This volume is intended for use in an undergraduate philosophy course employing the problems' approach. Chapter I provides a clear presentation of Cartesian rationalism. Following the exposition of Descartes' position, there is a section on the standard criticisms levelled by B. Russell. Aune defends the rationalist position with an outline of the traditional arguments for the validity of intuitive knowledge. Chapter I terminates with a list of "Study Questions" and an annotated bibliography suggesting further readings. Chapter II considers classical English (...) empiricism, taking the thought of Hume as paradigmatic. There is a discussion of a priori and a posteriori knowledge as well as a section on the problems of induction and solipsism. Chapter III outlines the attempts of contemporary empiricists to eschew Hume's skepticism by envisioning the world as a construct of our sensory experiences. To avoid the solipsism still implicit in the latter position, a re-evaluation of Hume's theory of perception is offered. Wittgenstein and Strawson are briefly treated in this section. Chapter IV explains the pragmatist's attempt to reduce to the same untenable position the rationalist and empiricist views of the a priori. Chapter V concentrates on the pragmatic theory of justification and includes a treatment of N. Goodman's "new riddle of induction." Aune's book is a readable account of conflicting theories of knowledge and undergraduates should find it of value.--W. J. L. (shrink)

The bulk of this book is the second series of John Dewey Lectures, delivered by Professor Ayer in April 1970. To this, Ayer has added a criticism of Roy Harred’s purported refutation of Hume and a chapter about "non-truth-functional" conditionals that rounds out the lectures. Leaving Harred aside, this book provides an elegant, concise, and up-to-date introduction to the problem of induction and related issues concerning probability. Hume is here vindicated. Beginning by giving what may be the best, updated paraphrase (...) of Hume’s negative argument about causal judgments, Ayer explicates the subsumed atomicity, the denial of natural necessity, and the claimed vacuity or circularity of introducing the "uniformity of nature." Ayer goes on to distinguish a priori or logical probabilities, statistical or frequency judgments, and credibility or ground floor inductive judgments, and he summarily argues that the admissibility of the first two forms of judgment, properly understood, provides no real justification for credibility judgments, which, though not defined as subjective, turn out to need some support from our decision to project and therefore entrench certain predicates, or take as lawlike certain generalizations, rather than others. Ayer here includes a very clear explication and criticism of Carnap’s way out in the Logical Concept of Probability, and elsewhere. Ayer acutely summarizes and discusses the Hempel and Goodman paradoxes, taking a position substantially in agreement with Quine and Goodman, and welds this discussion into a Humean conclusion: "In a certain sense cases are what we choose them to be. We do not decide what facts habitually go together but we do decide what combinations are to be imaginatively projected. The despised savages who beat gongs at solar eclipses to summon back the sun are not making any factual error. It is a true generalization that whenever they beat the gongs the sun does shine again, and if they always keep up the ceremony, it is also a true generalization that the sun comes out again only when they beat the gongs. If we despise them, it is because they tell a fictional story about what would happen if they did not beat the gongs, which we do not accept. They see what goes on as well as we do; it is just that we have a different and, we think, a better idea of the way the world works." To say all this is just, of course, to summarize and refurbish Hume’s position on causality. But to do that has two very real values now: 1) It underlines and exposes the epistemic basis of the position taken by Hume’s heirs; 2) It makes clear what are the departures required if one is to differ in substance from Hume and Ayer.—J.

This is unarguably the best short introduction to the whole of Bertrand Russell’s philosophical work. I am sure it is the best introduction of any length to Russell, and I suspect that it might serve as one of the best introductions to modern philosophy. Its greatest virtues are conciseness, comprehensiveness, and lucidity: virtues generally associated with Professor Ayer, but here found in unhoped for abundance. Ayer begins with a brief, austere, and balanced account of Russell’s life: as in Russell’s autobiography (...) this means his thought, books, women, and politics. Tacitus would have found the account exemplary. Ayer ends with a sympathetic and surprisingly detailed survey of Russell’s social philosophy. But the bulk of this book consists of a chapter on Russell’s work in logic and the foundations of mathematics, followed by a chapter on his epistemological views and one on metaphysics: descending in that order, also, in length and emphasis. The chapter on philosophical logic manages a clear and comprehensive elucidation of Russell’s "supreme maxim": "Whenever possible, logical constructions are to be substituted for inferred entities." Both the theory of types and of definite descriptions fall into place within this general project; and the reader is given a crisp, though unavoidably rudimentary, account of how the axioms of infinity and reducibility came to seem indispensable if the logical reduction of numbers and classes were to succeed. The chapter on Russell’s theory of knowledge is also admirably comprehensive and concise. One finds here a very striking, sympathetic but critical, account of the attempt to take tables and chairs, etc., as logical constructions out of sense data. Both Quine and Goodman come into the discussion : This attempt to understand and criticize Russell in terms of contemporary philosophical arguments seems to contribute both vitality and clarity to the discussion. I find it impossible to imagine that this book will not remain indefinitely the very best book of its sort.—J. L. (shrink)

Drawing upon two independent national samples of 201 and 241 psychology graduate students, this article describes the development and psychometric evaluation of 4 Web-based student self-report scales tapping student socialization in the responsible conduct of research (RCR) with human participants. The Mentoring the Responsible Conduct of Research Scale (MRCR) is composed of 2 subscales assessing RCR instruction and modeling by research mentors. The 2 subscales of the RCR Department Climate Scale (RCR-DC) assess RCR department policies and faculty and student RCR (...) practices. The RCR Preparedness scale (RCR-P) and the RCR Field Integrity scale (RCR-FI) measure respectively students' confidence in their ability to conduct research responsibly and their belief in the RCR integrity of psychology as a discipline. Factor analysis, coefficient alphas, correlations, and multiple regression analyses demonstrated each of the scales had good internal consistency and concurrent and construct validity. (shrink)

Ample research links mothers’ postpartum depression (PPD) to adverse interactions with their infants. However, most studies relied on general population samples, whereas a substantial number of women are at elevated depression risk. The purpose of this study was to describe mothers’ interactions with their 6- and 12-month-old infants among women at elevated risk, although with a range of symptom severity. We also identified higher-order factors that best characterized the interactions and tested longitudinal consistency of these factors from 6 to 12 (...) months of infant age. We leveraged data from eight projects across the United States (n = 647), using standardized depression measures and an adaptation of the NICHD Mother-Infant Interaction Scales. Overall, these depression-vulnerable mothers showed high levels of sensitivity and positive regard and low levels of intrusiveness, detachment, and negative regard with their infants. Factor analyses of maternal behaviors identified two overarching factors—“positive engagement” and “negative intrusiveness” that were comparable at 6 and 12 months of infant age. Mothers’ ability to regulate depressed mood was a key behavior that defined “positive engagement” in factor loadings. An exceptionally strong loading of intrusiveness on the second factor suggested its central importance for women at elevated depression risk. Mothers with severe depressive symptoms had significantly more “negative intrusiveness” and less “positive engagement” with their 6-month-old infants than women with moderate or fewer depressive symptoms, suggesting a potential tipping point at which symptoms may interfere with the quality of care. Results provide the foundation for further research into predictors and moderators of women’s interactions with their infant among women at elevated risk for PPD. They also indicate a need for evidence-based interventions that can support more severely depressed women in providing optimal care. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

If Bayesian Fundamentalism existed, Jones & Love's (J&L's) arguments would provide a necessary corrective. But it does not. Bayesian cognitive science is deeply concerned with characterizing algorithms and representations, and, ultimately, implementations in neural circuits; it pays close attention to environmental structure and the constraints of behavioral data, when available; and it rigorously compares multiple models, both within and across papers. J&L's recommendation of Bayesian Enlightenment corresponds to past, present, and, we hope, future practice in Bayesian cognitive science.

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

La ressemblance, je dirais, est sournoise. Et s’il est perfide d’associer la ressemblance à la perfidie, c’est encore mieux. Toujours prête à résoudre des problèmes philosophiques et à proposer ses services, la ressemblance est une hypocrite, une imposture, une arnaque. Si elle a, certes, ses lieux et ses usages, on la trouve plus souvent là où elle ne devrait pas être, s’attribuant des pouvoirs qu’elle ne possède pas.

J.L. Ackrill's work on Plato and Aristotle has had a considerable influence upon ancient philosophical studies in the late twentieth century. This volume collects the best of Ackrill's essays on the two greatest philosophers of antiquity. With philosophical acuity and philological expertise he examines a wide range of texts and topics--from ethics and logic to epistemology and metaphysics--that continue to be in the focus of debate.

The traditional verbal/nonverbal dichotomy is inadequate for completely describing cerebral lateralization. Musical functions are not necessarily mediated by the right hemisphere; evidence for a specialist left-hemisphere mechanism dedicated to the encoded speech signal is weakening, and the right hemisphere possesses considerable comprehensional powers. Right-hemisphere processing is often said to be characterized by holistic or gestalt apprehension, and face recognition may be mediated by this hemisphere partly because of these powers, partly because of the right hemisphere's involvement in emotional affect, and (...) possibly through the hypothesized existence of a specialist face processor or processors in the right. The latter hypothesis may, however, suffer the same fate as the one relating to a specialist encodedness processor for speech in the left. Verbal processing is largely the province of the left because of this hemisphere's possession of sequential, analytic, time-dependent mechanisms. Other distinctions are special cases of an analytic/holistic dichotomy. More fundamentally, however, the left hemisphere is characterized by its mediation of discriminations involving duration, temporal order, sequencing, and rhythm, at thesensory level, and especially at themotorlevel. Spatial aspects characterize the right, the mapping of exteroceptive body space, and the positions of fingers, limbs, and perhaps articulators, with respect to actual and target positions. Thus there is a continuum of function between the hemispheres, rather than a rigid dichotomy, the differences being quantitative rather than qualitative, of degree rather than of kind. (shrink)

_The Foundations of Arithmetic_ is undoubtedly the best introduction to Frege's thought; it is here that Frege expounds the central notions of his philosophy, subjecting the views of his predecessors and contemporaries to devastating analysis. The book represents the first philosophically sound discussion of the concept of number in Western civilization. It profoundly influenced developments in the philosophy of mathematics and in general ontology.

Aristotle is widely regarded as the greatest of all philosophers; indeed, he is traditionally referred to simply as `the philosopher'. Today, after more than two millennia, his arguments and ideas continue to stimulate philosophers and provoke them to controversy. In this book J.L. Ackrill conveys the force and excitement of Aristotle's philosophical investigations, thereby showing why contemporary philosophers still draw from him and return to him. He quotes extensively from Aristotle's works in his own notably clear English translation, and a (...) picture emerges of a lucid, lively, subtle and tough-minded thinker of astonishing range and penetration. Professor Ackrill identifies many striking connections between Aristotle's ideas and ideas in recent philosophy; he also raises philosophical questions of his own, and exemplifies the way in which Aristotle can still be argued with and learned from.

In a single volume intended for philosophy students of all levels as well as their teachers, this reader provides modern, accurate translations of the texts necessary for a careful study of most aspects of Aristotle's philosophy. Professor Ackrill has drawn on his broad experience of teaching graduate classes in selecting the texts, and his choice reflects issues of current philosophical interest as well as the perennial themes. Only recent translations which achieve a high level of accuracy have been chosen: the (...) aim is to place the reader without Greek, as nearly as possible, in the position of a reader of Greek. As an aid to study, a valuable guide to the key topics covered is also suppied, giving references to works or passages contained in the reader, an indication of their interrelation, and a currnet bibliography.
