Discusses the importance of the early history of Greek mathematics to education and civic life through a study of the Parthenon and dialogues of Plato.

وجه الوهی فلسفه ارسطو، و به طور خاص وجه الوهی غایت‌شناسی او، مسئله‌ای مناقشه‌برانگیز و حتی شدیداً مورد انکار است؛ چرا که تفسیرهای معاصر غایت‌شناسی، از یک سو غایت‌شناسی الهیاتی را تبیین جهان به عنوان فعل قصدمندانه خالقی حکیم تلقی کرده، و از سوی دیگر غایت‌شناسی ارسطو را صرفاً روشی برای تبیین کارکردهای جواهر طبیعی و افعال انسانی می‌دانند. در نتیجه غایت‌شناسی ارسطو فاقد هر گونه دلالت الهیاتی تلقی می‌شود. این نوشتار با نظر به اوصاف امر الهی در اندیشه ارسطو (...) نشان می‌دهد که او در حوزه زیست‌شناسی و اخلاق، گرچه پای تبیین‌های غایت‌شناختی به معنای طراحی هوشمند را به میان نمی‌کشد، در عین حال، کارکرد نهایی انواع طبیعی زنده و نوع انسان را با ارجاع به عنصری الهی در آنها تبیین می‌کند. به بیان مشخص‌تر، در انواع طبیعی زنده فقط نوع است که از جهت سرمدیت‌اش در جایگاه غایت به معنای حقیقی قرار می‌گیرد، حال آن که در انسان، غایت نهایی با ارجاع به عنصر الوهی محقق در هر فرد یعنی عقل احراز می‌شود. پس خدا به عنوان نمونۀ ایدئال تحققِ حیاتِ سرمدیِ معقول لحاظ می‌شود و غایتمندی جهان طبیعی زنده و جهان انسانی چیزی نیست مگر تشبه به این حیات سرمدی. بنابراین غایت‌شناسی ارسطو واجد استلزامات صریح الهیاتی است و چهارچوبی هستی‌شناختی را برای تفسیر عقلانی مفهوم سعادت در فلسفه‌های دینی فراهم می‌سازد.

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)

This essay re-examines Kierkegaard's view of Socrates. I consider the problem that arises from Kierkegaard's appeal to Socrates as an exemplar for irony. The problem is that he also appears to think that, as an exemplar for irony, Socrates cannot be represented. And part of the problem is the paradox of self-reference that immediately arises from trying to represent x as unrepresentable. On the solution I propose, Kierkegaard does not hold that, as an exemplar for irony, Socrates is in no (...) way representable. Rather, he holds that, as an exemplar for irony, Socrates cannot be represented in a purely disinterested way. I show how, in The Concept of Irony, Kierkegaard makes use of 'limiting cases' of representation in order to bring Socrates into view as one who defies purely disinterested representation. I also show how this approach to Socrates connects up with Kierkegaard's more general interest in the problem of ethical exemplarity, where the problem is how ethical exemplars can be given as such, that is, in such a way that purely disinterested contemplation is not the appropriate response to them.

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)

_ 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.

El concepto de _physis_ y sus derivados aparecen cientos de veces en los diálogos de Platón. Dado el carácter poco sistemático de su autor y los muchos años que dedicó a la escritura filosófica, no debe sorprender la diversidad de sentidos en que emplea un término ya de por sí complejo y polisémico. Por otra parte, Platón recoge, sintetiza y reelabora algunas de las concepciones fundamentales de la _physis_, siendo de especial relevancia las de los filósofos pluralistas, interesándose por los (...) elementos constitutivos del mundo físico y tomando partido en la discusión en torno a su carácter, bien mecánico, bien teleológico. En este estudio se analiza tanto la asimilación platónica de la física presocrática, como la influencia ejercida en el planteamiento aristotélico, especialmente por lo que respecta a la causalidad final y al principio del movimiento.

_ Source: _Volume 63, Issue 2, pp 117 - 147 I argue that Plato, in the _Timaeus_, draws deep theoretical distinctions between sensation and affect, which comprises pleasure, pain, desire and emotion. Sensation is both ‘fine-grained’ and ‘immediate’. Emotions, by contrast, are mediated and coarse-grained. Pleasure and pain are coarse-grained but, in a range of important cases, immediate. The _Theaetetus_ assimilates affect to sensation in a way the _Timaeus_ does not. Smell frustrates Timaeus because it is coarse-grained, although unlike pleasure (...) and pain it is so by accident of physiology. (shrink)

Plato tries to explain the becoming of the cosmos by referring to the concepts of order and disorder. Scholars have usually focused on the relationship between the cosmos and the demiurge that Plato puts forward to explain the reasonable development. Along these lines, scholarship has examined the providential role played by both the demiurge and the soul of the world. Yet, an interesting prob­lem still remains open: what exactly is the function of disorder? What is the sense of the concept (...) of a perfectly established order if we do not know the manner in which it is achieved, since we have no understand­ing of the conditions that make it possible? Pursuing this line of thought, one may point to a providential role of the disorder given the balance of forces that operates in Plato’s cosmic becoming. (shrink)

Hackforth and Menn make a strong case for the identity of nous and the demiurge in Plato, but I argue that it does not hold in the case of the Philebus, where the demiurge is kept in the background, and the world-soul is in fact the referent in the passage assigning nous to the class of cause as governor of the universe. In the Statesman, the world-soul had had to own the problem of natural catastrophe, and I suggest that in (...) the Philebus the role and functions of the world-soul are enhanced in an attempt to make it the basis for a solution to that problem.

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 his opening speech, Timaeus argues that the cosmos must be the product of a craftsman looking to an eternal paradigm. Yet his premises seem at best to justify only that the world could have been made by such a craftsman. This paper seeks to clarify Timaeus’ justification for his stronger conclusion. It is argued that Timaeus sees a necessary role for craftsmanship as a cause that makes becoming like being.

Readers of Plato since antiquity have generally taken Socrates’ intellectual autobiography in the Phaedo as a signal of his turn away from the study of natural philosophy. They have turned instead to characters such as Timaeus for evidence of Plato’s pursuit of physics. This article argues that Plato’s Socrates himself developed a philosophy of nature in his criticism of Anaxagoras and his subsequent philosophic pursuits. Socrates’ autobiography places the study of nature in a foundational position within the development of his (...) philosophic method. In the Apology, Socrates further elaborated his investigation into nature through his understanding of theology. Finally, in the Phaedrus, Socrates connects the study of nature with the study of rhetoric as tools for virtue. Therefore, Plato’s Socrates does not reject or abandon physics, as has often been suggested, but rather, he incorporates it into his own philosophic project and challenges its practitioners to connect their own inquiries with human affairs.

In De Anima I 4, Aristotle describes the intellect (nous) as a sort of substance, separate and incorruptible. Myles Burnyeat and Lloyd Gerson take this as proof that, for Aristotle, the intellect is a separate eternal entity, not a power belonging to individual humans. Against this reading, I show that this passage does not express Aristotle’s own views, but dialectically examines a reputable position (endoxon) about the intellect that seems to show that it can be subject to change. The passage’s (...) argument for the indestructibility of intellect via an analogy to perception does not fit with Aristotle’s own views. Aristotle thinks that perception operates via bodily organs, but denies this of understanding. He also requires separability from the body for indestructibility, something this analogy rules out. However, Aristotle’s Platonist interlocutors may well endorse such an argument. My dialectical interpretation best resolves the interpretative difficulties and explains its place in the larger context, Aristotle’s discussion of Platonist views on the soul. Aristotle presents a challenge to his insistence that the soul is subject to change, dialectically resolves that challenge, and then ends by reserving the right to give a different account of the intellect.

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)

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)

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)

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.

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.

Plato treats of the topic justice in the Republic, offering the concept of harmony as a perspective from which to examine this difficult concept. An ideal existing in a realm that is separate from the human and physical cosmos, justice is difficult to explain and even more so to achieve. Plato's disenchantment with his beloved city urges him on in this difficult task, especially difficult because the word harmony refers to tuning patterns for lyres and not to agreeable blending of (...) musical notes. Does he achieve his goal? (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.

The use of teleological language in biology is burdened with many difficulties. Speakers in everyday and scientific discourse confuse functions with purposes and misunderstand functionality, finality, and intentionality. The paper is structured into three sections. In the first part the difference between Platonic supranatural and Aristotelian quasi-natural account of teleology will be explained, with examples from the history of philosophy of biology. The second part will present the Darwinian approach to etiology that constitutes a more sound alternative to the teleological (...) explanation. In the last section I will briefly introduce the teleological bias that is studied by developmental and cognitive psychologists. I believe that this psychological inclination is the real source of intuitive worldviews that are incompatible with contemporary science. (shrink)
