Este trabajo inscripto en la investigación titulada "Trastornos de lenguaje y estructura de la psicosis", en su última fase dedicada al estudio de la función de la escritura, se propone examinar un contrapunto entre dos escritores: James Joyce y Fernando Pessoa, que surge de la puesta en tensión de dos modos de hacer con el nombre propio. En un caso el hacerse un nombre que consagra al nombre de Joyce al estudio de generaciones de universitarios, que reconocen en él, él escritor y en el otro caso el darse nombres - fenómeno de la heteronimia - en el que no se consigue la captura que amarraría a una solo nombre la obra de Pessoa. Palabras clave Nombre Propio Joyce Pessoa ABSTRACT THE FUNCTION OF WRITING IN THE PSYCHOSIS. THE ACT OF MAKING HIMSELF A NAME OR THE ACT OF GIVING HIMSELF NAMES. SECTION V. JOYCE AND PESSOA This essay, which belongs to the investigation entitled "Language disorders and the structure of psychosis", dedicates its last phase to the study of the function of writing, with the purpose of analyzing a counterpoint between two writers: James Joyce and Fernando Pessoa, which emerges from the opposition between 2 ways of doing with the proper name. In the first case, the act of making himself a name, which devotes Joyce’s name to the study of generations of university students, who recognise the writer in him. In the other case, the act of giving himself names (the phenomenon of heteronomy), in which it is not possible to obtain the capture which would tie only one name with Pessoa’s work. Key words Proper Name Joyce Pessoa
