The assumption that humans exist within an essentially impermanent universe, taken as an operational precept, demands that the intellect become a totally aware balancing instrument. But the intellect cannot react thus without involving the entire organism. Such an organism may be recognized by its burning, driving behavior. And thus it is with a society treated as organism. But here we encounter an old inertia. Societies move to the goading of ancient, reactive impulses. They demand permanence. Any attempt to display the universe of impermanence arouses rejection patterns, fear, anger, and despair. Then how do we explain the acceptance of prescience? Simply: the giver of prescient visions, because he speaks of an absolute (permanent) realization, may be greeted with joy by humankind even while predicting the most dire events.
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 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.
