Israel Scheffler is the pre-eminent philosopher of education in the English-speaking world today. This volume collects seventeen original, invited papers on Scheffler's philosophy of education by scholars from around the world. The papers address the wide range of topics that Scheffler's work in philosophy of education has addressed, including the aims of education, cognition and emotion, teaching, the language of education, science education, moral education, religious education, and human potential. 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)

The paper studies two formal schemes related to -completeness.LetS be a suitable formal theory containing primitive recursive arithmetic and letT be a formal extension ofS. Denoted by (a), (b) and (c), respectively, are the following three propositions (where (x) is a formula with the only free variable x): (a) (for anyn) ( T (n)), (b) T x Pr T (–(x)–) and (c) T x(x) (the notational conventions are those of Smoryski [3]). The aim of this paper is to examine the (...) meaning of the schemes which result from the formalizations, over the base theoryS, of the implications (b) (c) and (a) (b), where ranges over all formulae. The analysis yields two results overS : 1. the schema corresponding to (b) (c) is equivalent to ¬Cons T and 2. the schema corresponding to (a) (b) is not consistent with 1-CON T. The former result follows from a simple adaptation of the -incompleteness proof; the second is new and is based on a particular application of the diagonalization lemma. (shrink)

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)

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)

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)

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)

Bohmian mechanics represents the universe as a set of paths with a probability measure defined on it. The way in which a mathematical model of this kind can explain the observed phenomena of the universe is examined in general. It is shown that the explanation does not make use of the full probability measure, but rather of a suitable set function deriving from it, which defines relative typicality between single-time cylinder sets. Such a set function can also be derived directly (...) from the standard quantum formalism, without the need of an underlying probability measure. The key concept for this derivation is the quantum typicality rule, which can be considered as a generalization of the Born rule. The result is a new formulation of quantum mechanics, in which particles follow definite trajectories, but which is based only on the standard formalism of quantum mechanics. (shrink)

O objetivo deste artigo é refletir sobre os conceitos de verdadeiro e falso self e sua manifestação na clínica contemporânea; bem como as possibilidades de intervenção a partir da psicanálise winnicottiana. O conceito de falso self proposto por Winnicott é de grande valia para se pensar nos relatos ..

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)

A major intellectual history of the American Revolution and its influence on later revolutions in Europe and the Americas The Expanding Blaze is a sweeping history of how the American Revolution inspired revolutions throughout Europe and the Atlantic world in the eighteenth and nineteenth centuries. Jonathan Israel, one of the world’s leading historians of the Enlightenment, shows how the radical ideas of American founders such as Paine, Jefferson, Franklin, Madison, and Monroe set the pattern for democratic revolutions, movements, and (...) constitutions in France, Britain, Ireland, the Netherlands, Belgium, Poland, Greece, Canada, Haiti, Brazil, and Spanish America. The Expanding Blaze reminds us that the American Revolution was an astonishingly radical event—and that it didn’t end with the transformation and independence of America. Rather, the Revolution continued to reverberate in Europe and the Americas for the next three-quarters of a century. This comprehensive history of the Revolution’s international influence traces how American efforts to implement Radical Enlightenment ideas—including the destruction of the old regime and the promotion of democratic republicanism, self-government, and liberty—helped drive revolutions abroad, as foreign leaders explicitly followed the American example and espoused American democratic values. The first major new intellectual history of the age of democratic revolution in decades, The Expanding Blaze returns the American Revolution to its global context. (shrink)

Israel Gottlieb Canz’ im Jahre 1742 erschienene Theologia naturalis thetico-polemica ist die erste von drei Abhandlungen dieses Autors über natürliche Theologie. Diese ist bei ihm als eine Art Vorbereitung für die „theologia sublimior“ (die geoffenbarte Theologie) zu verstehen. Die Theologia naturalis hat bei Canz als eine theologia thetica eine darlegende und beweisende Funktion. Dahinter steht eine programmatische These, nämlich dass sie als alleinige Erlöserin des Menschen von seinen Sünden nicht ausreicht. Vielmehr soll durch sie die Notwendigkeit des Weges zur (...) Versöhnung aufgezeigt werden; den Weg selber zu erforschen steht ihr nicht zu. Canz’ natürliche Theologie ist auch eine theologia polemica. Gleich in der Praefatio präzisiert der Verfasser, dass er die Systeme der Gegner, ihre Argumente usw. darlegen und sie analysieren und diskutieren werde. Dies erfolgt aber im Hinblick auf den eigenen Diskurs bzw. im Ausgang von diesem, der sich in Konformität mit der geoffenbarten Theologie weiß. Canz gehört zur ersten Generation „Wolffscher Theologen“, bewahrt sich aber eine gewisse Unabhängigkeit gegenüber Topoi der Wolffschen Philosophie und geht durchaus eigene Wege. Dies im Einzelnen nachzuweisen, gehört zu den zahlreichen Forschungsdesideraten im Hinblick auf die Philosophie des 18. Jahrhunderts. Israel Gottlieb Canz’s Theologia naturalis thetico-polemica, published in 1742 is the first of three works by this author on natural theology, which in his case should be understood as a kind of preparation for the ‘theologia sublimior’ (revealed theology). In Canz’s work, theologia naturalis has the expository and substantiating function of a theologia thetica. Behind this stands a programmatic thesis, namely that theology alone is not sufficient to redeem mankind from its sins. Instead, the necessity of a path to reconciliation must be demonstrated; it is not the role of theology itself to seek that path. Canz’s natural theology is also a theologia polemica. In the preface the author states that he will explain, analyse and discuss his opponents’ systems, arguments etc. However, he does this with reference to his own discourse, or rather taking that discourse, which is recognised as conforming with revealed theology, as a starting point. Canz belongs to the first generation of ‘Wolffian theologians’, but retains a certain independence from the topoi of Wolffian philosophy and follows paths which are entirely his own. A detailed examination of these is one of the many desiderata for researchers engaging with the philosophy of the 18th century. (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.

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 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.

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)

Kaplan says that monsters violate Principle 2 of his theory. Principle 2 is that indexicals, pure and demonstrative alike, are directly referential. In providing this explanation of there being no monsters, Kaplan feels his theory has an advantage over double-indexing theories like Kamp’s or Segerberg’s (or Stalnaker’s), which either embrace monsters or avoid them only by ad hoc stipulation, in the sharp conceptual distinction it draws between circumstances of evaluation and contexts of utterance. We shall argue that Kaplan’s prohibition is (...) also essentially stipulative, and that it is too general. The main difference between ourselves and Kaplan is that the basic carriers of a truth-value is a sentence-in-a-context; our account is utterance-based. (shrink)

_Worlds of Truth: A Philosophy of Knowledge_ explicates and builds upon a half century of philosophical work by the noted philosopher Israel Scheffler. Propounds a new doctrine of _plurealism_ which maintains the existence of multiple real worlds Offers a defense of absolute truth, which denies certainty and eschews absolutism, and defends systematic relativity, objectivity, and fallibilism Emphasizes a wide range of pragmatic interests: epistemology and scientific development, cognition and emotion, science and ethics, ritual and culture, and art and science.
