L. Ron Hubbard was a hack SF writer in the 40s and 50s. He wrote typical imaginative adventure based SF without much depth or characterization. He would be forgotten today if he hadn’t invented Dianetics. I read the original Dianetics in Astounding Science Fiction, and I was not impressed. Somehow this pseudo scientific alternative to psychoanalysis has turned into a religion, which I know very little about. I do know enough to be very frightened of a man that might be President, who thinks Battlefield Earth is a good book.
