“It is our opinion,” he said, “that sapience may be defined as differing from nonsapience in that it is characterized by conscious thought, by ability to think in logical sequence and by ability to think in terms other than mere sense data. We—meaning every member of every sapient race—think consciously, and we know what we are thinking. This is not to say that all our mental activity is conscious. The science of psychology is based, to a large extent, upon our realization that only a small portion of our mental activity occurs above the level of consciousness, and for centuries we have been diagraming the mind as an iceberg, one-tenth exposed and nine-tenths submerged. The art of psychiatry consists largely in bringing into consciousness some of the content of this submerged nine-tenths, and as a practitioner I can testify to its difficulty and uncertainty.
“We are so habituated to conscious thought that when we reach some conclusion by any nonconscious process, we speak of it as a ‘hunch,’ or an ‘intuition,’ and question its validity. We are so habituated to acting upon consciously formed decisions that we must laboriously acquire, by systematic drill, those automatic responses upon which we depend for survival in combat or other emergencies. And we are by nature so unaware of this vast submerged mental area that it was not until the first century Pre-Atomic that its existence was more than vaguely suspected, and its nature is still the subject of acrimonious professional disputes.”
There had been a few of those, off and on, during the past four days, too.
“If we depict sapient mentation as an iceberg, we might depict nonsapient mentation as the sunlight reflected from its surface. This is a considerably less exact analogy; while the nonsapient mind deals, consciously, with nothing but present sense data, there is a considerable absorption and re-emission of subconscious memories. Also, there are occasional flashes of what must be conscious mental activity, in dealing with some novel situation. Dr. van Riebeek, who is especially interested in the evolutionary aspect of the question, suggests that the introduction of novelty because of drastic environmental changes may have forced nonsapient beings into more or less sustained conscious thinking and so initiated mental habits which, in time, gave rise to true sapience.
“The sapient mind not only thinks consciously by habit, but it thinks in connected sequence. It associates one thing with another. It reasons logically, and forms conclusions, and uses those conclusions as premises from which to arrive at further conclusions. It groups associations together, and generalizes. Here we pass completely beyond any comparison with nonsapience. This is not merely more consciousness, or more thinking; it is thinking of a radically different kind. The nonsapient mind deals exclusively with crude sensory material. The sapient mind translates sense impressions into ideas, and then forms ideas of ideas, in ascending orders of abstraction, almost without limit.
“This, finally, brings us to one of the recognized overt manifestations of sapience. The sapient being is a symbol user. The nonsapient being cannot symbolize, because the nonsapient mind is incapable of concepts beyond mere sense images.”
Ybarra drank some water, and twisted the dial of his reading screen with the other hand.
“The sapient being,” he continued, “can do one other thing. It is a combination of the three abilities already enumerated, but combining them creates something much greater than the mere sum of the parts. The sapient being can imagine. He can conceive of something which has no existence whatever in the sense-available world of reality, and then he can work and plan toward making it a part of reality. He can not only imagine, but he can also create.”
He paused for a moment. “This is our definition of sapience. When we encounter any being whose mentation includes these characteristics, we may know him for a sapient brother. It is the considered opinion of all of us that the beings called Fuzzies are such beings.”
Jack hugged the small sapient one on his lap, and Little Fuzzy looked up and murmured, “He-inta?”
