Marías was born in the city ofValladolid, and moved toMadrid at the age of five. He went on to study philosophy at theComplutense University of Madrid, graduating in 1936. Within months of his graduation theSpanish Civil War broke out. During the conflict Marías sided with theRepublicans, although his actual contributions were limited to propaganda articles and broadcasts.
After the end of the war in 1939, Marías was imprisoned for several months on false charges, and was unable to carry out university teaching activities after his release. His doctoral thesis was rejected due to the committee's animosity towards someone who was a disciple of Ortega. In 1940, hisHistory of Philosophy was published — his first work published after the civil war — and although it ended up being a great publishing success, it led him to go through a period of financial difficulties due to his being banned from teaching by theFranco regime, and so Marías instead supported himself with private classes and translations.
In 1948 he co-founded, along with his former teacher José Ortega y Gasset, the Instituto de Humanidades (which he went on to head after the death of Ortega in 1955). Between the late 1940s and the 1970s, being unable to teach in Spain, Marías taught at numerous institutions in theUnited States, includingHarvard University,Yale University,Wellesley College,the University of Oklahoma, andUCLA.
