#65 Perversion #1
The term perversion, which is a Freudian concept, invades the social body. Perverse practices are as old as the world, But it is relatively recent that this term formalized at the end of the nineteenth century, be used. Also the one who undergoes perversion most often reaches the term of “amazement”. Pierre Belon takes up the history of this concept, and then Jacques Siboni evokes relations between perversion, amazement, desire, law and enjoyment.

#61 The Academic Subject and the Lacanian Subject
Pierre Belon begins where primary school teaches the notion of subject. It conveys to us how this concept crosses various semantics. This up to what Freud and Lacan taught us. In particular by this matheme “The signifier is what represents a subject for another signifier.”

#60 The Incest Barrier
“The incest barrier protects and nourishes desire”. This particularly enlightening assertion was made by Serge Leclaire on Wednesday 27 January 1965 during the first closed seminar of Dr.. Jacques Lacan whose theme of the year was the crucial problems for psychoanalysis.
During this workshop we will try with the help of Pierre Belon to analyze what this sentence conveys to us.

#59 And what about the subject for Lacan?
As a follow-up to the workshop #58 devoted to the concept of subject for Hegel, here are elements of the Lacanian conception of the subject. However, as this theme is too ambitious to fit in less than two hours, three or four relationships remained in the shadows.

Videos of Clinical and Topological Workshop
Once a month a Lacanian topological clinic workshop is held.
An important note for our English speaking colleagues, Quinn Foerch is kind enough to insert English and French duplicate subtitles with each session of the workshop. They can be spotted by the brown color of their title below. However, these subtitles are only accessible in the YouTube version of the sessions.
The sessions of the topology workshop on the site Lutecium
-
- #01 The syntactic structure Syntax doesn't lie
- #02 relationship meaning / meant in the slip The bar is a Moebius strip
- #03 Articulation and mismatch between demand and desire #1: The graph “Do not ask for your way to the one who knows it, you might not get lost.”
- #04 Articulation and mismatch between demand and desire #2: An embrace “I demand you to reject what I am offering to you, because it is not that”
- #05 Pulse topology How do unite and separate subject and desire. The libido is just like bubble gum
- #06 Real, Symbolic, Imaginary The three dimensions of speech. These dimensions are also dits-mansions where the object comes to nestle
- #07 Anguish, Inhibition, Symptom The course from anguish to symptom. How the symptom and its secondary benefit coexist
- #08 The Sinthome The construction of sublimation by the sinthome
- #09 The transference along the course of analysis. A sequel to the sinthome by Gérard Crovisier and a disappointing recording on transference and the desire of the analyst
- #10 Pass or Passes? The Pass is not limited to an institutional procedure; with the participation of Fanny Jeandel
- #11 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 he uses these adjectives in a distant sense of those they have in logic
- #12 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?
- #13 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.
- #14 Reality and hallucination in psychosis. The transformation of an object of reality into an object of desire is substantially transformed when a fundamental signifier is foreclosed. The object of reality is then transformed into hallucination.
- #15 The phallus object and the one who possesses it. The phallus, object so different from the penis, has among other particularity, of only being able to be possessed by one at any given time. What does it confer to the possessor and to the one who is lacking?
- #16 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.
- #17 Machines and automatism of repetition. How is repetition automatism a particular form of automaton? This is an attempted answer, (not very satisfactory for my taste). An example is given from a song taken from the album “Mechanical Music” by Carla Bley.
- #18 Sinthome and sexual intercourse for Joyce. The sinthome, this process of sublimation described by Lacan, takes a very special form in James Joyce. This crystallizes in an unusual relationship with the other sex, a form of folie à deux.
- #19 The four discourses. Discourse of the master, of the hysteric, of the University, and the analyst; these 4 modalities of discourse structure our intersubjectivity. A frequent drift in the analyst's discourse pushes him towards discourse of the university.
- #20 The logic of fantasy #1: The negations or “So long, I do not hate you” The logic of fantasy, very dense and complex seminar Jacques Lacan. We approach a first part which describes four varieties of negations used by the subject in his relations with his objects of desire..
- #21 The logic of fantasy #2: The Klein group or “Either not-I think, or not-I am”. The logic of fantasy. What is the use made by Lacan of the Klein Group? Especially the connections with repetition, the passage to the act, acting out and sublimation.
- #22 The logic of fantasy #3: D’or name The golden proportion and its Lacanian interpretation, Aristotelian categories, and the use of science by psychoanalysis.
- #23 The logic of fantasy #4: The first Other is the real body. Then it is pierced by a signifier which inscribes its indelible mark on it.
- #24 Le Polygone Fondamental. The fundamental polygon allows to display in a rectangle structures such as sphere, the ring of Moebius, the cylinder, the disc, the projective plane, the torus, the Klein's bottle.
- #25 The logic of fantasy #5: The Trou-matism. Rewriting the constitution of the Real by associating Symbolic and Association, the trauma that leaves a hole, the hole-matism.
- #26 Nodal topologies of the object has. The number of consistencies (number of rounds of string) conditions the structure. Paranoia, schizophrenia, and sinthome, neurosis, fantasy.
- #27 The power of the signifier. Topologies of the object a. "I kill seven with one blow" It is through this signifier that inaugurated the tale of Grimm Brave Little Tailor. The signifier carries a specific power.
- #28 Four threads nodes, a sinthome. A discussion around the four Borromean knot and the sinthome, with some disagreements on the possible and the impossible of transformations
- #29 Topological manipulations. Manipulations of knots, strands and surfaces. A disputation where are discussed different structural designs of nodes. Topological objects are confronted with the psychoanalytic clinic.
- #30 Moebius strip and projective plane. Articulation between the structures of the Moebius strip and the projective plane.
- #31 Without the knowledge of my own volition. “I did it without the knowledge of my own volition!” How many syllables in a signifier? How to name a missing signifier? What is the nature of the skin separating signifier and signified? And separating truth and knowledge?
- #32 A tetravalent logic. The logic of the subject is tetravalent. The standard logic, called Aristotle logic, uses the principle of the excluded third. This logic is not compatible with the subject. It is necessary to use logic with four truth values.
- #33 Real with cylindrical structure. The clinical consequences of a cylindrical structure of reality. The moebien real of Lacan may be constructed out of a cylinder. Using this structure it is often easier to explain the relation of the subject with its objects of desire; this as well in the case of "normality", neurosis, Psychosis.
- #34 Cutting up a sphere. Gerard Crovisier performs carvings made on the sphere and discusses their clinical consequences. From time 1:01:23 we return to some questions that emerged as a result of the workshop #33.
- #35 Empty torus? solid torus? When Lacan evokes the torus is it a toroidal surface (an air chamber) or a solid torus (un donut)?
- #36 Neighborhoods, Graph, Graph of desire Resume topological definition of Neighborhood. Definition and example of the concept of finite states graph. The Lacan graph of desire.
- #37 Logics and Aristotle. Aristotelian logic is redescribed especially in its relations between intension ( categories, types, …) and extension (the individuals, instances, …). Gerard Crovisier connects these logics to the clinic of the subject.
- #38 Formulas of Sexuation. What differentiates the male and the female part? Why Lacan says that there is no sexual report/relationship? And that THE woman does not exist? .
- #39 Formulas of Sexuation #02. Back to the formulas of sexuation. Many issues needed clarification.
- #40 Chaos and Rule 30. Following a presentation to La Lysimaque I develop the concepts of chaos and in particular Rule 30 describing what characterizes dynamical systems when being chaotic.
