This article presents a characterization of higher-order risk preferences such as prudence or temperance in terms of statistical moments. Our results, which are generalizations of Roger :27–44, 2011) and Ekern, 329–333, 1980), give a better understanding of how higher-order risk preferences relate to skewness preference and kurtosis aversion. While they are not based on expected utility theory, an implication within that theory is that all commonly used utility functions exhibit skewness preference and kurtosis aversion.

Roger North's The Musicall Grammarian 1728 is a treatise on musical eloquence in all its branches. Of its five parts, I and II, on the orthoepy, orthography and syntax of music, constitute a grammar; III and IV, on the arts of invention and communication, form a rhetoric; and V, on etymology, consists of a history. Two substantial chapters of commentary introduce the text, which is edited here for the first time in its entirety: Jamie Kassler places his treatise within the (...) broader context not only of North's musical and non-musical writings but also their relation to the intellectual ferment of the seventeenth and eighteenth centuries and Mary Chan describes physical and textual aspects of the treatise as evidence for North's processes of thinking about musical thinking.

[Sebastian Gardner] German idealism has been pictured as an unwarranted deviation from the central epistemological orientation of modern philosophy, and its close historical association with German romanticism is adduced in support of this verdict. This paper proposes an interpretation of German idealism which seeks to grant key importance to its connection with romanticism without thereby undermining its philosophical rationality. I suggest that the fundamental motivation of German idealism is axiological, and that its augment of Kant's idealism is intelligible in (...) terms of its combined aim of consolidating the transcendental turn and legitimating the kind of relation to value articulated in German romanticism. /// [Paul Franks] German idealists regard Spinozism as both the realism that outflanks Kant's idealism and the source of the conception of systematicity with which to fortify idealism. But they offer little argument for this view. To fill the gap, I reconstruct arguments that could underlie Jacobi's and Pistorius's tentative but influential suggestions that Kant is or should be a Spinozist. Kant is indeed a monist about phenomena, but, unlike Spinoza, a pluralist about noumena. Nevertheless, it is arguable that the Third Antinomy can be solved by a more thoroughgoing Spinozistic monism. The resulting Spinozism outflanks Kant by acknowledging Jacobi's charge that philosophy annihilates immediacy and individuality, whereas Kant's commitment to things in themselves can seem a half-hearted attempt to avoid the charge. However, the German idealist contention is that only a synthesis of such a Spinozism with Kantian idealism can retrieve immediacy and individuality, thus overcoming nihilism. (shrink)

This paper defends moral testimony pessimism, the view that there is something morally or epistemically regrettable about relying on the moral testimony of others, against several arguments in Lillehammer. One central such argument is that reliance on testimony is inconsistent with the exercise of true practical wisdom. Lillehammer doubts whether such reliance is always objectionable, but it is important to note that moral testimony pessimism is best understood as a view about the pro tanto, rather than the overall, badness of (...) relying on testimony. One must also be clear about what counts as genuine moral testimony: there will be morally charged occasions when a virtuous person will properly rely on the views of others. It can also plausibly be argued that relying on moral testimony may constitute a lack of full autonomy. After discussing some remaining issues concerning the definition of moral testimony, a possible analogy between lying and relying on testimony, and the implications of untrustworthiness for the truth of moral testimony pessimism, the paper ends with a return to the case against relying on moral testimony, grounded on a conception of the role of knowledge and understanding in virtue.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. The first volume covers the beginnings of a career that is ground-breaking from the outset. Inspired by courses given by Dirac and Bondi, much of the early published (...) work involves linking general relativity with tensor systems. Among his early works is the seminal 1955 paper, 'A Generalized Inverse for Matrices', his previously unpublished PhD and St John's College Fellowship theses, and from 1967, his Adam's Prize-winning essay on the structure of space-time. Add to this his 1965 paper, 'Gravitational collapse and space-time singularities', and the 1967 paper that introduced a remarkable new theory, 'Twistor algebra', and this becomes a truly stellar procession of works on mathematics and cosmology.

Professor Sir Roger Penrose is one of the truly original thinkers of our time. He has made several remarkable contributions to science, from quantum physics and theories of human consciousness to relativity theory and observations on the structure of the universe. Unusually for a scientist, some of his ideas have crossed over into the public arena. Now his work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the (...) first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. (shrink)

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Many important realizations concerning twistor theory occurred during the short period of this third volume, providing a new perspective on the way that mathematical features of the complex (...) geometry of twistor theory relate to actual physical fields. Following on from the nonlinear graviton construction, a twistor construction was found for (anti-)self-dual electromagnetism allowing the general (anti-)self-dual Yang-Mills field to be obtained. It became clear that some features of twistor contour integrals could be understood in terms of holomorphic sheaf cohomology. During this period, the Oxford research group founded the informal publication, Twistor Newsletter. This volume also contains the influential Weyl curvature hypothesis and new forms of Penrose tiles.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Among the new developments that occurred during this period was the introduction of a particular notion of 'quasi-local mass-momentum and angular momentum', the topic of Penrose's Royal Society (...) paper. Many encouraging results were initially obtained but, later, difficulties began to emerge and remain today. Also, an extensive paper (with Eastwood and Wells) gives a thorough account of the relation between twistor cohomology and massless fields. This volume witnesses Penrose's increasing conviction that the puzzling issue of quantum measurement could only be resolved by the appropriate unification of quantum mechanics with general relativity, where that union must involve an actual change in the rules of quantum mechanics as well as in space-time structure. Penrose's first incursions into a possible relation between consciousness and quantum state reduction are also covered here. (shrink)

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Publication of The Emperor's New Mind (OUP 1989) had caused considerable debate and Penrose's responses are included in this volume. Arising from this came the idea that large-scale (...) quantum coherence might exist within the conscious brain, and actual conscious experience would be associated with a reduction of the quantum state. Within this collection, Penrose also proposes that a twistor might usefully be regarded as a source (or 'charge') for a massless field of spin 3/2, suggesting that the twistor space for a Ricci-flat space-time might actually be the space of such possible sources. Towards the end of the volume, Penrose begins to develop a quite different approach to incorporating full general relativity into twistor theory. This period also sees the origin of the Diósi-Penrose proposal. (shrink)

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. This sixth volume describes an actual experiment to measure the length of time that a quantum superposition might last (developing the Diósi-Penrose proposal). It also discusses the significant (...) progress made in relation to incorporating the 'googly' information for a gravitational field into the structure of a curved twistor space. Penrose also covers such things as the geometry of light rays in relation to twistor-space structures, the utility of complex numbers in drawing three-dimensional shapes, and the geometrical representation of different types of musical scales. The turn of the millennium was also an opportunity to reflect on progress in many areas up until that point. (shrink)

Where relevant, individual papers also come with specific introductions or notes. Developing ideas sketched in the first volume, twistor theory is now applied to genuine issues of physics, and there are the beginnings of twistor diagram theory (an analogue (...) of Feynman Diagrams). This collection includes joint papers with Stephen Hawking, and uncovers certain properties of black holes. The idea of cosmic censorship is also first proposed. Along completely different lines, the first methods of aperiodic tiling for the Euclidean plane that come to be known as Penrose tiles are described. This volume also contains Penrose's three prize-winning essays for the Gravity Foundation (two second places with both Ezra Newman and Steven Hawking, and a solo first place for 'The Non-linear graviton').

A generation of students at the Faculty of Theology of the K.U.Leuven have been introduced by Roger Burggraeve to the thoughts of Emmanuel Levinas. Levinas has been for him a true "master in thinking". For Levinas responsibility is heteronymous because it does not start from the "I" but from the epiphany of the other as the face, appealing to me not "to kill" but to promote him/her. In and through the appeal of the face, the difference between the other and (...) me - expressed in the irreducible alterity of the other - is, ethically speaking, the appeal to the highest "non-indifference": proximity without absorption. As Levinas' thinking carries on obvious Jewish-Talmudic imprint, Burggraeve was interested as to how the concept of responsibility can be connected to a biblically inspired ethic. In which way can the Levinasian view on responsibility enhance a Christian anthropology, and in particular that one articulated by Louvain personalism, and in its turn inspired by a Christian anthropology, so that it benefits from uniquely Christian accents? In this Festschrift for Roger Burggraeve, authors explore the theme of "Responsibility, God and Society" in order to answer two questions. What does Levinas' ethic of responsibility have to offer Christian theology? And vice-versa, what can Christian theology offer to contemporary ethical thought on personal, relational and societal responsibility. (shrink)

Human beings talk and co-operate, they build and produce, they work to accumulate and exchange, they form societies, laws and institutions, and, in all these things the phenomenon of reason—as a distinct principle of activity—seems dominant. There are indeed theories of the human which describe this or that activity as central—speech, say, productive labour, or political existence. But we feel that the persuasiveness of such theories depends upon whether the activity in question is an expression of the deeper essence, reason (...) itself, which all human behaviour displays.

Speaking is so closely associated with making noises that such descriptions as ‘silent soliloquy’ and ‘soundless monologue’ have an air of paradox. Yet people frequently say things to themselves in such a way that not even a close observer has any reason to think they have done so. It is therefore tempting to suppose that on such occasions a sequence of surrogate speech sounds is produced in the person's head which he alone hears or introaudits, as if what distinguishes silent (...) inner speech from normal speech is that the word substitutes are conveniently hidden from all save their producer.

He who has seen everything empty itself is close to knowing what everything is filled with. Emptiness is probably the most important philosophical and religious concept of Mahayana Buddhism. Its precise meaning has been explained differently by different schools and in different Buddhist cultures, but almost all Mahāyāna Buddhists would agree with the following characterization: Philosophically , emptiness is the term that describes the ultimate mode of existence of all phenomena, namely, as naturally ‘empty’ of enduring substance, or self-existence : (...) rather than being independently self-originated, phenomena are dependently originated from causes and conditions. Emptiness, thus, explains how it is that phenomena change and interact as they do, how it is that the world goes on as it does. Religiously , emptiness is the single principle whose direct comprehension is the basis of liberation from samsāra, and ignorance of which, embodied in self-gasping is the basis of continued rebirth – hence suffering – in samsāra.

A corrected and extensively annotated version of the sole meeting between two of the most important figures in twentieth-century intellectual life.

What is the relation of the biological to the social sciences? Fierce battles are being currently fought over this question and much hangs on the answer. If society is taken as an irreducible category which can only be understood in its own terms, the social sciences can feel safe from the sinister designs of other disciplines. Yet it is a commonplace that cultures vary, and we humans are prone to look at the differences rather than the similarities between them. The (...) result can be a thoroughgoing relativism. If culture cannot be understood by means of any non-cultural categories, cultural differences themselves can be accepted as the ultimate truth about man. When everything is cultural, even the notion of a non-cultural category can seem to be a ludicrous contradiction in terms. The categories with which we think are the product of our culture, or so we are told. Instead of our being able to understand culture in terms of anything beyond itself, our understanding appears totally moulded by the society to which we belong. Any theory can thus be seen as merely the expression of the beliefs of a particular society. (shrink)

On Becoming an Effective Teacher presents the final unpublished writings of Rogers and as such has a unique historical value. It also documents the research results of four highly relevant, related but independent studies which comprise the biggest collection of data ever accumulated to test a person-centred theory in the field of education. This body of comprehensive research on effective teaching was accomplished over a twenty-year period in 42 States in the U.S. and in six other countries including the (...) UK, Germany, Brazil, Canada, Israel, and Mexico, and is highly relevant to the concerns of teachers, psychologists, students, and parents. The principal findings of the research in this book show that teachers and schools can significantly improve their effectiveness through programs focusing on facilitative interpersonal relationships. Teachers who either naturally have, or are trained to have empathy, genuineness (congruence), and who prize their students (positive regard) create an important level of trust in the classroom and exert significant positive effects on student outcomes including achievement scores, interpersonal functioning, self-concept, and attendance. The dialogues between Rogers and Lyon offer a unique and timeless perspective on teaching, counselling and learning. The work of Reinhard Tausch on person-centered teaching to counselors, parents, athletics, and even textbook materials, as well as research on the interactions of teachers and students, is among the most thorough and rigorous research ever accomplished on the significance and potential of a person-centered approach to teaching and learning.

What is attention? How does attention shape consciousness? In an approach that engages with foundational topics in the philosophy of mind, the theory of action, psychology, and the neurosciences this book provides a unified and comprehensive answer to both questions. Sebastian Watzl shows that attention is a central structural feature of the mind. The first half of the book provides an account of the nature of attention. Attention is prioritizing, it consists in regulating priority structures. Attention is not another (...) element of the mind, but constituted by structures that organize, integrate, and coordinate the parts of our mind. Attention thus integrates the perceptual and intellectual, the cognitive and motivational, and the epistemic and practical. The second half of the book concerns the relationship between attention and consciousness. Watzl argues that attentional structure shapes consciousness into what is central and what is peripheral. The center-periphery structure of consciousness cannot be reduced to the structure of how the world appears to the subject. What it is like for us thus goes beyond the way the world appears to us. On this basis, a new view of consciousness is offered. In each conscious experience we actively take a stance on the world we appear to encounter. It is in this sense that our conscious experience is our subjective perspective. (shrink)

Legal theory for the purposes of this essay is the theory of mundane law—that is, our law. The legal system of a modern Western democracy is the phenomenon legal theory is trying to represent perspicuously. Such a legal system may be characterized prephilosophically as an institutionalized normative system. The associated institutions include legislatures, courts, police forces, civil services, royal families, and the like. The associated norms are of three kinds—norms directly enjoining, permitting or proscribing behaviour on the part of the (...) norm-subjectss; norms for facilitating the creation of social arrangements between norm-subjects; norms for the creation, variation, administration, application and enforcement of norms of the first two kinds.

In 1981 Eleonore Stump and Norman Kretzmann published a landmark article aimed at exploring the classical concept of divine eternity. 1 Taking Boethius as the primary spokesman for the traditional view, they analyse God's eternity as timeless yet as possessing duration. More recently Brian Leftow has seconded Stump and Kretzmann's interpretation of the medieval position and attempted to defend the notion of a durational eternity as a useful way of expressing the sort of life God leads. 2 However, there are (...) good reasons to reject the idea that divine timelessness should be thought of as having duration. The medievals probably did not accept it, as it contradicts a principle of classical metaphysics even more fundamental than the atemporality of the divine. In any case, it is not possible to express the notion of durational eternity in even a minimally coherent way, and the attempt to salvage the concept by appealing to the Thomistic doctrine of analogy is unsuccessful. The best analogy for God's eternity is still the one proposed by Augustine at the end of the fourth century. God lives in a timeless ‘present’, unextended like our temporal present, but immutable and encompassing all time. (shrink)

This paper argues for the normative significance of attention. Attention plays an important role when describing an individual’s mind and agency, and in explaining many central facts about that individual. In addition, many in the public want answers and guidance with regard to normative questions about attention. Given that attention is both descriptively central and the public cares about normative guidance with regard to it, attention should be central also in normative philosophy. We need an ethics of attention: a field (...) of study of which normative pressures, if any, govern attention. Like the ethics of belief, the ethics of attention will connect those normative questions to issues regarding the nature of attention, i.e. to what is subject to such normative pressures. Philosophers should develop an ethics of attention that helps to provide normative guidance and that is commensurate in its richness to the descriptive significance of attention. The second half of the paper sketches a framework that may help us to get started at developing the ethics of attention. (shrink)

The obligation of a court to follow the law of a superior court is commonly taken to be stronger than the obligation of the higher court to respect its own precedent. The Supreme Court has recently asserted this stronger obligation in the most forceful terms. What follows is an attempt to demonstrate that this is wrong as a matter of policy and as a matter of law.

The publication of Frege’s Begriffsschrift in 1879 forever altered the landscape for many Western philosophers. Here, Sebastian Rödl traces how the Fregean influence, written all over the development and present state of analytic philosophy, led into an unholy alliance of an empiricist conception of sensibility with an inferentialist conception of thought. -/- According to Rödl, Wittgenstein responded to the implosion of Frege’s principle that the nature of thought consists in its inferential order, but his Philosophical Investigations shied away from (...) offering an alternative. Rödl takes up the challenge by turning to Kant and Aristotle as ancestors of this tradition, and in doing so identifies its unacknowledged question: the relation of judgment and truth to time. Rödl finds in the thought of these two men the answer he urges us to consider: the temporal and the sensible, and the atemporal and the intelligible, are aspects of one reality and cannot be understood independently of one another. In demonstrating that an investigation into the categories of the temporal can be undertaken as a contribution to logic, Rödl seeks to transform simultaneously our philosophical understanding of both logic and time.

Im Alltag äußern wir nicht nur Aussagen darüber, wie die Welt tatsächlich beschaffen ist, sondern auch darüber, was notwendigerweise oder möglicherweise der Fall ist. Doch worin ist die Wahrheit solcher sogenannten Modalaussagen fundiert? Auf diese Frage gibt Gottfried Wilhelm Leibniz bereits in der Frühen Neuzeit eine höchst interessante Antwort: Für ihn sind modale Wahrheiten im Intellekt Gottes fundiert. Diese Modalitätskonzeption analysiert Sebastian Bender in der vorliegenden Studie auf systematisch informierte Weise. Dabei kommt er zu folgenden Ergebnissen: Erstens vertritt Leibniz, (...) anders als häufig angenommen, eine nicht-reduktionistische Metaphysik der Modalität– Modales wird von ihm also nicht auf etwas Nicht-Modales reduziert. Zweitens ist Leibniz' Theorie der Modalität kombinatorisch geprägt. Drittens repräsentieren mögliche Welten für Leibniz nicht alles metaphysisch Mögliche. Gott kann im Prinzip auch Ansammlungen von Substanzen erschaffen, die keine Welten konstituieren. Viertens schließlich ist das für Leibniz zentrale Prinzip des zureichenden Grundes kontingent und nicht, wie häufig vorausgesetzt, notwendig. Auf diese Weise gelingt es Leibniz, seinen Rationalismus mit seinem Theismus zu verbinden. (shrink)
