Lex Fridman Podcast - #87 - Richard Dawkins: Evolution, Intelligence, Simulation, and Memes

The following is a conversation with Richard Dawkins,

an evolutionary biologist and author of The Selfish Gene,

The Blind Watchmaker, The God Delusion, The Magic of Reality,

and The Greatest Show of Earth and his latest All Growing God.

He is the originator and popularizer of a lot of fascinating ideas in evolutionary biology

and science in general, including, funny enough, the introduction of the word

meme in his 1976 book, The Selfish Gene, which, in the context of a gene centered view of evolution,

is an exceptionally powerful idea. He’s outspoken, bold, and often fearless in the

defense of science and reason, and in this way, is one of the most influential thinkers of our time.

This conversation was recorded before the outbreak of the pandemic.

For everyone feeling the medical, psychological, and financial burden of this crisis,

I’m sending love your way. Stay strong. We’re in this together. We’ll beat this thing.

buy bitcoin, and invest in the stock market with as little as one dollar.

Since Cash App allows you to send and receive money digitally, peer to peer,

security in all digital transactions is very important. Let me mention the PCI

data security standard that Cash App is compliant with. I’m a big fan of standards for safety and

security. PCI DSS is a good example of that, where a bunch of competitors got together and agreed

that there needs to be a global standard around the security of transactions.

Now we just need to do the same for autonomous vehicles and artificial intelligence systems in

general. So again, if you get Cash App from the App Store or Google Play and use the code LEX

around the world. And now, here’s my conversation with Richard Dawkins.

Do you think there’s intelligent life out there in the universe?

Well, if we accept that there’s intelligent life here and we accept that the number of planets in

the universe is gigantic, I mean, 10 to the 22 stars has been estimated, it seems to me highly

likely that there is not only life in the universe elsewhere, but also intelligent life. If you deny

that, then you’re committed to the view that the things that happened on this planet are

staggeringly improbable, I mean, ludicrously off the charts improbable. And I don’t think it’s that

improbable. Certainly the origin of life itself, there are really two steps, the origin of life,

which is probably fairly improbable, and then the subsequent evolution to intelligent life,

which is also fairly improbable. So the juxtaposition of those two, you could say,

is pretty improbable, but not 10 to the 22 improbable. It’s an interesting question,

maybe you’re coming on to it, how we would recognize intelligence from outer space if we

encountered it. The most likely way we would come across them would be by radio. It’s highly

unlikely they’d ever visit us. But it’s not that unlikely that we would pick up radio signals,

and then we would have to have some means of deciding that it was intelligent.

People involved in the SETI program discuss how they would do it, and things like prime numbers

would be an obvious way for them to broadcast, to say, we are intelligent, we are here.

I suspect it probably would be obvious, actually.

Well, that’s interesting, prime numbers, so the mathematical patterns, it’s an open question

whether mathematics is the same for us as it would be for aliens. I suppose we could assume

that ultimately, if we’re governed by the same laws of physics, then we should be governed by

the same laws of mathematics.

I think so. I suspect that they will have Pythagoras theorem, etc. I don’t think their

mathematics will be that different.

Do you think evolution would also be a force on the alien planets as well?

I stuck my neck out and said that if ever that we do discover life elsewhere, it will be Darwinian

life, in the sense that it will work by some kind of natural selection, the nonrandom survival of

randomly generated codes. It doesn’t mean that the genetic, it would have to have some kind of

genetics, but it doesn’t have to be DNA genetics, probably wouldn’t be actually.

But I think it would have to be Darwinian, yes.

So some kind of selection process.

Yes, in the general sense, it would be Darwinian.

So let me ask kind of an artificial intelligence engineering question. So you’ve been an

outspoken critic of, I guess, what could be called intelligent design, which is an attempt

to describe the creation of a human mind and body by some religious folks, religious folks

used to describe. So broadly speaking, evolution is, as far as I know, again, you can correct me,

is the only scientific theory we have for the development of intelligent life. Like there’s no

alternative theory, as far as I understand.

None has ever been suggested, and I suspect it never will be.

Well, of course, whenever somebody says that, a hundred years later.

I know. It’s a risk.

It’s a risk.

It’s a risk. But what a bet. I mean, I’m pretty confident.

But it would look, sorry, yes, it would probably look very similar, but it’s almost like Einstein

general relativity versus Newtonian physics. It’ll be maybe an alteration of the theory or

something like that, but it won’t be fundamentally different. But okay.

So now for the past 70 years, even before the AI community has been trying to engineer

intelligence, in a sense, to do what intelligent design says, you know, was done here on earth.

What’s your intuition? Do you think it’s possible to build intelligence, to build computers that

are intelligent, or do we need to do something like the evolutionary process? Like there’s

no shortcuts here.

That’s an interesting question. I’m committed to the belief that is ultimately possible

because I think there’s nothing nonphysical in our brains. I think our brains work by

the laws of physics. And so it must, in principle, it’d be possible to replicate that.

In practice, though, it might be very difficult. And as you suggest, it may be the only way

to do it is by something like an evolutionary process. I’d be surprised. I suspect that

it will come, but it’s certainly been slower in coming than some of the early pioneers

thought it would be.

Yeah. But in your sense, is the evolutionary process efficient? So you can see it as exceptionally

wasteful in one perspective, but at the same time, maybe that is the only path.

It’s a paradox, isn’t it? I mean, on the one side, it is deplorably wasteful. It’s

fundamentally based on waste. On the other hand, it does produce magnificent results.

I mean, the design of a soaring bird, an albatross, a vulture, an eagle, is superb. An engineer

would be proud to have done it. On the other hand, an engineer would not be proud to have

done some of the other things that evolution has served up. Some of the sort of botched

jobs that you can easily understand because of their historical origins, but they don’t

look well designed.

Do you have examples of bad design?

My favorite example is the recurrent laryngeal nerve. I’ve used this many times. This is

a nerve. It’s one of the cranial nerves, which goes from the brain, and the end organ is

that it supplies is the voice box, the larynx. But it doesn’t go straight to the larynx.

It goes right down into the chest and then loops around an artery in the chest and then

comes straight back up again to the larynx. And I’ve assisted in the dissection of a

giraffe’s neck, which happened to have died in a zoo. And we saw the recurrent laryngeal

nerve whizzing straight past the larynx, within an inch of the larynx, down into the chest,

and then back up again, which is a detour of many feet. Very, very inefficient.

The reason is historical. The ancestors are fish ancestors, the ancestors of all mammals

and fish. The most direct pathway of that, of the equivalent of that nerve, there wasn’t

a larynx in those days, but it innervated part of the gills. The most direct pathway

was behind that artery. And then when the mammal, when the tetrapods, when the land

vertebrae started evolving, and then the neck started to stretch, the marginal cost of changing

the embryological design to jump that nerve over the artery was too great. Or rather,

each step of the way was a very small cost, but the cost of actually jumping it over would have

been very large. As the neck lengthened, it was a negligible change to just increase the length of

the detour a tiny bit, a tiny bit, a tiny bit, each millimeter at a time, didn’t make any difference.

But finally, when you get to a giraffe, it’s a huge detour and no doubt is very inefficient.

Now that’s bad design. Any engineer would reject that piece of design. It’s ridiculous.

And there are quite a number of examples, as you’d expect. It’s not surprising that we find

examples of that sort. In a way, what’s surprising is there aren’t more of them. In a way, what’s

surprising is that the design of living things is so good. So natural selection manages to achieve

excellent results, partly by tinkering, partly by coming along and cleaning up initial mistakes and,

as it were, making the best of a bad job. That’s really interesting. I mean, it is surprising and

beautiful and it’s a mystery from an engineering perspective that so many things are well designed.

I suppose the thing we’re forgetting is how many generations have to die for that.

That’s the inefficiency of it. Yes, that’s the horrible wastefulness of it.

So yeah, we marvel at the final product, but yeah, the process is painful.

Elon Musk describes human beings as potentially what he calls the biological bootloader for

artificial intelligence or artificial general intelligence is used as the term. It’s kind of

like super intelligence. Do you see superhuman level intelligence as potentially the next step

in the evolutionary process? Yes, I think that if superhuman intelligence is to be found,

it will be artificial. I don’t have any hope that we ourselves, our brains will go on

getting larger in ordinary biological evolution. I think that’s probably come to an end. It is

the dominant trend or one of the dominant trends in our fossil history for the last two or three

million years. Brain size? Brain size, yes. So it’s been swelling rather dramatically over the last

two or three million years. That is unlikely to continue. The only way that happens is because

natural selection favors those individuals with the biggest brains and that’s not happening anymore.

Right. So in general, in humans, the selection pressures are not, I mean, are they active in

any form? Well, in order for them to be active, it would be necessary that the most, let’s call it

intelligence. Not that intelligence is simply correlated with brain size, but let’s talk about

intelligence. In order for that to evolve, it’s necessary that the most intelligent beings have

the most, individuals have the most children. And so intelligence may buy you money, it may buy you

worldly success, it may buy you a nice house and a nice car and things like that if you have a

successful career. It may buy you the admiration of your fellow people, but it doesn’t increase the

number of offspring that you have. It doesn’t increase your genetic legacy to the next generation.

On the other hand, artificial intelligence, I mean, computers and technology generally, is

is evolving by a non genetic means, by leaps and bounds, of course. And so what do you think,

I don’t know if you’re familiar, there’s a company called Neuralink, but there’s a general effort of

brain computer interfaces, which is to try to build a connection between the computer and the brain

to send signals both directions. And the long term dream there is to do exactly that, which is expand,

I guess, expand the size of the brain, expand the capabilities of the brain. Do you see this as

interesting? Do you see this as a promising possible technology? Or is the interface between

the computer and the brain, like the brain is this wet, messy thing that’s just impossible to

interface with? Well, of course, it’s interesting, whether it’s promising, I’m really not qualified

to say. What I do find puzzling is that the brain being as small as it is compared to a computer and

the individual components being as slow as they are compared to our electronic components,

it is astonishing what it can do. I mean, imagine building a computer that fits into the size of a

human skull. And with the equivalent of transistors or integrated circuits, which work as slowly as

neurons do. It’s something mysterious about that, something, something must be going on that we

don’t understand. So I have just talked to Roger Penrose, I’m not sure you’re familiar with his

work. And he also describes this kind of mystery in the mind, in the brain, that as he sees a

materialist, so there’s no sort of mystical thing going on. But there’s so much about the material

of the brain that we don’t understand. That might be quantum mechanical in nature and so on. So

there the idea is about consciousness. Do you have any, have you ever thought about, do you ever

think about ideas of consciousness or a little bit more about the mystery of intelligence and

consciousness that seems to pop up just like you’re saying from our brain? I agree with Roger

Penrose that there is a mystery there. I mean, he’s one of the world’s greatest physicists. I

can’t possibly argue with his… But nobody knows anything about consciousness. And in fact,

if we talk about religion and so on, the mystery of consciousness is so awe inspiring and we know

so little about it that the leap to sort of religious or mystical explanations is too easy

to make. I think that it’s just an act of cowardice to leap to religious explanations and

Roger doesn’t do that, of course. But I accept that there may be something that we don’t understand

about it. So correct me if I’m wrong, but in your book, Selfish Gene, the gene centered view of

evolution allows us to think of the physical organisms as just the medium through which the

software of our genetics and the ideas sort of propagate. So maybe can we start just with the

basics? What in this context does the word meme mean? It would mean the cultural equivalent of a

gene, cultural equivalent in the sense of that which plays the same role as the gene in the

transmission of culture and the transmission of ideas in the broadest sense. And it’s a

useful word if there’s something Darwinian going on. Obviously, culture is transmitted,

but is there anything Darwinian going on? And if there is, that means there has to be something

like a gene, which becomes more numerous or less numerous in the population.

So it can replicate?

It can replicate. Well, it clearly does replicate. There’s no question about that.

The question is, does it replicate in a sort of differential way in a Darwinian fashion? Could you

say that certain ideas propagate because they’re successful in the meme pool? In a sort of trivial

sense, you can. Would you wish to say, though, that in the same way as an animal body is modified,

adapted to serve as a machine for propagating genes, is it also a machine for propagating memes?

Could you actually say that something about the way a human is, is modified, adapted,

is modified, adapted for the function of meme propagation?

That’s such a fascinating possibility, if that’s true. That it’s not just about the genes which

seem somehow more comprehensible as these things of biology. The idea that culture or maybe ideas,

you can really broadly define it, operates under these mechanisms.

Even morphology, even anatomy does evolve by memetic means. I mean, things like hairstyles,

styles of makeup, circumcision, these things are actual changes in the body form which are

nongenetic and which get passed on from generation to generation or sideways like a virus in a

quasi genetic way.

But the moment you start drifting away from the physical, it becomes interesting because

the space of ideas, ideologies, political systems.

Of course, yes.

So what’s your sense? Are memes a metaphor more or are they really,

is there something fundamental, almost physical presence of memes?

Well, I think they’re a bit more than a metaphor. And I mentioned the physical

bodily characteristics which are a bit trivial in a way, but when things like the propagation

of religious ideas, both longitudinally down generations and transversely as in a sort of

epidemiology of ideas, when a charismatic preacher converts people, that resembles viral

transmission. Whereas the longitudinal transmission from grandparent to parent to child,

et cetera, is more like conventional genetic transmission.

That’s such a beautiful, especially in the modern day idea. Do you think about this

implication in social networks where the propagation of ideas, the viral propagation of ideas,

and has the new use of the word meme to describe?

Well, the internet, of course, provides extremely rapid method of transmission.

Before, when I first coined the word, the internet didn’t exist. And so I was thinking

that in terms of books, newspapers, broader radio, television, that kind of thing.

Now an idea can just leap around the world in all directions instantly. And so the internet

provides a step change in the facility of propagation of memes.

How does that make you feel? Isn’t it fascinating that sort of ideas, it’s like you have Galapagos

Islands or something, it’s the 70s, and the internet allowed all these species to just

like globalize. And in a matter of seconds, you can spread the message to millions of

people. And these ideas, these memes can breed, can evolve, can mutate. And there’s a selection,

and there’s like different, I guess, groups that have all like, there’s a dynamics that’s

fascinating here. Do you think, yes, basically, do you think your work in this direction,

while fundamentally was focused on life on Earth, do you think it should continue, like

to be taken further?

Well, I do think it would probably be a good idea to think in a Darwinian way about this

sort of thing. We conventionally think of the transmission of ideas from an evolutionary

context as being limited to, in our ancestors, people living in villages, living in small

bands where everybody knew each other, and ideas could propagate within the village,

and they might hop to a neighboring village, occasionally, and maybe even to a neighboring

continent eventually. And that was a slow process. Nowadays, villages are international.

I mean, you have people, it’s been called echo chambers, where people are in a sort

of internet village, where the other members of the village may be geographically distributed

all over the world, but they just happen to be interested in the same things, use the

same terminology, the same jargon, have the same enthusiasm. So, people like the Flat

Earth Society, they don’t all live in one place, they find each other, and they talk

the same language to each other, they talk the same nonsense to each other. And they,

so this is a kind of distributed version of the primitive idea of people living in villages

and propagating their ideas in a local way.

Is there Darwinist parallel here? So, is there evolutionary purpose of villages, or is that

just a…

I wouldn’t use a word like evolutionary purpose in that case, but villages will be something

that just emerged, that’s the way people happen to live.

And in just the same kind of way, the Flat Earth Society, societies of ideas emerge in

the same kind of way in this digital space.

Yes, yes.

Is there something interesting to say about the, I guess, from a perspective of Darwin,

could we fully interpret the dynamics of social interaction in these social networks? Or is

there some much more complicated thing need to be developed? Like, what’s your sense?

Well, a Darwinian selection idea would involve investigating which ideas spread and which

don’t. So, some ideas don’t have the ability to spread. I mean, the Flat Earth, Flat Earthism

is, there are a few people believe in it, but it’s not going to spread because it’s

obvious nonsense. But other ideas, even if they are wrong, can spread because they are

attractive in some sense.

So the spreading and the selection in the Darwinian context is, it just has to be attractive

in some sense. Like we don’t have to define, like it doesn’t have to be attractive in the

way that animals attract each other. It could be attractive in some other way.

Yes. All that matters is, all that is needed is that it should spread. And it doesn’t have

to be true to spread. In truth, there’s one criterion which might help an idea to spread.

But there are other criteria which might help it to spread. As you say, attraction in animals

is not necessarily valuable for survival. The famous peacock’s tail doesn’t help the

peacock to survive. It helps it to pass on its genes. Similarly, an idea which is actually

rubbish, but which people don’t know is rubbish and think is very attractive will spread in

the same way as a peacock’s gene spread.

It’s a small sidestep. I remember reading somewhere, I think recently, that in some

species of birds, sort of the idea that beauty may have its own purpose and the idea that

some birds, I’m being ineloquent here, but there’s some aspects of their feathers and

so on that serve no evolutionary purpose whatsoever. There’s somebody making an argument that there

are some things about beauty that animals do that may be its own purpose. Does that

ring a bell for you? Does that sound ridiculous?

I think it’s a rather distorted bell. Darwin, when he coined the phrase sexual selection,

didn’t feel the need to suggest that what was attractive to females, usually is males

attracting females, that what females found attractive had to be useful. He said it didn’t

have to be useful. It was enough that females found it attractive. And so it could be completely

useless, probably was completely useless in the conventional sense, but was not at all

useless in the sense of passing on, Darwin didn’t call them genes, but in the sense of

reproducing. Others, starting with Wallace, the co discoverer of natural selection, didn’t

like that idea and they wanted sexually selected characteristics like peacock’s tails to be

in some sense useful. It’s a bit of a stretch to think of a peacock’s tail as being useful,

but in the sense of survival, but others have run with that idea and have brought it up

to date. And so there are two schools of thought on sexual selection, which are still active

and about equally supported now. Those who follow Darwin in thinking that it’s just enough

to say it’s attractive and those who follow Wallace and say that it has to be in some

sense useful.

Do you fall into one category or the other?

No, I’m open minded. I think they both could be correct in different cases. I mean, they’ve

both been made sophisticated in a mathematical sense, more so than when Darwin and Wallace

first started talking about it.

I’m Russian, I romanticize things, so I prefer the former, where the beauty in itself is

a powerful attraction, is a powerful force in evolution. On religion, do you think there

will ever be a time in our future where almost nobody believes in God, or God is not a part

of the moral fabric of our society?

Yes, I do. I think it may happen after a very long time. It may take a long time for that

to happen.

So do you think ultimately for everybody on Earth, religion, other forms of doctrines,

ideas could do better job than what religion does?

Yes. I mean, following in truth, reason.

Well, truth is a funny, funny word. And reason too. There’s, yeah, it’s a difficult idea

now with truth on the internet, right, and fake news and so on. I suppose when you say

reason, you mean the very basic sort of inarguable conclusions of science versus which political

system is better.

Yes, yes. I mean, truth about the real world, which is ascertainable by, not just by the

more rigorous methods of science, but by just ordinary sensory observation.

So do you think there will ever be a time when we move past it? Like, I guess another

way to ask it, are we hopelessly, fundamentally tied to religion in the way our society functions?

Well, clearly all individuals are not hopelessly tied to it because many individuals don’t

believe. You could mean something like society needs religion in order to function properly,

something like that. And some people have suggested that.

What’s your intuition on that?

Well, I’ve read books on it and they’re persuasive. I don’t think they’re that persuasive though.

I mean, some people suggested that society needs a sort of figurehead, which can be a

non existent figurehead in order to function properly. I think there’s something rather

patronising about the idea that, well, you and I are intelligent enough not to believe

in God, but the plebs need it sort of thing. And I think that’s patronising. And I’d like

to think that that was not the right way to proceed.

But at the individual level, do you think there’s some value of spirituality? Sort of,

if I think sort of as a scientist, the amount of things we actually know about our universe

is a tiny, tiny, tiny percentage of what we could possibly know. So just from everything,

even the certainty we have about the laws of physics, it seems to be that there’s yet

a huge amount to discover. And therefore we’re sitting where 99.99% of things are just still

shrouded in mystery. Do you think there’s a role in a kind of spiritual view of that,

sort of a humbled spiritual view?

I think it’s right to be humble. I think it’s right to admit that there’s a lot we don’t

know, a lot we don’t understand, a lot that we still need to work on. We’re working on

it. What I don’t think is that it helps to invoke supernatural explanations. If our current

scientific explanations aren’t adequate to do the job, then we need better ones. We need

to work more. And of course, the history of science shows just that, that as science goes

on, problems get solved one after another, and the science advances as science gets better.

But to invoke a non scientific, non physical explanation is simply to lie down in a cowardly

way and say, we can’t solve it, so we’re going to invoke magic. Don’t let’s do that. Let’s

say we need better science. We need more science. It may be that the science will never do it.

It may be that we will never actually understand everything. And that’s okay, but let’s keep

working on it.

A challenging question there is, do you think science can lead us astray in terms of the

humbleness? So there’s some aspect of science, maybe it’s the aspect of scientists and not

science, but of sort of a mix of ego and confidence that can lead us astray in terms of discovering

the, you know, some of the big open questions about the universe.

I think that’s right. I mean, there are, there are arrogant people in any walk of life and

scientists are no exception to that. And so there are arrogant scientists who think we’ve

solved everything. Of course we haven’t. So humility is a proper stance for a scientist.

I mean, it’s a proper working stance because it encourages further work. But in a way to

resort to a supernatural explanation is a kind of arrogance because it’s saying, well,

we don’t understand it scientifically. Therefore the non scientific religious supernatural

explanation must be the right one. That’s arrogant. What is, what is humble is to say

we don’t know and we need to work further on it.

So maybe if I could psychoanalyze you for a second, you have at times been just slightly

frustrated with people who have supernat, you know, have a supernatural. Has that changed

over the years? Have you become like, how do people that kind of have a seek supernatural

explanations, how do you see those people as human beings as it’s like, do you see them

as dishonest? Do you see them as, um, sort of, uh, ignorant? Do you see them as, I don’t

know, is it like, how do you think of certainly not, not, not dishonest. And, and I mean,

obviously many of them are perfectly nice people. So I don’t, I don’t sort of despise

them in that sense. Um, I think it’s often a misunderstanding that, that, um, people

will jump from the admission that we don’t understand something. They will jump straight

to what they think of as an alternative explanation, which is the supernatural one, which is not

an alternative. It’s a non explanation. Um, instead of jumping to the conclusion that

science needs more work, that we need to actually get, do some better, better science. So, um,

I don’t have, I mean, personal antipathy towards such people. I just think they’re, they’re


So what about this really interesting space that I have trouble with? So religion I have

a better grasp on, but, um, there’s a large communities, like you said, Flat Earth community,

uh, that I’ve recently, because I’ve made a few jokes about it. I saw that there’s,

I’ve noticed that there’s people that take it quite seriously. So there’s this bigger

world of conspiracy theorists, which is a kind of, I mean, there’s elements of it that

are religious as well, but I think they’re also scientific. So the, the basic credo of

a conspiracy theorist is to question everything, which is also the credo of a good scientist,

I would say. So what do you make of this?

I mean, I think it’s probably too easy to say that by labeling something conspiracy,

you therefore dismiss it. I mean, occasionally conspiracies are right. And so we shouldn’t

dismiss conspiracy theories out of hand. We should examine them on their own merits. Flat

Earthism is obvious nonsense. We don’t have to examine that much further. Um, but, um,

I mean, there may be other conspiracy theories which are actually right.

So I’ve, you know, grew up in the Soviet Union. So I, I just, you know, uh, the space race

was very influential for me on both sides of the coin. Uh, you know, there’s a conspiracy

theory that we never went to the moon. Right. And it’s, uh, it’s like, I cannot understand

it and it’s very difficult to rigorously scientifically show one way or the other. It’s just, you

have to use some of the human intuition about who would have to lie, who would have to work

together. And it’s clear that very unlikely, uh, good behind that is my general intuition

that most people in this world are good. You know, in order to really put together some

conspiracy theories, there has to be a large number of people working together and essentially

being dishonest.

Yes, which is improbable. The sheer number who would have to be in on this conspiracy

and the sheer detail, the attention to detail they’d have had to have had and so on. I’d

also worry about the motive and why would anyone want to suggest that it didn’t happen?

What’s the, what’s the, why is it so hard to believe? I mean, the, the physics of it,

the mathematics of it, the, the idea of computing orbits and, and, and trajectories and things,

it, it all works mathematically. Why wouldn’t you believe it?

It’s a psychology question because there’s something really pleasant about, um, you know,

pointing out that the emperor has no clothes when everybody like, uh, you know, thinking

outside the box and coming up with the true answer where everybody else is diluted. There’s

something, I mean, I have that for science, right? You want to prove the entire scientific

community wrong. That’s the whole.

That’s, that’s, that’s right. And, and of course, historically, lone geniuses have come

out right sometimes, but often people with who think they’re a lone genius much more

often turn out not to. Um, so you have to judge each case on its merits. The mere fact

that you’re a maverick, the mere fact that you, you’re going against the current tide

doesn’t make you right. You’ve got to show you’re right by looking at the evidence.

So because you focus so much on, on religion and disassembled a lot of ideas there and

I just, I was wondering if, if you have ideas about conspiracy theory groups, because it’s

such a prevalent, even reaching into, uh, presidential politics and so on. It seems

like it’s a very large communities that believe different kinds of conspiracy theories. Is

there some connection there to your thinking on religion? And it is curious. It’s a matter.

It’s an obvious difficult thing. Uh, I don’t understand why people believe things that

are clearly nonsense, like, well, flat earth and also the conspiracy about not landing

on the moon or, um, that, um, the, that the United States engineered 9 11 that, that kind

of thing. Um, so it’s not clearly nonsense. It’s extremely unlikely. Okay. It’s extremely

unlikely that religion is a bit different because it’s passed down from generation to

generation. So many of the people who are religious, uh, got it from their parents who

got it from their parents who got it from their parents and childhood indoctrination

is a very powerful force. But these things like the nine 11 conspiracy theory, the, um,

Kennedy assassination conspiracy theory, the man on the moon conspiracy theory, these are

not childhood indoctrination. These are, um, presumably dreamed up by somebody who then

tells somebody else who then wants to believe it. And I don’t know why people are so eager

to fall in line with some, just some person that they happen to read or meet who spins

some yarn. I can kind of understand why they believe what their parents and teachers told

them when they were very tiny and not capable of critical thinking for themselves. So I

sort of get why the great religions of the world like Catholicism and Islam go on persisting.

It’s because of childhood indoctrination, but that’s not true of flat earthism and sure

enough flat earthism is a very minority cult way larger than I ever realized. Well, yes,

I know, but so that’s a really clean idea and you’ve articulated that in your new book

and then, and I’ll go on God and in God, the illusion is the early indoctrination. That’s

really interesting that you can get away with a lot of out there ideas in terms of religious

texts. If, um, the age at which you convey those ideas at first is a young age. So indoctrination

is sort of an essential element of propagation of religion. So let me ask on the morality

side in the books that I mentioned, God, delusion, and I’ll go on God. You described that human

beings don’t need religion to be moral. So from an engineering perspective, we want to

engineer morality into AI systems. So in general, where do you think morals come from in humans?

A very complicated and interesting question. It’s clear to me that the moral standards,

the moral values of our civilization changes as the decades go by, certainly as the centuries

go by, even as the decades go by. And we in the 21st century are quite clearly labeled

21st century people in terms of our moral values. There’s a spread. I mean, some of

us are a little bit more ruthless, some of us more conservative, some of us more liberal

and so on. But we all subscribe to pretty much the same views when you compare us with

say 18th century, 17th century people, even 19th century, 20th century people. So we’re

much less racist, we’re much less sexist and so on than we used to be. Some people are

still racist and some are still sexist, but the spread has shifted. The Gaussian distribution

has moved and moves steadily as the centuries go by. And that is the most powerful influence

I can see on our moral values. And that doesn’t have anything to do with religion. I mean,

the religion, sorry, the morals of the Old Testament are Bronze Age models. They’re deplorable

and they are to be understood in terms of the people in the desert who made them up

at the time. And so human sacrifice, an eye for an eye, a tooth for a tooth, petty revenge,

killing people for breaking the Sabbath, all that kind of thing, inconceivable now.

So at some point religious texts may have in part reflected that Gaussian distribution

at that time.

I’m sure they did. I’m sure they always reflect that, yes.

And then now, but the sort of almost like the meme, as you describe it, of ideas moves

much faster than religious texts do, than new religions.

Yes. So basing your morals on religious texts, which were written millennia ago, is not a

great way to proceed. I think that’s pretty clear. So not only should we not get our morals

from such texts, but we don’t. We quite clearly don’t. If we did, then we’d be discriminating

against women and we’d be racist, we’d be killing homosexuals and so on. So we don’t

and we shouldn’t. Now, of course, it’s possible to use your 21st century standards of morality

and you can look at the Bible and you can cherry pick particular verses which conform

to our modern morality, and you’ll find that Jesus says some pretty nice things, which

is great. But you’re using your 21st century morality to decide which verses to pick, which

verses to reject. And so why not cut out the middleman of the Bible and go straight to

the 21st century morality, which is where that comes from. It’s a much more complicated

question. Why is it that morality, moral values change as the centuries go by? They undoubtedly

do. And it’s a very interesting question to ask why. It’s another example of cultural

evolution, just as technology progresses, so moral values progress for probably very

different reasons.

But it’s interesting if the direction in which that progress is happening has some evolutionary

value or if it’s merely a drift that can go into any direction.

I’m not sure it’s any direction and I’m not sure it’s evolutionarily valuable. What it

is is progressive in the sense that each step is a step in the same direction as the previous

step. So it becomes more gentle, more decent by modern standards, more liberal, less violent.

But more decent, I think you’re using terms and interpreting everything in the context

of the 21st century because Genghis Khan would probably say that this is not more decent

because we’re now, you know, there’s a lot of weak members of society that we’re not


Yes. I was careful to say by the standards of the 21st century, by our standards, if

we with hindsight look back at history, what we see is a trend in the direction towards

us, towards our present, our present value system.

For us, we see progress, but it’s an open question whether that won’t, you know, I don’t

see necessarily why we can never return to Genghis Khan times.

We could. I suspect we won’t. But if you look at the history of moral values over the centuries,

it is in a progressive, I use the word progressive not in a value judgment sense, in the sense

of a transitive sense. Each step is the same, is the same direction as the previous step.

So things like we don’t derive entertainment from torturing cats. We don’t derive entertainment

from like the Romans did in the Colosseum from that state.

Or rather we suppress the desire to get, I mean, to have play. It’s probably in us somewhere.

So there’s a bunch of parts of our brain, one that probably, you know, limbic system

that wants certain pleasures. And that’s I don’t, I mean, I wouldn’t have said that,

but you’re at liberty to think that you like, well, no, there’s a, there’s a Dan Carlin

of hardcore history. There’s a really nice explanation of how we’ve enjoyed watching

the torture of people, the fighting of people, just to torture the suffering of people throughout

history as entertainment until quite recently. And now everything we do with sports, we’re

kind of channeling that feeling into something else. I mean, there, there is some dark aspects

of human nature that are underneath everything. And I do hope this like higher level software

we’ve built will keep us at bay. I’m also Jewish and have history with the Soviet Union

and the Holocaust. And I clearly remember that some of the darker aspects of human nature

creeped up there.

They do. There have been, there have been steps backwards admittedly, and the Holocaust

is an obvious one. But if you take a broad view of history, it’s the same direction.

So Pamela McCordick in Machines Who Think has written that AI began with an ancient

wish to forge the gods. Do you see, it’s a poetic description I suppose, but do you see

a connection between our civilizations, historic desire to create gods, to create religions

and our modern desire to create technology and intelligent technology?

I suppose there’s a link between an ancient desire to explain away mystery and science,

but intelligence, artificial intelligence, creating gods, creating new gods. And I forget,

I read somewhere a somewhat facetious paper which said that we have a new god is called

Google and we pray to it and we worship it and we ask its advice like an Oracle and so

on. That’s fun.

You don’t see that, you see that as a fun statement, a facetious statement. You don’t

see that as a kind of truth of us creating things that are more powerful than ourselves

and natural.

It has a kind of poetic resonance to it, which I get, but I wouldn’t, I wouldn’t have bothered

to make the point myself, put it that way.

All right. So you don’t think AI will become our new god, a new religion, a new gods like


Well, yes. I mean, I can see that the future of intelligent machines or indeed intelligent

aliens from outer space might yield beings that we would regard as gods in the sense

that they are so superior to us that we might as well worship them. That’s highly plausible,

I think. But I see a very fundamental distinction between a god who is simply defined as something

very, very powerful and intelligent on the one hand and a god who doesn’t need explaining

by a progressive step by step process like evolution or like engineering design. So suppose

we did meet an alien from outer space who was marvelously, magnificently more intelligent

than us and we would sort of worship it for that reason. Nevertheless, it would not be

a god in the very important sense that it did not just happen to be there like god is

supposed to. It must have come about by a gradual step by step incremental progressive

process, presumably like Darwinian evolution. There’s all the difference in the world between

those two. Intelligence, design comes into the universe late as a product of a progressive

evolutionary process or progressive engineering design process.

So most of the work is done through this slow moving progress.


Yeah. Yeah. But there’s still this desire to get answers to the why question that if

the world is a simulation, if we’re living in a simulation, that there’s a programmer

like creature that we can ask questions of.

Well, let’s pursue the idea that we’re living in a simulation, which is not totally ridiculous,

by the way.

There we go.

Then you still need to explain the programmer. The programmer had to come into existence

by some… Even if we’re in a simulation, the programmer must have evolved. Or if he’s

in a sort of…

Or she.

If she’s in a meta simulation, then the meta program must have evolved by a gradual process.

You can’t escape that. Fundamentally, you’ve got to come back to a gradual incremental

process of explanation to start with.

There’s no shortcuts in this world.

No, exactly.

But maybe to linger on that point about the simulation, do you think it’s an interesting

thing? Basically, you talk to… Bored the heck out of everybody asking this question,

but whether you live in a simulation, do you think… First, do you think we live in a

simulation? Second, do you think it’s an interesting thought experiment?

It’s certainly an interesting thought experiment. I first met it in a science fiction novel

by Daniel Galloy called Counterfeit World, in which it’s all about… I mean, our heroes

are running a gigantic computer which simulates the world, and something goes wrong, and so

one of them has to go down into the simulated world in order to fix it. And then the denouement

of the thing, the climax to the novel, is that they discover that they themselves are

in another simulation at a higher level. So I was intrigued by this, and I love others

of Daniel Galloy’s science fiction novels. Then it was revived seriously by Nick Bostrom…

Bostrom talking to him in an hour.

And he goes further, not just treat it as a science fiction speculation, he actually

thinks it’s positively likely. I mean, he thinks it’s very likely, actually.

He makes a probabilistic argument, which you can use to come up with very interesting conclusions

about the nature of this universe.

I mean, he thinks that we’re in a simulation done by, so to speak, our descendants of the

future. But it’s still a product of evolution. It’s still ultimately going to be a product

of evolution, even though the super intelligent people of the future have created our world,

and you and I are just a simulation, and this table is a simulation and so on. I don’t actually

in my heart of hearts believe it, but I like his argument.

Well, so the interesting thing is that I agree with you, but the interesting thing to me,

if I were to say, if we’re living in a simulation, that in that simulation, to make it work,

you still have to do everything gradually, just like you said. That even though it’s

programmed, I don’t think there could be miracles.

Well, no, I mean, the programmer, the higher, the upper ones have to have evolved gradually.

However, the simulation they create could be instantaneous. I mean, they could be switched

on and we come into the world with fabricated memories.

True, but what I’m trying to convey, so you’re saying the broader statement, but I’m saying

from an engineering perspective, both the programmer has to be slowly evolved and the

simulation because it’s like, from an engineering perspective.

Oh yeah, it takes a long time to write a program.

No, like just, I don’t think you can create the universe in a snap. I think you have to

grow it.

Okay. Well, that’s a good point. That’s an arguable point. By the way, I have thought

about using the Nick Bostrom idea to solve the riddle of how you were talking. We were

talking earlier about why the human brain can achieve so much. I thought of this when

my then 100 year old mother was marveling at what I could do with a smartphone and I

could call, look up anything in the encyclopedia, I could play her music that she liked and

so on. She said, but it’s all in that tiny little phone. No, it’s out there. It’s in

the cloud. And maybe most of what we do is in a cloud. So maybe if we are a simulation,

even all the power that we think is in our skull, it actually may be like the power that

we think is in the iPhone. But is that actually out there in an interface to something else?

I mean, that’s what, including Roger Penrose with panpsychism, that consciousness is somehow

a fundamental part of physics, that it doesn’t have to actually all reside inside. But Roger

thinks it does reside in the skull, whereas I’m suggesting that it doesn’t, that there’s

a cloud.

That’d be a fascinating notion. On a small tangent, are you familiar with the work of

Donald Hoffman, I guess? Maybe not saying his name correctly, but just forget the name,

the idea that there’s a difference between reality and perception. So like we biological

organisms perceive the world in order for the natural selection process to be able to

survive and so on. But that doesn’t mean that our perception actually reflects the fundamental

reality, the physical reality underneath.

Well, I do think that although it reflects the fundamental reality, I do believe there

is a fundamental reality, I do think that our perception is constructive in the sense

that we construct in our minds a model of what we’re seeing. And so this is really the

view of people who work on visual illusions, like Richard Gregory, who point out that things

like a Necker cube, which flip from a two dimensional picture of a cube on a sheet of

paper, we see it as a three dimensional cube, and it flips from one orientation to another

at regular intervals. What’s going on is that the brain is constructing a cube, but the

sense data are compatible with two alternative cubes. And so rather than stick with one of

them, it alternates between them. I think that’s just a model for what we do all the

time when we see a table, when we see a person, when we see anything, we’re using the sense

data to construct or make use of a perhaps previously constructed model. I noticed this

when I meet somebody who actually is, say, a friend of mine, but until I kind of realized

that it is him, he looks different. And then when I finally clock that it’s him, his features

switch like a Necker cube into the familiar form. As it were, I’ve taken his face out

of the filing cabinet inside and grafted it onto or used the sense data to invoke it.

Yeah, we do some kind of miraculous compression on this whole thing to be able to filter out

most of the sense data and make sense of it. That’s just a magical thing that we do. So

you’ve written several, many amazing books, but let me ask, what books, technical or fiction

or philosophical, had a big impact on your own life? What books would you recommend people

consider reading in their own intellectual journey?

Darwin, of course. The original. I’m actually ashamed to say I’ve never read Darwin. He’s

astonishingly prescient because considering he was writing in the middle of the 19th century,

Michael Gieselin said he’s working 100 years ahead of his time. Everything except genetics

is amazingly right and amazingly far ahead of his time. And of course, you need to read

the updatings that have happened since his time as well. I mean, he would be astonished

by, well, let alone Watson and Crick, of course, but he’d be astonished by Mendelian genetics

as well.

Yeah, it’d be fascinating to see what he thought about DNA, what he would think about DNA.

I mean, yes, it would. Because in many ways, it clears up what appeared in his time to

be a riddle. The digital nature of genetics clears up what was a problem, what was a big

problem. Gosh, there’s so much that I could think of. I can’t really…

Is there something outside sort of more fiction? When you think young, was there books that

just kind of outside of kind of the realm of science or religion that just kind of sparked

your journey?

Yes. Well, actually, I suppose I could say that I’ve learned some science from science

fiction. I mentioned Daniel Galloy, and that’s one example, but another of his novels called

Dark Universe, which is not terribly well known, but it’s a very, very nice science

fiction story. It’s about a world of perpetual darkness. And we’re not told at the beginning

of the book why these people are in darkness. They stumble around in some kind of underground

world of caverns and passages, using echolocation like bats and whales to get around. And they’ve

adapted, presumably by Darwinian means, to survive in perpetual total darkness. But what’s

interesting is that their mythology, their religion has echoes of Christianity, but it’s

based on light. And so there’s been a fall from a paradise world that once existed where

light reigns supreme. And because of the sin of mankind, light banished them. So they no

longer are in light’s presence, but light survives in the form of mythology and in the

form of sayings like, there’s a great light almighty. Oh, for light’s sake, don’t do that.

And I hear what you mean rather than I see what you mean.

So some of the same religious elements are present in this other totally kind of absurd

different form.

Yes. And so it’s a wonderful, I wouldn’t call it satire, because it’s too good natured

for that. I mean, a wonderful parable about Christianity and the doctrine, the theological

doctrine of the fall. So I find that kind of science fiction immensely stimulating.

Fred Hoyle’s The Black Cloud. Oh, by the way, anything by Arthur C. Clarke I find very wonderful

too. Fred Hoyle’s The Black Cloud, his first science fiction novel, where he, well, I learned

a lot of science from that. It suffers from an obnoxious hero, unfortunately, but apart

from that, you learn a lot of science from it. Another of his novels, A for Andromeda,

which by the way, the theme of that is taken up by Carl Sagan’s science fiction novel,

another wonderful writer, Carl Sagan, Contact, where the idea is, again, we will not be visited

from outer space by physical bodies. We will be visited possibly, we might be visited by

radio, but the radio signals could manipulate us and actually have a concrete influence

on the world if they make us or persuade us to build a computer, which runs their software.

So that they can then transmit their software by radio, and then the computer takes over

the world. And this is the same theme in both Hoyle’s book and Sagan’s book, I presume.

I don’t know whether Sagan knew about Hoyle’s book, probably did. But it’s a clever idea

that we will never be invaded by physical bodies. The War of the Worlds of H.G. Wells

will never happen. But we could be invaded by radio signals, code, coded information,

which is sort of like DNA. And we are, I call them, we are survival machines of our DNA.

So it has great resonance for me, because I think of us, I think of bodies, physical

bodies, biological bodies, as being manipulated by coded information, DNA, which has come

down through generations.

And in the space of memes, it doesn’t have to be physical, it can be transmitted through

the space of information. That’s a fascinating possibility, that from outer space we can

be infiltrated by other memes, by other ideas, and thereby controlled in that way. Let me

ask the last, the silliest, or maybe the most important question. What is the meaning of

life? What gives your life fulfillment, purpose, happiness, meaning?

From a scientific point of view, the meaning of life is the propagation of DNA, but that’s

not what I feel. That’s not the meaning of my life. So the meaning of my life is something

which is probably different from yours and different from other people’s, but we each

make our own meaning. So we set up goals, we want to achieve, we want to write a book,

we want to do whatever it is we do, write a quartet, we want to win a football match.

And these are short term goals, well, maybe even quite long term goals, which are set

up by our brains, which have goal seeking machinery built into them. But what we feel,

we don’t feel motivated by the desire to pass on our DNA, mostly. We have other goals which

can be very moving, very important. They could even be called as called spiritual in some

cases. We want to understand the riddle of the universe, we want to understand consciousness,

we want to understand how the brain works. These are all noble goals. Some of them can

be noble goals anyway. And they are a far cry from the fundamental biological goal,

which is the propagation of DNA. But the machinery that enables us to set up these higher level

goals is originally programmed into us by natural selection of DNA.

The propagation of DNA. But what do you make of this unfortunate fact that we are mortal?

Do you ponder your mortality? Does it make you sad?

I ponder it. It would, it makes me sad that I shall have to leave and not see what’s going

to happen next. If there’s something frightening about mortality, apart from sort of missing,

as I said, something more deeply, darkly frightening, it’s the idea of eternity. But eternity is

only frightening if you’re there. Eternity before we were born, billions of years before

we were born, and we were effectively dead before we were born. As I think it was Mark

Twain said, I was dead for billions of years before I was born and never suffered the smallest

inconvenience. That’s how it’s going to be after we leave. So I think of it as really,

mortality is a frightening prospect. And so the best way to spend it is under a general

anesthetic, which is what it’ll be.

Beautifully put. Richard, it is a huge honor to meet you, to talk to you. Thank you so

much for your time.

And now let me leave you with some words of wisdom from Richard Dawkins.

We are going to die. And that makes us the lucky ones. Most people are never going to

die because they are never going to be born. The potential people who could have been here

in my place but who will in fact never see the light of day outnumber the sand grains

of Arabia. Certainly, those unborn ghosts include greater poets than Keats, scientists

greater than Newton. We know this because the set of possible people allowed by our

DNA so massively exceeds the set of actual people. In the teeth of these stupefying odds,

it is you and I, in our ordinariness, that are here. We privileged few who won the lottery

of birth against all odds. How dare we whine at our inevitable return to that prior state

from which the vast majority have never stirred.

Thank you for listening and hope to see you next time.
