Two Sisters and Their Mother The Anthropology of Incest

The author explores the taboo regarding the incest of the second type which concerns blood relations of a same sex who share the same sexual partner. She makes us understand that the categories which we use to determine what is incestuous and what is not are founded on representations of the identical and the different, which are themselves derived from the difference in the sexes.
