This paper considers the goals and methods of theoretical sociology. The chief goal of theoretical work is a theory in two parts-postulates and predictions-the key challenge being to minimize the number of postulates and maximize the number and variety of predictions. The paper discusses the distinctive character of the sentences in each part of the theory and, in light of that bipartite structure, the two main activities of theoretical analysis: (i) speculative thinking, whereby the theorist identifies the starting ideas for (...) the postulates; and (ii) formal reasoning, whereby the theorist constructs the postulates and derives predictions from them. To illustrate the features of a theory and the tasks of theoretical analysis, the paper briefly sketches the theory of the distributive-justice force. (shrink)

The goal of sociology, and all social science, is to produce reliable knowledge about human behavioral and social phenomena. To reach that goal, we undertake three kinds of activities: theoretical work, empirical work, and, even more basic, we develop frameworks that assemble the fundamental questions together with the fundamental tools that will be used to address them. This article examines the three sets of activities and their interrelations. Both deductive and nondeductive theory are highlighted, as are three kinds of empirical (...) work—testing the predictions of deductive theories, testing the propositions produced by nondeductive theories, and extratheoretical measurement and estimation. Illustrations are drawn from the fields of status, justice, and migration. (shrink)
