A founder of the Deep Ecology Movement, Arne Naess has produced articles on environmentalism that provided unmatched inspiration for ecologists, philosophers, and activists worldwide. This collection amasses a definitive group of Naess’ most important works in which he calls for nonviolent, cooperative action to protect the Earth. Rich with observations, insights, and anecdotes, Naess’ writings draw from Eastern religious practices, Gandhian nonviolent direct action, and Spinozan unity systems. Playful and compassionate in tone, Ecology of Wisdom showcases Naess’ exceptional enthusiasm, wit, and spiritual fascination with nature, while educating readers about the steps they must take to rescue the planet and illuminating the relevance of this important environmental advocate.
