Ammonius

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)

ABSTRACT: This paper collects the evidence in Ammonius' surviving works for elements of a propositional logic, coming to the conclusion that Ammonius had a theory of hypothetical syllogisms in the tradition of Aristotle and the Peripatetics, with Platonic elements mixed in, and using some Stoic elements, but not a propositional logic in the narrower sense as we find it in Stoic logic.

We have two neoplatonic commentaries on the crucial chapter in Aristotle's De Interpretatione on fatalism.

"Aristotle's On Interpretation, the centrepiece of his logic, examines the relationship between conflicting pairs of statements. The first eight chapters, analysed in this volume, explain what statements are, starting from their basic components - the words - and working up to the character of opposed affirmations and negations." "Ammonius, who in his capacity as Professor at Alexandria from around A.D. 470 taught almost all the great sixth-century commentators, left just this one commentary in his own name, although his lectures on (...) other works of Aristotle have been written up by his pupils, who included Philoponus and Asclepius. His ideas on Aristotle's On Interpretation were derived partly from his own teacher, Proclus, and partly from the great lost commentary of Porphyry. The two most important extant commentaries on On Interpretation, of which this is one, both draw on Porphyry's work, which can be to some extent reconstructed from them."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
