In 1924 he began his secondary studies at the Colegio Nacional de La Plata, where he met Professor Pedro Henríquez Ureña who gave him the first inspiration for his literary career. In 1929 he entered the Faculty of Physical-Mathematical Sciences of the National University of La Plata. There he was a militant of the university reform movement in 1933, in a group with communist tendencies. In 1933 he was elected general secretary of the Communist Youth Federation. However, in 1934 he began to have doubts about communism and Joseph Stalin's regime. The Argentine Communist Party decided to send him to the Leninist Schools in Moscow for two years to prepare for a congress. Before going to Moscow as a delegate of the Communist Party of Argentina, he abandoned the congress and fled to Paris. It was there that he wrote his first novel: The Silent Fountain (unpublished). After obtaining his doctorate in physics at the National University of La Plata, he returned to Paris to carry out research work on atomic radiation. In Paris he became acquainted with the surrealist movement, studying the works of Óscar Domínguez, Benjamín Péret, Esteban Francés and others. This would have a profound influence on his future work. He returned to Argentina in 1940 hoping to leave science to continue writing. However, he found himself teaching engineering and earning a postgraduate degree in relativity and quantum mechanics at the University of La Plata. After three years he abandoned science forever to dedicate himself completely to literature and painting. If he had not been part of the general secretary of the Communist Youth Federation and had the opportunity to go to Europe, Paris perhaps would not have been an option.

We see him trying to communicate, but life right now is surreal and his ability to communicate with the world is no longer possible. “And then I felt that my destiny was infinitely lonelier than I had imagined” (152, Sábato Conclusion Ernesto Sábato's 'El Túnel' is a morbid and strange adventure into the human psyche). The life confession of the painter Juan Pablo Castel, who kills the only love of his life who understood him, personifies the novels of this period. Key factors, such as personal background and political environment, influenced the precursor to the literary "boom" in the time of Ernesto Sábato. The literary approach taken in The Tunnel helps weave together and ultimately reinforce the existentialist trend of the era..
