question:  Why is Caswell so confident that his organizational model will cause the group to grow?
context: Wilton Caswell, Ph.D., was head of my Sociology Department, and right then he was mad enough to chew nails. He bit off each word with great restraint: "Sociology is the study of social institutions, Mr. Halloway." He had a book in his hand and I was expecting him to throw it, but he spoke instead: "This department's analysis of institutional accretion, by the use of open system mathematics, has been recognized as an outstanding and valuable contribution to—" The words were impressive, whatever they meant, but this still didn't sound like anything that would pull in money. If they got the idea that sociology professors are giving advice and guidance—No, we have to stick to brass tacks and leave Washington out of this. "Institutions—organizations, that is—" his voice became more resonant; like most professors, when he had to explain something he instinctively slipped into his platform lecture mannerisms, and began 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." Such simple questions as, 'Is there a way a holder of authority in this organization can use the power available to him to increase his power?' provide the key. In working on the problem, I found that the mathematics of open system, as introduced to biology by Ludwig von Bertalanffy and George Kreezer, could be 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. "By these formulations, it is possible to determine automatically the amount of growth and period of life of any organization. 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 he produce something tangible.
