PART ONE ALEXANDER OF APHRODISIAS— AN INTRODUCTION A study of a work by Alexander of Aphrodisias must be prefaced by some general introduction to the author ...

Despite the central importance of Alexander of Aphrodisias to later Greek, Medieval, and Renaissance philosophy, little attention has been given to his work in modern times. Only one of his writings, the De fato, has been available in English translation. Todd’s study and translation of Alexander’s De mixtione is therefore a welcome contribution. His book not only contributes to the study of Alexander but also presents a critical analysis of the evidence concerning the theory of the "total blending" of bodies (...) attributed to the Stoics by Alexander and by other ancient sources. By investigating the polemical character of such reports concerning Stoicism, Todd attempts to develop a means of evaluating the evidence, the consequence of which is a revision of not a few aspects of what has been thought to be Stoic doctrine.

Stoic physics, based entirely on the continuum concept, is one of the great original contributions in the history of physical systems. Building on The Physical World of the Greeks, the author describes the main aspects of the Stoic continuum theory, traces its origins back to pre-Stoic science and philosophy, and shows the attempts of the Stoics to work out a coherent system of thought that would explain the essential phenomena of the physical world by a few (...) basic assumptions.

In Stoic physics, blending (κρᾶσις) is the relation between active pneuma and passive matter; natural bodies from rocks and logs to plants, animals and the cosmos itself are blends of pneuma and matter. Blending structures the Stoic cosmos. I develop a new interpretation of the Stoic theory of blending, based on passages from Hierocles. The theory of blending, I argue, has been misunderstood. Hierocles allows us to see in detail how the theory is supposed to work (...) and how it fits into Stoic physics. (shrink)

From the meagre fragments available, Sambursky has carefully reconstructed the basic physical concepts of the Stoa, emphasizing the continuum theory developed by Chrysippos and Poseidonios. Stoic physics, in contrast with Democritean atomism, has been largely neglected, in spite of its relevance to contemporary theories of continuity. Sambursky's contribution should overcome this omission to a great extent, and, together with Mates' and Lukasiewicz's work in Stoic logic, enable us to comprehend the non-ethical features of Stoic thought. Included (...) is a 30 page appendix giving English translations of the relevant classical fragments.--L. S. F. (shrink)

According to the ancient Greek Stoics, the cosmos regularly transitions between periods of conflagration, during which only fire exists, and periods of cosmic order, during which the four elements exist. This paper examines the cosmogonic process by which conflagrations are extinguished and cosmic orders are restored, and it defends three main conclusions. First, I argue that not all the conflagration’s fire is extinguished during the cosmogony, against recent arguments by Ricardo Salles. Second, at least with respect to the cosmogony, it (...) is not necessary to posit the existence of proto-elements. Third, while scholars such as Salles and David Hahm have argued that Cleanthes held a distinct theory of cosmogony from Zeno and Chrysippus, I argue that each of these Stoics endorse the same cosmogonic theory.

In the first part of chapter 2 of book II of the Physics Aristotle addresses the issue of the difference between mathematics and physics. In the course of his discussion he says some things about astronomy and the ‘ ‘ more physical branches of mathematics”. In this paper I discuss historical issues concerning the text, translation, and interpretation of the passage, focusing on two cruxes, the first reference to astronomy at 193b25–26 and the reference to the more physical branches at (...) 194a7–8. In section I, I criticize Ross’s interpretation of the passage and point out that his alteration of has no warrant in the Greek manuscripts. In the next three sections I treat three other interpretations, all of which depart from Ross's: in section II that of Simplicius, which I commend; in section III that of Thomas Aquinas, which is importantly influenced by a mistranslation of, and in section IV that of Ibn Rushd, which is based on an Arabic text corresponding to that printed by Ross. In the concluding section of the paper I describe the modern history of the Greek text of our passage and translations of it from the early twelfth century until the appearance of Ross's text in 1936.

Literature on the Stoa usually concentrates on historical accounts of the development of the school and on Stoicism as a social movement. In this 1977 text, Professor Rist's approach is to examine in detail a series of philosophical problems discussed by leading members of the Stoic school. He is not concerned with social history or with the influence of Stoicism on popular beliefs in the Ancient world, but with such questions as the relation between Stoicism and the thought of (...) Aristotle, the meaning and purpose of such Stoic paradoxes as 'all sins are equal', and the philosophical interrelation of Stoic physics and ethics. There are chapters on aspects of Stoic logic and on the thought of particular thinkers such as Panaetius and Posidonius, but ethical problems occupy the centre of the stage. (shrink)

An overview of the ancient philosophers and their philosophical system (divided into the fields of logic, physics, and ethics) comprising the living, organic, enduring, and evolving body of interrelated ideas identifiable as the Stoic perspective.

This essay considers how ancient Stoic cosmopolitanism – roughly, the claim all human beings are members of the same “cosmopolis”, or universal city, and so are entitled to moral concern in virtue of possessing reason – informs Stoic thinking about how we ought to treat non-human entities in the environment. First, I will present the Stoic justification for the thesis that there are only rational members of the cosmopolis – and so that moral concern does not extend (...) to any non-human part of the natural world – and explore the foundations of these views in Stoic physics. Next, I will show that, like other anthropocentric theories, Stoic cosmopolitanism allows for environmental preservation and protection of non-human entities, so long as these activities ultimately benefit human beings. However, because the Stoics include the appreciation of natural beauty as a component of the happy life, this justification is not as feeble as it might seem. Humans are naturally set up to contemplate the order and complexity of the universe, and so environmental degradation and species loss, in marring this harmonious system, frustrates the achievement of the human goal. After exploring these facets of Stoic philosophy, and assessing to what extent they might justify environmental conservation, I close with a critical appraisal of Stoic theory – specifically, of the claims that (i) only humans possess reason and (ii) only rational creatures are deserving of moral concern.

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)

Argues that the demarcation between humans and animals in Stoicism is made in functional terms, by their different capacities, but also quantitative terms, as smaller or larger shares of pneuma and thus the active principle Gods. Discusses how they Stoics may have related these two categories and makes a case for the possibility to formulate a non-exploitative animal ethic in Stoic terms.

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)

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)

This paper considers what function—if any—colocation of bodies may have in the Stoic theory of blending (κρᾶσις), by examining (1) whether colocation is part of the definition of what blending is; and (2) whether colocation is posited by the Stoics as a requirement necessary for the definition to be satisfied. I reconstruct the standard, Chrysippean definition of blending, and I show that the answer to (1) is ‘no’; further, I argue that the evidence gives no reason to affirm (2). (...) Thus, it appears that colocation does not have a central function in the Stoic theory of blending. (shrink)

This chapter contains sections titled: Introduction The Stoic Logical System Conclusion Bibliography.

The Stoic theory of movement has never been the object of a deep investigation despite the considerable number of sources in Neoplatonist commentators. This paper explores for the first time the Stoic notion of ἐνέργεια, which plays a fundamental role in the Stoic conception of movement and generally in the characterization of interaction between bodies. I will show that the Stoics identified movement and activity, so that everything that is active is necessarily moved. This implies that the (...) Stoics merely characterized ἐνέργεια in a dynamic or kinetic sense, namely by connecting it with movement. In order to prove the coherence of this philosophical position to the Stoic doctrine, I will display the compatibility of Neoplatonists’ reports with other sources. Accordingly, I will claim that the Stoics conceived this peculiar sense of ἐνέργεια in reaction to Aristotle, who clearly distinguished between ἐνέργεια and κίνησις in his physical theory. (shrink)

Deleuze assigns the Stoics a privileged place because they introduced a new orientation for thinking and living that turns the whole story of philosophy inside out. -/- Ryan J. Johnson reveals Deleuze’s provocative reading of ancient Stoicism produced many of his most singular and powerful ideas. For Deleuze, the Stoics were innovators of an entire system of philosophy which they structured like an egg. Johnson structures his book in this way: Part I looks at physics (the yolk), Part II is logic (the shell) and Part III covers ethics (the albumen). Including previously untranslated French Stoic scholarship, Johnson unearths new possibilities for bridging contemporary and ancient philosophy. (shrink)

The paper attempts to introduce the Stoic concept of a deterministic universe and the centrality of the Stoic sage in it, using selected parts of Stoic philosophy (physics of the elements, psychology, causality and hierarchization of causes). The basic line of interpretation is to prove the thesis that the freedom of the sage is based on the autonomy of his manifestations justified by the sovereignly rational disposition of his soul. The author of the paper argues in (...) support of the thesis that akrasia as acting against the order of reason and nature is not possible in the Stoic sage. (shrink)

Scholars have long recognised the interest of the Stoics' thought on geometrical limits, both as a specific topic in their physics and within the context of the school's ontological taxonomy. Unfortunately, insufficient textual evidence remains for us to reconstruct their discussion fully. The sources we do have on Stoic geometrical themes are highly polemical, tending to reveal a disagreement as to whether limit is to be understood as a mere concept, as a body or as an incorporeal. In (...) my view, this disagreement held among the historical Stoics, rather than simply reflecting a doxographical divergence in transmission. This apparently Stoic disagreement has generated extensive debate, in which there is still no consensus as to a standard Stoic doctrine of limit. The evidence is thin, and little of it refers in detail to specific texts, especially from the school's founders. But in its overall features the evidence suggests that Posidonius and Cleomedes differed from their Stoic precursors on this topic. There are also grounds for believing that some degree of disagreement obtained between the early Stoics over the metaphysical status of shape. Assuming the Stoics did so disagree, the principal question in the scholarship on Stoic ontology is whether there were actually positions that might be called "standard" within Stoicism on the topic of limit. In attempting to answer this question, my discussion initially sets out to illuminate certain features of early Stoic thinking about limit, and then takes stock of the views offered by late Stoics, notably Posidonius and Cleomedes. Attention to Stoic arguments suggests that the school's founders developed two accounts of shape: on the one hand, as a thought-construct, and, on the other, as a body. In an attempt to resolve the crux bequeathed to them, the school's successors suggested that limits are incorporeal. While the authorship of this last notion cannot be securely identified on account of the absence of direct evidence, it may be traced back to Posidonius, and it went on to have subsequent influence on Stoic thinking, namely in Cleomedes' astronomy.

The Stoics are famously committed to the thesis that only bodies are, and for this reason they are rightly called “corporealists.” They are also famously compared to Plato’s earthborn Giants in the Sophist, and rightly so given their steadfast commitment to body as being. But the Stoics also notoriously turn the tables on Plato and coopt his “dunamis proposal” that being is whatever can act or be acted upon to underwrite their commitment to body rather than shrink from it as (...) the Giants do. The substance of Stoic corporealism, however, has not been fully appreciated. This paper argues that Stoic corporealism goes beyond the dunamis proposal, which is simply an ontological criterion for being, to the metaphysics of body. This involves, first, an account of body as metaphysically simple and hence fundamental; second, an account of body as malleable and continuous, hence fit for blending (krasis di’ holou) and composition. In addition, the metaphysics of body involves a distinction between this composition relation seen in the cosmology, and the constitution relation by which the four-fold schema called the Stoic Categories proceeds, e.g. the relation between a statue and its clay, or a fist and its underlying hand. It has not been appreciated that the cosmology and the Categories are distinct — and complementary — explanatory enterprises, the one accounting for generation and unity, the other taking those individuals once generated, and giving a mereological analysis of their identity and persistence conditions, kinds, and qualities. The result is an elegant division of Plato’s labor from the Battle of Gods and Giants. On the one hand, the Stoics rehabilitate the crude cosmology of the Presocratics to deliver generation and unity in completely corporeal terms, and that work is found in their Physics. On the other hand, they reform the Giants and “dare to corporealize,” delivering all manner of predication (from identity to the virtues), and that work is found in Stoic Logic. Recognizing the distinctness of these explanatory enterprises helps dissolve scholarly puzzles, and harmonizes the Stoics with themselves. (shrink)

Work in the last decade in the history of philosophy has been characterized by the effort to reclaim texts and make available in English translations and commentaries the full range of philosophical writings of major figures and schools.

ABSTRACT: Although from the 2nd century BC to the 3rd AD the problems of determinism were discussed almost exclusively under the heading of fate, early Stoic determinism, as introduced by Zeno and elaborated by Chrysippus, was developed largely in Stoic writings on physics, independently of any specific "theory of fate ". Stoic determinism was firmly grounded in Stoic cosmology, and the Stoic notions of causes, as corporeal and responsible for both sustenance and change, and (...) of effects as incorporeal and as predicates, are indispensable for a full understanding of the theory. Stoic determinism was originally not presented as causal determinism, but with a strong teleological element, in the context of a theory of natural motions, which makes use of a distinction between a global and an inner-worldly perspective on events. However, Chrysippus also employed his conception of causality in order to explicate his determinism, and can be shown to have maintained a universal causal determinism in the modern sense of the erm. The teleological and mechanical elements of early Stoic determinism were brought together in Chrysippus' conception of fate, which places elements of rationality in every cause. (shrink)

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)

Stoicism is one of the richest and most influential intellectual traditions of antiquity. Leading scholars here contribute new studies of a set of topics which are the focus of current research in this area. They combine careful analytical attention to the original texts with historical sensitivity and philosophical acuity, to provide the basis for a better understanding of Stoic ethics, political theory, logic, and physics.

In this article I investigate what the Stoic doctrine of the two principles, God and matter, owes to Plato. I discuss recent scholarly views to the effect that the Stoics were influenced by Old Academic interpretations of the Timaeus and argue that, although the Timaeus probably did play a role in the genesis of the Stoic doctrine, some role was also played by a dualist theory of flux set forth in the etymologies of the Cratylus. I also discuss (...) Theophrastus’ account of Plato’s achievements in physics (fr. 230 FHS&G) and the report of Old Academic physics contained in Cicero’s Academica, 1. 24–9, and commonly taken to go back to Antiochus of Ascalon, and I show that those reports too are likely to have been influenced by the Cratylus.
