The appearance of the notion of a lack in the Other corresponds, in Lacan's work, to the fact that the specificity of psychoanalytical thought obliges the theory to assimilate the impossibility of a totalizing structure that, completely overwhelming the subject, would turn it into a kind of epiphenomenon of the signifier. The paper has the aim of providing some guidance for the understanding of this movement especially as it crosses the levi-straussian approaching of structure. In order to do this, it will follow two axles: the first one is the idea that there is nothing within discourse that is capable of functioning as a guarantee of discourse and the second that of the prevalence of an empirico-transcendental duplicity in the concept of Other.
