This paper is devoted to Ibn Sinān's treatise on analysis and synthesis. Ibn Sinān's text deals with two distinct, though closely related, subjects. First he considers the classification of problems, founded on the logical criteria which are the number and degree of indetermination of the solutions and the number of hypotheses and their possible independence. This classification does not replace the Hellenistic one, which remains relevant insofar as it purports to solve geometrical problems, but complements it and has a different (...) frame of reference, applying principally to algebra, that new born science. Ibn Sinān's classification will be taken up and used by algebraists. Secondly, the text presents a new way of setting out analysis and synthesis, so that they become exactly reciprocal. This leads Ibn Sinān to bestow more importance on the role played by analysis in the course of the proof, the only role left to synthesis being to check that all implications involved in the course of analysis are in fact equivalences. This method will prove to be productive in algebra too, so much so that some algebraists will explicitly identify algebra with analysis. Cet article est consacré au traité d'lbn Sinān sur l'analyse et la synthèse; Ibn Sinān y aborde deux sujets distincts quoique étroitement liés: – une classification des problèmes, fondée sur les critères logiques que sont le nombre et le degré d'indetermination des solutions, ainsi que, mais de façon moins pertinente, le nombre des hypothèses et leur éventuelle indépendance. Cette classification ne se substitue pas à la classification hellénistique qui garde sa pertinence en matière de problèmes de géométrie, mais se développe à côté de celleci dans un cadre radicalement différent, et est directement applicable à l'algebre, science qui se crée aux X e et XI e siècles. La classification d'Ibn Sinān sera reprise et utilisée par les algébristes; – une nouvelle façon d'exposer l'analyse et la synthèse d'un problème, afin qu'elles deviennent exactement inverses l'une de l'autre, ce qui conduit Ibn Sinān à accorder dans ses démonstrations une importance accrue à l'analyse, le rôle de la synthèse n'etant plus que de vérifier que toutes les implications mises en œuvre dans l'analyse sont en fait des équivalences. C'est en algèbre également que cette méthode se montrera féconde, au point que certains algébristes n'hésiteront pas à identifier l'algèbre et l'analyse. (shrink)

In developing a theory of consciousness, one of the main problems has to do with determining what distinguishes conscious states from non-conscious ones—the delimitation problem. This paper explores the possibility of solving this problem in terms of self-awareness. That self-awareness is essential to understanding the nature of our conscious experience is perhaps the most widely discussed hypothesis in the study of consciousness throughout the history of philosophy. Its plausibility hinges on how the notion of self-awareness is unpacked. The idea that (...) consciousness involves self-awareness has been understood in two different ways: either as awareness of oneself—the subject of experience—or as awareness of the conscious episode itself. In this paper I argue (i) that every experience concerns the subject in a very specific way, involving what I will call ‘perspectival de se representation’, and (ii) that there is no need to appeal to the experience itself in order to characterize the awareness within that experience. The view I articulate explains the subjective nature of experience without over-intellectualizing it, accommodates the phenomenology of experience, and dispels any doubt about the need to find the self in introspection.

It is often claimed that a minimal form of self-awareness is constitutive of our conscious experience. Some have considered that such a claim is plausible for our ordinary experiences but false when considered unrestrictedly on the basis of the empirical evidence from altered states. In this paper I want to reject such a reasoning. This requires, first, a proper understanding of a minimal form of self-awareness – one that makes it plausible that minimal self-awareness is part of our ordinary experiences. (...) I will argue that it should be understood as Perspectival First-Person Awareness : a non-conceptual identification-free self-attribution that defines the first-person perspective for our conscious experience. I will offer a detailed characterization of PFP-Awareness in semantic and epistemological terms. With this tool in hand, I will review the empirical literature on altered states. I will focus on psychedelics, meditation and dreams, as they have been claimed to present the clearest cases in favor of a radical disruption of self-awareness. I will show that the rejection of the idea that minimal self-awareness is constitutive of our experience on the basis of this evidence is unfounded, for two main reasons. First, although there are good grounds to think that some forms of self-awareness that typically accompany our ordinary experiences are compromised, they do not support the claim that PFP-Awareness is absent. Secondly, the reports that could make us think of a radical disruption of self-awareness are most probably due to a confirmation bias – and hence we should mistrust them – derived from the expectations and metaphysical views of their subjects.

How computer games can be designed to create ethically relevant experiences for players. Today's blockbuster video games—and their never-ending sequels, sagas, and reboots—provide plenty of excitement in high-resolution but for the most part fail to engage a player's moral imagination. In Beyond Choices, Miguel Sicart calls for a new generation of video and computer games that are ethically relevant by design. In the 1970s, mainstream films—including The Godfather, Apocalypse Now, Raging Bull, and Taxi Driver—filled theaters but also treated their (...) audiences as thinking beings. Why can't mainstream video games have the same moral and aesthetic impact? Sicart argues that it is time for games to claim their place in the cultural landscape as vehicles for ethical reflection. Sicart looks at games in many manifestations: toys, analog games, computer and video games, interactive fictions, commercial entertainments, and independent releases. Drawing on philosophy, design theory, literary studies, aesthetics, and interviews with game developers, Sicart provides a systematic account of how games can be designed to challenge and enrich our moral lives. After discussing such topics as definition of ethical gameplay and the structure of the game as a designed object, Sicart offers a theory of the design of ethical game play. He also analyzes the ethical aspects of game play in a number of current games, including Spec Ops: The Line, Beautiful Escape: Dungeoneer, Fallout New Vegas, and Anna Anthropy's Dys4Ia. Games are designed to evoke specific emotions; games that engage players ethically, Sicart argues, enable us to explore and express our values through play. (shrink)

Suscités par la reprise massive de la recherche en astronomie au IXe siècle dans le monde islamique et essentiellement à Bagdad, laquelle nécessite des outils mathématiques nouveaux, une floraison de traités, tant astronomiques que mathématiques, voit le jour à cette époque. D'entre les traités mathématiques, un certain nombre est consacré à la ‘‘figure secteur”, c’est-à-dire au théorème dit ‘‘de Ménélaüs” sur la sphère, lequel généralise le théorème dit ‘‘de Ménélaüs” dans le plan. Ce théorème de Ménélaüs sur la sphère, ou (...) règle des six quantités, est, en l’absence du théorème des sinus sur la sphère, lequel ne date que de la deuxième moitié du Xe siècle, le principal outil de l'astronomie sphérique. Le traité de Thābit ibn Qurra sur La figure secteur est le premier de ces traités consacrés au théorème de Ménélaüs, tant dans le plan que sur la sphère, à nous être parvenu; point de départ de tout un courant, il influencera profondément le développement ultérieur de la géométrie sphérique. Ce traité, qui est en fait une épître adressée à un correspondant malheureusement anonyme, présente en outre l'intérêt de montrer que, dans le milieu scientifique de cette époque à Bagdad, beaucoup s'intéressaient à ce théorème, essayaient d'en énoncer d'autres cas de figure et de compléter la démonstration qu'en donne Ptolémée dans l'Almageste.

Once Apollonius' Conics had been translated from Greek into Arabic, they became a main reference and the principal tool in studying solid problems, algebraic equations of 3rd and 4th degrees, infinitesimal mathematics, etc. Mathematicians of the 9th–10th centuries also studied the conic sections' constructions, as well as their continuous drawing and their drawing by points. Ibrāhīm ibn Sinān, as his grandfather Thābit ibn Qurra, was one of the most active and inventive mathematicians in these fields. Late Hélène Bellosta examined (...) in this article Ibn Sinān's contribution.Une fois les Coniques d'Apollonius traduits en arabe, ces livres sont devenus la référence indispensable et le principal instrument dans l'étude des problèmes solides, des équations algébriques des 3e et 4e degrés, des problèmes des mathématiques infinitésimales, etc. Les mathématiciens des ixe-xe siècles ont également étudié les constructions des sections coniques ainsi que leur tracé par points et leur tracé continu.

We examine conceptual and methodological problems that arise in the course of the scientific study of possible influences of religious belief on the experience of physical pain. We start by attempting to identify a notion of religious belief that might enter into interesting psychological generalizations involving both religious belief and pain. We argue that it may be useful to think of religious belief as a complex dispositional property that relates believers to a sufficiently thick belief system that encompasses both cognitive (...) and non-cognitive elements. Such a conception of religious belief is more likely to correlate with psychological properties of believers that are both sufficiently shared and sufficiently unique to distinguish their psychology from believers in another religion or from non-believers. If the dispositional psychological property that constitutes religious belief does influence pain, then our analysis suggests that it doesn’t do so directly but rather through one of its occurrent manifestations. We offer a taxonomy of the different ways in which occurrent states of belief or experience may interact with physical pain, and we try to identify those that are more interesting or promising. We then proceed to employ the conceptual framework we developed to some of the existing evidence about the neural and psychological correlates of religious belief and experience, and about the cognitive modulation of physical pain. Finally we turn to analyse two experiments that directly investigated the relation between religious belief and pain. We draw attention to the limitations of existing evidence and end by suggesting directions for future conceptual and empirical inquiry. (shrink)

Written by pioneers in the field, this practical book presents an authoritative yet accessible overview of the methods and applications of causal inference. The text provides a thorough introduction to the basics of the theory for non-time-varying treatments and the generalization to complex longitudinal data.

Neglected diseases are severe conditions that mainly affect the world's poorest people. Those suffering from neglected diseases are mostly suffering from tropical infections that have failed to receive priority in pharmaceutical research and development programs, as well as in public health policies aimed at improving availability and access to preventive, diagnostic and curative medicine. The World Health Organization has issued a number of documents directing attention to the plight affecting one third of the world's population, assisted by active support from (...) private organizations, notably the Bill and Melissa Gates Foundation, but the overall situation remains dismal. In the wake of major socioeconomic processes including globalization, steadily growing economic disparity, healthcare inequality, the instability created by rogue states and terrorism, as well as massive migration, and epidemic outbreaks, the features of neglected diseases have been changing. Neglected populations affected by tropical diseases are suffering increasingly from non-infectious degenerative conditions and disabilities due to untreated chronic maladies. Pockets of poverty and neglect can also be detected in high-income countries, contributing to the emergence of new diseases and the reemergence of infections believed to be disappearing such as tuberculosis and the measles. Included in the issues of neglect are rare diseases, mostly of genetic origin, affecting a small number of patients that suffer from multiple life-shortening functional impairment and organ defects. Effective medicines are extremely expensive, allegedly because research and development of appropriate drugs is resources and time consuming, requiring exorbitant prices to recoup investment from a small number of consumers. Bioethics has been tardy in addressing the suffering and destitution of neglected and rare diseases. Convinced that permanently repeated denunciations blunt the sensitivity towards suffering, whereas statistics are bloodless and unable to elicit commitment, this book attempts to explore a different strategy. In an upstream approach, bioethics needs to engage in ethnographic fieldwork that confronts and shares the context in which people suffer, vividly presenting what epidemiological research has blunted into statistical data. Additionally, a downstream approach is suggested, requiring bioethics to vigorously and openly denounce unethical biomedical and pharmaceutical research, misdeeds in registration and marketing of drugs, and misalignment of policies with the unmet healthcare needs of the destitute. More than being critical observers, bioethicists ought to shed lurking conflicts of interests and seek active participation in planning research and public healthcare practices aimed at improving the lives of medically neglected populations.

Despite the emergence of computer games as a dominant cultural industry, we know little or nothing about the ethics of computer games. Considerations of the morality of computer games seldom go beyond intermittent portrayals of them in the mass media as training devices for teenage serial killers. In this first scholarly exploration of the subject, Miguel Sicart addresses broader issues about the ethics of games, the ethics of playing the games, and the ethical responsibilities of game designers. He argues (...) that computer games are ethical objects, that computer game players are ethical agents, and that the ethics of computer games should be seen as a complex network of responsibilities and moral duties. Players should not be considered passive amoral creatures; they reflect, relate, and create with ethical minds. The games they play are ethical systems, with rules that create gameworlds with values at play. Drawing on concepts from philosophy and game studies, Sicart proposes a framework for analyzing the ethics of computer games as both designed objects and player experiences. After presenting his core theoretical arguments and offering a general theory for understanding computer game ethics, Sicart offers case studies examining single-player games, multiplayer games, and online gameworlds from an ethical perspective. He explores issues raised by unethical content in computer games and its possible effect on players and offers a synthesis of design theory and ethics that could be used as both analytical tool and inspiration in the creation of ethical gameplay.

Socially responsible mutual funds match financial and environmental, social, and governance criteria in their portfolio management strategies. Several studies have examined the behavior of these funds in terms of return–risk, obtaining very different results. The present study discusses previous results and shows how these funds often outperform their conventional counterparts. Rather than the SR character of a mutual fund, a relevant explanation for this behavior is the cultural environment in which the fund operates. Thus, the ethical framework or corporate social (...) responsibility used by the fund and its management must be assessed by considering the cultural context of the fund. This notion is the main contribution of this paper. (shrink)
