Models are of central importance in many scientific contexts. The centrality of models such as inflationary models in cosmology, general-circulation models of the global climate, the double-helix model of DNA, evolutionary models in biology, agent-based models in the social sciences, and general-equilibrium models of markets in their respective domains is a case in point (the Other Internet Resources section at the end of this entry contains links to online resources that discuss these models). Scientists spend significant amounts of time building, (...) testing, comparing, and revising models, and much journal space is dedicated to interpreting and discussing the implications of models.

(...) Scientists spend a great deal of time building, testing, comparing and revising models, and much journal space is dedicated to introducing, applying and interpreting these valuable tools. In short, models are one of the principal instruments of modern science. -/- Philosophers are acknowledging the importance of models with increasing attention and are probing the assorted roles that models play in scientific practice. The result has been an incredible proliferation of model-types in the philosophical literature. Probing models, phenomenological models, computational models, developmental models, explanatory models, impoverished models, testing models, idealized models, theoretical models, scale models, heuristic models, caricature models, didactic models, fantasy models, toy models, imaginary models, mathematical models, substitute models, iconic models, formal models, analogue models and instrumental models are but some of the notions that are used to categorize models. While at first glance this abundance is overwhelming, it can quickly be brought under control by recognizing that these notions pertain to different problems that arise in connection with models. For example, models raise questions in semantics (what is the representational function that models perform?), ontology (what kind of things are models?), epistemology (how do we learn with models?), and, of course, in philosophy of science (how do models relate to theory?; what are the implications of a model based approach to science for the debates over scientific realism, reductionism, explanation and laws of nature?).

The formalism of quantum mechanics provides us with the probabilities for certain events to occur—this much is uncontroversial. But how are we to understand these probabilities? The essays in this special issue approach this question from different angles. The first three contributions take as their point of departure the philosophy of probability and discuss what the two main outlooks—objective and subjective interpretations of probability—have to offer in the context of quantum mechanics. The following five papers explore the question of how (...) probabilities in particular interpretations of quantum mechanics—modal interpretations, relative state interpretations, Bohmian mechanics, and GRW theory—can be interpreted. The last three essays address specific issues: non-standard probability and algebraic quantum field theory, quantum propensities, and the relation between decoherence and the interpretation of probability.

The roles models play in science have long been recognised and sparked rich and varied philosophical debates. In recent years attention has also been paid to the computational techniques used in the sciences, and the question arose what the implications were of the use of computer simulations for our understanding of scientific modelling, and science more generally. This was the subject of the conference “Models and Simulations”, which took place at the IHPST in Paris in June 2006. Selected papers of (...) that conference appeared in a special issue of this journal (Synthese 169(3) (2009)). After the conference there was a general feeling that there still was much ground to cover, and so we decided to organize a follow up a year later. “Models and Simulations 2” took place in October 2007 at the Tilburg Center for Logic and Philosophy of Science (TiLPS) in the Netherlands. The conference was made possible due to generous financial support from IHPST (Paris, CNRS), Universitat de Barcelona, TiLPS (Tilburg Center for Logic and Philosophy of Science) and the Evert Willem Beth Foundation. The papers in this special issue were presented at the conference and selected after a double-blind review process. We would like to thank the authors and referees of the papers for their work, and Vincent Hendricks and John Symons for their support of the project of another special issue on models and simulations.

We reconsider the Nagelian theory of reduction and argue that, contrary to a widely held view, it is the right analysis of intertheoretic reduction. The alleged difficulties of the theory either vanish upon closer inspection or turn out to be substantive philosophical questions rather than knock-down arguments.

Various scientific theories stand in a reductive relation to each other. In a recent article, we have argued that a generalized version of the Nagel-Schaffner model (GNS) is the right account of this relation. In this article, we present a Bayesian analysis of how GNS impacts on confirmation. We formalize the relation between the reducing and the reduced theory before and after the reduction using Bayesian networks, and thereby show that, post-reduction, the two theories are confirmatory of each other. We (...) then ask when a purported reduction should be accepted on epistemic grounds. To do so, we compare the prior and posterior probabilities of the conjunction of both theories before and after the reduction and ask how well each is confirmed by the available evidence. (shrink)

Amidst contemporary culture’s obsession with superheroes as the basis of the new mythologies of our day, and numerous religious communities’ ‘sterilized’ version of Jesus, the church has to rediscover the paradoxical life and teachings of Jesus, as narrated in the Gospel of Mark. Within the honour-and-shame-based Mediterranean culture, within which Mark was written, Jesus’ atypical demeanour and his radical teachings on self-sacrifice, coupled with his shameful death, were perplexing. His opponents did not find any proof in his scandalous teachings and (...) inglorious outward appearance to confirm his messianic claims. In terms of the present obsession with superheroes, Jesus was never in a costume in public. He did not take on a temporary public persona in a staged drama en route to the cross. At all times, Jesus was the slave-like Son of God who came to serve and lay down his own life as a ransom for many (Mk 10:45). The crucified Jesus, stripped of all honour and godforsaken, is the paradoxical sign and physical embodiment of the kingdom of God. The risen Jesus is no different. He still is who he is. This largely undiscovered Jesus of Mark’s Gospel must capture the imagination of the church all over again, the kind of imagination that elicits admiration, amazement and life-change. Only when the church begins to embody the kenotic route of Jesus that it will become clear to her and others that she, in fact, possesses paradoxical ‘superpowers’ – the self-sacrificing kind.

On February 22, 1987, the Congregation for the Doctrine of the Faith published the Donum Vitae Instruction. Twenty years later, on February 22, 2007, Pope Benedict XVI asked for an update of this Instruction. According to the Donum Vitae Instruction of 1987, the principle of the holiness of life imposes respect for human persons from the very beginning of human life. In these past 20 years, new medical techniques have raised fresh ethical issues that are to be addressed by the (...) Roman Catholic Church Magisterium. The Roman Catholic Church, in its update of the Instruction planned for 2007, will have to explain how civil law is to be regulated according to the fundamental norms of the moral law. The moral message of the new Donum Vitae will be to affirm the substance of human justice: respect for human life, as expressed in the resolve not to infringe on, or to protect such life. Even in a post-Christian Europe, this theological message can be understood if it is true that Europe is marked by the principle of the absolute protection of human life. (shrink)

Over three centuries after the 1711 discovery in the choir of Notre-Dame in Paris of a square-section stone bas-relief with depictions of several deities, both Gaulish and Roman, the blocks comprising it were analyzed as a symbol of Parisian power, if not autonomy, vis-à-vis the Roman Empire. Variously considered as local, national, or imperial representations, the blocks were a constant object of admiration, interrogation, and speculation among antiquarians of the Republic of Letters. They were also boundary objects – (...) products of the emergence of a Parisian archeology dated from 1711. If this science reflected the tensions and ambiguities of a local regime of knowledge situated in a national context, it also helped to coordinate archeological work between different institutions and actors. This paper would like to assess the specific role played by the Pillar of the Boatmen as a fetish object in this process. To what extent could an archeological artifact influence this reshaping of urban representation, this change of scales? By following the three-century career of the pillar’s blocks as composite objects, which some have identified as merely stones or a column, it is possible to understand the multiple dimensions that defined the object as archeological – as an artifact that contributed to the relocating of the historical city center – and the multiple approaches that transform existing remains into knowledgeable objects.

Stephan H. Pfürtner (1922-2012) was a Catholic theologian who in the last stage of his academic career taught Social Ethics in the Department of Protestant Theology at Philipps-University in Marburg. The text, originally a lecture in commemoration of Stephan Pfürtner and his work, shows the close connection between biography and theology, between ethical experience and ethical reflection in his case. Empathetic Courage is shown by him in his successful effort to save three young Jewish women from death in the Concentration (...) Camp of Stutthof near Danzig in 1944. Ecumenical Resistance is performed by a group of young Christians around four ministers who became sentenced to death in 1943. A Liberated Conscience is decisive for Pfürtner’s position in a deep conflict with the Roman-Catholic Church on the ethics of human sexuality. Ethics of Reponsibility is the conception that he develops in his Marburg years. Evangelical Catholicity characterizes the spiritual dimension of Stephan Pfürtner’s legacy. (shrink)

Cette nouvelle enquête sur le patrimoine narratif de tradition orale dans les Alpes de la Savoie s’est inscrite dans la continuité des enquêtes de Charles Joisten, commencées dès les années 1950 et qui ont donné les recueils de contes et de récits de croyance rendus disponibles au tournant de ce siècle. Seul ce type d’enquête directe s’est révélé capable de nous permettre — en tirant parti des moyens disponibles de nos jours, notamment d’enregistrement — de donner le jour à de (...) nouveaux exemplaires de cette matière de l’oralité. Nous exposerons ici les aspects de notre expérience sur plusieurs années de terrain ayant abouti à plusieurs publications. Nous mettrons l’accent sur les questions de forme narrative et de fond dans l’univers de l’oralité, tout particulièrement en ce qui concerne la narration des croyances, dans leurs contextes historiques. Our new survey on the narrative heritage from oral tradition in the Alps of Savoy has been performed in the continuity of Charles Joisten’s opus, gathered since the 50s, which was made fully available in collections of tales and belief narratives about the turn of this century. This type of direct investigation in face-to-face interaction—taking advantage of current means of recording available today—has proved to remain still nowadays the only one able to elicit new data. The main aspects of our field experience in the long term which resulted in several publications about tales and belief narratives will be questionned. While putting the emphasis on narrative form and substantive issues in the realm of orality, we will focus particularly on belief narratives in their historical contexts. (shrink)

While the paradigm of utility maximisation has formed the basis of the majority of applications in discrete choice modelling for over 40 years, its core assumptions have been questioned by work in both behavioural economics and mathematical psychology as well as more recently by developments in the RUM-oriented choice modelling community. This paper reviews the basic properties with a view to explaining the historical pre-eminence of utility maximisation and addresses the question of what departures from the paradigm may be necessary (...) or wise in order to accommodate richer behavioural patterns. We find that many, though not all, of the behavioural traits discussed in the literature can be approximated sufficiently closely by a random utility framework, allowing analysts to retain the many advantages that such an approach possesses.

Subjectivism about well-being holds that an object contributes to one's well-being to the extent that one has a pro-attitude toward this object under certain conditions. Most subjectivists have contended that these conditions should be ideal. One reason in favor of this idea is that when people adapt their pro-attitudes to situations of oppression, the levels of well-being they may attain is diminished. Nevertheless, I first argue that appealing to idealized conditions of autonomy or any other condition to erase or replace (...) adaptive pro-attitudes is mistaken. Second, I show that the most natural version of subjectivism that does not appeal to any such idealizing condition can explain why the well-being of people having adaptive pro-attitudes should not be restricted to the fulfillment of these pro-attitudes. In sum, the existence of adaptive preferences does not militate in favor of the introduction of conditions of idealization but against it. (shrink)

Local sustainable food systems have captured the popular imagination as a progressive, if not radical, pillar of a sustainable food future. Yet these grassroots innovations are embedded in a dominant food regime that reflects productivist, industrial, and neoliberal policies and institutions. Understanding the relationship between these emerging grassroots efforts and the dominant food regime is of central importance in any transition to a more sustainable food system. In this study, we examine the encounters of direct farm marketers with food safety (...) regulations and other government policies and the role of this interface in shaping the potential of local food in a wider transition to sustainable agri-food systems. This mixed methods research involved interview and survey data with farmers and ranchers in both the USA and Canada and an in-depth case study in the province of Manitoba. We identified four distinct types of interactions between government and farmers: containing, coopting, contesting, and collaborating. The inconsistent enforcement of food safety regulations is found to contain progressive efforts to change food systems. While government support programs for local food were helpful in some regards, they were often considered to be inadequate or inappropriate and thus served to coopt discourse and practice by primarily supporting initiatives that conform to more mainstream approaches. Farmers and other grassroots actors contested these food safety regulations and inadequate government support programs through both individual and collective action. Finally, farmers found ways to collaborate with governments to work towards mutually defined solutions. While containing and coopting reflect technologies of governmentality that reinforce the status quo, both collaborating and contesting reflect opportunities to affect or even transform the dominant regime by engaging in alternative economic activities as part of the ‘politics of possibility’. Developing a better understanding of the nature of these interactions will help grassroots movements to create effective strategies for achieving more sustainable and just food systems. (shrink)

Since at least the mid-1980s claims have been made for rationality in rats. For example, that rats are capable of inferential reasoning (Blaisdell, Sawa, Leising, & Waldmann, 2006; Bunsey & Eichenbaum, 1996), or that they can make adaptive decisions about future behavior (Foote & Crystal, 2007), or that they are capable of knowledge in propositional-like form (Dickinson, 1985). The stakes are rather high, because these capacities imply concept possession and on some views (e.g., Rödl, 2007; Savanah, 2012) rationality indicates self-consciousness. (...) I evaluate the case for rat rationality by analyzing 5 key research paradigms: spatial navigation, metacognition, transitive inference, causal reasoning, and goal orientation. I conclude that the observed behaviors need not imply rationality by the subjects. Rather, the behavior can be accounted for by noncognitive processes such as hard-wired species typical predispositions or associative learning or (nonconceptual) affordance detection. These mechanisms do not necessarily require or implicate the capacity for rationality. As such there is as yet insufficient evidence that rats can reason. I end by proposing the ‘Staircase Test,’ an experiment designed to provide convincing evidence of rationality in rats. (shrink)

In this paper, I propose a reductive account of intentions which I call a gate-based reductive account. In contrast with other reductive accounts, however, the reductive basis of this account is not limited to desires, beliefs and judgments. I suggest that an intention is a complex state in which a predominant desire toward a plan is not inhibited by a gate mechanism whose function is to assess the comparison of our desires given the stakes at hand. To vindicate this account, (...) I rely on several considerations: the similarity between epistemic feelings and the feeling of being decided that tells us that we have an intention, the necessity of postulating a gate mechanism to explain our hesitating behavior, and the tight link that exists between the realization of our actions and our desires. In agreement with non-reductivists, I nevertheless acknowledge that intentions encompass plans, although I emphasize that the planning capacity must also be dependent on our motivational life and the general evaluative mechanisms that explains our emotions.

The basic premise of the host‐defense theory is that genomic imprinting, the parent‐of‐origin expression of a subset of mammalian genes, derives from mechanisms originally dedicated to silencing repeated and retroviral‐like sequences that deeply colonized mammalian genomes. We propose that large clusters of tandemly‐repeated C/D‐box small nucleolar RNAs (snoRNAs) or microRNAs represent a novel category of sequences recognized as “genomic parasites”, contributing to the emergence of genomic imprinting in a subset of chromosomal regions that contain them. Such a view is supported (...) by evidence derived from studies of the imprinted snoRNA‐ and/or miRNA‐encoding Dlk1‐Dio3, Snurf‐Snrpn, Sfbmt2, and C19MC domains. While adding a new piece to the challenging puzzle of mammalian genome history, this hypothesis also reinforces the notion that dissecting the features and molecular mechanisms that discriminate between “foreign” and “endogenous” sequences is of crucial importance in the field of mammalian epigenetics.

Dans cette étude, nous examinons l'influence de quelques éléments caractéristiques des doctrines psychologique et eschatologique de Porphyre, dont certains correspondent à des idées de Plotin, sur l'analyse qu'Augustin propose des différentes sortes de visiones dans le De Trinitate et le De Genesi ad litteram.This study focuses on the influence of Porphyry's psychology and eschatology on Augustine's account of the different kinds of visiones, as it is set out in the treatises De Trinitate and De Genesi ad litteram.

Cette étude vise à montrer comment Synésios de Cyrène, ayant adopté deux doctrines vraisemblablement porphyriennes (touchant l’enkuklios paideia et le pneuma en tant qu’organe de l’imagination), les articule en fonction d’une double préoccupation: celle d’un progrès intérieur de l’âme qui soit une progression ordonnée via les logoi, et celle d’une communication intime avec la divinité (voire de salut personnel), via une phantasia purifiée. Ce double souci de conversion intérieure, manifesté dans le diptyque littéraire constitué par le Dion: ou du genre (...) de vie conforme à son modèle et le traité Des songes (publiés tous deux en 405), le conduit à concevoir une forme d’écriture intime qui serait une écriture philosophiquement adéquate au mode de vie auquel, idéalement, cet homme public et ce styliste hors pair envisage alors de se consacrer. Mais dans la réalité de son existence d’homme de lettres, et donc dans la pratique de son écriture, cette conversion à l’intime ne correspond qu’à un assez bref moment d’anachorèse vouée à l’étude et donc à soi-même – ultime refuge, plus rêvé que réalisé, de l’ethos platonicien, tel qu’il se le représentait.

The 2005 Avignon Theatre Festival sparked a vast controversy about the insistent presence of bodies (whether wounded, broken, or humiliated) on stage. Without subscribing to the reactionary critical response to the Festival, it is legitimate to return to the debate in order to question the ubiquity of the “victim body” in contemporary theatre. Such representations, far from being heterodox, are in fact part of the massive ideology of “the ethical”, as diagnosed by Alain Badiou. The oppressed body thus tends to (...) be assimilated to the body of the victim. The result is the obliteration of the resistance of subjects to their oppression, or of their active response to it, theatre being reduced to the maxims of a democratic materialism: “there are only bodies and languages”.

Foucault’s Forgotten Marxism. This article tries to point out several methodological issues concerning Foucault’s Surveiller et punir, such as the equivocal status of some of Foucault’s main concepts, or the assumed homogeneity of the various disciplinary institutions analyzed in this book.

In the (...) opinion of the author, only in as much as this heritage is accepted and seriously taken into account, shall Foucault’s concepts and theses regain their political and critical pertinence.

Les récents débats autour du délit de manipulation mentale amènent à s'interroger sur la notion d'influence et sur l'impact des recherches faites dans ce domaine. Ce délit repose sur l'idée que des techniques de manipulation efficaces existent et que par leur utilisation, on pourrait manipuler autrui. Suivant cette conception asymétrique de l'influence, la cible devient l'instrument du désir de la source et dans ce cas, il est nécessaire de se protéger de ces influences qui peuvent être néfastes. Si des travaux (...) expérimentaux de psychologie sociale montrent l'efficacité de certaines techniques d'influence et de manipulation, ils doivent cependant être mis en perspective. Nombre d'expériences et de théories montrent que l'influence n'est fondamentalement pas un rapport asymétrique. Mais hélas, ces travaux sont négligés tant ils ne cadrent pas avec ce prototype de l'influence qui domine à la fois en psychologie sociale et dans le sens commun.Recent debate on the abuse of mental manipulation has raised questions about the concept of influence and the impact of the research in this field. This abuse is based on the idea that with effective techniques of manipulation can be used to mentally control others. According to this asymmetrical model of influence, the target becomes the instrument of the desire of the source and therefore must be protected from such dangerous and negative influences. If certain experiments in social psychology show the effectiveness of certain techniques of influence and manipulation, such effects must be analyzed with due care. Many experiments and theories show that influence is not essentially asymmetrical. Unfortunately, such studies tend to be ignored because they differ from the accepted model of influence which dominates both in social psychology and in common sense. (shrink)

We should not understand in this title "What does not return to the same" the announcement of a return to Levinas, but rather of what the word or concept of "return" could mean in Levinas's work. There is perhaps no better way of misunderstanding Levinas than imposing on his philosophical gesture the interpretative grid of a "horizon of return". This article will attempt to dismantle the strategies of reading which stipulate that Levinas's philosophy is one of "return". In this way (...) we shall reveal the complexity of Levinasian thought, and that, beyond the numerous slogans, there are the ones of a "return" or of its simple contrary, the ones of a "philosophy of exile".
