ABSTRACT
Jacques Lacan himself did not fail to question his own trajectory and to reappraise each one of his steps. The new formulas as well as the theses of this reappraisal are striking theoretical rectifications. The trouble with chronology is that the enunciation driven out through the door returns through the window and no less so than in the authorised argument. It is true that he explored the structuralist path methodically, seeking to establish that the unconscious belongs to a rational order that has its own laws. By hypothesis, linguistics and structural anthropology, which take as their object the compositional laws of the structures that concern them, posit a subject who is no more than the pure subject of a combinatory. That Lacan's first formulations can be resituated in the vocabulary of the Borromean knot shows us that with the knot Lacan was on the path to a more inclusive schematisation, one which allows both neurosis and psychosis.
