overconfidence and the Fremen's capacity for self-sacrifice. The Fremen put the community before themselves in every instance, while the world outside wallows in luxury at the expense of others. The decline and long peace of the Empire sets the stage for revolution and renewal by genetic mixing of successful and unsuccessful groups through war, a process culminating in the Jihad led by Paul Atreides, described by Herbert as depicting "war as a collective orgasm" (drawing on Norman Walter's 1950 The Sexual Cycle of Human Warfare). These themes reappear in God Emperor of Dune Scattering and Leto II's all-female Fish Speaker army. Heroism Brian Herbert wrote that "Dune is a modern-day conglomeration of familiar myths, a tale in which great sandworms guard a precious treasure of melange...[that] resembles the myth described by an unknown English poet in Beowulf, the compelling tale of a fearsome fire dragon who guarded a great treasure hoard in a lair under cliffs". Paul's rise to superhuman status follows the hero's journey template; after unfortunate circumstances are forced onto him, he suffers a long period of hardship and exile, and finally confronts and defeats the source of evil in his tale. As such, Dune is representative of a general trend beginning in 1960s American science fiction in that it features a character who attains godlike status through scientific means. Frank Herbert said in 1979, "The bottom line of the Dune trilogy is: beware of heroes. Much better [to] rely on your own judgment, and your own mistakes." He wrote in 1985, "Dune was aimed at this whole idea of the infallible leader because my view of history says that mistakes made by a leader (or made in a leader's name) are amplified by the numbers who follow without question." Juan A. Prieto-Pablos says Herbert achieves a new typology with Paul's superpowers, differentiating the heroes of Dune from earlier heroes such as Superman, van Vogt's Gilbert Gosseyn and Henry Kuttner's telepaths. Unlike previous superheroes who acquire their powers suddenly and accidentally, Paul's are the result of "painful and slow personal progress." And unlike other superheroes of the 1960s—who are the exception among ordinary people in their respective worlds—Herbert's characters grow their powers through "the application of mystical philosophies and techniques." For Herbert, the ordinary person can develop incredible fighting skills (Fremen, Swordmasters of Ginaz and Sardaukar) or mental abilities (Bene Gesserit, Mentats, Spacing Guild Navigators).
