Development of the field of social change has seriously lagged during the past generation. Retardation has been due to numerous forces, among them a structural and functional bias which in emphasizing the study of organizational adjustment to innovation has restricted the scope of change theory and research. Additionally, an emphasis upon cultural, as distinct from social, processes has obscured the interactional roots of change. Also the repudiation of 19th century evolutionary thought has tended to make suspect any directional, long range theorizing. A revitalization of social change analysis in the fullest develomental sense is required for the comprehension of change sequences and processes in the new nations. It is probable that our most feasible methodology for a “sociology of development” lies in the construction of a series ofrealmodels as refinements of the Gemeinschaft-Gesellschaft, Sacred-Secular theoretical tradition.
