BUTLERIAN JIHAD (“THE GREAT REVOLT”)

[…]

“With Jehanne [Butler] gone, the Jihad had no higher objective than the destruction of the computers. It was successful beyond expectation in that aim, and the movement dwindled as it found fewer and fewer targets for its wrath. In its wake, or, to continue Sheivvun’s metaphor, as it ebbed, it left both poverty and opportunity: it burned a hatred and fear of thinking machines so deeply into the human psyche that one wonders if that would has yet completely healed.”

“Then came the Butlerian Jihad, causing generations of chaos. The god of machine-logic was overthrown among the masses and a new concept was raised: “Man may not be replaced.” The B.G.[Bene Gesserit]-sponsored campaign removed from men a rival power of futurological control.”
