Sociality may not be a defining feature of social learning. Complex social systems have been predicted to favour the evolution of social learning, but the evidence for this relationship is weak. In birds, only one study supports the hypothesis that social learning is an adaptive specialisation to social living. In nonhuman primates, social group size and social learning frequency are not correlated. Though cetaceans may prove an exception, they provide a useful group with which to test these ideas.

The ratio bias—according to which individuals prefer to bet on probabilities expressed as a ratio of large numbers to normatively equivalent or superior probabilities expressed as a ratio of small numbers—has recently gained momentum, with researchers especially in health economics emphasizing the policy importance of the phenomenon. Although the bias has been replicated several times, some doubts remain about its economic significance. Our two experiments show that the bias disappears once order effects are excluded, and once salient and dominant incentives (...) are provided. This holds true for both choice and valuation tasks. Also, adding context to the decision problem does not alter this finding. No ratio bias could be found in between-subject tests either, which leads us to the conclusion that the policy relevance of the phenomenon is doubtful at best. (shrink)

Performance-contingent compensation by means of stock options may induce risk-taking in agents that is excessive from the point of view of the company or the shareholders. We test whether increasing shareholder control may be an effective checking mechanism to rein in such excessive risk-taking. We thus tell one group of experimental CEOs that they may have to justify their decision-making processes in front of their shareholders. This indeed reduces risk-taking and increases the performance of the companies they manage. Implications are (...) discussed. (shrink)

PurposeIn Western society, the measurement of weight is prioritized over a person’s bodily experience. Hermeneutic philosopher Gadamer warned against the emphasis on measurement, rather than experience, in the medical sciences. An examination of the complexity of the experience of weight provides the opportunity to shift focus from quantifying the connection between health and weight to the experience of the person being weighed.MethodsThis qualitative hermeneutic study aims to understand people’s experiences of weight from the interviews of professionals and lay experts. Interviews (...) were analyzed using an interpretive hermeneutic method.ResultsThe interviews revealed that weight was experienced as a number imbued with meaning and bias, as a number that could be manipulated, and as a constant and anticipated bodily change. Weight change was expected and often unwelcomed, despite weight being a quality of the body that is always in flux. External measures of weight meant to monitor wellness and health inadvertently became an unhealthy fixation that prevented some participants from fully participating in life events and appreciating the stages their bodies were in.ConclusionWeight change is a necessary condition of being human, and bodies are and will be constantly changing. To achieve health and harmony, one must fit together the acceptance of change and their bodily experience of weight. It is often the preoccupation with weight, not weight itself, that gets in the way of living. (shrink)

It would be contradictory to ask phainesthai to support both the strict sense (M. Schofield, M. Nussbaum), and metaphorical use (Simplicius) of phantasia. De anima, 428a2, raises many issues. When discovering imagination, Aristotle himself seems to use the word phantasia metaphorically.

At its core, the evolution of democratic civil society is a process of transcending existing, historical social space, a process that desires to dissolve "political society" into "civil society" and with it to reformulate space as more democratic, participatory public space, and global spheres of interaction. In this article, the author examines the implications of globalization and the evolution of democratic civil society. Drawing on the work of French theorists de Certeau and Lefebvre, the author examines the nature of (...) space as a social construct and the importance of understanding space as a practiced place in relation to the evolution of democratic civil society that makes transnational space a practiced place for global civil society. The author argues that as globalization spreads across nation-states, spatial forces produced by economic, cultural, and political discourses and practices give way to the potential for the evolution of democratic civil society.

Fragments d'un manuscrit de Ménandre découverts et publiés par M. Gustave Lefebvre, Inspecteur en chef des antiquités de l'Égypte. Le Caire. 1907. Pp. xix + 221. £1.

Le concept d’Allemagne permet de révéler, selon une approche« misologique », l’ampleur des désaccords ayant présidé à la définition du concept d’État en France. De ce dernier, l’on aborde divers emplois qu’illustrent des modèles d’État. Le « modèle germanique » opère ainsi dans un débat qui est le creuset de la connaissance politique moderne, avec ses apories: celles de la souveraineté externe, de l’ordre interétatique, de la confédération. L’article expose alors la relation entre les théories du droit public et la (...) « continuité des assemblées »; d’une certaine manière, le fondement de l’ordre politique. Au final, le droit public apparaît comme le transfert du pouvoir temporel à l’instituant, au collectif, et son affaiblissement, comme la raison d’être de l’étatisme. (shrink)

In this introduction, I briefly summarize Sophia Moreau's Faces of Inequality. I situate her monograph within two highly contemporary bodies of literature — relational egalitarianism and discrimination theory — to show how it provides important insights for understanding both what it means to treat others as equals in society and how to define wrongful discrimination. Moreau's work on discrimination is of great relevance for philosophers and socio-legal theorists alike as the commentaries from the symposium contributors demonstrate, including Dale Smith, Pablo (...) Gilabert, Andrea Sangiovanni, Daniel Viehoff, Jessica Eisen, Alysia Blackham, and Iyiola Solanke. (shrink)

The status of indirect discrimination is ambiguous in the current literature. This paper addresses two contemporary and related debates. First, for some, indirect discrimination is not truly a distinct kind of discrimination, but it is simply a legal construct designed to address distributive inequalities between groups. Second, even if one accepts that indirect discrimination is a distinct type of discrimination, the connection between the two kinds of discrimination, direct and indirect, is debated. For some, they are distinct act-types, while for (...) others, indirect discrimination should be conceived as a side effect of prior cases of direct discrimination. In this paper, I argue that indirect discrimination is a distinct act-type that can take place without being connected to prior instances of direct discrimination. (shrink)

Sextus Empiricus (IIe-IIIe s. ap. J.-C.) est le dernier philosophe sceptique de l'Antiquite et le seul dont l'uvre soit en grande partie conservee. Son Contre les dogmatiques prend pour cible la connaissance philosophique. Cet ensemble de traites tres argumente est articule suivant la distinction, d'epoque hellenistique, entre trois parties de la philosophie, la logique, la physique et l'ethique. On donne ici la premiere traduction francaise de la premiere et plus importante partie de cet ouvrage, le Contre les logiciens, qui conteste (...) la possibilite meme de connaitre. Prenant appui sur la distinction entre " choses apparentes " et " choses cachees ", Sextus Empiricus traite en premier lieu du " critere de la verite " ou des voies d'acces a la connaissance des choses apparentes. Un long developpement doxographique qui conduit des philosophes presocratiques aux Stoiciens, aux Epicuriens et aux Academiciens precede l'expose des arguments qui plaident en faveur de l'inexistence d'un tel critere. Au livre II, Sextus Empiricus met en question, a propos des choses cachees, le " vrai " lui-meme, avant de faire ressortir la faiblesse de l'inference semiotique et celle de la demonstration. L'ouvrage porte ainsi a notre connaissance tout a la fois des doctrines dogmatiques - comme la logique stoicienne - auxquelles nous aurions moins acces sans son temoignage, et une bonne partie de l'argumentaire sceptique deploye depuis la renaissance du pyrrhonisme, a l'epoque d'Enesideme, qui serait autrement perdue.

We present an age-structured model for erythropoiesis in which the mortality of mature cells is described empirically by a physiologically realistic probability distribution of survival times. Under some assumptions, the model can be transformed into a system of delay differential equations with both constant and distributed delays. The stability of the equilibrium of this system and possible Hopf bifurcations are described for a number of probability distributions. Physiological motivation and interpretation of our results are provided.

For the theorists of crisis, the revolutionary state comes into existence through violence, and due to its inability to provide an authoritative katechon (restrainer) against internal and external violence, it perpetuates violence until it self-destructs. Writing during extreme economic depression and growing social and political violence, the crisis theorists––Joseph de Maistre, Juan Donoso Cortés, and Carl Schmitt––each sought to blame the chaos of their time upon the Janus-faced postrevolutionary ideals of liberalism and socialism by urging a return to pre-revolutionary moral (...) and religious values. They are united by three counterrevolutionary principles, all of which are purported to remedy revolutionary violence: traditional constitutional fidelity, the philosophy of the decision, and opposition to bourgeois liberalism. This essay is followed by the first complete English translation and publication of Donoso’s letter of October 24, 1851, which contains Donoso’s only reference to the “discussing class,” a political entity later popularized by Schmitt in his 1922 work Political Theology.

The use of predictive machine learning algorithms is increasingly common to guide or even take decisions in both public and private settings. Their use is touted by some as a potentially useful method to avoid discriminatory decisions since they are, allegedly, neutral, objective, and can be evaluated in ways no human decisions can. By (fully or partly) outsourcing a decision process to an algorithm, it should allow human organizations to clearly define the parameters of the decision and to, in principle, (...) remove human biases. Yet, in practice, the use of algorithms can still be the source of wrongful discriminatory decisions based on at least three of their features: the data-mining process and the categorizations they rely on can reconduct human biases, their automaticity and predictive design can lead them to rely on wrongful generalizations, and their opaque nature is at odds with democratic requirements. We highlight that the two latter aspects of algorithms and their significance for discrimination are too often overlooked in contemporary literature. Though these problems are not all insurmountable, we argue that it is necessary to clearly define the conditions under which a machine learning decision tool can be used. We identify and propose three main guidelines to properly constrain the deployment of machine learning algorithms in society: algorithms should be vetted to ensure that they do not unduly affect historically marginalized groups; they should not systematically override or replace human decision-making processes; and the decision reached using an algorithm should always be explainable and justifiable.

Henri Lefebvre has considerable claims to be the greatest living philosopher. His work spans some sixty years and includes original work on a diverse range of subjects, from dialectical materialism to architecture, urbanism and the experience of everyday life. The Production of Space is his major philosophical work and its translation has been long awaited by scholars in many different fields. The book is a search for a reconciliation between mental space and real space. In the course of his (...) exploration, Henri Lefebvre moves from metaphysical and ideological considerations of the meaning of space to its experience in the everyday life of home and city. He seeks, in other words, to bridge the gap between the realms of theory and practice, between the mental and the social, and between philosophy and reality. In doing so, he ranges through art, literature, architecture and economics, and further provides a powerful antidote to the sterile and obfuscatory methods and theories characteristic of much recent continental philosophy. This is a work of great vision and incisiveness. It is also characterized by its author's wit and by anecdote, as well as by a deftness of style which Donald Nicholson-Smith's sensitive translation precisely captures. (shrink)

La Praxis est le point de départ et le point d'arrivée du matérialisme dialectique. Ce mot désigne philosophiquement ce que le sens commun appelle : "la vie réelle", cette vie qui est à la fois plus prosaïque et plus dramatique que celle de l'esprit, spéculatif. Le but du matérialisme dialectique n'est autre que l'expression lucide de la Praxis, du contenu réel de la vie - et corrélativement la transformation de la Praxis actuelle en une pratique sociale consciente, cohérente et libre. (...) Le but théorique et le but pratique - la connaissance et l'action créatrice - sont inséparables. HENRI LEFEBVRE. (shrink)

In much of the current academic and public discussion, conspiracy theories are portrayed as a negative phenomenon, linked to misinformation, mistrust in experts and institutions, and political propaganda. Rather surprisingly, however, philosophers working on this topic have been reluctant to incorporate a negatively evaluative aspect when either analyzing or engineering the concept conspiracy theory. In this paper, we present empirical data on the nature of the concept conspiracy theory from five studies designed to test the existence, prevalence and exact form (...) of an evaluative dimension to the ordinary concept conspiracy theory. These results reveal that, while there is a descriptive concept of conspiracy theory, the predominant use of conspiracy theory is deeply evaluative, encoding information about epistemic deficiency and often also derogatory and disparaging information. On the basis of these results, we present a new strategy for engineering conspiracy theory to promote theoretical investigations and institutional discussions of this phenomenon. We argue for engineering conspiracy theory to encode an epistemic evaluation, and to introduce a descriptive expression—such as ‘conspiratorial explanation’—to refer to the purely descriptive concept conspiracy theory.

Les démocraties s’articulent autour de deux pôles qui ne se réduisent pas l’un à l’autre, mais qui doivent communiquer constamment : la société civile et l’État. Or, l’équilibre à rechercher entre ces deux éléments est mis à mal par la consolidation de l’État administratif qui tend à autonomiser son action par rapport au reste de la société ; la société civile y est d’ordinaire exclue des prises de décisions. Cette exclusion peut toutefois être considérée positivement ou négativement. Comme il sera (...) discuté à partir des philosophies de John Dryzek et d’Iris Marion Young, on devrait tenter de penser à la fois l’inclusion de la société civile dans certaines prises de décisions étatiques et son indépendance pour favoriser sa dimension critique envers l’État. De là, l’État administratif peut être considéré simultanément comme une opportunité de démocratisation et comme une évolution de l’État à surveiller et à critiquer. (shrink)

Generation of Animals is one of Aristotle's most mature, sophisticated, and carefully crafted scientific writings. His overall goal is to provide a comprehensive and systematic account of how animals reproduce, including a study of their reproductive organs, what we would call fertilization, embryogenesis, and organogenesis. In this book, international experts present thirteen original essays providing a philosophically and historically informed introduction to this important work. They shed light on the unity and structure of the Generation of Animals, the main theses (...) that Aristotle defends in the work, and the method of inquiry he adopts. They also open up new avenues of exploration of this difficult and still largely unexplored work. The volume will be essential for scholars and students of ancient philosophy as well as of the history and philosophy of science. (shrink)

Contemporary political philosophers are often uncomfortable with the notion that a conception of the good life can be developed out of liberalism. Liberalism, they say, should remain neutral out of respect for pluralism. Early liberals of the nineteenth century, however, understood their project as a vindication of the good life, along with a diagnosis of what threatens it. This article attempts to build a conception of the good life from liberal values and sensibilities, yet not run afoul of the need (...) to respect pluralism. It draws on early and contemporary liberals, as well as popular culture, to sketch a way of life that is fulfilling and available for us today. (shrink)
