His good academic results determine his dedication to studies and teaching, for which he was sent to various Central European universities to complete his theological, philosophical and scientific training.

The thirties are characterized by a progressive separation from his ecclesiastical studies, a process exacerbated by the Civil War and exile.

He graduated in philosophy from the University of Barcelona in 1934, reaching his doctorate a year later with the thesis Essay on the logical-genetic structure of the physical sciences.

As a member of the Vienna Circle (1934-6) he taught mathematical logic and philosophy of science at the University of Barcelona between 1933 and 1937.

In February 1936 he obtained the chair of Introduction to Philosophy at the University of Santiago de Compostela, but he did not exercise it since he had to leave Spain precipitously due to the start of the Civil War.

In that year, when the ecclesiastical authorities ordered him to return to Franco's Spain where he risked being tried and even shot because he had identified himself as a republican and was prohibited from publishing his writings, he decided to reveal himself.

In his work Confessions: intimate and exterior autobiography he comments as follows:One day [October 26], after lunch, at noon, I knelt down and asked the community for forgiveness for the bad examples I had given, while thanking them for their fraternal and generous hospitality.

I went up to my cell, took off my cassock, hung it in the closet; I dressed fully as a layman, took my suitcase, went downstairs; but instead of going through the goal, I went out through the church.

[2] He was critical of the Francoist uprising, which is why he remained in Paris during the hostilities, years in which he devoted himself to logic, to go into exile, after the war, in Ecuador (1939–42), Mexico City, Morelia, (1942) and finally in Venezuela, where he has established residence since 1946.

So that the Spanish civil war ended with victory for Franco, García Bacca opted for the tropics of America.

Upon arriving in the equatorial capital, already hired as a professor in the Philosophy section (which he himself inaugurated) of the Higher Institute of Pedagogy and Letters, he established a great friendship with Alfredo Gangotena.

87–88) In Caracas (Venezuela) he had a fruitful philosophical career when he was the founder of the School of Philosophy of the Central University of Venezuela (UCV) in 1946 ―which was the first school of the Faculty of Philosophy and Letters, today the Faculty of Humanities and Education―, remaining active until 1971.5 At the same time, he taught at the Pedagogical Institute of Caracas (1947-1962).

His work at the UCV was very active: he was dean of the Faculty of Humanities and Education (1959-1960) and founding director of the Institute of Philosophy.

He influenced the formation of Ernesto Mayz Vallenilla, Juan Nuño Montes, Ludovico Silva, Federico Riú, Eduardo Vásquez, J.R. Nuñez Tenorio, Elio Goméz Grillo, Guillermo Morón, Ignacio Burk, Alexis Márquez Rodríguez, J.R. Guillent Pérez and José Hernán Albornoz.

Bacca chose Ecuador as his final resting place, the Tumbaco valley, on the outskirts of Quito, where he spent his last years in the company of his wife, the Ecuadorian Fanny Palacios, his daughter Anita, his son-in-law Eduardo Pólit and the grandchildren Pólit García (until his death in 1992).

His contributions have been overlooked partly because his enunciation space was a Latin American country, misnamed underdeveloped, and partly because his risky metaphorical and aphoristic prose, and even poetic, mathematical and musical, sometimes contradictory, left encrypted "philosophical instruments", as he used to call them, for later generations.

Something like the new exaltation of a superior, scientific-technological religion that the author proposes to call "radioanthropology", because as he explains, that is the force that impels man to transfinitude or escape from his natural and bodily closure."

By the way García Bacca declares:Life, the living being, in body and fortiori in soma is, and fortunately has to be, a supplier of novelties, an improviser of spontaneity, a premiere of originality; radiontological, radioanthropological, in occurrences, wits, thanks, wits, tricks, inventiveness, evasiveness, surprises, admiration, and improvisations.His work as an educator and philosopher was the subject of innumerable distinctions.

That same year in Caracas, his name was given to the Library of the Institute of Philosophy and the Juan David García Bacca Chair was created in the Faculty of Humanities and Education of the university.

Received from the Venezuelan government the Grand Cordon of the Order of the Liberator, a highest official distinction of the country from 1983.
