This seemed like a book unsure about what it really wanted to be. Of course, that can be put another way, to say it is a book that does not settle with current divisions of the field or discipline and works across the boundaries. I will grant that partly, but I am not wholly convinced. What begins as apparently a critical and constructive work on theory of religion and method in the study of religion turns into an exercise in theology of a sort, but more about other books than about "God" or other candidates for ultimacy. It became less critical and much more cryptical.
(A day later, let me try restating this again: Perhaps the unclarity is more with regard to the intended audience. Initially, it purports to be a book that might be relevant to the entire field of the study of religion, but then it turns into what appears to be an exercise in confessional (a)theology or "minimal theology" or "psychotheology," depending on which of his influences he is discussing. Then the jargon is thick and the discourse not very accessible to a non-initiate like me. There is development through those chapters, but it is hard to discern -- too easy to miss the territory for his different maps of choice.)
The best passage, I thought, was this: "It is perhaps nowhere more evident than in today's study of religion that we academics have failed to take seriously enough Nietzsche's 'yes-saying.' We know how to say no, to decode and demystify, even if, not knowing how to affirm, we are not always able to explain why we should demystify." (236) I think this is right on. But after his initial critique of "locativist" criticism in the study of religion in the first couple of chapters, Roberts doesn't really say a 'yes,' so much as a "now let me talk this other way" - a way which, it seemed to me much of the time, "locativists" could have a field day criticizing. I guess there wasn't enough dialectical connection between his critical and constructive work for me, and the construction just seemed a little arbitrary as a result.
