and imagination--which is merely
the re-arrangement of reality or of thoughts derived from reality.

We are perhaps in much that same position. To be sure, our telescopes
bring us data from stars that are so far away the human race will never
reach them--but is not our telescope a "screen" that brings us only the
one-inch rocks?

There may be and probably is a vast realm of reality co-existent with
the reality we know, right around us; but it is "screened" from us. It
may be possible that we know less than ten percent of actual reality
around us due to the screening of our senses and our instruments that
blocks completely, or permits to pass completely, every energy pattern
that can't pass through the "holes" of our "screen."

Going back to Kah, the one-inch-rock-universe observer, suppose that in
one batch of dirt dumped at the head of the screening system there
happened to be no one-inch rocks at all? Or, more closely to the story
you are about to read, suppose, with his mind deeply grooved with the
tracks of the one-inch rocks, he were to move to a vantage point where
there were no one-inch rocks, but larger or smaller ones?

He would immediately find nature behaving according to an utterly
strange pattern, BUT he could only sort the incoming sensations
according to the neural grooves already built up in his mind! In his
mind he could only see one-inch rocks or nothing, and since what he
would see would obviously be something, it would either seem nothing to
him, or one-inch rocks behaving strangely.

His instruments and his mind would interpret by the old gradations and
scales and concepts. His Universe would still be made of nothing but
one-inch rocks, to him, but its behavior would be strange.

Perhaps slowly, like a newborn child making sense out of its
surroundings, or a foreigner slowly making sense out of our language, he
would penetrate to the new reality with his mind. Perhaps in the very
process his being would change its structure.

In the end he would be in a unique position. He would have the memories
of one Reality, and the experiences of a new one. He would have the
language of the old with which to describe the new to his old
companions. Could he do it so they would comprehend it?

It would do him no good simply to invent new words to describe something
beyond the experience of his old companions. He would have to describe
something beyond their experience with words and sentences they had
cr
