This book has a single motif and a dual purpose. Its motif is the portrayal of influential authors within an environmental framework and worldview. The design is presented in different ways in which environmental understandings might be understood. The purposes are to engender in the reader a broad knowledge of some of the ideas and problems inherent in a discussion of nature and the environment and to stimulate the reader to go further into the sources of their tradition and worldview in search of meaning and insights that are uniquely relevant to their philosophy.
