On spiritual and social identity Watts felt that absolute morality had nothing to do with the fundamental realization of one's deep spiritual identity. He advocated social rather than personal ethics. In his writings, Watts was increasingly concerned with ethics applied to relations between humanity and the natural environment and between governments and citizens. He wrote out of an appreciation of a racially and culturally diverse social landscape. At the same time, he favored representative government rather than direct democracy (which he felt could readily degenerate into mob rule). He often said that he wished to act as a bridge between the ancient and the modern, between East and West, and between culture and nature. Watts led some tours for Westerners to the Buddhist temples of Japan. He also studied some movements from the traditional Chinese martial art T'ai Chi Ch'uan, with an Asian colleague, Al Chung-liang Huang. Watts lived his later years at times on a houseboat in Sausalito on San Francisco Bay and at times in a secluded cabin on Mount Tamalpais. Laden with social and financial responsibilities, he struggled increasingly with alcohol addiction, which probably shortened his life.[3] In October 1973 he returned from an exhausting European lecture tour. Watts died of heart failure in his sleep at his home on Mt. Tamalpais the following month at the age of 58.
