in paranoia another source of symptom formation; the delusions (symptom of return) reaching consciousness through the compromise demand a great deal of the thinking work of the ego until they can be unconditionally accepted. As they themselves are not to be influenced the ego must adapt itself to them, and hence the combining delusional formation, the delusion of interpretation which results in the transformation of the ego, corresponds here to the symptoms of secondary defense of compulsion neurosis. In this respect my case was imperfect as it did not at that time show any attempt at interpretation, this only appeared later. I do not doubt, however, that if psychoanalysis were also applied to that stage of paranoia, another important result would be established. It would probably be found that even the so called weakness of memory in paranoiacs is purposeful, that is, it depends on the repression and serves its purpose. Subsequently even those non-pathogenic memories which stand in opposition to the transformation of the ego become repressed and replaced; this the symptoms of return imperatively demand.
