Obsessive-compulsive phenomenon in a so-called 'symptomarme schizophrenie': from the viewpoint of structural dynamics in defense mechanisms.

(1)'Antieidos' is a formlessness that results from the reverse intentionality of the life formation and is considered to be a principle of obsessive psychosis. 'Internal emptiness' is supposed to exist in the nucleus of schizophrenia. 'Antieidos' and 'internal emptiness' are in close proximity, partly overlapping each other. Obsessive psychosis and some types of simple schizophrenia are considered to have a common intentionality for the obsessive-compulsive phenomenon from the viewpoint of defensive structural dynamics. (2) The obsessive-compulsive phenomenon and the hypochondriacal phenomenon that coexist in simple schizophrenia are considered to be a 'noema' (something in which a meaning is given to the intended experience) that results from 'noesis' (action of consciousness seen in the intended experience) which has a defensive intentionality and as a result masks the basic disturbance in schizophrenia. Complementarity between the obsessive-compulsive phenomenon and the hypochondriacal phenomenon structured in this way can form one type of disease in the nonself-introspective category of simple schizophrenia.
