Recent studies have provided evidence of associations between neurochemistry and reading (dis)ability (Pugh et al., 2014). Based on a long history of studies indicating that fluent reading entails the automatic convergence of the written and spoken forms of language and our recently proposed Neural Noise Hypothesis (Hancock et al., 2017), we hypothesized that individual differences in cross-modal integration would mediate, at least partially, the relationship between neurochemical concentrations and reading. Cross-modal integration was measured in 231 children using a two-alternative forced (...) choice cross-modal matching task with three language conditions (letters, words, and pseudowords) and two levels of difficulty within each language condition. Neurometabolite concentrations of Choline (Cho), Glutamate (Glu), gamma-Aminobutyric (GABA), and N- acetyl-aspartate (NAA) were then measured in a subset of this sample (n = 70) with Magnetic Resonance Spectroscopy (MRS). A structural equation mediation model revealed that the effect of cross-modal word matching mediated the relationship between increased Glu (which has been proposed to be an index of neural noise) and poorer reading ability. In addition, the effect of cross-modal word matching fully mediated a relationship between increased Cho and poorer reading ability. Multilevel mixed effects models confirmed that lower Cho predicted faster cross-modal matching reaction time, specifically in the hard word condition. These Cho... (shrink)

Physics in Oxford, 1839-1939 offers a challenging new interpretation of pre-war physics at the University of Oxford, which was far more dynamic than most historians and physicists have been prepared to believe. It explains, on the one hand, how attempts to develop the University's Clarendon Laboratory by Robert Clifton, Professor of Experimental Philosophy from 1865 to 1915, were thwarted by academic politics and funding problems, and latterly by Clifton's idiosyncratic concern with precision instrumentation. Conversely, by examining in detail the work (...) of college fellows and their laboratories, the book reconstructs the decentralized environment that allowed physics to enter on a period of conspicuous vigour in the late nineteenth and early twentieth centuries, especially at the characteristically Oxonian intersections between physics, physical chemistry, mechanics, and mathematics. Whereas histories of Cambridge physics have tended to focus on the self-sustaining culture of the Cavendish Laboratory, it was Oxford's college-trained physicists who enabled the discipline to flourish in due course in university as well as college facilities, notably under the newly appointed professors, J. S. E. Townsend from 1900 and F. A. Lindemann from 1919. This broader perspective allows us to understand better the vitality with which physicists in Oxford responded to the demands of wartime research on radar and techniques relevant to atomic weapons and laid the foundations for the dramatic post-war expansion in teaching and research that has endowed Oxford with one of the largest and most dynamic schools of physics in the world.

One of the most serious pre-occupations of post-medieval philosophy has been to distinguish those kinds of assertion which are either true or false from those which are neither true nor false. A solution to this problem would be of the highest importance. It would indicate in what areas rational inquiry has some hope of success and in what areas it is doomed to frustration. It would tell us, for example, whether it is worth trying to think about the possible mistakenness (...) of our moral principles, or whether such thinking is bound to be ineffective since no truth or falsity attaches to them.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Professor Lewis and I have some important differences of opinion regarding the identity and distinctness of conscious persons, which it will be well to try to clarify on the present occasion, first of all by enumerating a number of points on which we are, I think, in agreement. Both of us believe in the existence of individual persons, each of whom can be said to live in a ‘world’ of his own intentional objectivity, a world ‘as it is for him’, (...) which differs in a considerable extent, both in content and emphasis, from the world as it is for anyone else. Both of us further believe that all these intentionally objective worlds for a large part coincide in content, and are in fact excerpted from a more comprehensive real world which is common to us all, and which, in addition to in some sense including all such intentionally objective worlds, also includes many real material objects which exist regardless of our intentionality, and which further includes our own material bodies, which appear in so central a manner in each of our intentionally objective worlds. Both of us believe in matter as a transcendent reality, as well as an intentional object, and are content to accept the dicta of science as to the most probable view of its structure. We are in fact quite Cartesian and Lockean in our belief in the primary and secondary qualities of matter. We believe further that our intentional subjectivity is geared causally into our material objectivity, and that the gearing takes place, in some inscrutable manner, in our nervous systems. We both also believe that our intentional subjectivity transcends bodily mechanisms and instrumentalities, and can be liberated from the latter, but that, when thus liberated, our subjectivity may still affect some sort of an intentionally objective material body such as we wear in dreams, a body in which it will manifest itself to itself and to others much as we do in our dreams and fantasies.

The aim of this paper is to give a characterisation of religion and the Religious Spirit, basing itself on the Platonic assumption that there are Forms, salient jewels of simplicity and affinity, to be dug out from the soil of vague experience and cut clear from the confusedly shifting patterns of usage, which will give us conceptual mastery over the changeable detail in a given sector. It will further be Platonic in that it will not seek to discount the deep (...) gulfs between the species into which religion qua genus divides itself, i.e. its theistic, polytheistic and atheistic subvarieties, taking it to be of the essence of a true genus to extend itself over mutually exclusive species, only being what it is by including in its sense the alternatives which are thus mutually exclusive. And my treatment will be Platonic, thirdly, in that it will endeavour to delimit the Religious Spirit by, on the one hand, setting it over against what it excludes, all purely this-world talk and life which is quite irreligious, and by, on the other hand, opposing it to forms of talk and life which fall short of it in various ways or which deviate from it variously, thereby likewise contributing to our understanding of what it is. The practice of Plato, which could study the deviations from his ideal city in order to confirm his notion of its structure and excellence, and which also paired every ideal pattern with its opposite— piety with impiety, justice with self-interested tyranny, etc.—is plainly one to be followed: Plato, as we know from a citation from his contemporary Hermodorus in one of the Aristotelian commentators, always set beside the ‘in itself’ of the pure Form the deviant and the wholly negative which were nonetheless part of its sense. Religion will therefore stand before us as a target that it is possible to fall short of or miss altogether as well as to hit squarely, and we shall try by a series of glancing darts to end by hitting it squarely.

The background and purpose of this paper require some explanation. It is not the product of a New Testament scholar, able to weigh and balance theories as to date, origin and doctrinal background of the text attributed to St John, nor to assess the identification of its author with the beloved Disciple elsewhere mentioned or with the author of the Apocalypse, nor to consider his relationship to Gnostics or Stoics or Essenes or other influences in the contemporary Jewish or Christian (...) ambience. It is only the effort of one who recognizes in St John's Gospel, if read with an appropriate hermeneutic, a supreme mystico-religious document which can provide guidance at every turn of the spiritual life, but which, if read in another manner, becomes only the expression of a hard-line particularism, which is not less unacceptable in that it acclaims a particular standing in a special relation to another particular on which we all depend for our existence and for all our properties. Conceive of God, or the supreme object of worship, as a particular among particulars, and as much other than ourselves as other things and persons are other, and religious reverence becomes a repugnant form of heteronomous idolatry, wrought up, moreover, with the blind acceptance of a large number of historic and cosmic myths. But conceive of God as being something beyond category-differences, and which as much transcends particularity as it transcends any form of abstract universality, and which incorporates in strict identity all those values of Truth, Love, Beauty, Justice, etc. which are all simply universality in action, and which, moreover, as much transcends personality and personal relationships as it also may have in them its supreme expression, and religion and worship at once acquire a perfect sense and reference.

The theory of mental models and its computer implementations have led to crucial experiments showing that no standard logic—the sentential calculus and all logics that include it—can underlie human reasoning. The theory replaces the logical concept of validity (the conclusion is true in all cases in which the premises are true) with necessity (conclusions describe no more than possibilities to which the premises refer). Many inferences are both necessary and valid. But experiments show that individuals make necessary inferences that are (...) invalid, e.g., Few people ate steak or sole; therefore, few people ate steak. Other crucial experiments show that individuals reject inferences that are not necessary but valid, e.g., He had the anesthetic or felt pain, but not both; therefore, he had the anesthetic or felt pain, or both. Nothing in logic can justify the rejection of a valid inference: a denial of its conclusion is inconsistent with its premises, and inconsistencies yield valid inferences of any conclusions whatsoever including the one denied. So inconsistencies are catastrophic in logic. In contrast, the model theory treats all inferences as defeasible (nonmonotonic), and inconsistencies have the null model, which yields only the null model in conjunction with any other premises. So inconsistences are local. Which allows truth values in natural languages to be much richer than those that occur in the semantics of standard logics; and individuals verify assertions on the basis of both facts and possibilities that did not occur.

It has been hypothesized that psychedelic experiences elicit lasting psychological benefits by altering narrative selfhood, which has yet to be explicitly studied. The present study investigates retrospective reports (n = 418) of changes to narrative self that participants believe resulted from, or were catalysed by, their psychedelic experience(s). Responses to open-ended questions were analysed using inductive and deductive thematic coding and interpreted within agent-centred approaches to development and well-being. Themes include decentred introspection, greater access to self-knowledge, positive shifts in self-evaluation (...) processes, greater psychological and behavioural autonomy, and enhanced connectedness with others and the world. While this explorative qualitative study offers some initial support for the explanation that changes to narrative self are a cornerstone of psychedelics' therapeutic and transformative potential, methodological and recruiting limitations preclude the ability to make objective claims and generalizations. Future scientific research is necessary to further elucidate this hypothesized mechanism. (shrink)

How do we refer to people in everyday conversation? No matter the language or culture, we must choose from a range of options: full name ('Robert Smith'), reduced name ('Bob'), description ('tall guy'), kin term ('my son') etc. Our choices reflect how we know that person in context, and allow us to take a particular perspective on them. This book brings together a team of leading linguists, sociologists and anthropologists to show that there is more to person reference than meets (...) the eye. Drawing on video-recorded, everyday interactions in nine languages, it examines the fascinating ways in which we exploit person reference for social and cultural purposes, and reveals the underlying principles of person reference across cultures from the Americas to Asia to the South Pacific. Combining rich ethnographic detail with cross-linguistic generalizations, it will be welcomed by researchers and graduate students interested in the relationship between language and culture.

Professor Findlay in this book, originally published in 1961, set out to justify, and to some extent carry out, a ‘material value-ethic’, ie. A systematic setting forth of the ends of rational action. The book is in the tradition of Moore, Rashfall, Ross, Scheler and Hartmann though it avoids altogether dogmatic intuitive methods. It argues that an organised framework of ends of action follows from the attitude underlying our moral pronouncements, and that this framework, while allowing personal elaboration, is not (...) a matter for individual decision. The relations connecting our fundamental value-judgements with one another, and the frames of mind behind them, are not rigorously deductive but are sufficiently compelling to be called logical. Something of a ‘transcendental deduction’ of a well-ordered family for our basic heads of valuation is both possible and necessary. The work is further critical of the notion of obligation which has been extended far beyond legal contracts and understandings. The book also contains a chapter on religion. (shrink)

This volume is a collection of my essays on philosophy of logic from a phenomenological perspective. They deal with the four kinds of logic I have been concerned with: formal logic, transcendental logic, speculative logic and hermeneutic logic. Of these, only one, the essay on Hegel, touches upon 'speculative logic', and two, those on Heidegger and Konig, are concerned with hermeneutic logic. The rest have to do with Husser! and Kant. I have not tried to show that the four logics (...) are compatible. I believe, they are--once they are given a phenomenological underpinning. The original plan of writing an Introduction in which the issues would have to be formulated, developed and brought together, was abandoned in favor of writing an Introductory Essay on the 'origin'- in the phenomenological sense -of logic. J.N.M. Philadelphia INTRODUCTION: THE ORIGIN OF LOGIC The question of the origin of logic may pertain to historical origin (When did it all begin? Who founded the science of logic?), psychological origin (When, in the course of its mental development, does the child learn logical operations?), cultural origin (What cultural - theological, metaphysical and linguisti- conditions make such a discipline as logic possible?), or transcendental constitutive origin (What sorts of acts and/or practices make logic possible?).

International array of contributors, bringing together both traditional and more recent approaches to provide valuable insights into the poets’ use of language.Covers authors from Lucilius to Juvenal.Of the peoples of ancient Italy, only the Romans committed newly composed poems to writing, and for 250 years Latin-speakers developed an impressive verse literature.The language had traditional resources of high style, e.g., alliteration, lexical and morphological archaism or grecism, and of course metaphor and word order; and there were also less obvious resources in (...) the technical vocabularies of law, philosophy and medicine.The essays in this volume show how the poets in the classical period combined these elements, and so created a poetic medium that could comprehend satire, invective, erotic elegy, drama, lyric, and the grandest heroic epos.

All recent memory theories of hippocampal function have incorporated the idea that the hippocampus is required to process items only of some qualitatively specifiahle kind, and is not required to process items of some complementary set. In contrast, it is now proposed that the hippocampus is needed to process stimuli of all kinds, but only when there is a need to associate those stimuli with other events that are temporally discontiguous. In order to form or use temporally discontiguous associations, it (...) is essential to maintain some memory of the first component until the second component has occurred. When the temporal gap to he spanned is small, and the number of items to be temporarily retained is low, a limited-capacity, short-term store is sufficient to allow associations to be formed. Such a store is presumed to operate in parallel with the hippocampus in normal animals. Hippocampal damage disrupts a much higher-capacity store that has a slower decay rate, and so leaves animals with only a very limited ability to form temporally discontiguous associations. Hippocampal damage, however, is not held to affect the long-term storage of associations of any kind, if they can be formed. Analyses of both new and existing data are presented to show that by classifying tasks in terms of the need to use a temporary memory store to retain temporally discontiguous information one can cut right across existing classifications as well as achieve a better fit to the data. The hippocampus thus seems best described as a high-capacity, intermediate-term memory store. (shrink)

In his award-winning book _The Philosophy of Edmund Husserl: A Historical Development_, J. N. Mohanty charted Husserl's philosophical development from the young man's earliest studies—informed by his work as a mathematician—to the publication of his _Ideas_ in 1913. In this welcome new volume, the author takes up the final decades of Husserl's life, addressing the work of his Freiburg period, from 1916 until his death in 1938. As in his earlier work, Mohanty here offers close readings of Husserl's main texts (...) accompanied by accurate summaries, informative commentaries, and original analyses. This book, along with its companion volume, completes the most up-to-date, well-informed, and comprehensive account ever written on Husserl's phenomenological philosophy and its development. (shrink)
