(There was a stupid little running machine that she had discovered once that was perpetually scurrying about looking for things to do. It would never have survived on Earth because there was an unexpected flaw in it. She herself had sensed the fault and started to fix it only to realize that here was an unexpected stroke of luck. Curiosity circuits there were by the million but they were all mechanical and what they produced could be strictly predicted. But this was unique. A deviation in the manufacturing process, a slight change in the density of the material, whatever it was something extraordinarily fine had been put together and it would take a hundred years of chance to duplicate it.) (Midway she had changed her mind and instead had altered the machine to encourage the basic sensitivity. She hadn't seen it recently. She hoped someone who didn't understand hadn't undone her work.) The known order crumbled under the touch into something that was strange. But where sight itself would not suffice, it was possible to touch reality, to soak it into the skin, like understanding which cometh slowly to the growing mind. But what was understanding? Parts of it were always left out and she could venture toward it only a little way. She twisted the head on the bench. The silence was unchanging. (What was silence?) Other heads on the bench didn't move; they weren't supposed to. Once they had been attached to clumsy machines and could move about with a stiff degree of freedom. They couldn't now, though they could twist the light perceptors in whichever direction suited them. But they didn't know where to look. She herself couldn't see the thing that was approaching. It was because her eyes were imperfect. Lenses were pliable and nerve endings were huge things, too gross to catch the instant infinitesimal signals. Or perhaps it was permeability--force bounced on distant impenetrability and bounded back to and through her senses. She'd have to align the heads to help them help her, string them together for what reinforcement they offered each other. And still they wouldn't see because what they depended on for seeing was too slow. By itself the hookup wouldn't correct their sight. But nearby was a fast mind though a lazy one. It liked routine once the meaning of it was made clear. And it worked with instantaneity. Blind itself it could fingertip touch the incredible impulses and interpret what it felt for those who had eyes. It would join with her, reluctantly but surely if she made it interesting, a game at which it could always win. And winning wouldn't be difficult for it, not against these nine circuit bound minds, even if it was true that they did augment one another. Singly there were stupid and even added they were not much better. Their virtue was that they were electronic.
