In 1924 he began his secondary studies at the Colegio Nacional de La Plata, where he met professor Pedro Henríquez Ureña, the first source of 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 active in the university reform movement in 1933, in a communist-leaning group. In 1933, he was elected general secretary of the Communist Youth Federation. However, in 1934 he began to have doubts about communism and the regime of Joseph Stalin. The Argentine Communist Party decided to send him for two years to the Leninist schools of Moscow to prepare for a congress. Before going to Moscow as a delegate of the Argentine Communist Party, he abandoned the congress and fled to Paris. It was there that he wrote his first novel: The Silent Fountain (unpublished). After obtaining a doctorate in physics at the National University of La Plata, he returned to Paris to carry out research on atomic radiation. In Paris, he discovered the surrealist movement by studying the works of Óscar Domínguez, Benjamín Péret, Esteban Francés and others. This will 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 doing a postgraduate degree in relativity and quantum mechanics at the University of La Plata. After three years, he definitively abandoned science to devote himself fully to literature and painting. If he had not been part of the General Secretary of the Communist Youth Federation and had not had the opportunity to go to Europe, Paris might not have been an option.

We see him trying to communicate, but current life is surreal and his ability to communicate with the world is no longer possible. “And then I felt that my destiny was infinitely more solitary than I had imagined” (152, Sábato). Conclusion “El Túnel” by Ernesto Sábato is a morbid and strange adventure into the human psyche. The life confession of the painter Juan Pablo Castel, who murders the only love of his life who understood him, personifies the novels of that era. Key factors, such as personal background and political environment, influenced the precursor to the literary "boom" in the era of Ernesto Sábato. The literary approach adopted in The Tunnel contributes to weaving and ultimately strengthening the existentialist tendency of the time..
