We need to recognise that what really matters isn't buying more and more consumer goods, but family, friends, and knowing that we are doing something worthwhile with our lives. Helping to reduce the appalling consequences of world poverty should be part of that reassessment.
Several countries - among them Austria, Costa Rica, Denmark, Finland, India, Israel and Sweden - ban or severely restrict the use of wild animals in circuses. In Brazil, a movement to ban wild animals from circuses started after hungry lions managed to grab and devour a small boy.
When I was a child, my father used to take me for walks, often along a river or by the sea. We would pass people fishing, perhaps reeling in their lines with struggling fish hooked at the end of them. Once I saw a man take a small fish out of a bucket and impale it, still wriggling, on an empty hook to use as bait.
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.
Knowing that we can control our own behaviour makes it more likely that we will.
If we use goods made from raw materials that are obtained from a poor country without the proceeds being used to benefit the people of that country, we become complicit in a particularly iniquitous form of grand larceny.
Every profession will have its rogues, of course, no matter what oaths are sworn, but many health care professionals have a real commitment to serving the best interests of their clients.
It was wrong to capture wild animals and confine them in captivity for people to go and gawk at them. And that's basically how zoos got started. But once you do that, and once you have animals that have been bred in captivity, you're really stuck with them in some sense. You can't return them to the wild.
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.
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.
I find it extraordinary that anyone would have an intellectual conversion to Roman Catholicism.
I just don't think that the differences you make by donating to a museum or an art gallery really compare to the differences you make by donating to the charities that fight global poverty.
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.
When you look at food as an ethical issue in the Christian tradition, you don't find very much about it. You don't find, as you do in the Jewish or Islamic or Hindu traditions, a lot of restrictions saying you can eat this but you can't eat that.
I don't think there's anything in the compromise that means that there's a clash of ethics.
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.
I suppose what's happened recently has confirmed suspicions I voiced in the book, and I think made clearer some of those things that I point out. For instance I have a section of the book where I talk about the possibility of torture.
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.
Scholars have long dreamed of a universal library containing everything that has ever been written.
I don't think nationalism is alone holding the field; it's in contention with a lot of different things.
