Archival Overview
Phoenician-born Neoplatonist philosopher who edited and published Plotinus's Enneads and wrote the Isagoge, whose 'Tree of Porphyry' became the standard introduction to logic for over a millennium.
Biographical Record
Born Malchus in Tyre, Porphyry (c. 234–305 CE) studied in Athens under Longinus before joining Plotinus in Rome in 262. He edited Plotinus's scattered treatises into six books of nine treatises each, titled the 'Enneads', accompanied by a biography of his teacher.
Porphyry authored the 'Isagoge' ('Introduction'), a commentary on Aristotle's Categories that introduced the famous Tree of Porphyry (arbor porphyriana), illustrating division by genus, species, and difference. His questions in the Isagoge sparked the monumental medieval debate over universals (realism vs. nominalism).
