In it Vicki Hearne asserts that animals that interact with humans are more intelligent than we assume. In fact, they are capable of developing an understanding of the good, a moral code that influences their motives and actions. Hearne's thorough studies led her to adopt a new system of animal training that contradicts modern animal behavioral research, but as her examples show is astonishingly effective. Hearne's theories will make every trainer, animal psychologist, and animal-lover stop, think, and question.
