In recent years, some controversy has arisen about whether Thomas Aquinas’s commentaries on Aristotle can be read as expressing Aquinas’s own views rather than as simply an interpretation of Aristotle. This article examines the reasons given in favor of the view that the commentaries, in particular the commentary on the Nicomachean Ethics, are merely interpretations of Aristotle. Using Thomas’sscripture commentaries, internal evidence, as well as the history of reception, it is concluded that the Sententia libri ethicorum presents Thomas’s own views and not merely his understanding of Aristotle.

This volume contains a close translation, suitable for students without a knowledge of Greek, of the seventh and eighth books of Aristotle's Metaphysics, together with a thorough and careful philosophical commentary. In these difficult books, which are central to his metaphysical system, Aristotle discusses the nature of perceptible reality. In particular, he discusses which of matter and form might be the basic reality of things, and he frequently contrasts his own view of form with the Platonic view. Several other topics are treated which are of central importance to his metaphysics, such as the notions of essence and definition, the status of universals, and the concept of a unity.

Translation with notes of Ammonius' Commentary on Aristotle's Categories.

Aristotle's account of place in terms of an innermost limit of a containing body was to generate serious discussion and controversy among Aristotle's later commentators, especially when it was applied to the cosmos as a whole. The problem was that since there is nothing outside of the cosmos that could contain it, the cosmos apparently could not have a place according to Aristotle's definition; however, if the cosmos does not have a place, then it is not clear that it could move, but it was thought to move, namely, in its daily revolution, which was viewed as a kind of natural locomotion and so required the cosmos to have a place. The study briefly outlines Aristotle's account of place and then considers its fate, particularly with respect to the cosmos and its motion, at the hands of later commentators. To this end, it begins with Theophrastus' puzzles concerning Aristotle's account of place, and how later Greek commentators, such as Alexander of Aphrodisias, Themistius and others, attempted to address these problems in what can only be described as ad hoc ways. It then considers Philoponus' exploitation of these problems as a means to replace Aristotle's account of place with his own account of place understood in terms of extension. The study concludes with the Arabic Neoplatonizing Aristotelian Avicenna and his novel introduction of a new category of motion, namely, motion in the category of position. Briefly, Avicenna denies that the cosmos has a place, and so claims that it moves not with respect to place, but with respect to position.

The first major work in the history of philosophy to bear the title "Metaphysics" was the treatise by Aristotle that we have come to know by that name. But Aristotle himself did not use that title or even describe his field of study as 'metaphysics'; the name was evidently coined by the first century C.E. editor who assembled the treatise we know as Aristotle's Metaphysics out of various smaller selections of Aristotle's works. The title 'metaphysics' -- literally, 'after the Physics' -- very likely indicated the place the topics discussed therein were intended to occupy in the philosophical curriculum. They were to be studied after the treatises dealing with nature (ta phusika). In this entry, we discuss the ideas that are developed in Aristotle's treatise.

Everson presents a comprehensive new study of Aristotle's account of perception and related mental capacities. Recent debate about Aristotle's theory of mind has focused on this account, which is Aristotle's most sustained and detailed attempt to describe and explain the behavior of living things. Everson places this account in the context of Aristotle's natural science as a whole, showing how Aristotle applies the explanatory tools he developed in other works to the study of perceptual cognition.

Averroës, the greatest Aristotelian of the Islamic philosophical tradition, composed some thirty-eight commentaries on the "First Teacher's" corpus, including three separate treatments of De Anima ("On the Soul"): the works commonly referred to as the Short, Middle, and Long Commentaries. The Middle Commentary--actually Averroës's last writing on the text-remains one of his most refined and politically discreet treatments of Aristotle, offering modern readers Averroës's final statement on the material intellect and conjunction as well as an accessible historical window on Aristotle's work as it was interpreted and transmitted in the medieval period.

The first sentence of NE I.2 has roughly the form: "If A [there is a universal end] and B (because, if not-B, then C), then D [this end will be the best good]". According to some commentators, Aristotle uses B to infer A; but then the sentence is fallacious. According to other commentators, Aristotle does not use B (until later on); but then the sentence is bizarre. Contrary to both sets of commentators (but following Wedin 1981), I suggest that Aristotle uses B together with A to infer validly that there is a non-instrumental -- and thus unique -- universal end (hence D). On this interpretation the above two problems disappear, but a subtler problem emerges: not-B does not entail C.

: Aristotle's metaphysics has stimulated intense renewed debate in the past twenty years. Much of the discussion has focused on Metaphysics Z, Aristotle's fascinating and difficult investigation of substance (ousia), and to a lesser extent on H and Θ. The place of the central books within the larger project of First Philosophy in the Metaphysics has engaged scholars since antiquity, and that relationship has also been reexamined. In addition, scholars have been exploring the Metaphysics from various broader perspectives—first, in relation to Aristotle's natural philosophy, his physics, biology, and psychology, and to the Organon, his so-called "logical" works, which include the Categories, Topics, and Posterior Analytics; and second, in relation to the broader philosophical tradition, both Plato before him and the ancient commentary tradition in late antiquity.
