In lieu of an abstract, here is a brief excerpt of the content:Plato, Proclus, and the Limitations of Science S. SAMBURSKY I THE NEOPLATONICREVlV~of Plato's views on the physical world offers some highly interesting aspects to the historian of scientific ideas. There is first of all the interaction between a 600-year-old tradition and other philosophical systems that grew up during this long period and that exerted such a decisive influence on later antiquity. And there is further the magnificent development (...) of science--mathematics and astronomy in particular--in the period following Plato, reaching its climax in the Hellenistic era. This development introduced profound changes in the scientific world picture by adding a wealth of new facts to astronomy, mechanics, optics, and biology, and thus facing the later disciples of Plato with a difficult alternative : They could either assume an orthodox attitude by doubting the facts or at least belittling their significance for the Platonic doctrine; or else they could compromise by attempting to interpret the facts in the Platonic spirit--doing so by availing themselves of the well-known expedient of reading between the lines of the master's writings. It can, of course, not be denied that everything Plato has written on the physical world and on scientific cognition will always be, as it has been in antiquity, subject to interpretations. The task of a Platonic commentator is made even more difficult by his poetic style, his predilection for allegory, and his frequent use of allusions at the very moment when one expects systematic analysis. The increasing anti-metaphysical bias of modern science combined with the fact that Plato himself was neither a practicing scientist nor a creative mathematician led to the disparagement of his contribution to scientific thought in the last centuries. This applies in particular to the Timaeus,where the main tenets of PIato's scientific doctrine are expounded. However, on the whole, this negative attitude is not justified. The consistency and significance of Plato's epistemology of science is borne out by his statements in the Timaeusif they are taken together with his assertions concerning the role of mathematics in the cognition of nature and his appeal to the astronomers to "save the phenomena" of the planetary motions. Careful consideration of all these passages, regarded as a coherent whole, will show in the first place that Plato's philosophy of science does not fall short of his other great contributions to philosophy and human thought. It will further serve as a background against which the significant shift of emphasis that is found in Proclus's evaluation of the capacity of the human mind for the progressive understanding of nature will be seen. We all know of Plato's fundamental belief that the sensible world, i.e., the obiect of physical inquiry, is only an image of the inaccessible world of ideas. The intelligible world, the ultimate reality, is permanent and unchangeable, whereas [11 2 HISTORY OF PHILOSOPHY the material world is a world of transience and change. Every possible description of the physical world is therefore by necessity only a plausible story, not rising above the level of probability. This is the background of the celebrated passage in the Timaeus (29 C) : If then.., we prove unableto render an accountat all points entirely consistentwithitself and exact,you must not be surprised.If we can furnish accountsno less likely than any other, we must be content,rememberingthat I who speak and you my judges are onlyhuman, and consequently it is fittingthat we should, in these matters, accept the likelystory and look for nothingfurther. Here science has once and forever been assigned a place below the absolute truth, in view of the transient nature of the physical world and the role of the sensible world as an image of truth. Can some assertion be made as to the essence of this image? What is the ontological significance of all the changes and transmutations and what is the mechanism of that permanent generative process whose various components blend into the one perceptible unit which we call "nature"? Plato's answer is given in his allegory of the struggle between Reason and Necessity (Timaeus 48 A) : "The generation of this universe was a mixed result of the combination... (shrink)

From the meagre fragments available, Sambursky has carefully reconstructed the basic physical concepts of the Stoa, emphasizing the continuum theory developed by Chrysippos and Poseidonios. Stoic physics, in contrast with Democritean atomism, has been largely neglected, in spite of its relevance to contemporary theories of continuity. Sambursky's contribution should overcome this omission to a great extent, and, together with Mates' and Lukasiewicz's work in Stoic logic, enable us to comprehend the non-ethical features of Stoic thought. Included is a (...) 30 page appendix giving English translations of the relevant classical fragments.--L. S. F. (shrink)

This article aims to shed light on certain aspects of Iamblichus’ theory of time that have not been sufficiently examined to date in the scholarly literature. As of today, there are a mere handful of scholarly works tackling Iamblichus’ solutions to the paradoxes of time in particular, and his contribution to the developments of the Neoplatonic theory of the subject more generally. This article attempts to redress the lack of literature on this topic by examining Iamblichus’ response to Aristotle’s and (...) Pseudo-Archytas’ theories of time. It begins with a brief survey of the philosophical developments that led to and were formative for Iamblichus’ philosophical explorations of the area in question. Then it moves on to provide a detailed account of Iamblichus’ own unique and puzzling theory of time. The author applies the method of comparative analysis, scrutinizing Iamblichus’ solution to the paradoxes of time against the backdrop of Aristotle’s and Pseudo-Archytas’ theories. The author identifies firm scholarly grounds for doing so from within the tradition of Iamblichus studies initiated by the ground-breaking research of Shmuel Sambursky and Salomon Pines and continued, inter alia, in the subtly nuanced analysis of Richard Sorabji and John Dillon. The author concludes that Iamblichus successfully resolved the paradoxes of time and that his conception lent itself to a more effective highlighting of the ordering function of time. (shrink)

The introduction of the concept of capital inCapital– with the words ‘we find’ – has provoked a great deal of discussion about the precise relation between the categories of simple circulation and the concept of capital. In this article, I argue that Marx derives the concept of capital by way of an analysis of the immanent contradictions of money, and that this dialectical derivation can be understood as a conceptual movement in which the concepts of money and capital progressively change (...) their modal status. Furthermore, I examine the development of this transition to capital throughout Marx’s writings from the period 1857 to 1872, arguing that the same arguments can be found in all the relevant writings. Finally, the article provides a critical review of the literature on the transition to capital. (shrink)

This paper gives an ethical argument for temporarily waiving intellectual property protections for COVID-19 vaccines. It examines two proposals under discussion at the World Trade Organization : the India/South Africa proposal and the WTO Director General proposal. Section I explains the background leading up to the WTO debate. Section II rebuts ethical arguments for retaining current IP protections, which appeal to benefiting society by spurring innovation and protecting rightful ownership. It sets forth positive ethical arguments for a temporary waiver that (...) appeal to standing in solidarity and holding companies accountable. After examining built-in exceptions to existing agreements and finding them inadequate, the paper replies to objections to a temporary waiver and concludes, in section III, that the ethical argument for temporarily waiving IP protection for COVID-19 vaccines is strong. There are no data in this work. (shrink)

Socrates wrote nothing; Plato's accounts of Socrates helped to establish western politics, ethics, and metaphysics. Both have played crucial and dramatically changing roles in western culture. In the last two centuries, the triumph of democracy has led many to side with the Athenians against a Socrates whom they were right to kill. Meanwhile the Cold War gave us polar images of Plato as both a dangerous totalitarian and an escapist intellectual. And visions of Plato have proliferated at the heart of (...) postmodern critiques of the very idea of metaphysics and politics. Plato's Progeny begins with an account of modern responses to the trial of Socrates and the controversial question of Socrates' relation to Plato. At its centre are two chapters exploring the idea of Platonic origins in and for philosophy, and of Platonic foundations for philosophical politics. Exploring unfamiliar as well as familiar invocations of Plato, Melissa Lane argues that twentieth-century ideological battles have obscured the importance of Socratic individualism, the nature of Platonic ethics, and the value of Platonic politics. Succinct and clearly written, this is an ideal guide for everyone interested in the way philosophers are still writing footnotes to Plato. (shrink)

The aim of this inquiry is to investigate Heidegger's ontology of technology. We will show that this ontology is aporetic. In Heidegger's key technical essays, ?The question concerning technology? and its earlier versions ?Enframing? and ?The danger?, enframing is described as the ontological basis of modern life. But the account of enframing is ambiguous. Sometimes it is described as totally binding and at other times it appears to allow for exceptions. This oscillation between, what we will call total enframing and (...) partial enframing, is underscored in the work of two influential scholars of Heidegger's later thought, Hubert Dreyfus and Iain Thomson. We will show that like Heidegger, Dreyfus and Thomson unwittingly perpetuate this dilemma that ultimately covers up the aporetic structure of enframing. (shrink)

This paper discusses Wittgenstein's take on the problem of other minds. In opposition to certain widespread views that I collect under the heading of the “No Problem Interpretation,” I argue that Wittgenstein does address some problem of other minds. However, Wittgenstein's problem is not the traditional epistemological problem of other minds; rather, it is more reminiscent of the issue of intersubjectivity as it emerges in the writings of phenomenologists such as Husserl, Merleau-Ponty, and Heidegger. This is one sense in which (...) Wittgenstein's perspective on other minds might be called “phenomenological.” Yet there is another sense as well, in that Wittgenstein's positive views on this issue resemble the views defended by phenomenologists. The key to a proper philosophical grasp of intersubjectivity, on both views, lies in rethinking the mind. If we conceive of minds as essentially embodied we can understand how intersubjectivity is possible. (shrink)

No part ot Plato's writings has been more debated than the three similes in Books VI.-VII. of the Republic, and still there is a diversity of opinion about their meaning. I believe that most of these difficulties arise from certain assumptions about their purpose which need revision. The current view applies the Cave to the Line, as Plato seems to direct, and this application, which is itself attended by considerable difficulties, leads to an assimilation of the two figures till they (...) seem to have much the same content and purpose. Again, as this makes the lower line appear to be the phenomenal world, it is thought that the simile of the sun foreshadows the theme of the Line by hinting at a connexion between the intelligible and the sensible which is made more explicit in the Line. Thus the group of similes seem mainly intended to show the dependence of Becoming upon Being. This paper will argue that such a view depends upon the misrepresentation of the symbolism adopted by Plato, that two antithetical groups of symbols are confused with one another, and that symbols are even identified with antitypes. Owing to these misinterpretations the Form of the Good has been mistaken for a material cause; both the Line and the Cave have been thought to reveal Plato as embarrassed by a dualism between sense and intellect, and the purpose of the Cave in particular, since the error is cumulative, has been completely obscured. This paper will attempt to substitute for current accounts another interpretation which will relate the three similes closely with the political arguments of Book VI., and with the Platonic education which is set forth in close connexion with them.

Stoic physics, based entirely on the continuum concept, is one of the great original contributions in the history of physical systems. Building on The Physical World of the Greeks, the author describes the main aspects of the Stoic continuum theory, traces its origins back to pre-Stoic science and philosophy, and shows the attempts of the Stoics to work out a coherent system of thought that would explain the essential phenomena of the physical world by a few basic assumptions. Originally published (...) in 1987. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

In classical American pragmatism, fallibilism refers to the conception of truth as an ongoing process of improving human knowledge that is nevertheless susceptible to error. This paper traces appearances of fallibilism in Jewish thought in general, and particularly in the halakhic thought of Eliezer Berkovits. Berkovits recognizes the human condition’s persistent mutability, which he sees as characterizing the ongoing effort to interpret and apply halakhah in shifting historical and social contexts as Torat Ḥayyim. In the conclusion of the article, broader (...) questions and observations are raised regarding Jewish tradition, fallibility, and modernity, and the interaction between Judaism and pragmatism in the history of ideas.

At Aristophanes, Equites 230–2, one of the slaves who speak the prologue informs the audience that, when the Paphlagonian appears onstage, his mask will not resemble him, for the σκεoπoιoí were afraid to make one that depicted him accurately. In an important article, K. J. Dover argued that it must in fact have been very difficult to create easily recognizable portrait-masks, and suggested that the joke in Eq. 230–2 may be that the Paphlagonian's mask is horribly ugly but allegedly still (...) nowhere near ugly enough. In response, D. Welsh, following an anonymous ancient commentator on Lucian, argued that Cratinus fr. 228 K-A shows that the historical Kleon had strikingly unattractive eyebrows. Had anyone wished to caricature the demagogue's physical appearance, therefore, he coule easily have done so, and portrait-masks may not have been so uncommon after all. Welsh's argument is at first glance quite appealing, and has been endorsed without further comment or argument by Sommerstein and Storey. I suggest, however, that the ancient commentator was confused, and that Cratinus’ remark is much more easily explained by reference to what is known about the use of facial expression as a communicative strategy in classical and early Hellenistic Athens, particularly as it appears in the comic poets. Kleon's eyebrows were probably no more ugly than those of anyone else, although he may have used them in an offensive way, and as Dover saw long ago, Eq. 230–2 cannot be taken as evidence for the use of portrait-masks on the late 5th-century comic stage.
