Ancient Greek and Roman Metaphysics

In one of his earliest dialogues, the Soliloquia, Augustine identifies the liberal arts (disciplinae) with truth (veritas), and employs this somewhat puzzling identification as a premise in his infamous proof of the immortality of the soul (Sol. 2.24). In this paper, I examine Augustine’s argument for this peculiar identification. Augustine maintains both (1) that the constituent propositions of the liberal arts are true, and (2) that the liberal art of dialectic (disciplina disputandi) is the “truth through which all disciplines are (...) true” (Sol. 2.21). I argue that Augustine identifies the liberal arts with truth because (1) the constituent propositions of the liberal arts are learned, and (2) dialectic’s structure is essential to the liberal arts. I further suggest that the subject matter of each liberal art reflects a distinct segment of intelligible reality, that is, the realm of the intelligible Forms. (shrink)

According to the prevalent scholarly opinion, Eudorus of Alexandria supposes two interrelated levels within the same metaphysical hierarchy: one transcendent principle (to hen) at the highest level and two opposing principles (monas and aoristos dyas) at the subjacent level. This paper presents an alternative interpretation, arguing that Eudorus’ report, in fact, involves two different explanations regarding the first principle(s): one strictly monistic and the other dualistic. Eudorus holds the former approach (the so-called highest teaching, which is particularly influenced by Platonic (...) henotheism) to represent the pinnacle of Pythagorean metaphysics according to which the latter, secondary teaching ought to be construed. In the final analysis, interpreting dualism through the lens of henology results in a somewhat idiosyncratic yet Pythagoreanising account of a Monad and Dyad that are, if understood as principle, identical to the One.

Sophists were active participants in ancient discussions about being or what-is at the most general level. This chapter discusses the contributions of Gorgias, Protagoras, Xeniades, and Lycophron in the context of the Eleatic philosophers Parmenides, Zeno, and Melissus. All of these figures share a serious commitment to ontological inquiry as well as a concern with the problems that arise when discussing being or what-is. They also share an approach to these problems that is at times paradoxical and self-undermining. -/- The (...) chapter begins with a brief discussion of Parmenides’ poem, a work that serves as an important backdrop for later ontology. It then covers Gorgias’ On Not-Being, a response to the Eleatics and a unique contribution in its own right. Gorgias’ work is then compared with that of Zeno and Melissus. Finally, the more limited evidence we have of Protagoras, Xeniades, and Lycophron’s ontological theorizing is discussed. (shrink)

Everything is Something is a book about Stoic metaphysics. It argues that the Stoics are best understood as forging a bold new path between materialism and idealism, a path best characterized as non-reductive physicalism. To be sure, only individual bodies exist for the Stoics, but not everything there is exists — some things are said to subsist. However, this is no Meinongian move beyond existence, to the philosophy of intentionality (as the language of subsistence might suggest), but a one-world metaphysics (...) that both counts its entities by logical criteria, and grounds them in body by physical principles, yielding a tightly ordered ontology in which everything is Something and nothing is not. -/- This last phrase is not innocent. It invokes the Stoic innovation of Something (ti) as the highest genus of reality, and takes the stand that it is not only principled and coherent, but comprehensive — anything that is not Something is nothing at all (for the initiated: there is no class of Not-Somethings between Something and nothing). Further, everything that is Something is either itself a body, or ontologically dependent on body. Herein lies the Stoics’ non-reductive physicalism, and the beating heart of their response to the Battle of Gods and Giants in Plato’s Sophist: a one-world metaphysics. -/- The foundation of Stoic metaphysics is their ground-breaking corporealism, which introduces an alternative to both atomism and hylomorphism. The Stoics are continuum physicists for whom body as such, i.e. solid, three-dimensional extension, is homogeneous, partless, uniform, and infinitely divisible without reaching minima (atoms). And because body is not conceived along hylomorphic lines, i.e. as a composite of matter and form, the Stoics are free to make body fundamental. Out of two basic bodies, then (the archai), and by the tantalizing mechanism of through and through blending (krasis di’ holou), Stoic physics constructs the cosmos (and every body it contains) in completely corporealist terms, composing one thing out of many. And once those bodies are built, Stoic logic gives an account of their identity conditions, kinds, and qualities according to the vexed schema of the Categories, making now many out of one by the constitution relation, as a statue is constituted by its clay. With these distinct mereological relations of composition and constitution, Stoic corporealism artfully divides the labor of Plato’s Forms between physics and logic. -/- Next in the ontological order, with bodies as their foundation, are the incorporeals (asōmata): space (place, room, and surface), time, void, and the (awkwardly named) sayables, or lekta (roughly, though controversially, the meanings of our words). These entities do not exist; they do, however, subsist, inheriting their physical properties and, hence, their subsistence, from the bodies on which they depend. For example, place depends for its three-dimensional (non-solid) extension on the bodies that occupy or delimit it. The ontological dependence of space, time, and their novel semantic entities (the lekta) on body, is what takes Stoic metaphysics beyond corporealism to non-reductive physicalism, beyond a merely sorted ontology to an ordered, one-world metaphysics. Each incorporeal counts as Something according to the Stoic criterion for subsistence (hence, the theory is non-reductive), and what they have in common as incorporeals (and what makes the account physicalist), is their dependence on underlying body. -/- In addition to the incorporeals, the Stoics also recognize the subsistence of things like creatures of fiction and geometrical limits, which they classify as neither corporeal nor incorporeal. What these entities have in common is that they are products of thought; and since thoughts are themselves bodies according to Stoic corporealism, this remains a physicalist account. As before, the account is not Meinongian; neither all objects of thought, nor all products of thought count as Something. Indeed, the Stoics’ eliminative treatment of universals (and Forms) turns on their denying concepts (ennoēmata) a place on the ontological map altogether — concepts are simply not Somethings (and, again, not some further category of Not-Somethings, intermediate between Something and nothing at all). If all this is right, then the Stoics are not flat-footed materialists or ersatz Platonists, as so often assumed, but our first non-reductive physicalists. (shrink)

The argument by which the Eleatic Stranger differentiates the kinds being and different (255c9-e2) is one of the most controversial in Plato’s Sophist. In it the Stranger introduces the vexed distinction between beings that are auta kath’ hauta, ‘themselves according to themselves’, and those that are pros alla, ‘relative to others’ (255c13-14). Although commentators have developed many interpretations of the argument, there is a key yet hitherto unrecognized ambiguity in the syntax of the counterfactual conditional at 255d4-6, concerning whether the (...) adjunct comparative clause, hōsper to on, should be adjoined to the protasis or apodosis. Editors from Heindorf to Robinson adjoin hōsper to on to the protasis. I argue this is mistaken. Adjoining hōsper to on to the apodosis instead allows for a more straightforward interpretation of the argument and offers a resolution to the controversies surrounding the ‘according to themselves’ / ‘relative to others’ distinction.

Review of A.A. Long's translation and commentary of Plotinus's "On Matter" (II.4).

In this paper, I argue that Bryson’s Oikonomikos is a fascinating example of the oikonomia genre in several different respects. Although the problematic transmission of this Neopythagorean text makes studying it a challenge, such effort is well-rewarded with an elaborate argument which paints the human bodily constitution, the central bodily functions and oikonomic activities as intrinsically linked. Focusing on Bryson’s argument which roots oikonomic behaviour in human biology, I explore the underlying conceptualisation of human nature and contextualise it within relevant (...) philosophical and scientific traditions.

The ontology of artefacts in Byzantine philosophy is still a terra incognita. One way of mapping this unexplored territory is to delve into Michael of Ephesus’ commentary on Aristotle’s Metaphysics. Written around 1100, this commentary provides a detailed interpretation of the most important source for Aristotle’s ontological account of artefacts. By highlighting Michael’s main metaphysical tenets and his interpretation of key-passages of the Aristotelian work, this study aims to reconstruct Michael’s ontology of artefacts and present it as one instance, which (...) is perhaps exemplary, of the Byzantine ontology of artefacts. In particular, the study shows that this commentary holds a definite position on the nature of artefacts, according to which they are neither substances nor hylomorphic compounds. Indeed, artefacts lack a form altogether and their forms exist only in thought. As a result, Michael’s commentary provides an ontological interpretation of artefacts as accidental beings, i.e., as matter which acquires a mere property as opposed to a substantial form. While such an interpretation shows originality when compared to the Aristotelian text, it also indicates adherence to the reading established by Alexander of Aphrodisias, despite important departures concerning the status of natural forms.

The American rock band KISS is notorious. Its notoriety derives not only from the band’s otherworldly costumes (except for of course during the unmasked period), the fact that they were inducted into the Rock and Roll Hall of Fame, their numerous hit records or the amazing stage theatrics and pyrotechnics of their live shows. It’s also related to the band’s constantly changing makeup (and I don’t mean the kind on their faces!). Of the four members, only Paul Stanley and Gene (...) Simmons were fixtures. With so many changes to the band’s composition, has KISS always remained the same band? Some see this head-scratcher as roughly similar to a conundrum in philosophical metaphysics (that’s the area of philosophy addressing problems of existence): the puzzle of Theseus’s ship. (shrink)

I examine two startling claims attributed to some philosophers associated with Megara on the Isthmus of Corinth, namely: Ml. Something possesses a capacity at t if and only if it is exercising that capacity at t. M2. One can speak of a thing only by using its own proper A6yor;. In what follows, I will call the conjunction of Ml and M2 'Megaricism' .1 The lit­ erature on ancient philosophy contains several valuable discussions of Ml and M2 taken individually .2 (...) But there is no discussion of them together, much less of their logical relations. I intend to remedy that lack, and to show why it is a lack worth remedying. My aims are both philosophical and historical. Inevitably, in saying anything new and interesting about Megaric views, I will be adopting assumptions scarcely free from controversy, and indulging in quite a bit of charitable recon­ struction. But the resulting picture is of considerable interest. For it explains why, although Ml and M2 seem to have little to do with one another, it is in fact small wonder that anyone who held one would hold the other, for, as I attempt to show, they entail each other. It explains why the Megarics are associated in the primary literature with the names of such diverse philosophical ancestors as Parmenides and Protagoras. And it explains why, although they are both false, Ml and M2 were claims taken seriously by both Plato and Aristotle, who in developing their own views on modality and language saw reason to mention Megaricism, and to argue against it.

Charles E. Snyder considers the New Academy's attacks on Stoic epistemology through a critical re-assessment of the 3rd century philosopher, Arcesilaus of Pitane. Arguing that the standard epistemological framework used to study the ancient Academy ignores the metaphysical dimensions at stake in Arcesilaus's critique, Snyder explores new territory for the historiography of Stoic-Academic debates in the early Hellenistic period. Focusing on the dispute between the Old and New Academy, reveals the metaphysical dimensions of Arcesilaus' arguments as essential to grasping what (...) is innovative about the so-called New Academy. Resisting the partiality for epistemology in the historical reconstructions of ancient philosophy, this book defends a new philosophical framework that re-positions Arcesilaus' attack on the early Stoa as key to his deviation from the metaphysical foundations of both Stoic and Academic virtue ethics. Drawing on a wide range of scholarship on Hellenistic philosophy in French, Italian, and German, Beyond Hellenistic Epistemology builds bridges between analytical and continental approaches to the historiography of ancient philosophy, and makes an important and disruptive contribution to the literature.

Relying upon a very close reading of all of the definitions given in Euclid’s Elements, I argue that this mathematical treatise contains a philosophical treatment of mathematical objects. Specifically, I show that Euclid draws elaborate metaphysical distinctions between substances and non-substantial attributes of substances, different kinds of substance, and different kinds of non-substance. While the general metaphysical theory adopted in the Elements resembles that of Aristotle in many respects, Euclid does not employ Aristotle’s terminology, or indeed, any philosophical terminology at (...) all. Instead, Euclid systematically uses different types of definition to distinguish between metaphysically different kinds of mathematical object. (shrink)

I offer an examination of a core element in the reflectiveness of Heraclitus’ thought, namely, his rebuke of polymathy . In doing so, I provide a response to a recent claim that Heraclitus should not be considered to be a philosopher, by attending to his paradigmatically philosophical traits. Regarding Heraclitus’ attitude to that naïve form of ‘wisdom’, i.e., polymathy, I argue that he does not advise avoiding experience of many things, rather, he advises rejecting experience of things as merely many (...) independent things in their manifoldness , and, instead, to understand their unity and thereby to unify our knowledge of them.

The theory developed by Leucippus (5th cent. BCE), Democritus (470/460-380 BCE), and later Epicurus (341-271/270 BCE) and his school is commonly defined as atomistic materialism. According to this theory, matter is the fundamental principle of existent and ever-evolving reality, and it is constituted of atoms. But whereas for the first atomists atoms were not so much a substance (ousia) as an ideal form (idea) through which they could explain sensible bodies and their movement, with Epicurus atoms effectively turned into a (...) substance. From a mathematical theory we come to a physical conception. (shrink)

In Proclus’ metaphysics, the One produces Being through a mediated set of principles which are the direct causes of Being. While the henads feature prominently as these principles, Proclus posits a second set of principles, the Limit and Unlimited, to explain the aspects of unity and plurality found in all beings. Initially there seems to be a tension in these two sets of principles: Proclus does not immediately clarify how they interact with each other or their relationship to each other. (...) In Elements of Theology Prop. 159, he even seems to say that the Limit/Unlimited produce the henads—which contradicts the henads’ nature as pure ‘ones’. This article analyzes this issue by surveying three contemporary solutions that have been posed to address the tension, while also offering a new alternative: the Limit and Unlimited, as the first henads to emerge from the One, causally determine all subsequent henads according to their respective unique character, while both sets are ultimately derived from the One according to their subsistence —preserving the henads’ natures as simply ‘one’ like the One-itself.

Partiendo de Homero, se emprende una lectura de ciertas tragedias de Sófocles y de Eurípides. Alcestis muere por la belleza; Medea se queda en el aire; la casa se ha corrompido y la pólis ha caído enferma. Para implantar el nuevo proyecto político y apostar con determinación por la igualdad ciudadana, la pólis debía contener el llanto y reprimir las lágrimas por los parientes muertos, lo cual exigía contener y reprimir a las mujeres. Este ensayo intenta comprender en qué sentido (...) la ruptura que define ese proyecto esboza caminos que la pólis misma no está dispuesta a seguir: la erosión de la confianza, la pérdida de la comunidad o la separación de lo ‘económico’; tal como le recuerdan justamente las mujeres.

When did kosmos come to mean *the* kosmos, in the sense of ‘world-order’? I venture a new answer by examining later evidence often underutilised or dismissed by scholars. Two late doxographical accounts in which Pythagoras is said to be first to call the heavens kosmos (in the anonymous Life of Pythagoras and the fragments of Favorinus) exhibit heurematographical tendencies that place their claims in a dialectic with the early Peripatetics about the first discoverers of the mathematical structure of the universe. (...) Likewise, Xenophon and Plato refer to ‘wise men’ who nominate kosmos as the object of scientific inquiry into nature as a whole and the cosmic ‘communion’ (koinônia) between all living beings, respectively. Again, later testimonies help in identifying the anonymous ‘wise men’ by associating them with the Pythagoreans and, especially, Empedocles. As Horky argues, not only is Empedocles the earliest surviving source to use kosmos to refer to a harmonic ‘world-order’ and to illustrate cosmic ‘communities’ between oppositional pairs, but also his cosmology realises the mutual correspondence of these aspects in the cycle of love and strife. Thus, if later figures posited Pythagoras as the first to refer to the universal ‘world-order’ as the kosmos, they did so because they believed Empedocles to have been a Pythagorean natural scientist, whose combined focus on cosmology and ethics exemplified a distinctively Pythagorean approach to philosophy.

There is a tendency among contemporary scholars of ancient Greek philosophy to think that Plotinus’ philosophical orientation is significantly different from that of Plato. One such difference is that Plotinus seems to be more interested in systematically presenting and articulating a specific set of philosophical doctrines than Plato was. After all, Plotinus lived and wrote in a context in which there were a number of highly developed philosophical schools—the Stoics, Peripatetics, Gnostics, and Epicureans, just to name a few—and is interested (...) in showing where his own views stand in relation to these. Yet despite these and other differences between the projects of Plato and of Plotinus, in this paper I want to focus on a point of continuity and agreement between the two: namely on their philosophical orientation toward the ‘why’ (dioti) of things. Plotinus’ philosophical orientation, like that of Plato before him, is driven by a search for the ‘why’ of things and a confidence that the goal of every why-inquiry is attainable. I argue that Plotinus understands this search for the ‘why’ to entail that for every object or state of affairs, there must be some principle that explains why that object or state of affairs is the way it is or has the character it does. In particular, I focus on how Plotinus’ confidence that the object of this sort of why-inquiry is attainable leads him to claim that the first principle—the One or Good—is beyond being. (shrink)

In the Philosophical Anthropology of Gregory of Nyssa, inspired by his Trinitarian Theology, the new concept of hypostasis as a unique self implies for the first time the irreducibility of human person to the universal. Moreover, Gregory manages to account for both a deep communion of life and nature among all men and a clear distinction between persons, in a truly harmonious dynamism of the physical and the hypostatic. This union and distinction will also inspire his original conception of proaíresis, (...) which will express the unique character of each person in the community of nature. Difference and creativity are two of its main features. (shrink)

El presente trabajo se concentra en el debate acerca de los alcances de la providencia que tuvo lugar entre las escuelas estoica, platónica y peripatética entre las siglos I y III de nuestra era. En ese contexto, analiza el problema del status ontológico de los singulares en Orígenes de Alejandría y Nemesio de Émesa. Influidos primariamente por la síntesis filoniana entre las distintas teorías griegas de providencia y la de las Escrituras, estos autores fundan la consistencia de los singulares en (...) la tesis de una acción directa del principio divino sobre cada uno de ellos. Frente a una cierta tendencia universalista y necesitarista del pensamiento clásico, los Padres griegos intentaron rescatar el valor metafísico del individuo en cuanto tal. -/- The present paper focuses on the debate over the scope of Providence that took place among the Stoic, Platonic and Peripatetic schools between the first and the third centuries AD. In that context, it deals with the problem of the ontological status of the singulars in the thought of Origen of Alexandria and Nemesius of Emesa. Influenced primarily by the Philonian synthesis of the different Greek theories of Providence with that of the Scriptures, Origen and Nemesius ground the consistency of individual beings on the thesis of a direct divine action intended for each of them. Faced with the universalistic and necessitarian tendencies of classical thought, the Greek Fathers tried to rescue the metaphysical value of individuals as such. (shrink)

In their chapter, “In What Sense Does the One Exist? Existence and Hypostasis in Plotinus,” Paul DiRado and Michael Wiitala consider the problem of the One’s existence. Starting with the modern philosophical distinction between the “is” of predication and the “is” of existence, they show that Plotinus does not make such a distinction. The reason for this, they argue, is that Plotinus does not share with modern philosophers a univocal notion of existence. For Plotinus, both the verb “einai” and the (...) word “hypostasis” have variable meanings. Thus Plotinus can, in some contexts, say that “the One is” without being committed to the view that the One is or exists in the same way that other entities lower in the metaphysical hierarchy (Forms, say) exist. To say that “the One is” is to say that the One is the basis for the being of other entities; the Forms, on the other hand, truly “are,” in that they are the subjects of necessary and unchanging real predication.

The Greek word ‘schesis’ in the works of Gregory Nazianzen has generally been translated as ‘relation’ and interpreted as a programmatic term for his doctrine of Trinitarian relations. Although this may be a valid interpretation of the terminology of other 4th century theologians, this is not true of Gregory. His usage of the word ‘schesis’ does not correspond with the traditional Aristotelian or Stoic ways of designating a relation. It denotes a status or a disposition, it may even mean a (...) place in a relation, but it is not the relation itself, and not a disposition towards another. Therefore all the interpretations of Gregory’s teaching on the Trinitarian relations are to be revisited and reformulated more carefully, keeping in mind the peculiarity of his usage of ‘schesis.’.

Sources for Stoicism present conflicting accounts of the Stoic principles. Some suggest that the principles are inseparable from each other. Others suggest that they are separable. To resolve this apparent interpretive dilemma, I distinguish between the functions of the principles and the bodies that realize those functions. Although the principles cannot separate when realizing their roles, the Stoic theory of blending entails that the bodies that realize those roles are physically separable. I present a strategy for further work on the (...) principles in light of this interpretation. (shrink)

A study timeshowing that the relation of time and timeless in greek philosophers was more nuanced and complex than is commonly thought.

There are only a few publications devoted to the subject of Heidegger and the Presocratics, some of them already outdated, most of them embedded in Heidegger’s obscure philosophical jargon, and none of them treating the subject exhaustively. Therefore, there is a need for a new, critical presentation of Heidegger’s account of Presocratic thought. However, the purpose of this book is not only to provide such a critical presentation. It raises questions which help us to understand Heidegger as a thinker. The (...) Presocratics provide access to his lifework. -/- The book focuses on Heidegger’s thoughtful repetition of early Greek thinking, and his receptive attention to the fragments of the Presocratics from our contemporary age. Their thought has a special value for him as the heritage which must be repeated anew in order to bring us back to the question of being and to open before us new avenues for existence. The author raises questions which help us to understand Heidegger as a thinker. He presents a deep analysis of Heidegger’s interpretations of the Presocratics and contributes to a new, insightful understanding of Heideggerian philosophy. (shrink)

Peter Lombard lamented the abandonment of Augustine’s position affirming the materiality of demons and the demonic body, since by his time (some 700 years after Augustine), under the influence of the Pseudo-Dionysius, it was generally agreed within the Christian tradition that demons (and angels) are intelligible, disembodied substances. The principles that the cosmos is spatially and materially divided and stratified and that demons share ontologically in the nature of the part that they inhabit allowed figures such as Apuleius, Porphyry, and (...) Augustine to account for various aspects of demonic nature and activity that seemed to follow from reason, revelation, and practical experience. The material body of the demon and its relation to the pneuma, or vehicle of the soul, is often invoked to explain demonic agency and the extent of demonic knowledge and to distinguish between evil and good demons (or angels). The following paper weighs in on and clarifies Augustine’s demonic ontology. Although scholars generally recognise Augustine’s position maintaining that demons possess aerial bodies, nevertheless, the ambiguity surrounding Augustine’s opinion, attested to even by Peter Lombard, is overlooked, and Augustine’s conviction is often taken for granted and supported by citing the prominent City of God, the very work in which Augustine’s own views are suspect. This paper provides support to the assessment of Augustine’s doctrine of the demonic body by examining his cosmology, particularly his spatial and elemental division of the cosmos, and exhibits his adherence to the spatio-material principle according to which a creature’s bodily constitution is cognate with the elemental composition of the physical stratum of the cosmos in which they dwell. The paper concludes by indicating how Augustine’s explanations of demonic agency, far from being ambiguous on the nature of the demonic body, are in fact premised on their aerial corporeality, thereby demonstrating more definitively his conviction that demons possess material bodies.

This is a book review of the book by Sorabji.

Dans ses Confessions, long discours qu’il adresse directement à Dieu, Augustin explique comment l’homme, inquiet de s’être détourné de Dieu par insouciance, aspire intérieurement à retourner à son créateur, et à vivre l’expérience de plénitude associée à ce retour. Mais cette quête est d’abord celle d’Augustin lui-même qui, au IV e siècle, se rappelant les étapes de sa propre conversion au christianisme, évoque deux expériences d’extase qu’il a faites de Dieu, pendant lesquelles il entre en relation directe et charnelle avec (...) la réalité divine. Mais comment de telles expériences mystiques peuvent-elles avoir un caractère aussi sensuel, alors que, selon Augustin, l’ascension vers Dieu suppose justement de l’homme qu’il réussisse à élever son esprit au-delà des tentations charnelles? Le présent article vise à comprendre un peu mieux ce paradoxe. (shrink)

Aristotle introduced in the history of the reception of Anaxagoras the term “homoiomerous.” This word refers to substances whose parts are similar to each other and to the whole. Although Aristotle’s explanations can be puzzling, the term “homoiomerous” may explain an authentic aspect of Anaxagoras’ doctrine reflected in the fragments of his work. Perhaps one should find a specific meaning for the term “homoiomerous” in Anaxagoras, somewhat different from the one present in Aristotle. This requires a review of the sense (...) of the two terms involved in it: “homoios” and “moira.” In other words, the following questions should be answered: what realities are named parts and to what whole do they belong? On the other hand, which similarity do they have to each another and to the whole? The author concludes that the parts are “all things,” which resemble each other and the universe as a whole because, according to Anaxagoras, they are all composed of all things. (shrink)

Spanish translation of Theophrastus' work called Metaphysics.

From its Presocratic beginnings, Western philosophy concerned itself with a quest for unity both in terms of the systematization of knowledge and as a metaphysical search for a unity of being—two trends that can be regarded as converging and culminating in Hegel’s system of absolute idealism. Since Hegel, however, the philosophical quest for unity has become increasingly problematic. Jussi Backman returns to that question in this book, examining the place of the unity of being in the work of Heidegger. Backman (...) sketches a consistent picture of Heidegger as a thinker of unity who throughout his career in different ways attempted to come to terms with both Parmenides’s and Aristotle’s fundamental questions concerning the singularity or multiplicity of being—attempting to do so, however, in a “postmetaphysical” manner rooted in rather than above and beyond particular, situated beings. Through his analysis, Backman offers a new way of understanding the basic continuity of Heidegger’s philosophical project and the interconnectedness of such key Heideggerian concepts as ecstatic temporality, the ontological difference, the turn (Kehre), the event (Ereignis), the fourfold (Geviert), and the analysis of modern technology.

Void is at the heart of Stoic metaphysics. As the incorporeal par excellence, being defined purely in terms of lacking body, it brings into sharp focus the Stoic commitment to non-existent Somethings. This article argues that Stoic void, far from rendering the Stoic system incoherent or merely ad hoc, in fact reflects a principled and coherent physicalism that sets the Stoics apart from their materialist predecessors and atomist neighbors.

I consider an argument by Plotinus to show how the notion of transcendence is used in explaining the nature of knowledge. The argument is set forth in sections 4-6 of the treatise V.8 (31). In my opinion this argument provides a good example of the philosophical frame of Platonism. I sum up this frame in the following theses: a) for a thing being is to be real and true; so that for a thing being real and being true is equivalent; (...) but b) for a thing being real and true means being intelligible; that is to say: a thing could be understood because that thing is a being; thus, c) for a thing being is the identity of its ontological and epistemological nature.

Review of Ancient Concepts of Philosophy by William Jordan.

In his critical study of Speusippus Leonardo Tarán (T.) expounds an interpretation of a considerable part of the controversial books M and N of Aristotle's Metaphysics. In this essay I want to consider three aspects of the interpretation, the account of Plato's ‘ideal numbers’ (section I), the account of Speusippus’ mathematical ontology (section II), and the account of the principles of that ontology (section III). T. builds his interpretation squarely on the work of Harold Cherniss (C.), to whom I will (...) also refer. I concentrate on T. because he has brought the ideas in which I am interested together and given them a concise formulation; he is also meticulous in indicating the secondary sources with which he agrees or disagrees, so that anyone interested in pursuing particular points can do so easily by consulting his book.

Plotinus calls the first principle the One and the Good. According to Plotinus, ‘Good’ is an appropriate name for the One because the One is that which all things desire. Since he says that the One is beyond knowledge, beyond language, beyond intellect, and beyond being, however, what philosophical evidence can he provide for his claim that the One is that which all desire? In this article I offer some philosophical evidence, aside from mystical union with the One, for why (...) ‘the Good’ is an appropriate name for the One, and for why calling the One ‘Good’ is not at odds with the fact that it is beyond knowledge, but rather entails it. To this end, after an initial consideration of the relationship between the good and desire in Plato and Aristotle, I focus on the role that desire plays in relation to the Good in Plotinus’ thought.

Proclus argues that place (topos) is a body of light, identified as the luminous vehicle of the soul, which mediates between soul and body and facilitates motion. Simplicius (in Phys. 611,10–13) suggests that this theory is original to Proclus, and unique in describing light as a body. This paper focuses on the function of this theory as a bridge between Proclus’ physics and metaphysics, allowing the Aristotelian physical notion of “natural place” to serve as a mechanism for the descent and (...) ascent of the soul.
