The contributions in this volume address a number of interconnected questions regarding the ethics of intervention (and non-intervention). What kind of problem is intervention? What moral dilemmas are raised by, and ethical justifications offered for, acts of (non)intervention? What are the practical implications and limitations of such justifications? Answers to these questions can be developed at a number of levels and from a number of perspectives. Intervention can be discussed in legal terms, in political terms, in anthropological or social psychological terms, in normative terms or, more likely, in some combination of these and other frameworks.
