Two salient features of the Space Ark's unique social institutions stand out above the myth and fairytale of our ancestors, however. The first is the fabled story of the Mutant-makers, and when one studies the conditions surrounding this phenomenon, the fabled story becomes cold scientific fact. On a giant balanced-terrarium of a ship which was largely automatic, seemingly isolated forever in the vastnesses of interstellar space, our ancestors lacked even a modicum of external challenge. They thus had to create their own artificial stimuli or face an inevitable retreat down the ladder of decadence to barbarism. It appears that for a time they went too far: they created mutants. These in turn gave rise to a rigid caste-system on the Ark, a system which afforded an extreme in internal challenges and responses.
The second salient feature of the Space Ark's social institutions was its favoring of the biolo-mental sciences over the chemi-physical sciences. This, again, proves to be an inevitable by-product of the Space Ark's static environment. No physical world existed: physics became a useless dogma, a meaningless jumble of terms which bore no semantic relation to the world-at-large. On the other hand, the Space Ark was a universe of introversion. The biolo-mental sciences leaped ahead of what had developed into a something-less-than-static-civilization. This, as we have seen, gave rise to the Mutant-makers. But on a constructive level, it fostered the growth of a new science of psychology, vastly superior to the old Urth science, and, some suspect, considerably more refined than our own mental sciences. A particular manifestation of this lost science was the ability to project tri-dimensional images of dreams, to record them while the conscious mind slumbered, to play them back later and to interpret them unerringly....
