The chapter focusses on the Scottish natural philosophy of the late eighteenth century represented by John Anderson (1726–1796) and John Robison (1739–1805), which is considered a link between Newton’s natural philosophy and nineteenth-century physics in Britain (Kelvin and Maxwell). Anderson and Robison have to be seen in a tradition of Scottish Newtonians established in the seventeenth century by David Gregory and John Keill and specifically shaped in the Mid-eighteenth century through the chemical-physical work of Joseph Black and (...) the common-sense philosophy of Thomas Reid. These latter Newtonians built on Newton’s theory of matter and short-range forces as indicated in Query 31 of his Opticks (Black) but also on his Rules of Reasoning of the second edition of his Principia (Black and Reid) and in this way created the theoretical framework in which Anderson and Robison developed their natural philosophy. In the center of their natural philosophy, which was oriented on experimental investigations, were the manifold open questions of the Baconian sciences of that time - theories of heat, light, electricity, magnetism as well as the understanding of the phlogiston. The chapter thus provides insight into the specific way in which the Newtonian camp participated in early modern natural philosophical speculations about minute particles of matter, fluids, or the propagation of light and heat.

In Dirac-Bergmann constrained dynamics, a first-class constraint typically does not _alone_ generate a gauge transformation. By direct calculation it is found that each first-class constraint in Maxwell's theory generates a change in the electric field E by an arbitrary gradient, spoiling Gauss's law. The secondary first-class constraint p^i,_i=0 still holds, but being a function of derivatives of momenta, it is not directly about E. Only a special combination of the two first-class constraints, the Anderson-Bergmann -Castellani gauge generator G, (...) leaves E unchanged. This problem is avoided if one uses a first-class constraint as the generator of a _canonical transformation_; but that partly strips the canonical coordinates of physical meaning as electromagnetic potentials and makes the electric field depend on the smearing function, bad behavior illustrating the wisdom of the Anderson-Bergmann Lagrangian orientation of interesting canonical transformations. The need to keep gauge-invariant the relation dot{q}- dH/dp= -E_i -p^i=0 supports using the primary Hamiltonian rather than the extended Hamiltonian. The results extend the Lagrangian-oriented reforms of Castellani, Sugano, Pons, Salisbury, Shepley, _etc._ by showing the inequivalence of the extended Hamiltonian to the primary Hamiltonian even for _observables_, properly construed in the sense implying empirical equivalence. Dirac and others have noticed the arbitrary velocities multiplying the primary constraints outside the canonical Hamiltonian while apparently overlooking the corresponding arbitrary coordinates multiplying the secondary constraints _inside_ the canonical Hamiltonian, and so wrongly ascribed the gauge quality to the primaries alone, not the primary-secondary team G. Hence the Dirac conjecture about secondary first-class constraints rests upon a false presupposition. The usual concept of Dirac observables should also be modified to employ the gauge generator G, not the first-class constraints separately, so that the Hamiltonian observables become equivalent to the Lagrangian ones such as the electromagnetic field F.

We say that a real X is n-generic relative to a perfect tree T if X is a path through T and for all $\Sigma _{n}^{0}(T)$ sets S, there exists a number k such that either X|k ∈ S or for all σ ∈ T extending X|k we have σ ∉ S. A real X is n-generic relative to some perfect tree if there exists such a T. We first show that for every number n all but countably many reals (...) are n-generic relative to some perfect tree. Second, we show that proving this statement requires ZFC− + "∃ infinitely many iterates of the power set of ω". Third, we prove that every finite iterate of the hyperjump. ${\cal O}^{(n)}$ , is not 2-generic relative to any perfect tree and for every ordinal α below the least λ such that supβ<i (βth admissible) = λ, the iterated hyperjump ${\cal O}^{(\alpha)}$ is not 5-generic relative to any perfect tree. Finally, we demonstrate some necessary conditions for reals to be 1-generic relative to some perfect tree. (shrink)

This article is an introduction to two other articles in this issue, Catherine Maxwell’s ‘Teaching 19th-century aesthetic prose’ and Kirsteen Anderson’s ‘The whole learner: the role of imagination in developing disciplinary learning’. It highlights the significance of the courses described in Maxwell’s and Anderson’s accounts by discussing how the writing tasks that they engage students in contribute to the development of disciplinary understanding, and how, whilst eschewing reliance on the conventional schooled essay, they enable students to (...) develop writing that is essayistic. It points to the potential that reinvisaging disciplinary writing has for curriculum and assessment design. (shrink)

Life history theory predicts that greater extrinsic mortality will lead to earlier and higher fertility. To test this prediction, I examine the relationship between life expectancy at birth and several proxies for life history traits (ages at first sex and first marriage, total fertility rate, and ideal number of children), measured for both men and women. Data on sexual behaviors come from the Demographic and Health Surveys (DHS). Two separate samples are analyzed: a cross-sectional sample of 62 countries and a (...) panel sample that includes multiple cross-sectional panels from 48 countries. Multivariate regression analysis is used to control for potential confounding variables. The results provide only partial support for the predictions, with greater support among women than men. However, the prediction is not supported in sub-Saharan African countries, most likely owing to the nonequilibrium conditions observed in sub-Saharan Africa with respect to life expectancy. The applicability of the model to understanding HIV/AIDS risk behaviors is discussed. (shrink)

O artigo que ora apresentamos problematiza a formação e os enfrentamentos da Associação Liberdades Poéticas para atender ao Objetivo Número 16 da ONU, “Paz, Justiça e Instituições Eficazes”. Trata-se de um grupo de voluntários, composto por pessoas de diferentes sexualidades, formações acadêmicas, atuações profissionais e faixas etárias, criado em 2020 durante a pandemia, que tem como premissa reconhecer a prática da leitura como um Direito Humano, indispensável à humanização e à transformação dos sujeitos. Atuamos com remição de pena por leitura (...) no sistema prisional paulista, que confere, às pessoas privadas de liberdade, quatro dias de redução na sentença para cada obra lida, em um limite de dez títulos/ano. Nossa fundamentação teórica sustenta-se em Antonio Candido, em Lynn Hunt, no Conselho Nacional de Justiça (CNJ), na Constituição Federal, entre outros. Concluímos que, apesar da orientação geral da ONU e dos esforços do governo federal com a publicação da Resolução 391/2021, do Conselho Nacional de Justiça, para flexibilizar a remição de pena por meio da leitura, agentes do sistema penitenciário no estado de São Paulo ainda operam sob uma lógica autoritária que não corresponde à do CNJ, tampouco à ODS 16.

The meaning of the once widely used term the Gibbs Free Energy in terms of available work energy is perfectly illustrated for chemical reactions by the Van’t Hoff Equilibrium Box. Combining this with DeDonder’s extent of reaction variable and using the reaction of $$\hbox {NH}_3$$ to $$\hbox {H}_2$$ and $$\hbox {N}_2$$ at $$200^{\circ }\hbox {C}$$ as an example shows the difference between total work energy and available work energy, and in addition allows calculation of the equilibrium composition, demonstration of the (...) minimum in the Gibbs energy curve, and the standard relationship between $$\Delta _\textrm{r}G^{\circ }$$ and $$\ln {K}$$.

Reading fiction for pleasurable is robustly correlated with improved cognitive attainment and other benefits. It is also in decline among young people in developed nations, in part because of competition from moving image fiction. We review existing research on the differences between reading/hearing verbal fiction and watching moving image fiction, as well as looking more broadly at research on image/text interactions and visual versus verbal processing. We conclude that verbal narrative generates more diverse responses than moving image narrative., We note (...) that reading and viewing narrative are different tasks, with different cognitive loads. Viewing moving image narrative mostly involves visual processing with some working memory engagement, whereas reading narrative involves verbal processing, visual imagery and personal memory (Xu et al 2005). but Attempts to compare the two by creating suggest that existing research is flawed by attempts to create equivalent stimuli and task demands face a number of challenges, and we discuss these difficulties in comparative approaches. We then investigate the possibility of identifying lower level processing mechanisms that might distinguish cognition of the two media, and propose a focus on internal scene construction and on working memory as foci for future research. Although many of the sources we draw on are focussed on English speaking participants in European or North American settings, we also cover material relating to speakers of Dutch, German, Hebrew and Japanese in their respective countries, and studies of a remote Turkish mountain community.

The axiomatic bases of Special Relativity Theory (SRT) are thoroughly re-examined from an operational point of view, with particular emphasis on the status of Einstein synchronization in the light of the possibility of arbitrary synchronization procedures in inertial reference frames. Once correctly and explicitly phrased, the principles of SRT allow for a wide range of “theories” that differ from the standard SRT only for the difference in the chosen synchronization procedures, but are wholly equivalent to SRT in predicting empirical facts. (...) This results in the introduction, in the full background of SRT, of a suitable synchronization gauge. A complete hierarchy of synchronization gauges is introduced and elucidated, ranging from the useful Selleri synchronization gauge (which should lead, according to Selleri, to a multiplicity of theories alternative to SRT) to the more general Mansouri–Sexl synchronization gauge and, finally, to the even more general Anderson–Vetharaniam–Stedman’s synchronization gauge. It is showed that all these gauges do not challenge the SRT, as claimed by Selleri, but simply lead to a number of formalisms which leave the geometrical structure of Minkowski spacetime unchanged. Several aspects of fundamental and applied interest related to the conventional aspect of the synchronization choice are discussed, encompassing the issue of the one-way velocity of light in inertial and rotating reference frames, the global positioning system (GPS)’s working, and the recasting of Maxwell equations in generic synchronizations. Finally, it is showed how the gauge freedom introduced in SRT can be exploited in order to give a clear explanation of the Sagnac effect for counter-propagating matter beams. (shrink)

The generation of value bubbles is an inherently psychological and social process, where information sharing and individual decisions can affect representations of value. Bubbles occur in many domains, from the stock market, to the runway, to the laboratories of science. Here we seek to understand how psychological and social processes lead representations (i.e., expectations) of value to become divorced from the inherent value, using asset bubbles as an example. We hypothesize that simple asset group switching rules can give rise to (...) aggregate behavior that resembles the irrational exuberance that can drive asset bubbles. Using an agent-based model we explore whether a simple switching rule can generate irrational exuberance, and systematically explore how communication between decision makers influences the speed and intensity of overvaluation. We show that rational and simple individual level rules combined with honest information sharing are sufficient to generate the collective overvaluation characteristic of irrational exuberance. Further, our results demonstrate that low fidelity in the exchange of value information leads to rapidly increasing expectations about value, even when no one is engaged in exaggerating their expectations for the assets they own.

Kant says that it was "the objection of David Hume that first...interrupted my dogmatic slumber"; he also says that "it was the fourfold Antinomy...that first woke me from dogmatic slumber." These statements raise a serious problem: how can the Critique of Pure Reason be at once a response to Hume's skepticism and the result of the Antinomy, which attacks dogmatic metaphysics? Hume's Attack on Theology and the Origin of Kant's Antinomy resolves this problem by showing that the Antinomy is the (...) product of Hume's skepticism, whose primary target is metaphysics and theology. Hume in the Enquiry hints that Clarke's Demonstration issues in an antithetic. Both the dogmatic theism of Clarke and the dogmatic materialism of his opponents, Hume indicates, were underwritten by the principle that nothing comes from nothing. This hint inspired Kant's conception of the Antinomy as a conflict between rival applications of the rationalist principle of sufficient reason (psr). Hume's Dialogues led Kant in the Critique to embrace Hume's conception of Clarke's Demonstration as an antithetic, to interpret that antithetic as an antinomy, and to resolve that antinomy by denying that we are entitled to the psr. Like Hume's Enquiry and Dialogues and Rousseau's Émile, the Critique is part of the battle for Enlightenment, the struggle against the 'despotic' reign of theological dogmatism. The victory of philosophy in this battle has made this hard to see; Hume and the Origin of Kant's Antinomy aims to bring it back into view. (shrink)

In 1941 Fritz Saxl and Rudolf Wittkower of the Warburg Institute organized an exhibition on English Art and the Mediterranean. The photographic exhibition showed the long history of artistic and cultural ties between English art and the classical tradition, employing Aby Warburg's method. The project was an attempt by Saxl, as director, to show the relevance of the Warburg Institute's work in England, the new home of the Library since 1933. Kenneth Clark, director of the National Gallery, actively promoted the (...) work of the Institute, including by supporting the naturalization process for many of the Warburg scholars. The popular belief in the cultural ties between England and Italy fed into the positive reception for the exhibition and into acceptance of the work of the Warburg Institute. The exhibition was published in a large format catalog in 1948, further adding to the popularity of the exhibition with a diverse British public. Although the motivation for the exhibition emerged from political conditions and institutional circumstance, it had a lasting effect on the history of the study of English art and architecture. Wittkower and others turned to research on the classical tradition in English art, even though the method had limited relevance beyond the “neoclassical” period. (shrink)

Maintaining adequate performance in dynamic and uncertain settings has been a perennial stumbling block for intelligent systems. Nevertheless, any system intended for real-world deployment must be able to accommodate unexpected change—that is, it must be perturbation tolerant. We have found that metacognitive monitoring and control—the ability of a system to self-monitor its own decision-making processes and ongoing performance, and to make targeted changes to its beliefs and action-determining components—can play an important role in helping intelligent systems cope with the perturbations (...) that are the inevitable result of real-world deployment. In this article we present the results of several experiments demonstrating the efficacy of metacognition in improving the perturbation tolerance of reinforcement learners, and discuss a general theory of metacognitive monitoring and control, in a form we call the metacognitive loop.

For many decades, race and racism have been common areas of study in departments of sociology, history, political science, English, and anthropology. Much more recently, as the historical concept of race and racial categories have faced significant scientific and political challenges, philosophers have become more interested in these areas. This changing understanding of the ontology of race has invited inquiry from researchers in moral philosophy, metaphysics, epistemology, philosophy of science, philosophy of language, and aesthetics. The Routledge Companion to Philosophy of (...) Race offers in one comprehensive volume newly written articles on race from the world's leading analytic and continental philosophers. It is, however, accessible to a readership beyond philosophy as well, providing a cohesive reference for a wide student and academic readership. The Companion synthesizes current philosophical understandings of race, providing 37 chapters on the history of philosophy and race as well as how race might be investigated in the usual frameworks of contemporary philosophy. The volume concludes with a section on philosophical approaches to some topics with broad interest outside of philosophy, like colonialism, affirmative action, eugenics, immigration, race and disability, and post-racialism. By clearly explaining and carefully organizing the leading current philosophical thinking on race, this timely collection will help define the subject and bring renewed understanding of race to students and researchers in the humanities, social science, and sciences.

A functional theory of memory has already been developed as part of a general functional theory of cognition. The traditional conception of memory as “reproductive” touches on only a minor function. The primary function of memory is in constructing values for goal-directedness of everyday thought and action. This functional approach to memory rests on a solid empirical foundation.

In the past decade there has been a lot of attention to the quality of the evidence in experimental psychology and in other social and medical sciences. Some have described the current climate as a ‘crisis of confidence’. We focus on a specific question: how can we increase the quality of the data in psychology and cognitive neuroscience laboratories. Again, the challenges of the field are related to many different issues, but we believe that increasing the quality of the data (...) collection process and the quality of the data per se will be a significant step in the right direction. We suggest that the adoption of quality control systems which parallel the methods used in industrial laboratories might be a way to improve the quality of data. We recommend that administrators incentivize the use of quality systems in academic laboratories. (shrink)

Plotinus, the father of Neoplatonism, lived in Rome during the third century AD. For many scholars -- not only classicists and philosophers but medievalists, renaissance specialists, Islamists, theologians, and students of religion -- he remains a figure.

What characterizes emergency today is the proliferation of the term. Any event or situation supposedly has the potential to become an emergency. Emergencies may happen anywhere and at any time. They are not contained within one functional sector or one domain of life. The substantive focus of the articles collected in this special issue reflects this proliferation: they explore ways of governing in, by and through emergencies across different types of emergencies and different domains of life. In response to this (...) proliferation, the issue opens up critical work on the politics of emergency beyond the ‘state of exception’ as dominant paradigm. Emergency is treated as a problem for government that calls for the invention of new techniques or the redeployment of existing techniques. Through this shift in emphasis, the articles in this issue disclose relations between modalities of power and emergency life that differ from the ‘lightening flash’ of a sovereign decision on the exception taken from outside of life, or the capacity to ‘mould’ an always-already emergent life from within life.

For decades questionnaires have been used to measure the cognitive and psychological effects of prenatal genetic testing, but little is known about why some women undergo testing and others decline. Research indicates that many factors influence decision making, including values and beliefs. What is often denied rather than recognized is that the professional and personal values and beliefs held by the health care provider influence the patient’s decision. It is assumed that, if genetic services are delivered in a nondirective manner, (...) patients will not be affected by the provider’s personal and professional standpoint. The qualitative research data reported here challenge this assumption. Getting to know patients’ moral understanding and patterns of ethical reasoning by listening to their personal stories is recommended as a better way for nurses to help patients to make informed and autonomous decisions about prenatal genetic screening or diagnostic tests.
