Chapter 8 Summary: “Internal Lines”

Contrary to widespread belief, pollution has much to do with morals and ethics in primitive societies. Pollution rules do not always correspond exactly with moral rules; they highlight only “a small aspect of morally disapproved behavior” (160). Still, there is a definite relationship. Among the relevant moral situations are incest, homicide, adultery, filial disrespect, and etiquette between husband and wife and in-laws. Ritual sacrifices are often necessary to make reparation for offenses. Such rituals “can help to erase memory of the wrong and encourage the growth of right feeling” (168). If the ritual is not performed, danger is believed to fall upon the guilty party or even upon innocent people in his circle.

Chapter 8 Analysis

Here Douglas attempts to show that pollution has much to do with ethics and morality, contrary to what many early anthropologists believed. She cites several examples of how pollution may support moral values in primitive societies. The Nuer tribe in Africa believes that committing incest brings misfortune in the form of skin disease. In many societies, when a man's wife commits adultery, various persons are believed to suffer as a result: It may be the woman, her husband, the adulterer, or the couples’ children.
