Plato: Cosmology

This article concerns the so-called irrigation system in the Timaeus’ biology (77a-81e), which replenishes our body’s tissues with resources from food delivered as blood. I argue that this system functions mainly by the natural like-to-like motion of the elements and that the circulation of blood is an important case study of Plato’s physics. We are forced to revise the view that the elements attract their like. Instead, similar elements merely tend to coalesce with each other in virtue of their tactile (...) features as the atomists describe. The notion of attraction is replaced with this notion of mere coalescence. I begin by outlining how blood is made from food. I then argue that an understanding of health and disease compels us to read Plato as if he were an atomist and to abandon the popular scholarly interpretations according to which the elements attract each other.

In one of the most famous but equally obscure passages in the Timaeus, Plato describes the generation of time and the heavens. The “moving image of eternity” (37d5) is commonly read as Plato’s most general characterisation of time. Rémi Brague famously challenged the traditional interpretation on linguistic grounds by claiming that Plato actually did not conceive of time as an image (εἰκών) but rather as a number (ἀριθμός). In this paper, I shall claim that this controversy is by no means (...) a modern one. The traditional interpretation is mostly owed to Plato’s most prominent reader, Plotinus, who famously conceives of time in relation to eternity (Enn. III.7.13.24-25). Brague’s alternative reading, however, is anticipated by Simplicius’ attempt to refute the Plotinian interpretation, as I shall show. According to my reconstruction, Simplicius’ reading of the Timaeus not only shows why the traditional interpretation falls short, but it also offers a systematic argument that bolsters Brague’s alternative reading. Finally, I shall show that this is consistent with Plato’s text. It shall become clear that current interpretative problems are essentially prefigured in the late ancient debate. (shrink)

This paper concerns the place of Plato’s eschatology in his philosophy. I argue that the theory of reincarnation appeals to Plato due to its power to explain how non-human animals came to be. Further, the outlines of this theory are entailed by other commitments, such as that embodiment disrupts psychic functioning, that virtue is always rewarded and vice punished, and that the soul is immortal. I conclude by arguing that Plato develops a view of reincarnation as the chief tool that (...) the gods have to ensure that virtue is victorious over vice throughout the whole cosmos. (shrink)

I argue that, according to Plato, the body is the sole cause of psychic disorders. This view is expressed at Timaeus 86b in an ambiguous sentence that has been widely misunderstood by translators and commentators. The goal of this article is to offer a new understanding of Plato’s text and view. In the first section, I argue that although the body is the result of the gods’ best efforts, their sub-optimal materials meant that the soul is constantly vulnerable to the (...) body’s influences. In the second section, I argue that every psychic disorder is a disruption of the motions of the inner psychic circles by the body; moreover, I defend my translation of 86b. In the final section, I argue that the goal of education is to restore the circles to their original orbits, and I disarm a possible objection that bad education is also a cause of psychic disorder. (shrink)

I argue that Plato thinks that the soul has location, surface, depth, and extension, and that the Timaeus’ composition of the soul out of eight circles is intended literally. A novel contribution is the development of an account of corporeality that denies the entailment that the soul is corporeal. I conclude by examining Aristotle’s objection to the Timaeus’ psychology and then the intellectual history of this reading of Plato.

In the Timaeus, Plato’s Timaeus offers an account of the sensible world in terms of “images” of forms. Often, images are taken to be particulars: either objects or particular property instances (tropes). Contrary to this trend, I argue that images are general characteristics which are immanent in the receptacle, or bundles of such characteristics. Thus, the entire sensible world can be analysed in terms of immanent general characteristics, the receptacle, and forms. Hence, for Timaeus, fundamentally, there are no sensible particulars. (...) I end by arguing that my interpretation is compatible with Timaeus’ construction of sensible entities from triangles. (shrink)

I defend, against its more recent critics, a literal, factual, and consistent interpretation of Timaeus’ creation of the cosmos and time. My main purpose is to clarify the assumptions under which a literal interpretation of Timaeus’ cosmology becomes philosophically attractive. I propose five exegetical principles that guide my interpretation. Unlike previous literalists, I argue that assuming a “pre-cosmic time” is a mistake. Instead, I challenge the exegetical assumptions scholars impose on the text and argue that for Timaeus, a mere succession (...) of events and the relations derived from it (before, after, simultaneous with) imply no time, given the narrow definition of the term used in the dialogue. For Timaeus, I explain, time is measurable, regular, and dependent on the motion of the celestial bodies. A mere succession of events like the one needed to understand the creation story and the pre-cosmos requires none of these elements. Readers of Plato erroneously assume that a succession of events implies time, but that is to impose a conception of time absent in the text. The chapter offers a detailed reconstruction of the pre-cosmic stage under a literalist interpretation and argues how it is compatible with the immutable relationship between the Demiurge and the cosmos. -/- This is an open access chapter distributed under the terms of the CC BY-NC 4.0 license. chapter 4.

I argue that Plato believes that the soul must be both the principle of motion and the subject of cognition because it moves things specifically by means of its thoughts. I begin by arguing that the soul moves things by means of such acts as examination and deliberation, and that this view is developed in response to Anaxagoras. I then argue that every kind of soul enjoys a kind of cognition, with even plant souls having a form of Aristotelian discrimination (...) (krisis), and that there is therefore no completely unintelligent, evil soul in the cosmos that can explain disorderly motions; as a result, the soul is not the principle of all motion but only motion in the cosmos after it has been ordered by the Demiurge.

The article presents an enquiry into conceptions of ‘global’ that began at the American Society for Cybernetics 2020 Global Conversation conference. Following the traces of Margaret Mead’s statement that emphasized that the first photographic images of the Earth from space presented notions of fragility, the article contextualizes the recent critique of the dominant representation of the Earth as a globe that emerged in conjunction with the discourse on the Anthropocene. It analyses the globe as an image and the sentiments that (...) accompanied it since the first photographs of our planet from space were published in 1968. The article outlines how the cultural meaning of the whole Earth representation changed in parallel with the appropriation of the image by the large technological enterprises that emerged from America’s counterculture. It returns to the possibility of a coexistence of ‘views from within’ and ‘views from without’ following a detour with Gregory Bateson via Bali and proposes a Cybernetics of Grace as a practice of resistance against pure exteriority. The article concludes by linking the Cybernetics of Grace with the second-order conversations of Gordon Pask. (shrink)

Of all the criticisms that Aristotle gives of his predecessors’ theories of soul in De anima I.3–5, none seems more unmotivated than the ones directed against the world soul of Plato’s Timaeus. Against the current scholarly consensus, I claim that the status of Aristotle’s criticisms is philosophical rather than eristical, and that they provide important philosophical reasons, independent of Phys. VIII.10 and Metaph. Λ.6, for believing that νοῦς is without spatial extension, and that its thinking is not a physical motion.

The ‘traditional’ interpretation of the Receptacle in Plato’s Timaeus maintains that its parts act as substrata to ordinary particulars such as dogs and tables: particulars are form-matter compounds to which Forms supply properties and the Receptacle supplies a substratum, as well as a space in which these compounds come to be. I argue, against this view, that parts of the Receptacle cannot act as substrata for those particulars. I also argue, making use of contemporary discussions of supersubstantivalism, against a substratum (...) interpretation that separates substratum and space in the Timaeus. (shrink)

A new volume on one of the most influential and most discussed works from antiquity should offer something new. In this truly interdisciplinary volume, a great number of intriguing problems posed by Plato's Timaeus are given a fresh and lucid treatment. Contributors from an unusual range of backgrounds reflect on aspects of Plato's astounding synthesis of natural philosophy, including cosmology, theology, perception, physiology, and more. Plato's synthesis was original, reusing previous ideas for a new vision of the structure and coherence (...) of the physical world: his "likely account" (Tim. 29bc) (as he preferred to call it) showed that a Maker or Creator used a form of "geometric atomism" to build up the universe ..

The article aims at demonstrating that in attributing the creatio ex nihilo to both Plato and Aristotle as their unanimous philosophical conviction the Treatise on the Harmony between the Two Sages deeply depends upon the Neoplatonic reading of those two philosophers. The main obstacles for such a view in the works of the two sages are Plato's assumption of a precosmic chaos in the Timaeus and Aristotle's denial of any efficient causality to the unmoved mover in the Metaphysics. Both of (...) these points had been, however, done away with by the Neoplatonist commentators already, especially by Ammonius in his lost treatise on efficient and final causality in Aristotle the use of which in the Harmony is shown by a comparison with Simplicius. Christian and Muslim readers just had to transfer those arguments and hermeneutical techniques into an anti-eternalist context in order to make the two philosophers agree with one of the basic tenents of their face, a hermeneutical technique considerably different from the one employed by al-Fārābī in his exposition of Plato's and Aristotle's philosophy which is compared to the Harmony in a briefly sketched concluding section.L'article vise à montrer que le Traité sur l'harmonie des deux sages, en attribuant la creatio ex nihilo à Platon et Aristote comme conviction philosophique commune, dépend profondément de la lecture néoplatonicienne de ces deux philosophes. Les obstacles principaux à une telle attribution dans les œuvres des deux sages sont, dans le Timée de Platon, l'affirmation d'un chaos précosmique et, dans la Métaphysique d'Aristote, la négation d'une causalité efficiente du premier moteur immobile. L'interprétation néoplatonicienne avait toutefois éliminé chacune de ces affirmations de la doctrine des deux maîtres, comme le montre en particulier le traité d'Ammonius sur la causalité finale et efficiente chez Aristote. Or, on peut montrer, par une comparaison avec Simplicius, que l’Harmonie faisait usage de ce traité. Les philosophes chrétiens et musulmans avaient ainsi la possibilité d'employer les mêmes arguments et méthodes herméneutiques pour établir une concordance entre les deux principales autorités philosophiques d'une part et une de leurs plus importantes convictions religieuses d'autre part – une herméneutique qui diffère considérablement de la méthode appliquée par al-Fārābī dans sa propre exposition des philosophies de Platon et d'Aristote, comme le montre, dans la conclusion de l'article, la brève comparaison avec l’Harmonie.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

This paper aims to show that—and how—Plato’s notion of the receptacle in the Timaeus provides the conditions for developing a mathematical as well as a physical space without itself being space. In response to the debate whether Plato’s receptacle is a conception of space or of matter, I suggest employing criteria from topology and the theory of metric spaces as the most basic ones available. I show that the receptacle fulfils its main task–allowing the elements qua images of the Forms (...) to exist as sensible things by being that in which the elements appear, change and move–in virtue of being pure continuity. All further qualifications required for a full notion of space are derived solely from the content of the receptacle. (shrink)

Plato's Timaeus is one of the most influential and challenging works of ancient philosophy to have come down to us. Sarah Broadie's rich and compelling study proposes new interpretations of major elements of the Timaeus, including the separate Demiurge, the cosmic 'beginning', the 'second mixing', the Receptacle and the Atlantis story. Broadie shows how Plato deploys the mythic themes of the Timaeus to convey fundamental philosophical insights and examines the profoundly differing methods of interpretation which have been brought to bear (...) on the work. Her book is for everyone interested in Ancient Greek philosophy, cosmology and mythology, whether classicists, philosophers, historians of ideas or historians of science. It offers new findings to scholars familiar with the material, but it is also a clear and reliable resource for anyone coming to it for the first time. (shrink)

One aim of this paper is to bring to the surface the problems with the traditional, non-literal interpretation of the pre-cosmos in the Timaeus. Contrary to this traditional interpretation, I show that Necessity is an ateleological cause capable of bringing about the events in the pre-cosmos, and that Intelligence is a teleological cause that produces effects only for the sake of maximizing the good. I conclude that there are no grounds for supposing that Intelligence is a causal force operating in (...) the pre-cosmos, and that the account of the pre-cosmos should be taken literally: it is an account of the works of Necessity alone.

The much-anticipated anthology on Plato’s_Timaeus_—Plato’s singular dialogue on the creation of the universe, the nature of the physical world, and the place of persons in the cosmos—examining all dimensions of one of the most important books in Western Civilization: its philosophy, cosmology, science, and ethics, its literary aspects and reception. Contributions come from leading scholars in their respective fields, including Sir Anthony Leggett, 2003 Nobel Laureate for Physics. Parts of or earlier versions of these papers were first presented at the (...) _Timaeus_ Conference, held at the University of Illinois at Urbana–Champaign in September of 2007._ To this day, Plato’s _Timaeus_ grounds the form of ethical and political thinking called Natural Law—the view that there are norms in nature that provide the patterns for our actions and ground the objectivity of human values. Beyond the intellectual content of the dialogue’s core, its literary frame is also the source of the myth of Atlantis, giving the West the concept of the “lost world.” From Platonic space to Presocratic vortices, from Philosopher-Kings to Craftsman-Gods and from modern physics to the myth of Atlantis, _One Book, The Whole Universe_ presents in one volume the most up-to-date and penetrating scholarship on Plato’s _Timaeus_ by some of the greatest minds alive today.

A collection of essays from major scholars in the field as well as from people in a wide range of other disciplines to which the Timaeus and its reception have been of relevance, from architecture and film studies to physics.

This paper argues that processes in the sensible realm can be in accord with reason in the Timaeus, since rationality is understood here as being based on regularity, which is conferred onto processes by time. Plato uses two different temporal structures in the Timaeus, associated with the contrast there drawn between Greek and Egyptian approaches to history. The linear order of before and after marks natural processes as rational and underlies the Greek treatment of history. By contrast, a bidirectional temporal (...) structure is the basis for the Egyptian approach to historical processes: present actions are not only determined by preceding ones in the past, but can also be influenced by the future (plans, aims). This latter temporal structure is shown to be necessary for learning from history, which makes human actions more regular. (shrink)

Immediately upon the death of Plato in 347 BCE, philosophers in the Academy began to circulate stories involving his encounters with wisdom practitioners from Persia. This article examines the history of Greek perceptions of Persian wisdom and argues that the presence of foreign wisdom practitioners in the history of Greek philosophy has been undervalued since Diogenes Laertius.

The paper offers an interpretation of Plato’s Necessity in the Timaeus according to which Necessity is an entity which manifests itself in different ways at different stages of the creation of the Universe. The main argument aims to show that Necessity gains at least two different meanings in the course of the creation as described by Plato – that of limiting consequences and that of purposeless motion ; that despite the fact that Necessity is not a self-sustained principle, it has (...) its origin in chōra which is a condition of limiting material spatiality; that the important question what the effects of Necessity in the already created world are should be asked but cannot be easily answered on the basis of what Plato explicitly says.

In this article I analyze a traditional interpretation of Platonic philosophy, which assumes a "theory of two worlds." I try to prove that it is difficult to accept such an interpretation. If one can say that the on tic status of ideas differs from the ontic status of undefined matter (the phenomenon is always for Plato a relation, a compositum, of idea and undefined matter), one nevertheless cannot say that accepting this necessarily results in accepting two independently existing worlds. For (...) then what would phenomena be, if they lacked the ideas that are the source of their determination; and what would ideas themselves be, if they referred to something other than the subject of their determination? Plato always opted for the existence of one world, although this world was for him ontically complex. (shrink)

Although a great deal has been written on Plato's ethics, his cosmology has not received so much attention in recent times and its importance for his ethical thought has remained underexplored. By offering accounts of Timaeus, Philebus, Politicus and Laws X, the book reveals a strongly symbiotic relation between the cosmic and human sphere. It is argued that in his late period Plato presents a picture of an organic universe, endowed with structure and intrinsic value, which both urges our respect (...) and calls for our responsible intervention. Humans are thus seen as citizens of a university that can provide a context for their flourishing even in the absence of good political institutions. The book sheds light on many intricate metaphysical issues in late Plato and brings out the close connections between his cosmology and the development of his ethics. (shrink)

This volume is a study of the influence of Timaeus on the development of Western cosmology in three axial periods of European culture: Late Antiquity, Middle Ages and Renaissance.

In welchem Verhaltnis steht die Seelenlehre zur Kosmologie in Platons Phaidon?

Dans le Timée, l'hypothèse de la khó̱ra, qu'il faut se garder d'identifier avec la húle̱ aristotélicienne, permet de rendre compte du fait que les choses sensibles sont radicalement différentes de leur modèle intelligible. Or, la constitution mathématique des éléments à partir de la khó̱ra mène à la contradiction suivante : dans l'univers platonicien, il faut tenir compte à la fois du continu qui doit caractériser la khó̱ra, et du discontinu qu'instaurent inéluctablement les polyèdres réguliers auxquels sont associés les éléments. La (...) physique platonicienne n'est donc ni un atomisme, comme celui proposé par Leucippe et Démocrite, ni une physique du continu, comme celle admise par Parménide et Zénon. In the Timaeus, the hypothesis of khó̱ra, which we must refrain from identifying with Aristotelian húle̱, enables us to account for the fact that sensible things are radically different from their intelligible model. Yet the mathematical constitution of the elements from khó̱ra leads to the following contradiction : in the Platonic universe, we must take into account both the continuity that must characterize khó̱ra and the discontinuity inevitably introduced by the regular polyhedra with which the elements are associated. Platonic physics is thus neither an atomism, like that proposed by Leucippus and Democritus, nor a physics of continuity, like that held by Parmenides and Zeno. (shrink)
