'A chance meeting of a sewing machine and an umbrella. The impossible face-off between a whale and a polar bear. One was devised by Lautr amont; the other punctuated by Freud. Both are memorable. Why so? They certainly tickle something in us. Lacan says what it is. It's about man and woman.

There is neither accord nor harmony between man and woman. There's no programme, nothing has been predetermined: every move is a shot in the dark, which in modal logic is called contingency. There's no way out of it. Why is it so inexorable, that is, so necessary? It really has to be reckoned that this stems from an impossibility. Hence the theorem: "There is no sexual relation." The formula has become famous.

In the place of what thereby punctures a hole in the real, there is a plethora of luring and enchanting images, and there are discourses that prescribe what this relation must be. These discourses are mere semblance, the artifice of which psychoanalysis has made apparent to all. In the twenty-first century, this is beyond dispute. Who still believes that marriage has a natural foundation? Since it's a fact of culture, one devotes oneself to inventing. One cobbles together different constructions from whatever one can. It may be better ... or worse.

"There is Oneness." At the heart of the present Seminar, this aphorism, which hitherto went unnoticed, complements the "there is no" of sexual relation, stating what there is. It should be heard as One-all-alone. Alone in jouissance (which is fundamentally auto-erotic) and alone in significance (outside any semantics). Here begins Lacan's late teaching. Everything he has already taught you is here, and yet everything is new, overhauled, topsy-turvy.

Lacan had taught the primacy of the Other in the order of truth and the order of desire. Here he teaches the primacy of the One in its real dimension. He rejects the Two of sexual relation and that of signifying articulation. He rejects the Big Other, the fulcrum of the dialectic of the subject, disputing its existence, which he consigns to fiction. He depreciates desire and promotes jouissance. He rejects Being, which is mere semblance. Henology, the doctrine of the One, here outclasses ontology, the theory of Being. W
