Arne Naess, widely regarded as the foremost Norwegian philosopher and one of the most influential intellectuals of the twentieth century. Naess was an inspirational figure within the environmental movement of the late twentieth century. He is perhaps most known as the person who coined the term “deep ecology,” an approach to environmental problems that looks for its roots deep in the structure of our western society and the worldviews that guide it. He later preferred the term “ecosophy”, which we use here to distinguish between the philosophy underlying Deep Ecology, and the group practices themselves.
