#45 A cosmogony compatible with the subject's structure of the unconscious?
Elements of the topology of the cosmos by Jean-Pierre Petit, the Janus model are presented by Gérard Crovisier. The unexpected is, except for one detail, This model joins the conception of the subject that we taught us Jacques Lacan. So there are two parts; in the first half-hour Gérard Crovisier explains this cosmogony; in the following I will take up the structure of the real, the symbolic and the imaginary according to J. Lacan, and the few inflections which invoke compatibility with the model invented by Petit and its consequences at the clinical level.

#43 Movements in four discourses
An oriented tetrahedron makes it possible to explain the movements present in the discourses about the master, on the hysterical, on the university and on the analyst. Also some remarks on the refusal of the Catholic Church and the Lutheran Reformation to recognize heliocentrism.
Henry Fontana gave me his approach to the life and death of Giordano Bruno. I had not read the text he sent me on this topic and therefore I said several wrong things. Here is his text:
In 1600, Robert Bellarmin, Jesuit, presides over the tribunal of the Inquisition which condemns and has Giordano Bruno executed by the stake.
R. Bellarmine had designated himself as the “hammer of heretics”.
In 1616, during the Galileo trial, still president of the Inquisition tribunal, he threatens Galileo and reminds him of what he himself had stated in 1600 during Giordano Bruno's trial, namely the formal ban on teaching heliocentrism “anywhere and in any way” (teach in any way whatsoever) under penalty of being condemned for heresy.
Robert Bellarmine was declared a saint by the Church in 1930.
In 1600 after the conviction of Giordano Bruno, Galileo and Kepler had written a joint testimony: they recognized that they themselves had not sufficiently supported their colleague!
I spoke of Luther when it was about the Calvinists known as Huguenots in Switzerland while the Lutherans are on the Germanic side. Calvin had since died 1564.
I apologize to Henry!

#42 Mass psychology
Sigmund Freud, quoting Le Bon, marks the subject, member of the masses, the seal of barbarism. Michel Roussan analyzes Freud's text “Mass psychology and ego analysis” of 1921 and attach this work to the structure of the four speeches invented by Jacques Lacan. The connections with our present time cannot be avoided.

#41 The master, the slave, the university, Science
“The slave is defined by the fact that someone has power over his body” told us Jacques Lacan. The master needs tools to ensure the docility of the slave. In the past it was the whip, the rifle, the police, judges etc. Nowadays new tools are at his disposal, Science, mass media, the police, Internet, the LBDs, the fines, the judges, etc. In the past, these tools formatted the slave, the sufferings, fear of death, the feeling of inferiority, etc. Today is the fear of tomorrow, fear of mutilation, fear of illness and death, infantilization, guilt, etc. We propose to find the dialectic of master and slave in the master's discourse that Lacan taught us, and to find in the discourse of the university the tools that the teacher uses as tools of enslavement.

#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.
I was not certain that this session of the workshop has little to do with the psychoanalytic clinic, but to our surprise, connections occurred.

A general equation for all links and knots
This disputation follows, and amplifies , the intervention of Michel Thomé at the last Saturday of Lysimaque.
We return to the definitions and characteristics of links and knots.
Then Michel Thomé describes the equation he produced, for writing each knot and link. And from this equation we can write the equation of the next link and of the previous one. It seems that this is a general equation for encoding all of the possible links.

Videos of Topologos-Lutecium Disputations
We produce recordings of meetings between two or three people who “dispute” about an object.
Word Disputation does not exist in French but is found in Latin and English.
“Disputatio” in Latin, definition in Gaffiot dictionary:
Action to examine an issue in its different points, weighing the pros and cons, discussion, dissertation; computation.
“Disputation” in English; definition of “The American Heritage Dictionary“:
