This book is a long-term history of optics, from early Greek theories of vision to the nineteenth-century victory of the wave theory of light. It is a clear and richly illustrated synthesis of a large amount of literature, and a reliable and efficient guide for anyone who wishes to enter this domain.

Digital reading devices such as Kindle differ from paper books with respect to the kinesthetic and tactile feedback provided to the reader, but the role of these features in reading is rarely studied empirically. This experiment compares reading of a long text on Kindle DX and in print. Fifty participants (24 years old) read a 28 page (approx. one hour reading time) long mystery story on Kindle or in a print pocket book and completed several tests measuring various (...) levels of reading comprehension: engagement, recall, capacities to locate events in the text and reconstructing the plot of the story. Results showed that in most tests subjects performed identically whatever the reading medium. However, on measures related to chronology and temporality, those who had read in the print pocket book, performed better than those who had read on a Kindle. It is concluded that, basically comprehension was similar with both media, but, because kinesthetic feedback is less informative with kindle, readers were not as efficient to locate events in the space of the text and hence in the temporality of the story. We suggest that, to get a correct spatial representation of the text and consequently a coherent temporal organization of the story, readers would be reliant on the sensorimotor cues which are afforded by the manipulation of the book.

If we consider heritage as a process of exhibiting the past and the present to present these for future observers then encyclopedias are good candidates for assessing what constitutes heritage. We propose to study the Fluxion entries in British encyclopaedias over a long period of time. With the help of this corpus of more than thirty articles, it will then be possible to identify several markers that contribute to making mathematics a heritage object—a reference to history, sources of inspiration (...) and bibliographical references.

A long-standing debate has dominated systematic biology and the ontological commitments made by its theories. The debate has contrasted individuals and the part – whole relationship with classes and the membership relation. This essay proposes to conceptualize the hierarchy of higher taxa is terms of a hierarchy of homeostatic property cluster natural kinds (biological species remain largely excluded from the present discussion). The reference of natural kind terms that apply to supraspecific taxa is initially fixed descriptively; the extension of (...) those natural kind terms is subsequently established by empirical investigation. In that sense, classification precedes generalization, and description provides guidance to empirical investigation. The reconstruction of a hierarchy of (homeostatic property cluster) natural kinds is discussed in the light of cladistic methods of phylogeny reconstruction. (shrink)

The objective of this paper is to explore how the various stages of consciousness development of top managers can influence, in practical terms, their abilities in and commitment to environmental leadership in different types of SMEs. A case study based on 63 interviews carried out in 15 industrial SMEs showed that the organizations that displayed the most environmental management practices were mostly run by managers at a post-conventional stage of consciousness development. Conversely, the SMEs that displayed less sustainable environmental management (...) practices were all run by managers at conventional stages of development. Drawing upon diverse examples of environmental leadership, this paper analyzes the reasons why the stages of post-conventional consciousness development of top managers seem to foster corporate greening in SMEs. The study also sheds light on the key values and abilities associated with both environmental leadership and the upper-stages of consciousness development, which include a broader and systemic perspective, long-range focus, integration of conflicting goals, collaboration with stakeholders, complexity management, collaborative learning, among others.

En 1741, la Royal Military Academy de Woolwich est créée par le Board of Ordnance afin d’instruire les futurs artilleurs et ingénieurs militaires. Cette instruction s’appuie dès le départ sur les mathématiques. Dans cet article, nous présentons et étudions les différents programmes sur la longue période (entre 1741 et les années 1860). Les évolutions, les changements mais aussi les constances sont évalués et nous donnons les raisons de ceux-ci. L’âge de recrutement, le poids du Board of Ordnance ou encore les (...) diverses guerres ont aussi une influence importante sur la place des mathématiques dans les programmes. Par ailleurs, le peu de turn-over des professeurs entraîne aussi une inertie de l’enseignement des mathématiques. In 1741, the Royal Military Academy at Woolwich was created by the Board of Ordnance in order to instruct artillery officers and military engineers. From the beginning, the teaching was mainly based on mathematics. In this paper, we study different curricula and point out the long-term (between 1741 and the 1860s) evolution as well as continuity in mathematical learning and we give reasons for them. The age of recruitment, the authority of the Board of Ordnance and several wars had an influence on the role of mathematics in the syllabus. Furthermore, the low turnover of professors led to inertia in the teaching of mathematics. (shrink)

The docility hypothesis holds that human social learning produces genuinely altruistic behaviors as a maladaptive by-product. This article examines five possible sources of such altruistic mistakes. The first two mechanisms, the smoke-detector principle and the cost-accuracy tradeoff, are not specifically linked to social learning. Both predict that it may be adaptive for cooperators to allow some altruistic mistakes to happen, as long as those mistakes are rare and cost little. The other three mechanisms are specific to social learning: Through (...) culture, individuals may come to adopt altruistic norms selected at the group level. Culture may provide people with cheap, accessible, but occasionally mediocre information that they are too reliant upon—a kind of informational dumping. Lastly, people may copy sources good to follow in one domain but not in another, thus committing calibration errors. I argue that those sources of errors are unlikely to lead to important amounts of altruism toward non-kin. Experimental evidence shows humans to be sufficiently skeptical, discriminative, and conscious of their own interest to avoid such altruistic mistakes in most cases. Docile altruism is unlikely to be an important aspect of human cooperation. (shrink)

" Se moquer de la philosophie, c'est vraiment philosopher. " Ce propos de Pascal, Olivier Bloch l'illustre et le confirme par le présent ouvrage, en s'attachant à démontrer la part de philosophie inhérente au texte de Molière et le jeu théâtral auquel elle renvoie. La philosophie, dont le terme et le concept courent tout au long de l'œuvre de Molière, c'est celle de son temps, au premier chef celle de Descartes, mais aussi les philosophies antagonistes comme celle de (...) Gassendi. L'étude d'Olivier Bloch nous montre que les pièces les plus célèbres de Molière - Dom Juan, Les Femmes Savantes, Tartuffe... comme d'autres moins connues - Amphitryon, Les Amants magnifiques... - mettent littéralement en scène des propos, des débats et des concepts caractéristiques de ces philosophies. Ce constat n'a rien d'anecdotique : nous découvrons ainsi que Molière avait une connaissance et une compréhension des problèmes philosophiques de son époque qui dépassent ce que l'on avait soupçonné jusqu'alors. Sur le registre de l'humour, il détourne à travers ses pièces les thèmes philosophiques majeurs de l'époque classique (Dieu et les preuves de son existence, l'âme et le corps, le Moi, etc.) et fait écho à leur mise en cause dans la Culture du XVIIe siècle. Lecture originale et subtile de Molière, cet essai éclaire son œuvre, les débats de son époque et les rapports qu'entretiennent la littérature, le théâtre, la comédie, le rire et la philosophie.

Textbooks and manuals on management suggest that managers are heroes who deal with difficult problems of collective adaptation and change. American films are similarly built on the premise of a hero confronted with extremely difficult situations. What if this hero figure promoted for so long in both management literature and the American film industry was the same at the structural level? This paper will attempt to clearly define the ethical performance of heroes that is perhaps shared by the imagination (...) industry and the workplace on the long run. We shall follow this picture of a hero-leader in the ethics of business and cinema through a large corpus of movies and writings on management and provide a set of six features for examining both, a common heroic structure we shall call the Hero-Leader Matrix.

Le réductionnisme consiste en la thèse selon laquelle toute entité Y « se réduit », ou est en principe « réductible », à une entité unique de base (ou un ensemble unique d’entités de base) X(i). Ceci étant, la thèse du réductionnisme ne peut être rendue intelligible qu’au travers d’une explicitation première de ce en quoi consiste la « réduction » de Y à X(i). Une telle explicitation s’opère le long de deux dimensions, l’une associée à la nature des (...) relata de la réduction, l’autre à la nature de la relation de réduction. Lorsque les relata de la réduction ressortissent à nos modalités de représentation du monde naturel, on parle de réductionnisme épistémologique, dont les deux variétés les plus répandues sont les réductionnismes théorique et explicatif. L’enjeu de cette première famille de réductionnisme consiste essentiellement à savoir si notre connaissance du monde peut en principe prendre la forme d’un discours unifié ou, au contraire, se révèle inexorablement fragmentée. Lorsque les relata de la réduction ressortissent aux entités qui peuplent le monde naturel lui-même, on parle plutôt de réductionnisme ontologique, dont une sous-variété sensible est le réductionnisme causal, c’est-à-dire, en substance, la thèse selon laquelle les pouvoirs causaux naturels, comme les pouvoirs vivants, mentaux ou sociaux, ne sont en réalité que des combinaisons de pouvoirs physiques sous-jacents. Relativement à cette seconde famille de réductionnisme, l’enjeu principal consiste en la défense de la spécificité, et d’ailleurs aussi de l’existence même, de réalités supérieures, telles que, par exemple, le libre arbitre humain.

In this paper, we put forward a new account of emergence called “transformational emergence”. Such an account captures a variety of emergence that can be considered as being diachronic and weakly ontological. The fact that transformational emergence actually constitutes a genuine form of emergence is motivated. Besides, the account is free of traditional problems surrounding more usual, synchronic versions of emergence, and it can find a strong empirical support in a specific physical phenomenon, the fractional quantum Hall effect, which has (...) long been touted as a paradigmatic case of emergence.

Efficiency principles are increasingly called upon to study features of human language and communication. Zipf's law of abbreviation is widely seen as a classic instance of a linguistic pattern brought about by language users’ search for efficient communication. The “law”—a recurrent correlation between the frequency of words and their brevity—is a near-universal principle of communication, having been found in all of the hundreds of human languages where it has been tested, and a few nonhuman communication systems as well. The standard (...) explanation for the law of abbreviation derives from pressures for efficiency: speakers minimize their cumulative effort by using shorter words for frequent occurrences. This explanation, we argue here, fails to explain why long words exist at all. It also fails to explain why the law of abbreviation, despite being robust, is systematically weakened by many short and rare words. We propose an alternative account of the law of abbreviation, based on a simple cultural evolutionary model. Our model does not require any pressure for efficiency. Instead, it derives the law of abbreviation from a general pressure for brevity applying to all words regardless of their frequency. This model makes two accurate predictions that the standard model misses: the correlation between frequency and brevity is consistently weak, and it is characterized by heteroskedasticity, with many short and rare words. We argue on this basis that efficiency considerations are neither necessary nor sufficient to explain the law. (shrink)

In his recent book, the well-known Cypriote scholar K. Hadjioannou comes back to a disputed verse of Nonnus, Dionysiaca 13.432. For a long time the usual text has mentioned two obscure Cypriote heroes, Litros and Lapethos: Κνπριδας δ φλαγγας κσμεε Λτρος γνωρ | εχατης τε Λπηθος. Obviously the second is the legendary eponym of the town of Lapethus . But what are we to say of the first one, Litros? Hitherto the name is unknown, either for a figure or (...) for a city. Nevertheless we know something which is not very different, in the ancient name of Λδρα, Λδρα, previous designation of the modern city of Nicosia, which was for a few centuries the capital of a small kingdom in central Cyprus. Thus, independently, Pierre Chuvin in his study of the geography of Nonnus and the present writer in a detailed discussion of the name of Ledra, etc., both put forward the hypothesis that ‘Λτρος’ is nothing but a light distortion of Λδρος, which could simply be the eponymous hero of the city . As P. Chuvin observes: ‘Les deux formes sont pratiquement homophones: Lapéthos et Lèdros auraient été fabriqués de la même façon’. We thus think that the easy correction here is not misplaced. But now K. Hadjioannou objects that the poet did not allude to the town of Ledra and that the singular κσμεε cannot support two subjects. On the first point I would answer that the poet is not obliged to afford symmetrical allusions, on the second that the verb is here correctly in agreement with the nearest subject . And what does our Cypriote colleague propose? Another kind of correction by which the first hero completely disappears in favour of a new epithet of Lapethos, the text being; κσμεε λνγρς, γνωρ/εχατης τε Λπηθος. The idea is indeed ingenious, but does not convince: the rather negative adjective λνγρς. (shrink)

Olivier Tinland | : Dans cet article, je me propose de clarifier la manière dont Jürgen Habermas utilise le terme « quasi-transcendantal » dans l’ensemble de son oeuvre.

Le projet de recherche collaborative intitulé TRACS ( Transatlantic Cultures. Cultural Histories of the Atlantic World 18th – 21st Centuries ) vise à élaborer une plate-forme numérique encyclopédique afin de mettre en œuvre une histoire des circulations culturelles dans l’espace atlantique à l’époque contemporaine dans une perspective pluridisciplinaire associant historiens, anthropologues, sociologues, géographes, musicologues, spécialistes de littérature, d’arts, de théâtre ou encore de cinéma. Si le premier objectif du projet est de décrypter l’économie complexe des échanges entre l’Europe, l’Afrique et (...) les Amériques entre la fin du XVIII et le début du XXI siècles en partant du postulat selon lequel le monde atlantique a été un laboratoire privilégié de la mondialisation culturelle, il propose également une réflexion sur les processus identitaires et les frontières qui ont contribué à l’établissement et à la reconfiguration des grandes aires culturelles, ainsi que sur les régimes circulatoires des pratiques, des savoirs et des représentations d’une rive à l’autre de l’océan sur le temps long des 250 dernières années. Pour mener à bien notre démonstration, nous aborderons trois aspects essentiels : le premier tient à la définition même de l’espace atlantique, à ses lignes de forces et à ses frontières ; le second concerne les temporalités de son histoire, longtemps restreinte à l’époque moderne ; le troisième relève des objets étudiés et de la spécificité de l’histoire culturelle, conçue comme une histoire sociale des représentations, des pratiques et des productions symboliques, face à des approches de nature géopolitique et aux Cultural Studies.

The academic path of Jean Gayon (1949–2018) follows in the wake of the “French style” in epistemologyEpistemology, but he is also one of the first representatives of philosophy of biology in France. In the light of this double philosophical heritage, this chapter re-examines the relations between the works of Gayon, the tradition in which he first studied, and the one he later adopted, but not without reservations. Tracing his intellectual journey, this article explores why he naturally appears as a Canguilhemian, (...) a view against which he defends himself. Attending to the connexions that he established with the philosophers of biology will bring to light the growing tension that inhabits him, from the middle of the 1980s onwards, and which led him to identify some of the limits inherent to theHistorical epistemology matrix of historical epistemologyGayon, JeanOn historical epistemology, without disowning his first philosophical tradition. Finally, in an attempt to reconcile two approaches, I will underline the emergence in the thought of Jean Gayon of a third way seeking to overcome the opposition between a “unitarian” style that seeks to make a clear break with the history of scienceHistory of science and its philosophical past, and the “dualist” style which tends to stay above scientific debates, and which accepts a clear distinction between the work of science and the work of philosophy. Reuniting the history and the philosophy of the sciences, privileging the long durée and depths of history, where the problems of biology unfold, while also recognizing the value of analysing the conceptual puzzles which structure the contemporary life sciences, the oeuvre of Jean Gayon illustrates the complementary character of these disciplines.

In his ‘Theory of Light and Colours’, presented to the Royal Society in November 1801, Thomas Young defended a mechanical explanation of the coloured fringes observed outside of the shadow of an opaque object – the so-called ‘colours by inflection’ – that was based on the hypothesis of an ethereal density gradient surrounding all material bodies. However, two years later, he publicly rejected that hypothesis, without giving much detail of his reasons. Although Geoffrey Cantor has demonstrated the crucial role of (...) mechanical and astronomical arguments in explaining the withdrawal of this fundamental hypothesis long ago, the purpose of this article is to draw deeper attention to a set of experiments performed by David Brewster on the inflection of light, described in a letter he addressed to the Royal Society in January 1802, but was retained by William Herschel, and finally was neither read before the Society, nor published in its Philosophical Transactions. For the hypothesis that will be evaluated here is that these unpublished experiments of Brewster’s were eventually known to Young through the mediation of Herschel, and eventually played a significant role in Young’s rejection of his ether distribution hypothesis.

The present paper is a reading of Jean-Pierre Jeunet’s recent film, A Very Long Engagement, mainly through the lenses of Jacques Lacan’s psychoanalytical theory of the human subject—particularly his notion of the subject’s desire, which constitutes every human subject as a singular being. Moreover, for Lacan the subject faces the task of taking up his or her desire as a prerequisite for truly ethical action. The character of Mathilde in Jeunet’s film, it is argued, may be seen as being (...) paradigmatic in this respect, insofar as she acts in accordance with her desire. This is demonstrated with reference to the narrative structure of Jeunet’s film. (shrink)

Faced with the conflict between our intuition that no two things ever share a place at a time and these counterexamples to it, philosophers usually try to find a happy medium between sticking with the original intuition and rejecting all of its counterexamples or giving up the whole intuition and accepting all the counterexamples. Some counterexamples might be rejected on conceptual grounds : one may deny for instance that absolute space is in the same place that the entities located therein (...) on the ground that absolute space is not itself located. One may also reject the distinct existence of some of the entities put forward in the examples : determinable properties might be nothing else than boolean combinations of determinate ones, spots on a screen may be just four dimensional worms whose passing through each other is a matter of part sharing rather than compenetration, etc. But as long as the conceivability of at least one counterexample is granted, the impenetrability intuition has to be weake- ned. To this end, one can weaken either the modal force of the impenetrability intuition or its scope. One may claim for instance that things are impenetrable in our world, but grant that the remaining counterexample refers to genuine metaphysical possibilities (although not natural ones). On the other hand, on may claim that the impenetrability intuition does not bear on every entity in the outside world, but only on some of them. Locke, famously, did not want to give up the metaphysical necessity of impenetrability, but agreed to restrict it to entities of the same kind.4 One other way to restrict the scope of the intuition of impenetrability is to claim that only independent entities (substances, or things proper) are impenetrable , or that only material entities are.

The literature has long noted the ethical challenges related to auditors’ dual affiliations with both a profession and an organization that practices the profession. The notion of organizational/professional conflict, in particular, was introduced to capture the potential problems involved in this situation, such as when an auditor engages in behaviors aimed at pleasing the client rather than safeguarding the public interest. However, inconsistent findings leave open the debate about how auditors manage their dual affiliation and question the underlying mechanisms (...) by which auditors structure their identity and experience their work life. To advance understanding of this issue, this research investigates the relationships between auditors’ organizational identification, professional identification, and emotions at work, using a questionnaire survey of 126 French Big 4 auditors and a two-step split-sampling design. The results show that the two forms of identification have a different relationship with emotions: positive for organizational identification but ambivalent for professional identification. These findings contribute to our understanding of professionals’ work experiences in large organizations. (shrink)

This book analyzes emergency legislations formed in response to terrorism. In recognition that different countries, with different legal traditions, have different solutions, it adopts a comparative point of view. The countries profiled include America, France, Israel, Poland, Germany and United Kingdom. The goal is not to offer judgment on one response or the other. Rather, the contributors offer a comprehensive and thoughtful examination of the entire concept. In the process, they draw attention to the inadaptability of traditional legal and philosophical (...) categories in a new and changing political world. The contributors first criticize the idea of these legislations. They then go on to develop different models to respond to these crises. They build a general analytical framework by answering such questions as: What is an emergency legislation? What kinds of emergencies justify laws of this nature? Why is contemporary terrorism such a specific emergency justifying new laws? Using legal and philosophical reflections, this study looks at how we are changing society. Coverage also provides historical experiences of emergency legislations to further illustrate this point. In the end, readers will gain insight into the long-term consequences of these legislations and how they modify the very work of the rule of law. (shrink)

The identification of neural substrates underlying the long lasting debilitating impact of drug cues is critical for developing novel therapeutic tools. Metabolic coupling has long been considered a key mechanism through which astrocytes and neurons actively interact in response of neuronal activity, but recent findings suggested that disrupting metabolic coupling may represent an innovative approach to prevent memory formation, in particular drug‐related memories. Here, we review converging evidence illustrating how memory and addiction share neural circuitry and molecular mechanisms (...) implicating lactate‐mediated metabolic coupling between astrocytes and neurons. With several aspects of addiction depending on mnemonic processes elicited by drug experience, disrupting lactate transport involved in the formation of a pathological learning, linking the incentive, and motivational effects of drugs with drug‐conditioned stimuli represent a promising approach to encourage abstinence.

Alors que le débat sur le caractère scientifique ou pseudo-scientifique de l’agriculture biodynamique occupe régulièrement le débat public, l’histoire et la philosophie des sciences ne semblent que très peu s’être emparées de ce sujet. La thèse défendue ici est double : tout d’abord, si l’agriculture biodynamique rencontre un relatif succès aujourd’hui, cela tient sans doute au fait que son théoricien, R. Steiner, a été un des premiers à critiquer le paradigme qui domine l’agronomie, ou en tout cas l’agriculture, depuis plus (...) d’un siècle. Cette critique semble d’ailleurs se maintenir dans ses motifs tout au long du XXe siècle, jusqu’à une certaine critique contemporaine de l’agro-industrie et de ses conséquences désastreuses sur l’environnement. Or, et c’est la seconde thèse défendue ici, cette critique semble méconnaître voire occulter la réalité des débats internes qui ont traversé l’agronomie au cours du XXe siècle et qui continuent de l’agiter aujourd’hui : l’agronomie système a ainsi par exemple intégré dans ses objets des éléments de l’agriculture biodynamique. Selon nous, le problème principal est que l’agronomie est souvent abordée selon une approche externaliste, qui doit impérativement être complétée par une approche internaliste afin tout d’abord de distinguer ce qui relève de la science et ce qui relève du mysticisme, et ensuite de saisir toute la richesse historique et épistémologique de l’agronomie.

Publication de maisons de Lato, dégagées en 1970-1971.

À l'exception de la maison V, où fut mise au jour une baignoire, ainsi qu'un riche matériel céramique du milieu du IIe s. av. J.-C, les autres maisons étaient (...) vides lors de leur découverte ; il est donc difficile d'en préciser la datation dans le cadre de l'époque hellénistique.

L'ensemble évoque un paragraphe des Lois de Platon, qui prône l'incorporation des habitations particulières dans la fortification d'une ville. C'est en fait un rempart de ce genre que les habitants de Lato vont construire, avec la superbe porte Ouest. (shrink)

The aim of this study was to test the effect of face cooling with cold water vs. face cooling with neutral water during high-intensity swimming training on both the core temperature and thermal perceptions in internationally ranked long-distance swimmers during 2 randomized swimming sessions. After a standardized warm-up of 1,200 m, the athletes performed a standardized training session that consisted of 2,000 m at a best velocity then 600 m of aerobic work. Heart rate was continuously monitored during 5 (...) × 400 m, whereas Tco, thermal comfort, and thermal sensation were measured before and after each 400 m. Before and after each 400 m, the swimmers were asked to flow 200 mL of cold water or neutral water packaged in standardized bottles on their face. The swimmers were asked don’t drink during exercise. The velocity was significantly different between cold water and neutral water. The Tco was increased by ±0.5°C at race pace, under both face cooling conditions with no significant difference. No significant changes were noted in mean HR. TC was higher with Cold Cooling than Neutral Cooling and TS was lower with Cold cooling compared with Neutral cooling. The changes in perceptual parameters caused by face cooling with cold water reflect the psychological impact on the physical parameters. The mean velocity was less important with face cooling whereas the heat rate and Tco were the same in the both conditions. The mechanism leading to these results seems to involve brain integration of signals from physiological and psychological sources. (shrink)

In fact, his threefold division of church history in line with Christ's three advents, which is featured in his... (shrink)

I argue that by attending to a distinction among perspectives on the root causes of our reactive attitudes, we can better understand the bases and limitations of long-standing debates about free will and moral responsibility. I characterize this distinction as “objectivism vs. subjectivism.” I bring out this distinction by, first, scrutinizing an especially sharp divergence between Peter Strawson and Peter John Olivi: for Olivi, our ordinary human attitudes make it obvious that we have free will, and our attitudes would (...) be senseless if we did not firmly believe that we have free will; for Strawson, reactive attitudes would carry on despite a theoretical acceptance that we lack free will. I apply my distinction to more recent disagreements, such as between Peter van Inwagen and John Martin Fischer/Mark Ravizza. By getting clearer on why we disagree, we can move closer toward a resolution and we can avoid talking past each other. (shrink)

In this paper, I explore the connection between Olivi’s views about the nature of conscious experience, on the one hand, and his views about the nature of the soul on the other. In particular, I argue that Olivi’s account of the soul as essentially active and essentially reflexive entails a commitment on his part to a kind of innate self-knowing. I further show that, for Olivi, this primal psychological self-reflexivity plays an important role in explaining the subjective character of conscious (...) states. (shrink)

On August 19, 1297, a young man of royal heritage died in the household of the Count of Provence and King of Naples at Brignoles, a short distance from Marseille. The young man was Louis of Anjou, a Franciscan friar and Bishop of Toulouse, who had renounced his inheritance and claim to the Kingdom of Naples to pursue a religious vocation. Only twenty-three years old when he died, Louis nevertheless had long been inspired by Franciscan spirituality, and less than (...) eight months before had realized his dream of professing vows within the Order of Friars Minor at the same time that he submitted to consecration as Bishop of Toulouse. In March of the following year, Peter of John Olivi, a native son of .. (shrink)

Generic stereotypes are generically formulated generalizations that express a stereotype, like “Mexican immigrants are rapists” and “Muslims are terrorists.” Stereotypes like these are offensive and should not be asserted by anyone. Yet when someone does assert a sentence like this in a conversation, it is surprisingly difficult to successfully rebut it. The meaning of generic sentences is such that they can be true in several different ways. As a result, a speaker who is challenged after asserting a generic stereotype can (...) often simply dismiss the objection and maintain that the stereotype is true in a way that is compatible with the challenger’s objection. In this paper, a semantic theory for generics is presented that accounts for this type of defensive shifting in upholding generic stereotypes. This theory is then used to develop two strategies to object more efficiently. The first strategy is to immediately deny that either of the two possible ways in which a generic can be true obtains. The second strategy is to deny the satisfaction of an additional condition that is necessary for a generic sentence to be true. (shrink)

One primary goal for metaphysical theories of natural kinds is to account for their epistemic fruitfulness. According to cluster theories of natural kinds, this epistemic fruitfulness is grounded in the regular and stable co- occurrence of a broad set of properties. In this paper, I defend the view that such a cluster theory is insufficient to adequately account for the epistemic fruitfulness of kinds. I argue that cluster theories can indeed account for the projectibility of natural kinds, but not for (...) several other epistemic operations that natural kinds support. Natural kinds also play a role in scientific explanations and categorizations. A theory of natural kinds can only account for these additional kind-based epistemic practices if it also analyzes their causal structure. (shrink)

This chapter defends an axiological theory of pain according to which pains are bodily episodes that are bad in some way. Section 1 introduces two standard assumptions about pain that the axiological theory constitutively rejects: (i) that pains are essentially tied to consciousness and (ii) that pains are not essentially tied to badness. Section 2 presents the axiological theory by contrast to these and provides a preliminary defense of it. Section 3 introduces the paradox of pain and argues that since (...) the axiological theory takes the location of pain at face value, it needs to grapple with the privacy, self-intimacy and incorrigibility of pain. Sections 4, 5 and 6 explain how the axiological theory may deal with each of these. (shrink)

This paper defends a realist account of the composition of Newtonian forces, dubbed ‘residualism’. According to residualism, the resultant force acting on a body is identical to the component forces acting on it that do not prevent each other from bringing about its acceleration. Several reasons to favor residualism over alternative accounts of the composition of forces are advanced. (i) Residualism reconciles realism about component forces with realism about resultant forces while avoiding any threat of causal overdetermination. (ii) Residualism provides (...) a systematic semantics for the term ‘force’ within Newtonian mechanics. (iii) Residualism allows us to precisely apportion the causal responsibility of each component force in the ensuing acceleration. (iv) Residualism handles special cases such as null forces, single forces, and antagonistic forces in a natural way. (v) Residualism provides a neat picture of the causal powers of forces: each force essentially has two causal powers⎯the power to bring about accelerations (sometimes together with other co-directionnal forces) and the power to prevent other forces from doing so⎯exactly one of which is manifested at a time. (vi) Residualism avoids commitment to unobservable effects of forces: forces cause either stresses (tensile or compressive) or accelerations. (shrink)

The thesis defended, the “guise of the ought”, is that the formal objects of desires are norms (oughts to be or oughts to do) rather than values (as the “guise of the good” thesis has it). It is impossible, in virtue of the nature of desire, to desire something without it being presented as something that ought to be or that one ought to do. This view is defended by pointing to a key distinction between values and norms: positive and (...) negative norms (obligation and interdiction) are interdefinable through negation; positive and negative values aren’t. This contrast between the norms and values, it is argued, is mirrored, within the psychological realm, by the contrast between the desires and emotions. Positive and negative desires are interdefinable through negation, but positive and negative emotions aren’t. The overall, Meinongian picture suggested is that norms are to desires what values are to emotions. (shrink)

Can we maintain that purple seems composed of red and blue without giving up the impenetrability of the red and blue parts that compose it? Brentano thinks we can. Purple, according to him, is a chessboard of red and blue tiles which, although individually too small to be perceived, are together indistinctly perceived within the purple. After a presentation of Brentano’s solution, we raise two objections to it. First, Brentano’s solution commits him to unperceivable intentional objects (the chessboard’s tiles). Second, (...) his chessboard account fails in the end to explain the phenomenal spatial continuity of compound colours. We then sketch an alternative account, which, while holding fast to the phenomenal compoundedness of the purple and to the impenetrability of component colours, avoids introducing inaccessible intentional objects and compromising on the continuity of the purple. According to our proposal, instead of being indistinctly perceived spatial parts of the purple, red and blue are distinctly perceived non- spatial parts of it. (shrink)

I present and defend Reinach's theory of ownership according to which, prior to the positive law, one finds a distinction between possession, ownership and property rights. Ownership is not a bundle of positive rights, but a primitive natural relation that grounds the absolute right to behave as one wishes towards the thing one owns. In reply to some objections raised against it, I argue that Reinach's theory of property is morally and politically non-committal; and that it in fact has the (...) ressources for dealing with the vexing issue of the origin of ownership.
