"In Animal Minds, Donald R. Griffin takes us on a guided tour of the recent explosion of scientific research on animal mentality. Are animals consciously aware of anything, or are they merely living machines, incapable of conscious thoughts or emotional feelings? How can we tell? Such questions have long fascinated Griffin, who has been a pioneer of research in animal cognition for decades, and is recognized as one of the leading behavioral ecologists of the twentieth century."--BOOK JACKET.
