Arieti, Lógica Aristotélica, Paleológica, Esquizophrenia


The Aristotelic Logic, which is characterized by four laws, is commonly accepted as being representative of normal though, when considered in its formal aspect. Arieti defends the existence of another logic, one that he has designated "Paleological", which was dominant in human beings in the beginning of their evolution, and that also occurs in certain characteristics of infantile thought, as well as in the primary process (manner in which the unconscious operates). The same author considers that this logic, whoch is quiescent, emerges in schizophrenic thought, dominating and overlapping the Aristotelian logic. In order to escape from anguish, the shizophrenic patient abandons Aristotelian norms of thought and adopts the Paleological form, because by interpreting reality, in light of Aristotelian logic, it's felt to be threatening and unbearable. Finally, Arieti explains that the principles of Paleological thought don't explain the phenomenon dynamically, merely formally. The study of psychodinamic mechanisms reveals what and why (content and motivation), while the study of formal mechanims reveal how, thoughts and feelings are processed.
