The paper examines the connection between Aristotle's theory of generated substance and his notion of potentiality in "Metaphysics" Θ.7. Aristotle insists that the matter of a substance is not what that substance is, against a competing view that was widely held both in his day and now. He coined the term thaten (ἐ[unrepresentable symbol]νινονον) in order to make this point. The term highlights a systematic correspondence between the metaphysics of matter and of quality: the relationship between a thing and its (...) matter is like the relationship between a qualified thing and the relevant quality. It is argued that Aristotle's view about the matter of particular substances is connected with his view about ultimate matter. His conception of the matter of particular substances allows him to block an argument, from Plato's "Timaeus", that ultimate matter must be something imperceptible and lacking all perceptible qualities. Aristotle uses the term thaten to introduce an alternative conception of ultimate matter on which ultimate matter might well be an ordinary perceptible kind of thing. (shrink)

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.

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)

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 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.

At Timaeus 48e2–52d4 Timaeus sets out to establish that there are three principles or kinds underlying the creation of the cosmos, not just the two he acknowledged earlier. The way he does so is not simply by adding an account of the third kind to the accounts of being and becoming that he has already given. Rather he does so by showing how each of the three differs from the others. It has not been noticed how this procedure structures the (...) receptacle passage. The passage divides up into three parts, each punctuated by a list of the three kinds in a significant order. If we take X, Y and Z to stand for ‘becoming’, ‘being’ and ‘receptacle’ ’ respectively, the structure is X≠Z, X≠Y, Y≠Z. By showing the distinctness of each pair, Timaeus demonstrates that all the kinds are distinct and that they are indeed three in number. (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.

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)

In the Timaeus, Plato makes a distinction between reason and necessity. This distinction is often accounted for as a distinction between two types of causation: purpose oriented causation and mechanistic causation. While reason is associated with the soul and taken to bring about its effects with the good and the beautiful as the end, necessity is understood in terms of a set of natural laws pertaining to material things. In this paper I shall suggest that there are reasons to reconsider (...) the latter part of this account and argue for a non-mechanistic understanding of necessity. I will first outline how the notion of necessity is introduced in the dialogue. I will then show how a mechanistic account of necessity fails to capture Plato’s purpose of treating it as a causal factor; and, finally, argue that this purpose is better understood as an attempt, on Plato’s part, to account for the causal origin of disorder and irrationality, an origin articulated in terms of a pre-cosmic situation and the notoriously difficult notion of the third kind.

This dissertation is a study of appetite in Plato’s Timaeus, Republic and Phaedrus. In recent research is it often suggested that Plato considers appetite (i) to pertain to the essential needs of the body, (ii) to relate to a distinct set of objects, e.g. food or drink, and (iii) to cause behaviour aiming at sensory pleasure. Exploring how the notion of appetite, directly and indirectly, connects with Plato’s other purposes in these dialogues, this dissertation sets out to evaluate these ideas. (...) By asking, and answering, three philosophically and interpretatively crucial questions, individually linked to the arguments of the dialogues, this thesis aims to show (i) that the relationship between appetite and the body is not a matter of survival, and that appetite is better understood in terms of excess; (ii) that appetite is multiform and cannot be defined in terms of a distinct set of objects; and (iii) that appetite, in Plato, can also pertain to non-sensory objects, such as articulated discourse. -/- Chapter one asks what the universe can teach us about embodied life. It argues that Plato, in the Timaeus, works with an important link between the universe and the soul, and that the account of disorder, irrationality and multiformity identifying a pre-cosmic condition of the universe provides a key to understanding the excessive behaviour and condition of a soul dominated by appetite. -/- Chapter two asks why the philosophers of the Republic’s Kallipolis return to the cave, and suggests that Plato’s notion of the noble lie provides a reasonable account of this. By exploring the Republic’s ideas of education, poetry and tradition, it argues that appetite – a multiform and appearance oriented source of motivation – is an essential part of this account. -/- Chapter three asks why Socrates characterizes the speeches of the Phaedrus as deceptive games. It proposes that this question should be understood in the light of two distinctions: one between playful and serious discourse and one between simple and multiform. It argues that the speeches of the Phaedrus are multiform games, and suggests that appetite is the primary source of motivation of the soul addressed, personified by Phaedrus. -/- . (shrink)
