This article focus on the notion of silence under the perspective of the psychoanalysis. Several are the references that lead us to verify the double statute of the silence - the clinical "procedure", the "formulations" of the lacanian psychoanalysis, the literature of Clarice Lispector, the linguistic theory of Eni Orlandi. The aim is to judge this duplicity, linking one silence to the notion of emptiness and the other one to the notion of absence. For such differentiation, is used the resource of the mathematical notion of zero and -1 (minus one)
