"An account of the central tradition in the history of philosophy, Platonism, along with the class of philosophical positions collectively known as Naturalism and the 'anti-Platonism' of Naturalism both in antiquity and in contemporary philosophy"--.

'Middle' Platonism has some claim to be the single most influential philosophical movement of the last two thousand years, as the common background to 'Neoplatonism' and the early development of Christian theology. This book breaks with the tradition of considering it primarily in terms of its sources, instead putting its contemporary philosophical engagements front and centre to reconstruct its philosophical motivations and activity across the full range of its interests. The volume explores the ideas at the heart of Platonist philosophy (...) in this period and includes a comprehensive selection of primary sources, a significant number of which appear in English translation for the first time, along with dedicated guides to the questions that have been, and might be, asked about the movement. The result is a tool intended to help bring the study of Middle Platonism into mainstream discussions of ancient philosophy. (shrink)

Byzantine intellectuals not only had direct access to Neoplatonic sources in the original language but also, at times, showed a particular interest in them. During the Early Byzantine period Platonism significantly contributed to the development of Christian doctrines and, paradoxically, remained a rival world view that was perceived by many Christian thinkers as a serious threat to their own intellectual identity. This problematic relationship was to become even more complex during the following centuries. Byzantine authors made numerous attempts to harmonize (...) Neoplatonic doctrines with Christianity as well as to criticize, refute and even condemn them. The papers assembled in this volume discuss a number of specific questions and concerns that drew the interest of Byzantine scholars in different periods towards Neoplatonic sources in an attempt to identify and explore the central issues in the reception of Neoplatonic texts during the Byzantine era. This is the first volume of the sub-series "Byzantinisches Archiv - Series Philosophica", which will be dedicated to the rapidly growing field of research in Byzantine philosophical texts. (shrink)

_ Source: _Volume 11, Issue 1, pp 46 - 70 In this article, I analyze the idea of “stepping into the void”, which can be traced in the thinking of both Proclus and Damascius, but which sets their perspectives apart. Thus, I show how Proclus warns us that to speak about the absolute principle, taking it as an object of thought, is a negative “stepping into the void” that should be avoided. On the contrary, I show that Damascius starts from (...) this warning and tries to prove that the only adequate manner in which we can trace the absolute principle and approach it is precisely through “stepping into the void,” yet, this time, in a positive sense, as a constant attempt to understand that the principle is an absolute void which reverses our discourse.

Consider a circle and a pair of its semicircles. Which is prior, the whole or its parts? Are the semicircles dependent abstractions from their whole, or is the circle a derivative construction from its parts? Now in place of the circle consider the entire cosmos (the ultimate concrete whole), and in place of the pair of semicircles consider the myriad particles (the ultimate concrete parts). Which if either is ultimately prior, the one ultimate whole or its many ultimate parts?

Grounding is often glossed as metaphysical causation, yet no current theory of grounding looks remotely like a plausible treatment of causation. I propose to take the analogy between grounding and causation seriously, by providing an account of grounding in the image of causation, on the template of structural equation models for causation.

In his Life of Plotinus , Porphyry makes reference to certain gnostic ‘revelations’ under the names of ‘Zoroaster and Zostrianos and Nicotheus and Allogenes and Messos and many others of this kind’ which were circulated in Plotinus' school and refuted by Plotinus and his students, including Porphyry himself. Porphyry claims to have made ‘several refutations against the book of Zoroaster’ while Amelius apparently wrote some ‘forty volumes against the book of Zostrianos’. The surprising discovery of Coptic gnostic texts in the (...) Nag Hammadi Library under the specific names of Allogenes and Zostrianos and the close relation of these texts to The Three Steles of Seth and Marsanes has led to the general consensus that we now possess some of the actual texts mentioned by Porphyry.

This study proposes that Neoplatonism, while not a modern philosophy, is philosophy in the modern sense. Lloyd analyzes the key structures that underlie the dogmas of the Neoplatonic world picture, including the concept of emanation, the return of the soul to the One, the place of mystical knowledge, epistemology, and Porphyry's theory of predication, and shows that they rest on original but intelligible concepts and arguments.

I will defend two claims. First, Schaffer's priority monism is in tension with many research programs in quantum gravity. Second, priority monism can be modified into a view more amenable to this physics. The first claim is grounded in the fact that promising approaches to quantum gravity such as loop quantum gravity or string theory deny the fundamental reality of spacetime. Since fundamental spacetime plays an important role in Schaffer's priority monism by being identified with the fundamental structure, namely the (...) cosmos, the disappearance of spacetime in these views might undermine classical priority monism. My second claim is that priority monism can avoid this issue with two moves: first, in dropping one of its core assumptions, namely that the fundamental structure is spatio-temporal, second, by identifying the connection between the non-spatio-temporal structure and the derivative spatio-temporal structure with mereological composition.

This is the first book to provide an account of the influence of Proclus, a member of the Athenian Neoplatonic School, during more than one thousand years of European history. Proclus was the most important philosopher of late antiquity, a dominant voice in Byzantine thought, the second most influential Greek philosopher in the later western Middle Ages, and a major figure in the revival of Greek philosophy in the Renaissance. Proclus was also intensively studied in the Islamic world of the (...) Middle Ages and was a major influence on the thought of medieval Georgia. The volume begins with a substantial essay by the editor summarizing the entire history of Proclus' reception. This is followed by the essays of more than a dozen of the world's leading authorities in the various specific areas covered. (shrink)

What is the relation between a whole and its parts? The metaphysics of structure and composition is much discussed in modern philosophy; now Verity Harte provides the first sustained examination of Plato's rich but neglected discussion of the topic, and shows how it can illuminate current debates. This book is an invaluable resource both for scholars of Plato and for modern metaphysicians.

R. J. Hankinson traces the history of ancient Greek thinking about causation and explanation, from its earliest beginnings through more than a thousand years to the middle of the first millennium of the Christian era. He examines ways in which the Ancient Greeks dealt with questions about how and why things happen as and when they do, about the basic constitution and structure of things, about function and purpose, laws of nature, chance, coincidence, and responsibility.

This study examines a number of different answers to the question: wheredoes Avicenna demonstrate the existence of God within the Metaphysics of the Healing? Many interpreters have contended that there is an argument for God’s existence in Metaphysics of the Healing I.6–7. In this study I show that such views are incorrect and that the only argument for God’s existence in the Metaphysics of the Healing is found in VIII.1–3. My own interpretation relies upon a careful consideration of the scientific (...) order and first principles of the Metaphysics of the Healing, paying attention to Avicenna’s own explicit statements concerning the goals andintentions of different books and chapters, and a close analysis of the structure ofthe different arguments found in the relevant texts of the Metaphysics of the Healing. I conclude that Avicenna’s explicit goal in I.6–7 is to establish the properties that belong to necessary existence and possible existence, which consists, not in ademonstration of God’s existence, but in a dialectical treatment of the first principlesof metaphysics.

I use Plotinus to present absolute divine simplicity as the consequence of principles about metaphysical and explanatory priority to which most theists are already committed. I employ Phil Corkum’s account of ontological independence as independent status to present a new interpretation of Plotinus on the dependence of everything on the One. On this reading, if something else (whether an internal part or something external) makes you what you are, then you are ontologically dependent on it. I show that this account (...) supports Plotinus’s claim that any entity with parts cannot be fully independent. In particular, I lay out Plotinus’s case for thinking that even a divine self-understanding intellect cannot be fully independent. I then argue that a weaker version of simplicity is not enough for the theist since priority monism meets the conditions of a moderate version of ontological independence just as well as a transcendent but complex ultimate being.

The first part of this article focuses on Plotinus’ account of demiurgic causation in treatise VI, 7 [38]. Plotinus’ position is based on two assumptions : 1) the sensible cosmos is rationally ordered and its order depends on an intelligible prior cause ; 2) this order does not reflect any rational design on the part of the cause, since the cause has no reasoning or calculation in it. This view is spelled out against the background of Plotinus’ gradualist metaphysics and (...) with respect to Plotinus’ philosophical sources. The second part of the article focuses on Porphyry, on the anonymous commentary on Plato’s Parmenides and on Iamblichus. Unlike Plotinus, Porphyry has no hesitation in employing concepts drawn from Aristotle’s logic as a resource for expressing his metaphysical theories. This approach can interestingly be set in parallel with that of the anonymous commentary to Plato’s Parmenides assigned to Porphyry by Pierre Hadot. A hitherto unnoticed parallel between these lines and Porphyry’s view on the divine hierarchy criticised in Iamblichus’ Response to Porphyry provides a new argument in support of Porphyry’s authorship of the Parmenides commentary.

Avicenna's analysis of the definition of substance and accident repeatedly emphasizes two points: one and the same essence cannot be substance in one instance and accident in another; whetherxis extrinsic or intrinsic for an underlying subject,ydoes not tell us anything as to whetherxis substance or not. Both points are development in an argument against certain unnamed people who claimed the opposite. In this article I will show that Avicenna's opponents are to be identified with the mainstream Baghdad Peripatetic School which (...) based itself on the Late Antique rule that “parts of substances are substances”. As for Avicenna's own position, it was developed on the basis of the heterodox position of Yaḥyā b. ʿAdī, who anticipated Avicenna's first point. This is a further piece of evidence for something that has only recently begun to be appreciated: the influence of Ibn ʿAdī on Avicenna.RésuméL’analyse d’Avicenne portant sur les définitions de la substance et de l’accident met en exergue les deux propositions suivantes: 1) la même essence ne peut être à la fois une substance dans un cas et un accident dans un autre; 2) le fait quexsoit extrinsèque ou intrinsèque à unysous-jacent ne nous permet pas de conclure quexest une substance. Ces deux propositions sont articulées dans un débat avec d’autres personnes ayant un point de vue opposé dont on ne connaît pas l’identité. Dans cet article, nous verrons que ces adversaires font partie de l’école péripatétique de Bagdad, qui elle-même s’appuie sur une proposition datant de l’Antiquité tardive et selon laquelle les parties de substances sont elles-mêmes des substances. La position d’Avicenne fut développée à partir de celle de Yaḥyā b. ʿAdī. Cet article apporte ainsi un argument nouveau qui met en évidence l’influence, remarquée seulement depuis peu, d’Ibn ʿAdī sur Avicenne. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Scepticism in the Sixth Century? Damascius’ Doubts and Solutions Concerning First PrinciplesSara RappeThe Doubts and Solutions Concerning First Principles, an aporetic work of the sixth century Neoplatonist Damascius, is distinguished above all by its dialectical subtlety. Although the Doubts and Solutions belongs to the commentary tradition on Plato’s Parmenides, its structure and method make it in many ways unique among such exegetical works. The treatise positions itself, at least (...) in part, as a response to Proclus’ metaphysical system. Thus the first principles alluded to in its title refer to a metaphysical structure consisting of five central elements, the Ineffable, the One, and the Noetic Triad, which Damascius both adumbrates in opposition to Proclus1 as well as subjects to his own, internal critique. In this article, I will be asking whether or not Damascius’ critique of Neoplatonic metaphysics is informed or inspired by ancient Scepticism. No doubt this question catches the reader off guard: if the last exponent of ancient Scepticism is Sextus Empiricus, how could this sixth-century Neoplatonist Scholarch, the last officially appointed Platonic Successor, revert to a tradition that seemingly disappears for well over three centuries?2 In what [End Page 337] follows, I suggest that a plausible historical context for such a reversion can be found in contemporaneous Neoplatonic allusions to Sceptical readings of Plato. I then analyze the Sceptical techniques deployed by Damascius in his critique of Neoplatonist metaphysics, focusing especially on his attacks on Neoplatonic theories of intellect and causation. I conclude by speculating on some ideological factors that shaped Damascius’ Sceptical affiliations, suggesting that here it is possible to see an initial volley in what was to become a centuries-long skirmish between reason and revelation.1. the neoplatonists read the sceptics?R. T. Wallis has suggested that Plotinus borrows from the Sceptics’ arsenal in voicing his own objections against Stoic or Stoicizing epistemology and theology. The seemingly radical stance that Plotinus takes against Stoic notions of divine rationality, virtue, and providence is anticipated by the Sceptics’ refusal to grant that an omniscient mind could stand in need of rational deliberation or exercise virtues that imply the presence of corresponding vices, etc. Not only is it the case that Plotinus makes a detailed use of specific Sceptical arguments in his own polemics against the Stoics, he seems to have been the first philosopher to have grasped the implications of Sceptical challenges to Stoic theology, and to have circumvented Sceptical dilemmas by means of his highly original formulations of nondiscursive thinking and negative theology.That this Platonist might side with Sceptics against dogmatic philosophy would hardly be surprising to the modern student of Plato, but it is also true that historically, this has been an uneasy alliance. In fact, it is just this question, the alliance between Platonists and the Sceptics, that gets rehearsed in the sixth century. Olympiodorus devotes Chapter 10 of his Prolegomena to the Study of Platonic Philosophy to the refutation of an ephectic, or nondogmatic Plato3: “Plato also superseded the philosophy of the New Academy since that school gave precedence to akatalepsia (nonapprehension), while Plato demonstrated that there do exist cognitions grounded in genuine knowledge. Nevertheless, some assert, assimilating Plato to the ephectics and to the Academicians, that he too maintained the doctrine of akatalepsia.” These remarks are curious, for we have no indication that a Sceptical reading of Plato was current or even conceivable at this time. In fact, as the context makes clear, the Sceptics are represented in this passage as a prior philosophical school; chapters 7 through 10 present a concise history of philosophy that is remarkably free from any notions of philosophical currency attributable to any of the views that fall [End Page 338] under its purvue: “there has been no shortage of philosophical haireseis [schools] both before and after Plato, yet he surpassed all of them by his teaching, his thought, and in every possible way”4 (Prolegomena, 7.1).Olympiodorus performs the exegete’s role throughout his refutation of a non-dogmatic Plato, turning first to the grammatical item, Plato’s use of what Olympiodorus terms the “hestitating” adverbs, such as “probably,” “perhaps,” and “as I imagine.” Nevertheless Olympiodorus manages...

To date, no comprehensive account has been published to explain the complex phenomenon of the reception of Aristotle’s philosophy in Antiquity. This Companion fills this lacuna by offering broad coverage of the subject from Hellenistic times to the sixth century AD.

Can the intellect or the intellectual faculty be its own object of thought, or can it not think or apprehend itself? This book explores the ancient treatments of the question of self-intellection - an important theme in ancient epistemology and of considerable interest to later philosophical thought. The manner in which the ancients dealt with the intellect apprehending itself, took them into both the metaphysical and epistemological domains with reflections on questions of thinking, identity and causality. Ian Crystal traces the (...) origins from which the concept of self-intellection springs, by examining Plato's account of the epistemic subject and the emergence of self-intellection through the Aristotelian account, before the final part of the book explores the problem of how the intellect apprehends itself, and its resolution including Plotinus' reformulation and the dilemma raised by Sextus Empiricus. Crystal concludes that Plotinus recasts the metaphysical structures of Plato and Aristotle in such a way that he casts the concept of self-intellection in an entirely new light and offers a solution to the problem.

Emilsson introduces and explains the full spectrum of Plotinus’ philosophy for those coming to his work for the first time. Beginning with a chapter-length overview of Plotinus’ life and works which also assesses the Platonic, Aristotelian and Stoic traditions that influenced him, Emilsson goes on to address key topics including: Plotinus’ originality the (...) status of souls Plotinus’ language the notion of the One or the Good Intellect, including Plotinus’ holism the physical world the soul and the body, including emotions and the self Plotinus’ ethics Plotinus’ influence and legacy. Including a chronology, glossary of terms and suggestions for further reading, _Plotinus _is an ideal introduction to this major figure in Western philosophy, and is essential reading for students of ancient philosophy and classics.

Proclus of Lycia was one of the greatest philosophers of antiquity, producing the most systematic version of late Neoplatonic thought. He exercised enormous influence on Byzantine, medieval, Renaissance and German Classical philosophy, ranking among the top five of ancient philosophers in terms of the number of preserved works. Despite this he is rarely studied now, the enormous intricacy of his system making the reading of his treatises difficult for beginners. This book provides the first comprehensive introduction to all the basic (...) areas of Proclus' thought. It carefully guides the reader through his metaphysics, theology, epistemology and theory of evil, as well as his sophisticated philosophy of religion. It also sets Proclus in the historical, social and religious context of late antiquity, offering a synthetic account that will appeal to historians and students of ancient religion. (shrink)

One of the hardest questions to answer for a (Neo)platonist is to what extent and how the changing and unreliable world of sense perception can itself be an object of scientific knowledge. My dissertation is a study of the answer given to that question by the Neoplatonist Proclus (Athens, 411-485) in his Commentary on Plato’s Timaeus. I present a new explanation of Proclus’ concept of nature and show that philosophy of nature consists of several related subdisciplines matching the ontological stratification (...) of nature. Moreover, I demonstrate that for Proclus philosophy of nature is a science, albeit a hypothetical one, which takes geometry as its methodological paradigm. I also offer an explanation of Proclus’ view of what is later called the mathematization of physics, i.e. the role of the substance of mathematics, as opposed to its method, in explaining the natural world. Finally, I discuss Proclus’ views of the discourse of philosophy of nature and its iconic character. (shrink)

The Pythagorean idea that numbers are the key to understanding reality inspired philosophers in late Antiquity (4th and 5th centuries A.D.) to develop theories in physics and metaphysics based on mathematical models. This book draws on some newly discovered evidence, including fragments of Iamblichus's On Pythagoreanism, to examine these early theories and trace their influence on later Neoplatonists (particularly Proclus and Syrianus) and on medieval and early modern philosophy.

This book is addressed to readers new to the Enneads. One of the greatest of ancient philosophers, Plotinus is attracting ever-increasing attention from those interested in ancient philosophy, late Antiquity, and the importance of this period for the Western intellectual tradition.

In recent years, it has become clear that Proclus has an elaborate metaphysics, not only of the higher realm, but also of the natural world. This chapter first delimits its topic by explaining what physics or philosophy of nature is in Proclus’ view: the hypothetical study of all causes, but especially the transcendent causes of the natural world. After briefly addressing the question whether the world is eternal, the author moves on to presenting these causes in due order: first the (...) many demiurges and other productive causes, the different products of the different demiurgies, the plurality of paradigmatic causes, nature as the proximate cause of bodies, and finally the ontology of bodies, as hylomorphic entities, analysable into immanent forms and different levels of substrate or matter.

A number of philosophers have recently become receptive to the idea that, in addition to scientific or causal explanation, there may be a distinctive kind of metaphysical explanation, in which explanans and explanandum are connected, not through some sort of causal mechanism, but through some constitutive form of determination. I myself have long been sympathetic to this idea of constitutive determination or ‘ontological ground’; and it is the aim of the present paper to help put the idea on a firmer (...) footing - to explain how it is to be understood, how it relates to other ideas, and how it might be of use in philosophy.

Hume thought that if you believed in powers, you believed in necessary connections in nature. He was then able to argue that there were none such because anything could follow anything else. But Hume wrong-footed his opponents. A power does not necessitate its manifestations: rather, it disposes towards them in a way that is less than necessary but more than purely contingent. -/- In this paper a dispositional theory of causation is offered. Causes dispose towards their effects and often produce (...) them. But a set of causes, even though they may succeed in producing an effect, cannot necessitate it since the effect could have been counteracted by some additional power. This would require a separation of our concepts of causal production and causal necessitation. The most conspicuous cases of causation are those where powers accumulate and pass a requisite threshold for an effect to occur. -/- We develop a model for representing powers as constituent vectors within an n-dimensional quality space, where composition of causes appears as vector addition. Even our resultant vector, however, has to be understood as having dispositional force only. This model throws new light on causal modality and cases of prevention, causation by absence and probabilistic causation. (shrink)

This chapter is concerned with Proclus’ understanding of the second Plotinian hypostasis, Intellect—which Proclus’ analysis distinguishes into Being, Life and Intellect proper—as well as with his reception of Plato’s ‘theory’ of Forms within his metaphysics. After a discussion of the general triadic structure of the intelligible world, the author clarifies how Proclus fits the cosmology of the Timaeus, which has been central to all later interpretations of Platonic Forms, into this structure. Next, a presentation of Proclus’ criticism of Aristotle is (...) instrumental in introducing Proclus’ views on the causal role of Intellect and the Forms. The chapter concludes with an exposition of Proclus’ reading of the aporiai of the first part of the Parmenides, which shows how he reinterprets the Platonic ‘theory’ of Forms as it can be found in the dialogues within the conceptual framework expounded in his systematic works.
