Enactment of mandated pre-procedure disclosures in abortion and assisted reproductive technology services has swelled in recent years. Calls to equally regard these mandates as neutral tools in furtherance of patient protection fail to acknowledge key substantive and structural differences in these reproduction-affecting mandates. While ART mandates permit physicians to use their medical judgment to protect presumptively vulnerable egg donors and gestational carriers, abortion disclosures impart scientifically suspect messaging aimed at dissuading women from pursuing pregnancy termination. These and other distinctions counsel (...) in favor of regarding and analyzing abortion and ART mandated disclosures as separate and distinguishable informed consent tools. (shrink)

This paper examines the controversy that followed the 1987 publication of Joseph Greenberg's book, Language in the Americas, attending to the role of language and linguistic research within overlapping disciplinary traditions. With this text, Greenberg presented a macro‐level tripartite classification that opposed then dominant fine‐grained analyses recognizing anywhere from 150 to 200 distinct language families. His proposal was the subject of a landmark conference, examining strengths and weaknesses, the unpublished proceedings of which are presented here for the first time. For (...) specialists in the anthropological and comparative‐historical study of Indigenous American languages, Greenberg's intervention highlighted the tension between language, conceived as an abstract object of study, and languages, understood to be carriers of specific cultural knowledge. For physical anthropologists and archaeologists, his theory was initially fortuitous on programmatic, substantive, and methodological grounds. The essay will show how interdisciplinary appeals were figured by supporters as a virtue, and by critics as a vice. The essay further highlights ethical reasons for integrating historical narratives of science and the humanities. (shrink)

Over the past decade, Canadian media coverage of street sex work has steadily increased. The majority of this interest pertains to graphic violence against street sex workers, most notably from Vancouver, British Columbia. In this article, the authors analyze newspaper coverage that appeared in western Canadian publications between 2006 and 2009. In theorizing the violence both depicted and perpetrated by newspapers, the authors propose an analytic framework capable of attending to the process of othering in all of its complexity. To (...) this end, the authors supplement a Foucauldian analysis of abjection by considering the work of Judith Butler along with Julia Kristeva's conceptualization of abjection. Using excerpts from western Canadian newspapers, the authors illustrate how the media's discursive practices function as triggers for the process of cultural abjection by inscribing street sex workers with images of defilement. The authors argue that newspaper coverage of street sex workers reinforces the inviolability of normalized life by constantly reiterating the horror reserved for abjected bodies. (shrink)

. Science at the interface with society is regarded with mistrust among parts of the public. Scientific judgments on matters of practical concern are not infrequently suspected of being incompetent and biased. I discuss two proposals for remedying this deficiency. The first aims at strengthening the independence of science and suggests increasing the distance to political and economic powers. The drawback is that this runs the risk of locking science in an academic ivory tower. The second proposal favors “counter-politicization” in (...) that research is strongly focused on projects “in the public interest,” that is, on projects whose expected results will benefit all those concerned by these results. The disadvantage is that the future use of research findings cannot be delineated reliably in advance. I argue that the underlying problem is the perceived lack of relevance and reliability and that pluralism is an important step toward its solution. Pluralism serves to stimulate a more inclusive research agenda and strengthens the well-testedness of scientific approaches. However, pluralism also prevents the emergence of clear-cut practical suggestions. Accordingly, pluralism is part of the solution to the credibility crisis of science, but also part of the problem. In order for science to be suitable as a guide for practice, the leeway of scientific options needs to be narrowed – in spite of uncertainty in epistemic respect. This reduction can be achieved by appeal to criteria that do not focus on the epistemic credentials of the suggestions but on their appropriateness in practical respect. (shrink)

How should we live? What do we owe to other people? In Goodness and Advice, the eminent philosopher Judith Jarvis Thomson explores how we should go about answering such fundamental questions. In doing so, she makes major advances in moral philosophy, pointing to some deep problems for influential moral theories and describing the structure of a new and much more promising theory. Thomson begins by lamenting the prevalence of the idea that there is an unbridgeable gap between fact and (...) value--that to say something is good, for example, is not to state a fact, but to do something more like expressing an attitude or feeling. She sets out to challenge this view, first by assessing the apparently powerful claims of Consequentialism. Thomson makes the striking argument that this familiar theory must ultimately fail because its basic requirement--that people should act to bring about the "most good"--is meaningless. It rests on an incoherent conception of goodness, and supplies, not mistaken advice, but no advice at all. Thomson then outlines the theory that she thinks we should opt for instead. This theory says that no acts are, simply, good: an act can at most be good in one or another way--as, for example, good for Smith or for Jones. What we ought to do is, most importantly, to avoid injustice; and whether an act is unjust is a function both of the rights of those affected, including the agent, and of how good or bad the act is for them. The book, which originated in the Tanner lectures that Thomson delivered at Princeton University's Center for Human Values in 1999, includes two chapters by Thomson ("Goodness" and "Advice"), provocative comments by four prominent scholars--Martha Nussbaum, Jerome Schneewind, Philip Fisher, and Barbara Herrnstein Smith--and replies by Thomson to those comments.

Agnotology concerns the creation and preservation of confusion and ignorance. Certain positions are advocated in science in order to promote sociopolitical interests with the result of launching mock controversies or epistemically unjustified dissent. I propose to identify agnotological ploys by the discrepancy between the conclusions suggested by the design of a study and the conclusions actually drawn or intimated. This mechanism of “false advertising” serves to implement agnotological endeavors and helps identify them without having to invoke the intentions of the (...) relevant agents. I discuss three agnotological cases, i.e., studies on bisphenol A, Bt-maize/Roundup, and Oslo’s airport Gardermoen. Pinpointing agnotological endeavors is a means for weeding out approaches that look fitting at first glance, but are blatantly inappropriate, in fact. (shrink)

In my contribution to this volume, I (BHS) comment on on the stultifying rhetoric of contemporary analytic moral theory as illustrated in Judith Jarvis Thomson's Tanner Lectures, with particular reference to Thomson's anxieties about the moral relativism exhibited by college freshman and to her efforts--quite strained, in my view, and inevitably unsuccessful--to demonstrate the existence of objective judgments in matters of morality and taste .

I address options for providing scientific policy advice and explore the relation between scientific knowledge and political, economic and moral values. I argue that such nonepistemic values are essential for establishing the significance of questions and the relevance of evidence, while, on the other hand, such social choices are the prerogative of society. This tension can be resolved by recognizing social values and identifying them as separate premises or as commissions while withholding commitment to them, and by elaborating a plurality (...) of policy packages that envisage the implementation of different social goals. There are limits to upholding the value-free ideal in scientific research. But by following the mentioned strategy, science can give useful policy advice by leaving the value-free ideal largely intact. Such scientific restraint avoids the risk of appearing to illegitimately impose values on the public and could make the advice given more trustworthy. (shrink)

One of the arguments advanced in favor of scientific realism is the 'miracle argument'. It says that for the anti-realist the predictive success of science appears as an utter miracle. This argument indeed has some prima facie plausibility, provided that it is sharpened by construing "predictive success" as prediction of previously unknown laws and the occurrence of a consilience of inductions. Still, the history of science teaches us that it is possible to arrive at predictive success in this sense by (...) employing radically non-referring theoretical mechanisms. The 'miracle argument' is thus unsound. Rather, the capacity of a theory to generate predictive success can be traced back to its "classificativity correspondence.". (shrink)

My intention is to cast light on the characteristics of epistemic or fundamental research (in contrast to application-oriented research). I contrast a Baconian notion of objectivity, expressing a correspondence of the views of scientists to the facts, with a pluralist notion, involving a critical debate between conflicting approaches. These conflicts include substantive hypotheses or theories but extend to values as well. I claim that a plurality of epistemic values serves to accomplish a non-Baconian form of objectivity that is apt to (...) preserve most of the intuitions tied to the objectivity of science. For instance, pluralism is the only way to cope with the challenge of preference bias. Furthermore, the plurality of epistemic values cannot be substantially reduced by exploring the empirical success of scientific theories distinguished in light of particular such values. However, in addition to pluralism at the level of theories and value-commitments alike, scientific research is also characterized by a joint striving for consensus which I trace back to a shared epistemic attitude. This attitude manifests itself, e.g., in the willingness of scientists to subject their claims to empirical scrutiny and to respect rational argument. This shared epistemic attitude is embodied in rules adopted by the scientific community concerning general principles of dealing with knowledge claims. My contention is that pluralism and consensus formation can be brought into harmony by placing them at different levels of consideration: at the level of scientific reasoning and at the level of social conventions regarding how to deal with claims put forward within the scientific community.

Fake research produces results that are invalid from the start. I take such research to be characterised by three jointly sufficient features. It is severely methodologically defective, and the relevant defects support certain nonepistemic (social, political, economic) interests and objectives, while the relevant objectives typically concern the interference with attempts at political regulation. I deal with two kinds of claimed fake research. One is agnotological ploys in which scientific dissent is created by interested parties from industry or politics in order (...) to support their own partisan goals. Another one is the populist antiscience movement that suspects fake research in the scientific mainstream. I suggest three remedies to reduce or eliminate the impact of fake research: disclosing fallacies, improving the understanding of scientific methods, and distinguishing more clearly between science and politics in political decision-making.

Responsible research and innovation features the dialog of science “with society,” and research performed “for society,” i.e., for the benefit of the people. I focus on this latter, outcome-oriented notion of RRI and discuss two kinds of problems. The first one concerns options to anticipate the future course of science and technology. Such foresight knowledge seems necessary for subjecting research to demands of social and moral responsibility. However, predicting science and technology is widely considered impossible. The second problem concerns moral (...) evaluation. The benefit or harm produced by certain research and innovation achievements is often hard to estimate. Against this background of uncertainty in factual and moral assessment, I explore opportunities left for RRI. First, RRI should contribute to maintaining a wide range of approaches. Second, judgments about RRI should draw on zones of convergence among the variety of research approaches pursued. Third, decisions about implementing a technology should be revisable. Fourth, the more specific inclusion of demands from society should be reserved to technology development. Fifth, in many respects, the social compatibility of a new technology is due rather to the social context than the inherent features of the product. Favorable circumstances are transparency, representation of all relevant parties, and procedural fairness. As a result, some of the benefits and detriments of research and innovation can be identified without detailed knowledge of future findings. (shrink)

Historical Epistemology: On the Diversity and Change of Epistemic Values in Science. Historical epistemology involves the claim that the system of scientific knowledge is not determined by the observations but is also subject to epistemic requirements that may change in the historical process of doing research. As a result, the system of knowledge is path‐dependent in that its shape is contingent on epistemic choices made at certain historical points. I attempt to elaborate this approach by drawing attention to the double (...) role of epistemic values. First, such values create relations of significance and thereby contribute to directing research into certain avenues. Second, they are also important in the process of confirmation in that they entail that certain forms of agreement with the facts are superior and preferable to other such forms. Some epistemic orientations and reorientations can be reconstructed as arising from an interaction with nature, but others are based on commitments to the kind of knowledge we appreciate. The epistemic authority of science is created in large measure by rules of the scientific community that express how to deal with knowledge claims. (shrink)

It is argued that psychological explanations involve psychological generalizations that exhibit the same features as laws of physics. On the basis of the “systematic theory of lawhood”, characteristic features of laws of nature are elaborated. Investigating some examples of explanations taken from cognitive psychology shows that these features can also be identified in psychological generalizations. Particular attention is devoted to the notion of “ccteris‐paribus laws”. It is argued that laws of psychology are indeed ceteris‐paribus laws. However, this feature does not (...) distinguish them from the laws of physics, because such laws are found in physics as well. Moreover, the laws invoked in psychological explanations are genuine laws of psychology; they are not laws of other disciplines that are brought to bear on psychological problems. The conclusion is that if there are laws of physics then laws of psychology exist as well. (shrink)

Duhem—Quine underdetermination plays a constructive role in epistemology by pinpointing the impact of non-empirical virtues or cognitive values on theory choice. Underdetermination thus contributes to illuminating the nature of scientific rationality. Scientists prefer and accept one account among empirical equivalent alternatives. The non-empirical virtues operating in science are laid open in such theory choice decisions. The latter act as an epistemological test tube in making explicit commitments to how scientific knowledge should be like.

The aim of this paper is to discuss the relation between the observation basis and the theoretical principles of General Relativity. More specifically, this relation is analyzed with respect to constructive axiomatizations of the observation basis of space-time theories, on the one hand, and in attempts to complete them, on the other. The two approaches exclude one another so that a choice between them is necessary. I argue that the completeness approach is preferable for methodological reasons.

In their self-understanding, expert committees solely draw on scientific knowledge to provide policy advice. However, we try to show, first, on the basis of material related to the German Radiation Protection Commission that much of their work consists in active model building. Second, expert advice is judged by criteria that diverge from standards used for judging epistemic research. In particular, the commitment to generality or universality is replaced by the criterion of specificity, and the value of precision gives way to (...) epistemic robustness. Third, non-epistemic considerations are included in the reasoning—albeit hesitantly. Manageability and social robustness, understood as compatibility with widespread value attitudes in society, affect the content of the recommendations. (shrink)

This book puts forward a new role for mathematics in the natural sciences. In the traditional understanding, a strong viewpoint is advocated, on the one hand, according to which mathematics is used for truthfully expressing laws of nature and thus for rendering the rational structure of the world. In a weaker understanding, many deny that these fundamental laws are of an essentially mathematical character, and suggest that mathematics is merely a convenient tool for systematizing observational knowledge. The position developed in (...) this volume combines features of both the strong and the weak viewpoint. In accordance with the former, mathematics is assigned an active and even shaping role in the sciences, but at the same time, employing mathematics as a tool is taken to be independent from the possible mathematical structure of the objects under consideration. Hence the tool perspective is contextual rather than ontological. Furthermore, tool-use has to respect conditions like suitability, efficacy, optimality, and others. There is a spectrum of means that will normally differ in how well they serve particular purposes. The tool perspective underlines the inevitably provisional validity of mathematics: any tool can be adjusted, improved, or lose its adequacy upon changing practical conditions. (shrink)

Earlier in this century, many philosophers of science (for example, Rudolf Carnap) drew a fairly sharp distinction between theory and observation, between theoretical terms like 'mass' and 'electron', and observation terms like 'measures three meters in length' and 'is _2° Celsius'. By simply looking at our instruments we can ascertain what numbers our measurements yield. Creatures like mass are different: we determine mass by calculation; we never directly observe a mass. Nor an electron: this term is introduced in order to (...) explain what we observe. This (once standard) distinction between theory and observation was eventually found to be wanting. First, if the distinction holds, it is difficult to see what can characterize the relationship between theory :md observation. How can theoretical terms explain that which is itself in no way theorized? The second point leads out of the first: are not the instruments that provide us with observational material themselves creatures of theory? Is it really possible to have an observation language that is entirely barren of theory? The theory-Iadenness of observation languages is now an accept ed feature of the logic of science. Many regard such dependence of observation on theory as a virtue. If our instruments of observation do not derive their meaning from theories, whence comes that meaning? Surely - in science - we have nothing else but theories to tell us what to try to observe. (shrink)

The philosophical treatment of space and time has had a long history. This continuing interest stems not least from the fact that space and time form the basis of movement. Space-time philosophy encompasses a wide range of subjects, many of which, on first inspection, do not seem to have anything to do with space and time. Space-time philosophy is a matter of causality and probability, the Big Bang and Heat Death. It is a matter of the origins of each term (...) s meaning and the inability to experience space-time theory first hand. It is a matter of Achilles and the turtle, as well as, Maxwell s demon. In dealing with space-time, one does not deal solely with space and time. ". (shrink)

I attempt a reconstruction of Kant’s version of the causal theory of time that makes it appear coherent. Two problems are at issue. The first concerns Kant’s reference to reciprocal causal influence for characterizing simultaneity. This approach is criticized by pointing out that Kant’s procedure involves simultaneous counterdirected processes—which seems to run into circularity. The problem can be defused by drawing on instantaneous processes such as the propagation of gravitation in Newtonian mechanics. Another charge of circularity against Kant’s causal theory (...) was leveled by Schopenhauer. His objection was that Kant’s approach is invalidated by the failure to deliver non-temporal criteria for distinguishing between causes and effects. I try to show that the modern causal account has made important progress toward a successful resolution of this difficulty. The fork asymmetry, as based on Reichenbach’s principle of the common cause, provides a means for the distinction between cause and effect that is not based on temporal order.Author Keywords: Kant; Causal theory of time; Anisotropy of time; Fork asymmetry; Principle of the common cause; Screening off.

The article explores epistemic and social conditions of the trustworthiness of scientific expertise. I claim that there are three kinds of conditions for the trustworthiness of scientific expertise. The first condition is epistemic and means that scientific knowledge enjoys high credibility. The second condition concerns the significance of scientific knowledge. It means that scientific generalizations are relevant for elucidating the particular cases that constitute the challenges for expert judgment. The third condition concerns the social processes involved in producing science-based recommendations. (...) In this context trust is created by social robustness, expert legitimacy, and social participation. (shrink)

We reconstruct genetic determinism as a reductionist thesis to the effect that the molecular properties of cells can be accounted for to a great extent by their genetic outfit. The non-reductionist arguments offered at this molecular level often use the relationship between structure and function as their point of departure. By contrast, we develop a non-reductionist argument that is confined to the structural characteristics of biomolecules; no appeal to functions is made. We raise two kinds of objections against the reducibility (...) claim underlying genetic determinism. First, some conceptual distinctions at the protein level cannot be captured on a genetic basis. A one-to-many relationship between DNA sequences and proteins emerges from them. Second, the relationship between genes and proteins is characterized by explanatory loops or reciprocal explanatory dependence. The presence of proteins is explained by the transcription from corresponding DNA sequences, and the latter is in turn accounted for by the action of proteins. By contrast, a reductive account requires a unidirectional explanatory dependence. (shrink)

The traditional mutual support of scientific progress and social advancement has given way to public reservation. Research is no longer considered worthwhile in general. Parts of the public have come to fear both scientific error and scientific success. This raises the question of how to deal with findings that could have a detrimental impact on society. In a different vein, fake research poses a serious challenge to science in that it could undermine the credibility of scientific accounts. Fake research actively (...) produces ignorance rather than knowledge (agnotology). The question is how such actively misleading approaches are to be identified and separated from usual scientific error. (shrink)

Kant's theory of matter is reconstructed and his views about and impact on chemistry are studied. His early "monadological" conception is analyzed and compared to other dynamical approaches of the period. His later attempt to regard matter as a continuum and to derive some of its properties from the interaction of forces is reconstructed. His conception of chemistry is examined and compared to the notion of some chemists who were inspired by Kant's work.

This Introduction to the Special Issue on “Responsible Research and Innovation” outlines features of the philosophical debate about the concepts involved and summarizes the papers assembled in this issue. The topic of RRI is widely discussed in science studies and has made its way into science policy. This SI is intended to make the contributions of philosophers of science more visible. The philosophically relevant parts of the field concern, among others, the processes of public participation in science and their impact (...) on the knowledge produced, the notion of justified public trust in science, and the idea of research pursued for the common good. Such topics bring social procedures together with epistemic and ethical considerations and thus raise philosophical challenges. RRI is subject to the tension between committing research to creating knowledge in harmony with public expectations, on the one hand, while not complying with public wishful thinking, on the other. RRI embodies a friction between serving people’s aspirations and correcting people’s expectations. This special issue is intended to explore the narrow pathway left between these conflicting demands.

Many nonhuman animals have the emotional capacities to form caring relationships that matter to them, and for their immediate welfare. Drawing from care ethics, we argue that these relationships also matter as objectively valuable states of affairs. They are part of what is good in this world. However, the value of care is precarious in human-animal interactions. Be it in farming, research, wildlife ‘management’, zoos, or pet-keeping, the prevention, disruption, manipulation, and instrumentalization of care in animals by humans is ubiquitous. (...) We criticize a narrow conception of welfare that, in practice, tends to overlook non-experiential forms of harm that occur when we interfere with caring animals. Additionally, we point out wrongs against caring animals that are not just unaccounted for but denied by even an expansive welfare perspective: The instrumentalization of care and caring animals in systems of use can occur as a harmless wrong that an approach purely focused on welfare may, in fact, condone. We should therefore adopt an ethical perspective that goes beyond welfare in our dealings with caring animals. (shrink)

The role mathematics plays in the sciences has been assessed differently and in conflicting ways. Put very roughly, a strong view holds that mathematically formulated laws of nature refer to or reveal the rational structure of the world. By contrast, a weak view denies that these fundamental laws are of an essentially mathematical character, and rather suggests that mathematics is merely a tool for systematizing observational knowledge. We put forward a position that combines features of both viewpoints. The tool perspective (...) is provisional and contextual, rather than ontological. (shrink)

PurposeTo evaluate the relationship between intraocular straylight perception and: (i) contrast sensitivity (CS), (ii) halo size, and (iii) hazard recognition distance, in the presence and absence of glare.Subjects and methodsParticipants were 15 (5 female) ophthalmologically healthy adults, aged 54.6–80.6 (median: 67.2) years. Intraocular straylight (log s) was measured using a straylight meter (C-Quant; Oculus GmbH, Wetzlar, Germany). CS with glare was measured clinically using the Optovist I device (Vistec Inc., Olching, Germany) and also within a driving simulator using Landolt Cs. (...) These were presented under both static or dynamic viewing conditions, and either with or without glare. Hazard detection distance was measured for simulated obstacles of varying contrast. For this, the participant was required to maintain a speed of 60 km/h within a custom-built nighttime driving simulator. Glare was simulated by LED arrays, moved by cable robots to mimic an oncoming car’s headlights. Halo size (“halometry”) was measured by moving Landolt Cs outward originating from the center of a static glare source. The outcome measure from “halometry” was the radius of the halo (angular extent, in degrees visual angle).ResultsThe correlation between intraocular straylight perception, log s, and hazard recognition distance under glare was poor for the low contrast obstacles (leading/subdominant eye: r = 0.27/r = 0.34). Conversely, log CS measured with glare strongly predicted hazard recognition distances under glare. This was true both when log CS was measured using a clinical device (Optovist I: r = 0.93) and within the driving simulator, under static (r = 0.69) and dynamic (r = 0.61) conditions, and also with “halometry” (r = 0.70). Glare reduced log CS and hazard recognition distance for almost all visual function parameters.ConclusionIntraocular straylight was a poor predictor of visual function and driving performance within this experiment. Conversely, CS was a strong predictor of both hazard recognition and halo extent. The presence of glare and motion lead to a degradation of CS in a driving simulator. Future studies are necessary to evaluate the effectiveness of all above-mentioned vision-related parameters for predicting fitness to drive under real-life conditions. (shrink)
