Émile Durkheim's early analysis of structural differentiation and modes of integration is reconciled with his later examination of interaction and ritual These ideas are reconciled by initially constructing an abstract causal model and then converting various causal paths into general laws of human social organization. It is argued that, despite a number of problems in interpreting Durkheim's analysis of cause and function, it is still possible to construct a general model that summarizes the basic classes of variables in his theory. And, despite Durkheim's failure to analyze power and inequality extensively, the contours of an important ecological theory are nonetheless evident By converting the causal model into abstract laws, this theory is seen to denote some of the most basic dynamics of the social universe.
