The basic premise of this book is a simple question: "What would you give up to save someone's life?" Drawing from thought exercises you can do yourself, controlled psychological studies, the teaching of many religions, examples from the lives of the rich, the poor, and the in-between, and from the vast range of global statistics on giving and on poverty, philosopher Peter Singer paints a compelling picture of how inconsistent our moral theories are with our true behaviour, and how only a small amount of giving on our part can save lives in the poorest parts of the world.
Singer's writing is absolutely lucid throughout, and there is never a moment where he loses the reader, or asserts something as true which is not obviously and apparently so once he has explained it. In fact, this book could stand as an example of the most clear and compelling writing on really any subject. Singer is, of course, not the first person to write this kind of book, and he won't be the last, but this is not simply a rehash of
North-South (The Brandt Report) or even
Rich Christians in an Age of Hunger: Singer brings to bear the latest in psychological research, and the actions and successes of the generation that grew up after the 1970s upswing in global responsibility, and in doing so he is able to counter many of the arguments for doing nothing which have grown up in reaction.
The fundamental tenet of this book is very simple: giving a part of our income does work, and we should all do it. The case that Singer makes for this is more or less watertight.
And yet, as he himself points out, the book has a fundamental weakness: it is likely to be bought and read by those who are already convinced of its argument, and are probably already doing something about it. This is a great pity, because this is a book which we very much need to read and to heed, especially in a time of recession when the reasons to not give will seem stronger than ever.
If you're interested enough to be reading this review, then you probably already share Singer's underlying convictions. My advice is, buy the book anyway. Reading it may refresh a flagging commitment to world justice. It may prove a hard book to lend out to un-likeminded friends, but if it just convinces one other person to set aside part of their income to save lives, then it will have achieved its purpose.
