It's a joke, really it is!
Harlan Ellison interviewed by (now defunked Wings Magazine)
Ellison: Scientology is bullshit! Man, I was there the night L. Ron Hubbard invented it, for Christ Sakes!
I was sitting in a room with L. Ron Hubbard and a bunch of other science fiction writers. L. Ron Hubbard was famous among science fiction writers because he was the first one to have an electric typewriter.
Wings: He claimed to have written Dianetics in a weekend, and nobody can deny it.
Ellison: That's true. He wrote Dianetics in one weekend, and you know how he used to write? He used to take a roll of white paper, like paper you wrap fish in. He had it on the wall, and he would roll it into the typewriter and he would begin typing. When he was done, he would tear it off and leave it as one whole long novel.
We were sitting around one night... who else was there? Alfred Bester, and Cyril Kornbluth, and Lester Del Rey, and Ron Hubbard, who was making a penny a word, and had been for years. And he said "This bullshit's got to stop!" He says, "I gotta get money." He says, "I want to get rich".
Wings: He is also supposed to have said on that same night: "The question is not how to make a million dollars, but how to keep it."
Ellison: Right. And somebody said, "why don't you invent a new religion? They're always big." We were clowning! You know, "Become Elmer Gantry! You'll make a fortune!" He says, "I'm going to do it." Sat down, stole a little bit from Freud, stole a little bit from Jung, a little bit from Alder, a little bit of encounter therapy, pre-Janov Primal Screaming, took all that bullshit, threw it all together, invented a few new words, because he was a science fiction writer, you know, "engrams" and "regression", all that bullshit. And then he conned John Campbell, who was crazy as a thousand battlefields. I mean, he believed any goddamned thing. He really believed blacks were inferior. I mean he really believed that. He was also very nervous when I was in his office because I was a Jew. You know, he was afraid maybe I would spring horns or something.
Anyhow, the way he conned John was that he had J. A. Winter, who was a doctor, who was a close friend of John's, and he got him to run this article on Dianetics, the new science of mental health.
Wings: Dianometry was the first article, I believe.
Ellison: Right. And science fiction fans will go for any goddamm thing. They'll believe anything, man, they will believe in the abominable snowman and the Bermuda Triangle, in Pyramid Power, in EST, in Scientology, in the Second Coming, they'll believe in any goddamm thing, they don't give a shit. They go to see Star Wars; they think it is for real!
