but we’ve all got an idea of what a dragon is like, so we can say, “Well, if a dragon went through here, he’d get stuck just here and a little bit cross over there because he couldn’t see that and he’d wave his tail and knock that vase over.” You figure out how the dragon’s going to be happy here, and lo and behold you’ve suddenly got a place that makes sense for other organic creatures, such as ourselves, to live in.

So, my argument is that as we become more and more scientifically literate, it’s worth remembering that the fictions with which we previously populated our world may have some function that it’s worth trying to understand and preserve the essential components of, rather than throwing out the baby with the bath water; because even though we may not accept the reasons given for them being here in the first place, it may well be that there are good practical reasons for them, or something like them, to be there. I suspect that as we move farther and farther into the field of digital or artificial life, we will find more and more unexpected properties begin to emerge out of what we see happening and that this is a precise parallel to the entities we create around ourselves to inform and shape our lives and enable us to work and live together. Therefore, I would argue that though there isn’t an actual God, there is an artificial God, and we should probably bear that in mind. That is my debating point, and you are now free to start hurling the chairs around!

Q. What is the fourth age of sand?

Let me back up for a minute and talk about the way we communicate. Traditionally, we have a bunch of different ways in which we communicate with each other. One way is one-to-one; we talk to each other, have a conversation. Another is one-to-many, which I’m doing at the moment, or someone could stand up and sing a song, or announce we’ve got to go to war. Then we have many-to-one communication; we have a pretty patchy, clunky, not-really-working version we call democracy, but in a more primitive state I would stand up and say, “Okay, we’re going to go to war,” and some may shout back, “No, we’re not!”—and then we have many-to-many communication in the argument that breaks out afterwards!

In this century (and the previous century) we modelled one-to-one communications in the telephone, which I assume we are all familiar with. We have one-to-many communication—boy, do we have an awful lot of that—broadcasting, publishing, journalism, etc. We get information poured at us from all over the place, and it’s completely indiscriminate as to where it might land. It’s curious, but we don’t have to go very far back in our history until we find that all the information that reached us was relevant to us and therefore anything that happened, any news, whether it was about something that’s actually happened to us, in the next house, or in the next village, within the boundary or within our horizon, it happened in our world, and if we reacted to it, the world reacted back. It was all relevant to us, so, for example, if somebody had a terrible accident, we could crowd round and really help. Nowadays, because of the plethora of one-to-many communication we have, if a plane crashes in India we may get terribly anxious about it, but our anxiety doesn’t have any impact. We’re not very well able to distinguish between a terrible emergency that’s happened to somebody a world away and something that’s happened to someone round the corner. We can’t really distinguish between them anymore which is why we get terribly upset by something that has happened to somebody in a soap opera that comes out of Hollywood and maybe less concerned when it’s happened to our sister. We’ve all become twisted and disconnected and it’s not surprising that we feel very stressed and alienated in the world because the world impacts on us but we don’t impact the world. Then there’s many-to-one; we have that, but not very well yet, and there’s not much of it about. Essentially, our democratic systems are a model of that, and though they’re not very good, they will improve dramatically.

But the fourth, the many-to-many, we didn’t have at all before the coming of the Internet, which, of course, runs on fiberoptics. It’s communication between us that forms the fourth age of sand. Take what I said earlier about the world not reacting to us when we react to it; I remember the first moment, a few years ago, at which I began to take the Internet seriously. It was a very, very silly thing. There was a guy, a computer research student at Carnegie Mellon, who liked to drink Dr Pepper Light. There was a drinks machine a couple of storeys away from him, where he used to regularly go and get his Dr Pepper, but the machine was often out of stock, so he had quite a few wasted journeys. Eventually he figured out, “Hang on, there’s a chip in there and I’m on a computer and there’s a network running around the building, so why don’t I just put the drinks machine on the network, then I can poll it from my terminal whenever I want, and tell if I’m going to have a wasted journey or not?” So he connected the machine to the local network, but the local net was part of the Internet—so suddenly anyone in the world could see what was happening with this drinks machine. Now, that may not be vital information but it turned out to be curiously fascinating; everyone started to know what was happening with the drinks machine. It began to develop, because the chip in the machine didn’t just say, “The slot which has Dr Pepper Light is empty,” but had all sorts of information; it said, “There are seven Cokes and three Diet Cokes, the temperature they are stored at is this and the last time they were loaded was that.” There was a lot of information in there, and there was one really fabulous piece of information: it turned out that if someone had put their fifty cents in and not pressed the button, i.e., if the machine was pregnant, then you could, from your computer terminal wherever you were in the world, log on to the drinks machine and drop that can! Somebody could be walking down the corridor when suddenly, bang!—there was a Coca-Cola can! What caused that? Well, obviously somebody five thousand miles away! Now that was a very, very silly but fascinating story, and what it said to me was that this was the first time we could reach back into the world. It may not be terribly important that from five thousand miles away you can reach into a university corridor and drop a Coca-Cola can, but it’s the first shot in the war of bringing to us a whole new way of communicating. So that, I think, is the fourth age of sand.
