Cutting up a sphere

Gérard Crovisier shows cutting ups made on a sphere and their implications in clinic.

Also starting at time 1:01:23 we review some questions that emerged as a result of the workshop #33.

The consequences of a cylindrical structure of real

Returning to the Lacanian presentation of schema R applied to a cross-cap he considers the real to have a Moebius strip structure. Without changing this paradigm it is possible to build it 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.

The logic of the subject is tetravalent

The standard logic, called Aristotle logic, uses the principle of the excluded third. I.e a proposition is either true or false. However, by a closer look as did Godel, Husserl, Lacan and many others, we see that some cases invalidate this approach by revealing a part of undecidable. The logic must integrate its share of incompleteness. There are propositions that may be true and false, or neither true nor false. These modified logic elements could remain on purely mathematical fields. The analytical listening uncovers that much of the discourse of the analysand enters into this logic of four truths values. We describe this tetravalent logic in its mathematical approach and clinical approach.

Topologies of the object a

“I shoot 7 on a single strike” It is through this signifier that the tale of the Valiant Little Tailor of Grimm opens. We illustrate how a signifier is the bearer of a special power. What can be induced for each signifier?
