Bill Devall (d. 2009) was Professor Emeritus in Sociology at Humboldt State University, and the author of other books such as Clearcut: The Tragedy of Industrial Forestry, Simple in Means, Rich in Ends: Practicing Deep Ecology, and Living Richly in an Age of Limits. George Sessions is an Emeritus Professor of Philosophy at Sierra College, and edited Deep Ecology for the Twenty-First Century.
They wrote in the Preface to this 1985 book, "Many philosophers and theologians are calling for a new ecological philosophy for our time. We believe, however, that we may not need something new, but need to reawaken something very old, to reawaken our understanding of Earth wisdom... the themes in 'Deep Ecology' alternate between personal, individual options and public policy and collective options... the book offers an examination of the dominant worldview in our society, which has led directly to the continuing crisis of culture. We then present an ecological, philosophical, spiritual approach for dealing with the crisis."
They suggest that the major contribution of the science of ecology to deep ecology has been "the rediscovery within the modern scientific context that everything is connected to everything else." Ecology thus provided a view of Nature that was lacking in the "discrete, reductionistic approach to Nature" of the other sciences. (Pg. 85)
They observe that even in our highly technical society, "there are many who share these deep intuitions and the experience of the ritual journey into wilderness as 'sacred space.'" (Pg. 112)
They contrast deep ecology with the Christian notion of "stewardship" and with James Lovelock's position (Gaia: A New Look at Life on Earth) by asserting that the "narrowly utilitarian view" of natural resources still views natural resources as primarily for human use, and "fails to distinguish vital human needs from mere desires, egoistic arrogance and adventurism in technology." (Pg. 125)
This book is one of the foundational documents of the Deep Ecology movement, and will be of considerable interest to those interested in environmentalism, and earth spirituality.
