Abstract
The paper discusses examples of integrative metatheoretical and theoretical work undertaken in the spirit of unification. Unification is defined as a recursive process in which the outcome of any one integrative episode provides ideas that may enter into further such episodes. The conceptual materials entering into integration exist at different levels and in distinct contexts. At the metatheoretical level, the examples relate to a number of contexts and issues, including methodological individualism versus holism. At the theoretical level, two examples of the idea of a unification episode are described. In each instance, the ideas entering into the integrative episode are drawn from distinct research programs. It is argued that the spirit of unification, as embodied in theoretical practice along the lines suggested by the examples, can create bridges between disparate theory enterprises so as to help break down particularistic barriers within sociological theory
