Privacy about giving is counterproductive. There is solid scientific research showing that people are more likely to give if they can see that others are giving. The richest people, in particular, should be setting an example.
Business ethics has always had problems that are distinct from those of other professions, such as medicine, law, engineering, dentistry, or nursing.
In most countries, it is possible to visit zoos and see bored animals pacing back and forth in cages, with nothing to do but wait for the next meal. Circuses are even worse places for animals. Their living conditions are deplorable, especially in travelling circuses where cages have to be small so that they can go on the road.
At the descriptive level, certainly, you would expect different cultures to develop different sorts of ethics and obviously they have; that doesn't mean that you can't think of overarching ethical principles you would want people to follow in all kinds of places.
For example, one way of giving yourself a strong incentive to reach your goal is to commit to pay money to someone if you fail. Better yet, you can specify that you will have to pay a certain sum to a cause that you detest.
If we can put a man on the moon and sequence the human genome, we should be able to devise something close to a universal digital public library.
When diamonds' role in fuelling violent conflict in Africa gained worldwide attention, the diamond industry established the Kimberley process in order to keep "blood diamonds" out of international trade.
Of those who die from avoidable, poverty-related causes, nearly 10 million, according to UNICEF, are children under five. They die from diseases such as measles, diarrhea, and malaria that are easy and inexpensive to treat or prevent.
The price we are willing to pay for safety cannot be infinite. It is distasteful to put a price on human life, but the more we spend on safety, the less we will have for our other goals.
Dolphins are social mammals, capable of enjoying their lives. They form close bonds with other members of their group.
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.
What you could say, and what I do argue in the book, is that he doesn't have as much concern for the lives of Iraqis as he does for the lives of Americans, or even frozen American embryos.
Many European countries, as well as Australia, Canada, Israel, and New Zealand, have adopted legislation that creates a 'public lending right', where the government recognises that enabling hundreds of people to read a single copy of a book provides a public good, but that doing so is likely to reduce sales of the book.
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.
Can we really believe that we are living a good life, an ethically decent life if we don't do anything serious to help reduce poverty around the world and help save the lives of children or adults who are likely to die if we don't increase the amount of aid we are giving.
Of all the arguments against voluntary euthanasia, the most influential is the 'slippery slope': once we allow doctors to kill patients, we will not be able to limit the killing to those who want to die.
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.
More often there's a compromise between ethics and expediency.
I would like us to think about it more explicitly, and not take our intuitions as the given of ethics, but rather to reflect on it, and be more open about the fact that something is an ethical issues and think what we ought to do about it.
If we are concerned about the exploitation of human workers in countries with low standards of worker protection, we should also be concerned about the treatment of even more defenceless non-human animals.
