He smiled broadly and stood up to ease the tension in the room. "Well, it appears you have made your decision. Of course, Congress can accept the Ryke plan whether we approve or not, but it is good to go on record one way or the other. I suppose that on the way out tonight it would be proper to check in at Personnel and file a services available notification." And then he wished he hadn't said that. Their faces grew a little more set at his unappreciated attempt at humor. * * * * * Showalter remained after the others left. He sat across the desk while Hockley turned back to the window. Only the tip of the gammatron tower now caught the late afternoon sunlight. "Maybe I'm getting old," Hockley said. "Maybe they're right and the Lab isn't worth preserving if it means the difference between getting or not getting tutelage from the Rykes." "But you don't feel that's true," said Showalter. "No." "You're the one who built the Lab into what it is. It has as much worth as it ever had, and you have an obligation to keep it from being destroyed by a group of politicians who could never understand its necessity." "I didn't build it," said Hockley. "It grew because I was able to find enough people who wanted the institution to exist. But I've been away from research so long--I never was much good at it really. Did you ever know that? I've always thought of myself as a sort of impressario of scientific productions, if I might use such a term. Maybe those closer to the actual work are right. Maybe I'm just trying to hang on to the past. It could be time for a jump to a new kind of progress." "You don't believe any of that." Hockley looked steadily in the direction of the Lab buildings. "I don't believe any of it. That isn't just an accumulation of buildings over there, with a name attached to them. It's the advancing terminal of all Man's history of trying to find out about himself and the Universe. It started before Neanderthal climbed into his caves a half million years ago. From then until now there's a steady path of trial and error--of learning. There's exultation and despair, success and failure. Now they want to say it was all for nothing." "But to be pupils--to let the Rykes teach us--" "The only trouble with Silvers' argument is that our culture has never understood that teaching, in the accepted sense, is an impossibility. There can be only learning--never teaching. The teacher has to be eliminated from the actual learning process before genuine learning can ever take place. But the Rykes offer to become the Ultimate Teacher." "And if this is true," said Showalter slowly, "you couldn't teach it to those who disagree, could you? They'd have to learn it for themselves."
