Plato: Timaeus

I argue that Plato has a full-blown environmental philosophy. In the first section, I argue that Plato defended vegetarianism and that he did not see animals as existing for the sake of human beings. In this respect, animals differ from plants: plants do exist for our sake, but animals do not. Then, I argue that Plato is committed to important parts of today's ecocentrist environmental-ethical theories that hold up ecosystems as intrinsically valuable. I also argue that Plato believes that the (...) Earth is worthy of our veneration and praise. I conclude by arguing that Plato's environmental philosophy does have some important limitations.

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)

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)

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)

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.

O problema deste paper constitui-se a partir da seguinte pergunta: seria Platão um plagiador dos pitagóricos? A suspeita nasce de uma tradição já antiga pela qual Platão é acusado de ter plagiado uma suposta obra atualmente perdida de Filolau de Crotona. Tomou-se, então, como objeto de análise, a obra Timeu, a fim de verificar a existência de trechos que poderiam sugerir um plágio por parte de Platão. Para tanto, realizou-se um levantamento das principais teorias “pitagóricas” identificáveis no Timeu, a partir (...) de uma revisão da história da crítica. Concluiu-se que, inegavelmente, há referência implícita ao pitagorismo na obra, a qual, entretanto, não configura propriamente um plágio, mas, sim, pode ser melhor considerada como uma influência pitagórica. Efetivamente, Platão acaba por transpor diversas teorias “pitagóricas” – bem como de outros filósofos pré-socráticos – para seus próprios interesses filosóficos. (shrink)

Scientific observation has led to the discovery of recurring patterns in nature. Symmetry is the property of an object showing regularity in parts on a plane or around an axis. There are several types of symmetries observed in the natural world and the most common are mirror symmetry, radial symmetry, and translational symmetry. Symmetries can be continuous or discrete. A discrete symmetry is a symmetry that describes non-continuous changes in an object. A continuous symmetry is a repetition of an object (...) an infinite number of times. A consequence of continuous symmetry is the existence of conservation laws. A natural system with discrete and continuous symmetries displays several physical properties, such as the existence of long-range order. Geometric shapes exhibit symmetry as mirror reflections of each other. Symmetry in nature has been a model of beauty since the beginning of civilization. Since the earliest times, nature itself has manifestly been a model, evincing regularity in sundry forms and occurrences–from minerals and plants to the anatomy of living beings, to the regularly recurring stellar constellations. For Ancient Greek philosophers, proportion, symmetry, and harmony, were the basics to determine whether something is beautiful or not. Ancient Greek philosophers were known for bringing logic and rational thinking to phenomena that were previously explained by mythology and Gods. They observed the natural world around them and used their knowledge to answer questions about the proportion in observable objects and the origin of Earth. The Greek words _summetria_ and _summetros_ appear frequently in the Timaeus, defined as parts with each other and with the whole. Plato has a very rough concept of symmetry, and when he uses “beauty” to characterize the so-called Platonic Solids in the Timaeus, he seems to be emphasizing their regularity and indirectly their symmetry. Plato believes the four elements (earth, air, fire, water) have been constructed by the Demiurge, or a divine craftsman who appoints order in an otherwise chaotic universe. Minerals are representative examples of beauty, order, and symmetry in inorganic materials. Well-formed minerals (crystals) are a collection of equivalent faces related by symmetry. The goal of this paper is to relate the perspective of symmetry in ancient Greek philosophy with the modern scientific evidence of the geometric description of crystal structures. The five Platonic solids are ideal models of geometrical patterns that occur throughout the world of minerals. In this paper, minerals serve as a model of connecting the symmetry theory in Plato’s philosophy and modern advances in mineralogy. (shrink)

The prevailing narrative in the history of science maintains that the ancient Greeks did not have a concept of a ‘law of nature’. This paper overturns that narrative and shows that some ancient Greek philosophers did have an idea of laws of nature and, moreover, they referred to them as ‘laws of nature’. This paper analyzes specific examples of laws of nature in texts by Plato, Aristotle, Philo of Alexandria, Nicomachus of Gerasa, and Galen. These examples emerged out of the (...) closely intertwined Platonic and Pythagorean traditions, and these philosophers’ texts make reference to laws of nature when describing arithmetical methods, arithmological doctrines, or medical theories. Nicomachus’ laws of nature are especially noteworthy, because they have features that historians look for in the search for the origin of the modern concept of laws of nature. Nicomachus’ laws of nature are mathematical, universal, and necessary. This paper raises the possibility that the ancient Platonic and Pythagorean traditions influenced the subsequent development of the idea of laws of nature in medieval and early modern Europe, including the conception of laws of nature deployed by Johannes Kepler and Isaac Newton.

I argue that in the Phaedo, Plato maintains that the soul is located in space and is capable of locomotion and of interacting with the body through contact. Numerous interpreters have dismissed these claims as merely metaphorical, since they assume that as an incorporeal substance, the soul cannot possess spatial attributes. But careful examination of how Plato conceives of the body throughout his corpus reveals that he does not distinguish it from the soul in terms of spatiality. Furthermore, assigning spatial (...) attributes to the soul plays an important role in Plato’s account of the relation of body and soul. (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)

In this article, I make the case for the continued relevance of Plato’s Timaeus. I begin by sketching Allan Bloom’s picture of the natural sciences today in The Closing of the American Mind, according to which the natural sciences are, objectionably, increasingly specialized and have ejected humans qua humans from their purview. I argue that Plato’s Timaeus, despite the falsity of virtually all of its scientific claims, provides a model for how we can pursue scientific questions in a comprehensive way (...) that stresses their connections to other disciplines, including the humanities, and that puts humanity qua humanity back in the picture. I then argue that being led by Plato’s philosophy to return humanity conceptually to the natural world can improve our thinking regarding climate change and other important environmental crises. (shrink)

Plato's moral realism rests on the Idea of the Good, the unhypothetical first principle of all. It is this, as Plato says, that makes just things useful and beneficial. That Plato makes the first principle of all the Idea of the Good sets his approach apart from that of virtually every other philosopher. This fact has been occluded by later Christian Platonists who tried to identify the Good with the God of scripture. But for Plato, theology, though important, is subordinate (...) to metaphysics. For this reason, ethics is independent of theology and attached to metaphysics. This book challenges many contemporary accounts of Plato's ethics that start with the so-called Socratic paradoxes and attempt to construct a psychology of action or moral psychology that makes these paradoxes defensible. Rather, Lloyd Gerson argues that Plato at least never thought that moral realism was defensible outside of a metaphysical framework. (shrink)

This paper re-constructs Plato's ‘philosophy of geometry’ by arguing that he uses a geometrical method of hypothesis in his account of the cosmos’ generation in the Timaeus. Commentators on Plato's philosophy of mathematics often start from Aristotle's report in the Metaphysics that Plato admitted the existence of mathematical objects in-between ( metaxu) Forms and sensible particulars ( Meta. 1.6, 987b14–18). I argue, however, that Plato's interest in mathematics was centred on its methodological usefulness for philosophical inquiry, rather than on questions (...) of mathematical ontology. My key passage of interest is Timaeus’ account of the generation of the primary bodies in the cosmos, i.e. fire, air, water and earth ( Tim. 48b–c, 53b–56c). Timaeus explains the primary bodies’ origin by hypothesising two right-angled triangles as their starting-point ( arkhê) and describing their individual geometrical constitution. This hypothetical operation recalls the hypothetical method which Socrates introduces in the Meno (86e–87b), as well as the use of hypotheses by mathematicians which is described in the Republic (510b–c). Throughout the passage, Timaeus is focussed on explicating the bodies in terms of their formal structure, without however considering the ontological status of the triangles in relation to the physical world.

This paper approaches the Critias straightforwardly as a work of political philosophy but gives greater attention to Athens’ opponent, Atlantis, whose founding, political organization, and eventual decline each offer important lessons about the aims of legislation and political life. I begin by comparing the foundation of the two cities as presented in Critias’ myth, with a special focus on the role of divine persuasion (I). I then describe the political organization of Athens and Atlantis, showing how they reflect the different (...) ways in which their founding gods exercised divine persuasion (II). Next, I focus on the decline of Atlantis and the causes behind it (III). Finally (IV), I discuss the lessons that I think can be gathered from the foregoing sections and show how the themes that emerge from the comparison of the two cities anticipate their more extensive exploration in the Laws.

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)

In this paper I focus on Proclus’ concept of the instrumental cause in his commentary on the Timaeus (In Tim.). Unlike earlier Neoplatonists who do not make much use of this type of causality, Proclus relates the instrumental cause to the hypostasis of nature (φύσις). The Demiurge uses nature as an instrument in his ordering and creation of the cosmos. How does Proclus arrive at this understanding of nature? I argue that the definition of nature as an instrumental cause is (...) in part based on his critical reception of Aristotle who identifies nature with the formal, efficient, and/or final cause. That is, Proclus did not develop his views on the causality of nature only by looking at the Timaeus (and other Platonic sources), but also by engaging with Aristotle’s rich – and, to a certain extent, authoritative – reflections on this issue.

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)

In this paper I first address what I consider a central issue in the account of perception in Plato’s Timaeus, namely, how the pathemata pass through the body to reach the soul, and thus become aistheseis. My point in Section 1 is that in tackling this issue Plato aims to provide a firm physiological basis to the notion of perception that starts to emerge in the Theaetetus and the Philebus and is crucial to the late development of his theory of (...) cognition. In the ensuing section I try to put the account of perception in the Timaeus into a historical perspective, aiming to highlight two points: a) Plato’s description of the way in which sensible impressions “travel” inside the body and interact with its parts and other constituents is largely indebted to previous theories, such as those we find, for example, in Empedocles and a few Hippocratic writers; b) The leading role in this story (where internal air plays a significant supporting role) is played by blood flowing through the vascular system and thus performing a crucial cognitive function. Moreover, emphasizing the role of blood as well as analyzing the elaborate way in which perceptions are transmitted through the body to the soul proves vital to appreciate (in Section 3) the cognitive status of the lower parts of the soul (which are more involved in perception) and their relation to reason. Overall, the paper adds further elements to our understanding of Plato’s embodied approach to cognition. I had already written (and submitted) this article when Johansen (2021) was published. The latter’s approach to the role of blood in Plato’s physiology of knowledge in the Timaeus converges in part with mine (as I was pleased to find out), partly due to our overlapping sources and bibliography.

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.

Plato's Timaeus is unique in Greek Antiquity for presenting the creation of the world as the work of a divine demiurge. The maker bestows order on sensible things and imitates the world of the intellect by using the Forms as models. While the creation-myth of the Timaeus seems unparalleled, this book argues that it is not the first of Plato's dialogues to use artistic language to articulate the relationship of the objects of the material world to the world of the (...) intellect. The book adopts an interpretative angle that is sensitive to the visual and art-historical developments of Classical Athens to argue that sculpture, revolutionized by the advent of the lost-wax technique for the production of bronze statues, lies at the heart of Plato's conception of the relation of the human soul and body to the Forms. It shows that, despite the severe criticism of mimēsis in the Republic, Plato's use of artistic language rests on a positive model of mimēsis. Plato was in fact engaged in a constructive dialogue with material culture and he found in the technical processes and the cultural semantics of sculpture and of the art of weaving a valuable way to conceptualise and communicate complex ideas about humans' relation to the Forms.

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).

That philosophy and medicine provide complementary forms of knowledge of the same subject is attested several times, by many authors, in various ways. For examp.

This chapter is about the movement of sunlight and the concept of time in Timaeus’ cosmology in Plato’s Timaeus. It argues for three connected theses: (i) that light is a grounding principle of his account; (ii) that Timaeus puts forward a proposal for the calculation of a cosmic calendar, i.e., the counting of time according to the movement of sunlight throughout the whole world; and (iii) that he understands time (chronos) as the movement of all heavenly bodies relative to the (...) motion of light streaming from the sun.

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.

In Plato’s eponymous dialogue, Timaeus, the main character presents the universe as an (almost) perfect sphere filled by tiny, invisible particles having the form of four regular polyhedrons. At first glance, such a construction may seem close to an atomistic theory. However, one does not find any text in Antiquity that links Timaeus’ cosmology to the atomists, while Aristotle opposes clearly Plato to the latter. Nevertheless, Plato is commonly presented in contemporary literature as some sort of atomist, sometimes as supporting (...) a form of so-called ‘mathematical atomism’. However, the term ‘atomism’ is rarely defined when applied to Plato. Since it covers many different theories, it seems that this term has almost as different meanings as different authors. The purpose of this article is to consider whether it is correct to connect Timaeus’ cosmology to some kind of ‘atomism’, however this term may be understood. Its purpose is double: to obtain a better understanding of the cosmology of the Timaeus, and to consider the different modern ‘atomistic’ interpretations of this cosmology. In short, we would like to show that such a claim, in any form whatsoever, is misleading, an impediment to the understanding of the dialogue, and more generally of Plato’s philosophy. (shrink)

Cicero’sTimaeuslegitimately stands as the first Latin exegesis of the Platonic dialogue. I shall deal with the interpretation of §§19–21, a passage that departs significantly from the Greek text in several respects. The aim of this paper is to explore the role Aristotelianism might have played in Cicero’sTimaeus. Among the points that support such an analysis is the mention of the Peripatetic Cratippus in the prologue. The interpretative scenario I suggest considers both Cratippus’ role and Antiochus’s philosophical system with its agreement (...) between Platonism and Aristotelianism. (shrink)

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)

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.

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.

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.

My dissertation is a reading of Plato’s Timaeus that centers sexual difference and in particular femininity. I analyze the role of sexual difference in the framing of the dialogue as well as its accounts of body in the first and second discourse and its account of health in the third discourse. I argue that sexual difference, and, in particular, sexual reproduction, serves as a guiding paradigm of Timaeus’ entire project. I argue in each part of my dissertation that various aspects (...) of the Timaeus depend on a certain notion of sexual difference—even aspects which are seemingly causally prior to the issue of sexual difference (e.g., the nature of cause itself, structure). The dissertation consists of three parts. In the first part of my dissertation, I give a new reading of the myth of the origin of women at the end of the Timaeus and bring it into conversation with the dialogue’s opening in order to give an interpretation of the dialogue’s framing. I analyze the concept of sexual difference presented in this myth and argue that its philosophical richness has been overlooked, with many considering it to be either a joke or a sexist account. Focusing on Timaeus’s account of the woman’s relationship with her womb, I argue that womanhood in this myth is constituted by features that are elsewhere characterized as essentially philosophical (e.g., collaboration, making room, recognizing the complex structure of things, and nurture). In the second part of my dissertation, I introduce the two paradigms for the origin and composition of the cosmos in the Timaeus: the first discourse’s craft paradigm that construes the cosmos as a crafted artifact, and the second discourse’s genetic paradigm that construes the cosmos as a birthed organism. I am especially concerned with each discourse’s account of body. Here, I argue that the second discourse’s genetic paradigm is a significant revision of the first discourse’s craft paradigm. While some scholars have found that Timaeus’s insights in the second discourse are a further development of the groundwork he lays in the first discourse, I argue that the genetic paradigm’s focus on femininity and the mutual collaboration of masculine and feminine capacities is incompatible with the craft paradigm’s androcentrism. Finally, in the third part of my dissertation, I analyze the way that the Timaeus centers women’s bodies in its account of health in body and soul. Here, I argue that the Timaeus characterizes health by drawing on ideas about women’s bodies that are framed as symptoms of feminine disease in the Hippocratic texts (e.g., disequilibrium, flux, and porosity). Taken together, the three articles of my dissertation constitute a reading of the role of sexual difference in each part of the Timaeus. (shrink)

This paper aims to consider the specific excerpts in which Plato’s Timaeus was interpreted by the philosopher and Kabbalist Judah Abravanel, also known as Leo the Hebrew in his major work, the Dialogues of Love. From his experience of solitude lived while in exile in Italy, the Portuguese Jew composes a work written in a structure of double meanings, esoteric and exoteric, through which he interacts with the Neoplatonic Renaissance community of his time while communicating with the Kabbalistic tradition from (...) which he descended as a Sephardic. Interpreting Timaeus in the light of his ancestral cosmogony, Leo the Hebrew wants to prove that Plato was initiated into the teachings of Moses and, therefore, must be included as a Kabbalist.

Following the traces of some references to pre-existing matter in the Septuagint, the article analyses the interpretation of Gen 1, 2a in Philo of Alexandria’s De opificio mundi with a focus on his omission of the ἀκατασκεύαστος character of the earth. Philo’s interpretation is closely linked to his conception of emptiness and to his pioneering defence of a creation ex nihilo. In his cosmology, which is articulated as a dual interpretation of the Genesis and Plato’s Timaeus, the matter plays an (...) essential role. Philo justifies its existence on Aristotelian-Stoic grounds, highlighting the process of gradual refinement whereby matter passes from being a rough ὕλη to being an elaborate type of οὐσία. (shrink)

Parmi les difficultés bien connues du Timée compte celle touchant au rôle problématique d’éros dans la cosmologie que Platon met dans la bouche de Timée. Dans son exposé cosmologique, Timée rend compte de deux inflexions différentes d’éros – sexuelle et philosophique –, mais il n’explique pas comment ces deux inflexions sont censées coopérer pour rendre possible la vie la meilleure qui soit : la vie philosophique. Il se trouve que l’imprécision du « discours érotique » de Timée ainsi que son (...) incapacité à rendre compte des conditions de possibilité de l’activité philosophique dans le cosmos qu’il dépeint font surgir la question de l’interprétation du dialogue dans son ensemble. Sans réaliser lui-même cette interprétation, notre article vise à lui en fournir l’éventuelle matière. (shrink)

Aristotle does not uniquely specify, much less define, eudaimonia in the EE’s ergon argument. He concludes simply that eudaimonia belongs to a certain kind. That Aristotle claims to have offered a horos of eudaimonia does not show that he has uniquely specified eudaimonia. This interpretation has implications for our understanding of Aristotle’s Eudemian account of eudaimonia; of Eudemian methodology; and of his use of ergon argument more generally.

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)
