Ji'e'toh is a concept from the Dune universe, created by Frank Herbert. It refers to a system of ethics and social responsibility among the Fremen, the desert-dwelling people of the planet Arrakis. Ji'e'toh emphasizes the importance of community, loyalty, and the interconnectedness of individuals within their society. In practice, Ji'e'toh guides the Fremen in their relationships and decision-making, ensuring that actions benefit the group as a whole. This principle is crucial for survival in the harsh environment of Arrakis, where cooperation and mutual support are essential for enduring the challenges of their world.
