"The purpose is to bring together knowledge from a variety of scientific fields that should help people arrive at an informed judgment about animal suffering and to recognize when it is present in a given situation in a given animal species. The book does not present moral views but instead attempts to help readers in their thinking rather than telling them what to think. Such an objective is indeed a worthy one for all of us who have animal contact or care about the animal kingdom. This book meets its objectives extremely well, especially its goal of providing an objective reference for recognizing and understanding animal suffering rather than solely relying on subjective criteria."
