L'interrogation sur le rôle que jouent aujourd'hui les convictions religieuses en philosophie des sciences peut paraître une démarche surprenante, car trop souvent la religion est rejetée hors du champ de l'enquête philosophique. Cet ouvrage ose au contraire demander dans quelle mesure les options religieuses d'un penseur influencent sa conception de l'ordre cosmique. L'examen du concept de loi de la nature s'inscrit dans une quête plus large : il permet de tester la façon dont les choix épistémologiques d'un individu dépendent de (...) sa vision du monde et ainsi de porter une attention particulière aux interactions entre science, épistémologie et religion. L'étude porte sur quatre figures des plus marquantes du débat contemporain sur les lois de la nature : David Armstrong, Nancy Cartwright, David Lewis et Bas van Fraassen. L'analyse de leurs écrits, approfondie d'entretiens personnels, fait ressortir pour chacun les liens qui existent entre sa posture religieuse et son compte rendu de la légalité naturelle. (shrink)

La figure de l’entrepreneur est aujourd’hui utilisée dans une grande variété de discours publics. Ce travail cherche à remonter à l’une des sources théoriques de la constitution de cette figure : la théorie de l’entrepreneur de Schumpeter (1911a et 1911b). Ce retour montre que Schumpeter, dans son contexte intellectuel et théorique, est amené à importer une anthropologie philosophique en économie, celle de Nietzsche, auteur largement lu dans l’Autriche du début du xxe siècle. En transposant, à l’intérieur de sa théorie économique, (...) certaines caractéristiques majeures du grand homme créatif nietzschéen dans la figure de l’entrepreneur, Schumpeter développe une explication originale de la nature dynamique du marché et de l’évolution économique. Néanmoins il importe aussi de Nietzsche une série d’ambiguïtés, notamment en ce qui concerne l’origine de l’exceptionnalité individuelle de l’entrepreneur, et plus particulièrement de sa puissance créatrice. Une seconde ambiguïté est très largement héritée, qui concerne l’extension du modèle de l’individu entrepreneur : constitue-t-il une théorie de l’action valable pour tous les individus ou uniquement pour un type d’individus particuliers? Comment concilier exceptionnalité de l’entrepreneur et norme d’un entreprenariat pour tous? La dernière partie de ce travail s’attache ainsi à explorer ces ambiguïtés, qui apparaissent chez Schumpeter et ses successeurs, notamment Israël Kirzner.Codes JEL : B13, B25, B31, B40. (shrink)

This book argues that sometimes we have reasons to overcome repression and that these reasons are unlike any other reasons for action typically recognized by philosophers.

Altersarmut, Bildungsunterschiede, eine wachsende Kluft zwischen Arm und Reich - die deutsche Gesellschaft spaltet sich, und viele fordern mehr Soziale Gerechtigkeit. Die Autorin untersucht, wie sich das Verstandnis von Sozialer Gerechtigkeit in Philosophie und Politik gewandelt hat, und hinterfragt, inwieweit Politiker Soziale Gerechtigkeit als Akzeptanzmittel fur ihre Entscheidungen nutzen.

Recent work in quantum information science has produced a revolution in our understanding of quantum entanglement. Scientists now view entanglement as a physical resource with many important applications. These range from quantum computers, which would be able to compute exponentially faster than classical computers, to quantum cryptographic techniques, which could provide unbreakable codes for the transfer of secret information over public channels. These important advances in the study of quantum entanglement and information touch on deep foundational issues in both physics (...) and philosophy. This interdisciplinary volume brings together fourteen of the world's leading physicists and philosophers of physics to address the most important developments and debates in this exciting area of research. It offers a broad spectrum of approaches to resolving deep foundational challenges - philosophical, mathematical, and physical - raised by quantum information, quantum processing, and entanglement. This book is ideal for historians, philosophers of science and physicists"--Provided by publisher. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.3 (2003) 227-231 [Access article in PDF] World Traveling as a Clinical Methodology for Psychiatric Care Suzanne M. Jaeger Keywords embodiment, dialogical consciousness, interpersonal communication, epistemic responsibility, self-knowledge, understanding IN HER ARTICLE "Moral Tourists and World Travelers," Nancy Potter suggests a way in which psychiatrists and psychologists could gain a better understanding of their mentally ill patients' experiences. Rather than assuming that hallucinations and (...) incoherent speech and behavior are merely senseless disconnections from reality, Potter argues that mental health care clinicians ought to spend time engaging patients on their own terms. Even when mental illness is a result of brain disease, much can be learned about the patient's experiences of their disease by temporarily setting aside the scientific frameworks of diagnosis and medical treatment. Potter uses Maria Lugones' concept of world traveling and recommends playfully accepting, and even entering into the patient's world (Lugones 1990). She calls world traveling a methodology and explains it in some detail. Moreover, at the close of her essay, Potter suggests that clinicians have a moral obligation to understand the mentally ill patient's world from the patient's perspective. This obligation is based on an appeal to our sense of what it is to be a responsible knower who attends to issues of trust and truth. Relying on arguments made by Lorraine Code (1987), Potter asserts that to try to understand the other's perspective is the responsible thing to do.My discussion focuses on the notion of play to which Potter appeals, as well as on what she sees as the moral obligation of clinicians to communicate with their mentally ill patients in extra-professional ways. This moral obligation arises because (a) the theoretical and professional frameworks of medical science are seen as inadequate, and (b) playfulness opens up mutually respectful, authentic interaction between persons. I generally agree with Potter's claims, and I want to situate them in the wider framework of an epistemological debate about the status of our knowledge of others. A broader context will help to elucidate the strengths of Potter's analysis as well as some points for critical discussion. I begin with the relationship of trust between clinicians and patients.Few people would disagree with the claim that patients need to be able to trust that their physicians are not harming them, but helping them to get better. If patients feel misunderstood, they will not trust their caretakers. This is probably even truer for psychiatric patients, whose conditions and loss of autonomy make establishing trust even more challenging. Psychiatric patients [End Page 227] often have their own ways of compensating for the symptoms of their mental illness. If either their will to survive or their compensatory strategies go unrecognized or misinterpreted, patients may respond by rejecting the well-intentioned efforts of caretakers to restore them to a degree of ease, measured as it must be by the standards of the professionals under whose care the patient remains. 1 Despite the fact that these standards are established through scientific testing procedures for the treatment of diseases, they may be experienced by patients as indifferent to the particular and unique features of their condition. Nestled within the issue of trust is thus a question of truth.Although current scientific knowledge of the human brain, and of human behavior, has made available a range of sophisticated therapies and psychotropic drugs, there are still many mental illnesses that leave families and clinicians wondering whether the treatment plans are providing any help. Alzheimer's disease and schizophrenia are two examples. There is a difference between, on the one hand, containing the patient's behavior by admitting the patient to a psychiatric ward and managing symptoms with psychotropic medications, and, on the other hand, understanding what is happening for the patient, from his or her perspective. Although psychiatric patients may not have a realistic sense of either their abilities or the extent and nature of their disease, there may be much about their experiences that ought to be known and understood by the professionals caring for them...

Heidegger hielt die unter dem Titel Geschichte des Zeitbegriffs angekundigte Vorlesung im Sommer-Semester 1925 in der Marburger Universitat. Er gelangte jedoch nicht mehr zur Ausfuhrung der zentralen Thematik. Der Themenkreis der Vorlesung ist mit der Nennung des Untertitels abgesteckt: Prolegomena zu einer Phanomenologie von Geschichte und Natur. Heideggers thematische Uberlegungen beginnen mit einer Kennzeichnung der Situation von Philosophie und Wissenschaft in der zweiten Halfte des 19. Jahrhunderts und stellen das seiner Deutung nach entscheidende Ereignis dieser Zeit heraus: den Durchbruch der (...) Phanomenologie als philosophische Forschung. Er untersucht ihre wesentlichen Entdeckungen, verteidigt sie gegen Missverstandnisse, um dann seinerseits Kritik vorzubringen, wo die Phanomenologie ihrer Forderung zu den Sachen selbst nicht gerecht wird.

Evolutionary systems biology (ESB) aims to integrate methods from systems biology and evolutionary biology to go beyond the current limitations in both fields. This article clarifies some conceptual difficulties of this integration project, and shows how they can be overcome. The main challenge we consider involves the integration of evolutionary biology with developmental dynamics, illustrated with two examples. First, we examine historical tensions between efforts to define general evolutionary principles and articulation of detailed mechanistic explanations of specific traits. Next, these (...) tensions are further clarified by considering a recent case from another field focused on developmental dynamics: stem cell biology. In the stem cell case, incompatible explanatory aims block integration. Experimental approaches aim at mechanistic explanation while dynamical system models offer explanation in terms of general principles. We then discuss an ESB case in which integration succeeds: search for general attractors using a dynamical systems framework synergizes with the experimental search for detailed mechanisms. Contrasts between the positive and negative cases suggest general lessons for achieving an integrated understanding of developmental and evolutionary dynamics. The key integrative move is to acknowledge two complementary aims, both relevant to explanation: identifying the space of possible dynamic states and trajectories, and mechanistic understanding of causal interactions underlying a specific phenomenon of interest. These two aims can support one another in a joint project characterizing dynamic aspects of evolving lineages. This more inclusive project can lead to insights that cannot be reached by either approach in isolation. (shrink)

The positive operator (valued) measures (POMs) allow one to generalize the notion of observable beyond the traditional one based on projection valued measures (PVMs). Here, we argue that this generalized conception of observable enables a consistent notion of unsharp reality and with it an adequate concept of joint properties. A sharp or unsharp property manifests itself as an element of sharp or unsharp reality by its tendency to become actual or to actualize a specific measurement outcome. This actualization tendency—or potentiality—of (...) a property is quantified by the associated quantum probability. The resulting single-case interpretation of probability as a degree of reality will be explained in detail and its role in addressing the tensions between quantum and classical accounts of the physical world will be elucidated. It will be shown that potentiality can be viewed as a causal agency that evolves in a well-defined way. (shrink)

Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to hold the conditional per-word entropy associated with each word constant, which would facilitate efficient information transfer (Genzel & Charniak, 2002). This hypothesis implies that the conditional (contextualized) probabilities of linguistic units (...) affect speakers’ preferences during production. Here, we extend this work in two ways. First, we explore how preceding cues are integrated into contextualized probabilities, a question which so far has received little to no attention. Specifically, we investigate how a cue's maximal informativity about upcoming words (the cue's effectiveness) decays as a function of the cue's recency. Based on properties of linguistic discourses as well as properties of human memory, we analytically derive a model of cue effectiveness decay and evaluate it against cross-linguistic data from 12 languages. Second, we relate the information theoretic accounts of discourse production to well-established mechanistic (activation-based) accounts: We relate contextualized probability distributions over words to their relative activation in a lexical network given preceding discourse.

There is now considerable evidence that human sentence processing is expectation based: As people read a sentence, they use their statistical experience with their language to generate predictions about upcoming syntactic structure. This study examines how sentence processing is affected by readers' uncertainty about those expectations. In a self-paced reading study, we use lexical subcategorization distributions to factorially manipulate both the strength of expectations and the uncertainty about them. We compare two types of uncertainty: uncertainty about the verb's complement, reflecting (...) the next prediction step; and uncertainty about the full sentence, reflecting an unbounded number of prediction steps. We find that uncertainty about the full structure, but not about the next step, was a significant predictor of processing difficulty: Greater reduction in uncertainty was correlated with increased reading times. We additionally replicated previously observed effects of expectation violation, orthogonal to the effect of uncertainty. This suggests that both surprisal and uncertainty affect human RTs. We discuss the consequences for theories of sentence comprehension. (shrink)

In the article ”Against Physicalism-plus-God: How Creation Accounts for Divine Action in the World’, I defined a framework which allows us to make some progress in our understanding of how God acts in the world. In the present article, I apply this framework to the specific question of chance events. I show that chance does not provide an explanation for special divine action. Nevertheless, chance does not hamper God’s ability to act in the world, and creation provides a framework for (...) the understanding of chance, which is akin to what we see in modern science.

The logic of genetic discovery has changed little over time, but the focus of biology is shifting from simple genotype–phenotype relationships to complex metabolic, physiological, developmental, and behavioral traits. In light of this, the traditional reductionist view of individual genes as privileged difference‐making causes of phenotypes is re‐examined. The scope and nature of genetic effects in complex regulatory systems, in which dynamics are driven by regulatory feedback and hierarchical interactions across levels of organization are considered. This review argues that it (...) is appropriate to treat genes as specific actual difference‐makers for the molecular regulation of gene expression. However, they are often neither stable, proportional, nor specific as causes of the overall dynamic behavior of regulatory networks. Dynamical models, properly formulated and validated, provide the tools to probe cause‐and‐effect relationships in complex biological systems, allowing to go beyond the limitations of genetic reductionism to gain an integrative understanding of the causal processes underlying complex phenotypes.

This study provides evidence for implicit learning in syntactic comprehension. By reanalyzing data from a syntactic priming experiment (Thothathiri & Snedeker, 2008), we find that the error signal associated with a syntactic prime influences comprehenders' subsequent syntactic expectations. This follows directly from error‐based implicit learning accounts of syntactic priming, but it is unexpected under accounts that consider syntactic priming a consequence of temporary increases in base‐level activation. More generally, the results raise questions about the principles underlying the maintenance of implicit (...) statistical knowledge relevant to language processing, and about possible functional motivations for syntactic priming.

Les années 1930 et 1940 marquent une période de crise pour le libéralisme. Des auteurs aussi divers que Friedrich Hayek, Wilhelm Röpke, Walter Lippmann ou encore Michael Polanyi et Louis Rougier se réunissent lors de deux événements fondateurs, le colloque Walter Lippmann en 1938 et la création de la Société du Mont-Pèlerin en 1947, pour repenser le libéralisme. Cette refonte du projet libéral les pousse à établir un diagnostic relatif à la crise du libéralisme, remontant, pour les auteurs mentionnés, à (...) la Révolution française. Cet article se propose de montrer la cohérence du projet néolibéral à partir de leur diagnostic historique dans cette période de crise. En effet, en critiquant la Révolution française et ses effets comme participant d’un rationalisme néfaste, ayant donné naissance aussi bien au laissez-faire qu’aux divers collectivismes, les néolibéraux reprennent explicitement des concepts des critiques de la révolution, au premier rang desquels Edmund Burke. Le concept de tradition, compris comme recouvrant des règles sociales et juridiques ayant lentement évolué de façon à constituer des dispositifs de coordination permettant nos actions, est ainsi très largement repris et valorisé par les néolibéraux. Nous interprétons ainsi la théorie néolibérale à partir de cette recatégorisation du concept de tradition, et pointons les affinités des positions néolibérales avec le conservatisme philosophique. Ce rapprochement fait apparaître plusieurs tensions conceptuelles entre d’une part un évolutionnisme culturel et d’autre part la défense de valeurs occidentales substantielles. (shrink)

Explanation in terms of gene regulatory networks has become standard practice in evolutionary developmental biology. In this paper, we argue that GRNs fail to provide a robust, mechanistic, and dynamic understanding of the developmental processes underlying the genotype–phenotype map. Explanations based on GRNs are limited by three main problems: the problem of genetic determinism, the problem of correspondence between network structure and function, and the problem of diachronicity, as in the unfolding of causal interactions over time. Overcoming these problems requires (...) dynamic mechanistic explanations, which rely not only on mechanistic decomposition, but also on dynamic modeling to reconstitute the causal chain of events underlying the process of development. We illustrate the power and potential of this type of explanation with a number of biological case studies that integrate empirical investigations with mathematical modeling and analysis. We conclude with general considerations on the relation between mechanism and process in evo-devo. (shrink)

Immunology — though deeply experimental in everyday practice — is also a theoretical discipline. Recent advances in the understanding of innate immunity, how it is triggered and how it shares features that have previously been uniquely ascribed to the adaptive immune system, can contribute to the refinement of the theoretical framework of immunology. In particular, natural killer cells and macrophages are activated by transient modifications, but adapt to long-lasting modifications that occur in the surrounding tissue environment. This process facilitates the (...) maintenance of self-tolerance while permitting efficient immune responses. In this Essay we extend this idea to other components of the immune system and we propose some general principles that lay the foundations for a unifying theory of immunity — the discontinuity theory. According to this theoretical framework, effector immune responses (namely, activated responses that lead to the potential elimination of the target antigen) are induced by an antigenic discontinuity; that is, by the sudden modification of molecular motifs with which immune cells interact.

Written memoranda of conversations, or memcons, provide a near‐contemporaneous record of what was said in conversation, and offer important insights into the activities of high‐profile individuals. We assess the impact of writing a memcon on memory for conversation. Pairs of participants engaged in conversation and were asked to recall the contents of that conversation 1 week later. One participant in each pair memorialized the content of the interaction in a memcon shortly after the conversation. Participants who generated memcons recalled more (...) details of the conversations than participants who did not, but the content of recall was equally and largely accurate for both participants. Remarkably, only 4.7% of the details of the conversation were recalled by both of the partners after a week delay. Contemporaneous note‐taking appears to enhance memory for conversation by increasing the amount of information remembered but not the accuracy of that information. These findings have implications for evaluating the testimony of participants on conversations with major political or legal ramifications. (shrink)

“Erotism and Censorship“ offers an introduction to the history of picture postcards and explores the German censorship until 1930. The specificity of the medium to react to the desires of the clients (mostly male) and to shape them simultaneously is explained in interpretations of examples. A documentary part presents a selection of texts about reproduction technologies. These texts were originally published in journals for collectors of postcards.

When we hear about a transgression, we may consider whether the perpetrator’s individual circumstances make their transgression more understandable or excusable. Mitigating circumstances may reduce the severity of punishment that is deemed appropriate, both intuitively and legally. But importantly, in courts of public opinion and of law, mitigating information is typically presented only after information about a perpetrator’s transgression. We explore whether this sequence influences the force of mitigating evidence. Specifically, in two studies, we examined whether presenting evidence about a (...) perpetrator’s background before or after evidence of their violation influenced how severely U.S. participants punished perpetrators. In Study 1 (N = 132), evidence about the perpetrator’s mitigating circumstances reduced punishment only when it was presented before evidence about the perpetrator’s violation. Study 2 (N = 316) additionally revealed this moderating effect of presentation order across a variety of premeditated and impulsive violations. These findings are consistent with person-centered theories of punishment and with the Story Model of adjudication. (shrink)

Die Schrift bringt den Text einer Vorlesung, die im Wintersemester 1935/36 unter dem Titel »Grundfragen der Metaphysik« an der Universität Freiburg/Br. gehalten wurde.

This research investigated whether perceived situational appropriateness (defined as the degree of fit between product and intended usage situations) is predictive of consumer choices for foods and beverages, on the theoretical premise that intended usage situation acts as a frame of reference in orienting choices. Extant research on the topic, though suggestive of a link, is very limited in scope and almost completely lacking with regards to choice behaviour (as opposed to other aspects such as food acceptability or intake). To (...) address the hypotheses, data collected in a series of 15 experiments ($N= 2731$ consumers in total) -- covering a wide range of product categories and usage situations -- are presented. In all studies, participants evaluated a set of stimuli varying with respect to perceived appropriateness (low to high), and evaluated each stimulus either monadically using a choice likelihood scale or by performing a discrete choice task. Regression analyses from all studies consistently indicated that perceived appropriateness significantly predicted choice response. The results were robust with respect to variation in product category and experimental protocol and, overall, strongly support the notion that appropriateness can provide a simple yet powerful (in some case accounting for over 50\% of variance) predictor of consumer choice. Effect sizes varied substantially: perceived appropriateness explained from a minimum of 3\% to over 65\% of variance in consumer choice, and this variation was linearly related to the degree of product heterogeneity in the product sets. This research also investigated possible moderators of the link between appropriateness and choice, by relating the results to consumers’ product familiarity and involvement. While both traits significantly (and positively) affected choice, they did not interact with appropriateness. Possible explanations for these results, as well as other possible candidate moderators to explore in future research, are highlighted. (shrink)

Christiansen & Chater propose that language comprehenders must immediately compress perceptual data by “chunking” them into higher-level categories. Effective language understanding, however, requires maintaining perceptual information long enough to integrate it with downstream cues. Indeed, recent results suggest comprehenders do this. Although cognitive systems are undoubtedly limited, frameworks that do not take into account the tasks that these systems evolved to solve risk missing important insights.
