An invaluable guide to avoiding the stuff of science-fiction nightmares.-John Gilby, Times Higher Education Moral Machines is a fine introduction to the emerging field of robot ethics. There is much here that will interest ethicists, philosophers, cognitive scientists, and roboticists.-Peter Danielson, Notre Dame Philosophical Reviews Written with an abundance of examples and lessons learned, scenarios of incidents that may happen, and elaborate discussions on existing artificial agents on the cutting edge of research/practice, Moral Machines goes beyond what is known as computer ethics into what will soon be called the discipline of machine morality. Highly recommended.-G. Trajkovski, CHOICE ...the book does succeed in making the essential point that the phrase 'moral machine' is not an oxymoron. It also provides a window onto an area of research with which psychologists are unlikely to be familiar and one from which, at some point, we may be able to learn quite a lot.-PsycCRITIQUES Moral Machines represents a valuable addition to, and extension of, the current literature on machine morality. As the development of autonomous artificial moral agents becomes closer to being realized, I suspect that this book will only gain in importance.-Metapsychology
