Exchanges are fundamental to human societies. The authors show that the study of exchanges not only serves as a key to understanding particular societies as totalities but also helps to frame a comparative mode of analysis expressed in terms of a hierarchy of values. Starting with a comparative analysis of the different vocabularies used when dealing with exchange, the authors go on to provide a detailed account of how each society''s exchanges form a genuine value-oriented system. Their conclusions shed light on important issues in anthropology such as the difference between subject and object; the construction of the person in the matrix of social relations; and the contrast between ''socio-cosmic'' systems and other societies which recognize a universal term of reference beyond their community.
