"The contributors are all experts in the field, and this shows in the quality and breadth of information provided... the Companion is still the best secondary source in navigating the complex and ever-evolving field of bioethics." (Metapsychology, December 2010)

"The second edition of A Companion to Bioethics, edited by ethicists Singer (Princeton) and Kuhse (Monash Univ., Australia), should be... a standard one-volume reference work in the field of bioethics. The book's helpful summary of the field's major debates makes it especially helpful for smaller collections that do not procure many of the increasingly specialized monographs on narrow bioethical issues. The book also features a wide range of authors-- from such established scholars as James Childress and the late R. M. Hare to new voices in the field, such as Eric Gregory, who contributes an essay titled "Religion and Bioethics." The essays in the collection are accessible to many levels of readers; those unfamiliar with these debates will find the essays helpful introductions, and specialists will find new readings of classic works or new perspectives on old debates. This important, comprehensive, and superbly edited reference work will prove useful to students and scholars at all levels and a worthwhile addition to all collections." (CHOICE, July 2010)

"The reader or student who is interested in bioethics and wants to get a picture about the main questions on this subject will find excellent answers in this exquisite publication edited by Helga Kuhse and Peter Singer. The goal of the editors was to give as complete a picture as possible, choosing very carefully from the theme of bioethics; they succeeded in their goal. This success was achieved because the authors of the book are acknowledged and respected scientists and teachers of bioethics, and they used their experience to give the reader an insight into their subject material." (Nursing Ethics)

"Although the growth of bioethical discussion and practice has been huge in the last decades, the contents of the book provide a good introduction to the whole of the discipline, from discussions about the relationship between bioethics and law, culture, gender, or religion, to a survey of the different approaches available in ethical theory…. Together with an useful index and directory, and its accompanying volume of classical texts Bioethics: An Anthology, … this book provides an ideal basis for course and committee use in this field, and will be of interest to doctors, therapists, lawyers, journalists, and philosophers alike. Not to forget, of course, patients -- a group we all are likely to join at one time or another." (MentalHelp.net)

"A splendid work, covering the entire field of bioethics in a very readable way."
