Tobias and Morrison draw on 45 years of research in fields ranging from ecological anthropology, animal protection and comparative ethics to literature and spirituality - and beyond. They deploy research in animal and plant behavior, biocultural heritage contexts from every continent and they bring to bear a deeply metaphysical array of perspectives that set this book apart from any other. The book departs from most work in such fields as animal rights, ecological aesthetics, comparative ethology or traditional animal and plant behaviorist work, and yet it speaks to readers with an interest in those fields. A deeply provocative book of philosophical premises and hypotheses from two of the world’s most influential ecological philosophers, this text is likely to stir uneasiness and debate for many decades to come.
