I had the book dianetics................and I must say that it is the one and only book that I just could not finish reading. It is wierd/sick stuff..........made no sense to me and was boring beyond belief.
I had exactly the opposite experience. It just clicked with me. I read it in one night, and was taking my first course the very next week end.
YMMV...
When I was in college, my mother borrowed it from the library and we both read through it, or for me parts of it, and laughed, too. It was wierd. Strange. Easy to see how people can associate it with sci fi or certain psychology ideas. But again, as a student of psych at the time, I thought his psych ideas were borrowed, and that he didn't necessarily understand what he was writing about. I thought it was boring, too.
