The writing of Lacan's discourses is made up of elements (letters), places (quadrants) and functions (logical operators). Each of these discourses formalized by Lacan is composed by the peculiar distribution of these letters in these places and functions. Lacan established, in this way, his own structure for each of the four discourses: the psychoanalytical discourse, the master discourse, the hysterical discourse and the university discourse. Lacan's logical construction was analyzed - mainly in Seminar 17, The contrary of the Psychoanalysis - for each of these discourses, highlighting their consistencies, approaches and contrasts. The purpose of this paper is to demonstrate how the appropriate consideration in Lacan's discourses can be an important psychoanalytical approach of the subject by means of its discursive universe.
