Levi's lucid, non-ideological and sympathetic description of the daily hardships experienced by the local peasants helped to propel the "Problem of the South" into national discourse after the end of World War II.

[1] Levi never completely abandoned his medical studies and served as assistant to Professor Micheli at the University of Turin's Clinic from 1924 to 1928, working on research involving hepatopathy and diseases of bile tract.

Levi's early time in Paris, as a painter and as a student of medicine, brought him into contact with many notable personalities of the 20th century, including Sergei Prokofiev, Igor Stravinsky, Alberto Moravia, Giorgio de Chirico, and others.

[2] In 1929, along with Carlo and Nello Rosselli he founded an anti-fascist movement called Giustizia e Libertà, becoming a leader of the Italian branch along with Leone Ginzburg, a Russian Jew from Odessa who had emigrated with his parents to Italy.

As a result of his activism and involvement with anti-fascist movements, Levi was arrested and exiled to Aliano (Gagliano in Cristo si è fermato a Eboli) and Grassano, two towns in a remote area of Italy called Lucania (now Basilicata) from 1935 to 1936.

His written works include L'Orologio (The Watch) (1950), Le parole sono pietre (Words Are Stones) (1955), and Il Futuro ha un Cuore Antico (The Future has an Ancient Heart) (1956).
