The life of a single human, as the life of a family or an entire people, persists as memory. My people must come to see this as part of their maturing process. They are people as organism, and in this persistent memory they store more and more experiences in a subliminal reservoir. Humankind hopes to call upon this material if it is needed for a changing universe. But much that is stored can be lost in that chance play of accident which we call "fate." Much may not be integrated into evolutionary relationships, and thus many may not be evaluated and keyed into activity by those ongoing environmental changes which inflict themselves upon flesh. The species can forget! This is the special value of the Kwisatz Haderach which the Bene Gesserits never suspected: the Kwisatz Haderach cannot forget.

The one-eyed view of our universe says you must not look far afield for problems. Such problems may never arrive. Instead, tend to the wolf within your fences. The packs ranging outside may not even exist.
One of us had to accept the agony, and he was always the stronger.
The body of Muad'dib is a dry shell like that abandoned by an insect. He mastered the inner world while holding the outer in contempt, and this led to catastrophe. He mastered the outer world while excluding the inner world, and this delivered his decendants to the demons. The Golden Elixer will vanish from Dune, yet Muad'dib's seed goes on, and his water moves our universe.
