Marsilio Ficino, Protegé Cosimos, Pieros und Lorenzos von Medici, gilt als Zentralgestalt des italienischen Renaissance-Platonismus. Mit den Übersetzungen der Dialoge Platons, der Schriften Plotins und des Corpus Hermeticum sowie durch eine theoretische Verknüpfung von antiker Philosophie mit christlicher Religion übte er einen unübersehbar grossen Einfluss auf die europäische Wissenschafts- und Geistesgeschichte aus. Im Zentrum seines Theorie-Gebäudes steht ein komplexes Konzept von Magie, dessen Konstruktion bis heute erforscht wird. Es hat dem Band den Titel gegeben, dessen Themen sich Ficinos intellektuellem Horizont (...) entsprechend jedoch in eine Vielzahl weiterer Aspekte ausdifferenzieren. Diese literarisch-künstlerischen, literaturwissenschaftlichen, wissenschaftshistorischen und philosophisch-theologischen Implikationen von Ficinos Schriften werden paradigmatisch und vergleichend behandelt.

This essay offers some reflections on the recent history of the disputes about the relation between history and philosophy of science (HPS) and the merits and prospects of HPS as an intellectual endeavor. As everyone knows, the issue was hotly debated in the 1960s and 1970s. That was the hey-day of the slogan "history without philosophy of science is blind, philosophy without history of science is empty" as well as of the many variations on the theme of HPS as a (...) "marriage of convenience," "intimate relation," or "marriage for the sake of reason." There was a flurry of interest in the early 1990s, as evidenced by sections in the 1992 and 1994 issues of PSA, entitled: "Do the History of Science and the Philosophy of .. (shrink)

Depression is a disorder of impaired emotion regulation. Consequently, examining individual differences in the habitual use of emotion-regulation strategies has considerable potential to inform models of this debilitating disorder. The aim of the current study was to identify cognitive processes that may be associated with the use of emotion-regulation strategies and to elucidate their relation to depression. Depression has been found to be associated with difficulties in cognitive control and, more specifically, with difficulties inhibiting the processing of negative material. We (...) used a negative affective priming task to assess the relations among inhibition and individual differences in the habitual use of rumination, reappraisal, and expressive suppression in clinically depressed, formerly depressed, and never-depressed participants. We found that depressed participants exhibited the predicted lack of inhibition when processing negative material. Moreover, within the group of depressed participants, reduced inhibition of negative material was associated with greater rumination. Across the entire sample, reduced inhibition of negative material was related to less use of reappraisal and more use of expressive suppression. Finally, within the formerly depressed group, less use of reappraisal, more use of rumination, and greater expressive suppression were related to higher levels of depressive symptoms. These findings suggest that individual differences in the use of emotion-regulation strategies play an important role in depression, and that deficits in cognitive control are related to the use of maladaptive emotion-regulation strategies in this disorder.

Comprendre les pratiques d'économie solidaire au regard de la notion d'espace public suppose de mettre en évidence les tensions que ces pratiques mettent en oeuvre : à partir des solidarités et de réciprocités éprouvées dans les « mondes vécus » et leurs espaces culturels, ces pratiques combinent des ressources du marché, de l'économie publique et de la réciprocité dans la visée d'une économie juste répondant à une délibération démocratique entre les acteurs concernés. Une telle perspective oblige à affronter une conception (...) pluraliste et agonistique des espaces publics où sont en tension l'agir stratégique des acteurs, leurs « mondes vécus », sources d'identités et conditions de l'autonomisation du sens de l'action, et des espaces d'argumentation et de débats où s'élabore un bien commun reconnu comme juste. Ces tensions doivent être aussi comprises dans leur ouverture conflictuelle aux espaces politico-administratifs institués et aux espaces d'influence d'acteurs poursuivant leurs intérêts particuliers dans le territoire local. Mais, sous couvert de partenariat et de coopération entre les acteurs, les nouvelles politiques locales entérinent les rapports inégalitaires entre les acteurs et conduisent la société civile à taire ses dissensions sous peine de voir se tarir leur légitimité politique et leurs financements publics.In order to evaluate the practices of civil and solidarity-based economy, it is necessary to be aware of the tensions that they generate. They combine market resources, public support, and ideas of reciprocity, aiming to create fair economies and to democratically mobilize those concerned. Such a perspective requires a pluralist and conflictual conception of public spheres. In this perspective, tensions become important between strategic action and identities. These tensions must also be understood as they arise in political and administrative arenas and in the context of local actors motivated by self-interest in the local community. Although there appears to be a partnership between all the actors concerned, new policies directed towards local communities confirm the existence of social inequalities between the various stakeholders. The result is often that civil society keeps silent about these tensions lest their political influence and sources of public finance should dry up. (shrink)

This article identifies a fundamental distinction in scientific practice: the mismatch between what scientists do and what they state they did when they communicate their findings in their publications. The insight that such a mismatch exists is not new. It was already implied in Hans Reichenbach's distinction between the contexts of discovery and justification, and it is taken for granted across the board in philosophy of science and science studies. But while there is general agreement that the mismatch exists, the (...) epistemological implications of that mismatch are not at all clear. Philosophers, historians, and sociologists of different stripes have expressed widely different views about how one should understand and interpret the relation between what scientists do and what they state they did. This article surveys a number of approaches to the mismatch. Based on this survey, I offer an assessment of the epistemological significance of the mismatch and identify the major meta-epistemological challenges that it poses for the analysis of scientific practice. *Received May 2007; revised April 2008. †To contact the author, please write to: Department of History and Philosophy of Science, 1011 East Third Street, Goodbody Hall 130, Indiana University, Bloomington, IN 47405; e-mail: jschicko@indiana.edu.

The ability to process center‐embedded structures has been claimed to represent a core function of the language faculty. Recently, several studies have investigated the learning of center‐embedded dependencies in artificial grammar settings. Yet some of the results seem to question the learnability of these structures in artificial grammar tasks. Here, we tested under which exposure conditions learning of center‐embedded structures in an artificial grammar is possible. We used naturally spoken syllable sequences and varied the presence of prosodic cues. The results (...) suggest that mere distributional information does not suffice for successful learning. Prosodic cues marking the boundaries of the major relevant units, however, can lead to learning success. Thus, our data are consistent with the hypothesis that center‐embedded syntactic structures can be learned in artificial grammar tasks if language‐like acoustic cues are provided. (shrink)

Mueller et al. discuss the role of acoustic cues in detecting language structure more generally. Across languages, there are clear links between acoustic cues and syntactic structure. They show that AGL experiments implementing analogous links demonstrate that prosodic cues, as well as various auditory biases, facilitate the learning of structural rules. Some of these biases, e.g. for auditory grouping, are also present in other species.

In Extragalactic Reality: The Case of Gravitational Lensing Hacking resumes the discussion of scientific realism from the last chapter of Representing and Intervening. Since the criterion of manipulability cannot be applied to astronomical objects, experimental entity realism seems to be restricted to terrestrial entities. In fact, Hacking explicitly argues against astronomical realism. The case at issue is the existence of gravitational lenses. In this paper, I question Hacking 's chief witness for astronomical antirealism: the gravitational lens system “0957+ 561”. It (...) will be shown that Hacking 's argumentation is misleading. Discussing astronomical realism as theory realism, Hacking focuses on the question of how to infer the existence of gravitational lenses from the truth of gravitational lens theory. But neither the reconstruction of gravitational lensing in terms of inference to the best explanation nor the argument of underdetermination are tenable under closer inspection. My thesis is that a realist account of gravitational lensing can be given by relying on observation, causal capacities and home truths. (shrink)

Sustained negative affect is a hallmark feature of depressive episodes. The ability to regulate emotional responses to negative events may therefore play a critical role in our understanding of this debilitating disorder. Individual differences in cognitive processes such as attention, memory, and interpretation may underlie difficulties in emotion regulation and numerous studies have identified cognitive biases and deficits that characterise depressed people. Few studies, however, have explicitly linked these biases to the difficulties in emotion regulation that are associated with depression. (...) In this paper we discuss relations among cognitive processes and emotion regulation and review the depression literature to identify cognitive biases and deficits that may underlie maladaptive responses to negative events and mood states. Our review suggests that difficulties in the disengagement from negative material, memory biases, and deficits in cognitive control are frequently observed in depressive disorders and may be associated with the use of maladaptive emotion regulation strategies, such as rumination. These biases may also be related to difficulties implementing strategies that are effective for non-depressed people, such as recall of mood-incongruent material and reappraisal. Our review also suggests, however, that empirical studies linking cognitive biases and emotion regulation in depression are still largely missing and would present an important goal for future research in this area.

While painted wooden icons of the Nursing Virgin were relatively common in fifteenth-century Ethiopia, only one miniature of the motif of the time has come to light. This image, bound into a later manuscript of the Miracles of Mary, is painted in a decidedly abstract style, comparable to other representations of the Virgin in fifteenth-century Ethiopian book illustration. Relying on Peirce’s distinction between index and icon, this article considers how such abstract representations might have been meant to evoke the divine (...) presence of Mary as a spiritual trace of the artist’s and the audience’s devotional practices, rather than as a potentially miracle-working depiction of her corporeal presence based on figural likeness, as was the case with painted wooden panels. Incorporating references to Ethiopian and Western theorists of modernity, the essay further proposes to view the multiple and interlocking mirror effects in book art as instances of second-order observation, in which, for example, the Virgin sees herself depicted in a book of her miracles, the compilation of which she commissioned and aided; the scribe and artist is featured in one of the miracles he himself is writing and illustrating; and the donor is depicted gazing at the viewer. Whether enabling skeptical distance or a more fully immersive spiritual experience undisturbed by attempts to capture corporeal likeness, or both, this essay proposes to analyze the politics and theology of abstraction in fifteenth-century Ethiopian book art by centering on a rare depiction of the Nursing Virgin.

This paper examines how scientists conceptualize their research methodologies. Do scientists raise concerns about vague criteria and genuine uncertainties in experimental practice? If so, what sorts of issues do they identify as problematic? Do scientists acknowledge the presence of value judgments in scientific research, and do they reflect on the relation between epistemic and non-epistemic criteria for decisionmaking? We present findings from an analysis of qualitative interviews with 63 scientific researchers who talk about their views on good research practice. We (...) argue that analysts of science should care about scientists’ conceptualizations of the criteria and of the practical judgments that scientific inquiry involves. While scientists’ accounts of their own research methodologies alone do not give us a full picture of how science really works, they can point us to areas of concern. They can inspire and direct philosophical reflections about how science works. Throughout the interviews, the participating researchers provided specific examples from their own research contexts as illustrations of their methodological points. These examples reveal that scientists often struggle to evaluate the quality of their data, to figure out whether the available evidence confirms their hypothesis, whether a replication was successful, or to what extent they can rely on peer-reviewed papers. General ideas about good research methods do not directly translate into specific evaluation criteria or strategies that can guide research and help validate empirical data. (shrink)

This volume thus clears the ground for the productive and fruitful integration of these new developments into philosophy of science.

This paper addresses the question to what extent locative/situational proforms such as German da, Dutch er/daar and English there are to be considered expletives. It considers the main contexts of use for all three languages, their appearance as modifiers, in existential constructions and in other potential expletive positions, such as Spec,TP and Spec,CP, as well as the uses as correlates to clauses. The paper argues that all three locative-based proforms act as situation proforms, though they show differences in their syntax. (...) English there is restricted to locative modifier uses and can only appear as situation proform in the existential constructions; German da appears in existential contexts, and it also has a situation proform use in modifier position. Dutch er has the broadest distribution ranging from existential to Spec,TP and — resulting from that — Spec,CP positions. Finally, Dutch er and German da occur as correlate with prepositional object clauses. The paper offers a comparative analysis in which the difference between those elements result from different base positions and other general differences between the languages. (shrink)

Murayama and Jach claim that current motivational constructs do not specify causal processes (black-box problem) and that mental computational processes solve this problem. We argue, process-focused research requires theoretical frameworks addressing situational variations, individual differences, and their interaction. Classic achievement motivation theory provides comprehensive models with empirically measurable process-related constructs and predictions. Recent developments build on this, addressing motivation, action, and their socio-cultural and lifespan context. Theory-free mental computational processes cannot do any of that.

: This paper is concerned with the claim that epistemic terms and categories are historical entities. The starting point is the observation that recent attempts at historical studies of epistemic terms fail to bridge the gap between history and philosophy proper. I examine whether, and how, it is possible to forge a closer link between historical and philosophical aspects of conceptual analysis. The paper explores possible links by analyzing aspects of the concept of error. A "pragmatic" and a "mentalist" notion (...) of error are identified in current philosophical studies of error: according to the latter, errors can be ascribed only to mental operations, according to the former, errors can also be ascribed to things and processes. The paper then draws on historical accounts of optical instruments to highlight certain presuppositions and implications of these two uses of the term. Contextual features and trans-contextual structures of the notion of error are distinguished. In conclusion, I argue that an intimate link between history and philosophy of science can be forged by an analysis ofthe development of conceptual arrangements which allows for trans- contextual structural aspects while drawing attention to the contextual epistemological and scientific conditions of their re-arrangement.

This article presents a new framework for the analysis of experimental control. The framework highlights different functions for experimental controls in the realization of an experiment: experimental controls that serve as tests and experimental controls that serve as probes. The approach to experimental control proposed here can illuminate the constitutive role of controls in knowledge production, and it sheds new light on the notion of exploratory experimentation. It also clarifies what can and what cannot be expected from reviewers of scientific (...) journal articles giving feedback on experimental controls. (shrink)

Summary The first systematic studies on the velocity of chemical reactions (now called reaction rates) were published in the 1850s and 1860s. Inquiring about the course of chemical change, their authors established empirical equations on the basis of their measurement results. But these laws, which represented reaction velocities as proportional to the actual concentration of the reagents, could not be given a physical foundation. The chemists themselves regarded their propositions as mere ad hoc hypotheses. In 1867 Leopold Pfaundler formulated a (...) qualitative theory of chemical processes based on Clausius's version of the kinetic gas theory (and more specifically on his theory of evaporation), and on Saint-Claire Deville's investigations of dissociation processes. Pfaundler's theory was based on farreaching analogies: between evaporation and dissociation; between the gaseous state and the activated state; and between evaporation- and chemical-equilibrium. Four points of Pfaundler's theory must be regarded as essential: (1) the reduction of chemical change to randomly occurring molecular collisions, only showing regularities in great numbers according to the laws of probability; (2) the idea that molecules are in different states of internal and external motion, which determines whether a collision results in a reaction; (3) the view of the reaction step as a transition from internal to external motion and vice versa; and (4) the introduction of a new molecular-kinetic definition of chemical affinity as the maximum of internal motion. With these assumptions, Pfaundler provided the empirical rate equations with a new statistical interpretation and a physical Justification. (shrink)

Risk assessment is an evidence-based analytical framework used to evaluate research findings related to environmental and public health decision-making. Different routines have been adopted for assessing the potential risks posed by substances and products to human health. In general, the traditional paradigm is a hazard-driven approach, based on a monocausal toxicological perspective. Questions have been raised about the applicability of the general chemical risk assessment approach in the specific case of nanomaterials. Most scientists and stakeholders assume that the current standard (...) methods are in principle suitable, but point out that experimental aspects and practical guidelines need specific adaptations. Beyond this laboratory level, risk assessment of nanomaterials also faces a number of substantive and procedural limitations, which are intrinsically attributed to the general orthodoxy of the risk assessment concept. Moreover, the developed formalism used to organize scientific knowledge is closely interlinked with the underlying governance design and the mode of interaction between the two spheres of ‘science’ and ‘decisions’. This contribution will provide a closer look at the evolution of different institutional settings for risk assessment in the context of decision-making. Improved risk governance frameworks with different narratives, process designs and procedural elements will be compared. The question of a general principle of enhanced organization of risk assessment will be discussed taking account of the barriers of substantive and procedural limitations in the special case of nanomaterials.

This article sets out to provide a conceptual contribution to theoretical and empirical work on the level of media repertoires. We will first discuss theoretical approaches which allow for an explanation of media repertoires and relate them to the most prominent approaches to selective audience behavior. Secondly, in order to empirically analyze media repertoires we propose a combination of secondary analyses of existing surveys on media use and qualitative studies on the internal ‘architecture’ of these repertoires and their practical meaning (...) in the user's everyday life. These proposals for secondary analyses are illustrated by two examples based on different data sets and referring to different levels of analysis. (shrink)

This essay is a contribution to the history of methodological thought. I focus on key methodological criteria for successful experimentation, replication and multiple determinations of empirical evidence. Drawing on reports of experiments with viper venom from the late seventeenth and late eighteenth centuries, as well as on present-day methodological thought I examine whether past experimenters regarded repetition, replication, and multiple determinations as criteria for validity; what exactly they meant by this; what they hoped to gain by repeating, varying, triangulating, and (...) replicating; and how relevant these criteria were for them. I also consider if this analysis has implications for current philosophical work on the methodology of experimental practice. (shrink)

This article examines a metaphilosophical issue, namely existing disagreements in philosophy of science about the significance of using multiple means of determination in scientific practice. We argue that this disagreement can, in part, be resolved by separating different questions that can be asked about the use of multiple means of determination, including the following: what can be concluded from the convergence of data or the convergence of claims about phenomena? Are the conclusions drawn from the convergence of data and of (...) statements about phenomena of special importance to the debate about realism and antirealism? Do inferences based on multiple means of determination have stronger epistemic force than inferences that are secured in other ways? Is the epistemic goal of deploying multiple means of determination well entrenched within the scientific community? Most of these questions can be discussed both in a formal and in an empirical perspective. If the differences in perspective are taken into account, some disagreements can be easily resolved. In part, however, the disagreements reflect historiographical challenges that are very difficult, if not impossible to meet. (shrink)

Today, Larry Laudan is known predominantly for his work on the pessimistic metainduction and for his discussion of science and values. This essay examines a less familiar part of Laudan’s work, his typology of historical methodologies from the late 1970s. My aim is to elucidate Laudan’s typology and to examine one of the types in more depth, namely, the “pragmatic, symbiotic” model of historical methodology. Laudan expounded the model in the essays that eventually became his 1981 book Science and Hypothesis. (...) Laudan himself characterized this approach to methodology as “history of philosophy of science” and described a number of historiographical guidelines for this history. Several of Laudan’s questions about past scientific methodologies are still worth pursuing, although—and in part because—the concept of scientific methodology changed dramatically as philosophers turned to experimentation in the late twentieth century. Moreover, the study of Laudan’s work in the historical context in which it was devised can shed light on the historical turn in philosophy of science. (shrink)

: This article analyzes the transformation of epistemological and methodological discourses in German microscopy. It is argued that the expansion of microscopy in the early decades of the nineteenth century was pivotal for the emergence of intricate methodologies that characterized the instruments and methods of microscopy in new ways. Close examination of these means of investigation showed them to be intrinsically imperfect. The flaws of the instrument, the faults of the observer's eyes and the obstructive power of the objects of (...) investigation actions came to be crucial issues in epistemological and methodological debates. It became clear that the particulars of the research arrangement not only limited the range of possible microscopical observations but would always impede and interfere with the results: Perfect working conditions could never be achieved.
