R. Saadia Ga'on (882–942) de Baghdad tâchait d'éviter l'anthropomorphisme en avançant que les versets bibliques qui semblent attribuer des traits matériels à Dieu portent non sur Dieu Lui-même, mais sur une entité créée, la Gloire de Dieu, que Saadia décrivait comme un “air” extrêmement subtil. Cet article s'efforce de montrer que la conception saadienne d'un air quasi divin, par lequel Dieu accomplit Ses actes dans le monde matériel, est redevable à la doctrine stoïcienne dupneuma. Il s'ensuit que la théologie immanentiste (...) desḤasidey Ashkenaz(Piétistes allemands), que l'on sait avoir été trés influencée par Saadia, est un prolongement lointain de la philosophic et de la physique stoïciennes.

R. Saadia Ga'on, which is known to have been substantially influenced by Saadia, in fine is also indebted to Stoic philosophy and physics.

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.

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.

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)

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)

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)

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.

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.

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.

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)

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)

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.

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)
