Jean-Michel Vappereau — La logique du fantasme et sa topologie
Written by Vappereau in Balvanera, using Boolean logic and Eulerian circles to evidence the relationship between separation and alienation constitutive of the “punch” (poinçon) in the formulas of Lacan. This paper represents the “argument” of a larger work by Vappereau entitled “La structure du fantasme (S<>a) dans la poétique d’Aristote comédie de l’Aliénation (l’Avare; Le Balcon de Genet) / tragédie de la Séparation (Oedipe)?” Two versions of this paper exist on the JMV site, both of which are uploaded here.

#12 Projective plane
The projective plane
The projective plan has been used widely by Jacques Lacan, mainly in its cross-cap presentation. What is a projective plane? Is the cross-cap the most relevant way to account for the human psyche?
On the railroad tracks:
— the discourse of the master says: “the railroad tracks are parallel”
— the discourse of the hysterical says: “I see tracks are converging toward a common point”
— the discourse of the university says: “the tracks are parallel and converge in a projective point”
— the discourse of the analyst says: “the subject is structured as a projective space”
