Stoics: Metaphysics and Physics

The purpose of this paper is to identify the upholders of the thesis reported by Plutarch, De Stoicorum repugnantiis 23, aimed to reject Stoic determinism. A brief introduction will be devoted to the relationship between this text and the more general context of the Stoic philosophy. Then, I will take into account the objection against Stoic determinism raised by some anonymous philosophers: according to it, causal determinism would be inconsistent with the choice among indistinguishables. Chrysippus replied that if that choice (...) were not determined, it would occur without causes; and this would be absurd. Then I will summarize the most likely hypotheses about the identification of Chrysippus’ opponents, and I will opt for Academics. Finally, I will try to conjecture the link between Plutarch’s passage and the debate among Stoics and Academics about indistinguishables, as we know it from other sources. (shrink)

This paper traces how the dualism of body and soul, cosmic and human, is bridged in philosophical and religious traditions through appeal to the notion of ‘breath’ (πνεῦμα). It pursues this project by way of a genealogy of pneumatic cosmology and anthropology, covering a wide range of sources, including the Pythagoreans of the fifth century BCE (in particular, Philolaus of Croton); the Stoics of the third and second centuries BCE (especially Posidonius); the Jews writing in Hellenistic Alexandria in the first (...) century BCE (Philo); and the Christians of the first century CE (the gospel writers and Paul). Starting from the early Pythagoreans, ‘breath’ and ‘breathing’ function to draw analogies between cosmogony and anthropogony – a notion ultimately rejected by Plato in the Timaeus and Aristotle in his cosmological works, but taken up by the Posidonius (perhaps following the early Stoa) and expanded into a rich and challenging corporeal metaphysics. Similarly, the Post-Hellenistic philosopher and biblical exegete Philo of Alexandria, who was deeply influenced by both Platonist and Stoic physics, approaches the cosmogony and anthropogony described in Genesis (1:1–3 and 1:7) through Platonist-Stoic philosophy, in his attempt to provide a philosophically rigorous explanation for why Moses employed certain terms or phrases when writing his book of creation. Finally, the chapter sees a determined shift in the direction of rejecting pneumatic cosmology for a revised pneumatic anthropogony in the writings of the New Testament: by appeal to the ‘Holy Spirit’ or ‘Holy Breath’ (πνεῦμα ἅγιον), early Christians effectively adapted the Stoic metaphysics of ‘breath’, with its notions of divine intelligence and bonding, to the prophetic and ecclesiastical project of building a Christian community conceived of as the ‘body of Christ’. Hence, the spiritual cosmogony of the Pythagoreans, Stoics, and Philo is effectively subordinated to the spiritual anthropogony that facilitates the construction of the Christian kosmopolis, only fully realised in the form of New Jerusalem, the ‘bride’ which, in tandem with the Holy Spirit, calls to the anointed. At the end of the Christian worldview, the kosmos of Greek philosophy is supplanted by the pneumatic kosmopolis. (shrink)

Can the Stoic conception of what is within our power be adapted to fit our scientifically informed view of nature in general and of human nature in particular? This paper argues that it can, but not without a revision of the Stoic’s classical dichotomy of power principle, namely that some things are up to us, while others are beyond our control. Given the extent to which the Stoic way of life flows from a certain conception of what is real, a (...) revision of the latter is bound to affect the former. The central argument is that for the modern Stoic, follow the facts means that nothing is entirely under our control just as nothing is entirely beyond it. Rather, things are more or less within my power, depending on the range of possibilities that living in accordance with a constantly evolving conception of nature affords. (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.

Ésta es la respuesta a la crítica hecha por Ricardo Salles a mi interpretación del compatibilismo estoico. Aunque en parte admito sus objeciones, intento mostrar que algunos textos nos permiten pensar que, aunque lo que depende de nosotros no implique necesariamente acciones alternativas, eso no significa que no pueda implicarlas. También trato de mostrar que un reexamen de la noción crisipea de posibilidad que tenga en cuenta el deseo y la creencia permite explicar por qué no es posible llevar a (...) cabo las acciones X e Y en un tiempo dado, lo cual indicaría que la posibilidad específica también excluye acciones alternativas. /// This is the reply to Ricardo Salles' criticism of my interpretation of the Stoic compatibilism. Although I partially admit his objections, I intend to show that some texts allow us to think that, even though what depends on us does not necessarily imply alternative actions, this does not mean that it can not imply them. I also endeavour to show that a re-examination of the Chrysippean notion of possibility taking into account desire and belief permits to explain why it is not possible to perform the actions X and Y in a given time, which would indicate that the specific possibility rules out alternative actions as well.

Este trabajo discute la interpretación de Marcelo Boeri sobre el compatibilismo estoico; esto es, la tesis de que es compatible con el determinismo que rige al mundo natural el que podamos ser genuinamente responsables de nuestras acciones. Según Boeri, los estoicos intentaron conciliar las dos cosas abriendo un margen de indeterminación gracias al cual nuestras acciones no están sujetas a la necesidad que domina los demás fenómenos naturales. La discusión que se ofrece aquí se basa en un análisis del concepto (...) antiguo de lo que depende de nosotros y de los conceptos estoicos de determinismo y modalidad. /// This paper discusses Marcelo Boeri's interpretation of Stoic compatibilism, the thesis that natural determinism does not rule out that we can genuinely be responsible for our actions. According to Boeri, the Stoic hold that this is so because our actions are to a great extent free from determination. The discussion of this interpretation is based on an analysis of the ancient concept of what depends on us and of Stoic concepts of determinism and modality. (shrink)

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)

Reconstructs the original Greek version of the confatalia-argument that Cicero attributes to Chrysippus in De fato and misrepresent in crucial ways. Compares this argument with Seneca's discussion of determinism in the Naturales quaestiones. Clarifies that Seneca makes a different distinction from that attested in Cicero's De fato. Argues that problems with interpreting both accounts derive from disregarding terminological distinctions harder to spot in the Latin versions and, related to this, insufficient attention to the ontological distinction between bodies (such as Fate) (...) and predicates (e.g. "what is fated"), which unfortunately does not square well with the modern ontological category "event." Contains some corrections to the author's earlier discussion of the topic in Seneca und die Stoa: Der Platz des Menschen in der Welt, De Gruyter 2006, ch. 3.3.4. (shrink)

Relates Stoic changing conceptions of time to these philosophers’ theology. Roughly speaking, we can distinguish a first phase in which the original definition by Zeno was developed and refined, and a second phase, beginning with Posidonius at the latest, in which new concepts of both objective and subjective time were introduced that turned out to be incompatible with the strictly "corporealist" ontology into which the original definitions had been embedded. The early Stoics defined time in dependence of moving bodies in (...) such a way that the subsistence of times, their structural coherence and unity within the whole time of the cosmos's movement as well as the division of time into past, present and future were a consequence of god's activities. It was god who determined time and what it was like. Maybe under the influence of Aristotle, some middle Stoics and in particular Posidonius seem to have become dissatisfied with the idea that there are only times of single movements but no time as a universal temporal dimension. They introduced a distinction between objective time and - both perceptually and conceptually - subjective time as well as the concept of a now that implies both a point-like division between past and future and a defined location for the present within objective time. As a consequence, God's activities are now structured by a temporal dimension that does no longer depend of God in all its aspects. Now, God too has a past and a future, and his activities can be analyzed in terms of necessity and possibility. This raises questions about divine agency similar to those discussed in order to define human responsibility and freedom of action. Reflexes of such a debate about the determinedness of god's activities can be observed in the imperial Stoic Seneca. (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.

Demonstrates the sophistication of Seneca’s Stoicism by setting his contributions within the context of his school. Seneca’s contributions to physics, metaphysics, logic, determinism, theodicy and eschatology are set within a systematic reconstructions of Stoic positions. Ample documentation of sources and scholarship as well as the thematic, handbook-like structure allow for this book to be used as a look-up tool and introduction to the Stoic cosmos and the place of humans within it. -/- There are a number of new readings and (...) interpretations, e.g. concerning the corporeality of the principles; mixture (krasis di’ holôn); the elements and pneuma; identity; the relation of God and humans; Seneca’s attitude to logic; Seneca’s philosophy of time; the role of lekta in defining reality and action; Stoic and Senecan theodicy; Seneca’s contribution to the determinism debate.

Chrysippus often talks as if there is a third option when we might expect that two options in response to a question are exhaustive. Things are true, false or neither; equal, unequal, or neither; the same, different, or neither.. and so on. There seems to be a general pattern here that calls for a general explanation. This paper offers a general explanation of this pattern, preserving Stoic commitments to excluded middle and bivalence, arguing that Chrysippus employs this trichotomy move when (...) he wishes to argue that apparent contradictories are only contraries, and wishes to endorse a third option. This general explanation of the pattern of trichotomies sheds light on a number of interpretive puzzles, including on Chrysippus's response to the paradox of the cone. The purpose of these trichotomies is also discussed, and it is suggested that they originate from the dialectical context in which philosophical problems were posed. (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)

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)

How does God think? How, ideally, does a human mind function? Must a gap remain between these two paradigms of rationality? Such questions exercised the greatest ancient philosophers, including those featured in this book: Socrates, Plato, Aristotle, the Stoics and Plotinus. This volume encompasses a series of studies by leading scholars, revisiting key moments of ancient philosophy and highlighting the theme of human and divine rationality in both moral and cognitive psychology. It is a tribute to Professor A. A. Long, (...) and reflects multiple themes of his own work. (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)

One of Leibniz’s more unusual philosophical projects is his presentation (in a series of unpublished drafts) of an argument for the conclusion that a time will necessarily come when “nothing would happen that had not happened before." Leibniz’s presentations of the argument for such a cyclical cosmology are all too brief, and his discussion of its implications is obscure. Moreover, the conclusion itself seems to be at odds with the main thrust of Leibniz’s own metaphysics. Despite this, we can discern (...) a serious and important point to Leibniz’s consideration of the doctrine, namely in what it suggests about the proper boundary between metaphysics and theology, on the one hand, and ordinary history (whether human or natural), on the other. And we can get a better sense of Leibniz purpose in the essays by considering them in the context of Leibniz's response to Thomas Burnet's "Telluris theoria sacra" (1681-89). Leibniz praises Burnet's history of earth for presenting a harmony between the principles of nature and grace, a harmony absent in the cosmogonies of Descartes and the Newtonians. But Leibniz also complains that Burnet misconceives the boundary between natural explanation and reflections on divine wisdom. And Leibniz's essays on cyclical cosmology suggest the alternative to Burnet's account: a natural history of the earth and its inhabitants should be radically autonomous from, even if ultimately harmonious with, theological principles.

My ultimate purpose here is to examine, discuss, and interpret a difficult excerpt in Stobaeus’ 5th c. AD anthology, alleging to report—uniquely, it appears—a distinction Chrysippus drew between three different applications of the term stoixe›on or element (i.e., physical element).1 Stobaeus lists this passage as giving opinions specifically of Chrysippus “about the elements out of substance” (per‹ t«n §k t∞w oÈs€aw stoixe€vn), though in holding them he says Chrysippus was following Zeno, the leader of his sect. Hermann Diels (1879) identified (...) this selection as an excerpt (his fr. 21) from Arius Didymus’ late first century BC Epitome of Physical Doctrines.2 I print a translation below, with the text in an Appendix, as it is given in von Arnim (1903). The text is not without its problems, and I indicate in footnotes to the text which of the principal editors’ textual interventions I accept and follow in my translation. Whether this text presents a single, continuous excerpt from Arius Didymus, or instead some compilation of Stobaeus (or an earlier anthologist whose work Stobaeus employed) from dispersed passages of..

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.

L’article analyse les témoignages stoïciens qui définissent la divinité comme «intellect» et comme «âme du monde», et qui permettent de déterminer les contenus de la pensée divine comme logoi, c’est-à-dire certains «discours» ou «raisonnements». En premier lieu, on examine les mots νοερόν, et νοητόν pour établir à quelles réalités les Stoïciens confèrent les caractères d’intelligence et d’intelligibilité et comment ils décrivent la pensée scientifique à laquelle ils comparent la pensée divine. En second lieu, on examine la théorie des raisons séminales (...) et ses relations historiques avec le problème des objets de la pensée divine. Enfin, on tente de montrer que les Stoïciens, tout en suivant la théologie démiurgique du Timée, unifient ce que Platon a tenu bien séparé : le Démiurge lui-même, l’âme du monde, le «vivant intelligible».

The purpose of the present article is to show that there is a clear line of continuity between the early Stoics’ and Cornutus’ works, as all of them assumed that the ancient mythmakers had transformed their original cosmological conceptions into anthropomorphic deities. Hence, the Stoics from Zeno to Cornutus believed that the names of the gods reflected the mode of perceiving the world that was characteristic of the people who named the gods in this way. Accordingly, the major thesis advanced (...) in the paper proposes that the Stoics conducted their etymological analyses so as to gather ethnographical information about the origin and development of the existing religion. When doing so, they treated the conventional mythological narratives as sources of information about the early conceptions of the cosmos. Th us, the Stoics from Zeno to Cornutus employed etymology as a certain research strategy: they analyzed the names of traditional deities so as to extract the physical and moral beliefs that constituted the ancients’ world picture. Treated as ethnologists, the Stoics seem to equate piety with retrieving philosophical truths obscured under the guise of primitive mythical formulations. Furthermore, when unravelling the original worldview inadvertently transmitted by the poets in their poems, the Stoics reconstruct the history of religion and contribute to the development of ancient anthropology.

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

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)

Meijer's book, a comprehensive study of Stoic theological arguments, defends the thesis that the Stoics were not narrowly interested in proving the existence of a god. The theology of the Stoa began with its founder, Zeno of Citium, presenting arguments that the cosmos is an intelligent being, though Zeno himself seems not to have explicitly identified that intelligent being as god. A clear statement equating the cosmos with god had to wait until the rise of the third head of the (...) school, Chrysippus, though Meijer acknowledges that there is no reason to think that Zeno or Cleanthes, the second head, would have opposed the proposition that the cosmos, or at least the rational fire that pervades it, is god. Confusion about the true intent of Zeno's arguments is due to their distortion in the sources, for example, by Sextus Empiricus, who, Meijer contends, presents several of Zeno's arguments for the rationality of the cosmos as if they were intended as arguments to establish the existence of god. As a result, Sextus is an unreliable witness for determining the point of these arguments. Further confusing matters is the existence of a set of arguments attributed to Zeno that aim to establish the existence of the traditional gods. Meijer. (shrink)
