God Emperor of Dune is different. When you finish it, you realize that you’ve just absorbed a large amount of data from a great mind, so much that you need to go back and study the material to see what the author intended. Realize, though, that in this novel Frank Herbert was exploring some of the layers of Dune, Dune Messiah, and Children of Dune that he had already established, taking the dangers of government and organized religion to new levels, merging them, and extrapolating to an extreme, providing a scenario of what it might be like if a holy tyrant led humanity and if that despot could not die. The stakes could not be any higher. And what a fantastic concept, combining human flesh with supernatural elements of nature to create a godhead. A frightening notion—and even more terrifying than the dangers of following a charismatic leader that Frank Herbert wrote about so eloquently in the second and third books of the series.

It is also interesting to note that Frank Herbert often wrote about beings with godlike powers, entities that took on differing forms. In Destination: Void and The Jesus Incident (cowritten with Bill Ransom), the entity is a supercomputer. In Whipping Star, it is a celestial body, a star. In The Godmakers and Dune, the gods are in human form. In God Emperor of Dune, the entity is part mysterious sandworm, part human, a creature that contains a vast storehouse of knowledge.

The God Emperor, Leto Atreides II, is one of the most unusual characters in the annals of science fiction. He has lived for more than 3,500 years and possesses a wisdom that spans time and space. He seems capable of living forever, of leading humankind into the eternal future. For millennia after the events in the novel Dune, Leto has enforced a peace—a “Golden Path”—under which he has ensured the continued existence of the human species. As Leto puts it, “The Golden Path… is the survival of humankind, nothing more nor less.” But Frank Herbert, who saw the dark side of the hero, also saw the dark side of the perfect civilization. He called this way of thinking “myth-busting” or seeing the “dystopia in the utopia.” As a newspaper reporter for many years, he often turned over stones to see what would scurry out. At the University of Washington in Seattle, he taught a political science class about shattering the myth structures under which we live. A modern-day Socrates, he tore into what he called “unexamined linguistic and cultural assumptions.”

My father knew how to do his research. Back in the 1950s, he was a speechwriter for a U.S. senator and worked in Washington, D.C. With C-9 security clearance, Frank Herbert had special access to the Legislative Reference Service of the Library of Congress, through which he could use virtually any document or book in the vast library. He just got on the telephone, ordered what he wanted, and presently it arrived in a cart, with blue book-marks designating the pages that were of interest to him. Notes were included on material available at other government facilities, including the National Archives and the Army Corps of Engineers. If he wanted any of the additional materials, he simply ordered them through the Library of Congress and soon they were in front of him.
