Plato: Cosmology

Plato's educational model (paidèia) differentiates the level of education according to the students' skills. Thus, a basic education includes, in addition to gymnastics and fighting (the exercise of the body), music (the exercise of the spirit), without being imposed by force because a free man must be free in the conquest of knowledge. If the student has skills, he is educated in mathematics to become a strategist, and in astronomy to raise the soul. From these, the best are selected to (...) become good leaders, studying philosophy and dialectics. Women will have the same rights and duties as men. According to Socratic principles, in order to do justice, one must know what is good, and this is best known to the philosopher. Plato detailed this concept, highlighting the distinction between the philosopher (who seeks the principles of truth without claiming to possess it) and the sophist (who lets himself be guided by opinion as the only valid parameter of knowledge). Plato considers philosophers to be ideal leaders for two main reasons: because they know what is right, and because they do not want to lead. -/- DOI: 10.13140/RG.2.2.17459.71200. (shrink)

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.

I develop an account of the role that biology plays in the Timaeus’ view of nous and other aspects of cognitive life. I begin by outlining the biology of human cognition. I then argue that these biological views shine an important light on different aspects of the soul. I then argue that the human body is particularly friendly to nous, paying special attention to the heart and the liver. I next consider the ways that the body fails to protect our (...) nous. I conclude by comparing human nous with the cognition of non-humans. (shrink)

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)

In the Timaeus, Plato famously acknowledges the receptacle as extremely difficult to comprehend. It is neither intelligible (which is reserved exclusively for the Forms) nor sense-perceptible (as it is a principle far too basic). Instead, as Plato proposes, the receptacle can only be apprehended through a “bastard” sort of “reasoning” (νόθος λογισμός, Tim. 52b1-2.). This paper explores an exegesis of Plato’s claim as offered by Calcidius, the 4th century translator of and commentator on the Timaeus. I identify two distinctive methods (...) Calcidius advances when grappling with the knowability of the material substratum that underpins our world. The first method – analysis (resolutio) – traces its intellectual lineage to earlier philosophical tradition, and Calcidius primarily uses it to uncover the proper nature and ontological characteristics of matter. Conversely, the second method corresponds to the only cognitive grasp of matter Calcidius believes humans are capable of. In his view, we can neither sense-perceive nor rationally understand matter. Instead, matter yields itself only to the cognitive mode of suspicion (suspicio). The paper provides a detailed analysis of Calcidius’ suspicio, delving into its intricacies and exploring the interrelationships between suspicio and resolutio. As such it offers a pioneering and comprehensive exploration of Calcidius’ account of the knowability of matter. (shrink)

This is an impressive and important book about perception in Plato’s Timaeus, but most of its readers will probably be researchers who are interested in much broader questions about the dialogue. There is nothing deficient or lacking about this treatment of perception, but this book should be put alongside Thomas Johansen’s Plato’s Natural Philosophy and Sarah Broadie’s Nature and Divinity in the sense that this is, for all intents and purposes, a monograph about the whole Timaeus, even though it is (...) pitched as being focused on perception. There are only a few topics missing, such as the nature of the cosmic receptacle and psychic diseases. Virtually everything else, including the status of Timaeus’ so-called likely story, the generation of the lower gods, and the nature of bone, is discussed at length. (shrink)

In the present paper, I argue that in order to be in a position to understand what the World Soul thinks about, we need first to answer the question of whether the universe perceives and if so, of what it perceives. I shall first (section ) lay out the main reasons for suspecting that the universe has perception and some possible objections against this view. I will then (section ) make a case for my claim that the universe has perception (...) on the basis of my ‘minimalist’ account of perception, which identifies four necessary and jointly sufficient conditions for having an instance of aisthēsis: 1) a body; 2) a soul; 3) affections which cause motion/change in the body and in the soul; 4) the cause of these affections. I will show that the universe composed of a World Body and a World Soul meets all four conditions. On the basis of this, I will claim that one can ascribe (self-) perception to the universe. Finally (section ), I will suggest that the universe perceives the polyhedra of its own body. (shrink)

This book sheds new light on Plato's cosmology in relation to Greek religion by examining the contested distinction between the traditional and cosmic gods. A close reading of the later dialogues shows that the two families of gods are routinely deployed to organise and structure Plato's accounts of the origins of the universe and of humanity and its social institutions, and to illuminate the moral and political ideals of philosophical utopias. Vilius Bartninkas argues that the presence of the two kinds (...) of gods creates a dynamic, yet productive, tension in Plato's thinking which is unmistakable and which is not resolved until the works of his students. Thus the book closes by exploring how the cosmological and religious ideas of Plato's later dialogues resurfaced in the Early Academy and how the debates initiated there ultimately led to the collapse of this theological distinction. (shrink)

I argue that Plato thinks that a sunaition is a mere tool used by a soul (or by the cosmic nous) to promote an intended outcome. In the first section, I develop the connection between sunaitia and Plato’s teleology. In the second section, I argue that sunaitia belong to Plato’s theory of the soul as a self-mover: specifically, they are those things that are set in motion by the soul in the service of some goal. I also argue against several (...) popular and long-standing interpretations, namely, that sunaitia correspond to Aristotle’s idea of hypothetical necessity, that sunaitia are the ‘how’ in an explanation (whereas the true cause is the ‘why’), and that Plato’s causal views should be read through Aristotle’s fourfold schema. I conclude the article by surveying the history of sunaitia after Plato’s usage. (shrink)

This is an essay on perception and its objects in the Timaeus. Two features of this work are noteworthy. First, the emphasis throughout is on Timaeus' views and not Plato's. Second, I show how broader aspects of Timaeus' cosmology are directly relevant to his philosophy of perception.

The relationship between mind and necessity is one of the major points of difficulty for the interpretation of Plato’s Timaeus. At times Timaeus seems to say the demiurge is omnipotent in his creation, and at other times seems to say he is limited by pre-existing matter. Most interpretations take one of the two sides, but this paper proposes a novel approach to interpreting this issue which resolves the difficulty. This paper suggests that in his speech Timaeus presents two hypothetical models (...) of creation, one with an omnipotent demiurge and one where he is limited by matter, so as to investigate their theoretical and empirical validity. Further, he shows that each model is ultimately an inadequate explanation of the first principles of the cosmos. Timaeus’ speech is therefore properly understood to be aporetic: it leaves its listeners aware of the difficulties inherent in the two models of creation, but without a more viable alternative. (shrink)

The aim of this paper is to provide a new reading of Plato’s precosmos (Ti. 52d2–53c3). More specifically, I shall argue that the precosmos is populated by bodies deriving from random complexes of properties, and that this is the effect of the Receptacle’s full precosmic participation in the Paradigm. This will turn out to be consistent with a robust notion of ‘precosmic generation’ and will reveal why Plato may have sought to refer to this otherwise puzzling scenario: representing the precosmos (...) in this way allows Plato to effectively justify why the Demiurge is responsible only for the goodness and perfection of the universe, and why it is properly the best possible cause. (shrink)

The principles governing elemental composition, variation, and change in Plato’s Timaeus appear to be incompatible, which has led commentators to prioritize some of the principles to the exclusion of others. Call this seeming incompatibility the problem of isomorphic variants. In this paper, I develop the theory of proportionate atomism as a solution to this problem. Proportionate atomism retains the advantages of rival interpretations but allows the principles of material composition, variation, and change to combine into an internally coherent and explanatorily (...) powerful atomic physics.

In our article, we will focus on an analysis of the relationship between man and the cosmos, set against the backdrop of ancient Greek ideas about the origin of the world. On the one hand, we will deal with the images of the creation of the world provided in Greek mythology and the religious tradition associated with it (in particular Hesiod); on the other hand, we will approach the anthropomorphic elements within the framework of philosophical cosmogonies (Plato’s dialogue, the Timaeus). (...) Our aim is to show that Greek philosophical thought was never able to fully relinquish this anthropomorphism but nonetheless it did move away from a purely mythological tradition (as found in Hesiod and the pre-Socratics) and, in some measure towards a more scientific interpretation of the cosmos (as found in Plato).

Cosmological narratives like the creation story in the book of Genesis or the modern Big Bang are popularly understood to be descriptions of how the universe was created. However, cosmologies also say a great deal more. Indeed, the majority of cosmologies, ancient and modern, explore not simply how the world was made but how humans relate to their surrounding environment and the often thin line which separates humans from gods and animals. Combining approaches from classical studies, anthropology, and philosophy, this (...) book studies three competing cosmologies of the early Greek world: Hesiod's Theogony; the Orphic Derveni theogony; and Protagoras' creation myth in Plato's eponymous dialogue. Although all three cosmologies are part of a single mythic tradition and feature a number of similar events and characters, Olaf Almqvist argues they offer very different answers to an ongoing debate on what it is to be human. Engaging closely with the ontological turn in anthropology and in particular with the work of Philippe Descola, this book outlines three key sets of ontological assumptions - analogism, pantheism, and naturalism - found in early Greek literature and explores how these competing ontological assumptions result in contrasting attitudes to rituals such as prayer and sacrifice.

As in the case of other humanists and philosophers of the period, an important aspect of Pico della Mirandola's interpretation of the Platonic Timaeus consists of direct access to the dialogue in its original Greek, which the young man possessed in his personal library. This does not mean that Pico does not also take an interest in the ancient Latin translations of Cicero and Calcidius, both personally and in Ficino's circle. But these are read with the critical distance and the (...) historical and philological rigour of the period. Plato's cosmology, his theory of first principles, of the structure of the cosmos and of human nature, are read by Pico in dialogue, in contrast and in hidden coincidence with the Aristotelian system of the universe, but also alongside the conceptions of the world and of humankind of other Jewish, Christian, Neoplatonic, Arabic, Hermetic and Kabbalistic authors and texts. Demonstrating the confluence of all these systems with biblical revelation is particularly pressing for Pico, who knows himself to be the heir of the Greek and Latin patristic authors. Nevertheless, the pagan philosophical tradition occupies a privileged place in the exegetical lenses of Pico, who has recourse on countless occasions to the Commentary on the Timaeus of Proclus and to the exegeses of Plutarch, Porphyry, Iamblichus, Emperor Julian and Simplicius, not forgetting the allegedly ancient Pythagorean Timaeus of Locri and Ocellus Lucanus. The chapter offers, in addition to an introduction to Pico's figure and oeuvre, an analysis of his reception of the Timaeus and a trilingual edition (Latin-Spanish, Tuscan-Spanish) with some of the central passages of his works.

General introduction to early Greek philosophical exegeses of Plato's Timaeus, from the early Academy to the beginning of the Roman Empire in pagan, Jewish and Christian circles. -/- Introducción general a las primeras exégesis filosóficas del Timeo de Platón, desde la temprana Academia hasta los inicios del Imperio romano en ámbitos paganos, judíos y cristianos de habla griega.

This article 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.

Marsilio Ficino’s view on ensoulment, which can be extrapolated from his critique of natal astrology, relies on the relations of metaphysical proportion between the different levels of life and being which are central to Platonic philosophy. Drawing primarily on Plotinus, Ficino describes the emergence of life in the embryo as a process in which the World Soul is the true agent. For him, the ‘human nature’ that is present in the developing embryo attracts into the mother’s womb the seed of (...) ‘human nature’ which is present in the World Soul’s vegetative power. Once channelled into the womb, the World Soul’s vegetative power animates the embryo’s body. Now endowed with organic life, the embryo becomes irresistibly attractive to the rational soul, which in this way is drawn down to it and becomes embodied. For Ficino, the moment when ‘rational’ ensoulment happens is completely irrelevant to prefiguring one’s life path, contrary to what was claimed by natal astrology. Nevertheless, it leaves an important mark on one’s physio-psychological makeup. (shrink)

Analogies between the human and the cosmos run throughout Plato’s Timaeus. Timaeus claims that the cosmos came to be as mind’s “persuasion of necessity.” This paper argues that an anthropological equivalent to this “persuasion” can be found in Timaeus’ suggestive account of the human liver. Mediating between intellect and desire, the organ shows the problem of mind and necessity reflected in the human soul.

Plato used mathematics extensively in his account of the cosmos in the Timaeus, but as he did not use equations, but did use geometry, harmony and according to some, numerology, it has not been clear how or to what effect he used mathematics. This paper argues that the relationship between mathematics and cosmology is not atemporally evident and that Plato’s use of mathematics was an open and rational possibility in his context, though that sort of use of mathematics has subsequently (...) been superseded as science has progressed. I argue that there is a philosophically and historically meaningful space between ‘primitive’ or unreflective uses of mathematics and the modern conception of how mathematics relates to cosmology. Plato’s use of mathematics in the Timaeus enabled the cosmos to be as good as it could be, allowed the demiurge a rational choice and allowed Timaeus to give an account of the cosmos. I also argue that within this space it is both meaningful and important to differentiate between Pythagorean and Platonic uses of number and that we need to reject the idea of ‘Pythagorean/platonic number mysticism’. Plato’s use of number in the Timaeus was not mystical even though it does not match modern usage. (shrink)

Plato’s Timaeus reveals a cosmos governed by Necessity and Intellect; commentators have debated the relationship between them. Non-literalists hold that the demiurge, having carte blanche in taming Necessity, is omnipotent. But this omnipotence, alongside the attributes of benevolence and omniscience, creates problems when non-literalists address the problem of evil. We take the demiurge rather as limited by Necessity. This position is supported by episodes within the text, and by its larger consonance with Plato’s philosophy of evil and responsibility. By recognizing (...) the analogy between man and demiurge, the literal reading provides a moral component that its non-literal counterpart lacks. (shrink)

Two of Plato’s dialogues, the Parmenides and the Timaeus, deal explicitly with the relationship between being and time. The former builds on the assumption that whatever is must be temporal, while the latter makes being and time mutually exclusive. This paper begins by examining how the argument develops in the Parmenides, specifically in the corresponding sections 140e1-142a1 and 151e3-155e3 of the first and the second deductions of the dialectical exercise, as well as in the corollary to the second deduction at (...) 155e4-157b5. It then compares this argument with the account of time given in Timaeus 37e6-39e2, which alludes to the account given in the Parmenides. In stressing the incompatibility of these two accounts, it highlights a remarkable feature they both share. Parmenides’ argument starts from the assumption that whatever is in time must be present, past or future, whether a process or a state resulting from a process. As he advances further in the game of Zenonian antilogies, however, he reduces the dimension of the present to a mere ‘now’, conceived of as a ‘stop’ in the process of becoming. In the corollary, he eventually removes the present from time the ‘instant’ in which a change between two mutually exclusive processes or states occurs. Timaeus, for his part, immediately rules out that the present is a temporal dimension, by restricting temporality to the past and the future. Thus, in both accounts, the present vanishes from time and temporal processes are made dependent on extratemporal conditions. However, Parmenides’ argument points to an extratemporal principle of indeterminacy allowing for change, while, for Timaeus, there are two extratemporal conditions for temporal processes, namely the being of the intelligible Forms, on the one hand, and a pre-cosmic, disorderly becoming in space, on the other.

How does Plotinus interpret the chora in Plato’s Timaeus? For him, Timaeus 48e‑52d deals with matter (hyle). The identification of chora with hyle goes back to Aristotle’s Physics IV.2. Aristotle’s interpretation of Plato’s chora as matter was echoed by Theophrastus and the Stoics and prevailed in Middle‑Platonist, neo‑Pythagorean and early Christian authors. In addition to the identification of chora with hyle, the ancient interpreters of the Timaeus conflated hyle with Plato’s ananke (Tim. 47e‑48a). Plato himself distinguishes between chora and ananke. (...) The latter denotes everything that appears in the “receptacle” prior to the ordering of the world by the demiurge, while chora is another name for the receptacle itself. In Plato, the receptacle accounts for the fact both that there are transient images of intelligible beings and that these images appear to occupy a place, i.e. that they are spatially extended. This is why the receptacle is given its alternative name “ground” (chora) and why it is also called “place” (topos) and “seat” (hedra). Although the receptacle itself cannot be spatially extended in the same way as that which appears “in it”, it is the cause of spatial extension. For Plotinus, two characteristics of matter are of primary importance : lack of size and impassibility. In the treatise II.4.[12].2‑5, he highlights the former, and in III.6[26].7‑19 he elaborates on the latter, while commenting once again on the former. In III.6[26].7‑19, he argues that this conception of matter is in line with how Plato conceives of it in the Timaeus. The “receptacle” cannot be acted upon (paschein) nor can it possess any size (megethos). Only the images of true beings “in” it can. In doing so, however, they make matter appear to “stretch out” alongside themselves. But this is not actually the case, because matter itself has no extension. On one point, however, Plotinus’ account differs from Plato’s. According to Plotinus, not only does matter not possess size, but it is not the cause of size either. The size of the appearances derives from the formulas (logoi) of which these appearances are images. Each formula encompasses within itself the measure of the size that its image will assume : the formula of horse encompasses the size of a particular horse, the formula of human being the size of a particular human being. Plotinus describes in more detail how a formula, in unfolding out of the soul, “stretches out”, thus acquiring size. He also makes a comparison between this process and the way in which formulas in the human soul display images of themselves in our image‑making faculty. He characterises this process as a motion starting from the formula and resulting in its “division” (merismos). This is what makes the image of the formula extended, i.e. divided partes extra partes, when it appears against the invisible background of matter. Since matter neither possesses size nor is the cause of it, it can be called “ground” (chora), “place” (topos) or “seat” (hedra) only in an improper way. (shrink)

The Timaeus is perhaps the most unusual of Plato’s dialogues. In this paper, I attempt to interpret Timaeus’s strange speech, which makes up most of the dialogue. I argue that Timaeus has grasped the grave challenge posed to philosophic reason by men like Hesiod who claim that mysterious gods are the first causes of the world, and therefore one cannot say that there are any true necessities governing this world. If this is true, then philosophy, as the study of nature, (...) which depends on the existence of necessity, would be impossible. Timaeus articulates two serious attempts to meet this challenge by demonstrating the stability and rational comprehensibility of the world from solid first principles: one according to which mind is the cause of all things; another according to which everything comes to be through mindless necessity. But he ultimately suggests that neither of these attempts have been successful, thereby demonstrating the limits of natural science’s ability to meet the religious challenge. Timaeus’s speech also has a rhetorical purpose related to this failure: insofar as he finds himself unable adequately to meet the religious challenge, and yet is still attracted to and finds worthwhile the pursuit of philosophy, he thinks a rhetorical account of the cosmos is necessary to shore up faith in reason for elite and educated young men who find themselves inclined to natural science. The more rhetorical aspects of Timaeus’s speech, and above all his account of the triangles, serve this purpose. (shrink)

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)

The Timaeus is a muthos that attempts to imagine a logos of the cosmos. Like the demiurge, readers are to be mimetic artists, poets, who move constantly between the intelligible essences and their likenesses in the world of appearance, experience, and becoming, occupying a third register that is neither and both. The cosmology of the Timaeus is both a likely story and an allegory of its own failure. It takes place within the nonspace of the khōra, a realm accessible only (...) through bastard reasoning that we can perceive only as if in a dream. The Timaeus is an unfinalizable logos in which each moment of positing is also a moment of irony and interrogation, of simultaneous acceptance and active separation, of choric space. (shrink)

One short passage on what is called the Receptacle in Plato’s Timaeus has been the subject of much controversy since Cherniss presented an alternative reading of it in 1954. In this paper, I criticize an influential argument presented by Zeyl for a traditional reading, and propose a new interpretation which adopts the alternative reading on important sentences of the passage, but is not accompanied by the defects of Cherniss’ interpretation.

In Plato’s Timaeus, two different theories – the Receptacle theory and the geometrical particle theory – are presented to explain change in the natural world. In this paper, I argue that there is tension between the two theories. After examining several possible solutions for this tension, I conclude that Plato does not present it as something ready to be solved within the dialogue but, rather, as something to be understood in a way that maintains both theories. Finally, I also argue (...) that the contrast between the two theories in the Timaeus derives from a similar contrast in the Phaedo. (shrink)

At Tm. 47e, Timaeus steps back from his discussion of what came about through noûs and turns toward an account of what came about through anankê. Broadie, 2012, Nature and Divinity in Plato’s Timaeus, sketches out two routes for the interpretation of this ‘new beginning.’ The ‘metaphysical’ approach uses perceptibles qua imitations of intelligibles in order to glimpse the intelligibles (just as we look at our reflection in a mirror in order to view ourselves). The ‘cosmological’ reading assumes we use (...) the perceptible part of the cosmos in order to come to know the entire cosmos. Broadie openly favors the cosmological reading for understanding the Timeaus as a whole. However, she confines its utility to the Timaeus and does not recommend it for other dialogues. I use Broadie’s ‘cosmological reading’ to better understand what Plato distinguishes as anankê in his second beginning. This sets the stage for my argument that Broadie’s cosmological reading is a promising means for understanding the metaphysics and epistemology of the Forms. By making some comparisons to Sophist (251c–256a), I show that a refined understanding of anankê in the second beginning of the Timaeus clarifies what Plato thinks is involved in coming to know a Form. I argue that a close look at what was available to the Demiurge for cosmic creation by means of noûs yields three distinct ways in which his construction of the cosmos was limited by anankê. Clarifying these three ways in which anankê operates shows that the Demiurge’s manipulation of the foundational elements yields a perceptible world that brings out some potential relationships among Forms while suppressing others. In particular, the Demiurge’s geometricization of the elements leads him to make compromises concerning how Forms can combine in the Receptacle. These choices produce nomological relationships among the Forms with respect to where they can overlap in the Receptacle. This produces the law-like and reliable, but unnecessary, behavior of the perceptible world. I argue that our understanding of these limitations and their translation into where the Receptacle can partake in more than one Form simultaneously, figures importantly in the estimating the potential for human knowledge of the Forms. I question the use of ‘necessity’ as a translation for ‘anankê’ in the Timaeus. (shrink)

Au moment de décrire la fonction des yeux humains, qui sont donnés par les dieux afin que l’on puisse déduire la philosophie et le nombre à partir de la rotation du firmament, Timée interrompt son récit pour développer son explication des mécanismes physiques sous‑jacents à la fois à la vision et à tout type de mouvement et de changement. Il est intéressant de noter que, dans le contexte du Timée dans son ensemble, la chôra ne semble pas indispensable. Par exemple, (...) l’explication de la nécessité impliquant les types corporels de base et leurs isotopes et composés aurait pu s’effectuer assez facilement avec la simple affirmation des quatre solides réguliers, de leurs mouvements réguliers et des deux triangles élémentaires dont ils sont composés. Je soutiens dans cet article que si nous regardons la chôra dans le contexte du récit antérieur du mouvement d’errance des planètes, dont on dit qu’elles encadrent et font ressortir le nombre et l’identité du mouvement des étoiles fixes, et que si nous comparons cela à la décomposition des triangles élémentaires dans le contexte de la vie et de la mort du corps doté d’une âme, nous pourrons discerner la chôra dans le mouvement errant du vieillissement, de l’effondrement et de l’éloignement de la limite normative dans le récit plus large de la vie dans le Timée, tant au niveau biologique que moral de la description. Cette approche permettra de rendre compte non seulement de l’unité de la pensee de Timée, mais aussi du caractère disruptif du tournant remarquable par lequel il introduit la cause errante. (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.

Le démiurge de Platon et l'atome primitif de Lemaître sont deux intuitions inédites, artifices théoriques d'astronomie anti-observationnelle. La genèse de ces artifices remonte à la thématisation présocratique de l'unité cosmique. Platon institutionnalise les Formes intelligibles et platonise les présocratiques. Lemaître, contemporain d'Einstein, est tributaire d'une unité cosmique marquée par la gravitation relativiste, qui disqualifie le système classique ayant, en son temps, déclassé les substances et le mouvement aristotéliciens. La théorisation montre comment Platon fait du démiurge le concept axial de son (...) astronomie géométrique. L'univers est conforme aux normes mathématiques. La perspective dynamique de Lemaître émerge contre le modèle stationnaire d'Einstein/De Sitter, aristotélicien en son fond. Au bout, deux configurations apparaissent : sphérique et homogène, l'univers de Platon repose sur le triangle. L'« âme du monde » en assure la dynamique. D'interprétation quantique, la singularité cosmique de Lemaître développe le modèle d'un univers issu de l'explosion (big bang) d'un atome primitif : l'isotope du neutron. (shrink)

In the present article, we consider the question of the primary elements in Plato’s Timaeus, the components of the whole universe reduced, by an extraordinarily elegant construction, to two right triangles. But how does he reconcile such a model with the infinite diversity of the universe? A large part of this study is devoted to Cornford’s explanation in his commentary of the Timaeus and its shortcomings, in order to finally propose a revised one, which we think to be entirely consistent (...) with Plato’s text. This analysis is an essential step for the understanding of the connection between the sensible world and the mathematical principles that underlies Timaeus’ cosmological account. (shrink)

Recent scholarship has followed Glenn Morrow in seeking to understand Plato’s politics in light of his cosmology. This essay takes a different tack and interprets the theology and cosmology of the Laws as an outgrowth of the Athenian Stranger’s conversation with Kleinias, which focuses on politics and warfare. In that sense the arguments of Book 10 are closely tied to the context of the dialogue. The Athenian Stranger’s religious ideology is not designed to be permanent or universally applicable. Rather, it (...) is intended for an audience that finds itself immersed in an unhealthy world of motion, disorder, and antagonism. (shrink)

Readers of Plato since antiquity have generally taken Socrates’ intellectual autobiography in the Phaedo as a signal of his turn away from the study of natural philosophy. They have turned instead to characters such as Timaeus for evidence of Plato’s pursuit of physics. This article argues that Plato’s Socrates himself developed a philosophy of nature in his criticism of Anaxagoras and his subsequent philosophic pursuits. Socrates’ autobiography places the study of nature in a foundational position within the development of his (...) philosophic method. In the Apology, Socrates further elaborated his investigation into nature through his understanding of theology. Finally, in the Phaedrus, Socrates connects the study of nature with the study of rhetoric as tools for virtue. Therefore, Plato’s Socrates does not reject or abandon physics, as has often been suggested, but rather, he incorporates it into his own philosophic project and challenges its practitioners to connect their own inquiries with human affairs.

At Plato’s Phaedrus 270c, Socrates asks whether one can know souls without knowing ‘the whole.’ Phaedrus answers that ‘according to Hippocrates’ the same demand on knowing the whole applies to bodies. What parallel is intended between soul-knowledge and body-knowledge and which medical passages illustrate the analogy have been much debated. Three dominant interpretations read ‘the whole’ as respectively (1) environment, (2) kosmos, and (3) individual soul or body; and adduce supporting Hippocratic passages. But none of these interpretations accounts for the (...) Phaedrus’ rhetorical method. A better reading sees the whole as the genos ‘soul,’ as the Phaedrus’ taxonomies divide that genus. (shrink)

Plato argued that knowledge of human nature can be reached through dialogue and dialectical method in accordance with the Socratic heritage. In his philosophy, man can be defined as being capable of rationally answering a rational question. By giving rational answers to himself and others, human also becomes a moral subject. In Plato's philosophy, we see a clear program based on human nature. Issues related to human nature are discussed in the process of applying Plato's theory of ideas to the (...) field of morality, art, politics and education. What emerges in practice, for example, right and fair behavior is a manifestation of the principle of truth and justice. According to Plato, man reflects the character of the state he lives in. To understand a person, it is necessary to consider the society in which he lives. The state is not an institution that people come together and establish with their own will, but an organism, a whole. According to Plato, in order to grasp the true meaning of human society and to arrange it properly, one must first comprehend the astronomical cosmos. Because, knowing the meaning of the concepts of harmony and order is possible only by understanding the astronomical cosmos, which is the expression of an eternal order. While studying the astronomical cosmos, a man comes to the idea of harmony and order itself. Indeed, the infinite canonical and harmonious movements of the stars in this pre-eternal order on their perennials lead to the concept of law itself. People who admire this harmony and order in the sky want to realize a model of it on earth. He concludes that the laws that will rule over the human world must be continuous and compatible, just like the laws in the world of stars. Thus, the state must be an earthly model of the astronomical cosmos. If a person lives in the state, he should realize this harmony and order in the state in his own spirit. (shrink)

In this essay, I argue that the ordering of the speeches in Plato’s Timaeus indicates two things. First, each speech represents one of the three genera or principles Timaeus discusses. Socrates’ summary represents the forms, Critias’ Atlantis story embodies Becoming, and Timaeus’ cosmology serves as χώρα. Second, Timaeus responds to the other speakers in the order in which they were presented before beginning again with χώρα. Once Timaeus introduces χώρα, one of his tasks is laying the groundwork for Critias’ war (...) story. My reading would prioritize the moral and political underpinnings of Timaeus’ cosmology over the more scientific or metaphysical interpretations of the text. (shrink)

Chez les interprètes récents du Timée de Platon, le terme « téléologie », inventé au xviiie siècle, a pris une place déterminante. Mais l’usage de ce terme trahit une interprétation aristotélicienne de la figure du démiurge qu’il s’agit d’assimiler au premier moteur, dans le contexte de la cause finale. On s’interrogera ici sur l’origine de ce terme, et sur la pertinence de son usage pour comprendre le rôle que joue le démiurge dans le Timée.

The Platonic chora, as the third, intermediating term, has been left in a state of virtual dereliction in the West. Its ternary logic transmutes oppositional logics of binarity, including the oppositions of interior and exterior, psyche and cosmos, human and divine. In this article I analyse the mytho-philosophical trajectory of the chora from Plato’s Timaeus, and Diotimaic love found in Plato’s Symposium. I argue that both the disruptive force of Diotimaic love, and the subversive chora with its ‘bastard reasoning’1 are (...) indicative of Plato’s efforts to resolve an internalized conflict which mirrored a larger conflict found in his cultural epoch, a time in which abstracted self-consciousness was on the horizon and chthonic-participatory consciousness was receding. In membering the chora I find a fecund space-time, an enabling field, for human participatory becoming-with the cosmos. (shrink)

A far-reaching reinterpretation of Plato’s Timaeus and its engagement with time, eternity, body, and soul that in its original French edition profoundly influenced Derrida The Tomb of the Artisan God provides a radical rereading of Timaeus, Plato’s metaphysical text on time, eternity, and the relationship between soul and body. First published in French in 1995, the original edition of Serge Margel’s book included an extensive introductory essay by Jacques Derrida, who drew on Margel’s insights in developing his own concepts of (...) time, the promise, the world, and khōra. Now available in English with a new preface by Margel, this engagement with Platonic thought proceeds from two questions that span the history of philosophy: What is time? What is the body? Margel’s twinned interrogation centers around Plato’s concept of the demiurge (divine artisan or craftsman): its body, its anthropomorphic attributes, its productive capacities and regulatory functions in the ordering/organization/assembling of the world. He posits that this paradoxical figure is not merely a cosmological metaphor for the living body but also the site of its destruction, dissolution, and disappearance. Torn between the finite and the infinite, being and becoming, the concept of demiurge also poses metaphysical questions about time, time before time, and the end of time. The ontological status of the demiurge’s body, Margel argues, would become increasingly decisive in the history of philosophy, particularly in Christianity and the dogma of incarnation. (shrink)
