From the history of logic. Semantics of homonymy in Porphyry’s logic

The article deals with the logical and semantic aspects of the theory of homonyms in Aristotle's “Categories” within the context of Porphyry's commentaries. We consider the logical formation of the doctrine of homonymy of nouns, verbs, and conjunctions in Ancient Greek. We reveal the difficulty in interpreting the terms “κατηγορίαι”, “?νομα” and “??μα”. The paper has shed some light on different aspects of Porphyry's logic.
