The register of the moment directly poses the question of désirance and its influence in the process of subjectivation. Starting with the problem of the encounter in the libertine, the author offers an exposé of relational issues at the onset of the genital phase. The register of consensual defeat instigates the creation of an amorous, masochistic self on which the subjectal evolution will in part depend. The moment – through the effect of divestment it introduces into the encounter, but also through the effect of putting into perspective it gives rise to – gives potential to this operation which determines the genital subject.
