Plassmann introduces the expressions organ fantasies, pathological zones in the body self, and organ world, with the intention of formulating an analytic psychology of the body. He believes that a person's own body has the significance of a primary object which, under normal circumstances, enables the person to have several important basic experiences, such as that of being alive and of being separate from others. On the basis of his work with borderline patients, the author demonstrates that the pathological zones in the body self can be understood by means of a phase model, and that the illness-producing effect of a pathological organ world is related to a defective symbolization of experiences. The author proposes that the analytic psychology of the body can be applied to psychosomatic illness as well.
