Drengson is the Associate Editor of the ten volume Selected Works of Arne Naess (SWAN) published in 2005 by Springer. In 1983, he founded the now online magazine Trumpeter: Journal of Ecosophy and, later, Ecoforestry. Until his death in 2009, Bill Devall was well-known as both theorist and activist in the environmental movement. Together, they wrote this introduction to the life of Arne Naess and his ecophilosophical reflections in particular. They also refer to Naess’s own life’s philosophy, called Ecosophy T.
