Treatise on the Law of Indirect and Collateral Evidence Book

I just randomly picked this book up in the library as I knew next to nothing about the wicca faith/traditions and it was a small enough book. It was interesting to go through the actual rede and there were a few interesting bits of information about the wiccan faith.
On the whole, however, and despite his own protestations, the author is very opinionated and some of the "interpretation" of the separate couplets of the rede were unnecessarily drawn out and downright rambling. I skimmed quite a few pages and ended up skipping a few more for good measure.
Still, I guess the book has given me a general idea about the wiccan belief system, but if I decide to read more in future, I will definitely look for books by other authors.
