As a whole this volume offers much material for reflection. It certainly introduces many voices new to the media and religion discussions and it presents enough case study data to inform its theoretical proposals. It certainly indicates a growing maturity of the media and religion area. Each essay has its own notes and reference list. The book features an index. —Paul A. Soukup, S.J.

Anyone looking for a typical summary text of various communication theories will find this book puzzling—certainly not what the typical reader expected. But the book more than rewards a careful reading, for it introduces a much more complete understanding of communication, particularly in the face of the empirical studies and theories of communication developed through the social science methods of the past 40 years. The more ancient path to knowledge works its way through rhetoric, and various people trained in rhetoric raise questions about effects: not just the effects from efficient cause, but the more profound effects stemming from formal and final cause. In all this, the lodestar for the McLuhans lies in formal cause. Understand that, and one has a good grasp of both communication and of Marshall McLuhan’s writings. The volume consists of 16 chapters plus five appendices, most of them reprinted from the writings of the McLuhans. The original work comes from Eric McLuhan and more directly addresses the idea of the theories of communication as found in various key figures of Western learning:...
