They do not understand the relation between the theoretical and the practical aspects of their undertaking. These failures of understanding may account for the failure so far of any psychoanalyst to make a clear, systematic statement of psychoanalysis in terms of its basic concepts, its principles, its evidences, its facts. The only cure that I know of for the influence of the 19th century is education in the European tradition which was almost completely obscured in that century. But education is not enough. To suppose that it is to make the error of assuming that men, psychoanalysts among them, are completely rational and are capable of being moved by the truth.
Prejudices are like passions.
May I borrow the technique of the psychoanalyst for a moment, and analyze his prejudices in the hope that he may get the insight that will work as a cure. I am trying to be completely submissive to objective truth and order. I am masochistic toward reason. If I were to psychoanalyze psychoanalysts, I would say that as a group they have the prejudices and passions of the narcissist. To be original in this way, they must ignore their sources in the European tradition, and they must be sadistic toward order and reason.
