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?

Topologies of the object a

Among the topological considerations of the object a, We focus today on its nodal approaches. The number of consistencies (number of rounds of string) conditions the structure.

  • One consistency: the knot of the paranoid
  • Two consistencies: the knot of the fantasy
  • Three consistencies: the knot of neurosis
  • Three unwound consistencies: schizophrenia
  • Four consistencies: the knot of the sinthome

The fundamental polygon

Lacan has accustomed us to display the constituents of the subject on topological structures. Here for the sake of simplification (!) We present these structures in a singular way, a rectangle. It's the fundamental polygon.
This concerns the sphere, the ring of Moebius, the cylinder, the disc, the projective plane, the torus, the Klein's bottle. A consequence is that this session is rather austere …

The logic of fantasy #4 The first Other is the real body

This is the fourth workshop on the seminar The logic of fantasy. The very first Other is the real body. Then it is pierced by a signifier which inscribes its indelible mark on it.
The number Lacan uses is not the golden proportion, let's name it “the Lacan's Number”
Many hesitations but a small finding (for me) …

#21 Klein's group #2

The logic of fantasy #2 The Klein group or “Either not-I think, or not-I am”

The logic of fantasy, very dense and complex seminar Jacques Lacan. Here's the second part of this workshop. We try to understand the use Jacques Lacan made of the structure of the Klein group. Especially the connections with repetition, the passage to the act, acting out and sublimation.

#20 Logic of fantasy #1

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.. (Warning a failure of the camera which forced me to re-record this workshop! Too bad.)
