Dianetics and Christian Science (If you're not familiar with it I'd suggest at least skimming the wikipedia article on Christian Science as their practices differ significantly from mainstream Christianity.) This isn't especially pressing but it piqued my curiosity nonetheless. In the 1950s Hubbard presented a book titled simply "Brainwashing" (Wiki, full text of the book), claimed to be recovered from the USSR as an example of brainwashing techniques used in Soviet-controlled areas. The book is pretty much universally considered to be Hubbard's own work. (it's one thing to brainwash people, but to write and sell a book explaining how you're doing it...) The following is taken from the Editor's notes: (I'm not sure if the Christian Scientists received their copy.) Searching through the text for "Dianetic," this same pairing comes up time and again - Dianetics and Christian Science as two threats to the Communist takeover; two strong, patriotic, American movements. What's the deal? The possibilities that come to mind are: 1. Hubbard was just throwing in a reference to another group in the hopes of making the Dianetics references stand out less. 2. Hubbard drew from Christian Science and considered it something worth bringing up as another positive group. Some practices of the Volunteer Ministers, for example, are basically faith healing. 3. Hubbard had some direct involvement with or connection to Christian Science. As I said, this isn't especially pressing, it just seemed odd.
