New Argentinean generations do not know Rodolfo Ortega Peña. It is logic that it is like that, though it evidences the profound social break with the historic process. This disregard for Ortega Peña is inscribed in a huger and more general disregard. The exercise of oblivion in which Argentineans have been condemned since March the 24^th of 1976 till today and the devices developed towards past obliteration with the interested exercise of oblivion are part of the efforts to hide two intense decades. Besides, oblivion is not only memory derogation. It tends to replace it by a mythical narration of past: silence has given way to counterfeit normalization ways, through an official interpretation.
