According to Peter van Inwagen, visible inanimate objects do not, strictly speaking, exist. In defending this controversial thesis, he offers fresh insights on such topics as personal identity, commonsense belief, existence over time, the phenomenon of vagueness, and the relation between metaphysics and ordinary language.

Lynne Rudder Baker presents and defends a unique account of the material world: the Constitution View. In contrast to leading metaphysical views that take everyday things to be either non-existent or reducible to micro-objects, the Constitution View construes familiar things as irreducible parts of reality. Although they are ultimately constituted by microphysical particles, everyday objects are neither identical to, nor reducible to, the aggregates of microphysical particles that constitute them. The result is genuine ontological diversity: people, bacteria, donkeys, mountains and (...) microscopes are fundamentally different kinds of things - all constituted by, but not identical to, aggregates of particles. Baker supports her account with discussions of non-reductive causation, vagueness, mereology, artefacts, three-dimensionalism, ontological novelty, ontological levels and emergence. The upshot is a unified ontological theory of the entire material world that irreducibly contains people, as well as non-human living things and inanimate objects. (shrink)

A significant reorientation is currently under way in analytic metaphysics, away from an almost exclusive focus on questions of existence and towards a greater concentration on questions concerning the dependence of one type of phenomenon on another. Surprisingly, despite the central role dependence has played in philosophy since its inception, interest in a systematic study of this concept has only recently surged among contemporary metaphysicians. In this paper, I focus on a promising account of ontological dependence in terms of a (...) non-modal and sufficiently constrained conception of essence developed by Kit Fine. I argue that even this essentialist account is, as it stands, not fine-grained enough to recognize different varieties of dependence which ought to be distinguished even within the realm of ontology. In some cases, an entity may be ontologically dependent on its essential constituents out of which it is constructed; but in other cases, an entity may be ontologically dependent on another for a different reason. A framework which glosses over these differences does not offer a proper diagnosis of why one entity ontologically depends on another. (shrink)

The nature of matter was as intriguing a question for ancient philosophers as it is for contemporary physicists, and Matter, Space, and Motion presents a fresh and illuminating account of the rich legacy of the physical theories of the Greeks from the fifth century B.C. to the late sixth century A.D.

Plato famously promised to complement the Sophist and the Statesman with another work on a third sort of expert, the philosopher--but we do not have this final dialogue. Mary Louise Gill argues that Plato promised the Philosopher, but did not write it, in order to stimulate his audience and encourage his readers to work out, for themselves, the portrait it would have contained. The Sophist and Statesman are themselves members of a larger series starting with the Theaetetus, Plato's investigation of (...) knowledge, and the whole series relies on the Parmenides, the second part of which presents a philosophical exercise, introduced as the first step in a larger philosophical program. Gill contends that the dialogues leading up to the missing Philosopher, though they reach some substantive conclusions, are philosophical exercises of various sorts designed to train students in dialectic, the philosopher's method; and that a second version of the Parmenides exercise, closely patterned on it, spans parts of the Theaetetus and Sophist and brings the philosopher into view. This is the exercise about being, the subject-matter studied by Plato's philosopher. Plato hides the pieces of the puzzle and its solution in plain sight, forcing his students (and modern readers) to dig out the pieces and reconstruct the project. Gill reveals how, in finding the philosopher through the exercise, the student becomes a philosopher by mastering his methods. She shows that the target of Plato's exercise is internally related to its pedagogical purpose. (shrink)

After Plato's Forms, and Aristotle's substances, the Stoics posited the fundamental reality of lekta - the meanings of sentences, distinct from the sentences themselves. This volume analyses the resulting unique, complex, and consistent cosmic view in which lekta are the keystones of the structure of reality: they are all there is to say.

The purpose of this book is to trace the main developments in Greek philosophy during the period which runs from the death of Alexander the Great in 323 B.c. to the end of the Roman Republic. These three centuries, known to us as the Hellenistic Age, witnessed a vast expansion of Greek civilization eastwards, following Alexander's conquests; and later, Greek civilization penetrated deeply into the western Mediterranean world assisted by the political conquerors of Greece, the Romans. But philosophy throughout this (...) time remained a predominantly Greek activity. The most influential thinkers in the Hellenistic world were Stoics, Epicureans and Sceptics. This book gives a concise critical analysis of their ideas and their methods of thought. The last book in English to cover this ground was written sixty years ago. In the interval the subject has moved on, quite rapidly since the last war, but most of the best work is highly specialized. There is a clear need for a general appraisal of Hellenistic philosophy which can provide those who are not specialists with an up-to-date account of the subject. Hellenistic philosophy is often regarded as a dull product of second-rate thinkers who are unable to stand comparison with Plato and Aristotle. This book will help to remove such misconceptions and arouse wider interest in a field which is fascinating both historically and conceptually. (shrink)

This paper seeks to elucidate the distinctive nature of the rational impression on its own terms, asking precisely what it means for the Stoics to define logikē phantasia as an impression whose content is expressible in language. I argue first that impression, generically, is direct and reflexive awareness of the world, the way animals get information about their surroundings. Then, that the rational impression, specifically, is inherently conceptual, inferential, and linguistic, i.e. thick with propositional content, the way humans receive incoming (...) information from the world. When we suspend certain contemporary assumptions about propositional content, the textual evidence can be taken at face value to reveal why, for the Stoics, rational impressions are called thoughts (noēseis) and how the Stoics’ novel semantic entities called lekta (roughly, the meanings of our words) depend on rational impressions for their subsistence.

This comprehensive sourcebook makes available in the original Latin and Greek the principal extant texts required for the study of the Stoic, Epicurean and sceptical schools of philosophy. The material is organized by schools, and within each school topics are treated thematically. The volume presents the same texts (with some additional passages) as are translated in The Hellenistic Philosophers, Volume 1. The authors provide their own critical apparatus, and also supply detailed notes on the more difficult texts. This volume is (...) equipped with a large annotated bibliography. (shrink)

Contre Platon et Aristote, c’est dans les corps que les stoïciens et les épicuriens veulent voir les seules réalités, ce qui agit et ce qui pâtit. Par une espèce de rythme, leur physique reproduit celle des physiciens antérieurs à Socrate. Ainsi les stoïciens rejettent, dans les incorporels, les non-être comme le lieu ou le temps.

This new edition of _Hellenistic Philosophy_--including nearly 100 pages of additional materia--offers the first English translation of the account of Stoic ethics by Arius Didymus, substantial new sources on Epicureanism, Stoicism, and Scepticism, expanded representation of Plutarch and Cicero, and a fuller presentation of papyrological evidence. Inwood and Gerson maintain the standard of consistency and accuracy that distinguished their translations in the first edition, while regrouping some material into larger, more thematically connected passages. This edition is further enhanced by a (...) new, more spacious page design. (shrink)

In this paper, I clarify some central aspects of Stoic thought concerning identity, identification, and so-called peculiar qualities (qualities which were seemingly meant to ground an individual’s identity and enable identification). I offer a precise account of Stoic theses concerning the identity and discernibility of individuals and carefully examine the evidence concerning the function and nature of peculiar qualities. I argue that the leading proposal concerning the nature of peculiar qualities, put forward by Eric Lewis, faces a number of objections, (...) and offer two constructive suggestions which turn upon reconsidering the nature and function(s) of peculiar qualities. Finally, I examine a simple but potent Academic argument against the view that identification requires detecting some attribute(s) unique to the relevant individual. Such an argument is, I argue, largely successful and may have encouraged later Stoics not to think that peculiar qualities enable identification. (shrink)

The surviving sources on the Stoic theory of division reveal that the Stoics, particularly Chrysippus, believed that bodies, places and times were such that all of their parts themselves had proper parts. That is, bodies, places and times were composed of gunk. This realisation helps solve some long-standing puzzles about the Stoic theory of mixture and the Stoic attitude to the present.

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.

In this paper I offer a new interpretation of Stoic ontology. I aim to explain the nature of, and relations between, (i) the fundamental items of their physics, bodies; (ii) the incorporeal items about which they theorized no less; and (iii) universals, towards which the Stoic attitude seems to be a bizarre mixture of realism and anti-realism. In the first half of the paper I provide a new model to explain the relationship between those items in (i) and (ii). This (...) model clears up several problems in Stoicism and gives a precise answer to the question of how bodies and incorporeals differ in their mode of being. The second half of the paper considers the vexed issue of the status of those items in (iii), Stoic universals. (shrink)

In this paper, it is argued the Stoics develop an account of corporeals that allows their theory of bodies to be, at the same time, a theory of causation, agency, and reason. The paper aims to shed new light on the Stoics' engagement with Plato's Sophist . It is argued that the Stoics are Sons of the Earth insofar as, for them, the study of corporeals - rather than the study of being - is the most fundamental study of reality. (...) However, they are sophisticated Sons of the Earth by developing a complex notion of corporeals. A crucial component of this account is that ordinary bodies are individuated by the way in which the corporeal god pervades them. The corporeal god is the one cause of all movements and actions in the universe. (shrink)

The Stoics incorporeals are "somethings" which, albeit nonexistent strictly, are subsistent. For the Stoics things truly existent are bodies. So, the question is: what role do incorporeals play in Stoic ontology? The author endeavors to demonstrate that the interpretation that incorporeals are secondary realities (bodies being the primary ones) is not consistent with Stoic philosophy as a whole. At this point the argument is that bodies and incorporeals serve to complement each other in the sense that one cannot exist without (...) the other. Thus, between them there seems to be a reciprocal dependence. (shrink)

This is a collective study, in nine new essays, of the close connection between theology and cosmology in Stoic philosophy.

This paper rehabilitates the Stoic conception of blending from the ground up, by freeing the Stoic conception of body from three interpretive presuppositions. First, the twin hylomorphic presuppositions that where there is body there is matter, and that where there is reason or quality there is an incorporeal. Then, the atomistic presupposition that body is absolutely full and rigid, and the attendant notion that resistance (antitupia) must be ricochet. I argue that once we clear away these presuppositions about body, the (...) foundations of Stoic corporealism fall into place. Body is fundamental (not hylomorphic). The two fundamental principles (archai) are bodies: divine active reason (logos) and passive matter (hulē); and these two bodies are two, not matter and form all over again, nor actual and potential, but agent and patient. The independence of the two archai is no threat to the unity of the cosmos, however, because the Stoic theory of body allows for the complete coextension of the archai. The hylomorphic thinker rightly asks, what relation could be tighter than that of the wax and its shape? The Stoic replies: a causal relation, the interaction of agent and patient completely coextended in a through and through blend. (shrink)

Ces etudes debordent le probleme du temps chez les Stoiciens et se proposent d'etablir que cette question, en apparence modeste, permet d'eclairer, et en meme temps commande l'ensemble du systeme. Au premier abord en effet, la theorie du temps se presente comme une simple section d'un chapitre de la Physique, celui qui traite des Incorporels. Mais deja la simple interpretation des textes transmis fait voir que cette theorie tient etroitement a d'autres theories, comme celle des incorporels en general, des categories, (...) de la substance. Abordant ensuite les theses majeures de la logique et de l'ethique, on s'apercoit qu'a leur tour elles sont solidaires de la conception du temps qui, dans bien des cas, fait evanouir leur apparence de paradoxe. A cela meme, il n'y a rien d'etrange, si l'on se souvient que le stoicisme, plus que tout autre philosophie antique, constitue un systeme coherent. Mais plus particulierement, le probleme du temps a du former comme le noeud de la reflexion stoicienne qui vise, contre les lourdes autorites de Platon et d'Aristote, a retablir dans sa realite et dans sa dignite, le concret, le sensible, disqualifie comme sujet a la generation et a la corruption, c'est-a-dire, en un mot, comme l'etre dans le temps.

This article is a return to a theme I first tackled in “The Stoic criterion of identity” : the Academics’ ‘Growing Argument’ and the Stoic response to its attack on diachronic identity. This time my aim is to separate out approximately five different stages of the debate between the two schools. This will be done by shifting more of the focus onto developments that seem likely to belong to the late second and/or early first century BC.

The Stoics’ guiding principle in ontology is the Eleatic principle. Their existents are bodies that have the power to act and be acted upon. They account both for the constitution of material objects and the causal interactions among them in terms of such dynamic bodies. Blending is the physical mechanism that explains both constitution and causation; and is facilitated by the fact that for the Stoics all bodies exist as unlimited divided. In this paper I offer a novel analysis of (...) this Stoic stance, and of the role it plays in their metaphysics. I argue that when blended, the substances involved become sharing subjects of qualities and structural features. (shrink)

Book synopsis: Plato is perhaps the most readable of all philosophers. Recent scholarship on Plato has focused attention on the dramatic and literary form through which Plato presents his philosophy, an integral part of that philosophy. The papers in this volume for the first time consider Aristotle and the Stoics as readers of Plato. That these successors were influenced by the thought of Plato is a commonplace: the ‘whole of western philosophy is a series of footnotes to Plato’. Arising from (...) Institute of Classical Studies Research Seminars in 2004-5 and 2005-6, the papers in this volume rather consider whether and how the philosophical concerns of these later thinkers were served were served by close reading of Plato, through inter-textual engagement with specific passages of Plato’s works.

This paper reviews the paper by Kuzma, Najmaie, and Larson that looks at what can be learned from the experience with genetically engineered organisms for oversight of emerging technologies more generally. That paper identifies key attributes of a good oversight system: promoting innovation, ensuring safety, identifying benefits, assessing costs, and doing so all while building public confidence. In commenting on that analysis, this paper suggests that looking at “oversight” in three phases — research and development, regulatory review, and market acceptance (...) — can help to determine when certain of these attributes should take precedence over others and how to structure remedies when an error occurs. The result is an approach that is precautionary with respect to research and development, prudent and open to public input in the regulatory review stage, and purposefully persuasive once market acceptability is at stake, with remedies that are risk-containing in the first phase, risk-managing in the second, and risk-assuaging in the third. Combining the key attributes with the idea of three phases can help attune oversight to society's needs. (shrink)
