On 7 March 2025, Guy Briole presented a lecture on Jacques Lacan's First Writings entitled: What do they teach us? His presentation calls for a return to Lacan's First Writings, almost 100 years after their publication. What do these texts teach us today? Thanks to the questions posed by the speakers during Guy Briole's presentation, Lacan's thinking is explored in terms of clinical knowledge. The uniqueness of the case, its singularity, and clinical detail prevail in this presentation.
