I thought we had discussed this book here once, although I have not read it, but I can't find any mention of it. Anyway, here is an interesting discussion of it by Francesca Murphy at Public Discourse. She says it is
a liminal secular-religious book. It is on the border between the two, broad enough on both sides to pose a challenge in either direction. It challenges its secular readers to have a deep enough conception of the secular to encompass dying for the sake of freedom. It challenges its religious readers to deepen their pieties sufficiently to encompass the aspiration for freedom that is written in the human frame.
Well, I don't know about that, obviously, since I haven't read it. But apart from the identity of the author, this strikes me as an interesting indirect comment on the argument that's been going on among conservatives for a while now: is the liberal (and effectively secular) tradition a good thing or a bad thing, especially as it relates to religion? And in either case what are its prospects?
