I believe that nationalism is a very strong force, but there are other forces operating; there are tendencies pushing towards a larger picture, especially in Europe, I think; but I still think nationalism is real.

There is no doubt that the world economy is in trouble. But if governments or individuals use this as an excuse to reduce assistance to the world's poorest people, they will only multiply the seriousness of the problem for the world as a whole.

Dolphins are social mammals, capable of enjoying their lives. They form close bonds with other members of their group.

If governments did not mislead their citizens so often, there would be less need for secrecy, and if leaders knew they could not rely on keeping the public in the dark about what they are doing, they would have a powerful incentive to behave better.

My own view is that being a vegetarian or vegan is not an end in itself, but a means towards reducing both human and animal suffering and leaving a habitable planet to future generations.

We have a new generation of very rich people who want to do more with their money than buy a lot of expensive toys. They want to live meaningful lives.

As we realize that more and more things have global impact, I think we're going to get people increasingly wanting to get away from a purely national interest.

If you're buying animal products and can go to the farm and actually see how the animals are looked after, yes, that's an important point. That's definitely the best way of assuring yourself that the animals are being well treated.

We tend to think that people are more to blame for their acts than for their omissions.

When fish experience something that would cause other animals physical pain, they behave in ways suggestive of pain, and the change in behaviour may last several hours.

There is no humane slaughter requirement for wild fish caught and killed at sea, nor, in most places, for farmed fish.

Open government is, within limits, an ideal that we all share. U.S. President Barack Obama endorsed it when he took office in January 2009.

More people with HIV/Aids are getting inexpensive anti-retroviral drugs, and their life expectancy has increased, but universal access is still far off, and the disease is still spreading, if more slowly than before.

All I say about severely disabled babies is that when a life is so miserable it is not worth living, then it is permissible to give it a lethal injection. These are decisions that should be taken by parents - never the state - in consultation with their doctors.

I don't understand the notion that modern farming is anything do to with nature. It's a pretty gross interference with nature.

The hope of Internet anarchists was that repressive governments would have only two options: accept the Internet with its limitless possibilities of spreading information, or restrict Internet access to the ruling elite and turn your back on the 21st century, as North Korea has done.

They tend to be pretty abstract ones then, like doing what will have the best consequences; obviously you wouldn't specify what consequences are best, they may be different in some circumstances, so at a lower, more specific level, you may well get differences.

I don't eat meat. I've been a vegetarian since 1971. I've gradually become increasingly vegan. I am largely vegan, but I'm a flexible vegan. I don't go to the supermarket and buy non-vegan stuff for myself. But when I'm traveling or going to other people's places, I will be quite happy to eat vegetarian rather than vegan.

I'm a Utilitarian, so I don't see the rule against lying as absolute; it's always subject to some overriding utility which may prevent its exercise.

Scholars have long dreamed of a universal library containing everything that has ever been written.

Well the real concept of basic needs if you cut it right down are simply the physical needs that are unavoidable for all of us. So to have enough calories to keep our bodies going. Have shelter from extreme elements. To have water that is safe to drink, So I think that's the core of it.

We should aim for our children to be good people, and to live ethical lives that manifest concern for others as well as for themselves.

Do business managers have a commitment to anything more than the success of their company and to making money? It would be hard to say that they do. Indeed, many business leaders deny that there is any conflict between self-interest and the interests of all.

Some vegetarians and vegans may object to in vitro meat, because they don't see the need for meat at all. That's fine for them, and of course they are free to remain vegetarians and vegans and choose not to eat in vitro meat.

I have never really been fond of animals. I certainly wasn't an 'animal lover' when I became involved in the movement. I just came to be persuaded that animals should be treated as independent sentient beings, not as means to human ends.

Had Rumsfeld said at any time 'get me a report on what's going on', he could have had it. You're right, it depends on choices that we make, which parts of the world we want to be in immediate contact with.

Google has withdrawn from China, arguing that it is no longer willing to design its search engine to block information that the Chinese government does not wish its citizens to have. In liberal democracies around the world, this decision has generally been greeted with enthusiasm.

I would just like to get him to think about these things; whether what's happening in Iraq is promoting the culture of life. The worry is that he is so certain that he know where he's going to lead the country.

It means that, in fact, it's - whether fascist is the right word I don't know - more of a plutocracy than anything resembling a democracy; it has become a nation controlled by a very small, very wealthy elite.

Today, if you have an Internet connection, you have at your fingertips an amount of information previously available only to those with access to the world's greatest libraries - indeed, in most respects what is available through the Internet dwarfs those libraries, and it is incomparably easier to find what you need.

Paradoxically, resource-rich developing countries are often worse off than comparable countries that lack those resources. One reason for this is that large resource endowments provide a huge financial incentive for attempts to overthrow the government and seize power.

The Internet, like the steam engine, is a technological breakthrough that changed the world.

It's because I work in ethics, and, more specifically, applied ethics, that I think it's important that if you have things to say that you think are right and you think could make the world a better place, it's important that many people read about them.

Most of the robots being developed for home use are functional in design - Gecko's homecare robot looks rather like the Star Wars robot R2-D2. Honda and Sony are designing robots that look more like the same movie's 'android' C-3PO.

I think I get angry when people cause serious suffering or don't alleviate suffering when they could.

You might hold an ethical position that it's wrong to lie, but if you have plans for a war in Iraq, and you want to keep them secret for practical reasons - to reduce casualties, perhaps - and someone asks you about those plans, you may need to lie for a 'good' outcome.

So, basically, my view is I don't want to support the exploitation of animals, and within reason, I will do what I can to avoid it, but it's not like it's a religion for me. It's not like I consider I'm polluted if somehow some bit of milk or cheese or something passes my lips.

It's also much clearer how much damage the occupation of Iraq is doing to America's reputation and prestige around the world; and that's just starting now to hit home in the United States.

We may feel the pain of falling back from a level of affluence to which we have grown accustomed, but most people in developed countries are still, by historical standards, extraordinarily well off.

In an ideal world, the amount of money we spend on medical research to prevent or cure a disease would be proportional to its seriousness and the number of people who suffer from it.

The idea that we can actually have an impact on places more or less instantly, too, by responding in some way or not responding, I think, also makes it true.

But I think the majority of cows, and even more so chickens and pigs, are leading pretty miserable lives.

I don't think there's anything in the compromise that means that there's a clash of ethics.

Grain that is used to feed animals that end up on our tables as turkeys and hams could have gone to feed starving people.

Almost everybody accepts that some people can be killed. 'The concept of 'brain death' - the belief that people on respirators can legitimately be killed - shows that.

The notion that human life is sacred just because it is human life is medieval.

Animals, or at least those who are conscious and capable of suffering or enjoying their lives, are not things for us to use in whatever way we find convenient.

If we all think only of our own interests, we are headed for collective disaster - just look at what we are doing to our planet's climate.

So I think ethics is the broader thing that's less focused on prohibitions and is more perhaps looking at principles and questions and ideas about how to live your life.
