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

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)

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)

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: [email protected].

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.

This essay deals with a conspicuous feature of early modern experimental reports: references to multiple repetitions. I examine an episode from the history of research on venomous snakes, the dispute between Francesco Redi and Moyse Charas about the cause of death from viper bites. I identify different kinds of repetitions that are described and specify the various different roles that are attributed to repetitions in experimental reports. I argue that repetition (the successive reproduction of one's own experimental trials) should be (...) distinguished from replication (reproducing other investigators' experiments). At first, replications played hardly any role in the exchange, but references to repetitions were crucial to show that contingencies had been obviated, to support inductive generalizations, and to specify the exact cause of an experimental effect. Notably, it appears that the replication of effects by different experimental means was not part of the repository of methodological notions that Redi and Charas brought to bear on their experiments. Reruns and repetitions with variations (including complementary trials) bore the epistemic weight. -/- . (shrink)

The published HPS paper gives us only an insufficient idea of the project of integrating history and philosophy of science. To understand how the integration may work and to make it even more rewarding, we need to reflect on the very process of constructing theories of the epistemic features of science. My paper develops this claim and considers its implications.

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.

Der österreichische Philosoph Christian von Ehrenfels gilt als "Vater der Gestaltpsychologie". Mit seiner Studie "Über Gestaltqualitäten" legte er die Basis für die Gestaltpsychologie als neuer wissenschaftlicher Disziplin, wirkte aber auch befruchtend auf anderen philosophischen Gebieten. Er verfasste Schriften zu Werttheorie und Ästhetik, Psychologie, Ethik und Erkenntnistheorie und später intensiv zu metaphysischen Themen. Daneben war er auch Dichter und schrieb als leidenschaftlicher Wagnerianer Opernlibretti und andere dramatische Werke, die häufig als Sprachrohr für seine sozial- und sexualreformerischen Ideen dienten. Der Band vereinigt (...) Beiträge, die einleitend der Entwicklung, sowie ontologischen und metaphysischen Aspekten des Gestaltbegriffs gewidmet sind, mit Studien, die die werttheoretischen und sozialphilosophischen Implikationen von Ehrenfels' Philosophie behandeln. Beleuchtet werden weiters die Möglichkeiten und Konsequenzen, die die Einführung des Gestaltbegriffs für Ästhetik und Kunstontologie mit sich bringt. Abgerundet wird der Band durch die kommentierte Erstveröffentlichung von Ehrenfels' Dissertation, die als Vorstufe für die spätere Entwicklung des Gestaltbegriffes anzusehen ist. (shrink)

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)

This paper discusses the claim that science is “messy.” Part I argues first, that a good portion of today’s discussions about messy science is just a portrayal of familiar features of science in new terms. In the paper, I refer to this as “messy science talk.” Second, Part I draws out rhetorical functions of messy science talk, namely the denigration of science in the popular media and the celebration of the maverick. Part II identifies one way in which it is (...) enlightening to think about mess in current science, namely in reference to the problems that scientists need to address. It also shows that we do not need an entirely new conceptual inventory to analyze these problems. “Mess” and “wicked problems” were a theme in operations research and theories of social planning in the 1970s. These older analyses can illuminate important characteristics of today’s scientific problems. Wicked problems cut across different disciplines, engage different stakeholders (including non-scientists), are fluid, and cannot even be clearly formulated. They are urgent and need to be addressed before sufficient evidence is in. (shrink)

This paper discusses two methodological notions, the concepts Gegenprobe (countercheck) and Gegenversuch (counter-trial), which were widely applied, discussed, relied upon, and defended in German-language writings about empirical inquiry. In the decades around 1800, they were common in physiology; medicine; agriculture; chemistry; various technologies, such as printing, metallurgy, and mining; accounting; and legal and political argumentation. The ubiquity of those concepts signals a broad concern with securing empirical findings and empirical knowledge. Gegenproben and Gegenversuche – the terms as well as the (...) practices – are evidence for the close connection among explicitly knowledge-seeking endeavors and crafts and technologies. Physiological experiments, chemical analyses, agricultural or vaccination trials were indebted to applied and practical procedures of making and assaying. What united these different fields was the fact that the problems that had to be solved were very complex yet at the same time of immediate relevance to everyday lives (like diseases or crops) or highly controversial (like vital forces or spontaneous generation). We know that late eighteenth-century and early nineteenth-century practices of inquiry were firmly embedded in applied, technical contexts; this essay shows that methodological notions were anchored in applied, technical contexts as well.

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)

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 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 concerned with the epistemic roles of error in scientific practice. Usually, error is regarded as something negative, as an impediment or obstacle for the advancement of science. However, we also frequently say that we are learning from error. This common expression suggests that the role of error is not—at least not always—negative but that errors can make a fruitful contribution to the scientific enterprise. My paper explores the latter possibility. Can errors play an epistemically productive role in (...) scientific research? The paper begins with a review of several twentieth-century approaches to error and the various agendas behind them. It is shown that only very few scholars have considered whether errors can be productive. The main part of the paper examines a concrete debate in early nineteenth-century microscopy and analyses how the microscopists coped with the problem of error. Drawing on this material, the article offers some terminological clarifications of the common notion ‘learning from error’. The conclusion argues that error can indeed play epistemically productive roles in scientific practice.Keywords: Error; Nineteenth-century microscopic anatomy. (shrink)

ABSTRACT This paper discusses the place and significance of comparative trials in German agricultural writings around 1800. In the second half of the eighteenth century, practitioners of agriculture began to discuss the role and design of agricultural trials. The notion of comparative experimentation played a significant role in these discussions, but it could mean quite different things: comparative assessment of treatments in terms of yield, cost-effectiveness, and adequacy for an intended purpose; comparative input variations to explore the multitude of effects (...) of certain causes; and the comparison of something treated with something untreated, to establish the effects of a treatment more securely. Some German agriculturists developed their methodologies explicitly in contrast to the laboratory experiment, as they conceived it. Others invoked systematic variations and practices of quality control that they imported from technological contexts. Yet others drew on philosophical discussions of cause–effect relations. (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 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 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)
