#16 Degrees of freedom

Degrees of liberty in the acts of the subject

We talk about choice and free will; J. Lacan showed, by mathematical examples that the choices of the present are constrained by the past of the subject. This session will continue in the workshop #17, more specifically focused on the repetition automatism

Reality & hallucination in psychosis

The passage of an object of reality into an object of desire is drastically transformed when a fundamental signifier is foreclosed. The object of reality is then transformed into hallucination.

#13 Object Reality, Desire object

From an object of reality to an object of desire

What is the proximity between the objects that our senses perceive and the conscience that we have on them? If it is very minute, then part of our objects of desire is hallucinatory.

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”

#11 Intension, extension

Psychoanalysis, pass, in intension, in extension

The pass in intension or in extension, psychoanalysis in intension or in extension, What is it when Lacan uses these terms? It seems that he uses these qualifications in a quite remote sense than the one they have in logics
