Dans son exposé sur la hiérarchie des êtres supérieurs, Jamblique introduit l’étonnante mention d’un « rang angélique ». Il s’agit non du rang des anges eux-mêmes, mais de celui des âmes établies au rang des anges. Selon Jamblique, il peut arriver que les âmes, par la volonté divine, quittent leur rang et s’élèvent dans la hiérarchie, dans un processus et un mouvement inverses de ceux de l’incarnation où l’âme a le libre choix et descend dans la matière. Il apparaît que (...) l’âme angélique n’est pourtant pas désincarnée : elle est l’âme pure du théurge. Proclus en donne une illustration en avançant une interprétation du mythe d’Er où, de simple messager chez Platon, Er s’élève au rang des anges, interprétation qu’il cautionne par les pratiques théurgiques qui deviennent par là même le symbole en acte du mythe. Aussi la pratique théurgique vient-elle valider le discours platonicien et vice versa. (shrink)

Cet article traite des catalogues des peuples perçus et représentés comme sages dans le monde grec, depuis leur genèse durant la période hellénistique jusqu’à leurexploitationpar les chrétiens. Attentive à leurs dimensions chronologique, généalogique et topologique, cette étude se focalise sur les fonctions de ces catalogues. Elle met ainsi en exergue leur rôle dans les représentations de la transmission des savoirs ainsi que dans les débats interculturels et interreligieux des premiers siècles de notre ère.The Wise Peoples’ Catalogues: Functions and Contexts of (...) Use. This article deals with catalogues of peoples that are perceived and represented as wise in the Greek world, from their construction in the Hellenistic period until their exploitation by the Christians. By analysing their chronological, genealogical and topological dimensions, this paper focuses on the functions of these catalogues: it emphasises the role they played in the representations of the knowledge transmission process as well as in interreligious and intercultural debates in the Greco-Roman period.

The aim of this paper is to provide an account of how hunger motivates us to seek food and eat. It seems that the way that it feels to be hungry must play some role in it fulfilling this function. We propose that hunger is best viewed as a complex state involving both affective and somatic constituents, as well as, crucially, changes in the way in which the hungry agent’s attention is deployed. We argue that in order to capture the (...) distinctive way in which hunger motivates we need to articulate the relations amongst such components. The resulting account explains how hunger as an aversive affective reaction to a state of need motivates us specifically to eat and not to just to rid ourselves of the unpleasant sensations associated to it. We suggest, however, that there is more than this to the overall affective experience of the hungry agent, because hunger ordinarily facilitates the elicitation of other, positive affective reactions such as interest and appetite, and recruits them to further its function.

__Neurotechnology and Direct Brain Communication__ focuses on recent neuroscientific investigations of infant brains and of patients with disorders of consciousness, both of which are at the forefront of contemporary neuroscience. The prospective use of neurotechnology to access mental states in these subjects, including neuroimaging, brain simulation and brain computer interfaces, offers new opportunities for clinicians and researchers, but has also received specific attention from philosophical, scientific, ethical and legal points of view. This book offers the first systematic assessment of these (...) issues, investigating the tools neurotechnology offers to care for verbally non-communicative subjects and suggesting a multidisciplinary approach to the ethical and legal implications of ordinary and experimental practices. The book is divided into three parts: the first and second focus on the scientific and clinical implications of neurological tools for DOC patient and infant care. With reference to these developments, the third and final part presents the case for re-evaluating classical ethical and legal concepts, such as authority, informed consent and privacy. Neurotechnology and Direct Brain Communication will appeal to researchers and postgraduate students in the fields of cognitive science, medical ethics, medical technology, and the philosophy of the mind. With implications for patient care, it will also be a useful resource for clinicians, medical centres and health practitioners. (shrink)

For the past two decades, Einstein's Hole Argument (which deals with the apparent indeterminateness of general relativity due to the general covariance of the field equations) and its resolution in terms of "Leibniz equivalence" (the statement that pseudo-Riemannian geometries related by active diffeomorphisms represent the same physical solution) have been the starting point for a lively philosophical debate on the objectivity of the point-events of space-time. It seems that Leibniz equivalence makes it impossible to consider the points of the space-time (...) manifold as physically individuated without recourse to dynamical individuating fields. Various authors have posited that the metric field itself can be used in this way , but nobody so far has considered the problem of explicitly distilling the "metrical fingerprint" of point-events from the gauge-dependent elements of the metric field. Working in the Hamiltonian formulation of general relativity, and building on the results of Lusanna and Pauri (2002), we show how Bergmann and Komar's "intrinsic pseudo-coordinates" (based on the value of curvature invariants) can be used to provide a physical individuation of point-events in terms of the true degrees of freedom (the "Dirac observables") of the gravitational field, and we suggest how this conceptual individuation could in principle be implemented with a well-defined empirical procedure. We argue from these results that point-events retain a significant kind of physical objectivity. (shrink)

We argue that in extensive decision problems (extensive games with a single player) with imperfect recall care must be taken in interpreting information sets and strategies. Alternative interpretations allow for different kinds of analysis. We address the following issues: 1. randomization at information sets; 2. consistent beliefs; 3. time consistency of optimal plans; 4. the multiselves approach to decision making. We illustrate our discussion through an example that we call the ‘‘paradox of the absentminded driver.’’ Journal of Economic Literature Classification (...) Numbers: C7, D0. 1997 Academic Press.

In this paper we argue that transparency of machine learning algorithms, just as explanation, can be defined at different levels of abstraction. We criticize recent attempts to identify the explanation of black box algorithms with making their decisions (post-hoc) interpretable, focusing our discussion on counterfactual explanations. These approaches to explanation simplify the real nature of the black boxes and risk misleading the public about the normative features of a model. We propose a new form of algorithmic transparency, that consists in (...) explaining algorithms as an intentional product, that serves a particular goal, or multiple goals (Daniel Dennet’s design stance) in a given domain of applicability, and that provides a measure of the extent to which such a goal is achieved, and evidence about the way that measure has been reached. We call such idea of algorithmic transparency “design publicity.” We argue that design publicity can be more easily linked with the justification of the use and of the design of the algorithm, and of each individual decision following from it. In comparison to post-hoc explanations of individual algorithmic decisions, design publicity meets a different demand (the demand for impersonal justification) of the explainee. Finally, we argue that when models that pursue justifiable goals (which may include fairness as avoidance of bias towards specific groups) to a justifiable degree are used consistently, the resulting decisions are all justified even if some of them are (unavoidably) based on incorrect predictions. For this argument, we rely on John Rawls’s idea of procedural justice applied to algorithms conceived as institutions. (shrink)

In the past decade the central principles of western feminist theory have been dramatically challenged. many feminists have endorsed post-structuralism's rejection of essentialist theoretical categories, and have added a powerful gender dimension to contemporary critiques of modernity. Earlier 'women' have been radically undermined, and newer concerns with 'difference', 'identity', and 'power' have emerged. Destabilizing Theory explores these developments in a set of specially commissioned essays by feminist theorists. Does this change amount to a real shift within feminist theory, or will (...) feminism's links with an emancipatory modernism reinstate an older political agenda? Can we transcend the common counterposition of equality and difference, or is feminism condemned to argue within the terms of this binary opposition? (shrink)

Even before Nietzsche, Stirner opened a crak inside the metaphysical western tradition, that always considered life as something that must be judged, understood and evaluated, and that used knowledge as the instrument to go deep in the truth of being. In The Ego and His Own we attend the attempt to reverse this tradition: thinking does not have the function to conceive and found what is «real», but it does make tough and assure the loss of concerns. The unbelief and (...) the loss of concerns are the elements of Stirner’s spectrology that, instead of imposing the laws of real life, it begins to fight «new battles» against the huge and horrible shadow of God. One of these battles, the one Stirner hard devote himself to, is the «Man’s death».

Un large public apprécie en Gaston Bachelard le philosophe de la rêverie poétique et l'épistémologue. Ses oeuvres consacrées à la question du temps sont moins connues. Cet ouvrage se propose de montrer en quoi les données actuelles des neurosciences apportent un éclairage nouveau à cette réflexion. Nombre d'hypothèses formulées en neurobiologie et en neuroesthétique renforce la thèse bachelardienne de la discontinuité du temps vécu et la conception qu'avait le philosophe de "l'instant poétique".

The pluralist sheds the more traditional ideas of truth and ontology. This is dangerous, because it threatens instability of the theory. To lend stability to his philosophy, the pluralist trades truth and ontology for rigour and other ‘fixtures’. Fixtures are the steady goal posts. They are the parts of a theory that stay fixed across a pair of theories, and allow us to make translations and comparisons. They can ultimately be moved, but we tend to keep them fixed temporarily. Apart (...) from considering rigour of proof as a fixture, I discuss fixed models, invariant notions and fixed information about objects across theories. There are other fixtures, but it is enough to start with these. (shrink)

Most scientific theories are globally inconsistent. Chunk and Permeate is a method of rational reconstruction that can be used to separate, and identify, locally consistent chunks of reasoning or explanation. This then allows us to justify reasoning in a globally inconsistent theory. We extend chunk and permeate by adding a visually transparent way of guiding the individuation of chunks and deciding on what information permeates from one chunk to the next. The visual representation is in the form of bundle diagrams. (...) We then extend the bundle diagrams to include not only reasoning in the presence of inconsistent information or reasoning in the logical sense of deriving a conclusion from premises, but more generally reasoning in the sense of trying to understand a phenomenon in science. This extends the use of the bundle diagrams in terms of the base space and the fibres. We then apply this to a case in physics, that of understanding binding energies in the nucleus of an atom using together inconsistent models: the liquid drop model and the shell model. We draw some philosophical conclusions concerning scientific reasoning, paraconsistent reasoning, the role of logic in science and the unity of science. (shrink)

There are three elements in this paper. One is what we shall call ‘the Hungarian project’. This is the collected work of Andréka, Madarász, Németi, Székely and others. The second is Molinini’s philosophical work on the nature of mathematical explanations in science. The third is my pluralist approach to mathematics. The theses of this paper are that the Hungarian project gives genuine mathematical explanations for physical phenomena. A pluralist account of mathematical explanation can help us with appreciating the significance of (...) the Hungarian project. The significance consists in the fruitfulness and spread of the project. The spread is wide because the explanations are written in the very familiar language of first-order logic with identity. For this reason, the explanation is understandable to many mathematicians. Because of the methodology adopted in the Hungarian project, the explanations are fruitful in another sense. In the Hungarian project certain questions are asked that would not be asked with a more usual methodology. The Hungarians are distinguished from other scientists in asking logical and mathematical questions, and these both deepen our understanding of the physical theories and induce further spread to mathematics and philosophy.

Long considered as an economic giant and a political dwarf, Japan begins to solve this paradox by acquiring a political weight on the international scene. lts diplomacy remains non-assertive and its military role limited. But it has an increasing influence on the structure of the world economy by the size of its GNP, the composition and spread of its external economy and its capital ftows, and by the impact of its industrial policy on the international division of labour. The growing (...) macroeconomic and financial interdependence between the US and Japan has an incidence on defence high technology and on the transfert of resources to the Third World. Japan's new status as a world power is acknowledged even by Gorbachov's « Eastern » policy. Japan's case weakens the assumption of the realist paradigm of international relations theory that power and interdependence are incompatible. (shrink)

Ethical reflection on Artificial Intelligence (AI) has become a priority. In this article, we propose a methodological model for a comprehensive ethical analysis of some uses of AI, notably as a replacement of human actors in specific activities. We emphasize the need for conceptual clarification of relevant key terms (e.g., intelligence) in order to undertake such reflection. Against that background, we distinguish two levels of ethical analysis, one practical and one theoretical. Focusing on the state of AI at present, we (...) suggest that regardless of the presence of intelligence, the lack of morally relevant features calls for caution when considering the role of AI in some specific human activities.

Most guidelines and proposalsfor Internet research ethics are based onregulations for human subjects research. In therelated research, Internet material is viewedas animate and described as people. Humanitiesresearchers have rarely been a part of thedebate about Internet research ethics and thepractices of these scholars have not been takeninto consideration when drafting most of theguidelines. This threatens to limit the kindsof Internet research that can be performed – critical strategies are particularlydiscouraged – and the ways that researchers andother users understand the Internet.Researchers (...) who use human subjects models havenot fully acknowledged computer mediation, theconstructed aspects of Internetrepresentations, and the screen. If we viewInternet material as cultural production thenthe models for Internet research would be ArtHistory and Visual Culture, English andLiterary Studies, Film and Media Studies, Musicand Sound Studies, and Theatre and PerformanceStudies. A more complete integration of theseapproaches into Internet Studies – either as asole investigatory strategy or in tandem withother forms of inquiry – would changeresearchers' ethical questions. It would alsoshow instances in which human subjectsguidelines do not apply to complex Internetmaterial. It is imperative to demonstrate thatInternet material is not people because thisconception makes highly constructed words andimages seem natural and stereotypedrepresentations appear to be real.

Prenatal screening can significantly benefit parents and the community. However, it has created a dilemma for women as it requires them to quickly decide whether to continue a pregnancy or terminate it should the test indicate a foetal abnormality. This can be psychologically traumatic for women torn between their connection to an unborn child with all its possible imperfections, and a desire to prevent its suffering as a disabled child in later life. A woman must also consider her own and (...) her family's future welfare. Extensive research into the physical aspects of prenatal screening has not explored the meaning of the experience for women or whether termination is the most appropriate option. This article examines recent qualitative studies, concluding that women who terminate a pregnancy following prenatal screening may experience an acute grief reaction or be plagued by guilt and fear that can precipitate marital breakdown. Additionally, there is a risk that through striving to eradicate congenital disability, a community risks promoting a cult of perfectionism that may have discriminatory effects on disabled people.
