In the late 19th century, Charles Darwin was sure that humans and animals showed emotion through remarkably similar behaviors, noting, "The Indian elephant is said sometimes to weep." For over 100 years, animal lovers have known that their dogs, cats, and other pets have complex emotional lives. When Elephants Weep is the first book since Darwin's to thoroughly and effectively explore the full range of emotions throughout the animal kingdom. Scholar and psychoanalyst Masson, with the help of Susan McCarthy, presents scientific evidence, fascinating anecdotes, and illuminating insights that offer powerful proof of the existence of animal emotion. When Elephants Weep draws upon the illuminating experiences of animal trainers and pet owners to create riveting and revolutionary stories that will permanently change and enrich the way we look at animals.
