Campbell's editorials in each issue of Astounding were some of the best writing I've ever read. My dad subscribed to ASF and I went back and read every issue from 1948 until way past Campbell's death. At first, Campbell was very supportive of this new idea that possibly could unlock the secrets of the human mind. As time went on, he became more skeptical and finally after a couple of years came to the conclusion that Hubbard was a fine science fiction writer, but that Scientology was bunk.
A fine science-fiction writer? Have you actually read any of Hubbie's crap? I could eat a bowl of alphabet cereal and crap a better science-fiction novel than that freak could have ever dreamed of penning.
