Que veut dire « vivre de sa plume»? L'expression a souvent été invoquée par des historiens avançant le récit d'un progrès dans les pratiques littéraires marqué par le passage des écrivains du patronage au marché, afin de définir la « modernité » auctoriale par rapport à un modèle ancien de l'homme de lettres protégé par la noblesse. Or un examen plus attentif montrera que ce progrès vers une autonomie gagnée par la vente des écrits n'est guère aussi évident qu'on a (...) eu tendance à le croire. Cet article étudie donc les ambiguïtés du récit historique implicite dans la notion de « vivre de sa plume ». Il propose ensuite une approche différente qui considère cette représentation non pas comme le reflet d'une nouvelle réalité professionnelle, mais comme un élément dans une nouvelle rhétorique de la présentation de soi en tant qu 'intellectuel. Comme topos, l'image va désigner - et en fait, constituer - à la fois la libération sociale de l'auteur à l'égard de la noblesse et son autorité morale lorsque ses tentatives de vivre de ses écrits échouent et qu'il persiste tout de même à sacrifier son bonheur personnel à son art.

Hellman and Shapiro explore the development of the idea of the continuous, from the Aristotelian view that a true continuum cannot be composed of points to the now standard, entirely punctiform frameworks for analysis and geometry. They then investigate the underlying metaphysical issues concerning the nature of space or space-time.

A visual imagery task is presented which is beyond the limits of normal human ability, and some of the factors contributing to its difficulty are isolated by comparing the difficulty of related tasks. It is argued that complex objects are assigned hierarchical structural descriptions by being parsed into parts, each of which has its own local system of significant directions. Two quite different schemas for a wire‐frame cube are used to illustrate this theory, and some striking perceptual differences to which (...) they give rise are described. The difficulty of certain mental imagery tasks is shown to depend on which of the alternative structural descriptions of an object is used, and this is interpreted as evidence that structural descriptions are an important component of mental images. Finally, it is argued that analog transformations like mental folding involve changing the values of continuous variables in a structural description. (shrink)

The present work is a systematic study of five frameworks or perspectives articulating mathematical structuralism, whose core idea is that mathematics is concerned primarily with interrelations in abstraction from the nature of objects. The first two, set-theoretic and category-theoretic, arose within mathematics itself. After exposing a number of problems, the book considers three further perspectives formulated by logicians and philosophers of mathematics: sui generis, treating structures as abstract universals, modal, eliminating structures as objects in favor of freely entertained logical possibilities, (...) and finally, modal-set-theoretic, a sort of synthesis of the set-theoretic and modal perspectives.

It is possible to learn multiple layers of non-linear features by backpropagating error derivatives through a feedforward neural network. This is a very effective learning procedure when there is a huge amount of labeled training data, but for many learning tasks very few labeled examples are available. In an effort to overcome the need for labeled data, several different generative models were developed that learned interesting features by modeling the higher order statistical structure of a set of input vectors. One (...) of these generative models, the restricted Boltzmann machine (RBM), has no connections between its hidden units and this makes perceptual inference and learning much simpler. More significantly, after a layer of hidden features has been learned, the activities of these features can be used as training data for another RBM. By applying this idea recursively, it is possible to learn a deep hierarchy of progressively more complicated features without requiring any labeled data. This deep hierarchy can then be treated as a feedforward neural network which can be discriminatively fine-tuned using backpropagation. Using a stack of RBMs to initialize the weights of a feedforward neural network allows backpropagation to work effectively in much deeper networks and it leads to much better generalization. A stack of RBMs can also be used to initialize a deep Boltzmann machine that has many hidden layers. Combining this initialization method with a new method for fine-tuning the weights finally leads to the first efficient way of training Boltzmann machines with many hidden layers and millions of weights.

Standard proofs of generalized Bell theorems, aiming to restrict stochastic, local hidden-variable theories for quantum correlation phenomena, employ as a locality condition the requirement of conditional stochastic independence. The connection between this and the no-superluminary-action requirement of the special theory of relativity has been a topic of controversy. In this paper, we introduce an alternative locality condition for stochastic theories, framed in terms of the models of such a theory (§2). It is a natural generalization of a light-cone determination condition (...) that is essentially equivalent to mathematical conditions that have been used to derive Bell inequalities in the deterministic case. Further, it is roughly equivalent to a condition proposed by Bell that, in one investigation, needed to be supplemented with a much stronger assumption in order to yield an inequality violated by some quantum mechanical predictions. It is shown here that this reflects a very general situation: from the proposed locality condition, even adding the strict anticorrelation condition and the auxiliary hypotheses needed to derive experimentally useful (and theoretically telling) inequalities, no Bell-type inequality is derivable. (These independence claims are the burden of §4.) A certain limitation on the scope of the proposed stochastic locality condition is exposed (§5), but it is found to be rather minor. The conclusion is thus supported that conditional stochastic independence, however reasonable on other grounds, is essentially stronger than what is required by the special theory.Our results stand in apparent contradiction with a class of derivations purporting to obtain generalized Bell inequalities from locality alone. It is shown in Appendix (B) that such proofs do not achieve their goal. This fits with our conclusion that generalized Bell theorems are not straightforward generalizations of theorems restricting deterministic hidden-variable theories, and that, in fact, such generalizations do not exist. This leaves open the possibility that a satisfactory, non-deterministic account of the quantum correlation phenomena can be given within the framework of the special theory. (shrink)

Although the mathematization of nature is a distinctive and crucial feature of the emergence of modern science in the seventeenth century, this volume shows that it was a far more complex, contested, and context-dependent phenomenon than the received historiography has indicated.0.

Descartes' account of the material world relies heavily on time. Most importantly, time is a component of speed, which figures in his fundamental conservation principle and laws. However, in his most systematic discussion of the concept, time is treated as some-how reducible both to thought and to motion. Such reductionistic views, while common among Descartes' late scholastic contemporaries, are very ill-suited to Cartesian physics. I show that, in spite of the apparent identifications with thought and motion, Cartesian time retains—in the (...) form of what I will call 'successive duration'—precisely the intrinsic structure necessary to serve as an independent parameter of quantitative physics. As is often the case with Descartes, he gives the impression of embracing traditional doctrines while in fact radically transforming the underlying concepts to serve his scientific agenda. His theory of time, though formulated in Aristotelian terms, anticipates Newton in important respects. (shrink)

Eye movements were recorded during the display of two images of a real-world scene that were inspected to determine whether they were the same or not . In the displays where the pictures were different, one object had been changed, and this object was sometimes taken from another scene and was incongruent with the gist. The experiment established that incongruous objects attract eye fixations earlier than the congruous counterparts, but that this effect is not apparent until the picture has been (...) displayed for several seconds. By controlling the visual saliency of the objects the experiment eliminates the possibility that the incongruency effect is dependent upon the conspicuity of the changed objects. A model of scene perception is suggested whereby attention is unnecessary for the partial recognition of an object that delivers sufficient information about its visual characteristics for the viewer to know that the object is improbable in that particular scene, and in which full identification requires foveal inspection.

The Spanish philosopher Miguel de Unamuno and the American social scientist Ernest Becker see death as humanity’s fundamental anxiety. My essay explores the ethical ramifications attendant upon making that anxiety a well-spring of human activity. More specifically, I am interested in humanity’s effort to escape death via the secular milieu of social remembrance. Does such an effort produce a vista where the other exhibits an intrinsic value? Alternatively, does the other become a mere means in light of one’s project of (...) self-preservation? Pursuing such questions, this reflection will explore both positive and negative responses. It will take up the Columbine school shootings in reference to the latter and a notion of protest with regard to the former. The treatise will culminate with a discussion of Unamuno’s ethics of irreplaceability and its potential to engender a universal human respect while also endorsing one’s commitment to her concrete individuality.

How would a liberation theologian respond to Marx’s famous critique that religious belief and, even more specifically, a hope for heaven is “the opium of the people”? I utilize the conceptual resources found within the work of liberation theologians Gustavo Gutiérrez, Enrique Dussel, and Jon Sobrino to argue that a belief in heaven is able to constitute a protest against oppressed persons’ present hell. To strengthen the connection between a believer’s heavenly hope and a commitment to worldly struggle, I examine (...) how the hope must be conceived as the completion and fulfillment of a process of temporal transformation.

La création d’un système de santé public a été l’un des éléments clés de la Révolution tranquille dans les années 1960 au Québec. Toutefois, le développement de nouveaux traitements et de nouvelles technologies, en particulier des produits pharmaceutiques, ont fait naître un nouveau débat sur la gestion de notre système de santé. En se basant sur une analyse récente des valeurs libérales dans la société québécoise par Claude Ryan, l’auteur souligne l’importance que le gouvernement doit accorder à ces valeurs dans (...) la modernisation de notre système de santé. À la lumière des recommandations présentées par la commission Clair au provincial et par la commission Romanow au fédéral, la situation se prête bien à une modernisation du système de soins au Québec. Les valeurs libérales ont fourni une base au système de santé public ; elles sont plus pertinentes qu’elles ne l’ont jamais été alors que le débat sur notre système de santé est engagé. (shrink)

On Civic Republicanism explores the enduring relevance of the ancient concepts of republicanism and civic virtue to modern questions about political engagement and identity.".

Quantum logic as genuine non-classical logic provides no solution to the "paradoxes" of quantum mechanics. From the minimal condition that synonyms be substitutable salva veritate, it follows that synonymous sentential connectives be alike in point of truth-functionality. It is a fact of pure mathematics that any assignment Φ of (0, 1) to the subspaces of Hilbert space (dim. ≥ 3) which guarantees truth-preservation of the ordering and truth-functionality of QL negation, violates truth-functionality of QL ∨ and $\wedge $ . Thus, (...) from within both the classical framework and that of any QL that preserves elementary set theory, two distinct (nonsynonymous) sets of connectives are discernible. Classical derivations of QM paradoxes are all available unless the language of QM is not classically closed. Maintaining this requires a strong and selfdefeating verification theory of meaning, the philosophical cornerstone of the Copenhagen interpretation to which QL was to provide an alternative.

In a recent paper, while discussing the role of the notion of analyticity in Carnap’s thought, Howard Stein wrote: “The primitive view–surely that of Kant–was that whatever is trivial is obvious.

This book takes the thinking of Quentin Skinner, Philip Pettit and J. G. A. Pocock on republican liberty and explores the way in which this idea of liberty can be used to illuminate educational practice. It argues that republican liberty is distinct from both positive and negative liberty, and its emphasis on liberty as non-dependency gives the concept of liberty a particularly critical role in contemporary society. Each chapter formulates and expounds the idea that an empire of liberty requires the (...) existence of what are termed 'liberty-bearing agents', and shows how education - with a particular emphasis on knowledge - is needed to foster the human powers which allow people to become liberty-bearing. It is also emphasised, however, that republican liberty is non-perfectionist and non-eudaimonic: the core values enshrined in an empire of liberty centre on non-dependency rather than the promulgation of a certain way of life. Drawing on prominent seventeenth century contract theorists, the link between liberty and authority is explained, suggesting that appropriate authoritative structures need to underpin the provision of education, and especially schooling, if educational practice devoted to the pursuit of liberty is to flourish. Liberty and Education will be of value to both educational theorists unfamiliar with republican theory, as well as republican theorists interested in how their theory might play out in education. It will also be of interest to researchers and students from the fields of politics and the philosophy of education. (shrink)

Amartya Sen reconsiders the idea of 'the standard of living'. He rejects the more conventional economic interpretations in terms of 'unity' and of wealth or 'opulence', and suggests an interpretation in terms of the 'capabilities and freedoms' that states of affairs do or do not allow. His argument is conceptual, but it refers to a wide range of examples. In elaborations of it, John Muellbauer explains how parts of it might be applied; Ravi Kanbur discusses the difficulties raised by choice (...) ex ante, under uncertainty, and choice ex post; Keith Hart discusses the ways in which one might think about living standards in societies in which there is a substantial amount of what he calls 'self provisioning' outside the market; and Bernard Williams reflects on some of the moral and political implications of Sen's argument. There is a bibliography of most of the more important works on the subject. The book will be of interest to economists, sociologists, students of development and moral and political philosophers; it will also be of interest to those concerned with public policy. (shrink)

Western civilization has probably reached an impasse, expressed as a crisis on all fronts: economic, technological, environmental and political. This is experienced on the cultural level as a moral crisis or an ethical deficit. Somehow, the means we have always assumed as being adequate to the task of achieving human welfare, health and peace, are failing us. Have we lost sight of the primacy of human ends? Governments still push for economic growth and technological advances, but many are now asking: (...) economic growth for what, technology for what? Health care and nursing are caught up in the same inversion of human priorities. Professionals, such as nurses and midwives, need to take on social responsibilities and a collective civic voice, and play their part in a moral regeneration of society. This involves carrying civic rights and duties into the workplace. (shrink)

Journal of Philosophy of Education, EarlyView.

In the second half of 1944, Jean-Paul Sartre wrote an essay entitled ‘Anti-Semite and Jew’. He analyses what might be termed the moral pathology of the anti-Semite. Such a person, Sartre suggests, has chosen to enact a passion, a passion of hatred. The motive is the desire for ‘impenetrability’ – a disavowal of reasoned argument – and a pleasure taken in the assertion and re-assertion of what is known to be false. Sartre’s essay was written hurriedly and looking back over (...) 70 years, we can see its flaws. But I suggest that the kernel of his analysis of the anti-Semite is compelling, especially in the context of the growth of anti-immigrant prejudice in the UK and elsewhere. Using Sartre as a starting point, I discuss the nature of prejudice and suggest that to counter prejudices, a civic education is needed that emphasises a narrative of liberty. (shrink)

This paper considers the nature of academic judgement. It also suggests that academic judgement is not the special preserve of academics as such and is something with which students can be imbued. It is further suggested that academic judgement is best considered in the context of critical learning which is contrasted with demonstrative learning. The paper then proceeds with an analysis of judgement by considering the ideas of Peter Geach on this particular subject. It then moves to considering judgement in (...) the context of a practice, as set out by Alasdair MacIntyre. Whilst providing insight into the nature of practical judgement, this approach is found wanting nonetheless and attention is next turned to considering judgement within the space of reasons – that is, the approach of John McDowell. The paper then suggests that the idea of the space of reasons can be given greater substance through consideration of two further kinds of judgement – epistemic and reflective. (shrink)

An acclaimed critical history of social theory from the eighteenth century onwards.

After some introductory remarks on "experimental metaphysics", a brief survey of the current situation concerning the major types of hidden-variable theories and the inexistence proofs is presented. The category of stochastic, contextual, local theories remains open. Then the main features of a logical analysis of "locality" are sketched. In the deterministic case, a natural "light-cone determination" condition helps bridge the gap that has existed between the physical requirements of the special theory of relativity and formal conditions used in proving the (...) Bell -Wigner theorem. Natural generalization to the stochastic type, taking account of the distinction between epistemic and physical probabilities, leads to a series of independence claims constituting some significant limitations on generalized Bell theorems. In particular, the conditional stochastic independence requirement is seen both to go beyond the demand of compliance with the STR and to be a genuine necessity in deriving any Bell theorem for the stochastic case. The conclusion is also supported that, if determinism is given up, the Bell theorems and experiments do not pose an additional obstacle to unifying relativity theory and quantum mechanics beyond what is already posed by the "instantaneous" collapse of the wave function.

Ethical disputes arise over differences in the content of the ethical beliefs people hold on either side of an issue. One person may believe that it is wrong to have an abortion for financial reasons, whereas another may believe it to be permissible. But, the magnitude and difficulty of such disputes may also depend on other properties of the ethical beliefs in question—in particular, how objective they are perceived to be. As a psychological property of moral belief, objectivity is relatively (...) unexplored, and we argue that it merits more attention. We review recent psychological evidence which demonstrates that individuals differ in the extent to which they perceive ethical beliefs to be objective, that some ethical beliefs are perceived to be more objective than others, and that both these sources of variance are somewhat systematic. This evidence also shows that differences in perceptions of objectivity underpin quite different psychological reactions to ethical disagreement. Apart from reviewing this evidence, our aim in this paper is to draw attention to unanswered psychological questions about moral objectivity, and to discuss the relevance of moral objectivity to two issues of public policy.

In an imagined dialogue between two figures called “Carnap*” and “Quine*” that appeared in the Library of Living Philosophers volume in 1986, certain proposals and clarifications of the linguistic doctrine were offered by Carnap* answering Quinean objections, but these were brushed aside rather breezily in a reply to this dialogue in the same volume by Quine himself. After a brief summary of the questions at issue in that earlier dialogue, Carnap* is here allowed a final reply, introducing yet another variant (...) on his series of more precise formulations of the linguistic doctrine of logical truth and touching on other issues raised both by Quine* in the earlier dialogue and by Quine himself in his reply.
