"The paper emphasizes that ideas about masturbation are crucial to understanding any societal attitudes toward sex. It examines attitudes to masturbation in ancient Egypt, Tigris Euphrates Valley, India, and China. It looks at Biblical views and their misinterpretations and at the Greek and Roman descriptions of masturbatory practices. Key to the development of western attitudes was the Augustinian version of sex which was influenced by Augustine's personal background in Manichaeanism, a religion which was based on ancient Persian beliefs. The Augustinian view of all non-procreative sex as a sin was carried over into medicine in the eighteenth century which changed sins into pathologies."
