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.

In this article I argue that "Timaeus" 48e-52d, the passage in which Plato introduces the receptacle into his ontology, Contains the material for a satisfactory response to the third man argument. Plato's use of "this" and "such" to distinguish the receptacle, Becoming, And the forms clarifies the nature of his ontology and indicates that the forms are not, In general, self-predicative. This result removes one argument against regarding the "Timaeus" as a late dialogue.

Now with extra footnotes, by editorial demand! Final version accepted by Oxford Studies in Ancient Philosophy. -/- This essay consists in a trick and a potential insight. The trick consists in a minimalist interpretation of color mixture. The account of color mixture is minimalist in the sense that, given certain background assumptions, there is no more to Timaeus’ account of color mixture than the list of the chromatic pathēmata and the list of how these combine to elicit perceptions of (...) all the colors. The only potential controversial elements of the minimalist interpretation are the relevant background assumptions and the interpretation of the chromatic pathēmata. The potential insight concerns a motive that Plato, in the guise of Timaeus, may have for presenting an account of color mixture. Specifically, I shall argue that on the minimalist interpretation, Plato may be read as reconciling the Democritrean four color scheme with an older tradi- tion where white and black are the fundamental chromatic opposition. As we shall see, this bears on the interpretation of the chromatic pathēmata. (shrink)

A study of the significance of Plato's resumption of the simile of model and likeness in the Timaeus, with attention to the place of the Timaeus in the "longer way" that Plato has Socrates announce in the Republic. The reader embarked on the "longer way," I argue, will find in the accounts of the elements and of the kinds of animals unannounced but detailed exhibitions of the "god-given" method of dialectic that Plato has Socrates announce in the Philebus.

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.

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)

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)

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. (shrink)

The third part of the Timaeus, where the account is focused on the cooperation of reason and necessity, has received far less attention than the opening two sections. Particularly, the description of irrigation, digestion and respiration constitutes a challenging passage that has been conspicuously overlooked by scholarly research. Virtually the only modern explanation for the passage was devised by Cornford, and despite several inaccuracies it has been unanimously accepted by all commentators. This paper will challenge Cornford’s interpretation, and use (...) some modern biological concepts to provide an alternative approach to the passage more compatible with an actual human body.

This essay undertakes a reexamination of the notion of the receptacle/chōra in Plato's Timaeus, asking what its value may be to feminists seeking to understand the topology of the feminine in Western philosophy. As the source of cosmic motion as well as a restless figurality, labile and polyvocal, the receptacle/chōra offers a fecund zone of destabilization that allows for an immanent critique of ancient metaphysics. Engaging with Derridean, Irigarayan, and Kristevan analyses, Bianchi explores whether receptacle/chōra can exceed its reduction (...) to the maternal-feminine, and remain answerable to contemporary theoretical concerns.

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.

The Intelligible Living Thing, posited as the model of our visible and tangible universe in Plato’s Timaeus, is often taken for a richly structured whole, which is not a simple sum of its four major parts. This assumption seems unwarranted – most specifically, the dialogue contains no hint at any complex intelligible blue print of the world as a teleologically arranged whole, whose goodness is irreducible to the well-being and individual perfection of its parts. To construe the rich structure (...) of the world is necessary insofar as the Demiurge creates material likenesses of the austere immaterial species. While the life forms included in our universe conform to their intelligible paradigms, this is not, strictly speaking, true about the considerations guiding the Demiurgic activity which gives rise to the universe itself, whose goodness is also to be measured by comparing it to the disordered pre-cosmic matter. The paper discusses several implications of this austere interpretation of the model and its role in creation. It suggests that the Forms that compose the model should be understood as abstract particulars rather than universals, and critically discusses the relation of Timaeus’ account to the so-called Principle of Plenitude.

In the present volume Proclus comments on the creation of the body of the universe in Plato's Timaeus.

In the tripartite psychology of the Republic, Plato characterizes the “spirited” part of the soul as the “ally of reason”: like the auxiliaries of the just city, whose distinctive job is to support the policies and judgments passed down by the rulers, spirit’s distinctive “job” in the soul is to support and defend the practical decisions and commands of the reasoning part. This is to include not only defense against external enemies who might interfere with those commands, but also, and (...) most importantly, defense against unruly appetites within the individual’s own soul.1 Spirit, according to this picture, is by nature reason’s faithful auxiliary in the soul, while appetite is always a potential enemy to be watched ..

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)

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.

Plato’s Timaeus gives an account of the creation of the world and of human race. The text suggests that there was a first generation of human beings, and that they were all men. The paper raises difficulties for this traditional view, and considers an alternative, suggested in more recent literature, according to which humans of the first generation were sexually undifferentiated. The paper raises difficulties for the alternative view as well, and examines the third possibility, advocated by some ancient (...) as well as modern interpreters, according to which there were no first humans, strictly speaking. Although the latter view avoids the pitfalls of the former two views, it crucially rests on a metaphorical reading of the creation story in the Timaeus. (shrink)

Proclus' commentary on Plato's dialogue Timaeus is arguably the most important commentary on a text of Plato, offering unparalleled insights into eight centuries of Platonic interpretation. It has had an enormous influence on subsequent Plato scholarship. This edition offers the first new English translation of the work for nearly two centuries, building on significant recent advances in scholarship on Neoplatonic commentators. It provides an invaluable record of early interpretations of Plato's dialogue, while also presenting Proclus' own views on the (...) meaning and significance of Platonic philosophy. The present volume, the fifth in the edition, presents Proclus' commentary on the Timaeus, dealing with Proclus' account of static and flowing time; we see Proclus situating Plato's account of the motions of the stars and planets in relation to the astronomical theories of his day. The volume includes a substantial introduction, as well as notes that will shed new light on the text. (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 volume Proclus describes the 'creation' of the soul that animates the entire universe. This is not a literal creation, for Proclus argues that Plato means only to convey the eternal dependence of the World Soul upon higher causes. In his exegesis of Plato's text, Proclus addresses a range of issues in Pythagorean harmonic theory, as well as questions about the way in which the World Soul knows both forms and the visible reality that comprises its body. This (...) part of Proclus' Commentary is particularly responsive to the interpretive tradition that precedes it. As a result, this volume is especially significant for the study of the Platonic tradition from the earliest commentators onwards. (shrink)

Today, dignity recognized as a fundamental value across legal systems is equal, inherent and inalienable, inviolable, is the source of human rights and is essential for its subject to be recognized as an autotelic entity (an end in itself) that cannot be treated as an object. The analysis of the extract from Plato’s Demiurge’s speech in Timaeus reveals that Plato developed a reflection on something that determines the qualitative difference between certain beings and the world of things, and that (...) forms the basis for the special treatment of these beings, which the modern language can reasonably describe as dignity. The attributes of that dignity seem to overlap with the nature of dignity as we know today. What is more, Plato proposes a response to the question of what dignity is like but also to the question of what dignity is. It is the existential perfection, established in a perfect way of existence based on a specific internal unity of being. As the existential perfection, it covers the entire being along with all its features; it is inseparable from being (inherent and inalienable) – without it, it cannot exist. It is primordial to the particular features and independent of their acquisition or loss. Plato’s approach allows, based on the approach to dignity, the formulation of proposals aligned with today’s personalistic standards prescribing that persons be treated as ends in themselves and prohibiting the treatment of persons like objects.

In this paper I contend that the 'superfluity' of triangles is only apparent; all those specified are indeed required for the smallest sub-units, so long as the symmetry of the final body to be constructed is taken into account at earlier stages.

In the Timaeus, Plato tells the story of a divine craftsman who, using the world of intelligibles as a model, produces a living and orderly universe from the pre-existing physical elements. The Demiurge in the cosmological narrative has at various times been identified by interpreters of Plato with the model, the product, or even simultaneously both. I intend to argue that there is a strong basis for Plato’s cosmology to be structurally triadic, that is, between a distinct model, cause, (...) and product. As such, the Demiurge, identified with the cause, can be interpreted as ontologically distinct from his product, the World-soul, as well as the model, the Forms. Thus, the Demiurge must be Sui Generis, ontologically distinct from model as well as product. (shrink)

In this paper the Platonic concepts of Goodness, Belief and Will as they appear in the passage 29d–30a of the Timeaus, are examined . The main intention is, through this examination, to explore whether –and, if yes, why- these notions constitute essential elements of Plato’s theology.

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.

Following the structuring hints given by Plato in his Timaeus you find, that the dialogue – actually Timaeus' lecture – falls in two parts, not in three as Cornford, Brisson and others suggest. The main division follows the two invocations of the gods (27c, 48d). The first part presents the world in its noetic form, poetically described as the work of the demiurg. Timaeus opens this part giving first his premises in the form of an introduction, which (...) lead his presentation. At the end of this part he remarks that the given premises are not enough for his aim, to explain the nature of man. Therefore he adds other guiding principles for the second part in form of a second introduction like in the first part. We need a third principle beside the real beings (the ideas) and the things we perceive. He names it chora and the new form of "`causation"' ananke, necessity. These supplementary principles anable Timaeus to describe the world under our everyday conditions, they mediate the noetic world with the world of our senses. Here is the point we can see a surprising parallel in Kant's work. The Metaphysische Anfangsgründe der Naturwissenschaft correspond to the first part of the Timaeus, because here Kant exposes too the metyphysical foundation of the sciences. Later, in his last years he remarks, that there is a gap between these metaphysical principles and the physics (say of Newton or other). He seeks for a mediating principle and finds it in the "Äther" or "Wärmestoff." Kant was no more able to bring his idea to an end, we only have a lot of variating attempts, named by editors Opus postumum. But the aim of them is clear – and near by the aim that Plato aimed at – to mediate the noetic structure of the world with our everyday world. And this is evidently equivalent with the second introduction in the Timaeus. -/- Here some pages of the book-version: Erwin Sonderegger, Zur Funktion der Chora in Platons Timaios und des Äthers in Kants Übergangsschrift, Königshausen & Neumann, Würzburg 2015.

Although St. Albert the Great is known for his assimilation of Aristotle’s thought, he holds Plato in high regard. Yet Aristotle largely guides Albert’s understanding of Plato and Aristotelian criticism against him is repeated along Albert’s work. The objections raised in the first book of the Metaphysics are especially recurrent. Therefore to study Albert’s commentary on such objections in some detail, as we do in these pages, has considerable interest. Criticism against Plato focuses on his conception of the universal and (...) the separation of ideas. Moreover, Albert assimilates several platonic doctrines because, like many other Christian authors, he sees in the Timaeus a metaphysical approach, which is susceptible to be combined with his faith. Albert also believes to find a substantial agreement between the views of Plato and Aristotle at various points, including the question of form, despite differences in their expositions. (shrink)

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)

This paper provides a rational reconstruction of a Platonic trope bundle theory that is a live alternative to contemporary bundle theories. According to the theory, Platonic particulars are composed of what Plato calls images of Forms; contemporary metaphysicians call these tropes. Tropes are dependent on Forms and the Receptacle, while trope bundles are structured by natural kinds using the Phaedo's principles of inclusion and exclusion and the Timaeus’ geometrised elements, as well as by co-location in the Receptacle. Key elements (...) of discussion include persistence and abundance of Plato's tropes. The resulting theory is compared with contemporary trope bundle theories. (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.

A standard interpretation of Plato’s metaphysics holds that sensible particulars are images of Forms. Such particulars are fairly independent, like Aristotelian substances. I argue that this is incorrect: Platonic particulars are not Form images but aggregates of Form images, which are property-instances. Timaeus 49e-50a focuses on “this-suches” and even goes so far as to claim that they compose other things. I argue that Form images are this-suches, which are tropes. I also examine the geometrical account, showing that the geometrical (...) constituents of the elements are also Form images. Thus everything in the sensible world is composed of tropes. (shrink)

In this paper I argue that although the Republic’s tripartite theory of the soul is not explicitly endorsed in Plato’s late work the Laws, it continues to inform the Laws from beneath the surface of the text. In particular, I argue that the spirited part of the soul continues to play a major role in moral education and development in the Laws (as it did in earlier texts, where it is characterized as reason’s psychic ‘ally’). I examine the programs of (...) musical and gymnastic education in the Laws and highlight parallels to the accounts of the spirited part of the soul and its role in moral education and virtue that are offered in Republic and Timaeus. I also examine the educational role given to the laws themselves in Magnesia, and I suggest that the education provided through them is largely directed at the spirited part of the soul as well. (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.

Many scholars have denied that Plato’s argument about desire at Philebus 34c10–35d7 is related to his recollection arguments in the Meno and Phaedo, because it is concerned only with postnatal experiences of pleasure. This paper argues against their denial by showing that the desire argument in question is intended to prove the soul’s possession of innate memory of pleasure. This innateness interpretation will be supported by a close analysis of the Timaeus, where Plato suggests that our inborn desires for (...) food and drink derive from the primitive experiences of pleasure that have naturally been incorporated into the appetitive part of the soul. (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. (shrink)

Many assume that Plato's Form of the Good is a final cause. This might be true if one assumes an Aristotelian definition of final cause; however, I argue that if one adopts Plato's conception of final causation as evidenced in the Phaedo and Timaeus, the claim that the Form of the Good is a final cause for Plato is untenable.

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)

According to Marinus of Samaria, Proclus was the author of many philosophical doctrines. In particular he was the first to assert the existence of a kind of souls that are capable of simultaneously seeing several ideas and situated between the divine Intellect which embraces all things together by a single intuition, and the souls whose thoughts pass from one idea to another. In the following we are going to answer the question, what kind of souls did Proclus discover and why (...) did he thought it to be necessary to introduce them in his metaphysical system. To solve this problem it seems reasonable to clarify the mechanism of horizontal-vertical progression in Proclus’ philosophy, as well as to describe the general structure of the psychic level of reality embracing the so called Monad of “unparticipated” Soul and the multiplicity if its “participated” products: divine, demonic and human souls. Unlike some previous scholars, who alleged that souls discovered by Proclus were demonic or intelligent ones, I affirm that Marinus could have in mind hypercosmic participated souls, situated between the unparticipated monad of the psychic level of reality and the multiplicity of participated souls within the material cosmos. In support of this assumption I cite some relevant passages from Proclus’ Commentary on “Timaeus” and demonstrate that he named “hypercosmic” not only the unparticipated monad of Soul, but also souls of the so called “absolute” gods, which are both in touch with the sensible cosmos and above it because of animating eternal immaterial bodies consisting of supra-celestial light. In conclusion I try to establish the genuine authorship of the doctrine of hypercosmic souls and to answer the question, why did Marinus attribute it to Proclus. (shrink)

The Receptacle of the title is, of course, the ‘Receptacle of all becoming’ in Plato’s Timaeus. Plato likens it to a ‘nurse’, and even calls it a ‘mother’. He speaks of it as that in which its contents come to be, only in their turn to disappear from it. He compares it to a mass of gold which someone incessantly remoulds into different shape. He declares it completely unchanging: ‘it does not depart from its own character in any way'. (...) What is its character? It is the character of possessing and acquiring no character similar to that of any of the objects said to enter it and disappear from it. Plato says too that it is space; the receptacle is what makes it true that each of those objects is somewhere. And finally, as if he had not already given us far too much to digest of this very rich subject, Plato adds that the Receptacle shakes its contents with a sort of winnowing motion, and in fact was already doing this even before the craftsman god had formed this world of ours. The question of this paper is: what is the function of this multifariously conceived entity, or principle, the Receptacle? I shall approach by asking what its contents are. (shrink)
