but if he was at all inspired by the occult, his studies would have led to the development of an organization like the Theosophical Society, not the Watch Tower Bible and Tract Society.
Just because some one says it it a book that supports your point of view doesn't make it correct. This particular conclusion sounds like a supposition by the author and contains no direct support in the following information that I saw. It is still very possible, in fact probable, based on the symbology of early publications that he was in fact influenced by occult teachings. Although he may have simpley coopted the symbology for his own personal philosophy, they symbols still have a very clear origin and, in the case of freemasonery as an example, still in use.
The fact that the WTS has refined both the look and substance of thier belief structure since, does not support the idea of being Gods annoited voice. Especialy when compared to how all religions evolve in their look and dogma over time. In fact most of the older more well established religions have a MUCH more stable system of belief and changes, when they occur, do so over a longer period of time than in the WTS. It does however support the idea that they are no more than a organization of men and respond in a similar fashion to other organizations like them.
