There is an original convergence between the results of psychiatric research on schizophasia, cognitive psychology studies on the neural integration of linguistic data, and the poetic assertions of Boileau in the seventeenth century. Research on schizophasia has enabled the establishment of explanatory models of language disorders in schizophrenia, implicating a central function of synthesizing linguistic data into units of meaning. Yet people with schizophrenia would use the same process as non-schizophrenic patients to achieve this synthesis. The neuropsychologist Stanislas Dehaene provides a descriptive model of this process involving three parallel neuronal structures responsible for managing phonetic, syntagmatic, and semantic information. He demonstrates that this process relies on the rhythmic structure of utterances. Several centuries earlier, Boileau, in Art Poétique, already encouraged poets to use the rhythm of their verses to facilitate the assimilation of meaning.This convergence can be explained by the sharing of the same linguistic conceptual foundations between the different approaches. The common linguistic presupposition could be described as the parallelism of words and meaning. Thus, while neuropsychology and cognitivist models of schizophasia openly claim their affiliation to the linguistic models of Noam Chomsky, the case of Boileau urges us to trace the linguistic conceptual foundations of psychiatry much further back.When it comes to theses linguistic presuppositions, can the paradigm shift that occurred in poetry with Romanticism be matched in psychiatry?
