Query: Questions, questions.....

It is a fascinating book and the uniformity of reports about the spirit world from his patients is compelling. Yet, we know very little of Mr. Newton himself. He claims to be a PhD but where was he educated? If you do a search you'll come up with nothing (or at least I came up with nothing). He's said to have been on the faculty of higher educational institutions as a teacher. Which institutions and in what capacity? Again, a blank.Why isn't there transparency here? It's not like this information is somehow confidential or sensitive. All this is suspicious to me and smacks of someone with something to hide. And this taints the legitimacy of his research which remains uncorroborated. Until there are answers to these questions, just two stars from me.
