Homo Novis

".....We define thinking as integrating data and arriving at correct answers. Look around you. Most people do that stunt just well enough to get to the corner store and back without breaking a leg. If the average man thinks at all, he does silly things like generalizing from a single datum. He uses one-valued logics. If he is exceptionally bright, he may use two-valued 'either-or' logic to arrive at his wrong answers. If he is hungry, hurt, or personally interested in the answer, he can't use any sort of logic and will discard observed fact as blithely as he will stake his life on a piece of wishful thinking. He uses the technical miracles created by superior men without wonder nor surprise, as a kitten accepts a bowl of milk. Far from aspiring to higher reasoning, he is not even aware that higher reasoning exists. He classes his own mental process as being of the same sort as the genius of an Einstein. Man is not a rational animal; he is a rationalizing animal.

"That is why there is always room at the top, why a man with a leetle more on the ball can so easily become governor, millionaire, or college president--and why homo sap is sure to be displaced by New Man, because there is so much room for improvement and evolution never stops.

"Here and there among ordinary men is a rare individual who really thinks, can and does use logic in a single field--he's often as stupid as the rest outside his study or his laboratory--but he can think, if he is not disturbed, sick, or frightened. This rare individual is responsible for all the progress made by the race; the others reluctantly adopt his results. Much as the ordinary man dislikes and distrusts and persecutes the process of thinking he is forced to accept the results occasionally, because thinking is efficient compared with his own maunderings. He may still plant his corn by the dark of the moon, but he will plant better corn developed by better men than he.

"Still rarer is the man who thinks habitually, who applies reason, rather than habit pattern, to all his activity. Unless he masks himself, his is a dangerous life; he is regarded as queer, untrustworthy, subversive of public morals; a pink monkey among the brown monkeys--a fatal mistake. Unless the pink monkey can dye himself brown before he gets caught.

"The brown monkey's instinct to kill is correct; such men are dangerous to all monkey customs.

"Rarest of all is the man who can and does reason at all times, quickly, accurately, inclusively, despite hope or fear or bodily distress, without egocentric bias or thalmic disturbance, with correct memory, with clear distinction between fact, assumption and non-fact. Such men exist, They are "New Man"--human in all respects, indistinguishable in all appearances or under the scalpel from homo sap, yet as unlike him in action as the Sun is unlike a single candle.”
