This book has many virtues. The basic approach is strong and practical. Each principle and the exposition of each principle is embedded in real clinical moral problems. The authors make the interesting and important point that none of these principles have priority over another and that balances need to be sought between these principles. This book is simultaneously an excellent exposition of a strong approach to medical ethics and useful reference source to clarify thinking. The bibliography is excellent. Some of the chapters, notably the sections on autonomy and those on justice, are outstanding. The quality of writing is clear and the sections are distinguished by clarity of thought. The authors set themselves objective of writing a book that would combine a high level of rigor and would be useful, reaching a mixed audience of physicians, researchers, and others concerned with medical ethics. They have succeeded.
