The application of psychoanalysis to sociology must definitely guard against the mistake of wanting to give psychoanalytic answers where economic, technical, or political facts provide the real and sufficient explanation of sociological questions. On the other hand, the psychoanalyst must emphasize that the subject of sociology, society, in reality consists of individuals, and that it is these human beings, rather than abstract society as such, whose actions, thoughts, and feelings are the object of sociological research.
