This collection of 10 contributed essays is the first to explicitly address the question of ritual efficacy. The authors do not aspire to answer the question 'how do rituals work?' in a simplistic fashion, but rather to show how complex the question is. While some contributors do indeed advance a particular theory of ritual efficacy, others ask whether the question makes any sense at all, and most show how complex it is by referring to the sociocultural environmentin which it is posed, since the answer depends on who is asking the question, and what criteria they use to evaluate the efficacy of ritual.
