The old JW books from the 40's are really worth reading- hard to believe, but it's true, lol. I bought one and read it a couple of years ago, and it made me happy as I was finally able to see a pattern in the JW beliefs- how it all seems to make sense at the time; but 10 or 20 years later it's no longer relevant or even possible- so it all keeps changing. The PDF's are great, but there's nothing like the real thing, lol.
