Galvanic vestibular stimulation is a non-invasive method of electrically stimulating the vestibular system. We investigated whether the application of GVS can alter the learning of new functional mobility and manual control tasks and whether learning can be retained following GVS application. In a between-subjects experiment design, 36 healthy subjects performed repeated trials, capturing the learning of either a functional mobility task, navigating an obstacle course on a compliant surface with degraded visual cues or a manual control task, using a joystick (...) to null self-roll tilt against a pseudo-random disturbance while seated in the dark. In the “learning” phase of trials, bilateral, bipolar GVS was applied continuously. The GVS waveform also differed between subjects in each task group: white noisy galvanic vestibular stimulation at 0.3 mA high-level random GVS at 0.7 mA, or with the absence of stimulation. Following the “learning” trials, all subjects were blindly transitioned to sham GVS, upon which they immediately completed another series of trials to assess any aftereffects. In the functional mobility task, we found nGVS significantly improved task learning. Further, improvements in learning the functional mobility task with nGVS were retained, even once the GVS application was stopped. The benefits in learning with nGVS were not observed in the manual control task. High level GVS tended to inhibit learning in both tasks, but not significantly so. Even once the high-level stimulation was stopped, the impaired performance remained. Improvements in learning with nGVS may be due to increased information throughput resulting from stochastic resonance. The benefit of nGVS for functional mobility, but not manual control nulling, may be due to the multisensory, strategic, motor coordination, or spatial awareness aspects of the former task. Learning improvements with nGVS have the potential to benefit individuals who perform functional mobility tasks, such as astronauts, firefighters, high performance athletes, and soldiers. (shrink)

Each paper is followed by a response from Scheffler himself. (...) The collection is essential reading for anyone concerned with contemporary scholarship in philosophy of education, or with the place of this singularly important author in it. (shrink)

Background: In recent decades, the amount of research on social and emotional learning programs in schools has increased significantly, showing a great number of positive student outcomes, including greater ability to perceive, understand and manage emotions, better attitudes about self and others, less aggressive and/or disruptive behavior, higher levels of psychological well-being and improvement in academic performance among others. The purpose of this research was the design and implementation of the OKAPI emotional education program. A multidimensional program based on cooperative (...) learning methodology. Methods: 86 students of Primary Education, from 3rd to 5th grade (45 students in the experimental unit and 41 in the control group). Results: The implementation of the OKAPI has a positive impact in academic achievement. Conclusion: This program shows the convenience of incorporating programs that can be integrated into the school life and can be applied by the teaching staff using both social emotional learning and school climate approaches.

The purpose of this paper is to provide a new system of logic for existence and essence, in which the traditional distinctions between essential and accidental properties, abstract and concrete objects, and actually existent and possibly existent objects are described and related in a suitable way. In order to accomplish this task, a primitive relation of essential identity between different objects is introduced and connected to a first order existence property and a first order abstractness property. The basic idea is (...) that possibly existent objects are completely determinate and that essentially identical objects are just different individuations of the same individual essence. Accordingly, essential properties are defined as properties that are invariant with respect to this kind of identity, while abstract objects are determined by being characterized by essential properties only. Once such ideas are implemented, a number of classical intuitions about objects, their essence, and their way of existence can be consistently interpreted. (shrink)

In Cabo Delgado, Mozambique, the year of 2020 marked a dramatic escalation of military activities of the Islamist insurgent group locally known as Al-Shabab or mashababe. This intensification was accompanied by a more immaterial phenomenon: the rise in prominence of social media, both as battleground and as public forum. While the insurgents sacked and occupied major towns and district headquarters, the Web 2.0 networks - Facebook and WhatsApp especially - became the central arena in which the war was apprehended and (...) discussed. This essay is an exploration of the entwining of social media with the 'new war' in Cabo Delgado, focussing on the events that surround the conquest of the Makonde plateau, mythical cradle of the Mozambican liberation struggle. Building on a budding literature on digital militarism, the essay dwells especially on orality and the use of the voice note as a medium to convey information deemed to be more trustworthy and stable than images. Tracking these media and their interrelations, the essay establishes a narrative, however fragmentary, of the downfall of the Makonde plateau; highlights recurring features of violence in the Cabo Delgado conflict; and provides fresh insight into the formation of the Local Force (Força Local), a State-sponsored militia largely constituted by war veterans.

The debate that raged in the interwar period between the Austrian economists and socialist economists was, narrowly conceived, a debate in positive economics. What was being discussed was certainly not the morality of capitalism or of socialism. Nor, strictly speaking, was the debate even about society's economic well-being under socialism; it concerned the ability of central planners to make decisions that take appropriate account of relevant resource scarcities, in the light of consumer preference rankings. To be sure, the extraordinary interest (...) which surrounded the debate and the passions that lurked barely below its surface testified to the powerful implications of the debate for crucial issues in welfare economics. The Austrians were not merely exploring the economies of socialism; they were in effect demonstrating that, as an economic system attempting to serve the needs of its citizens, socialism must inevitably fail. But, even if the debate is interpreted in its broadest terms, as a debate in welfare economics, it represented a sharp break widi traditional polemics relating to the socialism-capitalism issue. Traditionally the arguments for or against capitalism had, until 1920, been deeply involved in ediical questions. Mises's 1920 challenge to socialism, in contrast, was explicit in making no attempt to address any claims concerning the alleged moral superiority of socialism. He simply argued that, as an economic system, socialism was inherendy incapable of fulfilling the objectives of its proponents; central planners are unable to plan centrally. (shrink)

In the wake of the Scientific Revolution, the late seventeenth and eighteenth centuries saw the complete demolition of traditional structures of authority, scientific thought, and belief by the new philosophy and the philosophes, including Voltaire, Diderot, and Rousseau. The Radical Enlightenment played a part in this revolutionary process, which effectively overthrew all justification for monarchy, aristocracy, and ecclesiastical power, as well as man's dominance over woman, theological dominance of education, and slavery. Despite the present day interest in the revolutions of (...) the eighteenth century, the origins and rise of the Radical Enlightenment have received limited scholarly attention. The greatest obstacle to the movement finding its proper place in modern historical writing is its international scope: the Racial Enlightenment was not French, British, German, Italian, Jewish or Dutch, but all of these at the same time. In this wide-ranging volume, Jonathan Israel offers a novel interpretation of the Radical Enlightenment down to La Mettie and Diderot, two of its key exponents. Particular emphasis is placed on the pivotal role of Spinoza and the widespread underground international philosophical movement known before 1750 as Spinozism. (shrink)

The first major reassessment of the Western Enlightenment for a generation. Continuing the story he began in Radical Enlightenment, Jonathan Israel now focuses on the first half of the eighteenth century. He traces to their roots the core principles of Western modernity: the primacy of reason, democracy, racial equality, feminism, religious toleration, sexual emancipation, and freedom of expression.

Brutus wanted to kill Caesar. He believed that Caesar was an ordinary mortal, and that, given this, stabbing him (by which we mean plunging a knife into his heart) was a way of killing him. He thought that he could stab Caesar, for he remembered that he had a knife and saw that Caesar was standing next to him on his left, in the Forum. So Brutus was motivated to stab the man to his left. He did so, thereby killing (...) Caesar. (shrink)

An Introduction to Proof Theory provides an accessible introduction to the theory of proofs, with details of proofs worked out and examples and exercises to aid the reader's understanding. It also serves as a companion to reading the original pathbreaking articles by Gerhard Gentzen. The first half covers topics in structural proof theory, including the Gödel-Gentzen translation of classical into intuitionistic logic, natural deduction and the normalization theorems, the sequent calculus, including cut-elimination and mid-sequent theorems, and various applications of these (...) results. The second half examines ordinal proof theory, specifically Gentzen's consistency proof for first-order Peano Arithmetic. The theory of ordinal notations and other elements of ordinal theory are developed from scratch, and no knowledge of set theory is presumed. The proof methods needed to establish proof-theoretic results, especially proof by induction, are introduced in stages throughout the text. Mancosu, Galvan, and Zach's introduction will provide a solid foundation for those looking to understand this central area of mathematical logic and the philosophy of mathematics. (shrink)

The aim of this essay is twofold. First, it outlines the concept of ontological frame. Secondly, two models are distinguished on this structure. The first one is connected to Kant’s concept of possible object and the second one relates to Leibniz’s. Leibniz maintains that the source of possibility is the mere logical consistency of the notions involved, so that possibility coincides with analytical possibility. Kant, instead, argues that consistency is only a necessary component of possibility. According to Kant, something is (...) possible if there is a cause capable of bringing it into existence; to this end consistency alone is not sufficient. Thus, while the Leibnizian notion of consistency is at the root of the concept of analytical possibility, the Kantian notion of possibility is the source of real possibility. This difference plays an important role in the discussion of Gödel’s ontological proof, which can be formally interpreted on the ontological frame of the pure perfections. While this proof, under some emendation condition, is conclusive in the context of Leibniz’s ontological model, it is not so within the Kantian one. This issue will be the subject of the second part of the present essay. (shrink)

Mechanisms occurring at the atomic level are now known to drive processes essential for life, as revealed by quantum effects on biochemical reactions. Some macroscopic characteristics of organisms may thus show an atomic imprint, which may be transferred across organisms and affect their evolution. This possibility is considered here for the first time, with the aim of elucidating the appearance of an animal innovation with an unclear evolutionary origin: migratory behaviour. This trait may be mediated by a radical pair (RP) (...) mechanism in the retinal flavoprotein cryptochrome, providing essential magnetic orientation for migration. Isotopes may affect the performance of quantum processes through their nuclear spin. Here, we consider a simple model and then apply the standard open quantum system approach to the spin dynamics of cryptochrome RP. We changed the spin quantum number (I) and g‐factor of hydrogen and nitrogen isotopes to investigate their effect on RP's yield and magnetic sensitivity. Strong differences arose between isotopes with I = 1 and I = 1/2 in their contribution to cryptochrome magnetic sensitivity, particularly regarding Earth's magnetic field strengths (25–65 µT). In most cases, isotopic substitution improved RP's magnetic sensitivity. Migratory behaviour may thus have been favoured in animals with certain isotopic compositions of cryptochrome. (shrink)

In the following article, I introduce three forms of spirituality elucidated by Santayana in his Reason in Religion, viz. the Fanatical, the Rational, and the Mystical. First, I explore what kinds of spiritual practices and ideologies are considered fanatical or devoted to escaping worldliness via establishing a single, essentially arbitrary, interest. Second, I explore what kinds of spiritual practices and ideologies are considered mystical or devoted to escaping worldliness via abstention and surrender. Third, I explore what kinds of spiritual practices (...) and ideologies are considered rational or devoted to escaping worldliness via seeking “a rational advance over it”. Finally, I use these forms to demonstrate the unity between Santayana’s earlier works with his later works, to clarify Santayana’s notion of a Union with The Good, and to explore similarities and differences between the Life of Reason and Realms of Being.

In this article I defend a form of classical possibilism with an actualist foundation. As a matter of fact, I believe that this position is more in keeping with the classical metaphysical tradition. According to this form of possibilism, I construe possible objects as possible non-existing objects of an existing producing power. Consequently, they are nothing vis-à -vis the modality of their own actual being, although they do exist with regard to the modality of the producing power’s being. The actualist (...) requirement prescribed by the Frege-Quinean criterion of the quantification domain is thus fulfilled; indeed, really possible objects are not actual objects, but their possibility is actual.

Three decades ago, interactions between evolutionary biology and physiology gave rise to evolutionary physiology. This caused comparative physiologists to improve their research methods by incorporating evolutionary thinking. Simultaneously, evolutionary biologists began focusing more on physiological mechanisms that may help to explain constraints on and trade‐offs during microevolutionary processes, as well as macroevolutionary patterns in physiological diversity. Here we argue that evolutionary physiology has yet to reach its full potential, and propose new avenues that may lead to unexpected advances. Viewing physiological (...) adaptations in wild animals as potential solutions to human diseases offers enormous possibilities for biomedicine. New evidence of epigenetic modifications as mechanisms of phenotypic plasticity that regulate physiological traits may also arise in coming years, which may also represent an overlooked enhancer of adaptation via natural selection to explain physiological evolution. Synergistic interactions at these intersections and other areas will lead to a novel understanding of organismal biology. (shrink)

First published in 1963, this title considers the philosophical problems encountered when attempting to provide a clear and general explanation of scientific principles, and the basic confrontation between such principles and experience. Beginning with a detailed introduction that considers various approaches to the philosophy and theory of science, Israel Scheffler then divides his study into three key sections – Explanation, Significance and Confirmation – that explore how these complex issues involved have been dealt with in contemporary research. This title, (...) by one of America’s leading philosophers, will provide a valuable analysis of the theory and problems surrounding the Philosophy of Science. (shrink)

Objectivity Under Attack: a fundamental feature of science is its ideal of objectivity, an ideal that subjects ...

The concept of potential plays a prominent role in the thinking of parents, educators and planners the world over. Although this concept accurately reflects central features of human nature, its current use perpetuates traditional myths of fixity, harmony and value, calculated to cause untold mischief in social and educational practice. First published in 1985, Israel Scheffler's book aims to demythologise the concept of potential. He shows its roots in genuine aspects of human nature, but at the same time frees (...) it from outworn philosophical myths by means of analytical reconstruction - thereby improving both its theoretical and its practical applicability. The book concludes with an interpretation of policy-making in education, and reflections on the ideal education of a policy-maker. It emphasises human symbolism, choice, temporal continuity, and self-determination as indispensible elements of any adequate philosophy of education. _Of Human Potential _will be of interest to a broad range of philosophers, educators and social scientists.

Jean-Luc Nancy is a prolific thinker, not only because of an abundant body of work—more than a hundred titles—but also and above all because his thought, in the form of an opening, encourages and invites us to think what he himself has not put into question. So it is with the category of “milieu”. This category, of which Georges Canguilhem in his time marked the contemporaneity, is more relevant today than ever. It enables us to think differently about our world, (...) and about what makes the world our world. Who makes the “we,” when we think through the “milieu”? How can we think from the relationship first and not from a primordial subject? How, therefore, can we think of another subjectivity, beyond the reflexive subjectivity of the human? This study aims to show the conditions in which Nancy’s work can contribute in a powerful way to a thought of being-together from an ecosophical point of view. (shrink)

In recent years numerous attempts have been made by analytic philosophers to naturalize various different domains of philosophical inquiry. All of these attempts have had the common goal of rendering these areas of philosophy amenable to empirical methods, with the intention of securing for them the supposedly objective status and broad intellectual appeal currently associated with such approaches. This volume brings together internationally recognised analytic philosophers, including Alvin Plantinga, Peter van Inwagen and Robert Audi, to question the project of naturalism. (...) The articles investigate what it means to naturalize a domain of philosophical inquiry and look at how this applies to the various sub-disciplines of philosophy including epistemology, metaphysics and the philosophy of the mind. The issue of whether naturalism is desirable is raised and the contributors take seriously the possibility that excellent analytic philosophy can be undertaken without naturalization. Controversial and thought-provoking, Analytic Philosophy Without Naturalism examines interesting and contentious methodological issues in analytic philosophy and explores the connections between philosophy and science.

That the Enlightenment shaped modernity is uncontested. Yet remarkably few historians or philosophers have attempted to trace the process of ideas from the political and social turmoil of the late eighteenth century to the present day. This is precisely what Jonathan Israel now does. In Democratic Enlightenment , Israel demonstrates that the Enlightenment was an essentially revolutionary process, driven by philosophical debate. The American Revolution and its concerns certainly acted as a major factor in the intellectual ferment that (...) shaped the wider upheaval that followed, but the radical philosophes were no less critical than enthusiastic about the American model. From 1789, the General Revolution's impetus came from a small group of philosophe-revolutionnaires , men such as Mirabeau, Sieyes, Condorcet, Volney, Roederer, and Brissot. Not aligned to any of the social groups represented in the French National assembly, they nonetheless forged " la philosophie moderne "--in effect Radical Enlightenment ideas--into a world-transforming ideology that had a lasting impact in Latin America, Canada and eastern Europe as well as France, Italy, Germany, and the Low Countries. In addition, Israel argues that while all French revolutionary journals powerfully affirmed that la philosophie moderne was the main cause of the French Revolution, the main stream of historical thought has failed to grasp what this implies. Israel sets the record straight, demonstrating the true nature of the engine that drove the Revolution, and the intimate links between the radical wing of the Enlightenment and the anti-Robespierriste "Revolution of reason." Acclaim for earlier volumes in the trilogy: "His vast--and vastly impressive--book sets out to redefine the intellectual landscape of early modern Europe. Magnificent and magisterialwill undoubtedly be one of the truly great historical works of the decade." -- Sunday Telegraph "The scholarship is breathtaking. Israel has read everything, absorbed every nuance, followed up every byway." -- New Statesman "An enormously impressive piece of scholarship. The breadth and depth of the author's reading are breathtaking and Enlightenment Contested is set to become the definitive work for philosophers as well as historians on this extraordinary period." -- Tribune.
