ABSTRACT:
The article aims to demonstrate how the aphorism Yad’lun, forged and worked out by Jacques Lacan, notably in the seminars The psychoanalyst’s knowledge and …or worse between 1971 and 1972, is the basis for the theory of sexuation promoted, at that time. We discussed how the epistemological ruptures involved in the One lead to the writing of the impossibility of sexual proportion for the speaking being. The aphorism unfolds therefore in: there is no relationship between the One and the Being, the One and the Other, the One and the Other sex, that is, there is no sexual relationship.
