Abstract:In Mexico, the events of October 2, 1968 continue to be analyzed. The "Memorandum on Tlatelolco", offers a line of reflection to overcome the national duel of 48 years. From the field of hermeneutics, one deepens in the understanding of the poem of Rosario Castellanos, to find what is not said through the word. The study is developed from three categories of analysis: forgetting, thinking and memory. Two thematic axes are unveiled: nothingness as subject of the student movement of 1968 in Mexico; the suffering inherent in remembering painful events and the awareness of looking at our own death. These elements ratify the understanding of Rosario Castellanos as a critic of the violence that denounces social injustices. They also allow us to conclude that the inner voice of the analyzed text rehabilitates silence, forgetfulness, suffering and the agony of death, as social imaginaries of Mexican culture.
