Although he is known primarily as the inventor of the phrase deep ecology, Norwegian philosopher Arne Naess's thoughts and approaches have wrestled with all the major events of our times. From the study of psychoanalysis in Freud's Vienna, through the mid-century hardening of ideologies, to the most recent decades with the emergence of ecology as a political force, he has espoused precise and clear thinking in the face of great contemporary dilemmas. Rothenberg presents the grand old man of natural philosophy in his own words. What emerges is the personal vision of a life imbued with ecology.
