What is the scope of Aristotle’s defense of the PNC? (English) Zbl 0993.01003

The author deals with Aristotle’s argument in defense of the principle of non-contradiction (PNC) especially as presented in the so-called ‘elenctic proof’ in Metaphysics \(\Gamma\) 4, 1006a11-34. He holds that the scope of this version of the PNC should not be restricted to substantial and essential predication, but also to predications of accidents, properties, transcategorials, or aggregates. He unfolds his position in arguing against opposing views of E. Anscombe (pt.1) and T. Irwin (pt. 2).
