Human Cognitive Advances Theme Analysis

Dune is the epic tale of the young nobleman Paul Atreides and his ascendancy to power in a futuristic world characterized by intergalactic human habitation. In his narrative, author Frank Herbert shows a preoccupation with the future development of the human mind. This was an unusual priority for science fiction of the time, which tended to focus on technological futures rather than advances in human psychology. While Dune includes some futuristic technologies such as laser shields and ornithopters, it is the cognitive abilities of humans that best showcase Herbert’s creativity. In particular, Herbert uses the future cognitive and psychic abilities of Mentats and Bene Gesserit sisters to demonstrate his belief that humanity’s cultural evolution will hinge more on cognitive rather than technological changes.

The Bene Gesserit order is a mysterious sisterhood who favor psychological manipulation for worldly influence, and they are responsible for many of Dune’s political occurrences. The group taps into many forms of mental conditioning. This includes a female collective unconscious that arises from shared genetic memories, using “the weirding way” to exert psychic control over others, and using mental control to override physical stresses such as pain. The sisterhood is also responsible for 40 generations of genetic bloodline control aimed at producing the prophesized Kwisatz Haderach, a powerful being capable of shaping humanity’s future prosperity. Thus, the Bene Gesserit’s complex cognitive talents and missions are critical for human evolution in Herbert’s novel.

Mentats are individuals possessing extreme analytical and processing abilities who symbolically function to replace computers Herbert’s story. The world of Dune has banned any “thinking machines” made “in the likeness of man,” and therefore there are no digital machines such as computers. Instead, Mentats are humans who can process enormous amounts of data to make complex and insightful decisions. Often employed as political aides to noble families, Mentats symbolically function to highlight Herbert’s distrust of exclusively technological societal advances. Herbert’s dislike of technological evolution is also represented by the ability of the sandworms on planet Arrakis to render electrical and metal technologies useless.

The culmination of Herbert’s desire to see humanity evolve cognitively rather than technologically is reflected in the development of Dune’s protagonist, Paul Atreides. With the aid of spice, Paul transforms into the Kwisatz Haderach “who could indeed see the future.” As this figure, he is the culmination of the Bene Gesserit’s 10,000-year-old genetic breeding program and can access the sisterhood’s collective memories. He learns to practice “mind-body” meditation from his Bene Gesserit mother, Lady Jessica, to relieve personal stresses. He also trains his Fremen army in the Bene Gesserit “weirding way” so that they become more lethal soldiers. Paul also benefits from the childhood Mentat training he received from Thufir Hawat, who was Duke Leto’s talented Mentat. Hawat was able to train the young Atreides extensively in political and military strategy, which ultimately helps Paul capitalize on circumstances that link him to the Fremen’s prophesized messiah “Lisan al-Gaib.” This, in turn, sets Paul up for his triumph over the Padishah Emperor and Harkonnens with the support of the Fremen army. Thus, the mental abilities of the Bene Gesserit and Mentats shape the cognitive makeup of Paul Atreides, who is Frank Herbert’s ultimate depiction of human potential in Dune. Across his writing, Herbert was invested in exploring the evolution of the human mind over time; Paul’s development is a transformational point in Herbert’s imagined future of Dune due to Paul’s unique cognitive abilities.
