Abstract
The heroes and villains of the Dune universe live in a world where violent conflict is an inevitable and necessary part of life. In the brutal worlds of the galactic Imperium and the Arrakeen desert wilderness, inquiry, perception, and logic are no longer tools of scientific truth‐seeking, but have become weapons in a war between minds as sharp as the cutting edge of a crysknife. The inquiries of Dune's characters don't follow the logic of scientific discovery but instead the wartime logic of advantage. The conflict between House Atreides and House Harkonnen stretches back to the earliest days of the empire. In most cases, accurate information would still be preferred, but in this case rapidly formed beliefs that enable a timely decision are ultimately more useful than carefully verified knowledge. The grim necessities of kanly force Dune's characters to value the utility of knowledge over its truthfulness.
