This dissertation seeks to investigate the notion of style in Lacanian psychoanalytic theory. Two questions will guide our research: (i) how may we understand the idea of style according to Lacan; (ii) in which manner does this notion relate to the psychoanalytic clinic as well as the teaching of psychoanalysis Considering these queries, two hypotheses will guide our investigations. Firstly, the notion of style, as it was approached by Lacan, seems to differ from its common conception, whereby it is frequently thought of as a choice relative to form. The novelty introduced by Lacan regards the fact that he associated style to his concept of object a, and not to the idea of subjectivity. Secondly, having the object a as its determining element, style may be thought of as a way of including, in discourse and in writing, that which cannot entirely be transmitted through signification and understanding alone. In our first chapter, we will study some of the main the historical developments of the notion of style, in Literary theory and in Philosophy, and compare them to the changes of this notion, found in Lacan s work. This path will allow us to establish the specificities pertaining to the idea of style according to Lacan. In our second chapter, we will investigate the object a, in relation to the subject s constitution. Only then will we attempt to define the relations between object, pulsion and repetition. Our aim, at the end of this chapter, is to study what changes in relation to the object and to pulsion at the end of the process of psychoanalysis – as approached by Lacan in the decade of 1960 –, as well as the possible effects that this process could have on style. Finally, in the third chapter, we will investigate the relation between style and transmission in psychoanalysis, leading us to the idea that there’s always something illegible in the psychoanalytical experience, which can be conveyed but not taught.
