I'm still curious about just how big a deal it was, that many people independently came to the same "cognition", even just theoretically. Was it really so independent, or was the Clear cognition all but spoon-fed to everyone by the materials?
Pre-internet it was independent. It was a huge (declarable) offense for anyone to spoon-feed the cognition to anyone and it just wasn't done. I can't say that it never ever happened, but it certainly wasn't common at all and the prohibition wasn't given mere lip-service nudge nudge.
