L'Europe prétend être une personnalité culturelle née voilà des siècles dans l'Athènes des philosophes. Cette certitude est-elle lieu commun ou réalité vérifiée? Raymond Klibansky et David Pears ont dirigé, à la demande de l'Unesco, cette vaste enquête visant à dresser un état des lieux de la philosophie en Europe aujourd'hui. On y trouvera donc des inventaires, pays par pays, des grandes tendances et interrogations en philosophie, mais également, à partir de quelques coups de sonde très diversifiés - sur (...) l'éthique universaliste, les droits de l'homme, les nouvelles formes de rationalité scientifique, les rapports entre le langage et l'esprit ou bien encore l'enseignement comparé de la philosophie en Europe -, une des interrogations philosophiques entre pays, donc du dialogue pourtant nécessaire entre penseurs et intellectuels, par-delà les frontières nationales et culturelles. Au terme de cet étonnant voyage au pays des concepts, la conclusion inéluctable est bien : " Philosophes, encore un effort pour être européens... ". (shrink)

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

For the epic journey of autumn migration, long-distance migratory birds use innate and learned information and follow strict schedules imposed by genetic and epigenetic mechanisms, the details of which remain largely unknown. In addition, bird migration requires integrated action of different multisensory systems for learning and memory, and the hippocampus appears to be the integration center for this task. In previous studies we found that contrasting long-distance migratory flights differentially affected the morphological complexity of two types of hippocampus astrocytes. Recently, (...) a significant association was found between the latitude of the reproductive site and the size of the ADCYAP1 allele in long distance migratory birds. We tested for correlations between astrocyte morphological complexity, migratory distances, and size of the ADCYAP1 allele in three long-distance migrant species of shorebird and one non-migrant. Significant differences among species were found in the number and morphological complexity of the astrocytes, as well as in the size of the microsatellites of the ADCYAP1 gene. We found significant associations between the size of the ADCYAP1 microsatellites, the migratory distances, and the degree of morphological complexity of the astrocytes. We suggest that associations between astrocyte number and morphological complexity, ADCYAP1 microsatellite size, and migratory behavior may be part of the adaptive response to the migratory process of shorebirds.

In this volume, Pears examines the internal organization of Wittgenstein's thought and the origins of his philosophy to provide unusually clear insight into the philosopher's ideas. Part I surveys the whole of Wittgenstein's work, while Part II details the central concepts of his early system; both reveal how the details of Wittgenstein's work fit into its general pattern.

This book is about self-deception and lack of self-control or wishful thinking and acting against one's own better judgement. Steering a course between the skepticism of philosophers, who find the conscious defiance of reason too paradoxical, and the tolerant empiricism of psychologists, it compares the two kinds of irrationality, and relates the conclusions drawn to the views of Freud, cognitive psychologists, and such philosophers as Aristotle, Anscombe, Hare and Davidson.

Since its publication in 1959, Individuals has become a modern philosophical classic. Bold in scope and ambition, it continues to influence debates in metaphysics, philosophy of logic and language, and epistemology. Peter Strawson's most famous work, it sets out to describe nothing less than the basic subject matter of our thought. It contains Strawson's now famous argument for descriptive metaphysics and his repudiation of revisionary metaphysics, in which reality is something beyond the world of appearances. Throughout, Individuals advances some highly (...) influential and controversial ideas, such as 'non-solipsistic consciousness' and the concept of a person a 'primitive concept'. (shrink)

This is the first of David Pears's acclaimed two‐volume work on the development of Wittgenstein's philosophy, covering the pre‐1929 writings. Part I of the first volume consists in a brief but eloquent overview of Wittgenstein's philosophy as a whole; Part II critically examines the earlier system, delineating and evaluating the central ideas (logical atomism, picture theory of meaning, and solipsism) with intellectual rigour and clarity. Pears succeeds in both offering an original realist interpretation of Wittgenstein's earlier thought, (...) one that has found many followers, and in demarcating a structural framework that makes the internal organization of Wittgenstein's philosophy as a whole more accessible.

This is a concise and readable study of five intertwined themes at the heart of Wittgenstein's thought, written by one of his most eminent interpreters. David Pears offers penetrating investigations and lucid explications of some of the most influential and yet puzzling writings of twentieth-century philosophy. He focuses on the idea of language as a picture of the world; the phenomenon of linguistic regularity; the famous "private language argument"; logical necessity; and ego and the self.

This is the second of David Pears's acclaimed two‐volume work on the development of Wittgenstein's philosophy, covering the Philosophical Investigations and other writings from 1929 onwards. Though more selective in its coverage than the first volume (it deals mainly with Wittgenstein's philosophy of psychology and the ego, the possibility of a private language and rule‐following), the book reveals with great clarity the style, method, and content of Wittgenstein's later thought. While this volume is independently comprehensible, Pears remains (...) largely within the structural framework of the first volume and uncovers thereby the general overall configuration and internal organization of Wittgenstein's thought.

A stellar group of philosophers offer new works on themes from the great philosophy of Wittgenstein, honoring one of his most eminent interpreters David Pears. This collection covers both the early and the later work of Wittgenstein, relating it to current debates in philosophy. Topics discussed include solipsism, ostension, rules, necessity, privacy, and consciousness.

Ludwig Wittgenstein was born in Vienna in 1889 and died in Cambridge in 1951. He studied engineering, first in Berlin and then in Manchester, and he soon began to ask himself philosophical questions about the foundations of mathematics. What are numbers? What sort of truth does a mathematical equation possess? What is the force of proof in pure mathematics? In order to find the answers to such questions, he went to Cambridge in 1911 to work with Russell, who had just (...) produced in collaboration with Whitehead (1861-1947) Principia Mathematica (1910-1913), a monumental treatise which bases mathematics on logic. But on what is logic based? Wittgenstein's attempt to answer this question convinced Russell that he was a genius. During the 1914-8 war he served in the Austrian army and in spare moments continued the work on the foundations of logic which he had begun in 1912. His war-time journal, Notebook s 1914-16 (1961), reveals the development of his ideas more clearly that the final version, Tractatus Logico- Philosophicus, which he published in the early 1920s.

In this compelling analysis David Pears examines the foundations of Hume's theory of the mind as presented in the first book of the Treatise. Past studies have tended to take one of two extreme views: that Hume relies exclusively on a theory of meaning, or that he relies exclusively on a theory of truth and evidence. Steering a middle course between these positions, Pears argues that Hume's theory of ideas serves both functions. He examines in detail its (...) application to three difficult problems: causation, personal identity, and sense perception. Hume's solutions, Pears argues, are not theories that can be given a place in standard classification of philosophical theories, but rather depend upon a subtle form of naturalism not altogether unlike Wittgenstein's naturalism. A clearly written and argued study, Hume's System will be of special interest to students and scholars of the history of philosophy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XIX, Number 2, November 1993, pp. 289-299 Hume on Personal Identity DAVID PEARS The question that I discuss in this paper has often been raised and it has been answered in many different ways. "Why did Hume retract his theory of personal identity?" He puts it forward in the main text of the Treatise with his usual panache, and then takes it back in (...) the Appendix. Why? Many different answers have been given to this question and what most of them have in common is the confidence with which they are given. Each interpreter sticks to his own interpretation in spite of the plausibility of its rivals, few of which are actually excluded by what Hume says. For this is an extreme case of the underdetermination of interpretation by evidence. I confess that in spite of all the recent work on this subject, I remain loyal to my own suggestion, which I first made in 1975.1 I will start with a sketch of my interpretation. Then I will quote Hume's recantation and develop an argument for my interpretation, based on that text and on others. After that, I will show how my suggestion is related to some of its rivals and I will say something about their comparative merits. Naturally, there is a considerable amount of overlap between the more plausible answers to the question, why Hume recanted. 1. My Interpretation In his Appendix, Hume confesses that his theory of personal identity seems to him to understate the strength of the connections between the David Pears is Emeritus Professor of Philosophy, Oxford University. 290 David Pears impressions and ideas that constitute a single person; or, as I would prefer to express his doubts, the impressions and ideas that constitute a single person's mind. He says that he would have been content if he could have attributed all those perceptions to a single substance; or alternatively, if he could have found some real connection between them. But all that he can find are connections based on the three natural relations: resemblance, contiguity, and causation. And those connections are, he implies, not enough. It is certain that he is thinking of a fundamental difficulty. For he evidently sees some reason for doing something which is simply not possible within his system, namely finding stronger connections between perceptions than those allowed by the doctrine of the main text of the Treatise. But what is his fundamental difficulty? The suggestion that I put forward was this: when an impression of sense occurs in my series of perceptions, it does not hold its place in the series by possessing any property, or by standing in any specific relation to any other perception in the series (except, of course, the relation of being co-experienced). Consequently, when I review the series, I do not find that the sensation is anchored by anything other than the fact of its contingent occurrence at the point where it occurred. Nevertheless, there is a strong modal statement that can be made about it: It, the very same sensation, could not conceivably have occurred in any other series. This modal statement is based on the special character of the identity-line of a particular perception: the identity-line of a particular perception starts at the point where it occurs in a particular series, and no sense can be attached to the speculation that it, the very same perception, might have occurred in some other series. However, in Hume's system, perceptions are treated like stars which form constellations, but only form them contingently, and it is obvious that the discovery of additional contingent relations between perceptions would never provide any support for the strong modal statement. Yet in Hume's system the only possible relations between perceptions are contingent relations. The other alternative, that the self is a substance, would, perhaps, do the trick, but for Hume it is unthinkable. It may seem fanciful to suggest that Hume's problem was the difficulty of accounting for the necessary ownership of perceptions within the framework of his system. But it is hard to see what other reason he could have had for requiring stronger relations... (shrink)

There are several kinds of philosophical naturalism and one of their leading ideas is that the right method in philosophy is not to theorize about things but to describe them as we find them in daily life. Wittgenstein’s later philosophy is evidently a naturalism inspired by this idea. However, that is an observation which leaves much unexplained. It is a simple key which unlocks the first door only to reveal others behind it that remain closed.
