[Psychopathologic language. 1. The double-meaning dialogue]

The psychopathological language is analysed in three forms about the intra-personnal and the inter-personnal relations: 1) The double without dialogue; 2) The ego in the soliloque; 3) The sex of the words. In this first part a clinical case is proposed by "The double" than by F. Dostoïevski. The most obscure part of the personality, the non-self, is the origine of a delusion. The development of delusion is favorised by a non-control of the dialogical structure of the language under social pressures.
