Freud's theory of paranoid delusion based on the Schreber case contrasted with related theories

Abstract

The historic importance of Freud's analysis of the Schreber case is acknowledged, even though the theory it expounds is largely disavowed. The theory ascribes the cause of paranoid delusion to homosexual impulses unresolved in infancy or early childhood. This paper summarizes Freud's monograph on Schreber and contrasts his theory with the views of various revisionists. The writers focus on the Freudian concept of projection, which is intended to explain how much meaning can become reversed under the impetus of stress, and the reversal lead to delusional thinking. Based on their work in family therapy, where they observed one form of pathogenic relating termed learning to be possessed, the writers concluded that this form was also based on a type of projection which could culminate in delusional ideation. A relationship between learning to be possessed and H. S. Sullivan's theory of paranoid transformation is described. A learning factor is present in several of the psychological theories advanced to explain delusion, and the factor is akin to if not identical with Freud's concept of projection.
