Mechanisms, organisms and social systems
指出传统上用于理解社会系统的机械和有机体模型存在缺陷，并提出了第三种模型，旨在从社会系统自身特性出发进行理解。
Abstract To think about anything requires an image or concept of it, a model. To think about a thing as complex as a social system most people use a model of something similar, simpler and more familiar. Traditionally, two types of models have been used in efforts to acquire information, knowledge and understanding of social systems: mechanistic and organismic. But, in a world of accelerating change, increasing uncertainty and growing complexity, it is becoming apparent that these are inadequate as guides to decision and action. The growing number of social crises and dilemmas that we face should be clear evidence that something is fundamentally wrong with the way we think about social systems. In this paper we describe and try to explain the deficiencies of the two traditional ways of thinking about social systems. We then develop a third type of model, one we believe does not suffer from these inadequacies, a social system model which seeks to penetrate beyond the nature of machine and organisms to understand social systems in their own right.
