This book is framed as "case studies" voted on by a "jury" consisting of a Catholic, a Mormon, a Southern Baptist, a Jew, a Muslim, and an atheist. Once they've voted, an agnostic, and only the agnostic, is allowed to "comment." All of these individuals are nameless.
Let's be clear. The agnostic gets to comment on what the "jurors" say and what their thought process must have been, while the reader is not allowed to hear the voices of the actual jurors.
It's important to note that Jack Gage is not a scientist, and does not appear to have much if any scientific education. He's a businessman and a lawyer, and apparently of the school of thought that says that if you're a successful businessman and a lawyer, you're an expert on everything.
