The basic idea of his Origin of Species is that in nature there is a process similar to what goes on in the breeding of domestic plants and animals. If a breeder wants to produce a variety with certain characteristics, he/she keeps an eye out for individuals that have some approximation to those characteristics and breeds from them and not from individuals that do not have something like the desired characteristics. The other individuals may be destroyed, or they may just (...) be segregated; at any rate they are not allowed to breed with the selected stock. The breeder follows this policy also with the second generation of the offspring of the selected individuals of the first generation; those that after all do not have the desired characteristics are rejected, those that do are selected to produce the third generation, and so on. The whole process presupposes some degree of variability within the plant or animal being bred from. There have to be spontaneously produced individuals with something like the desired characteristics for the breeder to select. What can be accomplished by selection breeding depends of the range of variation that occurs spontaneously. (Hence the topic of Darwin's book of 1868, Variation of Plants and Animals under Domestication.) See in the Readings book the picture of the different breeds of pigeons from the Illustrated London News, 1864; Darwin was a pigeon fancier. (shrink)

Transcription initiation by σ54–RNA polymerase (RNAP) relies explicitly on a transient interaction with a complex molecular machine belonging to the AAA+ (ATPases associated with various cellular activities) superfamily. Members of the AAA+ superfamily convert chemical energy derived from NTP hydrolysis to a mechanical force used to remodel their target substrate. Recently Bordes and colleagues,1 using a protein fragmentation approach, identified a unique sequence within σ54‐dependent transcriptional activators that constitutes a σ54‐binding interface. This interface is not static, but subject to nucleotide‐dependent (...) movement which may represent a common mechanism for controlling output that has been adopted by other AAA+ proteins.

The late John Burrow, one of the most stimulating promoters of the distinctively interdisciplinary enterprise that is Intellectual History, was a vital member of what has become known as the ‘Sussex School’. In exploring the resonances of his singular and richly idiosyncratic contribution, this article places his unique historical sensibility within a series of interpretative contexts, demonstrating the vitality of writings that will continue to inspire and inform scholarship in the field for decades to come. ☆ The Sussex Centre for (...)

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)

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.

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)

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)

Quantum theory predicts that, e.g., in a Stern-Gerlach experiment with electrons the measured spin component $S_Z = \pm \frac{1}{2}$ does not come about by an adjustment at the last moment, a forced “flipping” or “tilting” of the spin (vector), which would imply z-angular momentum exchange between particle and instrument, but will afterward appear to have had the value $\frac{1}{2} or - \frac{1}{2}$ already before the measurement. Because an electron spin cannot have components $ \pm \frac{1}{2}$ in all directions at the (...) same time, the measuring direction has a “privileged” status before the measurement, however we choose that direction, which implies a retroactive effect. A second proof of retroactivity is derived from a special case of the paradox of Einstein, Podolsky, and Rosen. It is strongly suggested by our result that, in essential respects, both Bohr and Einstein were right in their famous controversy about determinism and considering microprocesses “as a whole.”.

As a drama and a poem theEumenidesis often regarded with unease. It brings theOresteiato a conclusion; but its account of Athens and the Areopagus seems to many readers inspired more by patriotism than a sense of dramatic unity. Hence much attention has been devoted to Aeschylus' supposed political message in the play; as a result, the question of its fitness to crown the trilogy recedes into the background or even vanishes. On the other hand, those whose concern is with Aeschylus' (...) poetry tend to ignore his ‘politics’. The purpose of this paper is twofold. First, it seeks to vindicate Aeschylus the artist: to show, that is, how the founding of the homicide court and the cult of the Semnai on the Areopagus in Athens properly marks the end of the troubles of the Argive Atridae, and how the sufferings and guilt of individual men and women are resolved in a city's institutions. In pursuing this aim, it also has to consider, and try to define, the relation of the tragedian to his audience and to contemporary society. My concern, then, is with the individual and the community, both within the play and behind it. (shrink)

Doing Educational Administration is the final part in a three volume series by Evers and Lakomski presenting their perspective on educational administration. The first volume, Knowing Educational Administration , established the importance of epistemological issues in the international field of educational administration and suggested a new, post-positivist approach to research. The theoretical approach presented in the first volume was further examined in Exploring Educational Administration, where the authors' theories were considered in an applied context. In this, the third and final (...) volume, the authors conclude their presentation of their post-positivist theory by demonstrating how their account of knowledge and cognition shapes the content and structure of administrative practice. Built around a set of basic issues in the practice of educational administration where the role of condition is of primary importance, Evers and Lakomski produce a comprehensive and persuasive applied theory of administrative practice.

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.

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)

(Expected) adverse effects of the ‘ICT Revolution’ on work and opportunities for individuals to use and develop their capacities give a new impetus to the debate on the societal implications of technology and raise questions regarding the ‘responsibility’ of research and innovation (RRI) and the possibility of achieving ‘inclusive and sustainable society’. However, missing in this debate is an examination of a possible conflict between the quest for ‘inclusive and sustainable society’ and conventional economic principles guiding capital allocation (including the (...) funding of research and innovation). We propose that such conflict can be resolved by re-examining the nature and purpose of capital, and by recognising mainstream economics’ utilitarian foundations as an unduly restrictive subset of a wider Aristotelian understanding of choice.
