It’s crank.

You should be able to determine this yourself.

Apply basic critical thinking skills.

Then you’d find:

That author has no relevant skills or degrees, and no peer reviewed literature in either field, and nothing on this point. And that book is a self-published fancy chasing an implausible fantasy.

You therefore have no reason to spend even a minute more of your time on it. Move on. And remember you live in the post-truth era and thus have to critically vet everything before giving it your attention. Because every crank in the world wants your attention. And you have a limited amount of it, which you should be spending on quality sources of information instead.

There was a kind of trend then to publish scandalous challenges to religious authority.

But whether anything in them is still useful, an expert would have to go in them and find it. Odds are, there won’t be much that isn’t already in current sources, so the cost-benefit ratio is too high to bother with. But all are welcome to see if they can pull anything novel out of there that holds up.

Oh thanks! I garbled Decoding and Prince. Fixed.

Thanks for your book recommendation series! I always look forward to your suggestions.
