Final Blackout is considered Lron’s best SF writing. Dianetics used re-cast 1940’s computer jargon mated to psycholocial anyalysis he never gave credit for–what’s known as “ab-reaction psychology”, which is doubly tragi-comic considering Scientology vendetta against any legitimate psychology or psychiatry.
A GREAT period piece of writing (early 50’s) about the transition period of Dianetics into Scientology is Martin Gardner’s In the Name of Science–an entire chapter is dedicated to Dianetics of the time, though the true weirdness & occultism had yet to be exposed
