ABSTRACT
The lapsus of the knot is to psychoanalysis what original sin is to the Christian religion, with one small difference: Lacan formalises his concept with the support of the Borromean knots, while religion relies on a supposition. The fundamental lapsus is what opens up different modalities of reparation. The unconscious is verified in the knot with the symbolic and the imaginary, if authors were to consider the advance made in Encore, for there Lacan defines both the unconscious and the speaking being in the same sentence. Just as there is no subject without the relation to the unconscious structured like a language, so there is no speaking being without the relation to the unconscious designated as a cohabitation with lalangue, that is, with the singular modality of the jouissance of the unconscious. It is important to grasp the way in which Lacan defines the terms unconscious and sinthome.
