At 47e–53c of the Timaeus Plato presents his most detailed metaphysical analysis of particulars. We are told about the construction of the physical universe, the ways we can and cannot talk about the phenomena produced, and about the two causes – Necessity and Intelligence – which govern the processes and results of production. It seems to me that we are told too much and too little: too much, because we have two accounts of the generation of phenomenal particulars – one, (...) the ‘formal account’, which makes use of the receptacle, Forms and form-copies, and a second, the ‘geometrical account’, which appeals to geometrical shapes, the Demiurge and, apparently, matter; too little, because there is insufficient guidance as to how to relate the two accounts.

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.

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)

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 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 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.

This study places Nāgārjuna and Plato in dialogue regarding how both seek to orient philosophy in the face of indeterminacy observed at the elemental level of existence, specifically, the indeterminacy of fire’s light. Looking to the elemental within Chōra and Śūnyatā, a directive becomes discernible for calibrating philosophy to this indeterminacy, and crucial limitations are disclosed, which expand philosophy by enabling a productive relation to the non-philosophical. What emerges are directives for language, which serve to modify philosophy’s violence towards the (...) world by striking a middle way between the binaries of reification and nihilism, speech and silence.

In this paper, I will discuss a certain conception of matter that Aristotle introduces in Metaphysics Z3. It is often assumed that Aristotle came to distinguish between matter and form only in his physical writings, and that this lead to a conflict with the doctrine of primary substances in the Categories that he tries to resolve in Z3. I will argue that there is no such conflict. In Z3, Aristotle seems to suggest that matter is what is left over when (...) we strip a thing of all its properties. I take it that he does not want us to strip away these properties by physical means or in our imagination. Rather, we are asked to strip a referring noun phrase of all its predicative parts. We are thus not supposed to be able to refer to something that has no qualities whatsoever, but to construct a phrase that refers to something that has properties without referring to its having them, and without implying which properties it has. The idea that there might be a way of referring to something definite without mentioning any of its qualities is platonic and it still underlies modern predicate logic. In Z3, Aristotle argues against this conception and thus against the basic idea of predicate logic. According to him, matter is at best an inseparable aspect of a primary substance, which substance is best referred to as a compound τóδε τι (“this such”). Matter is what the τóδε refers to as part of this phrase. But it cannot exist in separation from form, and we cannot refer to it by a separated term, without also referring to the substantial form of the substance of which it is an aspect. (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)

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)

Plato’s demiurge makes a series of questionable decisions in creating the world. Most notoriously, he endeavors to replicate, to the extent possible, some of the features that his model possesses just insofar as it is a Form. This has provoked the colorful complaint that the demiurge is as raving mad as a general contractor who constructs a house of vellum to better realize the architect’s vellum plans (Keyt 1971). The present paper considers the sanity of the demiurge’s reasoning in light (...) of Timaeus 32c5-33b1, where he invokes considerations of wholeness, completeness, uniqueness, and eternality in deciding to build the body of the world from all of each of the simple bodies. Since the passage makes no appeal to the demiurge’s intelligible model, one can mine it for indications of the value that the demiurge takes those features to have independent of mimetic goals. I argue that, for Plato, those features are intrinsically good-making and, thus, that it is not only appropriate for them to characterize Forms qua Forms but also that it is appropriate for the demiurge to aim at replicating them, to the extent possible, in his creation. In particular, I argue that the demiurge’s success in instilling a circumscribed version of each feature in his creation helps to qualify it as a genuine being despite the fact that it comes to be.

This paper offers a reconstruction of Xenocrates’ theory of indivisibles which would not commit him to the idea of ‘jerky motion’ criticized by Aristotle in Physica VI, yet would perfectly square with Plato’s Timaeus, the basis of Xenocrates’ canon. Relying on Alexander’s, Porphyry’s, and Themistius’s accounts of his theory, as well on a detailed analysis of De lineis insecabilibus, I suggest that Xenocrates’ minima, contrary to what Aristotle implies, are not to be understood as more or less stable particulars, like (...) tiny chunks of matter, moving about or leaping in physical space from point A to point B. Yet Xenocrates’ minima do remain ‘physical’ and ‘corporeal’ in a more Platonic sense of these words, not presupposing any kind of leaping, jumping, or jerking. This explains why Xenocrates associated the sensible realm with one of the three Fates, namely Clotho. (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)
