Style as Hallmark of Intellectual Freedom: philosophising according to Cornelio Fabro (paper in Italian): Cornelio Fabro (1911-1995) was an Italian Catholic priest of the Stigmatine Order and a scholastic Thomist philosopher and theologian. His deep contributions to the study of St. Thomas Aquinas’ philosophy are to be regarded as the most relevant with respect to the notion of “participation”, which he demonstrated to be fundamental within Thomas’ ontology and metaphysics. However, the very wide range of his philosophical, scientific and cultural knowledges were far limited to Scholastic Philosophy. He was expert in modern and contemporary philosophy (e.g. he wrote one of the most valuable and large monography on the origins and developments of atheistic thought, along with being the Italian translator of the Danish philosopher Kierkegaard: by the way, he was fluent in English, German, French, Spanish, Danish), but he was also a biologist and a refined organo player. Not surprisingly he was awarded with an impressive series of cultural titles by the Vatican and Italian State and by other public and private institutions. In front of such a giant of culture in this paper I try to investigate his peculiar philosophical methodology and style, which were animated by the most pure tension to the discovery of truth and, as a consequence, by a real intellectual freedom.
