"Modern Environmentalism owes a great debt to philosopher, professor, and writer Arne Naess, co-founder of the Deep Ecology movement. Here, editors Alan Drengson and Bill Devall provide a comprehensive yet accessible volume of Naess's most groundbreaking and seminal essays, which have remained influential among environmentalists to this day." "These writings, full of Naess's characteristic enthusiasm, wit, and spiritual fascination with nature, provide a look into the remarkable philosophical underpinnings of his own social and ecological activism, as well as an inspiration for all those looking to follow in his footsteps."--Jacket.
