The theoretical approach of H. von Foerster (1974), linking communication, language and personal identity in a common non linear, dynamic formalism, helps to articulate pathological phenomena observed in clinic and cognitive models. interpretation of the objects and events he perceives. This results in a genetic interdependence of cognitive systems (language, identity, communication, etc.). In formal terms, to generate these systems, the von Foerster approach uses recursive dynamic models which (by their very definition) take into account the genetic development of systems to define their attractors. Personal identity could be represented as a dynamic system with one (or more) attractors (linked to various constraints). We intend to show how such dynamic models can be used to characterize certain properties of normal or pathological personal identity. We will not speak about all personal identities disorders encountered in clinical studies, - the problem of identity is at the heart of the concept of schizophrenia, in an almost etymological sense (concepts of dissociation, discordance, etc.) ; - the multi-dimensional aspects of this disorder (biological, social, cognitive...) exclude no methodologies a priori ; - in the history of psychiatry, schizophrenia has always constituted a privileged domain to conceptualize psychosis.
