On abstinence from animal food -- Treatise on the Homeric cave of the nymphs -- Auxiliaries to the perception of intelligible natures.

With an introduction to the life of Porphyry and an overview of Neoplatonic thought by David Fideler.

A summary of teachings on the nature of incorporeal principles in the realm of Mind or Spirit.

L'Isagoge est une introduction aux Categories. Porphyre y definit les cinq predicables (genre, espece, difference, propre et accident) et formule ce qui, grace a Boece, deviendra le principal probleme logique et metaphysique du Moyen Age occidental - le probleme des universaux -, ouvrant la querelle qui, jusqu'a la fin du XVe siecle, verra s'affronter realistes et nominalistes. La traduction francaise ici proposee est accompagnee du texte grec original et de la traduction latine de Boece.

A key figure in the history of Aristotelianism, Porphyry (AD 232/3 - c. 305) was born in Tyre and was a student of Longinus' in Athens and of Plotinus' in Rome. In his commentary on the Categories, Porphyry provided an authoritative interpretation of a notoriously controversial work. Commentators on Aristotle had disagreed fundamentally over whether the Categories was a work of logic, concerning simple terms or the simple concepts they represent, or a metaphysical work addressing the classification by (...) genera of simple entities or concepts. Approaching the Categories as the first of Aristotle's works in logic, Porphyry adopted an earlier Peripatetic view of the Categories as being concerned principally with terms or linguistic items, which he calls "predicates." He successfully defended the Categories against Plotinus, arguing that while it seemed to attack orthodox Platonism by denying the separation of forms and the ontological priority of the universal, it was in fact entirely compatible with Platonism. Because of Porphyry's intervention, the Categories came to serve as a basic textbook of logic for subsequent Neoplatonist teaching. His commentary influenced the Arabic tradition, and Boethius drew heavily on it as well. The full text of Porphyry's commentary was lost, but the extant version is available here in Steven K. Strange's new translation. Ancient philosophers, historians of philosophy, classicists, and medievalists will welcome its appearance in English. (shrink)

Ce texte de Porphyre (IIIe siecle) qui presente, en soi, un double interet: d'une part, c'est le seul texte aujourd'hui conserve qui temoigne de l'activite exegetique de ce philosophe neoplatonicien, repute pour avoir commente de nombreux auteurs classiques. Il permet donc d'observer sur le vif la methode de l'exegete et de mesurer en details l'importance de son apport a la recherche interpretative des oeuvres philosophiques anciennes. D'autre part, c'est le premier temoignage conserve des nombreux commentaires consacres, depuis le Ier siecle (...) avant notre ere, a l'explication des Categories d'Aristote. Il permet donc de recolter une information sur les commentaires aujourd'hui perdus qui l'ont precede et dont il offre une maniere de synthese, tout en donnant les moyens de juger jusqu'ou Porphyre a oriente l'interpretation de ce traite celebre pour les siecles suivants, specialement chez les Neoplatoniciens de la fin de l'Antiquite. La nouvelle edition critique du texte grec repose sur la collation de toutes les sources manuscrites connues. Il est donc destine a remplacer la seule edition critique anterieure (qui date du XIXe siecle), en offrant un texte amende en de nombreux passages litigieux, avec un appareil critique continu.

Porphyry's account of the nature of seeds can shed light on some less appreciated details of Neoplatonic psychology, in particular on the interaction between individual souls. The process of producing the seed and the conception of the seed offer a physical instantiation of procession and reversion, activities that are central to Neoplatonic metaphysics. In an act analogous to procession, the seed is produced by the father's nature, and as such it is ontologically inferior to the father's nature. Thus, the (...) seed does not strictly speaking contain a full-fledged vegetative soul. Rather, it acquires its vegetative soul only while it is being actualized by an actual vegetative soul. This actualization takes place primarily at conception, where the seed as it were reverts back and becomes obedient to the mother's nature, but continues through the period of gestation. In this way, Porphyry can account both for maternal resemblance and for ideoplasty. He uses the Stoic language of complete blending to describe the mother's relation to the seed and embryo, and this reveals that he thinks of individuals as having their own unique individual natures (as opposed to sharing in a single universal nature). In the course of developing this theory, Porphyry makes significant revisions to his philosophical predecessors' views in both embryology and botany. He revises Aristotle's verdict on the relative importance of the female in generation as well as Theophrastus' explanation of the biological mechanics of grafting. Although Plotinus nowhere addresses embryology in the same detail as Porphyry does, we can conclude from his remarks on seeds and plants that his own views were similar to those of his student.

This paper presents an analysis of Seneca's 58th letter to Lucilius and Porphyry's Isagoge, which were the origin of the tree diagrams that became popular in philosophy and logic from the early Middle Ages onwards. These diagrams visualise the extent to which a concept can be understood as a category, genus, species or individual and what the method of dihairesis (division) means. The paper explores the dissimilarities between Seneca's and Porphyry's tree structures, scrutinising them through the perspective of (...) modern graph theory. Although traditional trees can be interpreted in a modern way, their terms and definitions defy modern standardisation. These distinctions are not only useful for differentiating between Seneca's and Porphyry's trees, but also for comprehending the evolution of this philosophical tradition. Thus the paper highlights the continued significance of these tree diagrams in analysing concepts and categories in philosophy and structuring objects and information in modern fields such as artificial intelligence, computer science, bioinformatics, graph theory, and many more.

Neoplatonic allegorical interpretation expounds how literary texts present philosophical ideas in an enigmatic and coded form, offering an alternative path to the divine truths. The Neoplatonist Porphyry’s _On the Cave of the Nymphs_ is one of the most significant allegorical interpretation handed down to us from Antiquity. This monograph, exclusively dedicated to the analysis of _On the Cave of Nymphs_, demonstrates that Porphyry interprets Homer’s verse from Odyssey 13.102-112 to convey his philosophical thoughts, particularly on the material world, (...) relationship between soul and body and the salvation of the soul through the doctrines of Plato and Plotinus. The Homeric cave of the nymphs with two gates is a station where the souls descend into genesis and ascend to the intelligible realm. Porphyry associates Odysseus’ long wanderings with the journey of the soul and its salvation from the irrational to rational through escape from all toils of the material world. (shrink)

The Introduction to philosophy written by Porphyry at the end of the second century AD is the most successful work of its kind ever to have been published. It was translated into most respectable languages, and for a millennium and a half every student of philosophy read it as his first text in the subject. Porphyry's aim was modest: he intended to explain the meaning of five terms, 'genus', 'species', 'difference', 'property', and 'accident' - terms which he took (...) to be important to Aristotelian logic and metaphysics, and hence to philosophy in general. Thus in principle the Introduction is simple and elementary. In fact, there are sometimes difficulties and doubts on the surface of the text - and beneath the surface there are frequent depths or profundities. The work raises, directly or indirectly, a number of perennial philosophical questions. In addition, the Introduction became, in Boethius's Latin translation, the point of reference for one of the longest-lasting of philosophical disputes - the dispute over the status of 'universals'.This book contains a new English translation of the Introduction, preceded by a study of the life and works of Porphyry, the purpose and nature of the Introduction, and the history of the text. It is accompanied by a discursive commentary the primary aim of which is to analyse and assess the philosophical theses and arguments which the Introduction puts forward. The twentieth century turned away from Aristotelian logic, and the Introduction lost its position on the syllabus. Barnes does not argue that it should be put back in its old place; but his commentary - the first to be published in English, and the fullest to be published for a century - suggests that there is blood in the old man yet. CLARENDON LATER ANCIENT PHILOSOPHERSGeneral Editors: Jonathan Barnes and A. A. Long This series, which is modelled on the familiar Clarendon Aristotle and Clarendon Plato series, is designed to encourage philosophers and students of philosophy to explore the fertile terrain of later ancient philosophy. The texts range in date from the first century BC to the fifth century AD, and will cover all the parts and all the schools of philosophy. Each volume contains a substantial introduction, an English translation, and a critical commentary on the philosophical claims and arguments of the text. The translations aim primarily at accuracy and fidelity; but they are also readable and accompanied by notes on textual problems that affect the philosophical interpretation. No knowledge of Greek or Latin is assumed. (shrink)

This paper focuses on the summary of one of Porphyry’s arguments against this thesis exposed in Book 2 of Proclus’ _Commentary on the Timaeus_. It argues that Proclus does justice to Porphyry’s views and that the argument points (...) to a classification of powers in Porphyry’s metaphysics that has so far been neglected by scholars.

Porphyry wrote the Contra Christianos during the time of the persecutions, and later several Christian rulers consigned it to the flames. In that work Porphyry included a penetrating critique of Christian allegory. Parts of his argument reappeared in the Protestant Reformers and subsequently in modern biblical research. Scholarship on Porphyry's text often is dominated by the historical problems that beset the fragment. Such problems can be temporarily put aside to carefully study the key terms in Porphyry's (...) argument. The net gain of such an approach is to understand the power of the argument and its structure in a clearer light. (shrink)

Porphyry's Commentary, the only surviving ancient commentary on a technical text, is not merely a study of Ptolemy's Harmonics. It includes virtually free-standing philosophical essays on epistemology, metaphysics, scientific methodology, aspects of the Aristotelian categories and the relations between Aristotle's views and Plato's, and a host of briefer comments on other matters of wide philosophical interest. For musicologists it is widely recognised as a treasury of quotations from earlier treatises, many of them otherwise unknown; but Porphyry's own reflections (...) on musical concepts and his snapshots of contemporary music-making have been undeservedly neglected. This volume presents the first English translation and a revised Greek text of the Commentary, with an introduction and notes designed to assist readers in engaging with this important and intricate work.

Porphyry, the Phoenician polymath, having studied with Plotinus when he was thirty years old, was a well-known Hellenic philosopher, an opponent of Christianity, and was born in Tyre, in the Roman Empire. We know of his anti-Christian ideology and of his defence of traditional Roman religions, by means of a fragment of his Adversus Christianos. This work incurred controversy among early Christians. His Adversus Christianos has been served as a critique of Christianity and a defence of the worship of (...) the traditional gods, so it is inevitable that his texts involved Biblical culture and religious Hellenism. Augustine, in his De Civitate Dei 10. 28, reproves Porphyry for wasting so much time in learning the theurgic arts and rites. This paper does not inquire into whether Porphyry’s philosophical monistic theology is shown in Plotinus’ Enneads, but focuses on his anti-Christian thought through the fragments that we have, particularly Augustine’s De Civitate Dei.

Concerning embryos, Porphyry takes an original view on issues that had been left undecided by his teacher Plotinus and earlier by the doctor Galen. What role is played in the development of the embryo by the souls or the natures of the father, of the mother, of the embryo, or of the whole world? Porphyry's detailed answer, in contrast to Aristotle's, gives a big role to the soul and to the nature of the mother, without, however, abandoning Aristotle's (...) view that the mother supplies no seed. In the fragments of "On What is in Our Power", "Porphyry" discusses Plato's idea that we choose each of our incarnations, and so are responsible for what happens in our lives. (shrink)

Within the third book of Porphyry's On Abstinence from Animal Food, an ethic of community is developed in order to provide the basis of an account of our ethical obligations to animals. I argue that in spite of Porphyry's rejection of this account, it constitutes a coherent and comprehensive nonanthropocentric ethical theory. It conforms with ethical intuitions insofar as it grants that animals are moral subjects, but does not demand impartiality. By appealing to Theophrastus's notion of to oikeion (...) and to the Stoic notion of oikeic6is it provides the theoretical resources for showing why it is often appropriate to favor human beings over other animals.

Porphyry's Against the Christians offers an important example of Hellenic Biblical criticism and a critique of Christianity at the close of Late Antiquity, fl. 300 C.E.

This paper argues that Book 3 of Porphyry’s De abstinentia contains an overlooked argument in favor of vegetarianism for the sake of non-human animals themselves. The argument runs as follows: animals are essentially sentient creatures. Sentience (αἴσθησις) allows them to discern what is good for their survival and what is destructive to them, so that they can pursue the former and avoid the latter. As a result, animals (human and non-human) have preferences, desires, and hopes. Having purposeful strivings that (...) can be promoted or frustrated makes them recipients of justice and injustice. This means, for Porphyry, that animals, unlike plants, can be wronged since they are creatures that discern, and purposefully pursue, what is good or bad for them. This reading stands against interpretations that argue that Porphyry advocates vegetarianism only for our benefit, and not for the animals’ own sake. (shrink)

Scholars working in the field of Graeco-Arabic Neoplatonism often discuss the role Porphyry, the editor of Plotinus, must be credited with in the formation of the Arabic Plotinian corpus. A note in this corpus apparently suggests that Porphyry provided a commentary to the so-called Theology of Aristotle, i.e., parts of some treatises of Enneads IV-VI. Consequently, Porphyry has been considered as responsible for the doctrinal shifts which affect the Arabic Plotinian paraphrase with respect to the original text. (...) This article aims at submitting this hypothesis to trial on a specific doctrinal point where Porphyry parts company with Plotinus: the relationship between the Demiurgic Intellect and World Soul. The ancient doxographical sources testify that Porphyry, in his conviction to be in agreement with Plotinus, in fact parted company with him in so far as he merged the World Soul into the Demiurgic Intellect, while Plotinus always kept them apart. There are in the Enneads some baffling passages where the role of Intellect as the Demiurge of the sensible world is not clearly distinguishable from the role of World Soul. Notwithstanding that, these passages in the Arabic paraphrase do not bear any trace of the characteristically Porphyrian merging of World Soul into Intellect.

This paper studies Sentence 16 of Porphyry’s Pathways to the Intelligible. It is argued that it should be understood against the background of Plotinus’ discussions of the similes of the waxen block and the aviary from Plato’s Theaetetus. The first part of the paper concentrates on Plotinus’ reception of these similes. In the second part of the paper Plotinus’ discussions of the two similes are used to shed light on Sentence 16, in particular on the term προχείρισις. Furthermore it (...) is argued that Porphyry does not reject Plotinus’ claim that, pace Aristotle, intellection does not require imaging. (shrink)

Although recent scholarship has begun to clarify Porphyry’s position on the first principle in its distinction from that of Plotinus we must be careful not to gloss over the crucial ramifications of Porphyry’s developments. The Plotinian One is beyond Being, and thus beyond all relation and difference. In his attempt to understand how such a principle can be productive of all else that follows from it, Porphyry considers the Plotinian One in both its transcendent and creative aspects, (...) introducing the notions of difference and self-relation within the One itself. Porphyry’s modifications of Plotinus’s doctrine, however, result in a first principle having a character utterly distinct from what Plotinus envisioned, and from what I believe Plotinus would have accepted. Because Porphyry’s first principle is relational, it loses its decisive Plotinian character as absolutely transcendent. This distinction between the first principles of Porphyry and Plotinus has important ramifications for each of their philosophical itineraria, and further strengthens the status of Plotinus within the Neoplatonic tradition. Plotinus is a unique thinker within the Neoplatonic tradition, and we must be careful not to equate Neoplatonism with Plotinus, when in fact, it is Plotinus who against both his own predecessors and successors often stands alone.

Describes a Neoplatonic hierarchy of the cardinal virtues extending to immaterial beings, and compares its appropriation by Bonaventure and Aquinas.

In Book 3 of 'On Abstinence from Animal Food', Porphyry is traditionally taken to be arguing in favour of the belief that animals are rational. However, elsewhere in his corpus, he endorses the opposite view, declaring that man differs from other mortal animals because he is rational and they are irrational. Jonathan Barnes offers a way of understanding Porphyry’s logical theory which is intended to make it consistent with the traditional interpretation of 'On Abstinence'. He suggests that the (...) same predicate can be related to different subjects in different ways. Porphyry’s claim that man differs from other mortal animals with respect to the predicate ‘rational’, is best understood to mean that whereas ‘rational’ is specifically predicated of man, it is non-specifically predicated of animals. This explains how they differ from man with respect to this predicate, without failing to be rational. This paper argues that there are reasons for rejecting Barnes’ interpretation. Barnes must maintain, for example, that animals possess the apparently incompatible properties of being specifically irrational and non-specifically rational simultaneously. Since Barnes fails to resolve the conflict, Porphyry’s claims that animals are irrational in his logical works pose a significant problem for the traditional interpretation of 'On Abstinence'.

At In Platonis Timaeum Commentarii II, 1.393.31–394.5 Diehl, Proclus follows Porphyry's inferences against the theory of Atticus, focussing more precisely on the fact that the latter's account of the principles does not correspond to the views expounded by Plato himself. In Diehl's text, based on a limited selection of primary manuscript-witnesses, the introductory phrase to this criticism contains a reference to the maker, which cannot easily be explained within the context. On the basis of a new examination of the (...) manuscript tradition, and of the context of the passage, we will present a new conjecture that allows one to avoid the problems involved in Diehl's reading of the text.

Beginning from Plato, there exists a philosophical tradition, which interprets philosophy as preparation for death. However, for Plato the death of a philosopher does not necessarily imply death in its ordinary meaning, but rather a spiritual way of life maximally free from corporeal affections. This kind of relationship between philosophy and death was intensively discussed in late antique philosophy, Patristics, medieval Byzantine philosophy, and also in medieval Georgian literature. Based on Plato’s and Plotinus’ philosophy, Porphyry presented definitions of three (...) kinds of death in his Sententiae : ‘death’ of a philosopher, natural death, ‘death’ of a soul. The aim of this paper is to provide a philosophical analysis of three concepts of death in the post-Porphyrian tradition, mainly in Byzantine and Georgian texts. The paper is based on the analysis of the above mentioned issues in the texts of Porphyry, Macrobius, Michael Psellos, as well as in the old Georgian versions of the works of Ammonios Hermiae, John of Damascus and John Sinaites. We also take into consideration the views on the relation between philosophy and death in the thought of the philosophers of Humanism and Renaissance, such as Georgios Gemistos Plethon, Marsilio Ficino, Giovanni Pico della Mirandola, and Michel de Montaigne, whether or not and to what extent their views on the relation between philosophy and death are different from the theories of ancient and medieval Platonists.

Porphyry, a native of Phoenicia educated in Athens and Rome during the third century AD, was one of the most important Platonic philosophers of his age. In this book, Professor Johnson rejects the prevailing modern approach to his thought, which has posited an early stage dominated by 'Oriental' superstition and irrationality followed by a second rationalizing or Hellenizing phase consequent upon his move west and exposure to Neoplatonism. Based on a careful treatment of all the relevant remains of (...) class='Hi'>Porphyry's originally vast corpus, he argues for a complex unity of thought in terms of philosophical translation. The book explores this philosopher's critical engagement with the processes of Hellenism in late antiquity. It provides the first comprehensive examination of all the strands of Porphyry's thought that lie at the intersection of religion, theology, ethnicity and culture. (shrink)

This article sheds new light on Themistius’ argument in what is philosophically the most original section of his extant work, namely On Aristotle's On the Soul 100.16–109.3: here, Themistius offers a systematic interpretation of Aristotle's ‘agent’ intellect and its ‘potential’ and ‘passive’ counterparts. A solution to two textual difficulties at 101.36–102.2 is proposed, supported by the Arabic translation. This allows us to see that Themistius engages at length with a Platonizing reading of the enigmatic final lines of De anima III.5, (...) where Aristotle explains ‘why we do not remember’. This Platonizing reading can be safely identified with the one developed in a fragmentary text extant only in Arabic under the title Porphyry's treatise On the soul. While Themistius rejects this reading, he turns out to be heavily influenced by the author's interpretation of the ‘agent’, ‘potential’ and ‘passive’ intellect. These findings offer us a new glimpse into Themistius’ philosophical programme: he is searching for an alternative to both the austere Aristotelianism of Alexander of Aphrodisias and the all too Platonizing reading of Aristotle adopted by thinkers such as Porphyry.
