Definition of "ecosophy"

[…] ecosophy argues that an individual should act in such a way as to “do as little harm as possible.” The “oath” of those committed to ecosophy closely parallels that of medical doctors: Above all else do no harm.

His ideas on ecology and ecosophy were developed in numerous books and articles, notably “Freedom, Emotion and Self-Subsistence” (1975), “Ecology, Community and Lifestyle” (1989) and “Life’s Philosophy: Reason and Feeling in a Deeper World” (2002).
