As an introduction and starting point for debate, I'll post an obituary on Jacques Lacan by Alain Badiou, published in 1981, shortly after Lacan's death in the Journal 'Le Perrouquet'. Taken from the 'Pocket Pantheon', Verso Books 2009.
Jacques Lacan (1901-1981)
The man who has just died was all the greater in that greatness is becoming rare - very rare - in our uncertain lands. The media let him see that very clearly, as their goal is always to align that which exists with the transient and limited prose of journalism. They all asked his sworn enemies and those who go through the dustbins to say something about him.
Forr not even death can silence envy, it really is a sign of just how barbaric our societies are. All those psycholanalytic dwarves, all those gossip columnists amplifiying the mean cry of 'He was standing in my way, and now he's dead at last. Now pay some attention to ME!'.
It is a fact that Lacan was on a warpath right from the start, denouncing the illusory consistency of the 'Ego', rejecting the American psychoanalysis of the 1950s which proposed to 'reinforce the ego' and thereby adapt people to the social consensus and arguing that, because it is symbolically determined by language, the subject is irreducibly the subject of desire, and as such cannot be adapted to reality, except perhaps in the imaginary.
Lacan in effect established that the cause of desire is an object that has been lost, that is lacking, and that, being articulated under the symbolic law, desire has no substance and no nature. It has only a truth.
He made money out of this particularly bleak vision of psychoanalysis, in which it is the truth and not happiness that is in play, thanks to the practice of what were sometimes very short sessions. The crucial and non-existent role of psychoanalysts in the plural is to let shine - with a searingly subjective brightness - the signifier of a break that lets slip the truth of desire, whilst the individual psychoanalyst must, ultimately, reconcile himself to be nothing more that what is left at the end of the analysis and when that work is done.
The practice of short sessions polarized a real hatred of the truth against Lacan. A a result, he was literally excommunicated by the psychoanalytical International. The need to organize the transmission of his thought, and to train anaylsts who would act in accordance with what he believed to be the ethics of psychoanalytic pratice, led him to found his own school. But even there, the splits and dissolutions were testimony to a stubborn reluctance to hold the severe position he promoted to the end.
It had become good form to state that the ageing Lacan was no longer transmitting anything worthwhile from the 1970s onwards. In my view, it is quite the opposite. Having lamented the theory of the subject's subservience to the signifiyng rule, Lacan made one final effort to pursue his investigation into its relationship with the real as far as he could. The rules of the signifier were no longer enough. What was needed was some kind of geometry of the unconscious, a new way of representing the three agencies (symbolic, imaginary, real) in which the subject-effect is deployed. Lacan's recourse to topology was an internal requirement born of this new stage in his thinking, and it brought out his underlying materialism.
Lacan held that politics has no effect on the real. He used to say that 'the social is always a wound'. And yet it so happens that even a Marxism in crisis cannot avoid making reference to the dialectic of the subject the he outlines. It is in effect clear that the fiasco of the Party-States that emerged from the Third International opens up radical questions about the essence of the political subject. Now, neither the subject-as-consciousness (Sartre's thesis) nor the subject-as-natural substance will do. The at once divided and errant subject theorized by Lacan in his own realm does offer us a way out of that impasse. For such a subject is a product of a break, and not of the idea that it represents a reality, not even that of the working class. For today's French Marxists, the function of Lacan is the function that Hegel served for the German revolutionaries of the 1840s.
Given the trite situation in which we find ourselves, marked by platitudes and relative self-abasement of our intellectuals, the death of Lacan, coming so soon after that of Sartre, does nothing to improve matters. We were anxious to hear what he might still have to say. Quite aside from the content of his teaching, he developed an ethics of thought that is now highly unusual.
Le Perroquet will of course come back to almost incalculable import of that ethics. For the moment, the important thing is, without any restrictions or any presumption, to pay tribute to one who is no longer with us.
