Environmental variability has been proposed as an important mechanism in behavioral psychology, in ecology and evolution, and in cultural anthropology. Here we demonstrate its importance in simulational studies as well. In earlier work we have shown the emergence of communication in a spatialized environment of wandering food sources and predators, using a variety of mechanisms for strategy change: imitation (Grim, Kokalis, Tafti & Kilb 2000), localized genetic algorithm (Grim, Kokalis, Tafti & Kilb 2001), and partial training of neural nets on (...) the behavior of successful neighbors (Grim, St. Denis & Kokalis 2002). Here we focus on environmental variability, comparing results for all of these mechanisms in a range of different environments: (a) environments with constant resources, (b) environments with random resources around the same mean, and (c) sine-wave variable environments with cycles of ‘boom and bust’. Communication, it turns out, is strongly favored by environmental variability on the pattern of ‘boom and bust.'. (shrink)

This article addresses the important question of how “upper”-caste power is reproduced in contemporary India, in the face of organized challenges from below. It argues that this process turns on the reproduction of castelessness. A long-standing site for the cultivation of castelessness has been the postcolonial census, which has limited the enumeration of caste to certain nonelites for the purposes of affirmative action reservations. However, in the aftermath of an intensive campaign to include a full castewise enumeration in Census 2011, (...) the political leadership of the Indian National Congress Party conceded and reversed seventy years of census policy on caste. This article examines the institutional pushback within the executive bureaucracy in the year following the public concession to change census policy on caste. In doing so, it shows how bureaucratic actions and inactions reproduce both castelessness and upper-caste power in contemporary India. (shrink)

De Interpretatione is among Aristotle's most influential and widely read writings; 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. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

The ‘international’ electrical units, initially defined by the International Electrical Congress of Chicago in 1893, represented a major step forward in international electrical standardisation. Yet they were flawed both theoretically and technically, were adopted inconsistently in different countries and were soon subject to criticism and revision. This paper addresses the extent to which the international units—notwithstanding their flaws—were in fact adequate for the needs of engineering, commerce and science at the time, and concludes that the practical position was actually very (...) satisfactory. It also addresses how the international electrical units came in to being, in the context of alternative philosophies of the nature of the standardisation process—that it can be essentially central or local. The central influence on the international units was the series of international electrical congresses of the late nineteenth century, which I conclude were a highly unsatisfactory mechanism, responsible for many of the weaknesses in the resulting standards. In contrast, I argue that it was local influences, the networks of scientists and standards laboratories that defined and maintained the standards, which gave them their strength.Keywords: International; Standardisation; Electrical units; Ohm; Congress.

We work with a large spatialized array of individuals in an environment of drifting food sources and predators. The behavior of each individual is generated by its simple neural net; individuals are capable of making one of two sounds and are capable of responding to sounds from their immediate neighbors by opening their mouths or hiding. An individual whose mouth is open in the presence of food is “fed” and gains points; an individual who fails to hide when a predator (...) is present is “hurt” by losing points. Opening mouths, hiding, and making sounds each exact an energy cost. There is no direct evolutionary gain for acts of cooperation or “successful communication” per se. In such an environment we start with a spatialized array of neural nets with randomized weights. Using standard learning algorithms, our individuals “train up” on the behavior of successful neighbors at regular intervals. Given that simple setup, will a community of neural nets evolve a simple language for signaling the presence of food and predators? With important qualifications, the answer is “yes.” In a simple spatial environment, pursuing individualistic gains and using partial training on successful neighbors, randomized neural nets can learn to communicate.

This study examines whether Canadian governments have adapted budgets for the ageing population in accordance with norms of intergenerational justice. Public finance data in 2016 are analysed compared to 1976 in light of three constructs: the elderly/non-elderly ratio of social spending change, intergenerational reciprocity, and ability to pay. Findings include that governments increased per capita spending for seniors 4.2 times faster than for those under the age of 45; public finance requires younger Canadians to contribute 22%-62% more in income taxes (...) for the elderly now by comparison with 1976; and the contemporary ageing population has a greater ability to pay than cohorts immediately before and after them.

Both Carnap and Quine made significant contributions to the philosophy of mathematics despite their diversedviews. Carnap endorsed the dichotomy between analytic and synthetic knowledge and classified certainmathematical questions as internal questions appealing to logic and convention. On the contrary, Quine wasopposed to the analytic-synthetic distinction and promoted a holistic view of scientific inquiry. The purpose of thispaper is to argue that in light of the recent advancement of experimental mathematics such as Monte Carlosimulations, limiting mathematical inquiry to the domain of (...) logic is unjustified. Robustness studies implemented inMonte Carlo Studies demonstrate that mathematics is on par with other experimental-based sciences. (shrink)

This volume contains the selected discourses of four seventeenth-century philosophers, carefully chosen to illustrate the tenets characteristic of the influential movement known as Cambridge Platonism. Fundamental to their beliefs is the statement most clearly voiced by Benjamin Whichcote, their leader by common consent, that the spiritual is not opposed to the rational, nor Grace to nature. Religion is based on reason, even in the presence of 'mystery'. Free will and Grace are not mutually exclusive. The editor's comprehensive introduction delineates the (...) main principles of the Cambridge Platonists, in the light of their heritage. It compares their attitude to contemporary thought, stressing their mistrust both of institutionalised religion and of the rising tide of materialism. The sermons are reprinted from the original texts and fully annotated with comparisons and references to a wide range of works. The editor also includes a useful list for further reading, biographical notes and a comprehensive index. (shrink)

The difference in longitude between the observatories of Paris and Greenwich was long of fundamental importance to geodesy, navigation and timekeeping. Measured many times and by many different means since the seventeenth century, the preferred method of the later nineteenth and early twentieth centuries made use of the electric telegraph. I describe here for the first time the four Paris–Greenwich telegraphic longitude determinations made between 1854 and 1902. Despite contemporary faith in the new technique, the first was soon found to (...) be inaccurate; the second was a failure, ending in Anglo-French dispute over whose result was to be trusted; the third failed in exactly the same way; and when eventually the fourth was presented as a success, the evidence for that success was far from clear-cut. I use this as a case study in precision measurement, showing how mutual grounding between different measurement techniques, in the search for agreement between them, was an important force for change and improvement. I also show that better precision had more to do with the gradually improving methods of astronomical time determination than with the singular innovation of the telegraph, thus emphasizing the importance of what have been described as ‘observatory techniques’ to nineteenth-century practices of precision measurement.

Since Rose collected Petronius' ‘adaptions of Lucan’ found in the Bellum Civile, there has been renewed contention as to whether these adaptations are real or imagined, with George, Sullivan, and now Slater leading the debate.

The phrase ei mihi is used fifteen times by Plautus. On all but one occasion these words introduce a new speaker. The single ‘exception’ is, I suggest, rather an error of transmission. I quote the line in context, Bac. 1171–4 NIC. Ni abeas, quamquam tu bella es, malum tibi magnum dabo iam. BACCH. Patiar, non metuo, ne quid mihi doleat quod ferias. NIC. Ut blandiloquast! ei mihi, metuo. SOR. Hie magis tranquillust. 1173 non – blandiloquast uno versu B 1174 SOROR (...) B: B D. (shrink)

This line involves a variety of important points.

The several verbal responsions of this couplet to the preceding one are clear, and as mando produces mandata, so testor derives, I think, from testis. Read me teste ‘Idaei…’; ‘with me as witness…’. This reading adds greatly to the humour of the situation, where the hen is charged, in his presence, with caring for the fox. For testis as a witness to the audible cf. fors me sermoni testem dedit.

The scribes of the Latin poets were not, as a rule, in the habit of interpolating exclamatory particles; on the contrary, their tendency was to trivialise. The particle io has MSS authority in two passages in Ovid where distinguished critics reject it. Kenney in the Oxford Text of Ars Amatoria 3.742 prints. labor, io: cara lumina conde manu.

The recent editors, Luck , Hanslik , and Goold , allow into the text these emended instances of en.

Some time ago I noted that the generally accepted emendations a! fuge , and a! ducere are suspect , 71–2). In his recent Loeb edition , Goold in the latter passage restores the MSS. reading adducere; in the former, quisquis es assiduas aufuge blanditias, he prints Tappe's tu fuge for MSS. aufuge. The best solution, it seems to me, is one which the modern editions, Propertiana included, are of a mind to ignore: Markland's heu fuge.

To the host of suggestions I would add the sense of the passage is, ‘I have never annoyed you with petulant language, with the things the mob in the heated forum is accustomed to say, that you suffer me to… But I have often…’ His was, as line 41 explains, the language of poetry. The contrast between the language of the forum and poetry is an obvious one, and is made elsewhere by Propertius ‘turn tibi pauca suo de carmine dictat (...) Apollo et vetat insano verba tonare foro. at tu finge elegos’ . In the present passage the contrast is between the common language typical of the angry mob and the original verses of the exclusus amator. It is particularly bitter that he should be condemned to the ‘trivio’ which, like the forum, is the very milieu of the type of language he has eschewed. (shrink)

Simone Téry (1897–1967), French journalist and novelist, joined the French Communist Party in the mid-1930s after visiting the Soviet Union. She worked as a correspondent for L'Humanité, Vendredi and Regards; the latter post took her to Spain during the Civil War. The resulting texts, Front de la liberté: Espagne 1937–1938 (1938) and Où l'aube se lève (1945), form the basis of my analysis of Téry's desire to write the history of the present in inter-war France. These texts, a work of (...) reportage and a novel respectively, illustrate the relationship between the poetic, or imaginative, and the historical, or factual, in historical fiction. This relationship is particularly relevant to the literary history of 1930s France, given the highly politicized nature of literary production in the period and the resulting debates over the nature and future of the realist novel. Téry's rejection of modernism in favour of socialist realism suggests a conversion, common in left-wing writers of the period, to the notion that the modernist text is incapable of ‘containing’ history. The essay raises the question of French women writers’ relationship to committed literature in the 1930s, and demonstrates that women were active in this domain. (shrink)

An analysis of two heuristic strategies for the development of mechanistic models, illustrated with historical examples from the life sciences. In Discovering Complexity, William Bechtel and Robert Richardson examine two heuristics that guided the development of mechanistic models in the life sciences: decomposition and localization. Drawing on historical cases from disciplines including cell biology, cognitive neuroscience, and genetics, they identify a number of "choice points" that life scientists confront in developing mechanistic explanations and show how different choices result in divergent (...) explanatory models. Describing decomposition as the attempt to differentiate functional and structural components of a system and localization as the assignment of responsibility for specific functions to specific structures, Bechtel and Richardson examine the usefulness of these heuristics as well as their fallibility—the sometimes false assumption underlying them that nature is significantly decomposable and hierarchically organized. When Discovering Complexity was originally published in 1993, few philosophers of science perceived the centrality of seeking mechanisms to explain phenomena in biology, relying instead on the model of nomological explanation advanced by the logical positivists (a model Bechtel and Richardson found to be utterly inapplicable to the examples from the life sciences in their study). Since then, mechanism and mechanistic explanation have become widely discussed. In a substantive new introduction to this MIT Press edition of their book, Bechtel and Richardson examine both philosophical and scientific developments in research on mechanistic models since 1993.

Biologists studying complex causal systems typically identify some factors as causes and treat other factors as background conditions. For example, when geneticists explain biological phenomena, they often foreground genes and relegate the cellular milieu to the background. But factors in the milieu are as causally necessary as genes for the production of phenotypic traits, even traits at the molecular level such as amino acid sequences. Gene-centered biology has been criticized on the grounds that because there is parity among causes, the (...) “privileging” of genes reflects a reductionist bias, not an ontological difference. The idea that there is an ontological parity among causes is related to a philosophical puzzle identified by John Stuart Mill: what, other than our interests or biases, could possibly justify identifying some causes as the actual or operative ones, and other causes as mere background? The aim of this paper is to solve this conceptual puzzle and to explain why there is not an ontological parity among genes and the other factors. It turns out that solving this puzzle helps answer a seemingly unrelated philosophical question: what kind of causal generality matters in biology? (shrink)

Postcolonial science studies entails ostensibly contradictory critical and empirical commitments. Science studies scholars influenced by Bruno Latour and Isabelle Stengers embrace forms of realist, radical empiricism, while postcolonial studies scholars influenced by Jacques Derrida trace the limits of the knowable. This essay takes their common use of the term cosmopolitics as an unexpected point of departure for reconciling Derrida’s program with Stengers’s and Latour’s. I read Derrida’s critique of hospitality and Stengers’s and Latour’s ontological politics as necessary complements for conceiving (...) a care-oriented subalternist cosmopolitics, a process of composing common worlds that remains attentive to the limits of representation.

Bazzocchi disposes the text of the Tractatus in a user-friendly manner, exactly as Wittgenstein's decimals advise. This discloses the logical form of the book by distinct reading units, linked into a fashioned hierarchical tree. The text becomes much clearer and every reader can enjoy, finally, its formal and literary qualities.

The widespread use of stimulants among healthy individuals to improve cognition has received growing attention; however, public attitudes toward this practice are not well understood. We determined the effect of framing metaphors and context of use on public opinion toward cognitive enhancement. We recruited 3,727 participants from the United States to complete three surveys using Amazon’s Mechanical Turk between April and July 2017. Participants read vignettes describing an individual using cognitive enhancement, varying framing metaphors (fuel versus steroid), and context of (...) use (athletes versus students versus employees). The main outcome measure was the difference in respondent-assigned level of acceptability of the use of cognitive enhancement by others and by themselves between the contrasting vignettes. Participants were more likely to support the use of cognitive enhancement by others than by themselves and more when the use of enhancement by others was framed with a fuel metaphor than with a steroid metaphor. Metaphoric framing did not affect participants’ attitudes toward their own use. Participants supported the use of enhancement by employees more than by students or athletes. These results are discussed in relation to existing ethical and policy literature. (shrink)

This paper investigates the emotional import of literary devices deployed in fiction. Reflecting on the often-favored approach in the analytic tradition that locates fictional characters, events, and narratives as sources of readers’ emotions, I attempt to broaden the scope of analysis by accounting for how literary devices trigger non-cognitive emotions. I argue that giving more expansive consideration to literary devices by which authors present content facilitates a better understanding of how fiction engages emotion. In doing so, I also explore the (...) somatic dimension of reading fiction. (shrink)

This paper investigates what molecular biology has done for our understanding of the gene. I base a new account of the gene concept of classical genetics on the classical dogma that gene differences cause phenotypic differences. Although contemporary biologists often think of genes in terms of this concept, molecular biology provides a second way to understand genes. I clarify this second way by articulating a molecular gene concept. This concept unifies our understanding of the molecular basis of a wide variety (...) of phenomena, including the phenomena that classical genetics explains in terms of gene differences causing phenotypic differences.
