Abstract
In this paper, an ecologically extended ethic of authenticity is developed in dialogue with the Norwegian environmentalist Arne Naess and the Japanese ethicist Watsuji Tetsurō. More specifically, Naess’s concept of Self-realization is supplemented and supported with Watsuji’s ethic of authenticity and phenomenology of climate. And the ecological potential of Watsuji’s thought is realized in relation to Naess’s ideas of human responsibility and symbiosis. After establishing an ecologically extended ethic of authenticity, the practical application of this concept is then demonstrated in relation to satoyama and the preservation of nature in Japan. Whilst the intended outcome is to develop an ecologically extended ethic of authenticity, a secondary aim is to illustrate the benefit and importance of cross-cultural dialogue to advance philosophical thought and understanding.
