Abstract
Applied sociology will be understood in the following discussion as a unique and original form of sociology; i.e., in its logic and practice distinguished from traditional sociology it is understood as an explanatory body of knowledge and an intellectual discourse about intentional/purposeful social action and behavior. The application of sociology proper to such substantive fields as family, art, law and sport, commonly called applied sociology, which reproduce the body of sociological knowledge just a second time, is not part of such understanding. Applied sociology in its original sense has its own logic in which purpose, implementation and the process of social-problem solution are crucial. It will in the end lead to an applied action or implementation theory. It is, to paraphrase Lazarsfeld, the methodology of “sociology in action” (1960).
