Come on now." I smiled condescendingly, knowing it would irritate him. "What are you doing that's worth anything?" He glared at me, his white hair bristling and his nostrils dilated like a war horse about to whinny. I can say one thing for them—these scientists and professors always keep themselves well under control. recognize its value." Prof. Caswell smiled back tightly. He knew his department was at stake. The other departments were popular with donors and pulled in gift money by scholarships and fellowships, and supported their professors and graduate students by research contracts with the government and industry. Caswell had to show a way to make his own department resonant like most professors, when he had to explain something he to deliver an essay—"have certain tendencies built into the way they happen to have been organized, which cause them to expand or contract without reference to the needs they were founded to serve." He was becoming flushed with the pleasure of explaining his subject. "All through the ages, it has been a matter of wonder and dismay to men that a simple organization—such as a church to worship in, or a delegation of weapons to a warrior class merely for defense against an outside enemy—will either grow insensately and extend its control until it is a tyranny over their whole lives, or, like other organizations set up to serve a vital need, will tend to repeatedly dwindle and vanish, and have to be painfully rebuilt. "The reason can be traced to little quirks in the way they were organized, a matter of positive and negative power feedbacks. Such used as a base that would enable me to develop a specifically social mathematics, expressing the human factors of intermeshing authority and motives in simple formulas. amount of growth and period of life of any organization. The UN, to choose an unfortunate example, is a shrinker type organization. Its monetary support is not in the hands of those who personally benefit by its governmental activities, but, instead, in the hands of those who would personally lose by any extension and encroachment of its "Could we discuss this over lunch?" he asked. "I wouldn't mind hearing more, but I'm having lunch with some executors of a millionaire's will. They have to be convinced that by, 'furtherance of research into human ills,' he meant that the money "I see you have your problems, too," Caswell said, conceding me nothing. He extended his hand with a chilly smile. "Well, good afternoon, Mr. Halloway. I'm glad we had this talk." I shook hands and left him standing there, sure of his place in the progress of science and the respect of his colleagues, yet seething inside because I, the president and dean, had boorishly demanded that For a crumb of favorable publicity and respect in the newspapers and an annual ceremony in a silly costume, I spend the rest of the year going hat in hand, asking politely for money at everyone's door, Caswell had to make it work or get out. He was deep in the symbology of human motives and the equations of reason why the members would lose if any of them resigned, and some indirect way they could use to force each other to stay in." out a few that would have made the organization too complicated, and finally worked out an idyllically simple and deadly little organization setup where joining had all the temptation of buying a sweepstakes "This demonstration has got to be convincing. We'd better pick a little group that no one in his right mind would expect to grow." with him the President of the University, leaning across the table toward each other, sipping coffee and talking in conspiratorial tones over something they were writing in a notebook. That was us. minutes I began to feel sleepy. There were only about thirty people there, and it was a small room, not the halls of Congress, but they discussed their business of collecting and repairing second hand clothing for charity with the same endless I pointed out to Caswell the member I thought would be the natural half doze while Caswell stayed awake beside me and wrote in his "I think there's a way they could find for it," Caswell whispered back, she can be trusted with initiating the change. Just mention all the personal advantages an unscrupulous person could have." He nodded, keeping a straight and sober face as if we were exchanging admiring remarks about the techniques of clothes repairing, instead of conspiring. After the meeting, Caswell drew the tall woman in the green suit bylaws with her and went off soberly, as befitted two social science experimenters. We didn't start laughing until our car passed the town "Caswell, about that sewing club business—I'm beginning to feel the members.... Poor Caswell. The bet between us was ironclad. He wouldn't let me through the first slow move to fire him. His professional pride would be shattered, sunk without a trace. I remembered what he said about that would make for the university. And what if Caswell asked me what I had found out in the meantime? I The group with Mrs. Searles was probably holding a shrunken and almost memberless meeting somewhere in an upper room. without uncared-for ill—potentially with no ugliness, no vistas which are not beautiful—the best people in the best planned town in the " All we need is more members. Now get out there and recruit! " seated in a row of chairs, was a group that was probably the board of directors. It was mostly women, and the women began to look vaguely familiar, as if they could be members of the sewing circle. She was cheering with the crowd, her eyes sparkling. "I don't know," steeply as it reached the fourth month. They had picked up their first increase in membership simply by amalgamating with all the other types being brought in. By the fifth month, the League had added a mutual baby-sitting service that had been built into the organization plan for the distribution of the small profits of membership fees and honorary promotions. It was becoming an openly profitable business. Membership was rising more rapidly now. local real estate promoters had finished joining en masse. The Mutual Trade part sounded to me as if the Chamber of Commerce was on the point of being pulled in with them, ideas, ambitions and all. inert, cantankerous, or both. Caswell's formula could be a handle to grasp them with. Gratitude alone would bring money into the university in carload lots. were spectacular. Caswell's formulas were proven to the hilt. "Perfect, Wilt, perfect Watashaw business at all, I'm afraid. You say the demonstration went well and you're satisfied?" He was definitely putting on a chill. We were friends now, but obviously he was still peeved whenever he was reminded that I had doubted that his theory could work. And he was using its success to string of degrees after his name is just as human as anyone else. I had needled him pretty hard that first time. "I'm satisfied," I acknowledged. "I was wrong. The formulas work beautifully. Come over and see my file of documents on it if you want a He sounded cheerful again. "I didn't complicate that organization with negatives. I wanted it to grow . It falls apart naturally when it stops growing for more than two months. It's like the great stock boom before an economic crash. Everyone in it is prosperous as long as I had seen. They probably would. "No," he continued. "We'll just let it play out to the end of its tether and die of old age." The graph on the desk before me began to look sinister. Surely Caswell must have made some provision for— "You underestimate their ingenuity," I said into the phone. "Since they page. Allowing for a lag of contagion from one nation to another, depending on how much their citizens intermingled, I'd give the rest of the world in his own mind. Then he laughed weakly. "Well, you asked me for a demonstration." That was as good an answer as any. We got together and had lunch in a bar, if you can call it lunch. The movement we started will expand by hook or by crook, by seduction or by bribery or by propaganda or by
