"I take it you're not a mathematician yourself."
"Anything but," said Dors with a short laugh. "Anything. History is my field. I've already published some studies on the rise of Trantor-I mean the primitive kingdom, not this world. I suppose that will end up as my field of specialization-Royal Trantor."
"Wonderful," said Seldon.
"Wonderful?" Dors looked at him quizzically. "Are you interested in Royal Trantor too?"
"In a way, yes. That and other things like that. I've never really studied history and I should have."
"Should you? If you had studied history, you'd scarcely have had time to study mathematics and mathematicians are very much needed-especially at this University. We're full to here with historians," she said, raising her hand to her eyebrows, "and economists and political scientists, but we're short on science and mathematics. Chetter Hummin pointed that out to me once. He called it the decline of science and seemed to think it was a general phenomenon."
Seldon said, "Of course, when I say I should have studied history, I don't mean that I should have made it a life work. I meant I should have studied enough to help me in my mathematics. My field of specialization is the mathematical analysis of social structure."
"Sounds horrible."
"In a way, it is. It's very complicated and without my knowing a great deal more about how societies evolved it's hopeless. My picture is too static, you see."
"I can't see because I know nothing about it. Chetter told me you were developing something called psychohistory and that it was important. Have I got it right? Psychohistory?"
"That's right. I should have called it 'psychosociology,' but it seemed to me that was too ugly a word. Or perhaps I knew instinctively that a knowledge of history was necessary and then didn't pay sufficient attention to my thoughts."
"Psychohistory does sound better, but I don't know what it is."
"I scarcely do myself." He brooded a few minutes, looking at the woman on the other side of the table and feeling that she might make this exile of his seem a little less like an exile. He thought of the other woman he had known a few years ago, but blocked it off with a determined effort. If he ever found another companion, it would have to be one who understood scholarship and what it demanded of a person.
To get his mind onto a new track, he said, "Chetter Hummin told me that the University is in no way troubled by the government."
"He's right."
Seldon shook his head. "That seems rather unbelievably forbearing of the Imperial government. The educational institutions on Helicon are by no means so independent of governmental pressures."
"Nor on Cinna. Nor on any Outworld, except perhaps for one or two of the largest. Trantor is another matter."
"Yes, but why?"
"Because it's the center of the Empire. The universities here have enormous prestige. Professionals are turned out by any university anywhere, but the administrators of the Empire-the high officials, the countless millions of people who represent the tentacles of Empire reaching into every corner of the Galaxy-are educated right here on Trantor."
"I've never seen the statistics-" began Seldon.
"Take my word for it. It is important that the officials of the Empire have some common ground, some special feeling for the Empire. And they can't all be native Trantorians or else the Outworlds would grow restless. For that reason, Trantor must attract millions of Outworlders for education here. It doesn't matter where they come from or what their home accent or culture may be, as long as they pick up the Trantorian patina and identify themselves with a Trantorian educational background. That's what holds the Empire together. The Outworlds are also less restive when a noticeable portion of the administrators who represent the Imperial government are their own people by birth and upbringing."
Seldon felt embarrassed again. This was something he had never given any thought to. He wondered if anyone could be a truly great mathematician if mathematics was all he knew. He said, "Is this common knowledge?"
"I suppose it isn't," said Dors after some thought. "There's so much knowledge to be had that specialists cling to their specialties as a shield against having to know anything about anything else. They avoid being drowned."
"Yet you know it."
"But that's my specialty. I'm a historian who deals with the rise of Royal Trantor and this administrative technique was one of the ways in which Trantor spread its influence and managed the transition from Royal Trantor to Imperial Trantor."
Seldon said, almost as though muttering to himself, "How harmful overspecialization is. It cuts knowledge at a million points and leaves it bleeding."
Dors shrugged. "What can one do?-But you see, if Trantor is going to attract Outworlders to Trantorian universities, it has to give them something in return for uprooting themselves and going to a strange world with an incredibly artificial structure and unusual ways. I've been here two years and I'm still not used to it. I may never get used to it. But then, of course, I don't intend to be an administrator, so I'm not forcing myself to be a Trantorian.
"And what Trantor offers in exchange is not only the promise of a position with high status, considerable power, and money, of course, but also freedom. While students are having their-education, they are free to denounce the government, demonstrate against it peacefully, work out their own theories and points of view. They enjoy that and many come here so that they can experience the sensation of liberty."
"I imagine," said Seldon, "that it helps relieve pressure as well. They work off all their resentments, enjoy all the smug self-satisfaction a young revolutionary would have, and by the time they take their place in the Imperial hierarchy, they are ready to settle down into conformity and obedience."
