Antiphasis as Homonym in Aristotle

Antiphasis is a case of core-dependent homonymy, and has three significations in Aristotle's philosophy: (1) Antiphasis as an opposition between propositions (a propositional signification); (2) Antiphasis as the opposition between ‘subject’ and ‘not a subject’ in coming-to-be and perishing (an ontological signification); and (3) Antiphasis as the opposition between possession and privation (an ontological signification). Argument based on the fifth type of priority described in Cat. 12 shows that, for Aristotle, the ontological significations are prior to the propositional.
