A proof is given that there does not exist an event, that is not already in the past for some possible distant observer at the (our) moment that the latter is "now" for us. Such event is as "legally" past for that distant observer as is the moment five minutes ago on the sun for us (irrespective of the circumstance that the light of the sun cannot reach us in a period of five minutes). Only an extreme positivism: "that which (...) cannot yet be observed does not yet exist", can possibly withstand the conclusion concerned. Therefore, there is determinism, also in micro-physics.

Sir Arthur Eddington, the celebrated astrophysicist, made great strides towards his own 'theory of everything'in his last two books published in 1936 and 1946. Unlike his earlier lucid and authoritative works, these are strangely tentative and obscure - as if he were nervous of the significant advances that he might be making. This volume examines both how Eddington came to write these uncharacteristic books - in the context of the physics and history of the day - and what value they (...) have to modern physics. The result is an illuminating description of the development of theoretical physics, in the first half of the twentieth century, from a unique point of view: how it affected Eddington's thought. This will provide fascinating reading for scholars in the philosophy of science, theoretical physics, applied mathematics and the history of science. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Comic Business: Theatricality, Technique, and Performance Contexts in Aristophanic ComedyC. W. MarshallMartin Revermann. Comic Business: Theatricality, Technique, and Performance Contexts in Aristophanic Comedy. Oxford: Oxford University Press, 2006. xiv + 396 pp. 15 black-and-white plates. 3 black-and-white figs. 5 tables. Cloth, $115.The cover illustration of Martin Revermann's book on Aristophanic performance betrays the author's personal and intellectual debts: caricatures of five scholars thanked in the preface, drawn as (...) if they were characters in Clouds, including Oliver Taplin in a swing looking down from above like Socrates. It is a shame many libraries will not keep the cover, since the lighthearted image is quite revealing about the nature of this study, though without any intended association with the academic pedantry of the Thinkery. Following chapter 1, entitled "Comic Business" (3–7), really a short whirlwind of an introduction that raises many of the sorts of questions the book addresses, the structure of the book falls neatly into two parts: three chapters examine the nature of performance criticism of ancient comedy and address a wide range of specifics; three chapters address individual plays, Clouds, Lysistrata, and Wealth. Each chapter falls into well-labeled sections, which will facilitate ongoing reference to the book. Revermann's study aims at a theoretical sophistication that is needed if the study of ancient performance is to proceed meaningfully. While he does not engage with every issue he raises in sufficient depth, Revermann provides a crucial advance on previous discussions (the book comes thirty years after C. W. Dearden's Stage of Aristophanes and twenty-six years after Kenneth McLeish's Theatre of Aristophanes).Chapter 2, "Performance Criticism: Point and Methods" (8–65), addresses some important and underexplored methodological questions that often go unmentioned in such studies. After arguing that "no ancient statement known to [End Page 431] me... claims a necessary link between meaning and dramatic performance" (15), Revermann identifies a "nexus of competitive agendas and social performances" (22), building on those Wilson has described for the choregos. Many of the issues raised (non-competitive performances, pay for poets, the relative importance of dramatic festivals) are equally important for the study of tragedy, and the book generally raises issues that students of tragic performance will need to consider. A general vocabulary of theatre semiotics is introduced, helpfully, with specific examples examining how performance generally is framed.Revermann embarks on an ambitious project of replacing the "significant action" hypothesis (which assumes that every significant action within a Greek play is indicated by the words a character says) that has dominated discussions of ancient stagecraft. This is a very helpful discussion, and it is surely correct, culminating in a good articulation of Revermann's methodology (63–64). Again, the principal examples come from tragedy. However, when Revermann invokes the question of on-stage frogs (agreeing with my 1996 discussion, which in its way sought also to challenge the "significant action" hypothesis), I think he needlessly muddles the matter by imagining the possibility of subsequent, frogless performances, when, I would say, a great deal is lost as a result. Revermann's interest is more with the possibilities offered by performance generally (65: "'Why frogs?,' irrespective of their visibility"), and sometimes the nitty-gritty of specific staging choices is not pressed (comparison is made with the offstage songs of the cloud chorus on 200).Chapter 3 (66–106) addresses "Two Fundamental Problems." The first relates the performance script (as attested in our manuscripts) to a concept of authenticity, considering that many plays were reperformed in the fourth century and after. Given that issues of reperformance were barely acknowledged until the last decade (Easterling's 1994 discussion is subtitled "A Speculative Note"), Revermann provides a solid discussion, arguing that the scripts of both tragedy and comedy closely match what was performed in Athens. Inconsistencies exist, but they are mentioned; context-specific references in Aristophanes point to the primary script surviving. An appendix on the time allocated to a performance during a festival is relevant (333–37). Revermann argues that the scripts as we have them may not have been performed in their entirety during their initial performance, suggesting, for example, that one... (shrink)

This paper evaluates several recent efforts to interpret the work of Nāgārjuna through the lens of modern symbolic logic. An attempt is made to uncover the premises that justify the use of symbolic logic for this purpose. This is accomplished through a discussion of (1) the historical origins of those premises in the Indian and Tibetan traditions, and (2) how such assumptions prejudice our understanding of Nāgā rjuna’s insistence that he has no “proposition” (pratijñā). Finally, the paper sets forth an (...) alternative interpretation that takes into account the literary dimensions of Nāgārjuna’s writing. (shrink)

A modified Young double-slit experiment proposed by Wootters and Zurek is considered in which a system P of parallel plates covered with a photographic emulsion has been set up in the region where we would normally expect the central interference fringes. Because under certain conditions P makes it possible to conclude with much more than50% certainty through which of the two slits each particular photon passed, the relevant interference pattern becomes blurred. It is proved that this implies a retroactive effect (...) because the setup of P and the interaction of photons with P appear to influence the momentum transferred to the photons by the edges of the slits at an earlier stage of the experiment.

Aristotle's treatise De Interpretatione is one of his central works; it continues to be the focus of much attention and debate. C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system, basing this view upon a detailed chapter-by-chapter analysis.By treating the work systematically, rather than concentrating on certain selected passages, Whitaker is able to show that, contrary to traditional opinion, it forms (...) an organized and coherent whole. He argues that the De Interpretatione is intended to provide the underpinning for dialectic, the system of argument by question and answer set out in Aristotle's Topics; and he rejects the traditional view that the De Interpretatione concerns the assertion and is oriented towards the formal logic of the Prior Analytics. In doing so, he sheds valuable new light on some of Aristotle's most famous texts. (shrink)

I begin by quoting from two valuable recent works on Horace. Professor Brink in his Horace on Poetry writes: ‘The centre of the short piece lies in lines 21—34. Readers, among them critics and poets, had denied one aspect of the Odes which was surely above criticism—the striking originality of these poems. Horace's defence turns on the question of originality’ and ‘Epistle 19 is unique in that it alone among the literary satires and letters reiterates Horace's claim to be the (...) Latin fidicen’ . And Dr. McGann in his Studies in Horace's First Book of Epistles : ‘In Ep. 19... as in the literary satires, Horace is a practising poet or at least a very recently practising one, engaged in defending himself against hostile criticism’ and ‘As the only epistle concerned exclusively with literary matters, the nineteenth stands apart’.

This paper presents a new model for how the voting worked at the Athenian dramatic competitions, and demonstrates its viability mathematically. Previous proposals have either failed to take full account of the ancient sources or have not considered all the possible permutations of judging results. As is generally recognized, ten votes were cast, but in most circumstances not all were counted. Sections I-IV consider the tragic competition at the Dionysia, in which three competitors vied for the prize. For the questions (...) we consider, two likely cases are examined (when the votes are divided 4-3-3 and 5-3-2), then a random distribution covering all possible cases, and finally the situation when two competitors are favoured against a third (when the votes are divided 5-5-0, 5-4-1 and 4-4-2). Section I presents the proposal and situates it within the Athenian cultural context. Section II asks how many lots are typically drawn before a victory is obtained. Section III considers how other places are determined. Section IV introduces the question of 'fairness': does the person who receives the most votes actually win? Section V considers adjudication for comedies and at the Lenaia. Section VI considers dithyrambic competitions. (shrink)

This article discusses two complementary themes that play an important role in contemporary South African political philosophy: (1) the racist tradition in Western philosophy; and (2) the role of ubuntu in regaining an authentic African identity, which was systematically suppressed during the colonial past and apartheid. These are also leading themes in Mogobe Ramose’s African Philosophy Through Ubuntu. The first part concentrates on John Locke. It discusses the thesis that the reprehensible racism of many founders of liberal political philosophy has (...) lethally infected liberal theory. This view neglects the distinction between genesis and justification. Political liberalism has since cleansed itself of the prejudices of its spiritual ancestors. Liberal human rights exclude racism as a matter of principle. The second part discusses the claim that the ubuntu philosophy provides a better basis for a constitution in a modern society than political liberalism. A major problem is that ubuntu is an essentially contested concept. Some philosophers consider ubuntu to be a moribund notion (Matolino); others see it as a vital concept par excellence. In the latter case, it is elaborated from sundry incompatible political views, ranging from African nationalism (Ramose) via humanist communitarianism (Metz) to liberalism (Mboti). Conclusion: as an essentially contested ideological concept, ubuntu should not be a decisive constitutional standard for the application of state force. In contrast, the constitutional model of political liberalism provides a reasonable alternative, as it is designed precisely to solve the problem of social plurality and ideological contest.

Much has been written about the problematic passage towards the end of the Medea prologue-speech, in which the Nurse expresses fear concerning the intention of her mistress; problematic both in itself, especially as to the interpretation of lines 40–2, and in relation to lines 379–80, which are almost the same as 40–1; a most suspicious circumstance.

In this paper, it is argued that the prima facie conflict between special relativity and the quantum-mechanical collapse postulate is only apparent, and that the seemingly incompatible accounts of entangled systems undergoing collapse yielded by different reference frames can be regarded as no more than differing accounts of the same processes and events. Attention to the transformation properties of quantum-mechanical states undergoing unitary, non-collapse evolution points the way to a treatment of collapse evolution consistent with the demands of relativity.

Ogden spent over forty years attempting "to deal... with the whole of the linguistic problem." This study gives his work an enduring quality which is of particular relevance to late twentieth century linguistics.
