I argue that Plato, in theTimaeus, draws deep theoretical distinctions between sensation and affect, which comprises pleasure, pain, desire and emotion. Sensation (but not affect) is both ‘fine-grained’ (having orderly causal connections with its fundamental explanatory items) and ‘immediate’ (being provoked absent any mediating psychological state). Emotions, by contrast, are mediated and coarse-grained. Pleasure and pain are coarse-grained but, in a range of important cases, immediate. TheTheaetetusassimilates affect to sensation in a way theTimaeusdoes not. Smell frustrates Timaeus because it is (...) coarse-grained, although unlike pleasure and pain it is so by accident of physiology. (shrink)

_ Source: _Volume 11, Issue 1, pp 26 - 45 In his _Commentary on the Timaeus_, Porphyry of Tyre argued against the second-century Platonist Atticus’ thesis that the creation in Plato’s _Timaeus_ was a process from a point of time. This paper focuses on the summary of one of Porphyry’s arguments against this thesis exposed in Book 2 of Proclus’ _Commentary on the Timaeus_. It argues that Proclus does justice to Porphyry’s views and that the argument points to a classification (...) of powers in Porphyry’s metaphysics that has so far been neglected by scholars.

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.

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.

Galen is well known as a critic of Stoicism, mainly for his massive attack on Stoic (or at least, Chrysippean) psychology in "On the Doctrines of Hippocrates and Plato" (PHP) 2-5. Galen attacks both Chrysippus' location of the ruling part of the psyche in the heart and his unified or monistic picture of human psychology. However, if we consider Galen's thought more broadly, this has a good deal in common with Stoicism, including a (largely) physicalist conception of psychology and a (...) strongly teleological view of natural entities, shared features which are acknowledged in several treatises outside "PHP." Why, then, is Galen such a remorseless and negative critic of Stoicism in "PHP"? Various factors are relevant, including the shaping influence on Galen of the Platonic-Aristotelian (part-based) psychological framework. But, it is suggested here, an important underlying factor is the contrast between two ways of thinking about the part-whole relationship, a 'composition' and a 'structure' approach or an atomistic and holistic approach. This contrast is most evident and explicit in one section of "PHP" 5, where Galen, criticising Chrysippus' holistic psychology, denies that the Stoic thinker is entitled to use the concept of part at all. But the contrast is also seen as pervading Galen's response to Stoic thought more generally, in "PHP" and elsewhere, in ways that inform his explicit disagreements with Stoic theory. Stoicism is presented here as having a consistently 'structure' (or holistic) approach. Galen's approach is seen as more mixed, sometimes sharing, or aspiring towards, a holistic picture, and yet sometimes (especially in "PHP" 5), adopting a strongly 'composition' or atomistic standpoint. This (partial) contrast in conceptual frameworks is presented as offering a new perspective on Galen's critique of Stoic psychology in "PHP" and on his relationship to Stoic thought more generally.

One of the hardest questions to answer for a (Neo)platonist is to what extent and how the changing and unreliable world of sense perception can itself be an object of scientific knowledge. My dissertation is a study of the answer given to that question by the Neoplatonist Proclus (Athens, 411-485) in his Commentary on Plato’s Timaeus. I present a new explanation of Proclus’ concept of nature and show that philosophy of nature consists of several related subdisciplines matching the ontological stratification (...) of nature. Moreover, I demonstrate that for Proclus philosophy of nature is a science, albeit a hypothetical one, which takes geometry as its methodological paradigm. I also offer an explanation of Proclus’ view of what is later called the mathematization of physics, i.e. the role of the substance of mathematics, as opposed to its method, in explaining the natural world. Finally, I discuss Proclus’ views of the discourse of philosophy of nature and its iconic character. (shrink)

Within the Platonic (or Neoplatonic) dualistic conception of body and soul the difference between maleness and femaleness might appear to be a difference which only concerns the body, that is a difference which is not essential for determining who (or what) a certain human is. One might argue that, since humans are essentially their souls and souls are genderless, men and women are essentially equal. As my paper shows, though, Plato's and Proclus’ writings set out two ways of conceptualizing human (...) souls themselves as ‘sexed’ and of doing this in a way that female souls are determined to be inferior to male souls. By Plato's account, souls are indeed genderless in terms of their essence, but they attain maleness through virtuous and femaleness through vicious activities. Proclus, by contrast, conceptualizes souls as essentially ‘male’ or ‘female’. A soul in whose essence the Different predominates is female, while a soul in whose substance the Same predominates is male. And since the attainment and preservation of virtue depend on the strength of the Same, female souls are not vicious by Proclus’ account, but they bear a higher risk of becoming vicious. (shrink)

There are two types ofaisthēsisin theTimaeus, which involve distinct physiological processes and different kinds of soul, appetite and reason respectively. This distinction explains Timaeus’ ambivalent attitude towardsaisthēsis: on the one hand, it is one of the main causes of the disruption of the orbits of the immortal soul upon embodiment; on the other hand, it plays a central role in restoring the immortal soul to its original, god-like condition.

This dissertation is a collection of essays exploring the role of metaphor in Aristotle’s scientific method. Aristotle often appeals to metaphors in his scientific practice; but in the Posterior Analytics, he suggests that their use is inimical to science. Why, then, does he use them in natural science? And what does his use of metaphor in science reveal about the nature of his scientific investigations? I approach these questions by investigating the epistemic status of metaphor in Aristotelian science. In the (...) first essay, I defend an interpretation of metaphor as a type of heuristic reasoning: I claim that Aristotle uses metaphor to express conditions an explanation in natural science must meet if it is to explain regular, ordered change. These conditions specify the kinds of causes—particularly unmoved efficient causes—which the inquirer into nature is seeking. In the second essay, I look to Aristotle’s use of certain endoxa or common beliefs as explanatory principles in science, and show that his use of these principles is similar to his use of metaphor. In the final essay, I present a historical study of the analogy of art and nature, and I suggest that by looking to how the Greeks understood the role of inquiry in the arts, we can shed some light on Aristotle’s views concerning the method of inquiry he thinks the natural scientist should adopt.

Near the end of his speech, Timaeus outlines a theory of bodily health and disease which has seemed to many commentators loosely unified or even inconsistent . But this section is better unified than it has appeared, and gives us at least one important insight into the workings of physical causality in the Timaeus. I argue first that the apparent disorder in Timaeus’s theory of disease is likely a deliberate effect planned by the author. Second, the taxonomy of disease in (...) the passage consists of one genus subsuming two species. Third, in Timaeus’s theory, health lies between perfect stability and a chaos of all possible motions; this indicates a conception of health as the activation of the body's powers in the right way. A power is a property directed towards bringing about some change. Fourth, the activation of these powers can change depending on the location of their possessors. This last point shows that causation among the physical items in the Timaeus involves structures as well as pushes. (shrink)

In this paper, we highlight a number of difficulties concerning the relationship between the Critias and theT imaeus, notably a contradiction between Timaeus 27a-b and Critias 108a-c. On this basis we argue that the Critias must be considered spurious.

_ Source: _Volume 61, Issue 1, pp 43 - 59 Contemporary debate on Plato’s cosmogony often assumes that the ‘literal’ reading of the _Timaeus_ yields an account of creation, while the view that the cosmos always existed is non-literal. In antiquity, Taurus has been seen as a forerunner of the ‘non-literal’ interpretation. This paper shows, on the contrary, that Taurus’ argument for the sempiternity of the cosmos is a literalist one, relying on a strict linguistic analysis of _Timaeus_ 28b6-8.

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)

In this paper, I identify two distinct positions on the nature of the body in Plato’s dialogues. One view, which I call the pessimistic view, holds that the body is evil and as such represents an obstacle to one’s epistemic and moral development. Another view, which I call the optimistic view, holds that the body is not itself either evil or good, but rather is capable of becoming either. The two views are, I argue, incompatible. Worse still, each view is (...) individually incompatible with other claims that Plato is eager to advance in some dialogues. The pessimistic view, I argue, is incompatible with the thesis that one who has knowledge will not err. The optimistic view is incompatible with the thesis that no one errs willingly. Here I consider a number of passages in Plato’s dialogues where the nature of the body is featured, but focus particularly on passages from the Timaeus and Laws, which explicitly endorse the pessimistic and optimistic views, respectively. Plato’s views of the body, I suggest, have far reaching implications for his views on the sources of moral error and the power of knowledge in guiding right action. (shrink)
