The text examines the relationship between metaphysics, ontology, and 'first philosophy.' The author argues against the common identification of these terms, drawing on Aristotle’s definition of the science of 'being as being' (to on he on). Since Greek philosophy identifies being with physis, and metaphysics deals with what lies beyond the physical, physis itself is revealed as a metaphysical reality. Consequently, philosophical physics (logos of physis) is inherently a metaphysical discipline and may belong to 'first philosophy.' However, Aristotle does not provide a strictly defined concept of 'prote philosophia,' leaving it to be derived from his broader treatment of the subject. While identifying metaphysics with first philosophy is possible under certain definitions, Aristotle’s Metaphysics covers topics that significantly exceed his own notion of first philosophy. The text concludes that a definitive resolution must wait until the concept of first philosophy can be precisely defined and justified through a thorough analysis of the Aristotelian framework.
