Unless ye believe ye shall not understand. -- St Augustine
I was born a thousand years ago, born in the culture of bows and arrows ... born in an age when people loved the things of nature and spoke to it as though it had a soul. -- Chief Dan George
The woods were formerly temples of the deities, and even now simple country folk dedicate a tall tree to a God with the ritual of olden times; and we adore sacred groves and the very silence that reigns in them no less devoutly than images that gleam in gold and ivory. -- Pliny
In the stillness of the mighty woods, man is made aware of the divine. -- Richard St Barbe Baker

Ecology and spirituality are fundamentally connected, because deep ecological awareness, ultimately, is spiritual awareness. -- Fritjof Capra
Every social transformation ... has rested on a new metaphysical and ideological base; or rather, upon deeper stirrings and intuitions whose rationalised expression takes the form of a new picture of the cosmos and the nature of man. -- Lewis Mumford
... there is reason to hope that the ecology-based revitalist movements of the future will seek to achieve their ends in the true Gandhian tradition. It could be that Deep Ecology, with its ethical and metaphysical preoccupations, might well develop into such a movement. -- Edward Goldsmith
The main hope for changing humanity's present course may lie ... in the development of a world view drawn partly from ecological principles - in the so-called deep ecology movement. -- Paul Ehrlich
The religious behaviour of man contributes to maintaining the sanctity of the world. -- Mircea Eliade
The Norwegian philosopher Arne Naess coined the phrase deep ecology to describe deep ecological awareness. Deep ecology is the foundation of a branch of philosophy known as ecophilosophy, Arne Naess prefers the term ecosophy, that deals with the ethics of Gaia.
Fritjof Capra defined deep ecology by contrasting it with shallow ecology and showing that it is a network concept:
Shallow ecology in anthropocentric, or human-centred. It views humans as above or outside of nature, as the source of all value, and ascribes only instrumental, or 'use', value to nature. Deep ecology does not separate humans - or anything else - from the natural environment. It does see the world not as a collection of isolated objects but as a network of phenomena that are fundamentally interconnected and interdependent. Deep ecology recognizes the intrinsic value of all living beings and views human beings as just one particular strand in the web of life.
