Homosexuality, Heterosexuality, Perversion is the work of a (now deceased) practicing psychoanalyst whose ideas regarding homosexuality and perversions were shaped by his experience doing ethnographic field research in diverse primitive cultures of West Africa, New Guinea, and South America. These investigations outside of the psychoanalytic consulting room compelled Morgenthaler to consider the influence of social and cultural values on psychoanalytic observation and technique. His book is based on lectures and articles written from 1960 to 1983 in which he developed a metapsychology of perversion that was strongly influenced by what has been termed ethnopsychoanalytic research. The relationship of individual development and intrapsychic structure formation to the variable demands of differing sociocultural environments provided an important adaptational frame of reference for his thinking about sexuality. He considered societal variables to be especially pertinent to the study of the varieties of sexual experience and to judgments about perverse sexuality. From
