This felicitation volume for Josephus D.M. Platenkamp brings some central concerns of anthropology into focus: social morphology, exchange, cosmology, history and practical applications. Ranging across several disciplines and continents, but with a preference for Southeast Asia, the contributions look at a common approach that unites these diverse themes. In this view, the most constitutive relationships of society are based on exchange. Exchange and ritual articulate central values of a society, thus appearing as parts in relationship to a whole. These relationships encompass both human and non-human beings, the social and the cosmological domain. Thus, the study of these subject issues merges into a single project.
