#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.

#19 The 4 Discourses

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. while it is present in the Latin countries, It is the rule in Anglo-Saxon countries.

#18 Sinthome, intercourse and Joyce

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.
Thanks to Gérard Crovisier who brings us his lighting.

#17 Repetitions

Automata and automatism of Repetition

How is repetition automatism a particular form of automaton? This is an attempted answer, (but not very satisfying for my taste). An example is given from a song taken from the album “Mechanical Music” by Carla Bley.
