'I'll tell you the best thing that I ever was. It wasn't any man, no old human ancestor, or even close to human. I'm not sure some of the old man-things I was were human. This best thing was a sort of lizard. I don't know what it was, nor does anyone else. Ecuyer had a hell's own time trying to figure out what it was. He even sent for some books that he thought might tell him what it was, but they didn't. What it was never bothered me, but it did him. I guess it must have been some sort of missing link, a critter that never left a skeleton for paleontologists to dig up and ponder over. I figure, and so does Ecuyer, that it lived back in the Triassic. I said a lizard, but it probably wasn't any lizard. It wasn't big, but it was fast — it was one of the fastest things that lived at that time. And mean. Christ, was it mean! It hated everything, it fought with everything, it would eat anything that moved. It harried the hell out of everything in sight. I never knew until then how good it made a man feel to be really mean. Bone-chilling mean. A real, low-down bastard. The time I spent as a trilobite was short, but I lived as this lizard for a longtime. I don't know how long, for there was no sense of time. I just lived in the middle of forever. Maybe I stayed with it so long because I was enjoying myself so much. Why don't you ask Ecuyer to dig out that lizard cube for you? You'd enjoy it.
'Perhaps someday I will, said Tennyson.
He did not view the lizard cube. There were too many others. Ecuyer had no objection to his seeing them. He gave the robot custodian of the Listening files instructions to show Tennyson any that he wished, suggested a long list that he should see.
It was puzzling, Tennyson told himself. Here he was, a stranger, and still the files were being opened to him. As if, in all fact, he was a member of the project. And in the Vatican library, the historical record had been made available to Jill. None of it squared with what the cardinal had told Jill when she had her interview with him — that Vatican was adamant in its refusal to allow any public exposure. The answer must be, he told himself, that Vatican was confident it could guard against public exposure by refusing to allow anyone with knowledge of its operations to leave the planet.
Or it might be that by revealing its operations to Jill and him, both of them would be won over to the case. Vatican was made up of a band of dedicated fanatics isolated from the nearby galaxy — the only part of the galaxy that counted, the only part of it that was close enough to be tempted to move in — and out of this dedication and isolation the fact of Vatican and its purpose would loom larger in their eyes than it really was. Thus Vatican would fall victim to its egocentrism, and the cause would seem so grand, so sacred and so clearly reasonable that no one, adequately informed, could do anything but align himself with it. All that needed to be done was to explain and everyone would fall in line.
Tennyson shook his head over the puzzle. The line taken by Vatican was illogical. They could, if they had wished, have sent both him and Jill packing when Wayfarer lifted off to return to Gutshot. Certainly both of them would have known something of Vatican, but very little of what was actually going on. Jill could write her article detailing how she had been thrown off the planet. But in the midst of all the causes, all the crusades, all the quarrels, all the problems of the galaxy — such an article would have made no more impression than the slightest ripple occasioned by a thrown stone in a storm-tossed ocean.
The simplest answer, and the one that he was most reluctant to accept, was that both of them were needed here. Certainly there was need of a doctor to care for the human population; it might be true that Vatican felt a real need for the writing of its history. And it was true, as well, that it was difficult for such an out-of-the-way place to attract outside professionals, so difficult that when a couple of them dropped unannounced onto the planet, Vatican would latch onto them. But, for some reason that he was not able to understand, Tennyson was reluctant to accept such a thesis. He could not, for one thing, accept the thought that Jill and he could be so important to them. Unless, and this he kept coming back to, Vatican had no intention of allowing them to leave.
One of the cubes he viewed was highly disturbing. Even inside the mind of one of its inhabitants, which he assumed was where he was, it was a sort of place that made no human sense, was entirely incomprehensible. What he saw, although he realized later that it was not really seeing, was a world of diagrams and equations, or what he took to be diagrams and equations, although he saw no conventional signs or symbols even vaguely comparable to human ones. It was as if he existed somewhere inside a huge three-dimensional blackboard, with the signs and symbols, the diagrams and equations grouped about him and, on all sides, receding far into the distance. And it seemed at times, although how he sensed this he did not know, that he himself, or the entity whose mind he shared, was itself an equation.
He sought vainly for an answer, for an explanation, feebly probing the mind of his host, but getting no reaction. The creature, he thought, more than likely, didn't know he was there. It itself needed no answer or explanation; it understood what it was seeing. Perhaps interpreting what it was seeing, sharing in the experience of its interactions with all the other diagrams and equations. But if so, all this escaped Tennyson. He was lost in a sea of unknowing.
He did not give up; he stayed in there and fought for some sort of understanding, trying to seize just one thing, one small bit of relevance that he could tuck away as a start toward an understanding.
That one bit of relevance never came. When the cube came to an end and he found himself back in the human world, he knew as little as he did when popped into that other mind.
He sat, stricken, in the chair.
'That was quite something, was it not, sir? asked the custodian, chirping blithely.
Tennyson rubbed his hand across the face, trying to clear away the fog.
'Yes, he said. 'What was it?
'Sir, we do not know.
'What good, then, he asked, 'of finding it, of seeing it?
'Vatican may know, said the custodian. 'Vatican has ways of knowing.
'Well, I sincerely hope so, said Tennyson, rising from the chair. 'That's all I can stand today. How about tomorrow?
'Certainly, sir. Tomorrow. Any time you wish.
