[The complexity problem and reductionist solutions--critical comments from the psychoanalytic viewpoint]

We refer to the essentials of the complexity of psychosomatic and psychoneurotic phenomena and how to comprehend this complexity. Measurement is called in question as a possibility to describe psychic phenomena. We make a suggestion to preserve the advantages and to overcome the disadvantages (selective awareness, no generalization, no intersubjective validitation) of clinical psychoanalytic research work.
