"The philosophical discussion of the five ethical prototypes on animal experimentation provides interesting insights into the main argumentative structures and logic of the arguments, and the author is largely committed to provide a robust foundation for his position. The knowledge about technical problems relating to genetic engineering in animals is solid." – in: Medicine, Health Care and Philosophy 14 (2011), 219–223"This book should appeal to a broad range of readers interested in the ethics of animal experimentation. It is particularly appropriate for scientists and others who have a limited background in the various philosophical positions used to criticize or support animal research. … The presentation is lucid and refreshingly nontechnical. … Nordgren stresses the ‘3Rs’ of animal experimentation: ‘replacement, reduction, and refinement’ … Recommended." – in: CHOICE 47/11 (July 2010)"a pleasant surprise. [Nordgren’s] clear analysis and imaginative insights jolt some tired debates out of accustomed ruts and provoke thought at a deeper and more satisfying level." – in: Animal Welfare 19/3 (August 2010)
