The resurgence of rational choice theory in sociology has given rise to a debate about its scope and limits. This paper approaches the debate in a constructive spirit. Taking Coleman's recent work as exemplary of rational choice theory in sociology, the discussion begins by noticing some elements common to this theory and to the framework employed by neofunctionalist critics of rational choice theory. First, the concept of control plays a central role in both theoretical models. Second, both theories attempt to (...) generalize the general equilibrium theory of economics, thereby capturing the economic theory as a special case. The constructive work consists of showing how key concepts of one model relate to analogous key concepts in the other. The aim is to forge the beginning of the synthesis in which the strengths of each model are preserved in one that includes both. (shrink)
