Here is a site that may help with the emailing. These are quotes from Eric Hoffer who wrote The True Believer back in 1950. He makes no mention of the JW's or WTBTS............ I doubt he was even aware of them.
What he wrote about was how mass movements have a lot of things in common and how they exercise control over their followers. Here is a free download: http://evelynbrooks.com/wp-content/uploads/2011/10/The_True_Believer_-_Eric_Hoffer.pdf
Here are a few sample quotes:
"An active mass movement rejects the present and centers it's interest on the future. It is from this attitude that it derives it's strength, for it can proceed recklessly with the present- with the health, wealth and lives of it's followers. But it must act as if it has already read the book of the future to the last word. Its doctrine is proclaimed as a key to that book.""All active mass movements strive, therefore, to interpose a fact-proof screen between the faithful and the realities of the world. They do this by claiming that the ultimate and absolute truth is already embodied in their doctrine and that there is no truth or certitude outside it. The facts on which the true believer bases his conclusions must not be derived from his experience or observation but from holy writ. "(p. 79)
