"Steven Holland�s Bioethics has become established as the best one volume introduction to philosophical bioethics. I recommend it warmly to students of philosophy and bioethics, but the general reader will also find it enjoyable and accessible. I am delighted to welcome its second edition."Richard Ashcroft, Queen Mary University of London"Anyone wishing to get their bearings on the fundamental philosophical questions about moral status, personal identity, life, death, killing, and appeals to nature, that underlie issues in bioethics, should start with Stephen Holland�s book. It is an excellent, balanced work that introduces bioethics in the way that it should be introduced, that is, with some philosophical depth."John P. Lizza, Kutztown University of Pennsylvania
