Abstract

This article is devoted to the interpretation of the object of metaphysics and theoretical sciences proposed by Alexander of Aphrodisias (fl. 200 AD). I shall propose two conjectures on crucial passages from his commentary on the Metaphysics (In Metaph. 245.37-246.6 et 246.6-13) and, on this new textual basis, defend the thesis according to which Alexander articulated a primary fundamental philosophy, devoted to immobile substances and treated by Aristotle in Metaphysics Λ, and a philosophy, if one can say so, more primary but less ontological, hence less fundamental, devoted to the general structure of being and treated by Aristotle in Metaphysics Γ. The latter seems to differ from the Categories, according to Alexander, in that in the Categories, Aristotle studies the general classes of beings as general, while in Metaphysics Γ, he studies them as beings.
