"Ecosophy is an “identification so deep that one’s own self is no longer adequately delimited by the personal ego or the organism” -Arne Naess

Philosophy

The term Deep Ecology was coined in 1973 by Norwegian philosopher Arne Naess in his 1973 article entitled “The Shallow and the Deep, Long-range Ecology Movement, a summary”. Among other inspirations, Naess’ outlook was deeply influenced by Baruch Spinoza’s vision of the the sacred in all things.

An Eco-philosophy

This ethical background lead Naess to suggest that the solution to ecological crisis lay in a radical change in perspective away from an anthropocentric world view, rather than technological fixes.

“All living beings have intrinsic value.” – Arne Naess

In North America, Aldo Leopold’s land ethic had a deep influence, extending moral consideration to soils, waters, and biotic communities. Ecophilosophy continued to develop in the 1970s and 80’s through the work of thinkers such as George Sessions coauthor with Arne Naess of the Deep Ecology Platform. Ecofeminist philosopher Val Plumwood enriched this tradition by revealing how hierarchical dualisms enable both environmental destruction and social oppression.

“Deep ecology asks for a radical rethinking of values, not only technology.” – Arne Naess

An engaged movement

“Care flows naturally if the self is widened and deepened so that protection of free nature is felt and conceived of as protection of our very selves.” - Arne Naess

Naess was also inspired by Mahatma Gandhi’s approach to non-violent activism - the Satyagraha or “truth holders” movement. With its foundations in the non-dual spiritual traditions of North India, these perspectives connected well with Spinoza’s almost pantheistic approach, and created a firm foundation of engagement in eco-philosophy to complement the underlying theory. In this way “Deep Ecology” also refers to an approach to environmentalism, echoing the use of “ecology” in the European context to refer to a social and political movement as well as a science of living systems. In demonstration of this aspect, Naess himself was involved in direct actions, for example in defence of Norways rivers from the damage wrought by damming for hydroelectric schemes.

A therapeutic process

“We must find and develop therapies which heal our relations with the widest community, that of all living beings.” – Arne Naess

From the outset, Naess also recognised the inner work required to bring about such a radical shift in perception. He called for a environmental movement aimed at “healing the perceived separation between humans and nature”, which he saw as the root cause of our ecological crisis. Beginning with the seminal book Thinking like a Mountain, Towards a Council of All Beings these group processes have been especially developed through the work of his coauthors on this book; Joanna Macy, John Seed, and Pat Fleming

A particularly potent model has become “The Work that Reconnects introduced in Joanna Macy’s book World as Lover, World as Self

Indigenous perspectives

Indigenous perspectives offer essential contributions often predating and informing contemporary movements. Robin Wall Kimmerer, Ailton Krenak, Tyson Yunkaporta, and Bayo Akomolafe demonstrate how traditional ecological knowledge represents sophisticated systems thinking developed over millennia of sustainable living, challenging colonial narratives that dismissed such wisdom as primitive.
