"Dale Peterson adds originality and astonishing clarity to a discussion that has engaged science and philosophy in sometimes heated debate. This book is a delight to read. The Moral Lives of Animals will change the way many think of animals, and it will vindicate what others have always known intuitively. It deserves to be an instant bestseller."--Jane Goodall "Instead of humanity having developed morality from scratch, by means of its superior intellect, things may well have started simpler. In our fellow primates, we already recognize many of the tendencies that gave rise to the moral emotions. Dale Peterson does an excellent and engaging job explaining how the one may have led to the other. In doing so, he places us closer to other animals than many a moral philosopher would ever admit."--Frans de Waal, author of "The Age of Empathy". "The Moral Lives of Animals" is without question the most fascinating book I've read in many, many years--a marvelously written page-turner.
