Alliance theory

The alliance theory, also known as the general theory of exchanges, is a structuralist method of studying kinship relations. It finds its origins in Claude Lévi-Strauss's Elementary Structures of Kinship (1949) and is in opposition to the functionalist theory of Radcliffe-Brown. Alliance theory has oriented most anthropological French works until the 1980s; its influences were felt in various fields, including psychoanalysis, philosophy and political philosophy.

Alliance theory has oriented most anthropological French works until the 1980s; its influences were felt in various fields, including psychoanalysis, philosophy and political philosophy. The hypothesis of a 'marriage-alliance' emerged in this frame, pointing out towards the necessary interdependence of various families and lineages. Marriages themselves are thus seen as a form of communication that anthropologists such as Lévi-Strauss, Louis Dumont or Rodney Needham have described. Alliance theory hence tries to understand the basic questions about inter-individual relations, or what constitutes society. Alliance theory is based on the incest taboo: according to it, only this universal prohibition of incest pushes human groups towards exogamy. Thus, inside a given society, certain categories of kin are forbidden to inter-marry. The incest taboo is thus a negative prescription; without it, nothing would push men to go searching for women outside their inner kinship circle, or vice versa. This theory echoes with Freud's Totem and Taboo (1913). But the incest taboo of alliance theory, in which one's daughter or sister is offered to someone outside a family circle, starts a circle of exchange of women: in return, the giver is entitled to a woman from the other's intimate kinship group. Thus the negative prescriptions of the prohibition have positive counterparts. The idea of the alliance theory is thus of a reciprocal or a generalized exchange which founds affinity. This global phenomenon takes the form of a 'circulation of women' which links together the various social groups in one whole: society. According to Lévi-Strauss's alliance theory, there are two different structural 'models' of marriage exchange. Either the women of ego's group are offered to another group 'explicitly defined' by social institutions: these are the 'elementary structures of kinship'. Or the group of possible spouses for the women in ego's group is 'indetermined and always open', to the exclusion, however, of certain kin-people (nuclear family, aunts, uncles...), as in the Western world. Lévi-Strauss call these latter 'complex structures of kinship'. Levi-Strauss' model attempted to offer a single explanation for cross-cousin marriage, sister-exchange, dual organisation and rules of exogamy. Marriage rules over time create social structures, as marriages are primarily forged between groups and not just between the two individuals involved. When groups exchange women on a regular basis they marry together, with each marriage creating a debtor/creditor relationship which must be balanced through the 'repayment' of wives, either directly or in the next generation. Levi-Strauss proposed that the initial motivation for the exchange of women was the incest taboo, which he deemed to be the beginning and essence of culture, as it was the first rule to check natural impulses; and secondarily the sexual division of labour. The former, by prescribing exogamy, creates a distinction between marriageable and tabooed women and thus necessitates a search for women outside one's own kin group ('marry out or die out'), which fosters exchange relationships with other groups; the latter creates a need for women to do 'women's tasks'. By necessitating wife-exchange arrangements, exogamy therefore promotes inter-group alliances and serves to form structures of social networks.
