The Elementary Structures of Kinship was published the next year and quickly came to be regarded as one of the most important anthropological works on kinship. It was even reviewed favorably by Simone de Beauvoir, who viewed it as an important statement of the position of women in non-Western cultures. A play on the title of Durkheim's famous Elementary Forms of the Religious Life, Elementary Structures re-examined how people organized their families by examining the logical structures that underlay relationships rather than their contents. While British anthropologists such as Alfred Reginald Radcliffe-Brown argued that kinship was based on descent from a common ancestor, Lévi-Strauss argued that kinship was based on the alliance between two families that formed when women from one group married men from another.[19]
