"Talcott Parsons, the "incurable theorist" in his own words,... brought together, in a systematic and generalized form, the main outlines of a conceptual scheme of social action and systems (e.g. 1951). His frame of reference focused on the description of the system of institutionalized roles, motivational process, economic exchange, political power and other Issues that according to his view should be included in a general sociological theory."
