Caliban - By Isaac Asimov,Roger E. Allen Page 0,12

fresh and vibrant wonder. He saw the bright pinpoints of light in the sky and wondered what they were. He noticed a few bits of litter blown against a fence and wondered how such a strange combination of objects had come to be there. His datastore was mute on both of those subjects, and many others besides, but on the whole it was a splendid guide, telling him any number of things about the city through which he walked. He wandered everywhere, eagerly looking about at everything, marveling at all things. And if stars and litter were not explained, many other things were. More often than not, he could look at a thing, and wonder about it, and find that the datastore could identify it and explain it for him.

He was content for some time to wander the city, passively absorbing whatever the datastore saw fit to tell him about what he saw. Then Caliban had an idea. If the map and the datastore could work to tell him about what was before him, could they not also guide his steps? Perhaps he could examine the datastore ' s map, select an interesting destination, and travel to it.

He stopped in his tracks and tried the experiment. The outside world seemed to fade from his sight. Suddenly he was looking down on a map-schematic of the area he was in, done in bold primary colors and carefully designed symbols.

He tried to push outward from that point and was greatly pleased to discover that the simple act of wishing it to be so allowed him to visualize the entire city map, or focus in on any portion of it. Nor, he found, did his virtual viewpoint have to stayabove the map. He could move down to ground level and see the buildings and hill tower over him. He could visualize the map data from any angle or position.

A few moments of experimentation confirmed it: He could manipulate his viewpoint to any spot in or over the map, look at the lay of the land from a bird's-eye view, or from ground level at any position, with the buildings and streets presented in the proper shapes and sizes. His vision swept along great swatches of the city, across the parks, the buildings, the great roads. It was as if he were traveling through those places in his mind. The sensation was exhilarating, almost one of flight.

There were datatags on the map, offering information on the buildings-their names and addresses, and in many cases the names of whatever businesses went on there.

Suddenly he got a splendid idea. He could use the datatag information to learn more about himself. He manipulated his viewpoint within the map and brought it back to his present position. Then he proceeded to retrace his steps back to the building he had started out from. He could read the datatags connected to the building and learn what sort of place it was, see what other information the map held concerning it. Certainly he could find clues to his own identity, his place in the world. Eager to find out more about himself, he moved his viewpoint rapidly across the map, back the way he had come.

The map imagery rushed past him at a breakneck pace, twisting and turning violently, reversing his movements at tremendous speed. At last the images came back to his starting place. He made a strange discovery: The image of the building was incomplete. Nearly every other building was shown in great detail, with doors and windows and basic elements of the architecture clearly shown. But the map showed this building as nothing but a featureless grey rectangular solid, a low, long shape on the land.

Confused, Caliban accessed the datatag system.

And discovered that the map had no information whatsoever about the building inside which he had awakened.

Stunned, surprised, Caliban shut down the map display system. The bright colors and symbols of the map faded from his vision, and he found himself once again standing in the darkness, alone on an empty pathway in a quiet residential district.

Whywas there no information about that building? Perhaps he should go back there, examine the place firsthand. He of course had a perfect, detailed memory of what he had seen there, and no doubt he could work his way back through those memories for information. But he had not been looking for anything when he awakened, had not even been fully aware that he should have known more than he did.
