TONGIORGI, SALVATORE. – Philosopher, born in Rome on 25 December 1820, died there on 12 November 1863. He entered the Society of Jesus in 1837. He was professor of philosophy at the Collegio Romano from 1853 until his death.
His Institutiones philosophiae (3 vols., 1861) and Institutiones compendiariae philosophiae moralis (1863), notable for their solidity of doctrine and clarity of exposition, met with favor and went through numerous editions. Nevertheless, influenced by the thought of his time, he departed from scholastic doctrines on not a few questions of ontology, cosmology, and psychology. The best part of his work is the Logica, which includes an excellent treatise on dialectics, placed before the major logic.
