A heads up:
Michael Hogue, on the faculty at Meadville Lombard Seminary in Chicago, has just (this week!) published a book,
The Promise of Religious Naturalism, that presents and analyzes the thinking of Loyal Rue, Donald Crosby, Jerome Stone, and Ursula Goodenough as well as his own. I’ve read several drafts and it’s excellent.
