This article presents an analysis of the temporal dimension of a psychoanalytical concept called lack-of-being using elements of Heidegger’s existential analysis he describes in Being and Time. Based on that, we discuss the function of the cut, which reveals the subject as discontinuity in the real, as proposed by Lacan in his seminar Desire and its interpretation. To conclude, the category of the cut is proposed as the technical corollary of the ontological proposition of lack-of-being and the way to operationalize the politics of psychoanalysis in its relation to the temporality of the treatment.
