Book excerpt: The professionalization of anthropology through practical engagement is a major force underpinning the reformulations of the nature of the anthropological project. It is therefore imperative that anthropologists critically explore the conditions of their practices, to determine the difficulties and limitations to their ethical practice. These essays examine the application of expert knowledge in fields where there is the expectation of considerable cultural, social, and political consequence for human populations as a result of state, corporate, or non-governmental re-organization.
