There is a very deep tension that exists at the heart of Aristotle’s metaphysical system in virtue of the fact that his works seem to contain two distinct and not obviously commensurate ontologies: an early ontology that Aristotle outlines in the Categories and a later ontology that he develops in his physical–metaphysical treatises. In this paper I briefly describe the two ontologies, discuss the sources of conflict and outline different scholarly speculations about the relationship between the two.

Simplicius’ Commentary on Aristotle’s Categories contains the most extended testimony about the Stoic conception of acting (ποιεῖν) and undergoing (πάσχειν). Simplicius ascribed to the Stoics the idea that acting and undergoing are to be reduced to the movement. To this opinion Simplicius opposed the Aristotelian view according to which acting and undergoing are two different categories. In this paper I intend to outline the original Stoic position comparing the reportage of Simplicius with other Stoic sources. Later, I will deal with (...) Boethus’ defense of the distinction between the categories of acting and undergoing. I will argue that Boethus directly reacted against the Stoic opinion reformulating it in Aristotelian language.

This paper lists and examines the explicit references to Aristotle’s Topics in the Greek Neoplatonic commentaries on the Categories. The references to the Topics by Porphyry, Dexippus, Ammonius, Simplicius, Olympiodorus, Philoponus and David are listed according the usual prolegomena to Aristotle’s works. In particular, the paper reconstructs David ’s original thesis about the proponents of the title Pre-Topics for the Categories and compares Ammonius’, Simplicius’ and Olympiodorus’ doxographies about the postpraedicamenta. Moreover, the study identifies two general trends. The first one (...) is that all the commentators after Proclus share the same general view about: the authenticity of the Topics, Aristotle’s writing style in them, the part of philosophy to which they belong, their purpose, their usefulness and their place in the reading order. The second one is that whereas Porphyry, Dexippus and Simplicius use the Topics as an aid to understanding the Categories, Ammonius, Olympiodorus and David do not. (shrink)

One of the main difficulties that Neoplatonic commentators of Aristotle face is the different treatment that the Categories and the Metaphysics offer to the question of the substance. After describing briefly the status quaestionis ousiae in Aristotle, and after tracing the main Neoplatonic interpretations of this doctrine, this article attempts to demonstrate that the Neoplatonists of Athens and Alexandria, Syrianus and Ammonius, inaugurate a new interpretation of the Aristotelian doctrine. With regard to the category of substance in general and to (...) the question of substantiality of “immanent form” in particular, this new interpretation goes beyond the positions of Plotinus and Porphyry and returns the ontological value to the Aristotelian substances. Unlike Plotinus, who recognized as ousia only that one intelligible, that is five genres of the Platonic Sophist, and unlike Porphyry, who defused the anti–Platonic fuse of the Categories, giving to this treaty a mainly semantic skopos, these philosophers, through their original study of the theory of the three states of katholou, already shed in the Porphyrian Eisagôgê, fit the immanent forms of Aristotle, recognized as substances and as a reflection of the transcendental universal, into the late antique Neoplatonic metaphysical triadic structure.

The claim that metaphysics is fundamental has frequently been voiced in the history of the discipline. However, the usual ways in which this claim is justified do not appear to be effective. This article aims to fill this gap in meta-metaphysical theory by providing a credible justification of the fundamentality of metaphysics in two steps. The first consists in establishing a set of five conditions of fundamentality for the discipline. The second consists in showing that these conditions are satisfied when (...) the object of study of metaphysics is identified with an ontologically neutral object, namely categories, and the task of the discipline is taken to be the determination of the number and identity of the most general categories and the relation of less general categories to the most general ones.
