RESUMO
With Bateson we want to look for the structure that connects form, process and typology. We do not believe that distinctions are representation of dualism: according to the model proposed by the Second Cybernetics, the distinctions are considered as different sides, that is, an overlap of levels in which one term derives from the other. The logic of the relationship between form and process implies different levels in a self-reference model in which one part is pulled out of the other. At present, speaking about typology, makes sense in order to correlate some complex factors. The first one implies the multidimensionality of intrapsychic and relational reality. The second, a continuous process of self-consciousness of different analytic levels of "reality". The third considers a diagnosis (and typology) as a part of the "information" for the therapist, his patient, his family and his interpersonal context.
