Kaplan claims in Demonstratives that no operator may manipulate the context of evaluation of natural language indexicals. We show that this is not so. In fact, attitude reports always manipulate a context parameter (or, rather, a context variable). This is shown by (i) the existence of De Se readings of attitude reports in English (which Kaplan has no account for), and (ii) the existence of a variety of indexicals across languages whose point of evaluation can be shifted, but only in (...) attitude reports. We develop an alternative account within an extensional framework with overt quantification over times, worlds and contexts. Various typological facts are discussed, esp. the distinction between English, Amharic and Ewe pronouns, and that between English and Russian tenses. (shrink)

According to one productive and influential approach to cognition, categorization, object recognition, and higher level cognitive processes operate on a set of fixed features, which are the output of lower level perceptual processes. In many situations, however, it is the higher level cognitive process being executed that influences the lower level features that are created. Rather than viewing the repertoire of features as being fixed by low-level processes, we present a theory in which people create features to subserve the representation (...) and categorization of objects. Two types of category learning should be distinguished. Fixed space category learning occurs when new categorizations are representable with the available feature set. Flexible space category learning occurs when new categorizations cannot be represented with the features available. Whether fixed or flexible, learning depends on the featural contrasts and similarities between the new category to be represented and the individual's existing concepts. Fixed feature approaches face one of two problems with tasks that call for new features: If the fixed features are fairly high level and directly useful for categorization, then they will not be flexible enough to represent all objects that might be relevant for a new task. If the fixed features are small, subsymbolic fragments (such as pixels), then regularities at the level of the functional features required to accomplish categorizations will not be captured by these primitives. We present evidence of flexible perceptual changes arising from category learning and theoretical arguments for the importance of this flexibility. We describe conditions that promote feature creation and argue against interpreting them in terms of fixed features. Finally, we discuss the implications of functional features for object categorization, conceptual development, chunking, constructive induction, and formal models of dimensionality reduction. Key Words: concept learning; conceptual development; features; perceptual learning; stimulus encoding. (shrink)

This paper argues that besides mechanistic explanations, there is a kind of explanation that relies upon “topological” properties of systems in order to derive the explanandum as a consequence, and which does not consider mechanisms or causal processes. I first investigate topological explanations in the case of ecological research on the stability of ecosystems. Then I contrast them with mechanistic explanations, thereby distinguishing the kind of realization they involve from the realization relations entailed by mechanistic explanations, and explain how both (...) kinds of explanations may be articulated in practice. The second section, expanding on the case of ecological stability, considers the phenomenon of robustness at all levels of the biological hierarchy in order to show that topological explanations are indeed pervasive there. Reasons are suggested for this, in which “neutral network” explanations are singled out as a form of topological explanation that spans across many levels. Finally, I appeal to the distinction of explanatory regimes to cast light on a controversy in philosophy of biology, the issue of contingence in evolution, which is shown to essentially involve issues about realization.

Qu'attendre des chercheurs en sciences sociales? Qu'ils fassent tout bonnement leur métier ou qu'à partir de leurs analyses ils s'impliquent dans les problèmes qui relèvent de leur compétence ou même qu'à partir de leur position de chercheur ils prennent publiquement position sur les grandes questions du jour? Ces alternatives sont loin d'épuiser le champ des possibles, mais les énoncer invite à s'interroger sur les rapports qu'entretiennent les travaux de recherche en sciences sociales avec les pratiques sociales qu'elles étudient. Ces questions (...) n'étaient pas étrangères à Philippe Lucas - et c'est peu dire. Elles sont aussi à l'origine de ce livre. Président de l'université Lumière-Lyon II avant d'être nommé recteur de l'Académie de Bordeaux puis de l'Académie de Caen, Philippe Lucas fut aussi et d'abord un chercheur qui concevait son travail de recherche comme un engagement. Sa " sociologie impliquée " supposait la confrontation des points de vue et le débat non seulement après coup, une fois le travail terminé, mais avant tout dès les premières investigations et tout au long de la recherche. Quel meilleur hommage rendre à Philippe Lucas que de reprendre aujourd'hui ces questions qui furent les siennes? Il les avait posées à sa manière mais leur actualité nous frappe, leur importance aussi. Ceux qui ont contribué à cet ouvrage collectif ont tenté d'y répondre et d'abord de les reformuler en proposant tantôt leur témoignage tantôt leurs réflexions de chercheurs sur l'implication et l'engagement : leur propre implication et celle de leurs disciplines, leur propre engagement et celui de leurs disciplines.

When do children become aware of themselves as differentiated and unique entity in the world? When and how do they become self-aware? Based on some recent empirical evidence, 5 levels of self-awareness are presented and discussed as they chronologically unfold from the moment of birth to approximately 4-5 years of age. A natural history of children's developing self-awareness is proposed as well as a model of adult self-awareness that is informed by the dynamic of early development. Adult self-awareness is viewed (...) as the dynamic flux between basic levels of consciousness that develop chronologically early in life. (shrink)

The development of geometrical analysis in the 10th century was partly inspired by the reception of the works of Apollonius, which Arab mathematicians translated as early as the preceding century. Al-Qūhī contributed to this development by writing several collections of problems dealing with Apollonian themes and solved by the method of analysis; however, it seems that they do not all occupy the same place in his work. The author gives here the edition, translation, and mathematical commentary of a short work, (...) entitled The determination of two straight lines from a point along a known angle, which presents the particularity of providing problems as geometrical lemmas to other studies. Indeed, al-Qūhī uses two of these lemmas in more complex constructions which belong to his Treatise on the art of the astrolabe. In this same treatise on the astrolabe, as well as in his Treatise on the perfect compass, this scholar also uses as lemmas several problems solved in another of his works, entitled The generation of points on straight lines according to ratios of which the terms are surfaces. This work is unfortunately lost, and all that remains of it are the traces which subsist in other treatises in which it has been used. This study seems to be necessary if one wishes to understand the organization of the work of al-Qūhī, a mathematician of the first rank who was representative of his time. (shrink)

William Alston’s argument against the deontological conception of epistemic justification is a classic—and much debated—piece of contemporary epistemology. At the heart of Alston’s argument, however, lies a very simple mistake which, surprisingly, appears to have gone unnoticed in the vast literature now devoted to the argument. After having shown why some of the standard responses to Alston’s argument don’t work, we elucidate the mistake and offer a hypothesis as to why it has escaped attention.

A great mathematician and teacher, and a physicist and philosopher in his own right, bridges the gap between science and the humanities in this exposition of the philosophy of science. He traces the history of science from Aristotle to Einstein to illustrate philosophy's ongoing role in the scientific process. In this volume he explains modern technology's gradual erosion of the rapport between physical theories and philosophical systems, and offers suggestions for restoring the link between these related areas. This book is (...) suitable for undergraduate students and other readers. 1962 ed. Index. 36 figures. (shrink)

Conceptualist accounts of the representational content of perceptual experiences have it that a subject _S_ can experience no object, property, relation, etc., unless _S_ "i# possesses and "ii# exercises concepts for such object, property, or relation. Perceptual experiences, on such a view, represent the world in a way that is conceptual.

Following a long-standing philosophical tradition, impartiality is a distinctive and determining feature of moral judgments, especially in matters of distributive justice. This broad ethical tradition was revived in welfare economics by Vickrey, and above all, Harsanyi, under the form of the so-called Impartial Observer Theorem. The paper offers an analytical reconstruction of this argument and a step-wise philosophical critique of its premisses. It eventually provides a new formal version of the theorem based on subjective probability.

Philippe Stern, qui fut conservateur en chef du Musée Guimet à Paris, est surtout connu comme historien des arts de l'Inde et de l'Asie du Sud-Est. Il a sinon créé, du moins perfectionné la méthode qui consiste à suivre l'évolution, à travers la vie d'un art, de motifs spécialement choisis pour en découvrir la chronologie jusque-là inconnue. Il a fait de cette méthode un outil sûr qui a permis en particulier de redresser la chronologie erronée de l'art khmer, d'établir (...) la chronologie de l'art cham de l'Annam ancien, de préciser la chronologie des temples hypogées de l'Inde classique et celles des nombreuses fondations du dernier grand roi khmer, Jayavarman VII. Mais cet archéologue, cet historien, ce conservateur de Musée fut surtout un amant du beau, préoccupé par la nature et le rôle profond de l'expérience esthétique. Ainsi mûrit lentement à travers toute une existence une oeuvre dont Beauté-Clef (Peter Lang, 1989) est un premier volet et dont voici le second volet. (shrink)

Le thème de la guerre appartient plutôt au domaine de la philosophie politique, domaine qui n’est pas celui sur lequel Marcel Conche a le plus travaillé. Dans ses derniers ouvrages, ce thème est néanmoins très présent. Au moment où la Seconde Guerre mondiale éclate, il a dix-sept ans. C’est dans ce contexte qu’il a choisi de devenir philosophe. Il aurait pu entrer dans la Résistance, mais il avait toute une enfance à rattraper. Le paradoxe est que cette période sombre de (...) notre histoire correspond pour lui à celle de sa libération. Cependant, on ne peut pas être sur tous les fronts : la philosophie, la lutte contre l’occupant. Quand il revient sur cette époque de sa vie, Marcel Conche évoque aussi la figure de Jean Cavaillès. Deux points de vue sur la guerre, deux attitudes différentes. Deux démarches qui, néanmoins, doivent être comprises ensemble. Toute la difficulté est en effet de donner la priorité à la vie sans renoncer à la liberté. (shrink)

In Parts of Classes, David Lewis outlined a reduction of ZFC to a second order mereology. His conclusion takes on the following form in this reconstruction: ZFC is susceptible to parameterized interpretation in M plus, there is a stronglyinaccessible partition. The proof makes use of the fact that ordered pairs in M plus an infinite partition are susceptible to parameterized interpretation.".

Mirror self-experience is re-casted away from the cognitivist interpretation that has dominated discussions on the issue since the establishment of the mirror mark test. Ideas formulated by Merleau-Ponty on mirror self-experience point to the profoundly unsettling encounter with one’s specular double. These ideas, together with developmental evidence are re-visited to provide a new, psychologically and phenomenologically more valid account of mirror self-experience: an experience associated with deep wariness.

Popper's well-known demarcation criterion has often been understood to distinguish statements of empirical science according to their logical form. Implicit in this interpretation of Popper's philosophy is the belief that when the universe of discourse of the empirical scientist is infinite, empirical universal sentences are falsifiable but not verifiable, whereas the converse holds for existential sentences. A remarkable elaboration of this belief is to be found in Watkins's early work on the statements he calls “all-and-some,” such as: “For every metal (...) there is a melting point.” All-and-some statements are both universally and existentially quantified in that order. Watkins argued that AS should be regarded as both nonfalsifiable and nonverifiable, for they partake in the logical fate of both universal and existential statements. This claim is subject to the proviso that the bound variables are “uncircumscribed” ; i.e., that the universe of discourse is infinite. (shrink)

The 1992 incorporation of an article by referendum in the SwissConstitution mandating that the federal government issue regulations onthe use of genetic material that take into account the dignity ofnonhuman organism raises philosophical questions about how we shouldunderstand what is meant by ``the dignity of nonhuman animals,'' andabout what sort of moral demands arise from recognizing this dignitywith respect to their genetic engineering. The first step in determiningwhat is meant is to clarify the difference between dignity when appliedto humans and (...) when applied to nonhumans. Several conceptions of humandignity should be rejected in favor of a fourth conception: the rightnot to be degraded. This right implies that those who have it have thecognitive capacities that are prerequisite for self-respect. In the caseof nonhuman organisms that lack this capacity, respecting their dignityrequires the recognition that their inherent value, which is tied totheir abilities to pursue their own good, be respected. This value isnot absolute, as it is in the case of humans, so it does not prohibitbreeding manipulations that make organisms more useful to humans. But itdoes restrict morally how sentient animals can be used. In regard togenetic engineering, this conception requires that animals be allowedthe uninhibited development of species specific functions, a positionshared by Holland and Attfield, as opposed to the Original Purposeconception proposed by Fox and the Integrity of the Genetic Make-upposition proposed by Rolston. The inherent value conception of dignity,as here defended, is what is meant in the Swiss Constitution article. (shrink)

This study aims at justifying one of Gilbert Durand’s postulates according to which all imaginaire (as a result of mental imagery) is anchored in our physiology but by directing it rather now towards our neurophysiology. New advances in neurobiology, connectome and neurogenomics lead to rethinking the framework of psychic activity and the induction of neural images.

A partir d’une présentation de Sois mon corps, cet article se propose de mettre en lumière quelques prolongements contemporains de la dialectique hégélienne du maître et de l’esclave. Avec l’interprétation qu’en propose J. Butler notamment, c’est le statut du corps qui devient problématique dès lors que le désir de s’en détacher entre en tension avec une ontologie relationnelle et sociale de la vie corporelle qui signe la vulnérabilité de l’être vivant.

ABSTRACT Unless a democratic citizenry, when it gets shaped at school, is asked to formulate complex answers to simple questions, there is no other avenue for their destiny than ressentiment against “the world,” which expresses itself in either a parading of culture or an inordinate sense of revolt.

The relations between rationality and optimization have been widely discussed in the wake of Herbert Simon's work, with the common conclusion that the rationality concept does not imply the optimization principle. The paper is partly concerned with adding evidence for this view, but its main, more challenging objective is to question the converse implication from optimization to rationality, which is accepted even by bounded rationality theorists. We discuss three topics in succession: (1) rationally defensible cyclical choices, (2) the revealed preference (...) theory of optimization, and (3) the infinite regress of optimization. We conclude that (1) and (2) provide evidence only for the weak thesis that rationality does not imply optimization. But (3) is seen to deliver a significant argument for the strong thesis that optimization does not imply rationality. (shrink)

Straightening the current ‘value-laden turn’ (VLT) in the philosophical literature on values in science, and reviving the legacy of the value-free ideal of science (VFI), this paper argues that the influence of extra-scientific values should be minimised—not excluded—in the core phase of scientific inquiry where claims are accepted or rejected. Noting that the original arguments for the VFI (ensuring the truth of scientific knowledge, respecting the autonomy of science results users, preserving public trust in science) have not been satisfactorily addressed (...) by proponents of the VLT, it proposes four prerequisites which any model for values in the acceptance/rejection phase of scientific inquiry should respect, coming from the fundamental requirement to distinguish between facts and values: (1) the truth of scientific knowledge must be ensured; (2) the uncertainties associated with scientific claims must be stated clearly; (3) claims accepted into the scientific corpus must be distinguished from claims taken as a basis for action. An additional prerequisite of (4) simplicity and systematicity is desirable, if the model is to be applicable. Methodological documents from international institutions and regulation agencies are used to illustrate the prerequisites. A model combining Betz’s conception (stating uncertainties associated with scientific claims) and Hansson’s corpus model (ensuring the truth of the scientific corpus and distinguishing it from other claims taken as a basis for action) is proposed. Additional prerequisites are finally suggested for future research, stemming from the requirement for philosophy of science to self-reflect on its own values: (5) any model for values in science must be descriptively and normatively relevant; and (6) its consequences must be thoroughly assessed.

As is well known, the late Husserl warned against the dangers of reifying and objectifying the mathematical models that operate at the heart of our physical theories. Although Husserl’s worries were mainly directed at Galilean physics, the first aim of our paper is to show that many of his critical arguments are no less relevant today. By addressing the formalism and current interpretations of quantum theory, we illustrate how topics surrounding the mathematization of nature come to the fore naturally. Our (...) second aim is to consider the program of reconstructing quantum theory, a program that currently enjoys popularity in the field of quantum foundations. We will conclude by arguing that, seen from this vantage point, certain insights delivered by phenomenology and quantum theory regarding perspectivity are remarkably concordant. Our overall hope with this paper is to show that there is much room for mutual learning between phenomenology and modern physics. (shrink)

I will present and criticise the two theories of truthmaking David Armstrong offers us in Truth and Truthmakers (Armstrong 2004), show to what extent they are incompatible and identify troublemakers for both of them, a notorious – Factualism, the view that the world is a world of states of affairs – and a more recent one – the view that every predication is necessary. Factualism, combined with truthmaker necessitarianism – ‘truthmaking is necessitation’ – leads Armstrong to an all-embracing totality state (...) of affairs that necessitates not only everything that is the case but also everything else – that which is not the case, that which is merely possible or even impossible. All the things so dear to realists – rocks, natural properties, real persons – become mere abstractions from this ontological monster. The view that every predication is necessary does in some sense the opposite: it does away with totality states of affairs and, arguably, also with states of affairs. We have particulars and universals, partially identical and necessarily connected to everything else. Just by the existence of anything, everything is necessitated – the whole world mirrored in every monad. Faced with the choice between these two equally unappealing alternatives, I suggest returning to Armstrong’s more empiricist past: the world is not an all-inclusive One, nor necessitated by every single particular and every single universal, but a plurality of particulars and universals, interconnected by a contingent and internal relation of exemplification. While a close variant, truthmaker essentialism, can perhaps be saved, this means giving up on truthmaker necessitarianism. This, I think, what it takes to steer a clear empiricist course between the Scylla of Spinozist general factness and the Charybdis of a Leibnizian overdose of brute necessities. (shrink)

It was the general practice until not at all long ago to look at Turner as one of the moderns, if not as one of the founding fathers of modern art. He was a man straddling the fence between two periods, but he was looking forward. In a history of art that marches through time, forever endorsing what is about to be forgotten, wrapping up, as it were, one style to open eagerly the package of the next, such a position (...) is most enviable for, no matter where the times may be going, it is a hallmark of greatness to be ahead of one's time. There were things to be explained, of course, Turner himself, a keen pessimist, did not approved of the future and had little use for the present.1 His love of art was schooled on Reynolds' Discourses, and he remained loyal to them; his poets were Thomson and Pope and, among contemporaries, the rather frigid but delicate Samuel Rogers, a classicist par excellence. Above all, however, Turner looked back to classical antiquity for training and guidance, and for the delectation of his heart. And the poetry of the ancients, such as he could obtain it in translation, was as important to him as their art. What does one do with a declared classicist whom a historicizing hindsight feels compelled to rescue as a man of the future by making him a Romantic? It is a challenge stylistic analysis likes to meet, for it goes beneath what it declares to be the surface of a work of art to find its style, the essence that must conform to the presumed spirit of the age in question. The triumphant result of such studies in depth is a forgone conclusion as much as it is a surprise to the uninitiated. The facade of the Louvre, for example, used to suffice to make it a building in the classical style; it took the acumen of a Wölfflin to prove that it really was "baroque." The more the artist struggled not to be of his time, the more, poor man, he betrayed to the analyst that he was of his time. The Louvre facade stands convicted of being "classicizing-baroque."2 · 1. On Turner's view of the modern art of his time see John Gage, Color in Turner: Poetry and Truth , pp.97-105. On his literary education and taste see the seminal essay by Jerrold Ziff, "Turner on Poetry and Painting, " Studies in Romanticism 3 no. 4 : 193-215.

Developing tools is a crucial aspect of experimental practice, yet most discussions of scientific change traditionally emphasize theoretical over technological change. To elaborate on the role of tools in scientific change, I offer an account that shows how scientists use tools in exploratory experiments to form novel concepts. I apply this account to two cases in neuroscience and show how tool development and concept formation are often intertwined in episodes of tool-driven change. I support this view by proposing common normative (...) principles that specify when exploratory concept formation and tool development succeed to initiate scientific change. (shrink)

According to Conceptualists like John McDowell and Bill Brewer, the representational content of perceptual experiences is wholly conceptual. One of the main!and only!arguments they advance for this claim has to do with the epistemological role of perceptual experiences. I focus on Bill Brewers "1999# version of the argument. I show why Brewer fails to satisfactorily motivate the premises of his argument, and suggest that opponents of Conceptualism could accept these premises without thereby endorsing the conclusion. Finally, I consider whether the (...) conclusion really supports Conceptualism. (shrink)

Avec un titre comme Luther et la philosophie, depuis le xviiie siècle et dans les milieux « libéraux » du xixe siècle, on aurait pu s’attendre à un exposé, bien sûr complet, de la philosophie du Réformateur.
