You've been described as 'an evangelical
atheist'. Is that a title you'd be happy to adopt, or is it a
label you dislike?
It sounds too negative to me, because
atheism, after all, is a negative thing. I occasionally feel a
bit evangelical when I notice what I think of as the evils of
theism, where people have such strong beliefs that they feel that
they are entitled to impose them, or their consequences on other
people.
The other thing that does make me feel
a bit evangelical is that I'd say I have a very positive, I'd
almost say poetic, vision of the universe from a scientific point
of view. I feel people are missing something if they content themselves
with what I think of as an outdated, medieval view of the world,
when they could be latching on to something much more exciting.
Awe and wonder are things which religious
people undoubtedly feel, but I get a bit irritated when they imply
they have a monopoly of them. I think I can feel wonder at least
as well as the next man, and I am stimulated to do so by contemplating
the huge size and age of the universe, the immense range of sizes
of things, from fundamental particles to galaxies, and the awe-inspiring
consequences of evolution, starting from simple beginnings and
working up to prodigies of complexity like ourselves.
That, I think, ought to inspire in people
a kind of poetic sense of wonder - it does in me, and I try to
convey it to other people. I find the alternative, religious vision
smaller, less imaginative and less exciting by comparison.
Was there ever a time when you believed
in God?
As a child I did. I had a normal Anglican
upbringing and, yes, I believed what I was told.
What kind of a god was he?
Pretty much Anglican: creator of the world,
looks after it, knows what is going on in everybody's mind. Occasionally
intervenes in the world; makes you survive death.
And then, at 16, you began to question
this?
I suppose, by then, of all the classical
arguments for the existence of God, only the argument from design
seemed to me to carry any weight, and I finally toppled that in
my mind when I learned about evolution.
In The Selfish Gene, you say that the
theory of evolution is about as open to doubt as the theory that
the Earth goes around the Sun. Can you elaborate?
People sometimes try to score debating
points by saying, "Evolution is only a theory." That
is correct, but it's important to understand what that means.
It is also only a theory that the world goes round the Sun - it's
just a theory for which there is an immense amount of evidence.
There are many scientific theories that
are in doubt. Even within evolution, there is some room for controversy.
But that we are cousins of apes and jackals and starfish, let's
say, that is a fact in the ordinary sense of the word.
How do you believe life itself began?
The origin of life has got to be something
self-replicating. We don't know what it was, but whatever it was,
it was self-replicating.
That is the big leap for evolutionary
theory, isn't it? How do we get that first self-replicating system?
It is a big leap; I don't think it's the
biggest. The step from a molecule to a man seems to me to be rather
bigger.
If you look at the sorts of self-replicating
systems that chemists have produced in the test-tube, the difference
is relatively trivial. You have some sort of molecule much the
same as any of the others that chemists are fooling around with,
and they do some little things and they've got a self-replicating
molecule. It looks much the same as any other: it's no bigger,
it's no more fancy, it just has a particular shape.
What do you mean exactly by 'self-replicating'?
It has to grow and then split, so that
it produces daughter units like itself. You can make small, pretty
ordinary organic molecules which just have the property that something
about their shape forms a mould or template into which the constituent
sub-molecules slot in just such a way that they produce a new
composite molecule just like the original.
So, then you've got two and each of those
forms a template and then you've got four and then eight, and
then 16, and so you get the exponential increase you require.
You even get mutations, and therefore
two different kinds of self-replicating molecule in a state of
primitive Darwinian competition.
You say in The Blind Watchmaker that
you don't need to postulate the idea of God to explain how the
world is. What do you mean by that?
The whole scientific enterprise is aimed
at explaining the world in terms of simple principles. We live
in a world which is breathtakingly complicated, and we have a
scientific theory - we have several - which enables us to see
how that world could have come into being from very simple beginnings.
That's what I call understanding. If I
want to understand how a machine works, I want an explanation
in terms of sub-units and even smaller sub-units, and finally
I would get down to fundamental particles. That's the kind of
explanation which science aspires to give and is well on the way
to giving.
That is a very reductionist approach.
That is precisely what it is; that is
what's good about it. Reductionist explanations are true explanations.
You really feel you've understood how
a motor car works if you've been told how each of its bits work
and how the bits move together to make the car work. Then you
feel you've really got somewhere. But if somebody tried to explain
the car in terms of - well, Julian Huxley satirised it as explaining
a railway train by force locomotive - you would feel you had understood
absolutely nothing.
Are there not other levels of explanation?
There's the classic story of the man on the cliff who sees a light,
and analyzes it in terms of its frequency, intensity and so on.
But the point is, the light is a message in morse and it's saying
the cliff is about to collapse.
Well, that anecdote certainly makes sense;
but it doesn't stand for anything. The message is presumably coming
from another human, and of course, messages from other humans
are very complicated things; but they, too, can be explained.
The explanation in terms of the wavelength of light is not the
only reductive explanation.
What you seem to say in The Blind Watchmaker
is that because we don't need to postulate the idea of God, therefore
we can reject it.
Yes. I don't think God is an explanation
at all. It's simply redescribing the problem.
We are trying to understand how we have
got a complicated world, and we have an explanation in terms of
a slightly simpler world, and we explain that in terms of a slightly
simpler world and it all hangs together down to an ultimately
simple world.
Now, God is not an explanation of that
kind. God himself cannot be simple if he has power to do all the
things he is supposed to do.
That assumes that the only good explanation
is a reductionist one.
I'm not sure if it's just an assumption.
The very least I can say is that it's the only kind of explanation
I find satisfying. I wish I could persuade you that it's the only
kind of explanation that is satisfying.
I think I can with respect to Huxley's
force locomotive. If you watch a railway engine and you ask me
how it works, there's a hierarchy of reductive explanations. You
begin by explaining it in terms of a boiler and a piston, and
then you go down to the level of classical physics and you talk
about what pressure means in terms of molecules. Then you go down
to quantum physics, and the whole thing hangs together as an explanation
of big and complicated things in terms of small and simple things.
That's satisfying. Force locomotive is
not satisfying to me, and I don't believe it's satisfying to you.
No. But if I asked, "Why is that
kettle boiling?" we could talk in terms of the processes
or we could consider another meaning of 'why', which is to do
with purpose. The reason it's boiling is because your wife Lalla
put the kettle on to make a cup of tea.
Yes. I'm not impressed, because the explanation
that somebody switched on the kettle and had a purpose in doing
so simply is not a different kind of explanation. It's just a
more complicated problem that we now have to solve.
We now have to go and look at her brain
and ask what it is that made her want to switch the kettle on.
And that takes us back to the workings of her brain, to why she
has a brain in the first place, which gets us back to evolution.
There's a whole cascade of similar explanations.
Aren't you explaining your wife away?
Who is she?
Well, that's a more profound question.
What is a human? What is a human self, a human individual? That's
more difficult. It's not a question I can answer - it's not a
question any scientist can answer at present, though I think they
will.
I believe it will turn out that what a
human is is some manifestation of brain stuff and its workings.
Susan Blackmore said recently in The
Skeptic: 'I think the idea we exist is an illusion. The idea that
there is a self in there that decides things, acts and is responsible
is a whopping great illusion. The self we construct is just an
illusion because actually there's only brains and chemicals and
this "self" doesn't exist - it never did and there's
nobody to die.'
Would you agree with that kind of reductionist
explanation of who your wife is, who you are?
Yes. I mean, Susan is sticking her neck
out for one particular view of what a self is, and it's one that
I am inclined to think is probably right; but I don't think we
are yet in a position to substantiate that.
What makes it seem plausible to me is
various things. One is that brains have come into the world by
a gradual process of evolution and we have a continuum from ourselves
through al the other animals to animals that have very simple
brains, to animals that have no brains at all, to plants.
Certainly, the prediction that we don't
survive death seems to me to be overwhelmingly probable. That
would be a good operational test - not that we can actually test
it, but in principle: if a self is something other than brain
stuff, then it should survive when the brain rots - and Id place
a very heavy bet (which I realise I could never actually win)
that when my brain rots my self will not in any sense exist.
Do you believe that the idea that I
exist is an illusion?
Well, I'm certainly happy that we are
a product of brains and that when our brains die, we disappear.
To call us an illusion is possibly a good
way to express it. But I wouldn't wish to commit myself to saying
that our sense of self is an illusion. It depends what you mean.
I certainly feel that there's a me.
Perhaps what you would need to test
that would be to see if somebody could die and come back to life.
Yes, I suppose that's right.
As a Christian I believe that has happened.
I know you do. But I don't.
But are you not open to exploring that
possibility?
I'm open to exploring any possibility
where there is some evidence. I don't wish to sound frivolous,
but there is an infinity of possible things that one might believe
- unicorns, fairies, millions of things - and just because you
can't disprove them it doesn't mean there is anything plausible
about them.
But there is no evidence for fairies
is there? And yet there is solid evidence for the resurrection
of Jesus.
I think you are on dangerous ground. There
have been many people who allege that they see fairies. The fact
is that we just don't believe them. We think they're hallucinating,
or lying.
Now, I don't know where the story of Jesus
rising from the dead comes from. The actual documentary evidence
is very bad as historical evidence goes, and so, given its enormous
inherent implausibility, I'd be much more inclined to suspect
it. You needn't go as far as to say 'hoax' - it's just that when
very, very charismatic people die, legends grow up about them
in a very mysterious way.
There are all sorts of legends knocking
around the world now of Elvis Presley having risen from the dead.
Numerous eye-witnesses. And you don't believe them, I presume.
I don't. I don't want to say these people are lying - maybe some
of them are, maybe they are just a bit crazy.
Elvis Presley has only been dead for about
15 years and already these legends are rife.
You could ask someone who believes
that Elvis has come back from the dead if they were prepared to
die for that belief. The people who believed Jesus had risen from
the dead were prepared to die.
Yes. That actually doesn't impress me
very much. I know there are a lot of people who are prepared to
die for all sorts of odd things. It's clearly evidence for some
sort of sincerity, I don't doubt that, but it doesn't seem to
me to be evidence of what they believed.
It's not a very fruitful line of questioning
as far as I'm concerned, because I'm not impressed by the historical
evidence and you are.
In the study guide for your 1991 Christmas
Lectures for Young People, you wrote: 'We are machines built by
DNA whose purpose is to make more copies of the same DNA. It is
every living object's sole reason for living.'
That's correct. 'Purpose', of course,
doesn't mean purpose in the same way that the purpose of switching
on a kettle is to make a cup of tea.
What is the distinction?
Well, that is a feeling of a goal in mind.
I want a cup of tea, so I'm going to put the kettle on.
The purpose of a bird's wing is to keep
the bird aloft. It's a different kind of purpose, because it's
not cognitively thought out. What it really means is that the
bird's ancestors that had wings did, in fact, stay aloft. It was
a good thing to do, so they had more children and so their descendants
inherited the same wings.
More fundamentally, to say that the purpose
of all life is to pass on their DNA means that all living things
are descended from a long line of successful ancestors, where
success means they have passed on their DNA. So, they are all
very good at passing on their DNA and they all contain organs,
apparatus, which can best be understood as fulfilling a purpose
of propagating DNA. It doesn't mean that anybody actually sat
down and thought that purpose out.
But there is no purpose other than
that?
There is no purpose other than that.
I sat once with an old man whose children
had left home and no longer needed him. If you like, he had nothing
more to do to continue his genes. And he broke down in tears and
said, "What is the purpose of my life?" What would you
say to him?
A brain like ours has a kind of overkill
of complexity. Natural selection has given us the brains we needed
to pass on our DNA in a particularly human way. On the African
plains, those brains became big and they developed the capacity
to set up purposes.
Originally, the purposes they were set
up for would have been useful ones like catching buffalo or finding
water or developing fire. But it's a consequence of building a
brain that can have mundane purposes that if you make it sufficiently
good, it will incidentally have the capacity to set up other purposes
which have nothing to do with mundane goals.
So, my purpose in writing, any of our
purposes in doing any of the things we normally do, makes use
of our brains' capacity to set up goals and follow them. You can
set up exceedingly worthwhile goals that give great satisfaction
in your brain and you can devote your life to following them,
where those goals have no connection with passing on DNA.
This old man could have been childless
but he could have been a brilliant composer, and his purpose in
life would have been to compose music. That's a perfectly good
purpose.
But the purpose we feel is an incidental
by-product?
When you have a purpose of finishing a
symphony, if you are a composer, from a DNA point of view that
is a by-product. When computers were first invented, they were
invented as calculating machines; but it didn't take any substantial
modification to turn them into word processors. It so happens
that if you build a really efficient programmable computer, it
will, willy-nilly, also be good at word-processing.
But our sense of purpose is illusory?
In Susan Blackmore's sense, it probably
is, yes - but that's not a point I want to emphasize. When I have
a purpose, like finishing a book, illusion or not, it certainly
feels like a purpose.
Jesus said that love is the purpose
of life. Does that sound nonsense to you?
It sounds like something grafted on, a
superfluous excrescence on life, which I feel I understand better.
But it doesn't surprise me that, brains
being what they are, they have a capacity to invent spurious purposes
of the universe which ...
You would say that love is a spurious
purpose?
Well, love is not a purpose, love is an
emotion (which I certainly feel) which is another of those properties
of brains.
A by-product?
Well, it's probably more than just a by-product.
It's probably a very important product for gene survival. Certainly,
sexual love would be, and so would parental love and various other
sorts of love.
But to say that love is the purpose of
life doesn't in any way chime in with the understanding of life
which I feel we have achieved.
A feature in The Independent on Sunday
a while ago said that when you and Lalla met, it was love at first
sight. What does that mean? What does the "I" in "I
love you" mean? What does "love" mean?
Well, we've been into that before. It's
an emotion which is a manifestation of brain stuff.
It's not possible to argue against that
point of view simply by multiplying examples of words like 'love'
or 'hate' or 'fear'. We use these words all the time; nobody denies
that we use them. I have already said, and Susan Blackmore said
it in slightly different terms, that we don't think that that
corresponds to anything other than the manifestation of brains.
You don't gain anything by asking the
same question again but substituting a new word.
Nietzsche talked contemptuously of
people who rejected Christianity but still held on to Judaeo-Christian
ideas. Is that not what you have done?
Well, there is a sense in which we are
prisoners of the language that we use, and the language that we
use in our culture is a language that has been shaped by the history
of our culture.
I think it's anthropologically interesting
to know whether the phrase "I love you" means something
totally different to somebody from an utterly different culture,
like a Trobriand Islander, and anthropologists seem to differ
a bit about that. This seems to me to be something you really
could look at. I could be persuaded that there are cultures for
whom the phrase "I love you" doesn't mean anything at
all; and maybe it does mean something to me because of my Judaeo-Christian
history. That's an interesting historical, sociological, psychological
question.
But if "I love you" has meaning
because of your Judaeo-Christian history, when you rejected God
shouldn't you also have rejected love?
I don't think so. We have now switched
from what we think is true about the universe to talking about
psychology and sociology.
Isn't it a matter of living with the
consequences? Someone has said that atheism is a faith which takes
great courage to live out wholeheartedly.
Well, I think there are two separate questions.
To take an analogy: it's sometimes said the Darwinian theory of
natural selection had to wait for the nineteenth century because
that was the right economic and political climate: 'the survival
of the fittest' was in the air. Well, that may or may not be true
- but it doesn't bear at all on the truth of Darwinism.
I mean, Darwinism is actually true of
the world of nature even if it had to wait until the 19th century
for people to think of it. So, it's one thing to say that Darwin
was a child of his time
I may say "I love you" and mean
what I mean by it because I'm a child of a Judaeo-Christian culture,
and that's an interesting historical point; but it doesn't mean
the Judaeo-Christian worldview is true. I can reject the worldview
while still remaining a child of the culture.
But shouldn't you also reject that
meaning?
Not necessarily. Well, I do reject the
metaphysical meaning, that there is an 'I' and a 'you' that are
going to survive death. I do reject that.
And that love is something more than
"Let's get together and continue our genes."?
I do reject that at an intellectual level.
But just as Darwin could be said to have
been a product of the economics of the time, yet what he believed
about nature was true for all time, always has been true, similarly
I am a product of a Judaeo-Christian culture. My language is absolutely
laced with biblical references, proverbs, poetry, metaphor. I
can't talk to other people in my culture without using it. But
it doesn't mean that the view of the cosmos with that biblical
culture is true or that I should believe it. Because I don't.
In The Selfish Gene, you distinguish
between a statement of what is and the advocacy of what ought
to be. We are born selfish but we need to teach generosity. Why
ought we to? You talk of altruism but fail to explain why we should
have the capacity for it. Doesn't consistency require you to reject
all that?
My main concern is to argue against people
who quite wrongly think that because you have shown that something
is, therefore it ought.
So, for example, I can show that from
a Darwinian point of view there is more Darwinian advantage to
a male in being promiscuous and a female being faithful, without
saying that I therefore think human males are justified in being
promiscuous and cheating on their wives. There is no logical connection
between what is and what ought.
Now, if you then ask me where I get my
'ought' statements from, that's a more difficult question. Firstly,
I don't feel so strongly about them. If I say something is wrong,
like killing people, I don't find that nearly such a defensible
statement as 'I am a distant cousin of an orang utan'.
The second of those statements is true,
I can tell you why it's true, I can bore you to death telling
you why it's true. It's definitely true. The statement 'killing
people is wrong', to me, is not of that character. I would be
quite open to persuasion that killing people is right in some
circumstances.
Going back to Nietzsche, in Beyond
Good and Evil he said: 'When [Christians] gave comfort to the
suffering, courage to the oppressed and despairing they have preserved
too much of that which ought to perish. [They have] worked at
the preservation of everything sick and suffering, which means
the corruption of the European race.'
Yes. I want to disown that very much.
I've just said and I'll say it again: I don't think that following
the dictates of Darwinism is necessarily what we ought to be doing.
I disagree with Nietzsche.
But I don't understand why. Nietzsche
would say the reason is that, although you have rejected God,
you haven't rejected your Judaeo-Christian heritage.
Well, that's possible. But now we are
back to a question about history and psychology.
Isn't it a question about consistency
in life?
When I am trying to explain the way things
are, I keep saying, it's nothing to do with the way we ought to
be. If I were consistent in the way you want me to be, I wouldn't
wear clothes because we didn't evolve with clothes. I wouldn't
waste my time writing books, or teaching students; I'd spend all
my life trying to have lots of children.
I see absolutely no reason why, understanding
the way the world is, you therefore have to promote it. The darwinian
world is a very nasty place: the weakest go to the wall. There's
no pity, no compassion. All those things I abhor, and I will work
in my own life in the interests of thoroughly unDarwinian things
like compassion.
In my worldview, you are created in
the image of God and that is why you know how you ought to be.
I can explain your compassion. I'm wondering how you can.
Well, one way to understand it is that,
by accident, we have evolved a brain which is powerful enough
to be able to look into the future and evaluate distant consequences.
So, I can see that to spend my whole life satisfying selfish whims
might make me less happy in the long run than if I spend it doing
something else like helping other people.
If you catch me giving money to Oxfam
and you say, "Why are you doing that?" and I can't answer
you, it doesn't seem to me that I have in any way betrayed my
belief in a godless cosmos.
If you challenged me with a fossil rabbit
which radioactive dating proved was 2000 million years old, that
would really be worrying. That would, at a stroke, disprove evolution.
Challenging me with being able to explain why I give money to
charity, that doesn't bother me very much.
Is it not a strong argument for the
Christian worldview? Where does that sense of 'ought' come from?
Yes, once again, I'm just not impressed.
I know that brains are complicated. Like music and mathematics,
it's something that was never part of the original survival package,
but the brain that produces it is. So, we have brains that are
there for Darwinian reasons and those brains have unforeseen consequences.
But the 'ought' is a by-product.
It's a by-product, yes.
Suppose some lads break into an old
man's house and kill him. Suppose they say: "Well, we accept
the evolutionist worldview. He was old and sick, and he didn't
contribute anything to society." How would you show them
that what they had done was wrong?
You credit them with rather more rational
thought than I suspect the real thugs would have had.
If somebody used my views to justify a
completely self-centred lifestyle, which involved trampling all
over other people in any way they chose roughly what, I suppose,
at a sociological level social Darwinists did - I think I would
be fairly hard put to it to argue on purely intellectual grounds.
I think it would be more: "This is
not a society in which I wish to live. Without having a rational
reason for it necessarily, I'm going to do whatever I can to stop
you doing this."
They'll say, "This is the society
we want to live in."
I couldn't, ultimately, argue intellectually
against somebody who did something I found obnoxious. I think
I could finally only say, "Well, in this society you can't
get away with it" and call the police.
I realise this is very weak, and I've
said I don't feel equipped to produce moral arguments in the way
I feel equipped to produce arguments of a cosmological and biological
kind. But I still think it's a separate issue from beliefs in
cosmic truths.
