That's what I'd like a source for.
Hubbard took a mishmash of things that people did or had done to improve their condition, from talk therapy to various other techniques to improve on's communication skills, to others to improve ones ability to observe realty more fully to techniques to reduce the impact of environmental toxins.
He organized them into a path that many have found helpful.
Yeah he's a fraud, he claimed every single one of them as his own independent invention or discovery.
Yeah he wasn't a nice man.
Yeah he abused a LOT of people.
Worse he set up a system to use a workable technology to abuse people en masse.
And he didn't have the sense to put in safeguards to insure it wasn't used against him.
He died in isolation under the care of the very people who would vastly benefit from his demise.
Cerebral hemorrhage, or so it was said, no autopsy, prompt cremation. Dr Gene Denk had him on Coumadin, a blood thinning agent also sold as a rat poison under the brand name warfarin. It causes death by hemorrhage and internal bleeding.
I knew Dr Denk, and I doubt very seriously that he caused Hubbard's death, but it would have been so very very easy for anyone in his retenue to deliberately or accidentally give him an overdose.
That being said, the tech itself works, like any other tool, it can be used for good or evil. The current ownership chose poorly.
“but you asserted that the tech didn’t work”
you’re confusing me with some other poster - i made no such assertion.
