Conversations between Jean-Pierre Petit and Jacques Lacan in 1979

 

There are the description of three conversations between Jean-Pierre Petit and Jacques Lacan. They took place in 1979 not so far from his death.

As you will see the themes of these conversations analyse the topology of the cross-cap and the Boy surface. There Lacan is focused on the points in these structures that actually do not exist but are a consequence of the immersions of a projective plane. A projective plane cannot be embedded in our 3D space (R³), it can only be embedded in a 4D space (R⁴). The interesting point is that Jean-Pierre Petit insists on the fact that these points do not exist in the reality of the structure, but Lacan still insists on these geometrical artifacts. This led to a lot of misinterpretations of this structure (Point hors-ligne, Ligne sans-points).

“Lacanalyst” an instance of non-analyst

The Lacanalyst signifier is specifically dedicated to the USA and all of the countries where the Health Departments do not want to see the difference between the Discourse of the Analyst and the discourse of the university. Here is a short description of the motives and solutions suggested.

Le schéma en L de Lacan

Je souhaiterais faire connaître mon approche en vous présentant un exercice de style: cette relecture du schéma en L de Lacan.
J’espère ainsi retenir l’attention d’une ou deux personnes avec lesquelles je puisse avancer. Peut-être en formant un groupe de réflexion?
