Aristotelian Commentators, Misc

Commentaries in late antiquity were the predominant form of scholarly engagement with ancient, authoritative texts. Not only in Greek, but in Latin no less, ancient commentaries were an integral part of reading and understanding literature and philosophy (and theology, as part and parcel of philosophy at that time). I shall deal with commentaries (as self-standing works, different from glosses) on poetic, rhetorical, philosophical, and religious texts in Latin late antiquity, both ‘pagan’ and Christian. Grammatical and rhetorical education played a remarkable (...) role in their preparation, and questions of adaptation and of the reuse of earlier material, especially Greek models, will also come into play.

This article expands our knowledge of the historical-philosophical process by which the dominant metaphysical account of the Christian God became ascendant. It demonstrates that Marius Victorinus proposed a peculiar model of ‘consubstantiality’ that utilised a notion of ‘existence’ indebted to the Aristotelian concept of ‘prime matter’. Victorinus employed this to argue that God is a unity composed of Father and Son. The article critically evaluates this model. It then argues that Augustine noticed one of the model's philosophical liabilities but did (...) not publicly name Victorinus when he rejected it in De Trinitate, thereby exemplifying the practice of private ‘rebuke’ (ἐλέγχɛιν).

Around the middle of XVI th century, in the Florence of Grand Duke Cosimo I de’ Medici, Bernardo Segni (Firenze, 1504–1558) translated and commented some Aristotelian works in the Florentine vernacular. His works represents a very important innovation in the panorama of Italian Aristotelianism, because they are the product of circles outside the university world and are the first attempt to translate in Italian the works of the great Greek philosopher. In this paper, I’ll examine some aspects of his works, (...) in particular of his translation of Nicomachean Ethics. (shrink)

In De partibus animalium A1, Aristotle presents —in a darker than usual way— decisive details of the methodology he devised for his science of nature. His indications seem to point the path along which Aristotelian biology should travel. However, numerous textual and systematic difficulties have given rise to a number of conflicting interpretations, in the context of a vigorous stream of philosophical research and debate since the last third of the last century. In this stream of studies, Michael of Ephesus’s (...) commentary on PA and his views on the subject remain relatively ignored. A complex multiplicity of factors seems to support the lack of sufficient consensus among leading contemporary specialists to explicitly consider those contributions. The purpose of this paper is to examine several of these factors and, based on the evidence provided by little explored aspects of Michael’s texts, to offer arguments in favor of that consensus against a number of alternatives. I shall argue that the contributions of this late commentator deserve to be considered —mutatis mutandis— as seriously as it is done with the main ancient Greek commentaries; in particular, in the philosophical studies of those who are currently interested in that methodology or are engaged in Aristotelian biology.

This is the first collected volume dedicated to Olympiodorus of Alexandria, the last pagan Platonic philosopher at the end of antiquity.

This is the only commentary on Aristotle's theological work, Metaphysics, Book 12, to survive from the first six centuries CE – the heyday of ancient Greek commentary on Aristotle. Though the Greek text itself is lost, a full English translation is presented here for the first time, based on Arabic versions of the Greek and a Hebrew version of the Arabic. -/- In his commentary Themistius offers an extensive re-working of Aristotle, confirming that the first principle of the universe is (...) indeed Aristotle's God as intellect, not the intelligibles thought by God. The identity of intellect with intelligibles had been omitted by Aristotle in Metaphysics 12, but is suggested in his Physics 3.3 and On the Soul 3, and later by Plotinus. -/- Laid out here in an accessible translation and accompanied by extensive commentary notes, introduction and indexes, the work will be of interest for students and scholars of Neoplatonist philosophy, ancient metaphysics, and textual transmission.

This paper traces the reception of the Aristotelian definition of time from its earliest to its most authoritative interpretations, and describes how their readings pave the way for a sophisticated amalgamation of divergent Aristotelian and Platonic elements in the temporal theory of Avicenna. The focus of attention lies on specific perceptions of the relation between time and motion, more precisely on the contrary descriptions of time as the measure of motion and motion as the measure of time. The latter leads (...) to a conception of time as a universal self-subsisting substance beyond all measure, and the former to an understanding of time as an accident providing all motion with its particular measure. It is the antagonism between these two conceptions, both inherent in the Arabic term miqdār at the heart of Avicenna’s definition of time, which arguably informs the Latin tradition and thereby also shapes the early modern contrast between objective and subjective theories of time.

Celebrated as the equal to the great philosophers of old, namely Plato and Aristotle, whom – as Cassiodorus put it – he taught to speak Latin better than they spoke Greek, Boethius aspired to fully emancipate Roman culture from its Greek models through translations and exegesis so faithful they would leave nothing more to be desired from the original. The essay focuses on Boethius philhellenism, without complexes insofar as it had little to do either with the mixed feelings of his (...) Roman predecessors or with the plundering agenda of his Christian contemporaries. Special attention is paid to the close relationship Boethius established between word for word translations and multi-layered commentaries which he thought of and – albeit partially – carried out as part of the same scholarly endeavour. Devoid of literary pretentions as well as free from aspirations to autonomy, Boethius literal rendering and scrupulous interpretation were meant to be completely self-sufficient. Together they stand out as both the most innovative and the most conservative features of his ambitious cultural project. -/- Célébré comme l’égal des grands philosophes du passé, auxquels il aurait appris à parler Latin mieux qu’ils ne parlaient Grec, Boèce a caressé le rêve d’une émancipation radicale de la culture romaine vis-à-vis des modèles grecs qu’il se proposait de traduire et interpréter assez fidèlement pour que la comparaison avec les sources ne soit plus nécessaire. De son effort de livrer un Aristote et un Platon latins à la hauteur des originaux grecs, nous étudions l’étroite solidarité qui relie la traduction mot-à-mot des textes grecs et la restitution scrupuleuse de leur sens. Cette double tâche, que Boèce a conçue et menée d’un seul tenant, nous est dès lors apparue comme le reflet d’un philhellénisme sans complexes, tout aussi éloigné des sentiments ambivalents que nourrissaient vis-à-vis des hellènes ses devanciers romains que des efforts visant à domestiquer l’héritage classique auxquels se livraient certains de ses contemporains de même confession que lui. Affranchis de tout rêve d’autonomie, les traductions et les commentaires de Boèce se conçoivent comme parfaitement autosuffisants. Ensemble ils constituent ce qu’il y a à la fois de franchement novateur et de profondément conservateur dans son projet de faire parler Latin les sources grecques. (shrink)

One of the main issues that dominates Neoplatonism in late antique philosophy of the 3rd–6th centuries A.D. is the nature of the first principle, called the ‘One’. From Plotinus onward, the principle is characterized as the cause of all things, since it produces the plurality of intelligible Forms, which in turn constitute the world’s rational and material structure. Given this, the tension that faces Neoplatonists is that the One, as the first cause, must transcend all things that are characterized by (...) plurality—yet because it causes plurality, the One must anticipate plurality within itself. This becomes the main mo- tivation for this study’s focus on two late Neoplatonists, Proclus (5th cent. A.D.) and Damascius (late 5th–early 6th cent. A.D.): both attempt to address this tension in two rather different ways. Proclus’ attempted solution is to posit intermediate principles (the ‘henads’) that mirror the One’s nature, as ‘one’, but directly cause plurality. This makes the One only a cause of unity, while its production of plurality is mediated by the henads that it produces. Damascius, while appropriating Proclus’ framework, thinks that this is not enough: if the One is posed as a cause of all things, it must be directly related to plurality, even if its causality is mediated through the henads. Damascius then splits Proclus’ One into two entities: (1) the Ineffable as the first ‘principle’, which is absolutely transcendent and has no causal relation; and (2) the One as the first ‘cause’ of all things, which is only relatively transcendent under the Ineffable. -/- Previous studies that compare Proclus and Damascius tend to focus either on the Ineffable or a skeptical shift in epistemology, but little work has been done on the causal framework which underlies both figures’ positions. Thus, this study proposes to focus on the causal frameworks behind each figure: why and how does Proclus propose to assert that the One is a cause, at the same time that it transcends its final effect? And what leads Damascius to propose a notion of the One’s causality that no longer makes it transcendent in the way that a higher principle, like the Ineffable, is? The present work will answer these questions in two parts. In the first, Proclus’ and Damascius’ notions of causality will be examined, insofar as they apply to all levels of being. In the second part, the One’s causality will be examined for both figures: for Proclus, the One’s causality in itself and the causality of its intermediate principles; for Damascius, the One’s causality, and how the Ineffable is needed to explain the One. The outcome of this study will show that Proclus’ framework results in an inner tension that Damascius is responding to with his notion of the One. While Damascius’ own solution implies its own tension, he at least solves a difficulty in Proclus—and in so doing, partially returns to a notion of the One much like Iamblichus’ and Plotinus’ One.

In Augustinus Niphus’ commentary on Aristotle’s Physics some marginal annotations can be considered an aide-mémoire for teachers commenting Aristotle’s text. In these annotations titles of questions concerning problems raised by Aristotle’s discussion on motion are recorded together with some medieval and renaissance comments. The analysis of these annotations is limited to the pages of the discussion on vacuum.

Aristotle, in Chapter 7 of his Categories, classifies habits and dispositions, as well as knowledge, among relatives. However, in Chapter 8 of the Categories, he affirms that habits, including knowledge, and dispositions, including unstable knowledge, are qualities. Thus, habits and dispositions in general, and knowledge in particular, seem to be subject to a ‘dual categorization’. At the end of Chapter 8 of the treatise, the issue of the dual categorization is explicitly raised. How can one and the same thing be (...) a quality and a relative? Aristotle gives two distinct solutions to this problem. Both have been criticized by some modern commentators : these solutions would amount to a rejection of the basic principles of the categorial system and, as such, to a sort of philosophical suicide. However, Aristotle’s early commentators, notably the Greek Neoplatonists and Boethius, made attempts to render both solutions plausible and compatible with the rest of the doctrine. Their attempts are not only of exegetical interest, they also contain some significant philosophical analyses concerning the categories. In what follows, I will present the abovementioned problem of dual categorization in Aristotle and the two solutions offered to it in Categories, 8, 11a20-38. I will then turn to the early reception of this text, and focus on the way the Greek Neoplatonists and Boethius tried to make Aristotle’s solutions more plausible. Throughout, I will try to establish in what sense habits and dispositions in general, and knowledge in particular, are relative. I will conclude with some remarks on the later reception of Categories, 8, 11a20-38 and on the problem of the ontological status of mental acts and states. (shrink)

Starting with Aristotle and moving on to Darwin, Marco Solinas outlines the basic steps from the birth, establishment and later rebirth of the traditional view of living beings, and its overturning by evolutionary revolution. The classic framework devised by Aristotle was still dominant in the 17th Century world of Galileo, Harvey and Ray, and remained hegemonic until the time of Lamarck and Cuvier in the 19th Century. Darwin's breakthrough thus takes on the dimensions of an abandonment of the traditional finalistic (...) theory. It was a transition exemplified in the morphological analysis of useless parts, such as the sightless eyes of moles, already discussed by Aristotle, which Darwin used as a crowbar to unhinge the systematic recourse to final causes. With many excerpts, a chronological sequence and an analytical approach, this book follows the course of the two conceptions that have shaped the destiny of life sciences in western culture.

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)

This paper investigates Péter Pázmány’s theory of mixtures from his exegesis of Meteorologica IV, in the context of sixteenth-century scholarship on Aristotle’s Meteorologica. It aims to contribute to a discussion of Anneliese Maier’s thesis concerning the incompatibility between hylomorphism and the theory of elements in the Aristotelian tradition. It presents two problems: the placement of Meteorologica IV in the Jesuit cursus on physics and the conceptualization of putrefaction as a type of substantial mutation. Through an analysis of these issues, it (...) shows how sixteenth-century exegesis imposes the hylomorphic thesis onto the subject matter of meteorology and how the hylomorphic theory of substantial change can be adapted in order to accommodate the theory of elements. The case being made is that Meteorologica is a privileged place where hylomorphism and the theory of elements meet and that the late Aristotelian theory of mixtures sought to accommodate both theories of material substance.

Péter Pázmány taught philosophy at the Jesuit university of Graz, end of 16th century. This analyzes his interpretation of Aristotelian psychology.

Augustine on select metaphysical topics: hylomorphism vs. dualism, theories of God, angels.

Descartes set for himself the ambitious program of accounting for the functions of the Aristotelian vegetative and sensitive souls without invoking souls or the faculties or powers of souls in his explanations. He rejects the notion that the soul is hylomorphically present in the organs of the body so as to carry out vital and sensory functions. Rather, the body’s organs operate in a purely mechanical fashion. That is what is involved in “mechanizing” these phenomena. The role of the soul (...) is restricted to properly mental functions: to the conscious aspects of sensations and other mental operations; to intellectual acts; and to acts of volition. In effect, soul becomes mind. In order to understand the extent of Descartes’ ambition, this chapter first considers more fully the functions attributed to the soul or to the vital faculties in the Aristotelian and Galenic traditions, and especially the functions of the sensitive soul or power. It draws attention to the cognitive aspects of these functions, beyond the mere operation of the external senses. Then it turns to Descartes’ mechanistic explanations for these cognitive functions. Finally, it situates Descartes’ new mechanistic psychology within the larger context of his novel anthropology, or theory of the human being. (shrink)

The book aims to offer a contribution to the historiographical and conceptual reconfiguration of the evolutionary revolution in the light of the centuries-old tenets of the Aristotelian biological tradition. Darwin’s breakthrough constitutes a thorough overturning of the fixist, essentialist and teleological framework created by Aristotle, a framework still dominant in the 17th Century world of Harvey and Ray, as well as Galileo, and then hegemonic until Linnaeus and Cuvier. This change is exemplified in the morphological analysis of useless parts, such (...) as the sightless eyes of moles, already discussed by Aristotle, and which Darwin used almost like a crowbar to unhinge the systematic recourse to final causes. This is an ancient teleological heritage present in various forms in the concept of natural selection, but by then confined within an eminently historical framework open to randomness. Un contributo alla riconfigurazione storiografica e concettuale della rivoluzione evoluzionistica alla luce della tenuta plurisecolare della tradizione biologica aristotelica. La svolta di Darwin si delinea quale puntuale rovesciamento dell'impianto fissista, essenzialista e teleologico coniato da Aristotele, ancora dominante nel Seicento di Harvey e di Ray, nonostante Galileo, e poi egemone fino a Linneo e Cuvier. Svolta esemplificata dall'analisi morfologica delle parti inutili, come gli occhi ciechi della talpa, tematizzate già da Aristotele, e che Darwin usò quale grimaldello per scardinare il ricorso sistematico alle cause finali. Antica eredità teleologica presente in varie forme nel concetto di selezione naturale, ma ormai calata entro una griglia eminentemente storica e aperta alla casualità. (shrink)

Analyzing the reasons why we fail to grasp genuinely first principles, this book gives a new perspective on how to understand the meaning of the radical aporetism in the treatise on the first principles written by Neoplatonic philosopher Damaskios. Analysant les raisons de nos échecs à dire, connaître et concevoir authentiquement les principes premiers, ce livre offre une compréhension nouvelle du sens et du rôle de l’aporétique radicale du traité des Principes Premiers du néoplatonicien Damaskios.

The search for an agreement between Aristotle’s and Descartes’ philosophy was aimed at making Cartesian physics acceptable in the Dutch universities by showing its consistency with Aristotelian thought. Their agreement is defended by Johannes De Raey in the Clavis philosophiae naturalis (1654), where he interprets the Corpus Aristotelicum from a Cartesian standpoint. Those Aristotelian positions which are inconsistent with Descartes’ are treated as erroneous. The Scholastic positions, moreover, are considered as distant from the true Aristotelian philosophy rediscovered by Descartes.

This book contains the first English translation of Abūl-Walīd Ibn Rushd's (Averroes') so-called Epitome of Aristotle's Metaphysics. The original Arabic text was composed around 1160 as a sort of appendix to a series of compendia of Aristotle's works on natural philosophy by the famous Andalusian philosopher. The two most interesting things about this work are the fact that Averroes restructures here the Aristotelian text according to his own conception of metaphysics, as opposed to his great literal commentary which follows the (...) order of the Metaphysics section by section, and that he constantly revised this work over more than three decades. The present translation is based on a wide range of documents including, apart from the available Arabic editions, a number of medieval Arabic manuscripts not taken into consideration in these editions as well as the Renaissance translation into Latin prepared by Jacob Mantinus. It is accompanied by a commentary dealing with the major philosophical topics, Averroes' sources and problems of the transmission and constitution of the text. In addition, the most important variant readings of the manuscripts are noted in footnotes underneath the translation. (shrink)

The Prior and Posterior Analytics were entitled Ta Analutika by Aristotle himself. But it is not at all clear what Aristotle had in mind in grouping these two works together and in giving them this common title. This question was discussed at length by the ancient Greek commentators on Aristotle. Two main possibilities emerged. The first is that taken by Alexander of Aphrodisias, Ammonius, and Philoponus in his commentary on APr. According to this line of thought, Aristotle has in mind (...) the analysis that shows how a complex arises out of simple entities; both Analytics show us how to subject all lines of syllogistic reasoning (including demonstration) to such analysis. According to the second approach, found in the commentary on APo., 2 attributed to Philoponus, in giving APo., 2 the title 'Analytics' Aristotle has in mind the analysis that reasons from effects to causes. Demonstrations reveal the causes of things, and APo., 2 shows how this is the case. In this paper, the two approaches are compared, and a third approach, which builds on the second, but allows 'Analytics' to have a continuity of sense in its use as a title, is proposed. (shrink)

In Plato’s Parmenides 132a-133b, the widely known Third Man Paradox is stated, which has special interest for the history of logical reasoning. It is important for philosophers because it is often thought to be a devastating argument to Plato’s theory of Forms. Some philosophers have even viewed Aristotle’s theory of predication and the categories as inspired by reflection on it [Owen 1966]. For the historians of logic it is attractive, because of the phenomenon of self-reference that involves. Bocheński denies any (...) possibility of correct logical reasoning before Aristotle. In particular, he flatly declares of Plato that “correct logic we find none in his work” [1951, 15]. In this line, many papers have been written that call attention to the violation of a metalogical principle – the type rules – because of the Third Man Paradox. The problem of interpretation of the paradox raised many discussions, since the 50’s, and the literature devoted to this topic is today enormous. Nevertheless, many points in Plato’s reasoning remain obscure. Hitherto, it is commonly believed that the paradox was simply stated by Plato in his "Parmenides", but not actually solved. Even more, it is believed that it is hardly possible for Plato to have suggested a solution, because he confused the categories of substance and attribute. B. Russell has also argued that Plato violates in his arguments the restrictions imposed on language by the theory of logical types. This view is encouraged by the linguistic difficulties, which Plato has faced in his attempt to formulate an ontology of abstract entities, i.e. that in Greek language abstract and concrete terms are formally indistinguishable [Kneales 1984]. In this paper, we analyse the logical structure of the argument in an attempt to give a systematic consistent reconstruction of the text appealing to methods and concepts of modern logic and semantics. Already in 1954 G. Vlastos had noted in his seminal paper “The ‘Third Man’ Argument in the Parmenides” that “if any progress … is to be made at this juncture it must come from some advance in understanding the logical structure of the Argument”. Accordingly, our analysis is primarily focused on the line of logical reasoning, rather than the metaphysical underpinnings and philosophical implications of the paradox for Plato’s theory of Forms. We divide the Platonic text into three parts, presenting apparent thematic coherence: a) Formulation of the Third Man Paradox (132a-132b). The central issue of this part is a step-like generation of Forms that can continue ad infinitum. b) Discussion of the paradoxical situation (132b-c), by passing to the use of terminology echoing Eleatic philosophy. The concept of “thought” and the underlying semantics of Eleatic origin are central in this passage. c) Solution of the paradox (132d-133a). In our view, this part contains not only a resemblance regress, as most interpretators con-sider, but also the solution of the paradox by the introduction of a sound definition of the concept of “similarity”. We should note that the name ‘Third Man Paradox’ never occurs in Plato, who, strictly speaking, formulates a ‘Third Large Paradox’. The name ‘Third Man Paradox’ appears in the works of Aristotle and the commentators of the Peripatetic tradition. Later commentators have identified Aristotle’s Third Man with Plato’s Third Large Argument. In our paper, we also examine other testimonies about the Third Man Paradox found in the works of commentators in order to illuminate the logical structure of the argument. Although the vocabulary used in these versions is different, they do not affect its logical structure, but rather reveal different understandings by the ancient authors. These testimonies are divided into two main categories: those met in Neo-Platonic authors, notably in Proclus’ "Commentary on Plato’s Parmenides", and the versions of the Third Man Paradox found in texts of the Peripatetic tradition (Eudemus, Aristotle, Alexander). From our discussion, it becomes clear that the approaches to the paradox by the various scholars of antiquity are different, depending also on their participation in the one or the other campus of philosophical thought. We show that the Peripatetic authors are aware of the source of the paradox. However, the first scholar of antiquity who explicitly ascribes a solution to Plato seems to be Proclus. (shrink)

Aspasius' commentary on the "Nicomachean Ethics", of which six books have come down to us, is the oldest surviving Greek commentary on any of Aristotle's works, dating to the middle of the second century AD. It offers precious insight into the thinking and pedagogical methods of the Peripatetic school in the early Roman Empire, and provides illuminating discussions of numerous technical points in Aristotle's treatise, along with valuable excursuses on such topics as the nature of the emotions.

The Commentary on the Categories by Abū l-Farağ ibn aṭ-Ṭayyib is an important representative of the Aristotelian tradition in Arabic culture.

Aquinas puts forward two different, and conflicting, interpretations of Themistius’s account of the intellect. In his earlier interpretation of Themistius, Aquinas understands him to hold the position that both the possible and agent intellect are separate and incorruptible, existing apart from individual human souls but shared in by individual souls in the process of knowing. In De unitate intellectus contra averroistas, however, Aquinas radically departs from this reading, hailing Themistius as a genuine interpreter of the Peripatetic position, while decrying Averroes’s (...) perversion of both Themistius and Aristotle. This paper examines these competing interpretations of Themistius’s account of the intellect in his Commentary on the De anima of Aristotle, focusing on two issues central to its interpretation: (1) the nature of intellect insofar as it is separate, impassive, and unmixed, and (2) whether the productive intellect is one or many.

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 : the works commonly referred to as the Short, Middle, and Long Commentaries.

In this paper I present the text, a translation, and a commentary of a long anonymous scholium to Aristotle’s Analytics which is a Greek parallel to Boethius’ De Hypotheticis Syllogismis, but has so far not been recognized as such. The scholium discusses hypothetical syllogisms of the types modus ponens and modus tollens and hypothetical syllogisms constructed from three conditionals (‘wholly hypothetical syllogisms’). It is Peripatetic, and not Stoic, in its theoretical approach as well as its terminology. There are several elements (...) of early Peripatetic hypothetical syllogistic preserved in it, and there is a large number of close parallels to Boethius’ De Hypotheticis Syllogismis which we find in no other source. It is very likely that there was a Greek source from which both the scholium and large parts of Boethius’ De Hypotheticis Syllogismis are ultimately derived. (shrink)

Although Themistius does not develop a theodicy, his observations on evil are fairly consistent. Both in his paraphrases of Aristotle and in his speeches, he argues that since God is the intelligent and powerful cause of all good things in the universe, evil is due to the στέρησις in matter and to the ἄνοιι of human beings. Despite some (Neo-)Platonic and Stoic influences, Themistius defends a basically Peripatetic world-view, in which evil is minimized.
