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.
