Tim O'Reilly, of the famous publishers, interviewed and later befriended Herbert while writing his 1981 book on the author, Frank Herbert. It covers a lot of the themes of the linked essay in an effort to explore the origin and meaning of the Dune trilogy, as it was then.
The book is freely available on oreilly.com[1] and likely worth a look for anyone interested in TFA.
For example, O'Reilly claims "in writing about the mystique of the superhero, Herbert himself was prey to it" quoting Analog editor John Campbell's rejection letter for Dune Messiah: "science-fictioneers [...] want heroes—not anti-heroes. They want stories of strong men who exert themselves, inspire others, and make a monkey's uncle out of malign fates! As Paul did in Dune —not as he fails completely to do in The Messiah"
Campbell misses the point, O'Reilly says, " that Herbert deliberately looked for this reaction from his readers. To Herbert, the hero mystique is symptomatic of a deadly pathology in contemporary society, a compulsive yearning for easy answers. As long as men are looking for simple solutions to their problems, they will give over their ability to think for themselves to the first person who comes along and promises a solution. The Dune trilogy is an attempt to unveil that pattern and, in some small part, to change it."[2]
