number of people have died, including a man crushed when a pile

:00:00.:00:00.

of salt used for de-icing roads fell on him. Thousands of people have

:00:00.:00:00.

been stranded after the cancellation of more than 2,000 flights.

:00:00.:00:00.

Now on BBC News, HARDtalk. Welcome to HARDtalk. From genetic

:00:07.:00:16.

engineering to bioscience, humans are close to acquiring the ability

:00:17.:00:19.

not just to combat disease but to enhance and perfect our species.

:00:20.:00:32.

But should we seek to do it? Or should we shy away from the path

:00:33.:00:35.

that led to Nazi eugenics? My guest is Australian-born,

:00:36.:00:37.

Oxford-based medical ethicist Julian Savulescu. Can we trust ourselves to

:00:38.:00:42.

be wise masters of our own biology? Julian Savulescu, welcome to

:00:43.:01:15.

HARDtalk. It seems we humans have acquired

:01:16.:01:18.

extraordinary knowledge of how to re-engineer the genetic building

:01:19.:01:24.

blocks of life. Do you regard that as a profoundly positive thing? I

:01:25.:01:30.

think it is. Because we are, all, products of evolution. We aren't

:01:31.:01:36.

products of design. We aren't designed to live happily or live

:01:37.:01:42.

long-term or be peaceful. We are just the blind results of nature. Is

:01:43.:01:49.

that natural evolution? What we are going to talk about today is about

:01:50.:01:53.

human intervention. Human meddling. You can call it meddling or you can

:01:54.:02:16.

call it modification, what you like. The important thing to ask is, is

:02:17.:02:19.

the natural state of affairs the best state of affairs? There is huge

:02:20.:02:22.

variation in levels of aggression, intelligence. At the extreme ends we

:02:23.:02:25.

call them diseases. We call the bottom 2% diseased or disordered in

:02:26.:02:28.

some way. Why should we draw the line at 2%? Why not 50% or 30%? We

:02:29.:02:32.

now have the possibility of deciding what kind of beings we should be and

:02:33.:02:35.

what sorts of lives we should lead. To believe that's a good thing, one

:02:36.:02:39.

has to believe in the wisdom of human beings, to use the ability in

:02:40.:02:42.

a way that is both individually and collectively beneficial. It's

:02:43.:02:45.

certainly correct that with any powerful technology or intervention

:02:46.:02:47.

is the possibility of great good and great harm. We haven't been

:02:48.:02:54.

judicious masters of our technology, that's true. We have developed

:02:55.:02:59.

nuclear weapons. But can we, at this point, use it and will it be

:03:00.:03:02.

developed anyway and should we try to control its direction?

:03:03.:03:07.

Let's start with repairing disease. Few people these days have found

:03:08.:03:10.

ethical issues with the notion of genetic intervention used to prevent

:03:11.:03:13.

or fix some of the most difficult inherited diseases, like cystic

:03:14.:03:24.

fibrosis. That's a reality today, isn't it?

:03:25.:03:29.

It's certainly a reality that you can select to have children who will

:03:30.:03:33.

be free of that genetic mutation that causes cystic fibrosis. But for

:03:34.:03:38.

many characteristics to do with our mental lives, like psychiatric

:03:39.:03:40.

disorders, the line that's drawn is arbitrary. 10% of children now have

:03:41.:03:49.

this new disease called attention deficit disorder. That's called a

:03:50.:03:54.

disease but suddenly 10% of children have this disease warranting

:03:55.:03:59.

treatment. I believe that, in many of these cases, these are normal

:04:00.:04:02.

human variations that are just disadvantageous. Science now gives

:04:03.:04:09.

us the ability of improving those. You go further than just discussing

:04:10.:04:12.

the possibilities that science offers. You seem to believe there is

:04:13.:04:17.

some sort of philosophical or moral obligation upon parents, who live in

:04:18.:04:20.

a context where this technology is available, to use it, enhance and

:04:21.:04:23.

maximise the potential of their progeny? Am I right?

:04:24.:04:35.

As parents, most people want to have... Want their children to have

:04:36.:04:39.

the best lives they can have. But it's a moral obligation? As we

:04:40.:04:42.

look forward and technology becomes more pervasive, would you, as a

:04:43.:04:45.

philosopher and ethicist, say to a parent who is offered the chance to

:04:46.:04:48.

take advantage of this technology and to turn maybe just a kid, who

:04:49.:04:52.

genetically looks like he might be under average, is there a

:04:53.:04:54.

responsibility to intervene and make that kid above average? To make it

:04:55.:05:08.

enhanced? If it makes his or her life the

:05:09.:05:12.

better, yes. By moral obligation I mean that there is a reason to do

:05:13.:05:18.

it. We should do lots of things, provide a good education to

:05:19.:05:20.

children, provide diet and treat diseases. Where there are things

:05:21.:05:28.

like vitamins or nutritional supplements that improve their

:05:29.:05:30.

intelligence or reduce unwarranted aggression, then we should use those

:05:31.:05:35.

in the same way. It sounds like strong language. I'm not saying

:05:36.:05:42.

people should be required by law to do these things but we should

:05:43.:05:44.

encourage people and using terms like moral obligation is not to say

:05:45.:05:49.

that's what they must do. There's a good reason to do it. The reason is,

:05:50.:05:54.

the child is expected to have a better life.

:05:55.:05:56.

This is a quote from you. "Technology allows us to avoid the

:05:57.:05:59.

lottery of life, to choose our destiny". Such a strong statement

:06:00.:06:06.

and it brings to my mind the word hubris. If humans start talking

:06:07.:06:10.

about choosing and deciding their destinies, that is hubris, is it

:06:11.:06:16.

not? It can be but it's also important to

:06:17.:06:19.

realise that there is enormous inequality and disadvantage. We are

:06:20.:06:24.

two of the lucky ones. We are sitting here having a comfortable

:06:25.:06:30.

conversation. There are many people who have a life of extraordinary

:06:31.:06:32.

disease, disability, disadvantage and really being born behind the

:06:33.:06:35.

eight ball, not only socially but in terms of biological obstacles to

:06:36.:06:38.

them being able to just do the basic things in life, like work. If we

:06:39.:06:49.

have a chance to overcome that, why shouldn't we ask ourselves whether

:06:50.:06:54.

we should? Maybe because it's going down a

:06:55.:06:59.

dangerous path. It's a mindset which the philosopher and ethicist Michael

:07:00.:07:01.

Sandel says is undermining one of the most basic and important

:07:02.:07:04.

qualities we, as humans beings, have. That's humility and openness

:07:05.:07:17.

to be unbidden. I have been open to the unbidden.

:07:18.:07:21.

Why shouldn't we remain open to being unbidden? Why should we try to

:07:22.:07:27.

determine our destiny by meddling with genes?

:07:28.:07:29.

When you provide education to children, it changed their brains.

:07:30.:07:31.

You modify them. You do that according to certain values.

:07:32.:07:39.

What is the moral or any other equivalent between genetic

:07:40.:07:41.

engineering of the human embryo and sending your kid to school?

:07:42.:07:46.

There's no morally relevant difference. Both change the way the

:07:47.:07:50.

brain works. One acts directly, one acts through social mechanisms. The

:07:51.:07:54.

final common pathway is what's going on in people's brains. If you can

:07:55.:07:58.

use knowledge of science, in this case genetics, to augment the

:07:59.:08:01.

effects of education, why would you draw an arbitrary line, just because

:08:02.:08:04.

you think it's an internal modification rather than external?

:08:05.:08:13.

Why would that make a difference? Maybe we can tease that out with

:08:14.:08:18.

some examples. Starting with one of the most basic uses of genetics that

:08:19.:08:22.

people may be aware of. That is, gender selection. For a long time

:08:23.:08:29.

now people have been able to look at the fertilised embryo and see what

:08:30.:08:34.

gender it is. You have taken a strong position on this, saying it's

:08:35.:08:38.

a basic human right. That everybody should be allowed to choose the sex

:08:39.:08:47.

of their baby. We have the right to choose when to

:08:48.:08:50.

have children, how many children to have, now we have the possibility of

:08:51.:08:53.

choosing between possible children. If you are going to restrict liberty

:08:54.:08:56.

in a liberal democratic society, you need to have a reason based on a

:08:57.:09:02.

risk of harm to people. You can't go around willy-nilly, stopping people

:09:03.:09:04.

doing what they want, unless they are really harming somebody. When it

:09:05.:09:10.

comes to sex selection, who are they harming? There are several possible

:09:11.:09:14.

candidates but the usual one is society or women by creating sex

:09:15.:09:26.

ratio imbalances. Which we see all over the world.

:09:27.:09:29.

Not reducing genetic technologies but basically by prenatal testing

:09:30.:09:32.

and abortion or infanticide. But when it comes to the use of these

:09:33.:09:35.

technologies, if you could demonstrate a harm to women or

:09:36.:09:38.

society, that would be a good reason to ban it, but you could easily

:09:39.:09:43.

prevent this. You simply allow for what you call family balancing,

:09:44.:09:46.

allowing it for the second or third child of a family who want a mix of

:09:47.:09:52.

sexes. You can monitor the sex ratio, there are many ways in which

:09:53.:09:55.

you can ensure that these sorts of harms don't occur.

:09:56.:10:00.

You talk about this in the context of a liberal, free, rich world

:10:01.:10:05.

society. Are you accepting that if you were to apply the logic of

:10:06.:10:08.

freedom to choose, for individual parents on this gender question, in

:10:09.:10:11.

many societies you would end up with a terribly unbalanced gender

:10:12.:10:14.

situation inside the country and it would also entrench the second class

:10:15.:10:17.

status and the disempowerment of so many women and so many societies?

:10:18.:10:30.

If it had those effects... It would.

:10:31.:10:34.

Then it would be a good reason to ban it in those societies.

:10:35.:10:42.

Having a basic human right in respecting freedom is always limited

:10:43.:10:45.

by the harm that you present to other people. In this case, there is

:10:46.:10:49.

a clear harm to women. But if we don't have a grave social problem,

:10:50.:10:52.

we shouldn't be infringing people's liberty.

:10:53.:10:58.

Imagine a world where the science of genetics has gone even further than

:10:59.:11:02.

it has today and one can look at the fertilised embryo and draw all sorts

:11:03.:11:05.

of conclusions about things you have already mentioned. Intelligence,

:11:06.:11:09.

likelihood of an inclination to violent or criminal behaviour.

:11:10.:11:18.

Coming back to moral obligation, do you believe in those circumstances

:11:19.:11:20.

there is a moral obligation to intervene? End those pregnancies

:11:21.:11:34.

which involve embryos with those signatures or to somehow repair

:11:35.:11:35.

them? Again, this is the reason amongst

:11:36.:11:38.

others. I have never suggested that people have a moral obligation to

:11:39.:11:41.

have termination of pregnancy. That's a very serious intervention.

:11:42.:11:46.

What I have been discussing is when you have ten embryos and you have

:11:47.:11:49.

tested them all for diseases... Like IVF?

:11:50.:11:55.

This is the simplest case. You will soon be able to sequence the embryos

:11:56.:12:01.

and you have found they are healthy. Why wouldn't you go on to look for

:12:02.:12:04.

their dispositions towards intelligence or towards psychopathy?

:12:05.:12:07.

1% of the population are psychopaths. We might identify the

:12:08.:12:18.

genetic contributions to psychopathy, not to say it's

:12:19.:12:21.

genetic, but those things that make it more likely and why wouldn't you

:12:22.:12:23.

take that information into account when deciding... You will implant

:12:24.:12:27.

one of those ten embryos. Why not choose the one that has a lower

:12:28.:12:29.

chance... That sounds dangerously like

:12:30.:12:31.

eugenics, when you take away all the traits, all of the huge numbers of

:12:32.:12:35.

different traits that make up human beings, and you try to develop a

:12:36.:12:44.

successful stereotype. We are in a completely different

:12:45.:12:47.

world to the world of the past. It's true, this is eugenics. It is

:12:48.:12:53.

eugenics when you test for cystic fibrosis or Down's syndrome, that's

:12:54.:12:56.

trying to have a child who is healthier or has less intellectual

:12:57.:13:01.

disability. That's healing a real impairment.

:13:02.:13:06.

What you are now talking about is trying to perfect, trying to

:13:07.:13:09.

maximise, the benefit to any newborn individual. For example, you might

:13:10.:13:15.

say in a deeply prejudiced society, where it's difficult being an ethnic

:13:16.:13:19.

minority, being black or being gay, then you should meddle with the

:13:20.:13:21.

genetic material before birth in IVF, for example, to lighten the

:13:22.:13:24.

scheme or to avoid having the genetic disposition to

:13:25.:13:26.

homosexuality, because that would create such problems for the future

:13:27.:13:36.

child. Is that what you would contemplate?

:13:37.:13:41.

You also have the obvious strategy of reducing... Good memory

:13:42.:13:49.

institutions. That's politics. But in the short

:13:50.:13:54.

term, as a scientist, you are faced with the issue, do I get rid of the

:13:55.:13:58.

embryo that is physically disabled or predisposed to being homosexual,

:13:59.:14:00.

because the individual, if born, would have a much more difficult

:14:01.:14:03.

life than the perfect stereotype that I'm seeking? As I said, there

:14:04.:14:17.

are a number of ways to address this kind of problem and one of them is

:14:18.:14:23.

through social intervention. That does not answer my question. Imagine

:14:24.:14:29.

the society is not fixed, it has not worked the way you would like it to

:14:30.:14:37.

work. But you still have to decide. Do you think it's legitimate to

:14:38.:14:40.

decide on the basis that I just outlined to get rid of the embryo

:14:41.:14:43.

that is predisposed to be homosexual or might have a physical impairment?

:14:44.:14:49.

Because, to use your logic, why wouldn't you? Why not take the

:14:50.:14:58.

embryo and maximise its own advantage? From the perspective of

:14:59.:15:01.

the child that is born, in considering whether their life goes

:15:02.:15:04.

well, you have to consider these unjust institutions and choose the

:15:05.:15:06.

child that will have the better future. But there are other reasons

:15:07.:15:14.

not to bend to these forces. Perhaps they want to change these unjust

:15:15.:15:17.

practices by resisting this kind of choice. But you have to remember

:15:18.:15:25.

that you are not doing that for the benefit of the child, you're doing

:15:26.:15:28.

that to change society. And the reasons why people choose to have

:15:29.:15:31.

boys in India... There are two reasons. First, if you have a girl,

:15:32.:15:35.

you have to have a very large dowry. For poor people, it's very expensive

:15:36.:15:39.

to have a girl. The problem there is the institution of the dowry. If you

:15:40.:15:44.

are a poor person and you cannot afford a dowry, there is a very good

:15:45.:15:48.

reason for you to select to have a boy. The problem in these cases is

:15:49.:15:52.

not just to say that you are perpetuating this problem. You have

:15:53.:15:59.

to address the causes not the symptoms of the disease. The causes

:16:00.:16:02.

are homophobic attitudes, racism, and outdated social institutions.

:16:03.:16:05.

Those are the causes. Of course, if you cannot treat the disease, you

:16:06.:16:07.

have to consider symptomatic treatment. Thereby entrenching those

:16:08.:16:16.

very institutions. And that might be a reason not to administer

:16:17.:16:22.

symptomatic treatment. But you are picking a case where... You are

:16:23.:16:26.

clearly an ethicist and you have to deal with it. Ethics is about not

:16:27.:16:29.

considering one reason but to consider all relevant factors. You

:16:30.:16:38.

cannot make a decision in theory about the rightness or wrongness of

:16:39.:16:41.

selection that applies in every single circumstance. I don't want to

:16:42.:16:48.

suggest this is simple. It's complex.

:16:49.:16:52.

Human cloning. Do you believe that the ultimate logic of what you

:16:53.:16:57.

suggest about perfecting - enhancing and perfecting human genetic

:16:58.:17:02.

material - does lead to cloning? Taking the very best and replicating

:17:03.:17:06.

it? Well, again, if that were your only goal, to have the most gifted

:17:07.:17:14.

possible child, then... Sometimes it sounds like that is your goal. No,

:17:15.:17:18.

it's not. Sometimes we have a reason. But sometimes people want to

:17:19.:17:21.

have their own child, not Albert Einstein's child or Michael Jordan's

:17:22.:17:26.

child. You would need to have a good reason to clone. Here is one.

:17:27.:17:30.

Imagine if you were infertile and could only produce one or two

:17:31.:17:35.

embryos. You cannot produce anymore eggs. And you have a pregnancy and

:17:36.:17:41.

it looks like the pregnancy will be lost. But you can clone that foetus

:17:42.:17:45.

in utero in case the pregnancy miscarries. That seems an entirely

:17:46.:17:53.

legitimate use of cloning technology if you could do it, to enable that

:17:54.:17:58.

couple to have a child. Yes, it would be a clone, but so what? One

:17:59.:18:07.

line you appear to be happy to cross is cross-species genetic mixing. You

:18:08.:18:10.

talk about a future in which the human being might have, to quote

:18:11.:18:14.

you, sonar ability like a bat, or indeed, the ability to convert

:18:15.:18:16.

sunlight into energy for growth like a plant. I know that this is

:18:17.:18:28.

blue-sky thinking, but you don't have an ethical problem with this

:18:29.:18:30.

cross-fertilisation of genetic material? Again, it's important to

:18:31.:18:33.

start with the science and the facts. We are the result of

:18:34.:18:39.

integration of viral DNA into our genome. A lot of our genetic

:18:40.:18:43.

material is viral. We are already integrating stuff from the

:18:44.:18:47.

environment. Now, if I had a gene sequence that could confer

:18:48.:18:49.

resistance to HIV that came from some other animal, that was

:18:50.:18:52.

constructed in a laboratory and put into people to prevent the spread of

:18:53.:18:56.

HIV, you have to ask why is the fact that it comes from an animal

:18:57.:18:59.

different from the fact that you just invented it in a laboratory? In

:19:00.:19:07.

fact, you could just copy the sequence and construct it in a

:19:08.:19:12.

laboratory. The question is, what are the risks and benefits of the

:19:13.:19:15.

particular case under consideration? If we ran out of food and we could

:19:16.:19:19.

then use sunlight to produce energy, why would that be... Certainly

:19:20.:19:24.

unnatural, but why would it be wrong? Risks and benefits. It's

:19:25.:19:30.

always a difficult calculation. You have been talking about futurology

:19:31.:19:32.

to some extent but let's bring it back to something real, which is

:19:33.:19:35.

your stance on performance-enhancing drugs in sport. You have made a big

:19:36.:19:38.

noise around the world, saying that you believe it is right to allow

:19:39.:19:41.

athletes, cyclists, to use performance-enhancing drugs, even

:19:42.:19:44.

though many of those same athletes say that it is absolutely not the

:19:45.:19:50.

way they want their sport to go. Why is that? The rules of sport are

:19:51.:19:56.

entirely arbitrary. There is no inherent rightness or wrongness in

:19:57.:20:00.

the set of rules. You choose them according to various values. Some of

:20:01.:20:05.

those values include their ability to be enforced, the ability to

:20:06.:20:08.

protect the health of participants, the ability to create a fair playing

:20:09.:20:11.

field that is enforceable. The current regime involves, today, what

:20:12.:20:14.

athletes are actually doing today is not what the East Germans did in the

:20:15.:20:17.

1970s, taking massive doses of drugs to turn women into men. They are

:20:18.:20:22.

moving within the natural range for all of these parameters. Blood,

:20:23.:20:26.

testosterone, growth hormone. And it's virtually impossible to detect

:20:27.:20:28.

whether someone is moving within this normal range and it's safe

:20:29.:20:31.

because it's within this normal range. But if you persist in this,

:20:32.:20:39.

you turn sport into a contest between scientists rather than a

:20:40.:20:45.

contest between physical athletes. Because the best drugs will win. Of

:20:46.:20:55.

course, you could if you again moved into supra-normal doses of these

:20:56.:20:58.

things. You seem to miss the human element. To quote you from Bradley

:20:59.:21:01.

Wiggins. He says he has never used drugs, in a sport which has been

:21:02.:21:05.

tainted by drugs. He says, "I do what I do because I love it. I don't

:21:06.:21:09.

do it for a power trip. What I love is doing my best and working my

hardest. If I felt I had to take drugs in my sport, I would quit

:21:14.:21:18.

tomorrow". Well, they do take substances. Caffeine used to be

:21:19.:21:25.

banned. It's not a naturally-occurring substance. It's

:21:26.:21:34.

now permitted. It increases the tolerance of the body. Other

:21:35.:21:37.

examples include analgesics. Local anaesthetics. Non-steroidal ones. It

:21:38.:21:41.

enables them to deal with the pain and damage of competition. Nearly

:21:42.:21:45.

100% of footballers are on these sorts of drugs to enable them to

:21:46.:21:48.

perform better. They are very unnatural and they are dangerous but

:21:49.:21:51.

nobody perceives them to be performance-enhancing drugs, but of

:21:52.:21:55.

course they are. That's why they give them. You put an enormous

:21:56.:22:01.

amount of faith and trust in humanity to use ever expanding

:22:02.:22:03.

scientific, biological knowledge to the best effect, for the best good

:22:04.:22:10.

of us as a species. There is one area where you seem to fall down in

:22:11.:22:13.

that approach and that's bioscience, where you have admitted you're

:22:14.:22:16.

terrified by the capacity of human beings to create a new pathogen,

:22:17.:22:19.

which could actually wipe us all out. Are you terrified because of

:22:20.:22:27.

what bioscience can do or are you actually terrified because you have

:22:28.:22:30.

come to realise that human beings, we ourselves, are actually pretty

:22:31.:22:37.

dangerous? I don't have great faith in human beings and their ability to

:22:38.:22:40.

make decisions about this technology at all. We are the most dangerous

:22:41.:22:46.

species on the planet. We may extinguish all life on the planet.

:22:47.:22:51.

Don't get me wrong. And yet you want to give us all these freedoms to

:22:52.:22:55.

meddle with nature. When it comes to meddling on the level of allowing

:22:56.:22:57.

people to choose their family, yes, they should have freedom, but what I

:22:58.:23:01.

would say is that once science gives us the knowledge and power, we have

:23:02.:23:05.

to make a decision and we have to make it on the basis of values and

:23:06.:23:10.

ethics. What I have argued in terms of sport and genetic selection is

:23:11.:23:13.

that once you can make a difference, you have to ask if you should stay

:23:14.:23:17.

with the status quo or if you should not. And if you choose to stay with

:23:18.:23:22.

the status quo, you are then responsible for it. In all these

:23:23.:23:26.

areas, we have to start thinking because unavoidably, science is

:23:27.:23:29.

giving us the power to make these sorts of changes. My point is that

:23:30.:23:34.

we need to have a set of values. What I have argued with sport is

:23:35.:23:38.

that you can have a set of values that allows a level of safe

:23:39.:23:41.

performance enhancement that would be not threatening to the human

:23:42.:23:44.

contribution and would be much more enforceable and would make the whole

:23:45.:23:48.

thing better. That is just a proposal. We know it's up for

:23:49.:23:51.

debate. But that's what ethics is about - making proposals. And plenty

:23:52.:23:54.

of debate. Thank you for joining us. There will be spells of wet and

:23:55.:24:34.

windy weather over the next two or three days. If you have any concerns

:24:35.:24:37.

about the flooding situation, call the floodline number. The reason we

:24:38.:24:46.

had such a wet and
